I see another 20BTC since I last reconciled.  As soon as my next transaction clears, I'll send the 10BTC to match it.

Hmm I thought the first post said 100 BTC was the amount required ...

I believe 100 BTC at the time of the first post would have been around 650-660.  BTC/USD has dropped/fluctuated a bit since then...

Awesome awesome awesome  Shocked

As you may have seen I've done some preliminary work to the git tree since this collection started anyway so that cgminer will run at least satisfactorily on 7970 if not optimally just yet.

Thanks to everyone who donated  Grin

Thanks very much everyone. Arrived, shiny and all Cheesy

Took a lot of fluffing around to get it going thanks to AMD fail. Had to make sure the 7970 was in the first slot and manually edit xorg to make it work. The older driver detected the 6970s only and the newer experimental 79xx driver only detected the 7970. Then I did a little overclocking experimenting and found a nice sweetspot at 1200/1050 (it has a -150 gpu-memdiff limit).

See if you can spot the 7970  Wink

This is with an unmodified 2.2.3 with its defaults so that's what you can expect from cgminer at this stage at those clock speeds till I can wedge in a faster kernel.

Ck:  can you do the comparisons with the clock not set so high.  at 1200 they run pretty hot with a high fan, also if you just do down about 50 on the clock, you can reduce the voltage down to 1120 or so.

I am currently running   at volt: 1100  clock: 1100   650 Mhash diablo

Hmm I usually run my cards flat out, and I'm pretty sure the current cgminer kernel being 9 months old isn't going to remotely come near the diablo speeds but I can have a play... brb

I am currently running   at volt: 1100  clock: 1100   650 Mhash diablo

At your clock settings of 1100 (+5% powertune) I'm getting 638 Mhash. Voltage doesn't change on linux with ADL it seems.
Doing:
Code:
export GPU_USE_SYNC_OBJECTS=1
was mandatory for getting rid of the CPU usage bug. Interestingly with that feature enabled, there is an inflexion point in intensity when the CPU usage jumps up dramatically. With the cgminer default of 2 GPU threads, it is low CPU usage up to intensity 11. With 1 GPU thread, it is low CPU usage up to intensity 13. Both seem to provide only about 1MH difference.

And just for completeness, after the intensity investigation, I bumped it back up to the 1200/1050(+5%) clockspeed and put intensity up to 11 which seems the sweet spot. The final performance after it stabilised is:
Code:
GPU 0:  72.0C 4324RPM | 695.1/695.3Mh/s | A:98 R:1 HW:0 U: 9.79/m I:11

Looks like I will have to figure out how to get this thing working on linuxcoin...

I imagine it is something like

curl somespecialfile
edit xorg.conf directly

aticonfig initialize

?

See my post here:
https://bitcointalk.org/index.php?topic=28402.msg738468#msg738468

That has the basics.
Feel free to ask about anything else. After the effort you put into getting the funds together and card to me, you deserve all the software support you need. As does sveetsnelda for his excellent generosity and everyone else who donated.

Many thanks to ck the hard work and everyone else who donated!

I just changed over to 2.2.3 on my windows machine with two shiny new Sapphire 7970s and am getting 513 and 537 at stock stock speeds (running at a leisurely 78 degrees), a huge jump over 2.2.1.

Many thanks!

Excellent. Don't forget to use intensity 11 if you can.

I use dynamic on my main card and have been using 14 on the second as it's a Crossfire only card (I haven't progressed to the whole eyefinity 2 x 6 thang yet Tongue). I've changed to 11 and it seems to have basically the same rate. Coolness!

Working on the 7970 tuning, I have tried to port both the diapolo and diablo kernels to cgminer. Alas neither of them are actually working yet, so instead I started modifying the existing poclbm kernel in cgminer to improve throughput. This should work on other GPUs as well as the 7970, but I have no idea if it's better or worse than phatk.

When it's released it will get a new date/version number, but I haven't changed the number right now so that people can download it now and give it a try:
https://raw.github.com/ckolivas/cgminer/kernels/poclbm120203.cl

Remember to delete any .bin files and if you're not on a 7970 with the latest cgminer, you'll have to tell it to use that kernel with -k poclbm.

So what's the damage? Well on the 7970 at 1200/1050 clocks, which was getting 694MHash, it's now getting 711Mhash. The 7970 has this unusual behaviour where the hashrate slowly rises for the first 5-10 minutes.
