Cool Can't help myself - another Core 2 Duo thread

With pending Intel Core 2 Duo cpu price cuts coming April 22, I am sure some of us will be tempted to buy and try some more core 2 cpus very soon

So why not a single thread here to post what new intel cpus you buy/intend to buy very soon ?

I'll start with the arrival today of my new 2nd hand E6700 L629B079 batch dated cpu. I'm very happy to see the shape of the IHS is similar to my X6800 with the 4 corners stamped a bit lower than the inner IHS area. It should have decent temps I hope

The E6700 L629B079 sSpec is a SL9S7

http://processorfinder.intel.com/det...px?sSpec=SL9S7

LGA775
65 nm
B2
06F6h
65W
60.1°C
0.850V-1.3525V

These parts are PECI enabled.

These parts have Tdiode enabled.

These parts have Extended Halt (C1E) power of 22W.
E6700 L629B079 cost me AUD$465 purchased from OCAU member Ka0sX



Compared to my X6800's similar shaped IHS


First board to try E6700 on will be P5B Deluxe with Swiftech G4 Storm water cooling, then try other boards with a brand spanking new Corsair Nautilus 500 from Corsair.

Re: Can't help myself - another Core 2 Duo thread

woah nice E6750 and 4 of them too... can't wait to see how they fair

Just started testing this new E6700 L629B079 and probably not as good as any of my other core2 cpus needing 0.07v to 0.10v more vcore to load into memtest86+/winxp pro sp2 @3600Mhz but this cpu is going on Kayl Black FrozenSS hehe.

E6700 L629B079 B2 Retail

Room temp = 24.5C to 25.5C

Orthos small FFTs load


Post load idle


E6700 L629B079 B2 Retail
- 3600Mhz takes 1.4v to pass memtest86+ and 1.425v to load winxp pro sp2
- 3600Mhz takes 1.480-1.488v for orthos/prime stable

E6700 QPGA B1 ES
- 3600Mhz takes 1.30v to pass memtest86+ and 1.325v to load winxp pro sp2
- 3600Mhz takes 1.35 to 1.38v for orthos/prime stable
- 4001Mhz @1.66v max Super Pi 32M

X6800 L627A872 B2 Retail
- 3600Mhz takes 1.35v to pass memtest86+ and 1.3625v to load winxp pro sp2
- 3600Mhz takes 1.37 to 1.39v for orthos/prime stable
- 4092Mhz @1.65v max Super Pi 32M

E6600 QPGE B1 ES
- 3600Mhz takes 1.35v to pass memtest86+ and 1.3625v to load winxp pro sp2
- 3600Mhz takes 1.36 to 1.40v for orthos/prime stable
- 4043Mhz @1.64v max Super Pi 32M

From my previous testing, I've found core2 cpus need ~0.05+ vcore more for orthos/prime stability then what vcore is required to be memtest86+ stable. So this L629B079 probably needs at least 1.45v vcore to hit 3600Mhz in windows.


Update:

@3729Mhz at 1.592v

Orthos small ffts load temp = 60C coretemp reported



Post load idle temp



My other core2 cpus seem to be better and would be around 3830-3950mhz at such vcore.

Interesting in bios if I enable PECI (Platform Environmental Interface Control), the bios temps drop my 10C and AI booster windows reported temps drop by 10C too but coretemp still reports same idle and load temps.

Looks like this E6700 L629B079 will fall short of the 4Ghz mark on water cooling. Only managed single Super Pi 32M @3900Mhz at 1.672v but idle and load temps are very cool!

I ran Super Pi 1M, 4M, 8M, and 32M with 4x cpuz windows open + coretemp + memset and AI booster applications opened at the same time and took screen captures at the during and after each run (except for 1M).

@3900Mhz at 1.672v


Super Pi 1M



Super Pi 4M





Super Pi 8M





Super Pi 32M





Times are alot slower due to running 1:1 instead of 2:3 etc and all the other apps open simultaneously though.

Re: Can't help myself - another Core 2 Duo thread

I've Currently got the following:

E6700 - L629B326
E6400 - L624A774

With the E6700 having done 4GHz validation on air (Noctua NH-U12F) and taken up to a 550FSB validation with the Asus Commando (don't have voltage records on hand ).

I'm still getting to know the E6400 (currently in a P5B Deluxe) but so far it's up to 3.4GHz on fairly low volts - 1.350v BIOS set on a non-vdroop modded P5B Deluxe (droops like a *****!) with a Noctua NH-U9 + NF-S12-1200 for cooling.

I'm just finishing up some further tests on the E6700 system and getting to know the E6400 based system a lot better and they should both be going under my Frozen SS some time within the next 7 or so days

With the price cuts I'm really not sure what I want to get. A part of me wants to have a play with an E4300 or E4400 (unlid it, BSEL mods, phase fun etc) but the other half is saying to save up some more cash and drop it on a Q6600. I'm really keen on benching with a quad core though I also want to update my main office/gaming PC also (however if I'm benching the Q6600 the E6400 can live in my main pc )

I agree. I saw a site today based in CA, USA sell out of them today according to their online stock indicator. If their posted info was correct, they sold 5200 or so E6420 CPUs in the past 24 hrs

I'm digging the OC potential along with the 4mb cache.

Seems like Aus retailers have quite a bit of stock. hmm... no I really shouldn't... Why did this Xeon have to be such a crap clocker!?

Sell it off to a more average/light user on OCAU

I will contemplate whether to get a 6420 once I see some more results, which shouldnt be too far off
