Related to the topic beginning, i have a wide range of (more nvidia) cards ready for wcg. From 8800gt, some 9800gtx, 295gtx, 560ti, hd3850, hd 4870, hd4350 and so on...Ready to invest something in a new cluster with xx cpus and some gpus :)

Was attempting to setup a dual-boot ubuntu/W7 (unsuccessful) last night, and after i cleared my cache, I decided to see if the newest 7.x Boinc version had yet solved the NVIDIA problem of incorrectly detecting GPU FLOPS, figured I'd post this, just because I found it interesting. (Don't plan on keeping it if any problems arise)

4/8/2012 12:20:42 AM | | NVIDIA GPU 0: GeForce GTX 680 (driver version 301.10, CUDA version 4.20, compute capability 3.0, 2048MB, 1924MB available, 2167 GFLOPS peak)
4/8/2012 12:20:42 AM | | OpenCL: NVIDIA GPU 0: GeForce GTX 680 (driver version 301.10, device version OpenCL 1.1 CUDA, 2048MB, 1924MB available)

Apparently, the newest BOINC states whether or not the GPU is OpenCl compatible, as well as amount of AVAILABLE vram, and not just the amount that the card is said to have. The Gflops still seem off, they too were complaining about how NVIDIA does not provide API, which leaves them trying to figure out the math of the new Kepler series (i guess?). This was on BOINC 7.0.25 Originally (6.10.58), BOINC was posting Gflops rating as 361 Gflops. Apparently since the the clock can jump around so much due to the power management features, (starts at around 705, and as I'm typing this it's at 324)

Just though it was intersting, and somewhat "upset", that basically the few projects I participate in do not have apps out to support these new cards. Waiting "somewhat" patiently And the ones that would/could support it, Einstein I believe, are blocking cards with driver 295+ due to monitor suspend bugs.

Just discovered a SERIOUS problem with these cards. Despite fact they weren't designed for crunching. These cards DO NOT obey voltage limits/floors. The boost technology takes what it wants when it wants. Mine is EVGA, and problem is on all cards though. On fermi, if you set .975 it stays there (i know there's no boost though). When my gpu enters boost, which it will technically always be in unless card gets hot while crunching, the.voltage stays at 1.175. It takes what it needs whether u like it or not. As of right now I'm attempting negative offset with precision, but so far.no luck.

According to his earlier post yes he is using that one.

It's.apparently the way it was designed. There's posts on NVIDIA forums about how big of a problem this is for an enthusiast board. Thought about it though, and as fat as I can figure since I'm not.the one who overvolting it, its under warranty then. So for anyone thinking about getting one I recommend EVGA or ASUS because of their customer service and EVGA. For their good warranty. And as far as amd is concerned I just look at their wiki page at flops performance/watts to decide. They are definitely gonna be better for this project.

Happy Easter to everyone.

Crunching on.....
