Intel Core 2 Duo E6750 Preview

It hasn't been a full year since we saw Intel launch their Core 2 Duo processors, but we will soon be seeing a line-up refresh. This is one product that really needs no introduction, but seeing as this is a refresh, refreshing everyones minds seems appropriate. Intel launched the Core 2 Duo to much fanfare last July. Months prior to this, enthusiasts were drooling over leaks of performance reports, which fortunately, turned out to be right on the money.

The entire Conroe line-up is built on a 65nm process, with the mainstream products offering 4MB of L2 cache. Improved over the previous Pentium 4/Pentium D line-up was better power efficiency resulting in a lower TDP and better overall temperatures. This is appreciated, as two cores under the same IHS can potentially create an unwanted room heater.

All but the lowest end Core 2 Duos take advantage of a 1066FSB. This is where this refreshed line-up comes into play, as it ushers in 1333FSB computing. This noticeable speed bump is all done while retaining the same TDP.

All Conroe 1333FSB processors are identified by by a 50 at the end of the product name, hence E6750, which is effectively taking over the spot of the E6700. Nothing has changed except for the FSB and speeds, except the ratio of course, which had to be altered in order to compliment the upgraded frequency.

One thing that should be cleared up is that most overclocking enthusiasts have already accomplished the same speeds we are seeing today, with most being exceeded. In fact, there is nothing stopping anyone from popping in an E6600 and overclocking using a 333FSB and 8 multiplier. That would effectively give you the exact same speed as the E6750 we are taking a look at today.

You might be wondering where the benefit is, with this official speed bump. Primarily it will benefit those non-overclockers most. There is no comparison to equal processor speed at 1066FSB and 1333FSB. That added FSB frequency should make a much more noticeable performance difference than the CPU frequency boost itself.

Intel Core 2 Duo E8400 3.0GHz - Wolfdale Arrives

In the summer of 2006, Intel released their 65nm Conroe-based processors, and to say they won the hearts of many would be an understatement. It was one product-launch that Intel didn't want to hit lightly, especially since AMD were actively taking from their customer base - on the enthusiast side, most notably. When said and done, Intel did accomplish what they planned to do. They put the industry through a blender and showed us how to be excited about processors again.

Although frequencies with Conroe were not as high as what we were used to seeing from Intel, the folks in Santa Clara proved that a high frequency didn't mean much if the processor itself was inefficient. Indeed, a 2.4GHz Conroe Dual-Core proved just how much better an efficient processor could be, and it quickly became the most common processor choice for the enthusiast.

The following summer, follow-up processors were released, including the E6750 Dual-Core which we evaluated at the time. Besides speed bumps, those processors didn't bring much to the table in way of new features, except for native 1333FSB support. Instead, the processor we are taking a look at today is one of the few new models that effectively replace the Conroe-based chips that we came to love so dearly in summer of '06.

I won't delve deep into how 45nm improves on 65nm, as I explained all of that in our QX9650 review, but I will touch on things briefly. One large benefit that comes with all die shrinks is better power efficiency and lower temperatures. Chips have the capability to run just as fast, if not faster, than their predecessors, all while running cooler and drawing less power. It's a win/win situation.

But with 45nm, Intel introduced more than just a die shrink. The biggest feature that most people will be interested in is the SSE4 instruction set. It affects media-buffs only - those who encode videos - but the performance gains are so evident, that developers of such applications are bound to begin supporting it sooner than later. The speed increases could be as large as 2x, even though it's difficult to believe.

Other improvements include increased L2 cache, half-multipliers (eg, 9.5x), a faster front-side-bus, improved Super Shuffle Engine, Smart Cache (to improve how split loads are accessed and stored) and so many transistors on a single die, it can give people headaches to think about it!
The obvious downside of the QX9650 launch in November was the fact that no other processors complimented it. Therefore, it was QX9650 or bust - until now that is. During CES earlier this month, Intel officially announced their 45nm launch plans, which include the desktop side, server and also mobile. We found out at that time that the Quad-Core models (Q9300 - Q9550) were pushed back to sometime in Q1. Although a solid date was never settled on, original road maps showed January as the scheduled launch. However, the rumor is that due to poor performing Phenom Quad-Core sales, Intel decided to hold off on the launch to help push remaining 65nm models to consumers first.

So how does the road map stand now that some time has past? Although Intel announced near-immediate availability of all 45nm desktop Dual-Cores at CES, only the E8400 has shown up on e-tailers. One popular e-tailer has the other models listed for availability in April. How true that is, I'm unsure, but it's strange given the fact that they were supposed to be available by now.

