Phenom II x2 550 Temps

post #1 of 12
Thread Starter 
Hello all, I made a thread previously about unlocking my Phenom II x2 550, I managed to unlock it so I figured I should make another thread about temperatures for it.

To unlock I used the "ASUS Core Unlocker" utility. I just pressed 4 at startup and now it says "4 cores successfully activated!" when I boot up. They show up in Windows and everything seems to be perfectly stable so far without any messing around with voltages.

The socket temp (TMPIN0 as far as I can figure out) seems to be about 4 degrees above the core temp, and as you can see the core temp got to about 66/67 degrees after 10 minutes of the prime95 blend test. Is that all right? It seemed to be still rising after 10 minutes but I'm not sure. Nothing adverse seemed to happen.

Thanks! Foaric

EDIT: I should mention that the idle temp is about 46 degrees going by the 4 less rule.

The stock HSF is not meant for a quad core, only a 2 core. Buy some good cooling, then temps won't be a problem at all. However, the temps you are getting ARE normal for an unlock, and so is the difference between the socket temp and the core temp. On my 560 temp, I can't even read the individual core temp anymore.

I can't actually read the individual core temps, I'm just guessing based off of the socket temp (it appears to be 4 degrees or so more than the core temp). I'm not planning on overclocking at all but I'm guessing 66 is too high?

I made a thread over in cooling to ask for some advice, thanks!

66-67c after just ten minutes? NO that's not normal or even close to being safe. 62c is the max safe temp while under load. And 50c at idle? You've got problems there my friend. Run it under these conditions very long and it will surely crap out on you.

Download Asus PC Probe and compare temps, you should be reading the cpu socket temps. Any thing more than 62c is taking life away from your cpu, and above 55c will probably cause instability.

Hmm I've disabled the unlocked cores, probably best to run it on two until I can find proper cooling then. I'll have to have a look around for a cooling solution. Though I'm not sure a better heatsink/fan could reduce temperatures all the way down to 50 from 66 at ultra heavy load. :S

Just FYI I've run a Scythe Mugen II on my PHII x2 555 BE at 4043MHz and idle was 33c while max load w/prime95 would max at 44c with single stock fan. Upgraded it with two Scythe Gentle Typhoon AP-15's and reduced temps to idle of 30c and max loaded temp of 38c.

Hey man, I've got the Phenom ii x2 550, which is almost the same, unlocked to 4 cores as well. I was not getting the worst idle temps like you, but when i ran prime on it, not OC'ed at all, i hit 60C in about 5 mins. I ended up finding a corsair H50 on sale at best buy for 60 bucks and figured I'd give it a shot. If you mount it properly, and put a push/pull configuration on it I think you'll see great results. It dropped my idle temps from like 35C down to 18C lol and I'm running Prime95 right now. At this moment, bout 15 minutes into the test I havent gone over 42C. I was having a bit of trouble with airflow in general, and decided to pop my hdd into my 5.25 bay so my intake fan wouldn't be blocked and it has done wonders for my system temps. Here is a before and after pic. You'd be amazed at what a good cooler can do for your temps. I'm pretty much blown away. Oh...This test that I'm at 42C max at is also with my CPU OC'ed to 3.6, so 400 mhz higher.



and after my HDD moved.





Take a little time and figure out how to get improved airflow and do some research on coolers and you should be all set.

Add mosfet cooling before any unlocking.

oh and soarky due to board issues you shouldn't be unlocking at all

There's a huge potential that your motherboard eventually blows up from the stress of a 125W+ overclocked processor, though it may take some time to happen. This is due to quality issues on that particular MSI motherboard. You should go back and lock those cores now.
