4870 Overclocking Thread

[ZOMGVTEK]

Just got my 4870 1GB in...
I modded the stock BIOS and I figgured 1200 would be enough on the RAM, but aparently not! Its stable at 865/1200 right now, i need to step the BIOS up a notch to get the ram at its limit! But the core cant go above 865, its stable for hours at 865, but locks up at 870 .

VMOD TIME!

I was thinking of messing with a softmod, but its probably just easier to hardmod.

Whats a good voltage for the stock cooler? Fan idles around 45%, load at 100%, i think the temps are 46 idle, 54 load. I changed the thermal paste and lapped the heatsink of course.
