Sounds fun man, enjoy that!

Does any one test other E8400 batch Q814A226 or Q814A283??

[Blackoberst]

I had a Q814A218, not good at all. 1.35v to boot at 4Ghz, only SPi 1MB stable, lots of instability. I've changed it with a Q805. Results with Q805:

Woo.. thanks for the information. It seems I should looking for Q816A rather that Q814A283.

[HDCHOPPER]

like my 814

[killerbee0704]

like my 814

What is your Batch number??

[Blackoberst]

I've seen 2 or 3 good E8400s arround here(Q814) so that's why I also picked a Q814. But mine was not so good as the others I've seen, that's why I changed it with a Q805.

HDCHOPPER has also a Q814, check his sig.

[farksy]

I believe the Q807s are the best around now.

Totaly agree

Here's my Q807A Xeon..seems Ive gotten the same results with a few other chips. Wondering if it's my P5K-E limiting me. But I've got LLC enabled and a pencil vmod for droop. They always start needing alot of voltage about 4.1Ghz and the temps get hot quick above this.

Golden oldies - new E8500 Q740A479T straight from Intel to replace my E8500 Q740A493T



System:

• E8500 Q740A479T 2L7 / 1313
• CPU Cooling: Dtek Fuzion Rad Tower Box
• Asus Blitz Formula 1402 bios
• EVGA 9800GX2 stock hsf
• 2x1GB Crucial Ballistix Tracer PC2-8500 dual channel kit
• Memory cooling: 120x25mm Thermaltake 81cfm fan
• 80GB Hitachi 7K80 SATAII (WinXP Pro SP2)
• Pioneer DVD-RW
• 1200W Silverstone OP1200
• WinXP Pro SP2 Nlite Fully Updated.

So far this E8500 Q740A479T would have to be the best wolfdale cpu I've had on many levels including:

All vcore reported below are idle vcore with loadline calibration disabled, so there's a 0.08-0.016v droop under load.

• lowest vcore and max boot into memtest at 4218Mhz at 1.184v
• lowest vcore for 4009Mhz boot into windows at 1.184v
• lowest vcore for 4009Mhz 8M Pi at 1.192v idle/1.176v load
• lowest vcore for 4000Mhz prime 1hr stable at 1.240v
• highest FSB for 1M Pi at default CPU VTT of 1.10v = 540FSB straight boot from bios

4009Mhz 8M Pi at 1.192v idle


4000Mhz Prime95 1hr at 1.240v load


Super Pi 1M @540FSB at CPU VTT default 1.10v

It may well be the best you have had so far eva2000, but you may struggle to get it higher than this Q740A493T. By far the best one i have had so far is this Q746A579

nice that's on sub zero though... my E8500 Q740A493T hit 5320Mhz cpuz on 1/4HP and 4896Mhz on water

5003Mhz 3dmark for Q740A493T



Now this E8500 Q740A479T is better than my E8500 Q740A479T above - in terms of vcore needed for 4ghz prime and fsb on air/water

4602Mhz 1.408v idle / 1.392v load


Super Pi 1M with CPUZ and Everest running at same time




4408Mhz 1.408v idle / 1.392v load
Super Pi 32M with CPUZ and Everest running at same time


E8500 Q740A479T seems to have alot of potential

you Aussies always get the best CPU's Good one Sir George :p

Hi,

I´m going to buy e8400 today... could you please write me some batch numbers which are good for OC ( I see some Q805, 807, 809 here) or which one not to buy? .... Thanks much

Look at my signature I made an OC list of all the members here in an Excell sheet :

From the first page, Q807 is the best for 2008
Q807A050
Q807A191
Q807A241
Q807A261
Q807A269
Q807A276
Hope you could find the above mention batch number Good Luck and God Bless you!!

Leeghoofd, I have a Q805A695, not a Q810.
And the prime95 ss above is at 4.2Ghz@ 1.38v.

still pushing for 8's

Find some os tweak for Super PI,with your clock you should be 9.0,maybe 8.9's if push hard enough

[farksy]

Leeghoofd what do i have to make my chip go thru to enter your list ?

Orthos, pi ? Prime ?

ZenEffect just do max mem and tighten ram timings. 8.xxx shouldn't be a problem. Esp at that speed.

I'm thirsty a drink would be nice just gimme a screenshot of ya 24/7 speed and a screenie with some stability proof and CPU-Z or such to see the Vcore...

Add full batch list, mobo and cooling used
