HD 7950 Memory Overclock

[xTommy92]

Hi Guys,

I have just finished overclocking my Core Clock sitting at 1250Mhz @1.3v and have just started overclocking the Memory. The only problem I am having is that everytime I run Valley I keep getting white dots appearing on the screen and no matter how many times I keep adding voltage the white dots keep haunting me?!?

I am currently on 1355Mhz @1.638v with the Memory and I still keep getting them.

I was reading about 7950/7970 overclocking recently and overclocking the memory didn't have anywhere near as much affect on performance as overclocking the GPU itself in the benchmarks I looked at. Ram is one of the common things to break in graphics cards too so I would be careful pumping extra volts into it.

White dots means your core clock is struggling. I'd suggest lowering the core clock until the sparklies vanish.

Does 1.3v sound okay to you on the core as I am only getting upto 80 Degress max?
Also when you mean break in, do you mean actually break the card or RAM does what the memory does?

yeah memory almost pointless clocking from what i read

Thankyou Matt, I will have a go at lowering by 25Mhz. Cannot go any higher on the voltage as I am already at the max.

1200 is normally the sweetspot Tommy. I'd aim for that and take it from there. At 1200 you might be able to lower the voltage a bit maybe and bring temps down. Unless you're on water in which case ignore.

Cheers Matt, lowered the Core to 1200Mhz @1.250v and is reaching 70 Degress max. Also thankyou for your help in my previous thread with the overheating problems, i have sorted it. I re-applyed thermal paste to the heatsink, whoever did it previous to me had used a whole bloody tube on the thing, it was a right mess!

Cleaned it all up and re-applyed with a grain of rice size blob, lowered my temperatures a gooden!

Good stuff Tommy.
