Need help with 7950's.

post #1 of 8
Thread Starter 
I managed to sell my 7850's for $340 all up (Australia inflated), so I want to go for a single GPU solution. So much heat from those two 7850's, and quite hard to overclock.

I want to go with a 7950, as its the only card basically from AMD that isn't horribly price inflated.

So I need a 7950 that is voltage unlocked, and not too expensive.

I was looking at this:

Gigabyte 7950 3GB WF3 : http://www.mwave.com.au/product/sku-aa78414-gigabyte_radeon_hd_7950_oc_3gb_video_card

or this for a much better cooler:

http://ijk.com.au/branch/ijk/product_info.php?manufacturers_id=&products_id=138093&osCsid=091aae24d99b5458adefbdd4bcbb2798

What do you guys think? Are both of these voltage locked or anything?

Somewhere in Feb, I heard that there were complete Asus 7950 fails, because it doesn't touch the GPU properly. However that was in Feb, do you guys think this was fixed by now?

Thanks.

the sapphire HD 7950 950 mhz edition uses a HD 7970 PCB with 8 pin + 6 pin. manufacturer code 11196-10-40G

voltage unlocked with a good cooler. here is the card pics by user sonda5 running the card watercooled at 1.3 ghz. Hitting 1.15 - 1.2 ghz on air is quite easy.

if you want value for money you could also go for PCS+ HD 7950 boost with 900 mhz core and 950 mhz boost clocks . you can ask in the HD 7900 users thread about being voltage unlocked.

thanks! So does having the 7970 PCB have any advantages? Better cooling or better overclocking or something?

yeah better power delivery and more VRM phases . cooler running setup. better stability for extreme overclocking under water.

Good design. Good high quality VRM power delivery.

Great if you are are going to water cool because you can put any reference HD7970 water block on it.

Hmm, I love Sapphire cards (I had two of their 7850's), but what ticked me off the most is the blue PCB. I like the Powercolor card, it looks really solid and has a black PCB which I like. I can get a Powercolor PCS+ 7950 for $309, a 7950 Vapor-X for $325, a 7950 DCII for $339, and a 7950 950 MHZ, with the 7970 PCB, for $355. I'd be exceptionally happy with a 1.1 GHZ overclock.

Sonda, I noticed you were the thread maker of the 7950 revised thread. Are there any different 7950's now with 7970 PCB's now?

Thanks.

Nevermind! Their 950 MHZ edition with the 7970 PCB is Black/brown and that is great. Going to go for that once money enters my account.

Thanks all!
