Leo has a board with a hacked BIOS which allows for overclocking thus the reason they are at 2.7GHz, which is insane on so many levels given the hardware.
I think I just poo'd my pants... Wowzers!
Question, what Ubuntu optimizations can be done?
Production. The beast turned out to be as powerful as I had hoped. Project P6903 typically runs at a rate of around 17:00 to 17:05 minutes per frame (TPF), which, at today's bonus rate (QRB), equates to about 370-375K PPD. The P6904 should be better, but I have not been fortunate enough to download one yet.
In preparation for this build, I sold off a boatload of GTS 450 video cards that I previously had Folding. (If you missed my sale at Icrontic's http://icrontic.com/categories/buy-sell-trade, hey, what can I say? Go on over there and take a look!) Our home power bill now is about $100/month less than what it was one year ago, even though we are having a colder than average winter. The AMD 2P and 4P rigs are a tremendous bang for the buck in production and power efficiency. On the efficiency scale, nothing comes close.
* PPD: best so far is 375K PPD
* power draw (no one asked, but should have): about 600W, full load
* Ubuntu optimizations (Tushon is hot on this as well): 1) "Langouste," which is an automated background app that uploads completed Folding work units simultaneously as new ones download, 2) "The Kraken," which is a load balancer, that keeps all the CPU cores sharing the Folding load as far as possible - scaling is excellent, 3) and a couple scripts that allow Linux to engage the overclocking settings (please don't ask how it works - it just does!)
* CPUs (_K_ was correct): 4 times AMD Opteron (Magny Cours), each 8 physical cores, default 2.4GHz, overclocked 12.5% to 2.7GHz (NOTE -- The RAM must also be flashed, otherwise the factory JDEC settings will not be sufficient for motherboard's custom BIOS.)
On a personal note, Team 93 comrades, I fully understand that we've all got different levels of enthusiasm and different budgets. It took me over 10 years (yes over 10 years) of Folding before I had the resources to put together a rig like this. I'm past the age where 'impressing' people is important for me (hmm, unless a promotion can be earned...). My intent with this thread is to inspire you Folders to bigger and greater things - it doesn't have to be the top. Just one PPD improvement is still improvement. Another reason for posting this thread was simply to share with you. This project has probably been the most satisfying computer hardware endeavor I've had since I accomplished my first home-built computer in 1998.
Actually, time Folding and time as an Apu's/Icrontic member are pretty close.
TPF average: 23:12
PPD: 388K

That was my reaction as well, when a few months ago I started seeing Folders experimenting with Intel/EVGA SR2 and AMD G34 rigs. "No way!" Yes, way!
_k_ has a couple of angry dragons as well - A Supermicro (Tyan?) 2P G34 and an Asus 2P G34.
I am folding for the hardware.no team 37651, as -alias-
This is my new G34 rig that I built recently. The case had to be modified a little, and so had the CPU coolers, but all together it works fine and are very silent, and in my opinion it looks not bad either.
- Xigmatek Elysium case
- Tyan S8812 Motherboard
- 4 x Opteron 6272 CPU
- Antec Kühler H2O 620
- 64Gb Corsair 1600MHz RAM
- Chieftec BPS-950C 80 PLUS Silver
- OCZ 2.5 "Flash Disc / SSD 60GB Agility
Not as much as you might think.
For P6904 349K PPD. It is about the same or better PPD for 6903 with 352K, and 280K for the 6901.
Opteron 6272 have only 8 x FPU, so we're talking 32-core for folding even if the rig has 64 cores. Power consumption from the wall is, however, only 550watt and I'm happy with that. All together I have 8 rigs going 24/7, but I'm about to replace the 2600k (4) and 980X (2) rigs. Most likely I will replace the 6 with one 48P G34 rig.
