Dual 5870's

[Mike029]

I can't quote where I read it, but I seem to remember someone (one person) mentioning that cross firing them for boinc was not the way to go. I can cross fire them (one is a 2mb, other is a 1mb, if that matters).

For what it's worth/not worth, my mother board is a P5W DH Deluxe.

Personally, I enjoy all the discussion, lots of food for thought. I'm going to the local Radio Shack tomorrow to set up the dummy plug just in case. I've got 235.00 is the two GPU's (one sitting next to me on the desk ) so what is another dollar or so.

Let us know how ya make out Phili. Being from New York, I won't hold it against ya. Giants, Rangers, Islanders, Yankees, etc (forget the other teams) OHHHH!!!!

Off topic but, ya had to go there did ya Eagles suck, Phillies great, Flyers great, Sixers who? Elite Manning (not), Rangers pretty good, Islanders -admit to owning them? Yankees had a good season, disappointing post season like the Phillies. What about the other teams in the State of NY, Buffalo Bills - please, Mets or Mess is more appropriate. Oh, forgot the Knicks and Carmellllllllllllo and Amar'e don't play defense Stoudemire.

Always fun to banter back and forth between the two sports cities - no doubt NY wins hands down on championships.

Ok, back on topic, lol.

I'm going to Radio Shack this morning to get the resistors to make the plug and then reinstall the other 5870.

I read 'somewhere' that it was ok to have the 5870 installed without the power plugs instead of taking it out which confused me. One time (of my many times trying to get the 2 to work) during my install/uninstall of the card I forgot to install the two power connectors and the card made a nasty winnnnning sound.

Also, any other thoughts on the cross firing of them?

You don't have to run them in crossfire for crunching. You get more credits not doing it.

This is sort of on topic. In an attempt to free up a pcie slot for a very slow gt430 I moved a 4850 to my cruncher1 box. It now has a 6950 in the pcie x16 slot and the 4850 is in the pcie x1 slot. These are both crunching mw (sorry, can't go for credits all the time.) What I found interesting is that the wu times are about the same...cool. Anyway, to get them to work I did have to open Catalyst and extend the desktop, but I did not have to use a dummy plug...this is with an XP OS. BTW, I put the gt430 on DiRT cuda for a few more credits...Al

Hey don't worry about it.

As far as the 4850 crunching wu's at the same rate at the 6950, that is a problem. The 6950 should blow the 4850 out of the water.

I also don't think you would get better credits crunching those two cards on Moo than MW. I thought that you needed to use a dummy plug in XP. Good to know you got it working without it. Big thanks for the help on DiRT.
