Normally I'm pretty good at sorting out my computers, but this one has me very puzzled.
I got myself a Asus RadeonHD 5750 card, and tried putting it in my main games PC to replace an 8800GT - and it didn't work. The machine didn't even beep at me, just started flashing the HD light. (It does produce a beep pattern if I give it no graphics at all.) It hasn't got far enough for driver conflicts to be a possibility.
Now, I know the 5750 isn't much faster than an 8800GT in most of the benchmarks, but I think it'll be worthwhile for some specific things that I run. I can use the 8800GT elsewhere.
The bizarre thing is that we have an AMD CPU, an ATI Xpress 3200 chipset, a m/board made by Asus, a card made by Asus, and a GPU made by ATI/AMD/whatever - and they refuse to work together. The PSU works (I measured it, including the PCIe dongle), and the power consumption of the 5750 should be *less* than the 8800GT anyway.
I put the 5750 in a different machine - with a slightly older m/board with an AMD CPU, an ATI Xpress 200 chipset, a m/board made by Asus, and a smaller PSU (which I had to use the PCIe power adapter with, since it didn't have it's own). It works. But that machine runs Linux, which isn't what I got the card for.
A much smaller RadeonHD 4350 - not from Asus this time - works in the same slot on the Windows machine, and there are no driver conflicts. This is the card I got for the Linux machine I used for testing.
There is a second PCIe slot, but none of the three cards will fit in it, because there's a capacitor in precisely the wrong place on the m/board, which hits the DVI socket on each card and prevents them from seating. I think I have only one card that will fit in the second slot, an "old" X1950 Pro which I already know doesn't have the performance I'm looking for.
I already took one of the 5750s back to the shop, because I couldn't believe that this kind of conflict - between components made and assembled by the same companies - existed in this century. I dug deeper when the replacement acted precisely the same way.
What I might have to do is leave the 5750 in the older m/board, and change the CPUs and HDs over so that it runs Windows while the newer board runs Linux. This would have *some* advantages, mostly since the newer board is also in a huge case which I could use to make a fileserver, but I'd prefer to have the choice.
Any ideas from the peanut gallery?
