Opteron 165 temperature question

[Crashmaster07]

Hi all,
Having just got a opteron 165(thanks to all who helped with the choice!!), I have a few temperature questions....
Bit of back ground first...
CPU: opteron 165 LCB9E
mem: 2 x 1gb corsain XMS 3200
Grx: 7600GT
System: Shuttle SN25P

I've used AS5 as thermal paste, and am aware that it needs time to "settle" (any one know how long this process takes??)
Now, on to the temperature bit. I've got speedfan set up on the machine, and the motherboard CPU reading is 39C at full load on Orthos. I'm also using core temp, and this give me readings of core1: 49C core2:51C.
I am wondering which one I should be using as a pointer in terms of overclocking, and also what kind of temperature I want to be looking at for a max.

Cheers all
Dan Chambers

I would say the orthos reading is out myself, especially if the core temp is higher. I'd estimate around 10-20 degree error margin on the orthos reading, what are the idle temps like


I remember reading about the shuttle temp readings being wrong somewhere.

 

[Crashmaster07]

The idle tempa according to core temp are 32 and 31 C load is 49 and 50. Sound reasonable?

 

[lsg1r]

its more in line with my opteron 175 according to speedfan although it only shows 1 core temp and an aux which I think is the other core temp.
Theyre 26 and 34 respectively at idle which gives a cpu temp (I work more with this than core temps) of 34 idle which goes upto around 48 under load.

Opterons do run slightly hotter than an x2 anyways plus they are designed for a hotter environment due to servers so I would say the temps are fine.

Those are fine.

You'll find there's 3 temperature readings for CPU.

Core 0
Core 1
CPU

The core temperatures are from the actual core of the CPU. The CPU temperature is the standard one we're all used to seeing which is read by the motherboard.

None of them have any real reputation for being reliable. People are always saying to focus on the _change_ in temperature, rather than the actual temperature, as long as the actual temperature is reasonable.

Your temperatures though are well within any reasonable limits, and you could probably put a bit more volts in and up the speed if you wanted.

Your shuttle must be easily handling the heat from the CPU. I see very similar temps in a tower case with a ThermalTake Big Typhoon with my X2 4200+ at 2.75GHz on stock volts. You should be able to overclock your 165 by at least 25% without having to increase the vcore and the temps will likely stay below 60c.

 

[Crashmaster07]

Yeah, I was quite surprised by the heat handling capabilites. Currently running at 2484 (276*9) orthos testing, looking at 50 and 55 deg c for the cores. Where do you think I should limit the temperature to (knowing when to stop basically)? Haven't had to do anything with the Vcore yet to..

Most would say orthos load temp as high as 55c but I'm fine with mine up to 60c (even had it as high as 65c for a period of time during testing). You might want to download CoreTemp 0.94 and check what it says for the TCaseMax. I suspect yours will be same as mine due to having same stepping as my X2 4200+ so probably will be 65c.

I would say you're ok.

I ran an Opty 165 on a DFI SLi-DR @ 2.8ghz 24/7. Under a lapped Thermaltake Big Typhoon my temps were around 50 degrees C in CoreTemp.

I could get the chip to 2.95ghz but temps were approaching 60 degrees. These chips run very hot in general so don't worry too much!

Plus, remember that you're in a shuttle so temps won't be ideal.

Your temps should settle a little with AS5 and as long as you don't run over 55 degrees 24/7 you should be totally fine!

ive had my LCB9E X2 so hot in the past (mid lapping - did a test, she was badly concave and did a bad job mounting anyway) that the copper is a little discoloured (overheat cutout killed it when it hit 90c)

its still running fine now, and sits orthos load at about 65c / 2.94ghz.

if its stable, its most likely gonna be fine.
overhot will reduce its lifetime, as will over volts. but the life starts in the 10's of years... theres a lot you can take off befor your ever going to notice.

fyi - worst chip ive ever seen was an XP2100+, was run arround 2.4ghz/2V for a few years... it still does 2.3 ghz @2v, but NEEDS 1.8v to post at stock, and 1.9 for stability. (from about 1.6)
