Hd4850 Issue

[Lauralarry]

I've been away from home at my girlfriends house for about 2 days now I meant to post this earlier.

I asked my girlfriend about the HD4850 I gave her, I had 2 in crossfire (She plays League of Legends only). She told me she noticed that over time her FPS starts degrading and it would usually start off at 70 then drop to 25 - 15(Medium) so this is a over time type of thing, So I downloaded MSI Afterburner and lowered the Memory clock and it stays 25-40fps (medium) she says it's playable now at 700/700Mhz Core / 700/1200mhz Memory. But I really don't understand why.. in my rig they were fine

The gpu isn't over heating..

the fans on 100%

it's 70 fps for like 20 minutes then craps out to 15fps

What power supply does she have?

Hmm I thought it might be a psu issue, have you tried it in your pc to test if it is actually a problem with the card

whats the cpu like though temps?

first though was dry paste, the overtime fps would work, also you lowered the clock so that would also fit but you said its not overheating(exact temps?)

Sounds like was running out of VRAM (most likely), DRAM (second) or L2 cache isn't beefy enough.

in her case it runs 38c idle 52c max

Yeah I think she needs new thermal paste, and she has a pentium D they're the hottest Intel Cpu's ever made :/ 130W crappy architecture

FIXED! it was the cpu thermal paste
