Beep code 4-2-3-3 when ATI HD5770 inserted into Supermicro C2SBX board
Currently running a Supermicro C2SBX with fanless Gigabyte ATI HD4850 inserted. It's been running fine for two years. Dual monitors.
I recently replaced my old CRT monitor with a new LCD monitor, so now I have two 24" Eizo monitors (each running at 1920x1200). Unfortunately, the HD4850 only has one DVI connector so I've been running the new second LCD in analog mode using the VGA cable. It still looks beautiful at 1920x1200 but I'd really like to run it digitally, meaning I need a second DVI connector.
So I purchased a Sapphire Vapor-X ATI HD5770 card, which has two DVI connectors. Seemed just about perfect, even though I was really wanting another fanless card. But this Vapor-X card has very positive reviews for silence.
Anyway, I cannot boot the machine with the HD5770 inserted into the same PCIe x16 slot that the HD4850 currently lives in. No other changes in the machine were made, so it's exactly the same except for the swapped video cards. With the HD5770 inserted there is no video output from either DVI connector, and instead the Supermicro C2SBX Phoenix BIOS (v2.0) beeps 4-2-3-3.
Beep code 4-2-3-3 means "extended block move", which suggest a problem with video memory (i.e. mapping it, conflict with onboard graphics, etc.) although none of the possible causes mentioned by other users with similar problems on the Internet seem relevant to my situation.
Furthermore, trying out the HD5770 in my second machine (which has an ASUS P5Q3 motherboard in it) sees it work perfectly! So the new video card is not defective, and in fact does work perfectly in that other ASUS P5Q3 motherboard. Obviously there is some issue with the Supermicro C2SBX board... although both boards support PCIe 2.0 which is what this HD5770 video card uses (I believe).
It's not a power issue I don't think, as the C2SBX machine has a 600W PSU, whereas the P5Q3 machine has a 500W PSU. Yes, there are additional drives and cards in the C2SBX machine but honestly I don't think this is power related. It's most likely some other BIOS incompatibility between the C2SBX and HD5770 that just is not a problem when using the HD4850.
Anybody have any thoughts or suggestions? Any BIOS engineer experts out there who have experience with 4-2-3-3 (extended block move) in Phoenix BIOS?
This is already the second HD5770 I've tried, since I RMA'd the first one believing it to be defective. However since this second card works perfectly in the P5Q3 I'm certain this card is not defective.
