Eyefinity on PCI x 16 v1?

[jrich523]

I have an Asus Crosshair (the original) which has a V1 PCIx x16 slot. im going to assume this wont cut it, but i figured i'd ask.. dont really want to have to get a whole new system if i dont have to.
also i dont expect anything nuts.. just ok FPS and ok res... enough so that it works and doesnt flicker..
i will be using 3x 24s

Thanks

Pretty sure that's what my DFI board has, and it runs Eyefintiy on a 5870 without a problem.

I recall reading up on the PCI-e 16x versions many moons ago. Back then, it made an insignificant difference. By now I'm guessing that the card will still work, but we'd both benefit from moving to 2.0.

..i'm kinda kicking myself for being too cheap to move up to a i7 system instead of buying this one last CPU for my current mobo.

Anyone want to buy a barely used LG775 Q9550?

There was a roundup I read a while ago sorry couldnt find it but the difference between PCIe 2.0 8x and 16x was only a couple of percent even on the 5870.

So you will be fine with that motherboard for a while then you can upgrade to PCIe 3.0 in the future :D

Actually I found it so ignore my waffling and check the roundup :lol:

thanks for the response guys, i think i try my luck and just buy the card... if i have to get new hardware, ohh well..

sideeffect, thanks for the link, but that only takes about scaling the X value, not the version of pcix. i have an x16, its just that its version 1, not 2 or 2.1

hopefully it will be ok..

PCIe x16 v1.x has the same speed as PCIe x8 v2.x. They are exactly the same bandwidth of 4 GB/s So you can make direct comparisons.
