Yea running at 4.6 stable must really suck.......:shadedshui am 3dmark stable at 955 core at 1.45vgpu @ 62c load, as long as your volt regs/ram is sufficiently cooled, i see no reason why you cannot get those speeds, no reason at all.
yeah, the full coverage is a drawback in that sense, I was quite tempted by crossfire 3870's. but meh, I lub my card , and i doubt id get anywhere near what i paid for the card + waterblock. damn this habit is expensive.....
however dx10 is a bit more picky, I cant run much above 900 in dx10 without small artifacts, but that was only tested with the bios's 1.35v, maybe more vgpu would help.
my ram voltage is veried atm, still trying to work out what the hell it likes. I have ran 1200 on my other cpu @ 1.4volts, been running around 1.35ish atm just to make sure that theres no instability. 4.6GHz at that fsb is dissapointing tho, i just cant seem to get a high fsb without crashes, im sure im doing something wrong... AMD overclocking was SOOOOO much easier
O I wish i could hit 4.6
For the HD
I found that 1.25 was better on AIR at 900Mhz. I still had artifacts, but less of them. I seen some of the highest OC bios have lower volts.
Have you tried 1.25-1.30v yet with your card?
