Why is my Opteron so hot?

[Ender17]

OK, I just installed my Big Typoon, using less AS5
it helped some, but I am still hitting 53 C stock volts 2.6GHz dual Prime95 stable

for comparison, my X2 does this speed at 1.5v and never hits 50 C

is this normal? what should I do?

[politenessman]

i installed a new ultra d yesterday and my temps with an x2 3800 and an opteron 144 at stock speed idle was around 48c, which is about 20c too high. my pwmic temp was reported as 62c(idle), with all my fans running, no oc, no overvolting on anything, also my chipset temps were about 10c too high. i installed the amd cpu driver, my cpu temps immediately went down to less than 30c, my pwmic went to 34c and chipset to 37c, which are better than normal. try this, hope it works for you, i tried everything else (swapped out cpu, psu, ram, vid, etc) to no avail, thought my new rev ad0 ultra d was bad.
good luck

where can I get this driver?

edit: if this is it, I already installed it

You used what drivers for the 144 opteron? mine is also really hot, but the heatsink is really cold

I must be an idiot then, I always spread a super thin layer over the whole IHS, I have never had temp problems doing it this way.

I have never seen it look like that in the first pic posted.

[politenessman]

there is a sticky at the top of this forum with links to this driver and instructions. if your heatsink is cold, but your temps are hot, you MAY have bad contact with your cpu.
i always put a small amount in the middle, enough for a thin layer a little bigger than the circumference of a dime when i spread it out. the cpu is in the middle, and my xp90 always spreads that small amount out to cover the whole ihs. when i use more than this, my temps go up, also i almsos always yank the cpu out of the socket when i take off the hs/f, and its a straightening out those pins.

The truth is that the exact way how you put paste on the IHS, how much and whether and how you spread it out doesn't do much with most pastes.

Some CPUs just have bad contact between die and IHS and then there is nothing you can do exact overclock less, RMA it or put it into your mother's PC.

[Ender17]

well it looks like I can do 2.6GHz at stock voltage, which means temps are only hitting 55 C
7 C higher than my X2 at the same speed, 0.15v more voltage, and a worse HSF

guess I'll just keep it since I've gone to all this trouble
maybe I can get watercooling or something in the future, but for right now I'm just gonna stay at 2.6GHz
it's not like I can notice the difference without benchmarks anyway

I did notice the surface of the 170 seems "less polished" than the X2, but I didn't check to see how flat it is or anything

you are using 2x 1GB of ram!!
Every processor that i test here burn with so much ram.. with 2x 512mb, my venice make 33C idle ~ 38C full.. with 2x 1gb, he makes 38C idle ~ 44C full!!

Yeah, I just noticed that too. After installing my new 2x1gb kit, my lidless Venice went up about 5C under load, compared to 2x512mb.

[Sentential]

You arent going to like what Im going to say but it sounds like your TIM1 is messed up (tim under the heatspreader)

I have a 920 that is like that (running 10c higher than everyone else) and bascially there are 2 options, RMA it or attempt to fix it yourself.

Personally if I were in your position I would take the RMA route.

[Careless]

im having this same problem with my 165.
but now that i read what you guys are saying, i think i spread waaaaaaaay too much AS5 on the thing.

Did you also heat cycle your AS5?

I noticed that on 1.375 volts on my K8NXP-SLi mobo, (although cpu-z says 1.4 - 1.425 volts) at 282 HTT x 9 im at about 2550 mhz, and I hit 54'C on dual-priming. Last week, i was hitting about 58'C... sometimes you gotta give the AS5 some time to cool down COMPLETELY is what i've experienced. i designated 3 days where I decided to stop my file transfers and let the computer rest for about as long as i sleep throughout the night. ever time i did it, i noticed the temperature got progressively less, by about 1'C a day.

my goal is to hit 2.8 ghz. i will settle with 2.6 ghz.

this is with a Hyper 48 heatsink with the fan modified to run at full 3500 rpm without PWM.

honestly though, this is my first overclock since 300A days.. and i know nothing about this stuff now. im just a huge n00btr0n, but after doing some arithmetic and synthetic benches and matching the FX-60 stock speeds... heck for 400 bux, i dont think i'm doing all that bad, compared to the price of the FX-60.

how do you fix TIM1?

