I got this fault, It looks a bit obvious it's a memory fault, but I want to know if anyone has ever had this fault and what causes this fault and would replacing the memory fix the problem??

Cheers

Short summary and next steps based on the thread: the machine stops early in POST with the message "SDRam at DIMM # : 1,2". reports he can enter the BIOS but a floppy or normal boot does not proceed, and a memory swap did not cure it. and covered the basic checks; suggested an add‑in card might be involved. Because simple RAM replacement didn’t help, the fault is most likely in the board’s memory subsystem (slot/traces/chipset), power delivery, or an interacting component — but you can confirm that with a few targeted tests.

Stepwise isolation (do these in order, powering off and unplugging before touching the board):

  1. Test one DIMM at a time in the primary slot, then move that same single module through every slot and repeat with any other known‑good module. Note which stick+slot combinations allow POST (if any). That pattern tells you whether a particular slot or the chipset is failing.

  2. Run a bare‑bones POST: leave only CPU, PSU, one DIMM, and video (or onboard video), remove all other cards/drives, and listen for beep codes or use a POST card. If the board POSTS with fewer components, add items back one at a time to find the culprit. This will also reveal whether a faulty add‑in (GPU, controller) is stalling initialization.

  3. Visual and power inspection: look for bulging/leaking capacitors and burnt traces near the DIMM area or VRMs; check DIMM socket pins and the socket for contamination; verify main power rails to the board with a meter (consult the manual for expected voltages). Clear the CMOS to reset timings/voltages to defaults and only consider a BIOS update if you can do it safely and the changelog mentions memory fixes.

If a known‑good module never POSTs in any slot and the board still halts with minimal hardware, the motherboard (chipset/slot area) is the most likely failed component and replacing the board is reasonable. Record each test and its result so any replacement or repair is focused and you don’t repeat steps already tried.

Fault is that like and error,when and where do you get this message !

This error comes up when booting. the message 'SDRam at DIMM # : 1,2' comes up, i cannot restart using ctrl alt del and cannot bye pass this.

I can get into the bias and thats about it. Any ideas??

I can't boot off a floppy to get into dos or anything

Go into the BIOS and turn off Quick Boot. Perhaps the more verbose mode will give you more information. Try a MemTest86 floppy from http://MemTest86.com

It could also be something as simple as a DIMM being loose in its socket. Gently try to rock the sticks side-to-side in their sockets. If they wiggle at all, unlatch the loose one and try to reinsert it into its socket more securely. This is a not-uncommon problem.

Ive replaced memory and still the same fault. I think the motherboard is stuffed, getting a new one

its ur graphix card just had the same problem during a uni project where we had to build a computer and locate faults must admit it took our lecturer about 30 mins with us to figure it out but yea turnd out to be a faulty graphix card
