LagunaX > Yes Orthos also stable

[Leeghoofd]

Lol this is one of the best CPU's around mate, can you pm that shop plz... I WANT ONE TOO !!!

Okay pm was sending :hello:

[LagunaX]

Great chip kitkeman!
I hear that the q814's can do similar too!

[dr.noob]

LagunaX > Yes Orthos also stable

but he did the large stress, its not the same as the small ffts

I had my 8400 on the shelf for about a month, just pop'd it back in I cant get 4400MHz stable again on the same settings, more vcore is required, Backed the FSB to 478 and need more volts than I originally needed to run 4300MHz stable.
I did the Rampage mod, I wonder if the bios is requiring more cpu volts than the Maximus

hmm

don't think vey surprising , lot of people including me had to increase vcore to get their rig stable again .

IMO definitively seems those chips need a "burn in" time . ( had same thing with three wolfies )

[Darkatom]

nvm. Anyways does the e8400 perform better if used with a 8.5 to higher fsb ? Or does is have a minimal affect ?

[laragirl83]

Now trying to find the lowest voltage for my 24/7 setup, 9*400MHz.

So far, its prime95 stable @ 1.136V... going down more

[The[R]eaper]

hey guys Q13Axxx any good? thanks

[oldsarge]

Not mine! Q813A348 VID = 1.225, core volts for 4ghz = 1.35 (e8500)

[Leeghoofd]

Is that Bios setting or CPU-Z readout under load ?


Got my E8500 Q813A446 today ( Thx Nilos ) 3.6Ghz at 1.15Vcore (CPU-Z under Small FFT's load, no loadline calib or stuff on the P5K Dlx), 4ghz (9 x 450) at 1.28Vcore ( 1.3325 in bios) slightly worse than my E8400 but is about 8°C cooler



OC List updated lads

Leegthoofd....sorry, Everest reading at 100% load, checked with multimeter.

You got some bad luck there then mate, we got a few Q813A users here all around 4ghz around 1.28Vcore... but again 4ghz at 1.35volts who would have dreamt of that a year ago...

[mrcape]

Glad to see there are some good chips in these newer batches. I don't feel as spoiled anymore with my 745.

I will certainly jump on a e8600 when they arrive in shops.

Went through many posts but what would you guys say the average e7200/e8400/e8500 OCs are/?

[kitkeman]

Leeghooft >> Why I 'm not yet in the OC list ?

[zfactor]

anyone get a newegg 8500 in the last few days just wondering if its worth trying one more time for a e8500 my current one is a q805. i sold the q809 i had that one sucked. these newest 814's look to be very nice..

[Leeghoofd]

Leeghooft >> Why I 'm not yet in the OC list ?

Can you give us a small FFT' screenie plz (some peeps pm'd me that it will require more voltage to be stable small FTT's then with large FFT's)

Look here, way easier

and I definitively think it's true . small fft put more stress on cpu than others IMO. I 've often found stability under large or blend but failed after under small fft's unless I raised voltage for.

10k and 20k tests are the hardest imho

Q750A071 on DK P35 with the intel boxed cooler

[Mtrx]

Hello, few days ago I post the results overclocking this e8500. Then it reach 4200mhz with 1,328v under load:

http://img148.imageshack.us/my.php?image=1604ae1.jpg

I kept as it for 24/7 and gaming and didn´t notice any degradation at all since superpi fails few times so decided to retest with prime and this is what I found:

http://img520.imageshack.us/img520/4874/1701ftm2.jpg

With the same vcore it fails in 7 minutes.. so had to give +0,02v to the nb, raise a little bit the vcore and reach stability again:

I´m not sure if “burn-in” period already pass or I´ve to expect more degradation because just needs +0,016v to be prime stable, at least for now, is a bit messy the need of recheck time to time this cpu, probably the only way to know is keeping as it again 24/7 and see what happens.

[mrcape]

Yup 10kfft priority 9 seems to be the ultimate cpu test for me. I also like 1 hour occt cpu test.

[Darkatom]

I'm currently priming my e8400 at the settings below. I'm curious though if running such a high fsb 24/7 will cause any corruption, data loss, instability , etc issues ? The reason I ask is because i'm able to reach the same oc of 4.0ghz while using less vcore in conjunction with the 8.5 multiplier.

Current Settings:
4.0ghz
x 8.5 multi
470 bus
1882 fsb
vcore: 1.336 ( actual load cpu-z)
cpu fsb: 1.25
spp: 1.4
mcp: auto
All GTLs: auto

These Settings require more vCore:
4.0ghz
x 9 multi
444 bus
1778 fsb
vcore: 1.352-1.36 load
all other settings are same as above

Wanted to post this up, seems VID's might jump a little...

CoreTemp Version 0.99 - 18th May, 2008

- Fix: Incorrect VID detection on 45nm desktop Intel parts.
- Add: Support for Intel Core 2 Duo E7000 45nm series.

VID CoreTemp 0.99 reads is now the same as RealTemp 2.6.0
