wooo hooo fire that puppy up !!

[cincyrob]

well i hope i can join the club now. been tweaking my E8400 for the first time and trying to get it to 4.0ghz. kinda nervious about doing it .this is my first and only build so far and im still learning. but this is what igot right now. i had to adjust my vcore a few times to get it here. it is running OCCT right now and all is fine so far. also ran sandra burnin and passed with flying colors.

CPUz





OCCT is still running has about 22 mins till finished. then im gonna fire up Orthos and get it going good there.

i Upped my vcore up to 1.3685v to finally get it stable(so far)
upped my MCH +.1
upped my FSB +.1

i was worried about my mem not handleing the 450mhz so i droped it to 445mhz. all is well and im running my mem at 4-4-4-12 2t 1:1 ratio.

guess i need to change my sig now..lol

[Leeghoofd]

helppp :P

Drop multi to 8x plz...try again... Could be windows is corrupted due to the numerous lockups...

If you look in the P5KC thread some users think the 2 latest biosses were a complete waste maybe good idea to flash one or 2 versions back...to 0903 then

Bummer the settings didn't work

...hmmm...ok...i use the 8x multi...if this settings are not working i try to flash the bios...i find the bios flash on www.asus.com ?...thanks...i come back in 2 or 3 hours from now ...cya.

Nice! i guess lotsa people still buying the E8400 when E7200 is best bang for money now lol!

Dunno mate about that, if you can get your hands on tray CPU's around 130 euro's for E8400 or 160 for E8500 I prefer to go that way and have a good clocking time....with 6mb cache

[rockfella]

There are some Golden E7200s in india that easily hit more than 4Ghz
24x7.

There are golden cpu's in each price range... most prefer (like me) the bigger cache...

qft.

ive have e7200, as well as e8500 and i can say the e8500 is far more gratifying. however the e7200 does come in handy as a backup.

how does one get on the wolfdales OC list?lol

[hsinhow]

I have a Q807 E8500 with Asus Rampage Formula and 4GB G Skill DDR2-1066.

Currently I am trying to push the E8500 to 4.2GHz with:

443MHz*9.5 with memory running DDR2-1064
Vcore=1.39V w/o Load Line Calibration (LLC) or 1.36V with LLC (Bios)
VTT (FSB Thermination Voltage) = 1.36 (Bios)
VPLL = 1.6V
NB = 1.61V

Everything are stable (benchmarks) but I am not too happy about the high NB voltage that leads to high NB temperature (~57 deg.).

Surprisingly, the most difficult part of OC'ing my system is to get stable windows boot up and restoring from hibernation. I use hibernation in day-to-day basis to cut down the Windows boot time (30 sec vs 5 min). I found that to get stable restore from hibernation, I need to have the above configuration (e.g. high NB voltage). (My test routine is 1) Restore/start my PC from hibernation 2) Run Super Pi 1M.) Without considering hibernation, I can drop every voltage by several notches and not affecting stability.

Another issue is Window boot up stability. I observed that sometimes my machine needs 2 boots to start with the first one crash right before the Windows desktop shows up.

Anyone has some insight about these symptoms? Does any one use hibernation?

@LeegHoofd i cannot install the latest bios flash because i need Asus DOS utility or something like that...i don t find the stupid program...

[CERO]

whats with this Wafer number and where can I find it ( on the cpu itself or on the box). And what is the assumption to be better the lower the number or the higher or there is no correlation?

VPLL you will need 1.50V, for this e8xxx 1.50V are more than enough! 1.61V to NB is too much.. try 1.41,1.43V.

do u have 2x2gb or 4x1gb ?

[hsinhow]

Thanks for your suggestion. I have 2x2gb. I tested them using Memtest86+ @ DDR2-1064 and it passed (~3 hours).

I have been trying to reduce NB and PLL voltages. However, in order to have stable hibernation restoring, this is the voltage it needs. I wonder if there are any other parameters (like CPU/NB GTL Ref Voltage?) can be adjusted to counter the high NB voltage.

The failure mode of after hibernation re-boot looks like this: Right after system restore->Super Pi->Select 1M->Run->Crash and Reboot immediately.

Does this scenario tell me something?

E3110 (Q815A398)


This one seems far more promising than 2 former Q802 - which barely broke 4G @ +1.4V.

Further testing in progress

Hi,
If you continue testing for one hour, does it still make it at that vcore? or do you need a bit more ?

[roger_h99.nor]

You mean letting Prime run for 1 hour or more?

I don't belive much in the 'chip-degradation' theory. Maybe over 1.45V we may have a problem with degradation - in the long term. But this is still to be seen.

AMEN to that.

ive been hearing so much about the degradation of the CPU it has actually kept me from trying to get 4.0ghz. but there is no proven evidence of this actually happening. at least i havent seen any.

@LeegHoofd i cannot install the latest bios flash because i need Asus DOS utility or something like that...i don t find the stupid program...

AFUDOS

Go to Asus downloads, select your board type then go to BIOS Utilitys & download it.

You can download it from the ASUS website. Furthermore, [from what I remember] shouldn't be included as an option within your BIOS under TOOLS? I know the X48 and P45 boards made by ASUS have it.

You were already added mate

There's no EZ flash in the bios or doesn't it want to downgrade ?

[killerbee0704]

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

Nice and waiting for your results

i guess u will need about 1.43V on NB for 445fsb 2x2gb

@ Leeghoofd

If I show you a screenshot with Orthos running for 1hr+, a SuperPI 32M completion, Aegis Panel [BlackOps user here] showing actual voltage, and CPU-Z showing everything else you might need, would that get me on the spreadsheet?
