[Official] AMD Radeon HD 7950/7970/7990 Owners Thread - Page 124

post #1231 of 38704
Basically selling my old rig (and my current 5850) to get a 7970. Should have it by the end of the month *hopefully*.

I seen that the Gigabyte UD version was added to their site, I'll probably pick that (or if it arrives in time) the Twin Frozr MSi version.

I got my gigabyte 7970 today and opened it.
I looked at the 6 pin connector and it looks black?
I flashed with light and it looks grey now. How can I tell if mine has low vid or not?

Hopefully that holds true for mine. 1300MHz is what I'm shooting for as my minimum acceptable OC under water. upsidedwnsmiley.gif

Yep, nickel+acetal. Oddly enough, 1.175V @ 1160 core 1575V on air would artifact halfway into heaven and stay under 80*C but under water it ran flawlessly, same situations bumping to 1.2 and 1.3. From my testing it's very sensitive to the heat load, it's probably the determining factor for major overclocks (rather than all this talk about VID).

Even undervolting I was able to keep my card at stock (1.112v) and bump it to 1080 core under water (stable) but would almost immediately crash under air when loaded.

Good stuff! I figured water would change the picture, and it has. Can't wait to see more systems under water.

This whole grey power connector thing is bogus. I have a grey 8 pin and black 6 pin. Up to 1150 no extra voltage so fat. Unigine running for an hour so far, no artifacts.

Sooooo Vega... I was right. Waterblocks do make a difference with the 7970. wink.gif

My 4 blocks were stuck at the border... Sigh... Will get them only monday... rolleyes.gif
