**Official e8400/e8500 Retail OC Thread

[suur_raul]

I bought E8500 FPO Q826A553 what you think, what it would do?
I can't try it out, because my PSU is coming next week.

[politenessman]

just a heads up, the newegg nj warehouse is shipping E0 e8500's. i ordered one yesterday and got it this afternoon (the newegg nj warehouse and ups are in the same industrial park, and i live about 5-6 miles away in nyc so i get everything overnight).
S-Spec SLB9K
Batch # Q822A549
Pack Date - 08/06/08 malaysia

first boot at 9.5 x 460, vcore = 1.31v, priming now. didnt try any lower vcore, just fooling around. pics and ss later. decent chance you will get an E0 if you order soon.

[LagunaX]

You should be able to get 4.4ghz @ 1.32 and 4.5ghz @ 1.36v stable.

[politenessman]

my first sub 10 superpi. now i can retire. with massive vcore and air cooling.



does 3d, and also played tf2 for a few hours. but no prime. i think one of my stix of g.skill ddr2 1000 is going bad.

Is that based on the batch number?

[politenessman]

yea, how do you figger?

[LagunaX]

My e8500 e0 is a q822a553 - shouldn't be that much different hopefully - thant's what i get on mine with a xigmatek hdt, link below:

nice chip. mine is q822a549, pack date 08/06/08. i got 2 more yesterday i am going to check out.

[LagunaX]

Anyone play with the retail E0 e8400's yet?
I am tempted to get that Fry's combo deal for $149 this weekend.
However, if they are mostly 4.2ghz and not 4.3 or 4.4ghz chips on mid 1.3v then wouldn't be worth it for me.

[zlojack]

Well, don't be so sure.

My first E8600 was a Q820A596 and it struggled to get to 4.2 stable at 1.36v while my second is Q820A597 and it is at 4.4GHz at 1.36v.

[zodden]

Got in on the Fry's deal and got my E0 stepping 8400 yesterday. First shot 4Ghz at stock Vcore. (stock for this chipset, P965) Man these are nice Ignore CPU-Z Vcore, check abit Uguru. CPU-z always gets it wrong, with every cpu put into this motherboard.



I wonder how high I can take it with this QuadGT (P965) motherboard? I am pretty stunned. I expected a blue or freeze and just tried it for fun. Stock voltage? Wow.

[anzial]

Did you look at your cpu-z? Doesn't look like stock volts Abit thingie might be wrong, after all

[zodden]

Ya, every CPU put into this motherboard gets read incorrectly with CPU-Z with regards vcore.

I would never set my vcore that high, at least not yet

Its set to auto and reading 1.25 in bios

[anzial]

Set it to 1.25 manually in bios and see if still works at 4ghz I don't know about Abit, but Asus sometimes overvolts everything when oc'ing with all settings on auto

Abit uguru software (thingie?) is extremely accurate for reporting voltages on abit mobos.

[zodden]

Just set it to 1.25 user defined and still here CPU-Z changes my voltage every time I reboot. Its now reading 1.504 as opposed to 1.528 in the screen shot. For whatever reason with this motherboard it always does that. I stopped looking at that 15 months ago when I installed this motherboard.

Going to try for 4.1 Ghz on stock. (no deal froze up while loading OS) O well now for the hard part. Time to start ramping up and moving up to find my limits. I am sure the ram will crap out for me before this cpu does, but we shall see.

you are about 5 or 10 versions behind. get a new cpuz.

[zodden]

Just installed 1.47, same stuff. Its not CPU-Z, I think its this motherboard. Others on the Abit forums have had the same stuff with vcore readings off CPU-Z.

E0 E8500 Q822A544

Quick test, water cooled. Not lapped.

[anzial]

What's the voltage in bios, dnottis? do u think 1.35 is safe?

[LagunaX]

Hey Dnottis,

what NB setting are you using - 1.4v?

[dnottis]

What's the voltage in bios, dnottis? do u think 1.35 is safe?

Intel says 1.36v is the most you want to pump through these 24/7, so I dont see why 1.35v wouldnt be fine, temps are ok. The board is pencil vdroop modded. Load line calibration is disabled, 1.375v is selected in bios. Voltage doesnt flucuate at all.

Hey Dnottis,

what NB setting are you using - 1.4v?

1.25v

[dnottis]

Man these 45nm are sensitive. the first time I popped it up and ran 29 mins. Shut down Orthos, played some COD4. After I was done playing COD4 I started Orthos again, failed in 56 seconds. Now I know why I went back to my 65nm quad before.

Also, the P5K-E only detects the E0 chip correctly with Bios 1102. I've went back to 1013 and get an error on every boot that says "CPU unknown, please update your bios to unleash the full power of this CPU". I'm wondering if the stability issues are just cause by this bios.

I've gotten it stable again this time at 4418Mhz, 1.328v with my memory running full speed @ 1116 (I have DDR2 1100). It just passed an hour of Orthos. I'm gonna pull the chip later and check the IHS to see if its even level. I had a bunch of C0 E3110 and E8400s and do recall them being very sensitive where they were stable one moment then failed prime in a matter of seconds on the next run. Frustrating.

[zlojack]

I think once you "burn in" your chip it should do better. That was some of the issue with the whole "degradation" thing, if I recall correctly.

After a while it took a small bump in vcore for the same settings to be stable then the chips seem to be fine.

I just got my new Rig E8400 with a p5q deluxe and some teamgroup mems i managed to get to 4000mhz like in the ps i did a 3dmark 2006 and after it finished it restarted my pc seems like its to much for the stock cooler or am i wrong? was going on 1.3vcore on the cpu..



My mems are default i didnt change anything because i pretty much dont really know there the 2x1GB Team Group Team Elite 6400



Any ideas?
