VGA RAM heatstinks.

post #1 of 21
Thread Starter 
I've got a Sapphire 6850.

I'm running it at stock volts OC'd

core clock to 925MHz

memory clock to 1100MHz ( I'd like to get it higher)

If I try to boost it over 1100, it artifacts.

I'm assuming the RAM is overheating.

Will the Enzotech BCC9 Low Profiled Forged Copper VGA Memory Heatsinks fit my card (Sapphire 6850)?

Thanks!

Your assuming the ram is overheating? How can you not know?

Yeah those sinks should be fine, chucked some arctic cooling ones on my 6870 today and am very impressed, just thermal tape ones aswell.

is there a way to check if the RAM is overheating?

I can't touch them, they are covered by the fan.

Its a serious issue in my opinion, none of you guys are watching your memory temps while you overclock. You should have Core, Memory, Shader, VReg temps up at all times.

I use Sapphire Trixx and in the Windows 7 gadget it monitors the following:

GPU Temperature
GPU Temp #1
GPU Temp #2
GPU Temp #3
VReg Temp
VReg Temp

Not sure what GPU Temp 1-3 measure?

Eyelegal, what software should I use to monitor all those temps?

Trixx sidebar is what i use as well, temp 1 is core, temp 2 is memory, temp 3 is shader core (feel free to correct me if thats wrong). Have that up on second screen 24/7.

GPU-Z also is good, but tends to make the core clock jump up to full load in random pulses as it accesses the card. Ideal for during gaming though, has an easy as pie logging feature so you can check what everything was getting to, and will update in the background on your second screen (if you have one) so you can keep realtime watch over temps while gaming.

GPU 1, 2 and 3 most likely are the Core, PCB and Memory.
Its not *really* overheating, but it is hot.

If thats load temps, ideal. Wouldnt be too far off my twin turbos performance.

If thats idle temps, not ideal, unless your in 30-40c weather thats getting high for idle.

@KROGOTH
Im pretty sure the pcb doesnt need a temperature sensor, as its silicone doing nothing. What would measuring that achieve? Temp 2 is definitely memory also. Made physical observations that putting better cooling on memory decreased temp 2.
I think temp 3 is shader, but im just going off what everest used to label them as. I trust everest.
