I have a custom computer (local shop) it usues an MSI 6547 V2 motherboard and an AMI BIOS version 07.00T. The motherboard ID is 620113-009999-00101111-040201-Sis645-1AAWV001. I have 3 512MB memory boards installed. All three were purchased with reference to the motherboard manual (DDR2700) What might I do to get the computer to recognize all of the installed memory? PCWizard 2007 version 1.73 reports ROW-0 (RAS6, RAS-11) 512 (Double Bank) Row-1 and Row-2 are shown as empty. Next it reports that ROW-0 is populated with Infineon PC2700 memory 512MB. Then it goes on to state that I have a Kingston PC-2700 512MB card in ROW-1 and a PNY Electronics PC3200 512MB compatible with PC2700 in ROW-2. Any one of the 3 512MB boards will workas an individual but no 2 of them (or 3) will have the full memory recognized. I ran this computer on WIN98SE before switching to WINXP Home and had the same problem with both OSs so I don't think it is an OS problem. Any ideas on what I might try next? BTW, PC Wizard 2007 reports physical memory of 1536MB DDR-SDRAM. As was said in the "King and I" movie, "Tis a puzzlement".

How much memory does windows recognize?

the easiest way to find out is click start, r click my computer, click properties, and see what the general tab says that you have.

I have had issues in Dell and HP laptops when combining PNY and Infineon memory modules (added the PNY) - switching to Kingston fixed the issues.

John,
Speaking of Dell laptops, I have found that after servicing a Dell, that if the memory modules are put back into different slots, the computer will not boot. Just switch the mem sticks and it boots. Weird.

Thanks for the replies.

Checked My Computer properties - WinXP says 512MB.

Will try pulling the PNY module and swapping the modules around and report back.

Way, way off-topic - but I've actually had a Dell in the shop (for memory) that used ECC RAM. Dell must've got a deal on it - but we couldn't upgrade it because of that!

Two things: can you give us the actual model/part number of each memory board.

and try with the kingston in slot 0, and the infineon in slot 1, leaving the pny out.

let us know, please.

Will do. We have guests at the moment. I won't be able to get to this until Monday. My plan was to try all possible combinations of one to and 3 memory boards. I also will try only one board in slot 1 and then only one in slot 2. I had tried each memory board by itself before but only in slot 0. The manual does not require that slot 0 be filled when inserting memory.

If you get a stick that passes the Memory Test, it's fairly easy to rotate it between slots - testing each slot.
If you don't have one that passes, then you'll have to try all the combinations in all the slots (a daunting task)

Also, you may be able to test the sticks in another system (to see if the sticks test good) - then you'll cut down your testing requirements on the PC with the issues. With a known good stick failing on any of the slots - that's a mobo issue and I'd suggest a new/RMA mobo for that.

Did some more testing

None of the combinations tested showed more than 512MB installed per control panel -system. All configurations showed the correct installed memory using PC Wizard 2007 and CPU-z.

Row-0 Row-1 Row-2 Total Memory

I K P 512
I K _ 512
I _ K No boot
_ _ I No boot
_ I _ No boot
K I _ No boot
I _ _ 512
P _ _ 512
P I _ 512
P _ I 512

P = PNY 512 module; K = Kingston module; I = Infineon module

From the above it would appear that Row- and Row-2 (slots 2 & 3 are bad. However, if the slots are bad, how can
PC Wizard 2007 and CPU-Z determine what modules are in them and come up with the correct installed memory count?

Sorry but the forum board did not transfer my formatting very well.

What is the bios count for ram? Also, are the dimms single or double sided?

Just did a search on your model, for a possible bios update, MSI's web site says model doesnot exist.

Looks like something is FUBAR'd there - just to be thorough, I'd test the PNY and the Kingston sticks separately in each slot (to verify that it's the slot and not an incompatibility with the Infineon memory).

The detection programs only identify if stuff is in the slot (lot's less channels than the RAM actually uses) - so it's possible that they can identify the RAM even though it doesn't work.
