**Official e8400/e8500 Retail OC Thread

[jpcastro]

hi

few more tests with orthos:

E8400 - 9x478FSB @ 4300mhz 1,40v full



for 4,4ghz he needs 1,45v to be full stable.

regards

Wow... didnt it start on fire? What's cascade?

its a Vapor Phase Change unit

Q749A owners ?

Q749A owners ?

never heard about any one !

[GoThr3k]

Q806 doesnt seem to be verry good

1.39V 4.18GHz Superpi 1M Stable, this is done on the stock cooler

what is the exact batch nr ? Q806XXX I'm getting me 2 on friday hope to avoid this batch...

I would love to have a 4ghz CPU around 1.25-1.3Vcore level

I'm at 4ghz. Everest shows 1.42v and CPU-Z shows 1.344. Which one is correct =/

[zlojack]

What did you set it at in bios?

[Big Myke]

What did you set it at in bios?

VCore bios setting - 1.37500
Everest - 1.42
CPU-Z - 1.344

Motherboard = Striker II Extreme
Powersupply - PC power and cooling 1000W

Q806A045

[GoThr3k]

This is my Q806

what cooling and what are the other voltages?

[zlojack]

VCore bios setting - 1.37500
Everest - 1.42
CPU-Z - 1.344

Motherboard = Striker II Extreme
Powersupply - PC power and cooling 1000W

I'm inclined to suspect that it's the CPU-Z reading, given that vdroop is a lot more common than v-"rise"

But I'm not an expert on that!

[stephen23]

what cooling and what are the other voltages?

water cooling
for 4Ghz, Vcore 1.875 in BIOS(1.232 in windows), 1.2 FSB termination and 1.35 northbridge.
for 595FSB, Vcore AUTO in BIOS(1.496 in windows), 1.45 FSB termination and 1.8 northbridge.

Is that a typo or does your vCore droop from 1.875v in BIOS to 1.232v in windows @ 4GHz?

striker mobos report vcore wrongly for cpuz

my e8400 was confirmed stable at 4ghz with two other boards at 1.28v
for striker formula
set voltage 1.36v..
with loadline enabled
asus probe on load also shows 1.36v

cpuz reading 1.28v..

so no idea..

[vcp-cur]

anyone got a retail 8400 from newegg recently?
they have em in stock for $199.99

any results on those?
am wanting to pair one up with a dfi dk p35

[Rickpatbrown]

I bought mine on April 7. The more recent ones don't seem to be clocking as high. They require more voltage. I'm not gonna give mine any more voltage until I'm ready to replace it.

[vcp-cur]

so basically ... the good overclockers are the ones people got in the previous batches ? at launch etc ?

these new ones kind of suck ?

[zfactor]

same question i was about to pull the trigger myself on one of these and now im worried i will get a crap chip..

[vcp-cur]

well, crap chip is a bit extreme ... its the oc bug going trough us that want to see an actual 4ghz .. but oh well ... 3.6 ghz is more than I enough I suppose


edit: here , i got this from reviews on newegg
================================================== =
4/22/2008 4:04:06 PM Too Many years My first Intel


Pros: 3.6 right out of the box,Temps in the low 30s, 1.21volts Plus fast shipping

Cons: None Yet

Other Thoughts: Paired this with an IP35pro-8800GTX and 4GB G-Skill Good Bye AMD for now
================================================== ==

So basically just like i said 3.6ghz

sorry, should be 1.275!

[chief Dave]

Changed back to the E8400 last night from Q6600. I was 4050 450 x 9 @ 1.29 bios, played COH but failed prime fast (few minutes).

Now 1.30 load (can't remember what it is in BIOS @ the office now) and stable. On my 780i this chip benched @ 4.5 but with way more core.

Volts above line cal enabled, sb, sb 1.5 auto, core 1.31, vFSB 1.36, NB 1.55, strap auto, ddr 2.3 900MHz (dominators default 2.2 @ 1066 so I keep it set @ 2.2 in bios, MB over volts it .1, so I don't get a hang det ddr).

I'll start pushing it tonight and hope to see 4.5 - 4.6 @ 1.4 to 1.5. Thanks!

q807 - 4ghz at 1.296 :P
