How well does your Opteron overclock?

[Mooyo]

Doh, sorry Supernade. Mines a 144, me thinks that's what the ??? are for.

DaveB, you seem to have hit the jackpot with our Optys, not to mention the very deep pockets!

eljefe, you could bump up the VCore by 0.025 V. Since you are on water, temps shouldn't be an issue in your case

zetachi, it could very well be that your RAM is crapping out, or that you may need to raise the chipset/LDT voltages a little bit.

Type: Dual-Core Opteron 165
Stepping: CCBWE
Best Stable OC: 2661 mhz (So far) (295 x 9)
Week: 0534
Vcore: 1.5
Temps: No idea, eVGA Temp monitoring is very bad
SuperPi 1M: 32.578s
Memory: 190 FSB 1t-2-3-3-8
If I had better memory and at a higher speed I'd probably hit under 30 sec SuperPi. Stock Settings SuperPi was 48.569s

Bloody hell! That is sweet. Heheh...I'm getting the exact same stepping from TankGuys, hopefully, I'll get good results like you. Since you got yours from TankGuys, I'm assuming its a week 0340?

Got my RAM set @ 100 3.3.3.7 and 1.5 vcore how much more vcore can I add on air and still be safe?

That really depends on your tempratures. Its a combination of high temprature and large voltage which causes big problems. I would not recommend anything over say 1.55V if your full load temprature is >50C. Before you bump up the voltage, use the tool provided by TheCoolest, to calculate your Max TCase i.e maximum temprature you CPU is specced for. I would not exceed that at any cost.

Well here I go...I guess I'm happy with it. My memory controller craps out on me at 251 FSB exactly.

Nope a 0543, just takes some time to find the sweet spot on the chip. Week 0534 does not seem as bad as people are making it out to be.

Try nF4_MyGuard. It worked on an eVGA nF4 SLi mobo I tested out.

Just got my 148 and in testing mode.

CPU Type: Opteron 148 (Single Core)
Stepping: CAB2 0545 CPBW
Best Stable OC: 2.92
VCore: 1.375*113% ~ 1.5v
*Temps: 38 load

Really liking how well everyone is OCing these.

*I only have one temp, my computer is always at 100% load and never idle.

That is not the problem. I alredy had Jetway's myguard and SpeedFan 4.27 both of which work. The problem is the temp monitoring itself.

Temps will go from 40°C Idel straight to 51°C 1 core load to 57°C 2 core load with no delay in between. Just straight temp jumping. Also increasing / decreasing vcore has NO EFFECT WHATSOEVER on temps. Also going from Stock AMD cooler to XP-120 also had no affect at all. Temperature monitoring on the eVGA motherboard just does not work too well. If I had to guess as to the true temps I would think around 10°C cooler than what is reported. Heatsink is not hot to the touch and if the chip is Prime95 stable at 57°C for real, I would be very suprised.

Just got my 148 still working on it but so far:

CPU Type: Opteron 148 (Single Core)
Stepping: CABYE 0542 FPMW
Best Stable OC: 269x11 2959MHz
VCore: 1.48v
Temps: 27C // 36C

 

[JRE]

CPU Type: Opteron 175
Stepping: CCBWE 0541 RPMW
Best Stable OC (so far): 2665 (9 x 295)
VCore: 1.35v x 113%
Temps:idle=29 load=38

One of my cores will do well over 2.7 but the other won't

 

[Ri0]

g0dm@n, you need to include your OC's.

 

[easygoer]

Does prime 95 test both cores? I've been running it almost comstantly for the past couple of days. How long should one run that program. It's been on for about 4-5 days and its only around 30% done. Am I correct in saying heat which would result from a voltage increase will do damage but messing with the clock speeds will only make the system unstable which is reverseable?
