i figured out the problem with Sapphire 7950 4L model cards not getting above 600kh/s. Make sure the power limit (either in CCC or in Afterburner) is at +20%. As soon as you move that to 20% and use some known good settings and clocks you'll be all set. I'm now running ~650kh/s per card. Hope this helps a few people.

Balthazar: Me: Posted my reaper kernel here: https://bitcointalk.org/index.php?topic=117221.msg1834570#msg1834570 what brand and model card are you using?? I've tried a ton of combinations and i seem to get best khs from stock clocks. I'm using the sapphire 4L

As such they should all also have voltage control. Once these go out of stock they will likely not be replaced, so grab them while they're still around. edit: voltage control confirmed with sapphire trixx http://www.overclock.net/t/1378557/sapphire-100352-4l-and-21196-00-20ghd-7950-the-final-holy-grail-of-hd7950s ok so i picked up 3 of the 7950 4L models for my 2nd rig. I can't get these suckers to go past ~530kh/s i've tried a ton of different settings and configurations with no go. Anyone have any luck getting 600kh/s+ on these?? Per my post earlier. I have these same cards and can get a max of 530kh/s. If you find any settings that can get you up to 600, let me know!!! Yea i'm kinda pissed. i was expecting to get AT LEAST 600 out of these

yea i know. i have 2 rigs (7 cards) setup but mining LTC right now. I'm part of this pool with my little 6850 just takes forever.

on: April 10, 2013, 01:31:45 PM

i was going to setup solo mining but not sure if that'd be worth it either. I was just looking to make a couple coins in a new currency and see how things go.

on: April 10, 2013, 12:52:14 PM

so i pointed my least powerful card here to see how things would go (260mh/s) but man it takes a while to find a block. if i'm pushing that much (not a lot) and the whole pool is only 800-900mh/s i guess everyone else is cpu mining?

My setup: 2 - 6950 1 - 6970 1 - 6850 3 - i7 2600 I'm mining LTC ATM so i'm getting about 1.8mh/s

Been mining for a little over 2 months and new to this forum. Mining LTC at the moment and doing as much research as possible.