The biggest downside to the road map is that the Q9xxx are not available. Once they are, they are no doubt going to sell like hotcakes, given the improvements over the previous generation and the fact that the prices do not increase. The upside, though, is that even though the E8400 is the lone desktop Dual-Core to be available right now, we can be happy that it is the model most people would be after.

What makes the E8400 such a great choice is the fact that it's affordable, at $220USD on average, and has a nice clock speed. Let's face it... where overclocking is not concerned, having a 3.0GHz CPU looks better to the ego than say, 2.66GHz. It's all about the smooth frequencies, baby.

Motherboards


For any Overclocking one thing is must, ur Hardware supporting Overclocking, mean u have a C2D but one Intel 946 / 965 based board, will mean no OC… as those boards doesnt allow OC…

Good Well Ventilated Cabbinet is needed as will generate a lot of heat for sure..so, large cabbi with few FANs so, for OCing high u will need to have cabinet modifications….
Better RAM, those Value rams of 667 or 800 is good for Ligh or mid range OC but will need better RAMs for sure…

Last of all, the most important, The motherboard…. one ASUS P5B-MX motherboard with 946 chipset will not going to oc the procy better, where as P5B DLx with P965 or P5N-E SLi with Nvidia 650 chipset or XFX 650i or higher ones like P35 Chipset based ones like ASUS P5K series and nForce 680i ones like P5N32-E SLi or XFX 680i, will overclock far more efficiantly than those 946 based or VIA based ones….


Before we start, lets learn What exactly is Over Clocking ??

What Softwares One would need ???

Really dont have much idea about Linux softwares, so i would expect all running Windows will suggest few which u will need in Windows…

Lots of Software to monitor the Heat lavel !! As every one says Its easy to Overclock but easier than that to Burn the Procy

Install and Run it in every startup and then minimize it, will show one info at corner of the screen… Like my bellow Screeny,


Core Temp Run it while Stability test under load for Temps monitoring

Pi Testing to test the stability of the OC…

orthos This is for a long time load test of the OC system !!!

ASUS PC Prob… Find in in ur ASUS Mobo CD
in one dumb sentence, what we do is, we increase the FSB / BUS speed by little mean, which in place (FSB / 4 = BUS) increases the CPU Speed BUS x multiple = CPU Speed… and when u OC high u need to increase the processor vcore (my case Default 1.24) to some stable vcore by one step at a time !!! also at some point u may see ur RAM fails to keep up so, u need to increase their voltage too, chip value rams will not allow more than 2.1v at any point…In my case, default E6600 FSB is 1066 MHz where as BUS speed is (1066/4) 266.5 MHz, so with multile 9 my E6600 runs at 266.5 x 9 = 2398.5 MHz So by trial and error Method I found one Stable at this, as my mobo allow FSB increase so, FSB 1575 / Vcore 1.5v / RAM voltage 2.178v….

So, the main idea is increasing the FSB / BUS without givng more vcore till the point where u need to put some vcore… as more vcore will mean more Heat !!!

Lets Start

So to start with in ASUS Boards Disable AI Tuning and CIA2 for Giga Byte ones…

BIOS Settings

Seting the PCI Expres (PCIe) @ 100MHz / PCI to 33 MHz
Disable the Q-Fan control to allow the Processor fan to runn at full speed all the time
Disable any thing which says CPUID MAX to 2
Disable C1E if running windows XP (well thats what all ASUS mobo manual says)

RAM Settings

Well make sure processor and RAM frequency is unlinked so, i would suggest keep the RAM frequency to default value…Till the point u cant boot or dont get stable OS, u dont need to play with the RAM voltage of Timings, but b ready on higher Overclock u will need to push the RAM voltage up [Razz] i got suggestion that Voltage is fine Till 2.1v !!! nothing up for our value rams…
Processor Settings

Some motherboards will allow increase of BUS speed (BUS x multiple) some will alow increase of FSB (FSB/4=BUS Speed)…

in any case, increase step by step, dont push a lot at a time rather step by step… till u find one stable max point…

Stability Testing

Well sure, u should be able to boot in to OS… and personal Suggestion make sure its a clean installation without any Startup object or AVS, as that delayes the time of start nessecary Temp monitoring sofwtares….

If u are unable to boot, means some vcore or RAM voltage !!!

Run CPU-Z to view ur speeds…

for me 1st thing is running PC Wizerd and minimize it to Start bar as that would give a lot of info at once… !!!

