The *offical* hexus opteron overclocking thread

[JimNastics]

u really need to test in windows m8 with all your hardware in. memtest+ althought it passes using test 5 or 8, you really need to do it in windows, coz it will prob fail in superPi, if its faisl superPi, prime will almost fail.

I am happy now, prime95 pass @ 6hours @2.9ghz 2.5,3,3,6-1t and also superPi pass at 1m/32m.

no to reinstall all my software now

Yes I appreciate that, what I meant was that at the moment I'm still trying to see if it'll get past the first bios boot screen! Obviously I don't need all devices in for that. I'm no where near testing for stability yet, of course I will test that when I've sorted my OC'ing problems.

[philyau]

what h/w u got m8?

[JimNastics]

what h/w u got m8?

Here we go:

Antec SLK3700 Case
Antec TruePower 430w PSU
Asus A8N-SLi Premium (1009 Bios)
Opteron 146 (CABYE 0540FPBW)
Gigabye G-Power Cooler Pro HSF
OCZ 2gb (2 x 1gb) PC3200 "Performance Series" RAM
Sapphire X800GTO2 (PCI-E)
Audigy 2 ZS
1 x SATAII Samsung Spinpoint 80GB
1 x SATA Seagate 250gb
1 x IDE Seagate 200gb
1 x IDE LG DVD-RW
1 x IDE Pioneer DVD

I've tested with bare bones and it's exactly the same issue, so it's more than likely not a power problem.. at least I think not :/

[slinger]

I dont think that psu is going to help you much, I could be wrong though!

hiya m8, first things first.

1, drop ur mem to 100mhz, thats DDR200. put ur cpu at 10x, start the HTT at 260. LDT at 3x, Vcore at 1.4v, LDT voltage @ 1.3v, dram at 2.8v, chipset @ 1.7v.

now go to superPi test at 32m, if it passes go to prime for >4hrs. if thats stable crank up the HTT by 10/15 mHz, and repeat teh tests until superPi has an error, then lower the HTT by 1 -5, repeat until superPi can do 32m.
then go to prime95 >4hours, if it doesnt pass then crank it down by 1-5mhz, then prime again until stable.

if its stable >4hoursu found ur max cpu mhz.


now for mem.

1, lower ur cpu to 7x, same voltages. ram at 1:1 at relax timings say 2.5-4-4-8 or lower start at 260HTT. now goes to memtest86+ and test the ram on test 5 (20passes) test 8 (5 passes) if it passes then test using superPi 32m if stable move to prime, like u did for the cpu.

then u found ur max mem. then combine it to ur max cpu speed. using dividers if nesscary to get ur max speed.

I know it takes the biscuit doing the tests but u need to test and test and test.

I did this this weekend all weekend and its paid off. as you u can see on my pic above.

you may need to tweak your mem as well.


but its all worth it, as my cpu is stable as fook now.

phil

once you found ur max mem.

[da_ging]

got my geil pc4400 UltraX today and im impresed so far , tho still have a fair bit of tweaking and testing to do ,i've edited first post with screens

[jimborae]

up the vcore....


looks like my cpu tops ou at 2.8 with the volts i can give it. im a bit disappointed to be honest but maybe i shouldnt have set my heart on 3ghz

CABYE 0540 FPAW

anybody else get FPAW? i think everybody ive seen had an FPMW

Yep I got CABYE 0540 FPAW, 3ghz stable @ 1.575, no problem.

What CPU Cooler you using?

[kushtibari]

Got a 146 CABYE 0540 FPAW as well - only stable at 2.950 but thats down to the mobo having low max volts and also undervolting - the most I can get to it is just under 1.55 - little bit more and it'd be fine although don't think it'll go any further. New mobo should sort it.

[jimborae]

What CPU Cooler you using?

It's in a watercooled rig, the cpu block is Swiftech 6002.

[Dav0s]

1.7v didnt get my FPAW to 3ghz, i sense something else is the problem....

[JimNastics]

I'm still struggling away to battle my problem... still not able to boot anywhere near 250htt or above even with the slackest of memory timings at 2T. Ordered some new RAM as a stab in the dark.

[jimborae]

oops

[jimborae]

Finally got time to post a pic of my overclock.

Socket 940... I think it lies!!1#

Very nice OC though, I can't wait to get my hands on one.

[davethechamp]

I see I am not alone in needing to dive my 146 some fairly large volts to get near stable at 3Ghz, I ended up setting 1.300v + 126% = 1.638 (1.584-CPUZ) just to get it stable enough to run sandra, super pi and 3D03 benchies.






Temps got to around 50c, so Ive gone back to my "normal" setting of 305x9 = 2745Mhz, for which I use 1.4 v. will see if I can get this to 2800Mhz, stable soon.
Can't complain, its certainly capable, and its virtually a FX57 speed for £110!
nice
