1  Other / CPU/GPU Bitcoin mining hardware / Desktop Display stuck at 640x480 with hd5870 on: July 29, 2011, 03:09:43 AM
I'm running an HD5870 headless and when I connect via VNC the resolution is at  640x480.  That's the only resolution that I can get. It worked fine with my hd5830 in there so it has something to do with the new card. I have it located in a place where there's not really room for a monitor, so I'd like to figure out how to get this to work without having to plug in a monitor.  I had Catalyst 11.6 installed and applied the 11.6b beta patch that supposed to allow multiple monitors to work without dummy plugs (waiting on some extenders from cablesaurus so I can run the 5870 and 5830 on the same mobo).

Anyway, any suggestions or ideas would be greatly appreciated!
2  Bitcoin / Mining / Mineral oil cooling on: June 07, 2011, 01:54:59 PM
 I live in the South and have my 'beater' pc in the garage, where it runs too hot to mine right now, so I'm hoping this will be able to keep it cool. I'm surprised that no one has mentioned mineral oil cooling on here - or at least not that I have found.  I've always been fascinated by the idea, but haven't ever tried it out.  I can use my beater PC with an old nvidia 8600gt. I figure if it doesn't work, then I'm not out much Smiley

Here are some examples:

http://www.instructables.com/id/Mineral-Oil-Submerged-PC/

The crowd around here seems really experienced and I'd like your thoughts. 
I think the pro's would be:
1. relatively cheap for a cooling system (compared to water cooling)
2. quiet, like really quiet
3. less power used on cooling the system (like the mining rig pics with multiple fans pointing at each gpu)
4. fun weekend project Smiley

Con's:
1. run the risk of frying your board
2. ?

Personally, I'm thinking of going all out ghetto - using one of those plastic pans/buckets that you get from the hospital, and then hooking up an old transmission radiator and a fish pump to move the oil.  I'm hoping that the movement of the oil will be enough to keep the heat going to the surface where it will mostly dissipate and then the radiator will get the rest.  I hope to get away without even fan cooling the radiator! 

If it's still too hot, I guess I could drop the whole thing in the refrigerator Smiley

Anyway thoughts, suggestions, referrals to the insane asylum?
