Default 4850 High Mem Temps?
My 4850's MEM temps are topping out at around 96c, today I took off the stock cooler and applied AS5 to the GPU core but I did not fiddle around with the memory or thermal pads.

My mem NEVER got that high, even with no heatsink on them, You've got something wrong there.

Crap, what could it be?

Should I remove the thermal pads from the stock heatsink ?

Well with stock cooler my memory temps were as high as 100C but with no cooler at all they top out at 70C and with ram sticks they are at 65C @ 1200Mhz. The Heat from the GPU heats the ram more then it cools them.

My non reference card doesn't even put ANYTHING on the memory chips, they're completely bare and my mem chips load at about 45 c! Albeit I can't overclock them any higher then 1025 mhz.

You can bet that the stock cooler is going to be replaced very soon...the moment I get $40 on hand.

You serious? you dont have good case cooling? well i did have 1 older 4850 with the single slot all cover heatsink, but the ram on it never ran above 80. But i did have a LOT of fans including 2 pci slot fans in there. But yea with nothing on the ram at all its much better.

EDIT, maybe you should try and find some non stock heatsinks for the gpu. Iv got 1 from my asus rev 2 that kept the gpu around 40C that i dont need anymore since i went water.

I am going to replace the stock cooler soon but meanwhile anything I can do to get my temps on the MEM down? GPU core temps are fine.
