Back to AMD

post #1 of 8
Thread Starter 
I haven't owned an ATI/AMD GPU in over a decade, but after I destroyed my GTX 670 (not intentionally) I decided to finally go back. I just bought a Sapphire Radeon Vapor-X HD 7970 GHz OC and I'm pretty impressed.

I used driver sweeper to wipe out all my NVIDIA drivers, installed the AMD drivers, and updated. No problems at all. I'm glad I ignored the stories about how GPU's "exploding" due to AMD drivers.

In any case, I downloaded MSI Afterburner, set the clock speed to 1200 and memory to 1600 and just gamed for about 3 hours with no problems. I didn't touch the power limit or voltage.

I had to remove my entire water cooling setup, so this sucker will be on air. Max during gaming was about 61C. I'm not sure what this GPU's limits are or if I should even bother touching the power limit or vcore. Does anyone have an idea and/or what are generally stable OC's for this version of the HD7970? I know YMMV, but in general, any ideas would be helpful.

1200/1600 on stock voltage is pretty impressive. You can bump the voltage, bump the power target to +20, monitor temperature and check for stability. You could probably reach higher clocks. (1250mhz - 1700 mhz) or even ( 1300mhz / 1750mhz) ishh

You can also raise Memory voltage up to 1.7v for better memory clock, if temperature permits it.

Hmm, I may give it a go. I'm waiting to re-download BF3/Crysis 3 now to see where I'm at and if it's even necessary. I just finished my 3DMark runs and Heaven runs and all is stable. Big fan of this card.

Got XFX dd 7970 ghz in 1300/1650 ...So vapor should do the same..but if no bencmarking I c no reason. Single 7970 plays all games in ultra and eyefinity thumb.gif (aaa 2x in some games..with CFX 8x aaa too)

Vapor-X seems nice... Havent tested.

Got 7970 ghz dd xfx and Asus Matrix HD 7970 wich impressed me actually smile.gif

Yeah, I actually was just looking around on Amazon and saw a price drop to $369.99 for this card. I had a good amount of Amex points, so I figured it was a steal. I can't believe the GhZ editions, and the vapor-x at that, are below $375.00. I'm guessing it has something to do with the GTX770.

So I just noticed the boost button wasn't pushed in, so I went ahead and pushed it. Is this going to do anything to my OC?

when you manually overclock it does not matter. also make sure to max out power control to +20% to avoid clock throttling.

Do it manually from BIOS. Auto oc is..autooc.. OC is always a gamble so imo rather do it manually.

Plenty of oc guides in OCN. Would help my-self but Intel chips...got no experience except raw text fact. No own experiments with i3,i5,i7's

Because of the chip pricing went full amd myself.
