Applying thermal paste

post #1 of 8
Thread Starter 
Hey guys, i was just wondering when i'm fitting the heatsink to my new opteron 146 how much thermal paste do i use? i was told to put a little dot in the middle of the cpu then put the heatsink on and it will spread evenly.

Also it seems i have a 512 stick of ddr400 and the other is a dodgy ddr333, would it be better to run jsut the 512 stick of ddr400 or run both of the sticks?

Thnx guys!

Place a small BB size amount of T/P on the cpu .Get an old credit card or the such and spread it over thinly making sure the cpu gets an even coat then replace the HSF

If you use both the sticks of ram the memory clock will be lowered to the slowest dimm which is 333mhz so i would only use the 400mhz stick if you plan to o/c .But another stick of 400 would be a good buy

If you are getting a retail boxed cpu with a fan then yes the paste will alresdy be aplied on the heatsink .but if your cpu comes OEM then you will have to get some ,most of us use Arctic Silver 5 it seem to be the best on the market at the moment

Or you could just let the h/s weight spread the paste

Why don't you just follow the instructions lol...

But if you want to know from someone who did it, then i would reccommend you squeeze out a BB sized drop in the middle, then take the heatsink and set it down on the proc until the paste mushes.

It may be different depending on thermal paste, but im pretty sure the retail version of processors come with instructions.

yeah, for your opteron you won't need to use a credit card to spread it out. the weight/pressure from the heatsink will do it for you. you're only supposed to use a credit card to spread the thermal paste out on small die or exposed die chips.

and yeah, if you got a retail boxed cpu there will be a square of thermal paste on the boxed heatsink. all you do is put it on and you're good to go. Although if you clean that up and use some arctic silver 5 you'll probably see a few degree difference.

and if you use both sticks of RAM they'll run at DDR333. I'd try both sticks out to see what kind of performance you get and then try just one. Personally I'd think it would be better to run both of them because even though they would be at a slower speed, you'd be able to run dual channel which would make up a tiny bit of the difference, and in my opinion 512mb of RAM just isn't enough nowadays.

It has been shown just lately that puting a bb sized amount of paste on the die then adding the heatsink is not a garunteed way of applying T/P .Go the credit card route it is mor succsesful;
