Anyone running an Opteron on an XP-90??

I just got my Opteron and the temps are a little scary.

Last night I had my Opteron priming at 2.7 (270x10) 1.52v and it was priming fine, but the temp was way too high for my liking.

The CPU @ 2.7ghz was idling at 30*C, but when priming on both cores after about an hour the temp was up to 55*C! Way too high for me.

Right now, I am running 2.6ghz 1.44v and it is idling at 27*C and I primed it for 15.5 hours with no warnings or errors. The load temp during the 15hrs was 49*C. My cut off is 50*C for my CPU.

Is anyone running their Opterons on the regular XP-90? I have a Panaflo H1B as well. Is the huge discrepency between idle and load temps typical of Opterons and the XP-90?

I was thinking about getting the Thermaltake Big Water, but now I guess I have to!

I have the same heatsink and fan, but a single core. The temperatures are about 37C idle and 45C load at 2.8ghz with 1.45v, which look okay to me.

Yeah your temps look good. Idle looks a tad high, but I guess load temp is what matters!

The thing that I dont understand is that my temps are below 30*C idle, but when priming, the load temp skyrockets to 55*C when running 2.7.

I'm just wondering if this is normal, or am I doing something wrong? Something I can do to bring the load temp to below 50*C?

I'd really like to run my CPU at 2.7GHZ, but right now, I cant even Prime it to see if it's stable at that speed.

When i ran S&M on my 165 at 2.7Ghz with 1.52v, and an xp90 with a 92mm panaflo 47cfm fan, i was getting exactly the same temps as you @ idle and load ;)

the only thing i could recommend is a better heatsink if you want lower temps.

I have an Opty 170 (at 2.6 for now) with an SI-120, idle is about 35-37C and load is about 47-49C depending on ambient (assuming Everest is reporting valid temps, which isn't necessarily a given). If my numbers are accurate, then 55C load doesn't sound totally out of the question for a smaller heatsink and fan than I'm using.

Then again, pretty much anything under 55°C seems cool to me now...my old Athlon XP (1.466->2.4GHz) tended to idle around that temp :p

Heatsink is flush? On all the way? Are your ambient temps high? Lack case cooling? That could be part of it.

Ive run many different cpus on my old xp-90, which I recently sold. I use the stock 165 copper heatpipe sink now(Quieter and identical temps to xp-90).

My x2-3800, and opty 165 definitely never went that high for load. Your temps are still within spec. I never overclocked my 3800 or 165 that high so its sorta hard for me to say exactly. My temps were around 34C idle and like 45-48C load. One thing to know is, pretty much all optys start getting hot after 1.45 volts.

My opty 144 @ 2.6ghz with 1.425 volts ran at 34Cidle and 42-43C load with my xp-90. Which is pretty much what its at right now with my stock 165 cooler. Of course thats single core and not a 165.

I think I'm definately gonna get the thermaltake Big Water watercooler, I was just suprised at how high the temp got, I think I was expecting too much.

I guess 2.6 will do until next week.

Is there a program out there that will log my CPU temps? I am interested to see how hot it gets at 2.7 running 3DMark or FEAR.

Speedfan has logging capability. Im not sure if it does exactly what you want though since ive never used "logging". :p

Just exit the game real fast and look at speedfan to see what temps are. They arnt going to drop instantly. :p

IIRC OCCT will run a log, I thinks you can look at a time/temp graph over the duration of the test

Yeah temps get crazy with anything above 1.48v+, well that was my experience anyway

damn, those dual cores run hot as hell when overclocked! Might have to think about going water when i upgrade to dual.

Thanks, I'll check it out.

I pretty good air flow in the case, but I think SLI might have a little to do with the high temps. I'm gonna try and rig a couple of 80mm fans to blow over the HSF area and on my top 7800GT. (Bottom 7800GT has ACS NV5, so that's not the problem, but the top card only has the stock CO HSF)

2 sli video cards would DEFINITELY have a part in your temps. Think about how hot vid cards get at load, and you have 2 of them. Raises your case temps alot. Makes it harder for the heatsink to cool the cpu if temps in the case are rising.

speed fan logging works great. Just select logging checkbox under config for what you want to log (cpu1, vcorea, etc.) you have to highlight the item and a little checkbox will appear at the bottom.
it will create a .txt log in the speedfan folder.

Ok. Here's the updated situation.

I'm running 2.6GHZ 1.4v and priming on both cores as we speak. CPU temp is 44*C load and I am pretty darn happy with that.

If 2.6/1.4v is stable, I am thinking about foregoing the water cooling and just being happy with 2.6GHZ. I ran 3DMark06 at 2.6 and 2.7 and acored 7708 and 7779 respectively. 71 3dmarks is not worth $109 for the Big Water watercooling setup.

However... if I fail prime at 2.6/1.4v and have to run 1.45v and bear with 49*C load, I think it would be better just to get the watercooling and go for the gold.

What do u guys think?

Ask yourself "will i really feel the effects from the extra 100Mhz", the answer is probably doubtful.

Also its always nice to keep a dual core or any 90nm AMD under 1.5v.

You're right, 100mhz isnt going to do crap, as my 3dMark06 scores show, but then there's the issue of solving my SLI heat issues with a watercooler... :p

Prime is still going strong on both cores. If it's still priming tonight when I get home from work I think I'll pass on the watercooler, but still... If I have to run 1.45v to get 2.6 and still have near 50*C load temps, the water cooler just might be worth the piece of mind of not running redline (as far as I'm concerned) temps.

I would say stay at 2.6. If I had to choose between that and even 2.8 but have to deal with the temp issues.

d00d, 55C is not that high.

Till you start running around 65C, there's nothing to be paranoid about.

However, i'd just run it @ 1.44V (2.6GHz), since that's a large vcore jump to only get another 100 MHz...

exactly. Same thing for my opty 144. I run mine at 2.6ghz with 1.425 volts. I "could" run it at 2.8ghz with more voltage, but I prefer lower volts/temps. 200mhz is hardly any performance increase that I care about.

I always laugh when I see people go "Whats wrong with my overclock, I can only get it stable at 2.9ghz and I want 3ghz". Not anyone here but other forums. Thats just friggin idiotic. Sorry had to get that out. ;)

I'm the kind of person that likes to eek out every last bit of performance up to the limit so if my XP-90c can handle the task I will take my opteron 170 up to 1.55v if it makes sense. If not I am strongly thinking of watercooling because I'd love to have a quiet system as well as some more headroom for ocing.

in my opinion, maybe you guys should worry less about temps well within spec, and more about how long
your chip is going to last when such large voltage jumps produce such low gains...

alright boys...

HERE is the final verdict.

2.6GHZ 1.392v

26*C idle, 44*C load.

Prime stable. Not too shabby eh?

Not bad. Thats on xp-90 heatsink? I am amazed when people have below 30C idle temps. I dont get how people do that on air. :p