Running ASUS Probe

Running Core Temp

they will give info of idle temp…. Make sure, u stay in side the temp limit (explained later on)

Now Copy the SUPER PI Process EXE on 2 places, run those together (Dont start calculation, just run those EXE)… now from Tank Manager, Go to Process, right click on each of the Superpi.exe and put one on each core…


Now Start calculaiton for 2m pi for both at once… !!!! keep eye on ur Temp limits (Explained Later)… If system passes the test fine, proceed to later on, if ur system restarts, means u will need to push some Vcore and come bacnk again to here, even then its restarts, then some RAM voltage may be (Dont cross that 2.1v) !!!

Now when u pass the test next level of Load test

Load Test

Run one Instance of orthos and Start testing ur Procy !!! run it for atleast 1 hour keep an eye on the Temps (Core Temp / PC Wizerd) all the time… if u are crossing the denger lavel Stop the test and rebott back to lower the vcore and BUS/FSB too !!!

if u pass the test means u have a stable overclock system !!!

Temparature settings

At Any point load temp should not cross 60c, see on idle condition temp may low at 42 ot 45 but onload will push the temp close to 60c…

your Dengar Level is 60c, allways stay bellow it….

Please note

No 2 Processo are the same, I mean I have one E6600 which need vcore of 1.5v to run at 3.6 GHz where as its possible that Mr. A’s E6600 can reach 3.8 GHz with just 1.48 or Mr. B’s E6600 cant go byond 3.4 ghx at 1.5v….

So no specific info on exact settings, u have to try and try to find best Overclock for ur self…

Remember Never let the Temps touch 60c, keep the RAMs at their Default Frequency, lavue ram cant take byond 2.1v voltage…

In the end I would say there are tons of better guides out there in OIverclokcing, Google will give better results, so those who already tried it, please post so tricks a tips for higher overlocks…

And last of all, Dont forget to post ur Results, with some Temp and load testing apps running at Backgroud… and with ur OC setings info and steps

For me, on stock it was 2.89 GHz, where as with ThermalRight ultra 120 extreme, FSB 1575 / vcore 1.5 / ram voltage 2.178 (667 MHz)

Intel® Core™ 2 Duo Processor

Difference Between Intel core 2 duo vs Intel dual core vs Intel Pentium D
Many people are confused what exactly the difference between Intel Core 2 Duo Processors and Between Intel Pentium D or Intel Dual Core processors….

I would try to explain from a END user point a view rather not going in to details architecture over view…

The Simple facts are,

All Core 2 Duo Processors are Dual Core Processors..
All Pentium D Processors are Dual Core Processors..
All Intel Dual Core Processors are Dual Core Processors…

Pentium D is nothing but 2 Prescott Processors side by side… runs very hot, not a good OverClocker…

Intel Core 2 Duo processors are next gen processors from Intel on 65 nm platform… developed from Ground up with new Architecture called Core… so they are whole new Processors just Jump like Pentium 2 to Pentium 3 or Pentium 4… Expect one Core 2 Duo Lowest End Processors like E4400/E4300 taking up and beating Intel Pentium D 3.8 GHz ones with ease … runs damn cool and super over clocker…

Intel Dual Core Processors are just launched striped down version of Core 2 Duos.. there are 2 in Market for Desktop range, E2140 runs at 1.6 GHz with 1 MB L2 and 800 MHz FSB and E2160 with 1.8 GHz with same specs of E2140…. these are not Pentium D rather they are same batch like Core 2 Duo based on the new Core Technology…. they perform same like Core 2 Duos but they were launched with a very low price to counter the market of super low cost but high performer AMD X2 range line up to AMD X2 4000

Intel Yorkfield

Yorkfield is the code name for some Intel processors sold as Core 2 Quad and Xeon. In Intel's Tick-Tock cycle, the 2007/2008 "Tick" was the shrink of the Core microarchitecture to 45 nanometers as CPUID model 23. This replaced the Kentsfield processor with Yorkfield.

The Yorkfield Multi-chip modules come in two sizes, with 12 MB and 6 MB L2 cache. The smaller version is commonly called Yorkfield-6M.

The mobile version of Yorkfield is Penryn-QC and the dual-socket server version is Harpertown. The MP server Dunnington chip is a more distant relative based on a different chip but using the same 45 nm Core microarchitecture. The Wolfdale desktop processor is a dual-core version of Yorkfield.

Yorkfield will be replaced by Nehalem based Lynnfield.

