If I was buying more now I'd have no qualms about 7950s but I would get the Gigabyte cards for the better coolers.

RTFP, not the model we're talking about.

2L is better than the gigabyte. Ignorant mofo.

I have 2x Sapphire 100352-4Ls

They are very loud and they run hot. They do overclock well, I've had them up to 1250 for short periods but normally run at 1000 for better temperatures. About 520MH/s each at that speed.

P.S. They are not voltage locked, which I found odd.

Best would be dependent on the user's tolerance for noise, heat, undervolting, overclocking options.

Personally I prefer ref cards since I just lock my cards away at work Grin

I have an 6970 HIS stock cooler on it and it's warmer and louder then my 2 Gigabyte 3 fans 6970 even if the HIS is unlocked and undervolted.

go with the 3 fans Gigabyte and open case or lots of fans over a stock cooler even if undervoled. Grin

but that's not with 7950 Roll Eyes

So I happened to pickup a couple of the gigabyte cards - imo the custom cooling in junky. The cards vent heat in all directions and in addition to that the back side of these boards become quite hot. No chance of running these on board without it overheating whatever's behind it.

IMO the ref. design with the canister is much better since it vents out the back of the case.
HIS-iceQ or Sapphire Vapor-X are the best options imo.

I have several rigs now and have been undervolting and whatnot with no real guidance. Can anyone point me to a good guide or to a good thread about undervolting (7950s and one 7990 are the majority of my setups.) I have looked, just haven't found anything other than stats about what people have cards at. I am looking for the underlying methodology on it and heat in general. Though I have several systems setup now I know my heat profile for these systems is only 10% above n00b level. Thanks,

The gigabyte windforce is basically the best 7950 around.

Pro's
Reliable
Cool
Quiet
Can get high stable hashrate.

Cons:
Huge
Heat expelled everywhere(Filling a closed case with hot air)
Voltage Locked(if you start having trouble with heat in summer for example it nice to be able to undervolt the cards to keep them cooler)

The XFX has no advantages over the gigabyte so just ignore that one.

I personally would get the Gigabyte but not being able to undervolt is a concern, i know i will be undervolting my cards when the summer temps begin to ride.
I recently bought a powercolor AX7950 3GBD5-2DHV5E and i am very happy as it is almost as good as a gigabyte windforce but was cheaper and is not voltage locked. Availability might be poor though Tongue

Part of the reason I bought two sapphires was because of the rebate, but unfortunately it's limited to one rebate per household. Keep that in mind if you're buying more than one card.

Newegg has the SAPPHIRE 100352-4L 7950 for $270 with 3 free games. Worth it?

Well all of those cards, on Newegg and on Amazon, all comes with those games.
But its 290 + tax .... the Mail-in Rebate is 20 dollars back, but those suck lol

But yeah that's why I keep asking which card is better overall (quiet, cooling, Khasing, overclocking) cause Im down to this one and the Gigabyte which is only like 10-15 dollars more, for a better card I am willing to pay more money. The guy who said eh has like 7 Gigabyte cards, I think you've won me over. Straight outta the box clocking really nets that great of a hash rate? I hope so cause you cant change the voltage I heard Sad

Ah ok. I noticed that card on the Newegg home page as a daily deal, so didn't know if the price or the games were special. Both look to be pretty common, so idk why it was advertised?

The Sapphire is $270, and the Gigabyte is $310. I love Gigabyte, but is $40 worth it? Also, what are the VRM temps on the Gigabyte? I have the Gigabyte 7970 GHz edition, and it has a heatsink on the VRM chips, but they still run hot. The stock cooler directly cools the VRM chips, but the aftermarket Giga one doesn't.

If the Sapphire one has a stock heatsink, and gets good hashrates, I'd say go with that one.

So the 4L or the Gigabyte?

Which is the better choice? and Pros and Cons of each?

Someone said the Gigabyte with the 3 fans was voltage locked, is this true?
But then everyone else says the 4L runs way hotter than the Gigabyte and is a loud son of a bitch.... Consensus?

Sapphires are loud (duh, REF always are), but I get 575 Mh/s @ 1100/300 70-72 C with 65% fan on BFGminer. So I'm pleased with them currently. If noise is an issue, then go Gigabyte. Oh yeah, I'm 1.050 V too.

Sorry, I missed the Litecoin application.

I have 2 Sapphire 4Ls and 7 Gigabyte 7950s. In my opinion, the Gigabytes are much better cards.

The Gigabytes come factory overclocked at 1000/1250 and can do over 600k mining litecoin with no extra overclocking or overvolting.

The 4Ls run hotter, have extremely loud fans, and don't perform very well. I can only get the 4Ls up to 550k mining litecoin overclocked to 1000/1250 with overvolting, which puzzles me. I have no idea why these cards don't seem to perform as well as the Gigabytes at the same clock speed, but the Sappires do like to throttle back a lot.

Needless to say, I have 4 more Gigabyte 7950s on the way and won't be purchasing anymore Sapphire cards.

Very good info everyone, thank you so much!

+2. Running 3 of them at 1ghz core at 1000mv vcore. They are loud like any reference design squirrel fan, but they run cool. Also, not voltage locked unlike the latest batches of the Gigabyte 3 fan card. XFX card is absolute crap. Belongs in a "Worst 7950 card right now" thread. I can not speak to the PowerColor.

I as well have 3 4Ls currently, yet I'm still having a bit of trouble getting them dialed in..
I have powertune to +20 and clocks to 1000/1250. (cant tell if that's best...)

My CGMiner is the main thing giving me trouble.... anyone care to copy/paste an ideal input??

edit:: I found this thread quite helpful. will test tomorrow https://forum.litecoin.net/index.php/topic,620.0.html
