Topic: SAPPHIRE 100352-4L 7950 getting terrible speeds, 200-300kh/s. - page 2. (Read 6527 times)
I have the same reference card, secret is to go into MSI Afterburner and set power limit to +20, with that I now get 650 kH/s off each 7950 I have! and more stable too!
and more stable too! If you get Mhs, then you are not mining litecoin 
Sorry, it was a mistype. I'm using guiminer-scrypt, and i'm not quite that stupid.
I've updated my bios to the newest revision, and thanks to some of offbyone's settings, getting better hashrates, closer to 500 at unusable mouse party.
I honestly think 560 as my afk setting is about the best I'm going to do, though. Not sure how people are nailing 700+ but my temps spike up to 90 pretty fast even at the suggested settings. I'll post/update more but again, anyone else with the same card has settings or suggestions, please fire away.
(especially if you have a "I get 500kh/s and can still use that display to game" magical setting.... )
I'm not sure about previous versions of Asus GPU tweak, but the current beta version has ability to draw a manual fan curve which you can use to aggressively lower the temperature. With the case open, these cards run at about 76 C doing 575 kHs.
I don't consider gaming while mining. The ATI driver will crash if I even attempt to do that.
Are you setting powertune to +20? That's needed to turn "off" the power saving feature that will drop your clock speed now and then.
I have 3 of these cards and I get about 1400kh/s total using reaper. I could be getting more, but if I push my intensity higher than 15 I overheat. Once I get risers I will push them to their limit. Use reaper and try messing with your gpu thread concurrency. Mine is at 20480 i-15, I believe and I get a pretty decent hashrate

I've had nothing but grief tryin' to get guiminer-* to pump hashes. Scrypt, BTC, whatever. Doesn't matter. 60% hash rate.
CGMiner is great, Ufasoft's coin-miner is great, reaper is great. Reaper can actually outperform most of them but crashes more often. YMMV.

... or you got those FPGA that were rumored to be coming to work
.
My understanding is that you aren't going to be mining a scrypt-based coin at a decent rate AND have a useable system. If anything you've read disagrees with this, then please reference it for me.
550 kh/s is what I would the target hash rate for a stock GPU.

I have the same cards. bought it for 299 cad. look through my post history to get what you need. I used reaper, cgminer and guiminer scrypt. on we mine ltc .com or anywhere, I can comfortably now do 575 per card.

-g 2 at any intensity makes my system .1fps and drops my speed to 2-14khs. between 2khs. and 14khs. I have no idea why this card hates me so much.
I've got 6 of those cards doing 650. You need to bump intensity or try -g 2.

Is getting just the worst hashrates.I've tried the guiminer defaults, a bunch of stuff from https://github.com/litecoin-project/litecoin/wiki/Mining-hardware-comparison#wiki-ATI_AMD_GPUs
And a couple things I found on reddit, like http://www.reddit.com/r/litecoin/comments/1cbg51/my_7950s_are_at_800k_somehowprt_scr/
And I am just getting dick for speeds. the ones on reddit almost work: At least, on give-me-ltc it reported 650+ spike for a while, but my computer slogged to literally unusable, to the point where guiminer froze and I couldn't move the mouse enough to stop the goddamn miner.
Can someone post settings they are using with this exact card to get into the 600s?
