Want legit 7970 testing/benchmarking and tuning for cgminer and Diablominer?

[teek]

OP - How about a virtual contribution?  I have a 7970.. just got it today..  I might be willing to give you a linux box with full root access with 1 7970 installed for optimization purposes..  Is this something you would / have considered?

that's a good idea!

BREAKING NEWS: I now have all the donations needed to grab that 7970, I should be ordering it within the next week give or take.

The last donation was big enough to help me cover that gap, and I think this wonderful person wishes to remain anonymous due to the size of the donation.

Sweet! Looking forward to what GCN can achieve

I'm pretty sure Diablo has put hundreds of hours into his mining code that most people use without giving him anything.  If you consider a person's time free, then yeah... I guess it's free.  If you are at all intelligent though, you would realize Diablo is someone who deserves donations.

Great, I look forward to a new kernel for cgminer... though I expect I'll end up doing that myself based on your work

Spend hundreds of unpaid hours messing with internals of GPU programming (I guess at this point DiabloD3 knows parts of the ATI hardware better than the AMD engineers). Write one of the most used miners and a mining core that's used in other very popular miners as well. Also be supportive of it - answer questions, test bugs, do fixes and continue improving it until you squeeze another 1% performance, and another 1%, and another 1%. All this makes money for the miners using it and you're not getting paid.

Then you will get "free" stuff.

No one pays ME in gum
 
Looking forward to see what you come up with Diablo

Not better than the engineers, not even close. The problem is, theres stuff that just isn't documented on how Radeons work, and most of what I know is either ArtForz or I threw shit at the Radeon to see what would stick, and then mixed in some moon dust from there.

The GCN, though? Lemons.

I wish I had stuck with assembly programming.. I totally rocked assembler on my Apple ][e 
 
But alas, life took me a different direction.. I'm thinking had I stuck with it, I could be squeezing some more performance out of a miner by redoing it in assembly.

The CPU miners are written heavily in assembly in some areas just to get maximum speed.

You should take a look on this results: https://bitcointalk.org/index.php?topic=57410.0

They are really impressive and there will be an improvement on scripts and everything.

A photo of 3 7970s in their naked and shiny glory? Let me save that to my porn folder....

This(!):

Three 7970's:

System Idle: 290 watts
Mining: 925/1375mhz, 1.17v, 630 watts
Mining: 925/340mhz, 1.17v, 625 watts
Mining: 925/340mhz, 880mv, 360 watts
Mining: 925/340mhz, 865mv, 345 watts

~1650mh/s

Single 7970:
System Idle: 290 watts
Mining: 925/1375mhz, 1.17v, 210 watts
Mining: 925/340mhz, 1.17v, 208 watts
Mining: 925/340mhz, 880mv, 120 watts
Mining: 925/340mhz, 865mv, 115 watts

550mh/s

Efficiency-wise, it's awesome!  But $1/MH sucks

Agreed. There are better mining solutions out there. No one will be swarming to get 7970s for mining unless someone pulls a rabbit out of that GCN architecture.

I recommend you guys click the link to my thread and not rely on the quoted info from it as I keep updating the results.

Curious about how much room for optimization there is, I made some calculations to see how close Diablominer is to the maximum theoretical performance of the 7970 (see here) and unless I'm missing something in my assumptions I found it to already be within ~2% of the maximum theoretical performance.

Edit: Fixed link.
