Guys.. i need to decide between 7970 and 7950.

Going to get 12 of them to mine Scrypt coins..

Just can't decide which brand and model to get.

Opinions ?

gigabyte 7950 !

Which one you got ?(specific model)
How are them performing on scrypt mining ?(hash)

buy a couple to test first? what are your options?

I went for 4x Giga-byte 7970 "TO" (1050 core, 6000 RAM) to test, as it might be possible to push them up to 750-800 KH/s. I'll break even in 4 months at 600KH/s (expensive rig), probably faster if difficulty spikes (less LTC but if BTC history serves, LTC/USD should also spike).

The "TO" core have "Boost" (up to 1100) which I don't like (will try to disable it) to keep a certain ratio between core and RAM fequency. I went with this one for the faster memory (6000 instead of 5500), hoping the better quality memory will be able to OC better if I need to push the core clock. (I don't think heat will be an issue, it'll be in a datacenter with a bunch of fans on it directly)

I'll probably make smaller rigs too, to max out my amps allocation per rack, probably looking for cheaper cards then (possibly even lower than 7950).

This might be of help:

I was about to get XFX FX797GTDFC which has the same 1050gpu/6000ram. But I've read a bad review about XFX FX797GTDFC temperature.. so I'm not really sure which one to get. Did you get your 7970 already or still waiting for it ? Would be nice to know if those 7970 can make 750kh/s... if not, then ill probably choose 7950.

Ive got 2x 6990 hashing 850kh/s each and 2x 5970 hashing 650kh/s each...

Where did you ordered those 7970 ?

i'm confused.
so RADEON makes the GPUS and the other companies provide the enclosures and fans and ram?
sorry - super newb

No, AMD (formerly ATI) make the GPU. They sell the chips to MSI, Asus, Wang-tang China Industries, whoever, who solder the chip to a board. It might be a board designed by AMD (IE a reference design), or some others like Asus design their own boards.

The MSI one looks like a reference design, as it has the old hair-drier fan design which is effective but loud.

out of that list sapp and MSI TF are the best. for OC it's same as lottery. Your chip may not oc or do very well.
I have a MSI card running that can do over 1200 on core stable with small v bump mining btc and ltc. getting 640 kh on ltc atm.
air cooled, and doesn't go over 80C

With intensity 20 don't you get some HW errors?

So from what i've read MSI hit 600+ easely...I thought about sapphires but MSI (also heard that HIS can hit 630KH) seams the way to go.

I just built a rig with 3x XFX 7950's and I concur with hem sucking... i have to push them pretty far on the OC to get ~520 ea and they run hot with the alum surrounding the heatsync. My MSI 7870's hit 475 w/ barely overclocking and eve an HIS 7950 gets 550.

GIGABYTE GV-R795WF3-3GD - cool, quiet, mining ~602 mh/s

Aren't those voltage-locked?

https://forum.litecoin.net/index.php/topic,2641.0.html

yup they are, but still are able to get ~600-603 mh/s, stable 65C ~70% fan, milk crate rig so there is plenty of air to flow.

I wouldn't get XFX, supposedly lots of problems. Id recommend the MSI as well.

I mounted it today and I'm getting barely 490 KH/s :| Help, thats not fair

So what? If they're cool, quiet, and pull good numbers, why do you want it unlocked?

I love the sapphires - esp for in case designs. Great fans, voltage unlocked, great to OC. Running 3 right now @1700 mh/s total just under 650W for the cards. Temps in closed case ~70C.

Oops, that's khps for litecoin.
