**Official e8400/e8500 Retail OC Thread

[quattro_]

what do you guys think of this e8400 batch: q745a741
im about to buy it so please respond soon

never mine i found out it sucks and cant reach 4ghz

[zfactor]

arghh how does everyone get these 807a's??? i see soo many good ones in those and ive ordered 3 different ones and cant get one...

[Mtrx]

Hmm...could you run a quick FSB test with multi 6?

I wish but I can´t go for the highest fsb with this ram because only overclocks a bit, the best is 887mhz that´ll be my next step at 9,5x443 when I reach stability at 421x9.

Just an update... I did experience the dreaded burn-in or degradation with my E8400.

I originally was 24hr. Orthos stable at 4.1 GHz w/1.328V actual. Now, after a month and a half my OC has settled to 4.0GHz w/1.330V ish actual. It has been rock solid, but I did lose a little bit of my OC and it took a little bit more VCore. I'm still happy with 4.0GHZ for $200 though!. It also appears that any degradation that is going to happen, has already happened.

I noticed the samething myself yesterday. I originally needed 1.34 real vcore for 4.0ghz, now it requires 1.36 real for the same speed which means i'll be idling at 1.39vcore before droop. I decided to drop my oc down to 3.99 using the original vcore.

My Q745A567 does 4.0Ghz at 1.216v / load

E8500 Q807A
4270 @ 1.38725V BIOS STABLE
DFI X48 LT T2R
anyone knows what's the max voltage for 24/7 on E8500?

What is BIOS stable? How bout an hour or two Orthos? Then I'll be asking questions!

A fine batch... Just a bit older. I have Q746, it does require more voltage than recent batches but will get you to 4.05ghz and above (might!).

I had same problem. I was 1.375v @ 4.05ghz stable for hours the first week but after about a month it failed in 45mins. I had to bump up to 1.39v, which isnt bad but kinda sucks!

Could users with the new 45nm chips try using CPU-Z to report VID and compare that to what CoreTemp is saying?

If you go into the INI file for CPU-Z just set Sensor to OFF:

Sensor=OFF

and instead of it reporting your actual voltage it will display the VID of your chip.



I'm a little biased here as well. I just released RealTemp 2.5 which also displays VID and I'm interested in finding out which program is right. I think Intel and CPU-Z have a pretty close relationship and I tend to trust CPU-Z. I think CoreTemp might be reporting VID too low on the new 45nm chips.

Core VID 1.225 for my E8400 from CPU-Z

[laragirl83]

Just got my new E8400 (Q809A348), haven't pushed it too much, but whats for sure, it can do 9*400MHz@1.200V easely. Thats what I expected, tough
Will test it later...

[ante_ante]

Got a E8400 today with batch Q812A233, havent seen any around but it´s so good that i hoped. But 500x8 with 1.3250v in bios and 1.31 in cpuz seems to be stable. Haven´t tried any prime yet but for some gameplay it´s working perfect.

i'm thinking to buy Xeon 3110, coz hard to find E8400 right now...

is it good as E8400 ?

thx

Same diffrent names

I have yet to play with subtimings, and i just got some smartcoils for my loop, there were some tubes that were kinking pretty bad. So rest assured, when i beat these scores, you'll know.

You're right, man!

[ZenEffect]

what is considered high voltage id vs low?

i just recieved a E7200 w/ vid 1.1000, is that average? good? bad?

[ThatGuy16]

Looks like mine has "degraded" or had its "burn in" time. I tried to run orthos, it fails after 1 minute and a half.

Before it was stable at 1.216v load, now im priming at 1.23v load.

However! i have been benchmarking the past few days with voltage from 1.475v up to 1.55v (1.55v was not long, a couple minutes at most. Mostly 1.475)

I noticed before i could boot into widows at 4.6Ghz at 1.44v, now it needs about 1.475v, maybe less.

[barong]

mine , sorry i forgot the batch i will post soon

Same dang thing happened to me. I did a suicide run and never saw my nice voltages again!

[ThatGuy16]

I wonder if i do it again, if it will "degrade" more. Or if all the damage has been done... i love running 3dmark at 4.6Ghz

What voltages are you running at 4.6? I can get 4.53 working ok, but over that it heats up too much?
VCore:
PLL:
VTT:

[Leeghoofd]

You're right, man!

they might read out the VID better now (or worse), for my Qx9650 it's hilarious...

note : I added the older coretemp and for my Qx that seems more realistic... or you can say this CPU does 4ghz at almost stock voltage...naaaah



Will add the E8400 in the weekend when I get the CPU back

[Jodiuh]

Going from 4050 to 4095 yields a 5.9 rating for Vista on my setup. Is it the same for everyone there?

E8400 @ 4095 and quite cold w/ low volts still all around. It's not the super chip we've seen around here, but I did manage to "draft" him out of a few other higher MAX VID retail boxes from Fry's. I only wanted 4, this is all gravy.

[Mykou]

succeeded to raise my fsb at 568 on X48

( failed at 570 , freeze after getting vista desktop lol )

It's characteristic for these cpu's to need a little more vcore after they
burn-in. However after it completes the burn-in phase it will not (should not ) degrade further. I've seen this happen even at stock vcore.

After my CPU completed the burn-in phase it needed +.024mv to be
100% stable @ my initial overclock. I have since had it up to 1.6v (for brief
periods) and It has not degraded any further, and I check it regularly.
