Opteron doesnt overclock that much as 1 hour ago

[GoThr3k]

strange problem

1 hour ago, my opteron clocked at 3033 MHz
now, sometims it just reboots at 2.9 GHz

Is my opteron f*cked up??
or my motherboard??

[Major]

are you running on air ? I'll bet your room temps are up 10c

[5days]

Sounds like a stupid question but was it stable? And has your memory died?

[GoThr3k]

memory not dead, i putted it to 100 MHz and it stille didnt Pi @ 1M @ 2.9 GHz

chipset too hot????
burned my cpu???

[tennvols_69]

what are you temps reporting? and what board are you using. im willing to bet it either wasnt stable from the get go or its gotten a tad bit warmer in the room.

[M.Beier]

Hmm, sounds like temp's raised... Usually its the other way around actually, since the higher temp makes thermalpaste spread better @ CPU, but... A temp raise is a temp raise, and a bad thing for clocking :\

20 deg difference is 200 mhz on my rig :|

[geto]

Could have been just a suicide run and your chip isn't going to get 3 ghz.

2.9 is still very good, because really, for that extra 100mhz, aren't you splitting hairs?

[ozzimark]

chipset too hot????
burned my cpu???

considering you gave us no temps or voltages, it's hard to say

[Dissolved]

i doubt he did any stable testing..

Run:
OCCT
Memtest+
Memtest Windows
Prime95
3dmark01

Then come back and tell us if it reboots

[GoThr3k]

prime and occt fail even at 2.6 GHz @ 1.55V but i can run pi 32 for ever
it was 1M stable, at 3.030 GHz at 1.55V
but after that i switched the ram to other ram slots it started happening, gonna do some test soon
mobo is a MSI K8N sLI Platinum
temps arent correct i think, only 42°c at full load, no way

[ozzimark]

did you ever move the ram back? (sorry if it's a stupid question )

[4Qman]

GoThr3k,

im using the msi k8n sli plat and i have trouble hitting over 270fsb
with the latest 3.7 bios. What bios are you using to achieve over this FSB
mate. I can boot over 270 but fails prime.

No matter what multi or ram settings i use.

[dnottis]

It was never stable and will not be at 2.6 if you cannot prime or OCCT.

Here is my Opty superpi 32m at 1.45v @ 3000 Mhz.


But the max prime stable is 2940 @ 1.6v.


Your chip was never stable. OCCT and Prime it to find out what the max overclock is, then run it at those speeds and it wont crash an hour later. 2940 is really the farthest stable I can run 24/7 without crashing -

Wish people would actually test for stability before posting these suicide shots at 1M. 1M doesnt prove there is any stability.

[pcdoc1]

I'm I reading your CPUZ shot correct???? RAS# Precharge 2......

[GoThr3k]

problem is solved thoug
it is 1000000% stable @ 2.8GHz @ 1.45V stock cooler
stock cooler => TT BT
would be nice
which grid do you need for lapping??

[5days]

dnottis: My Opteron 146 does 2920MHz @ 1.40V (BIOS) 1.36V (CPUz) 32M Stable... and it also does 6 hours of Prime95 at the same speed and voltage. Dropping the speed down to 2900MHz seems to have it 24 hours Prime95 stable.

Maybe your motherboard cant handle a high HTT... hence 32M passing but Prime95 failing.

EDIT: Ignore that last bit you have a NF4 Ultra D.

Also I dont see why you are b*tching at people for showing their times (yes times... not stability) on SuperPi, because you are one of those people who use the voltage displayed in CPUz when we all know that DFI NF4 Ultra D's never have the correct Vcore displayed in CPUz... its always a fair bit higher... so dont come along and sh*t on everyones SuperPi threads when you too are trying to make your OC look better by using CPUz Vcore readings.

[dnottis]

I'm I reading your CPUZ shot correct???? RAS# Precharge 2......

Yup, thats correct!

2GB OCZ PC3200 GX XTC - also my 2GB OCZ PC4000 EB can run the same speeds / timings at 2.7 v.

GoThr3k,

with the latest 3.7 bios. What bios are you using to achieve over this FSB
mate. I can boot over 270 but fails prime.

No matter what multi or ram settings i use.

use the 3.1 bios, it is the best
+ maybe some more voltage to the chipset?? set it to 1.55 or 1.6

[dnottis]

Maybe your motherboard cant handle a high HTT... hence 32M passing but Prime95 failing.

I dont know if that was meant for me - SuperPI32M isn't nearly as taxing as Prime95 is.
