post #27251 of 38689
For those of you that have done that "H50 mod" to your 7950's, how do you keep the memory and VRM's cool? My last experience mounting an Accelero kind of left my 7970 dead thanks to the heatsinks falling off. Plus I'm not sure where I can buy those heatsinks.

Hey my XFX 7950 overclocks like ass - 950 on core and 1500 mhz on memory. Any way to improve it? Not sure I want to mount a custom cooler...

A better cooler would only help if your card is running too hot.

Many XFX cards just don't overclock well, so unless temperature is the problem, there's not much you can do.

Maybe try some a different BIOS or something, but those are hit or miss.

For my vrms I used enzotech mc01 heatsinks needed 2 packs and for the ram enzotech mc10 heatsinks need 2 packs as the rest can be usdd on the othed lil chips.
I havenet mooded mine yet but ive put sinks on the vrms n just let them settle for an hour not fell off yet. I left tge shroud off thinking airflow would be better but im putting it back on as it isnt

I used some seskui #5760 to hold the stock heatsyncs on.. I'm going to get some copper ones one day and re-mount them as the VRM ones aren't on very well. (Thermal tape on each side of the thermal pad) - As the capacitors stick up too high and the VRM's have bad contact if I don't use the thermal pad.

To overclock more obviously? I never had any temp issues at 1.3V on my Vapor-X card, could have easily pushed it higher.

Search for the 7950 BIOS mod thread, upload your BIOS and he will unlock it all for you using HEX codes etc

i will look into it, was going try the msi bioses on techpower up, when i put it underload the core drops to 63 to 100 and speeds fluctuate to 830 840 and lower


you would think that cards would come with stock bios on one switch and a boost bios on the other no mine came with boost on both, the stock speed was 830 boost is 840 1.25v for 840 is rediculous
