**Official e8400/e8500 Retail OC Thread

I have a dumb question - I got my E8200 @ 4.05Ghz and SmallFFT can run for hours but Blend would fail everytime during the 30-40 mins range. I've increased Vdimm, Vnb, etc but with no luck. What could be wrong?

Have you tried bumping VTT/FSB Term, and maybe PLL volts?
Just a small amount though like 1.20v for VTT, and 1.60v for PLL.
This may be whats needed since your having to push higher FSB frequency
on a e8200. Also you may need to play around with your GTL Ref voltage.

Hey Guys just got a spanking brand new E8500 from tigerdirect yesterday. this thing is stable at 1.5V load 4.4ghz...can prime @ 4.5ghz, but it fails @ 30 minutes, and can boot into windows @ 4.6ghz and play games or run benchies. has been running prime so far for 12+hrs. will call fully stable once it hits 16hrs. and oh i need 1.29Vcore to run stable @ 4.0ghz. i think i got an average chip...considering its an E8500. my 24/7 overclock will be 4.0ghz at 1.29vcore.....

what is your vid shown on core temp and batch so ?

your ram is running too fast/tight without VDimm to support the FSB? Small FFT's works, but Blend Fails...

[TEDY]

mine degraded again.

That sounds promising for a sweet 24/7

I want to try one of these E8500s

[Hughyhunter]

also tried a 03,05,06 run with 1.5Vcore..still with air..

Very nice!

I got me a Q807A050, tray version, today.
Seeing some good results with Q807 batches, I was expecting some from it.

Guess I have a dud.
Only does 3750 at 1.296V, what a POS.
At 3800 and 1.296V, Prime crapped out after 10 seconds.
Just tested it for 1 hour, as it wasn't worth wasting my time on it.
Got my E8200 back in.

Whatever, better luck next time.

Too bad. I was thinking about going down to the shop tomorrow since they just got a bunch in and digging to see if I could find a good batch....

[Jupiler]

It was the only Q807A i found (by luck).

Checked in 4 stores and most of them were :

Q802Axxx (3 tray versions, 2 boxed)
Q805Axxx (about 5 trays)
Q808A120 (2 boxed)

Also found a couple of Xeons 3110.
Q805A165
Q806A227

think I might give a Xeon a try.

That sucks.. I can imagine how happy you was, when you found that Q807..

I love my Q807! It runs like hell. Finally sub 10m 32M, and still some potential left!

[Jupiler]

Most impressive, xxx (damn', I forgot your name )

4700 with only 1.480V,
I'm still angry at myself for not getting one of those from HPM.
But as usual, it's a crapshoot. I might have gotten a dud one too, you never know.

But I still have my nice E8200, hehe.

[jpcastro]

alo

here is mine E8400 after some tests:

E8400 @ 4662mhz 9x518
P5K-E @ 1012
TG Elite 2x2GB e @ DDR1036 2,10v







nothing special but not so bad at all either

Thanks but Foxconn Mars does not have such settings.

What'dya think fellas? Try for higher OC?

[F0rr3sTT]

My 1st quick try, meager compared to others, but an improvement on my e6850 @ 3.8 that gave me ~13s 1M SP. And at $480 for the cpu ($220), mobo($60), ram(50), hsf(55), and psu(95), I'm pretty happy so far.

No... your good. Nice low volts. You dont want to ruin that. I never got my 1.375 back after messing around trying to go higher... but if you are like me you will want to max this sucker out and see what it can do. I did suicide runs with 1.6v 3dmarking trying to break my own record. It's fun!

My Orthos Beta always give me a wrong speed way off. For example if i'm at 3.8 it indicate 4.5 ghz ... very weird..

Orthos and windows will give a whacked speed as they always see the default multi. If you run 8.5 by 400 say, they will report 9x400 speeds.

[resyn]

Well, I couldn't help myself, so last night i went 525 x 8.. Here we are :
Gonna keep orthos running for awhile longer, that 1.340 is with 1.3850 set in the bios. First vCore I went with after upping from 450 x 9..

[Infa]

Think that's the best chip here at XS atleast

what a golden one!

[MrBeer]

Got My P5E and E8400 running at 4005

All stable on 1.39 bios say 1.45

[Jupiler]

Decided to push my E8200 (Q740A621) a little more and see what it would do.
So far, it doesn't look that bad at all.
Ran Prime Small for 6 hours at 4300Mhz and 1.344V, Prime Large is running for almost 3 hours now.
The custom package will be ran afterwards.

4300Mhz, 1.344V :

[Jupiler]

Prime Large at 4300 seems ok too.
Off to bed now, more testing tomorrow.

[ThatGuy16]

Golden!

I'm getting new ram next week, can't wait to see what this thing can bench
