Also anyone knows hit to fix overscan?

Oh yes, you can control the fan speeds for each GPU in MSI AB (I've tried up to 4 different GPUs in my old MSI 790FX-GD70 motherboard).

You can fix overscan via CCC, it is caused by using HDMI. You also can't avoid the overscan prior to the booting of WIndows, at least if you experience that.

Thx very much. +1
But for overscan, i have it on my monitor that is connected with DVI, but i also have TV connected at same time with HDMI.
For CCC, i just cant find that option.

It should be in the "My Digital Flat Panels" Tab, which used to be called Desktop Properites in the old CCC back in 2011.

So... 1.3v (GUI, since there is major vdroop under load) is safe to run on these 7970's as long as temps are good (Below 80ºC)?

I would try to find some heatsinks for your VRMs if you plan to run them at high temps. If the core is hovering around 80C, the VRMs tend to run at about 90~100C, which isn't good for the long-term lifespan of the card.

Question: What proportionaly overclocks higher, the 7959 or 7970?

I'm sitting here with my 7950 @ 1150mhz core and 1550mhz memory with 1218mv core+ 1625mv memory

Am I the only one here shattering the ghz barrier lol?
All I'm seeing is 1000-1050 mhz clocks.

My card also can past 1.1 GHz, but i left it on 1 GHz for everyday, i just love silent and cool GPU.

I think every card goes to 1100mhz core 7950/70, higher numbers are questionable tho.
post #13699 of 38704
I used Sapphire Trixx for the very first time for my HD7950


i changed the clock settings to 1000/1600
1. did i actually overclocked the GPU? (noobie) thats it?
2. should i expect after changing the settings?

VRM Temps are very reasonable for some reason on this Sapphire Dual X OC Edition 70. I have the profile set to run the fans at 100% at 60ºC since they aren't that loud @ 100% anyways. I'll do more checking with HWINFO on VRM's but the last time I ran them and the core was in the low 70ºC range the VRM's were in the 80's.
