okokok... On Sunday amazon had quite a few of the twin frozr III's and I bought 2 (should have done all 3 for this rig). Taco - Awesome write up - but I have to wonder if this post helped caused the shortage of these cards and drove the price up on ebay to over 900$ lol those reaper settings are spot on btw.. I'm pulling a little over 600kh a card running them stock in a dual card rig. Def a good recommendation on them. Thanks! Amazing gpus I'll tip you some of their mined LTC I'm going to try out the 7970's from this line on another rig I think. Have you used those?

The grue lurks in the darkest places of the earth. Its favorite diet is adventurers, but its insatiable appetite is tempered by its fear of light. No grue has ever been seen by the light of day, and few have survived its fearsome jaws to tell the tale.

The BIG problem with trix is that it doesn't save the power settings when you restart your system. That means you can't autorestart the system once in a while without babysitting it. Also.... why are you tryingto stay out here ? I really enjoy your posts. Please, also give us an update about your VERY interesting MC2 concept !

I will lose my job (and $25,000 for the remainder of the year) if I don't pass my exams that are coming up this week and the following week, so I need to complete them first MC2 update coming soon, tons of things will be changed (new PoS strategy, more optimized hashing algorithm) based on the feedback I have received.

Umm I have 3x 7950 and 1x 6950 on this rig.. When I use cgminer, it gives me the error: "Error -5: Enqueueing kernel onto command queue. (clEnqueu eNDRangeKernel)" on 3 out of the 4 cards. This usually happened to me when I didn't export the variables needed by cgminer, but nothing yet. I have 10 GB RAM on this, do I need more?

How much does the build quality vary on 7950s? Wondering whether I should get an XFX HD7950 or get more of the Saphire 7950 (The Saphire costs about £50 more, that about $75).

I'd also like to use the rig for some computing. Thinking of getting an i7-3970k with 64GB of RAM. Should I get a bigger power supply for them?

I have two 7950s and I am able to get between 550-600 kH/s using GuiMiner-scrypt's default 7950 settings. Usually, it is around 560 kH/s. Once it was running stable at 605 kH/s but that was the first time I used it and haven't seen that consistently since, even though I think I am using the same settings.
You have to imagine that many of these stories about higher than normal hash rates are just that - that is how message boards are, there are always those Keyboard commandos that can do the most amazing feats.

Attempted to use your settings but Reaper won't connect to my pool.

If it's stratum you must use the mining proxy (see sig threads)

both XFX and gigabyte cards, brand doesn't seem to make any difference as both hash at exactly same rate

I did have slightly better luck with reaper vs cgminer, however I could not figure out how to setup a backup pool with reaper. That alone is worth the few kh/s loss in switching to cgminer.

After trying the mining proxy, my display GPU which isn't even being used to mine crashed completely. I reset and now none of my miners work. Not Guiminer-scrypt (CG), reaper, Guiminer, etc. And the display gpu crashes constantly.
