7950 For regular Overclock - Which one should i buy?

post #1 of 20
Thread Starter 
Hello to everyone,

Nice comunity you have here:thumb:

I am willing to upgrade my 570 for the 7950, i am thinking in 4 versions:

- GIGABYTE HD7950 Windforce x3

  • 305€
  • 2 Years warranty
  • AMD Never Settle bundle games
  • Quiet
  • Seems to be the greatest Overclocker

Major doubt, are the voltages locked for OC?no way to control them by MSI afterburner?


- PowerColor PCS+ HD7950

  • 305€
  • 2 Years warranty
  • AMD Never Settle bundle games
  • Seems to overlock very well

Major doubt, i dont really trust in the brand, experiences?


- XFX Double D Edition R7950

  • 305€
  • 2 Years warranty
  • AMD Never Settle bundle games
  • looks lovely
  • The PCB seems good.

Major doubt, seems to be hard to stabilize the OC.


- Sapphire HD7950 3GB Vapox-X

  • 293€
  • 1 Year Amazon Warrany
  • It has the 7970 PCB with improvements
  • Cooler is very nice

Major doubt, does it worth the lack of 1year warranty and losing the AMD games?

I am more willing to the GA or Powercolor.

Help needed please.

Many thanks smile.gif

The model i can buy is this one:

GV-R795WF3-3GD 900mhz OC, so i guess the new BIOS Boost to 1000mhz will work perfectly:)

yeah the gigabyte is the best card. also the F3 bios which was available till recently on gigabyte website has been removed. so you will have to get the BIOS from other Gigabyte HD 7950 OC users who have downloaded it.

http://www.gigabyte.com/products/product-page.aspx?pid=4121#bios

also the Gigabyte HD 7950 can mostly hit 1 Ghz at stock voltage. so try that first. if it runs stable stick with that. else you could go for voltage tweaking with sapphire trixx. manual voltage tweaking gives the best results in terms of choosing the optimum voltage to achieve desired clocks. thumb.gif

So i guess the GA is indeed the very best.

I thought the Sapphire Vapor with the 7970 PCB would be the best buy i was wrong.

Anyway, the order is made, GA incoming, i hope it OC´s very well.

Thanks

voltages arent locked with the gigabyte windforce, just throwing that out there (i actually own one of these cards)
post #9 of 20
windforce is the way to go. I have mine at 1200 and 55* game load.
