GX620 mini tower adding memory
I have a Dell Optiplex GX620 Mini Tower with Windows XP Pro Pkg 3 Dual Core 3Gb using (2) 512MB-1rx8-pc2-4200u-444-12 Dimms. I am trying to ADD (2) 1GB 1rx8- pc2 5300u-555-13-zz Dimms. On booting BIOS loads, I can go into setup and see all four Dimms. The 1GB's in slots 1 and 2 and the 512mb in 3 and 4. After escaping setup Windows starts to load, I get the black Windows page with the Windows logo and the name Windows XP with the bar underneath scrolling back and forth for about 15 seconds. (I assuming Windows is trying to load) Then the screen goes to a solid blue page with text only saying:
***Hardware Malfunction
Call your Hardware vendor for support
NMI: Parity check/memory parity error
*** the system has halted***
The only way out is to unplug the power and pull the 1gb 's out.
Before going any futher I will say that last week before Crucial, I had bought a set of Centon except they were 6400's 1Gb's. I had the exact same problem. I thought their 6400's were not compatable with my motherboard. So I returned them to the store, due to the fact they were very slow to respond online to my problem.
Here's what I tried with Centons and now the Crucials:
I removed the 512MB's and just tried the 1GB's in slots 1 and 2 and I see them in setup under memory. Same problem I had with Centon. Here's what's strange, I can put one 1GB in slot one and the computer will boot and load all the way. I can do this with either 1Gb dimms and I did that with the Centons.
Are the 5300's not compatable with the Motherboard as well as the 6400's that I tried of Centons?
Anyone ever have this problem? I do not believe there is a DIMM's problem as being defective now, just not compatable or my motherboard is messed up or maybe BIOS? My BIOS is A11
I have seated and reseated the dimm's:emotion-8:
The slots seem good because I can put the 512mb's in 1 and 2 or 3 and 4. As stated above I can see the memory in setup in all slots.
**** I also posted this at Crucial's site forum
Any help or suggestions appreciated
HELP
thanks

Thanks Bev,
I do have a post in their (Crucial) forum and just waiting on their response also. I do not believe it's their DIMMs that is the problem though. I tried Centons (6400's) as well with the exact same problem :( I also have a set of DIMM's I am waiting to get to me from Dell (6400's also that Dell said would work, we'll see). I chatted with Dell support today, he said he had not seen this problem before, and that it may be the motherboard. I just recently bought this machine from Dell Auction. The manufacture waranty is out but Dell Auction has a 90 or so warranty, so I just left them an email . What's strange is that 512MB 4200's will work in slots 1 & 2 or 3 & 4. The 1gb's 6400 nor 5300 will work in pairs at all on this machine in any slot, but a single 1gb dimm will. :(
reboot

Just in case anyone is interested, I believe I have this resolved. Here is a brief mesage I sent elsewhere of solution. It's been a couple of days now and a few reboot at that loading and restoring some files and folder from a backup (which is another problem i'm having now and will present in aonther post):