Yorkfield

Yorkfield (codename for the Core 2 Quad Q9x5x series and Xeon X33x0 series) features a dual-die quad core design with two unified 6 MB L2 caches, their product code is 80569. They also feature 1333 MT/s FSB and are compatible with the Bearlake chipset.[1] These processors were released in late March 2008 beginning with the Q9300 and Q9450. Yorkfield CPUs were expected to be released in January 2008. The release of Yorkfield, however, was delayed to March 15, 2008. Initially this delay was attributed to an error found in the Yorkfield chip,[2] but later reports claimed that the delay was necessary in order to ensure compatibility with the 4-layer printed circuit boards utilized by many mainstream motherboards.[3] At the Intel Developer Forum 2007, a Yorkfield processor was compared with a Kentsfield processor.[4][5]
[edit] Yorkfield-6M

Yorkfield-6M (product code 80580) are similar to Yorkfield but are made from two Wolfdale-3M like cores, so they have a total of 6 MB of L2 cache, with 3 MB shared by two cores. They are used in Core 2 Quad Q8xxx with 4 MB cache enabled and Core 2 Quad Q9xxx and Xeon X3320/X3330 processors with all of the 6 MB enabled. Q8xxx processors initially had no support for Intel VT unlike Q9xxx, but later versions all have VT enabled. Various Q7xxx have been reported online[6][7] and can be found in product change notifications, but were never formally announced. These have a very small L2 cache of just 2 MB and a lower FSB frequency of 800 MT/s, which means that their performance can be expected to be significantly lower than Q8xxx models.
[edit] Yorkfield XE

On November 11, 2007, Intel released the first Yorkfield XE processor, Core 2 Extreme QX9650. It is the first Intel desktop processor to use 45 nm technology and high-k metal gates. Yorkfield features a dual-die quad core design with two unified level-two (L2) caches of 6 MB each. It also features a 1333 MT/s FSB and clock rate of 3 GHz. The processor incorporates SSE4.1 instructions and has total of 820 million transistors on 2x107 mm² dies. QX9650 and QX9770 both are labelled as product code 80569 like Yorkfield, while QX9775, being made for Dual Socket 771 mainboards, uses product code 80574 like the Xeon X5482 "Harpertown" that it is closely related to.
[edit] Yorkfield CL

The OEM-only Xeon X33x3 processors with 80 W TDP and product code 80584 are made for Socket 771 like Harpertown but are only supported in single-socket configurations. Like the dual-core Wolfdale-CL processor, these will not work in regular Socket 775 mainboards but are typically used in blade servers that otherwise require DP server processors like Wolfdale DP or Harpertown.

[edit] Variants
[edit] Wolfdale

Wolfdale is the codename for the E8000 series of Core 2 Duo desktop processors and the Xeon 3100 server processor family. Released on January 20, 2008, the chips are manufactured using a 45-nanometer process and feature two processor cores. The Wolfdale models operate at 2.53 GHz, 2.66 GHz, 2.83 GHz, 3.0 GHz, 3.16 GHz, and 3.33 GHz; the E8xxx series utilizes 6 MB of L2 cache and a 1333 MT/s FSB. These processors include the SSE4.1 media extensions. Wolfdale uses a product code 80570. The E8000 Series of Core 2 Duo processors is one of the easiest and most popular Core 2 Duos to overclock, due to their low voltage requirements; and are known to hit 4GHz on air cooling with only 1.2V of vCore.
Wolfdale-3M

Wolfdale-3M is the logical successor of Allendale and uses the 82 mm² dies with 3 MB L2 cache similar to Penryn-3M, its product code is 80571. It is used in the Core 2 E7xxx series as well as the E5xxx/E6xxx Pentium Dual-Core and E3xxx Celeron processors. The E5xxx enables only 2 MB of L2 cache, replacing the E2xxx series of Pentium Dual core chips, the E7xxx series uses the full 3 MB of L2 Cache, and a 1066MT/s FSB, replacing the Core 2 Duo E4xxx series and the Celeron E3xxx series with 1 MB L2 cache enabled is the follow-on to the Celeron E1xxx series.
[edit] Wolfdale-DP
For the dual-processor server Wolfdale DP processor, see Xeon#5200-series "Wolfdale DP".
Wolfdale-CL

The Xeon L3014 and E3113 processors are Wolfdale-CL with product code 80588, in an LGA 771 package. L L3014 has only one core, 3 MB L2 cache and it does not support Intel VT, while E3113 is identical to E3110 except for the other socket. These processors do not work in regular LGA 775 based mainboards but are typically used in single-socket LGA 771 blade servers that otherwise require the more expensive DP server processors. Wolfdale-CL follows an earlier Conroe-CL processor, and Yorkfield-CL is the respective Quad-Core version of Wolfdale-CL.
