Not that I will see any performance boost, or that I would be better off by just buying a higher end card, lets say just for the sake of discussion....If I installed two identical crossfire 'supported' graphics cards on a crossfire enabled motherboard, do I need a connector cable to couple the cards or will the motherboard recognize the setup and couple them for me? If a cable or jumper is needed where might I purchase one? Anyone know? The motherboard in question is an ASUS M2R32-MVP and the cards are ASUS EAH4670/DI/1GD3/A. I guess I just have too much time on my hands and would like to see if I can make it work. Any help again would be greatly appreciated!
A Crossfire bridge is needed for them to work in CF. Like this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16814999002 Usually higher-end cards come with one of these, but 4670 doesn't exactly count as one. If you were to try Crossfire, at least don't get those 1 GB models. 4670 gains minimal to none to negative performance gains from 1 GB of memory.
Thanks for the infomation, I saw that bridge at 'new egg' but wasn't sure if it would work with these cards or if it was even needed. If you don't mind, pardon my stupidity, but why are the 1GB cards productive of none to negative gain and what would you suggest for a crossfire setup? (I have read your posts and understand you are not a fan of crossfire just trying to educate myself here) Thanks for your reply! I currently am using a PNY card with only 512MB of memory I just thought that if I increased the memory X 4 that it would be an improvement. Please explain if you have the time or point me to a site thaqt may help.Thanks again!
Video card memory means next to nothing in performance. Amount, frequency of shader cores, the general architecture of the card means the most. A card around the level of 4870 gains performance, in some/many cases from more memory, under that, 512 MB is enough to max out the potential of the chip.
What is your "PNY card"? Can't say anything about it without the model.
You seem to be a real RAM fan... You got 8 GB of RAM in a WinXP 32-bit system... That means 4.5 GB of RAM doing absolutely nothing... I can see how you'd like your video cards having as much memory as possible...
Also I'd like to ask. Do you even have a Crossfire capable motherboard? What is your power supply? MODEL. Not the wattage.
I will have to pull the old graphic card to see the exact model as I dont remember, thanks though, the modularity of the new PSU is what I was looking for (beside power and 'crossfire' ready as this one is as well.) when I bought this one. As I already have it ( I only have limited time to work on it as my time off from work is quite limited) I guess I will go ahead and keep it. Thanks again so much for your reply and help.
"Crossfire ready" doesn't mean anything if the PSU is low quality and otherwise bad, but I'd think it will suffice somewhat.
No need to pull the card for an exact model number, just post the model (HD2400 Pro, 9600 GT, etc is enough).
The new cards came in today (new egg service is great) so I'll pull the old one soon enough and let you know. thanks again! (and on the 'crossfire ready' issue, I think they pretty much all say that.)
