Precision M4600 - Dual Core - 4 DIMM RAM???

i tried for the second time. I guess I will have to wait and see..

What else could i have done wrong?

 

Prime 95 is an absolute worst case scenario for you CPU. So if you hit 94 while using it, you can reasonably expect to never hit that while doing anything else.

The same can be said of FurMark with your GPU. You will never hit those temperatures during normal gaming.

This whole line of thinking needs to stop.

 

First of all, we are comparing an R3 with an R2. The R3 came native with a 6990. The R2 did not.

Brand of paste does not matter. Try a piece of cheese, you'll get the same results. If (matter 'X') will conduct heat, it will work.

I've already said this in one of the many other threads that you are spamming, the 5870 heatsink is not always a direct fit for the 6990 card that you're trying to make work. Please listen to me. PM me. Do something. The 6990 was NOT meant to work in the R2. There is more to it than pasting the GPU die and the VRAM. There are other components that require paste and pads on the 6xxx series cards.

Furthermore, if you are hanging up on the metal square around the GPU die, or the voltage regulators above the row of VRAM, that is a whole other problem.

 

yeah i understood that.

i just repasted my cpu and not sure if it is the AC5, but too often one core would have 10-12c difference than the other for a very brief time. The funny thing is that these two cores are adjacent.

like with real temp, it looks like this too often:

core 1: high core 2: low Core 3: high core 4: low

this pattern suggests that it is probably not the screws in the heatsink that has problem. Is it just cpu acting this way? this kind of happens to my desktop core2quad as well.

When idle, the temps of the four cores are literally all the time THE SAME.

I guess the temperature sensor is kind of off?

 

Hello,

I am not working with 6990s. I have 5870s on my R2. I just repasted the 5870s.

Cant afford the 6990s at the moment..

the previous replier was just sharing his experience with repasting his 6990.

 

How did you repaste your CPU? Did you do the thing where you put the blob of compound on the CPU die? I'm sorry, but I don't care what others say, that is not the way to do it. Put some thermal paste on the die and spread it with whatever you want. A glove, a sandwich bag, a cucumber, your bare finger, it is all the same. It is all splitting hairs. All we care about is full coverage. Spread the thermal paste on the damn die and let the heatsink determine how it is spread. I've seen the video where the air bubbles occur, and I'm saying that it is B.S. We have exposed cores where the 'blob' method is not applicable. Get an even and thin coat on the core and put the heatsink on by tightening in even increments. That is all you need to do.

 

OK. I apologize then. If you're using some sort of thermal compound on the die (shiny part), and .5mm thermal pad on the VRAM, there should be no issues.

Fan and heatsink fins need to be clean too.

The little screws won't let you over/under tighten the heatsink.

 

yeah ok I will try that then. Im sure this cpu is great but not sure why the temp sensor is playing funny. although I have repasted i7s before and the OVAL blob in the middle seemed to be able to cover 100% of the surface.

do you think that coverage will help get rid of this wierd differences of temperature ?

Thanks again for your reply

Edit: Actually, I think the temperature sensor might be bad. in one second, second core temp is at 62, and LITERALLY the NEXT second, it will shoot up to 82c and literally the next second later, it will go down to around 62 again. This repeats a couple times although there is consistent usage in that core.

i am not sure how there can be 20c difference in a matter of split second.....

 

i am going to see if it settles the temperature and if not, i will replace this stock dell pad on the vram with the 0.5mm pad from frozencpu.com

 

Like the other thread says, if you're using some type of thermal interface material (TIM), you should be fine. It could be toothpaste.

There are other variables though. Thermal pads should be .5mm thick. If you use anything thinner or thicker, you are disrupting other heat exchanges.
