**Official e8400/e8500 Retail OC Thread

Telo - does that say 0.896v for 4.278.3Ghz ?

Nope, that is a bogus reading. I use 1.30v [on sig ]. For some reason CPU-Z doesn't work right when used on a BlackOps. We rely on the Aegis panel, which is why I apologized for not showing it since I knew it was going to confuse people a bit.

[Telo]

exellent speed for volts Telo !

tell me please does your aegis panel report correct cpu speed & fsb for 8 multi ?

Here is the 8 multi picture; if you want to see the 8.5, 9 multis go to the BlackOps OC guide thread [I posted all three of them there]. The report is spot on when it comes to the CPU speed:

[Leeghoofd]

I had this too with the MARS on the beta bios... really weird issue, only AEGIS panel gave the correct speed yet strange multies and FSB speed...all reaout programs gave wrong CPU speed indications here

Danmoody how are ya? didnt see ya at microcenter yesterday..lol

ok guys i got a E8400 OC'd to 3.6ghz my mobo is a GA-P35-DS3R. with F11 bios. outside of a slight increase to my vcore and takeing my mem(crucial ballistix ddr2 800) up to+.04
i havent done much more t oget to 3.6ghz. what might i need to do to get it up to the 3.8-4.0 range with air cooling or is 3.6ghz where im stuck at?

this is my very first build, i dont know a whole lot about it but i am learning..lol

[So3oL4Nu]

Stupid question, did you bump the voltage to your NB when you went higher than 400FSB/800Mhz RAM?

I increase the NB voltaje to 1.56 ...max is 1.7...i must increase it to max? ...please help me ppl...

[Telo]

I increase the NB voltaje to 1.56 ...max is 1.7...i must increase it to max? ...please help me ppl...

So you are running it at 4Ghz, with what FSB? if it is maxed at 9x I guess is about 445FSB; so 1.56v to the NB should be more than enough.

ive noticed alot of people talking about the batch numbers for the CPU's is there a better batch than another? or a worse batch that just wont preform like it should???

i just looked at my batch number for my E8400. it is Q807A190
good bad average????

From what I understand, E8400 Q807A190 is supposed to be real good.

That's supposed to be a good batch. Very good clocks at low volts.

I've got a Q814A335 on the way. I've seen good results from the Q814A, so we'll see if mine is a good one or not.

[cincyrob]

this is actually my second E8400 i RMA'd the first one i couldnt get it to OC past 3.4ghz, but hte problem i had was my crappy mem. but intel rma'd me a new cpu so i got this one directly from intel. ive had it up to 3.91 once ran for 30+ mins then crashed.
im runnning now at 3.6 with my vcore barely above the minimum volts 1.250v. so if i took up the vcore to say 1.355 i should be able to get 3.8-3.9ghz would i need to change anything else? to be honest i think my mobo isnt 100% compatible with the E8400. i have the GA-P35-DS3R. revision 2.0 i also think my mem might be holding me back some also.crucial ballistix ddr2 800 pc6400(2-1gb sticks double sided 16chip) not sure how much past 800mhz they will run.

[zlojack]

Well, I don't know too much about that board, but you might want to check for a bios update. That might help with chip compatibility. Depending on the exact batch and the cooling, a lot of the Q807A batch chips are hitting 4.0GHz on nice low volts.

Thank you database man!

[Mumid]

Got my P5Q deluxe today and an E8400 Q815A417, not many people with this batch but what results there are dont look too bad. Has anyone else got any experience with batch Q815A?

Only problem is the shop forget to send me my new cpu cooler and cant really be bothered to use the stock one so have to wait for that to come... so annoying!!

[Leeghoofd]

Also got an E8400 815 on the way , early results showed 4.3Ghz at 1.36 vcore so hoping to get sub 1.28 on 4ghz... will have the CPU on monday... keep ya guys posted...

Q815 should be the new stepping E0. Waiting for your results

Why do you think that? I thought E0 stepping was only available as an Engineering Sample right now?

[Leeghoofd]

Dunno I had an 816A044 too don't recall it being a special stepping... though I didn't look especially for it neither... willl see on monday mate...

[So3oL4Nu]

So you are running it at 4Ghz, with what FSB? if it is maxed at 9x I guess is about 445FSB; so 1.56v to the NB should be more than enough.

U're right...the FSB at 4GHZ is 445...the memory are running at 1:1 / 900MHZ ...i put 5-5-5-15/5-5-5-18...nothing ...the same error in orthos...i know that 1.56 is enougt for 445FSB...now the NB is 1.4 because the CPU is running on auto...x9 / 400/ 3,6GHZ...the seems the problem to be....a lot of pros here...can someone help me...? ...Telo i thank you...think something out ...found the problem ...i post again for all the people tommorow to see my problem...at the end of julie or the middle i buy a 2x1 kit CL5 1066...but look at my problem...probably you can help me...

First did you update to the latest bios ?

You tell us 1.33Vcore for 4ghz : is that in windows (cpu-z) or set in bios ? it's not because it boots in windows that it's enough for full load operation...

For the ram : did you disable transaction booster and static read control ? Ram voltage at 2.1 ?

Disabled CPU and PCI spread spectrum ?

For 2gb with P35 based mobo's 1.4NB is way than more enough for 450FSB, this is not a Foxconn Black ops mobo... no need to push voltages so high...

[roger_h99.nor]

Q815 should be the new stepping E0. Waiting for your results

Got a (E3110) Q815 yesterday - it's a C0.

Looks promising so far - runs Prime with 1.32 Vcore. Edit: at 4Ghz that is..
Further testing needed.

Had 2 Q802 earlier - they both needed 1.4+V to run Prime.

Hoep those are bios settings not load voltages

[killerbee0704]

I got a picture from one of my friend and he told me that is Q815A. I don't know it is ture or not

Yes, i have the latest bios...

The Vcore is 1.33 in bios...at load is 1.29 ...something like that...

I don't disable the transaction booster and static read control...

I don't disable the CPU and PCI spread spectrum...

...I try 4GHZ now...i post in 20-30 minutes if the options that you gived my are good...thaks man !...sry for my english again...



I tested u're settings...it didden't work ...

TRANSACTION BOOSTER DISABLE...i saw there is a value bettwen 0-3...i tried all...same blue screen on loadind end blue screen on log in...

STATIC READ CONTROL DISABLE ...like u say...i tried to DISABLE DYNAMIC CONTROL ...same errors...blue screen's...freezing image...

CPU & PCI SPECTRUM DISABLE

With those settings my pc si not stable...freezing image...blue screen....but there is a problem...now i can't load windows with my old setting....

x9

450 FSB

DDR 900MHZ 5-5-5-15

Vcore 1.3375

PCI 100

DRAM Voltaje 2.1

NB 1.4

With those setting 3,4 day ago i can run windows with no problem...i can use IE, Firefox...but the pc was not stable...now with the same setting i can't load windows...wtf ? ....

There are a lot of setting in bios...i don't know verry good to adjust them...my old E4500 i oc'ed alone...x8 / 400FSB / NB 1.5 / PCI 100 / Dram V 2.1...with those setting my pc run verry well...

helppp :P

[Chri$ch]

got today a E8400 Q816A322 and it seems to be a good clocker