[muzz]

how do you fix TIM1?

Buy removing the IHS, cleaning the core, and either applying AS5 ( or something else) and reinstalling the IHS ( glue), or just running the core naked.

No other way to get to the stock TIM without removing the cover.

I was afraid of something like that
man that really sucks too because it's a 0530 TPMW and there's no way I could get another one of these

I'll probably be coming back to Intel as soon as the Asus P5WDG2-WS is available

[uOpt]

Yeah, I just noticed that too. After installing my new 2x1gb kit, my lidless Venice went up about 5C under load, compared to 2x512mb.

I just tried this.

With my 2x 256 MB TCCD the temperature of my CPU is 1 C higher than with my 2x 1 GB UCCC. Same settings, all voltage and timings the same.

[187(V)URD@]

I got a 146 Opteron at 1.525 bios volts and a X2 3800+ at 2.7ghz at 1.55V bios volts.

On the same watersetup(not the setup in my sig) but the X2 is passive cooled on my rad.
Opteron idle/load: 32°C/44°C
X2 idle/load: 26°C/36°C

But the X2 gets higher PMW temperature.

Yeah, because that will solve all your problems See Sentential's post before your last.

[Ender17]

I don't expect it to solve the heat issue with this opteron, I want it for the 8 phase power and PCI-X slots

[loonym]

i'd rather see some of those temps than this misreporting expert. it's got to be low by at least 10c

[STEvil]

In saying this, are you insinuating that if you put more paste you will get better temperatures?

No, he is referring to the contact patch.

If you are then for me you are not correct. The amount of paste only needs to be enuff to create a thin layer between the IHS/Core and heatsink/block anything more is simply wasted, this is simple thermodynamics, not rocket science. Any results showing otherwise are because of other circumstances, this is my opinion, and its not open for discussion, lol

Well, you'd be wrong too. What you really need is a thin layer that fills any pockets or shows you bumps/uneveness in the heatsink base and/or IHS. If you lap both then you dont even need a TIM when you are using an IHS (and technically when using an IHS it doesnt help anyways if the heatsink base or the IHS are deformed).

Ender17, to be really sure you need to lap both the IHS and Zalman 9500, seeing tht the Zalman 9500 performs fine on your X2, then a lapping of the Opty would be needed, problem here is tht u loose your warrenty . I have found tht the A64 CPU's I have had, are not getting pressure from the heatsink in the correct place i.e. in the center of IHS because of shape of IHS and heatsink. Just imagine wht happens if the the corners of the IHS are higher than the center if IHS, the heatsink will be applying pressure to the corners, creating a 'vaccum' of pressure in the center. I think this is the reason we find many IHS with corners sanded down from the factory.

Ofcourse you may do everything you can to decrease temps, but in reality your chip is a not one, i think it all comes down to how much u want to know, wht the cause is

Might be he isnt supplying enough air from outside the case. ThermalTake Big Typhoon has problems as well if it isnt getting enough fresh air since air being continually recycled within the case has no chance to cool down... just keeps getting hotter.

The choise is obviously yours, and not a bad one. I was just pointing out switching to Intel will not make you immune from a poorly fitted IHS, plus you will need different RAM to make the move. I assume you know the A8N32 has 8-phase power, but I was curious what cards you have that require PCI-X and not PCI-e? A RAID controller or something?

yeah, a Broadcom RAIDCore BC4852

wonder how much I can get for this 0530 TPMW?

[v3n]

my 146 has reached 59C with occt but its rock stable and idles at 34c

[stone_cold_Jimi]

Never thought I'd say it, but I want a hotter Opty. I have another 146 CACJE 0546 and it's burning in at 2.8 GHz, 1.5v, 40C on stock HSF. The last one I had, same stepping, was so cold-bugged it wouldn't boot under Vapo LS. This time I'll try weak RAM drive strength and ACPI Multiprocessor. Cunning, eh?
