(Message 36601) Posted 17 Feb 2010 by Jeremy Post: I finally got the HD4850 and was able to install it. Windows 7 recognized it and installed the drivers but BOINC won't recognize it. Windows 7 is still reporting 3GB of total system memory. I'm going to follow David's advice and get the stuff needed to make a dummy plug so I can get it and the GTX260 to crunch together. I went ahead and took the GTX260 out until I get the dummy plug and am now running the HD4850 solo. So far it's roughly crunching MW three times faster than the GTX260! I am, however, noticing a significant graphical lag now. Vincent i have several dvi connectors if you'd like me to send you one...

(Message 36595) Posted 16 Feb 2010 by Jeremy Post: I have a GTX260 that I run wih twin 5970's in Xfire mode so it is possible. I also have a 4770 that I run with twin 5970's in xfire mode, so that is possible as well. You will need a separate dummy plug or monitor ( I use the spare VGA cable) for the second monitor. And also extend the desktop across both screens in Windows. I have had this config working in both Vista and 7, so you can do it. Getting the right cal driver can be a bit tricky though. 9.12 Hotfix seems stable for me. Thanks for the info.

(Message 36573) Posted 16 Feb 2010 by Jeremy Post: Jeremy, I'm actually trying this with a GTX 260 and a HD4850. The HD4850 should be arriving tomorrow so I'll let you know how it goes. From what I've read both Windows XP and 7 support running two different video card drivers. Vista on the otherhand can only run one video card driver at a time. Does your system correctly show all the ram? I'm running Win 7 x86 but I can get a copy of Windows 7 Pro 64-bit for only 80 bucks. Vincent I upgraded to windows 7 x64 today. 32 bit systems only allow for 4gb of memory(total). Graphics cards are included in that allotment. With a gtx 260, 4gb of ram and a 4770 on its way, I'll be around 5.5 gigs. Please do come back with some news... I'm not expecting my 4770 in until the end of the week so any experiences shared are welcome. I'd like to get as much info out there as possible for others as, through my own research, there isn't much out there regarding the subject and what can be found is dubious in nature.

(Message 36510) Posted 13 Feb 2010 by Jeremy Post: I see that another user has claimed to have gotten such a setup to work but there's no nvidia GPU listed as in use under his account. Running windows 7 x86 I'm assuming I'd need to upgrade to x64 for BOINC to take advantage of all of that memory(I already have over 4gb system memory between gtx 260 and ram)...? What little I've read on the matter says that this is not possible on Vista. Anyone know if the same's true for 7?
