**Official e8400/e8500 Retail OC Thread

[GLENBOY]

i want to slowly stress this 8500....seems better than my previous 740A493...
i have it 4 days an max Vcore is what you see...1.32V..so far
4005mhz @ 1.232Vcore (previous 1.28V)
4100mhz @ 1.280Vcore (previous 1.33V)
4230mhz @ 1.320Vcore (previous 1.4V)
the V - clock scaling looks good to me..

looking good giorgos the e8500 is like rocking horse **it in the uk at the moment

Just got my 8400 today

[giorgos th.]

if you are prime/orthos stable you`re great M8..

I do think, as mentioned, that those core T are false.
My e6320 in the same system, idle core T were @ 20sss (1.4v)

As someone posted in another thread, Intel designed these core sensors to read extremley high core temps to throttle down the cpu when overheated. They apparantly were not designed to be used as thermometers or necessarily be accurate at lower temperatures. While some enterprising software designers have brought out programs to read these core sensors, Intel is probably not obligated to ensure their accuracy at low temps. Intel's own Thermal Analysis Tool does not work with the Wolfdale cpus.

mobo: DFI Blood Iron
memory: Crucial Ballistix DDR2-667 2x1GB
gpu: eVga 8800GT 512MB
cooling: water
psu: Corsair HX620
hd: WD250

vid: 0.8750

This is somewhat of an adventure. I had the latest BIOS from DFI but it would not allow me to disable EIST and the other CPU protection options. I would set vcore, multi, and FSB in bios but only the FSB would hold. When I launched CPUz it would tell me 6x multi and 456FSB. So I flashed to a beta bios found on T-Mod's DFI CD (give that guy a cigar). Now I can run the E8400 without any issues other than the temp discrepency.

My WC system needs a kick in the ass and my memory timings need some work but I will address those next.

Anyhow, here are 2 quick SS. This SMOKES the E6750 it replaced.

sofarfrome nice vid.Whats the batch?

Is this the lowest we've seen so far?

[Bail_w]

Is this the lowest we've seen so far?

0.85V – 1.3625V, so 0.85v is the lowest.

huh lol same batch but my vid is higher? what is your last four wafer numbers? i bought it from NCIXUS too

[Mithan]

I figured I would ask you fine people if anybody knows what the average Intel specifications for the E8400 Thermals are under idle and load and the core temp (if its different)?


I've been looking around but all I can find is people talking about their temps, not the actual recommended guidelines.

My board shows cpu temps ~15C higher.

you got the exact same vid and batch as i do, may i know your waffer #?

[MuffinFlavored]

CPU-Z shows a different clock speed, than Orthos and CoreTemp.

very nice CPU indeed

what about max fsb

[Super strokey]

Hmm board to choose for this cpu seems hard, blook iron looks decent on it, only one p5k ive seen though.

[Xvys]

I was wondering why my latencies are so crummy compared to some others here? My system is stable at 4275 MHz, so far.

[zizo]

CPU-Z shows a different clock speed, than Orthos and CoreTemp.

Loaded at 401 and clockgen to 467.
Here is a load at 467 and speedstep enabled.

What do you think is the best, cheapest P35 board for these?

I want to order a E8400 off the egg tomarrow, but i don't want to spend the $200 on a X38 that i had planned..

Would rather have a stacker + P35

[Super strokey]

Im wonder which mobo is best, im thinking the blood iron is awesome

Go for the P35 + stacker because X38 is not much improvement from P35.
