Opteron temps in the 50's

[Maximilian]

My opteron 170 @ 2.6ghz 1.38/39 V reaches 56*C under full load with prime 95. Ive read plenty of people are getting loas temps in the 40's, why are mine so high??

I used the stock heatsink with the 4 copper heatpipes, and am now using an SI-120 with a vantec stealth 120mm fan, only seems to go up to 1100rpm though, could that be the problem?

Oh and in an unrelated matter, my opty wont go past 2.6 ghz, and it cant run 2.6 with ddr400, it has to be set at ddr333, but still manages a 1T command rate. Is it my memory holding me back? Ive never ever overclocked before.

 

[robertk2012]

So are you using the 333 divider or is that the speed your ram is actually running at?

What is your motherboard temp like?

Is the airflow through your case good?

Its probably the fan that has your temps so high.

What is the cpu temp at idles and under stock speeds and voltages.

If you can fix the heat issue you should be able to get it up to around 2.8 with a little more voltage.

 

[Maximilian]

Thats the speed the ram is actually running at, im using the epox 9npa+, it dident seem to have dividers, just a setting for the memory speed.

The temp of the mobo is 38*C

I have a P180 with front 120mm intake and rear 120mm exhaust, also theres a fan on top of the case, these fans are set to medium.

At idle stock speed the cpu temp is around 35/40, its currently at 50 but ive got the heater on.

Any recommendations for a 120mm fan that CAN run really fast but typically runs slow and quiet?

 

[nealh]

it has been shown the fan does not make a huge temp difference on the SI120..wish I could find the review

My load temps with SI120 and Nexus fan are 48/49C w/ 1.5v

 

[Maximilian]

So a 120mm 2000+ rpm fan wouldnt solve this?

Big difference between 1.5 and 1.39

Thats your divider. change it to 266 and see how high you can go.

my opteron 165 is at 2.6 ghz 1.525v and 52 load with 2 prime stresses running after two hours. i have the arctic freezer 64 pro. im gunna go water cooling to make it hit 3 ghz

 

[robertk2012]

Thats alot more voltage that I would be using.

 

[sgtBaker]

That voltage seems really high.My opteron 165 is running 2.6 with stock volts.

 

[ronnystrauss]

they are safe up to 1.625 volts

 

[robertk2012]

lol no they arent. Single core 90 nm A64 are. 1.5 is the highest I would ever tell anyone to even try. Stock is 1.35.

 

[atybimf]

I wouldn't do any more than 1.6v, MAX.

 

[ronnystrauss]

stock is 1.4 buddy

 

[ronnystrauss]

maybe not 1.625 i guess thats just with dual core opterons but i know 1.55 is safe on a a64 single core

 

[Maximilian]

Ive actually come to the conclusion that either A: i have a crap chip or B: it must be the fan, no matter what voltage i do it dosent cool down, no matter what speed either. Also it will no longer do 2.6 ghz (i didnt test it properly anyways), had to bump it down to 2.5 for prime stability.

 

[ronnystrauss]

voltages RAISE the temperature. you need a better heatsink....there are good ones...thermaltake big typhoon...xp-90 ...arctic 64 freezer pro

I know that, i mean if i undervolt the thing it has no effect. I have an SI-120, and have had the stock 4 copper heatpipe heatsink which is every bit as good as an XP-90.

note:the stock heatsinks fan is a 2500 rpm 80mm fan. Mine never went above 2100, so again a crappy fan IMO. Silent but not geared for cooling.

 

[ronnystrauss]

lowering the volt changes the overclock though. no its not....is that a joke....did you really just say that. take it back...every test in the world ( including my own) 100 percent disagrees. the stock heatsink wasnt NEAR as good although its decent if you wanna put it onan old chip

 

[Maximilian]

Dude this is the FOUR COPPER PIPE heatsink!! Its new! its not the stupid cube that usually gets shipped with an A64.

Read this

There is an actual review as well, i know what im talking about. Oh whats that? yes im right, the guy who replaced his XP-90 with it saw a temperature DROP

 

[ronnystrauss]

i know what it is i had one. it was a fluke dude

 

[Maximilian]

Found it!!!

Thats says the stock is on par with an aftermarket heatsink!! No fluke.

 

[ronnystrauss]

well im telling you from personal expirience my temps dropped about 15 degrees when switching

No, don't be silly. The SI-120 is a VERY good heatsink, especially because it accomodates 120mm fans. With that heatsink, and that size fan, you won't need a fast spinning fan. Thats the whole point of using 120mm, because you get more CFM for less RPM.

I'm betting either you mounted the heatsink a bit off, you have poor case airflow, or your room is just very hot.

At any rate, remount that heatsink no matter what, it can't hurt - and you may find that's all it was.

 

[Maximilian]

My room is very hot i like heat. But it is only 1000 odd rpm max, idle or under load, never changes.
