Memory Installation problems

Hi, I have installed this motherboard and am having issues with the memory.
Here is the memory that I have:
I inserted one stick in Channel A(0) and the other in Channel B(0) and when I booted, got the 3 beep code which I found out was a memory code.
I then took out the one in Channel B(0) and tried to boot with just the one stick in Channel A, got the beep codes. I then took the one out of Channel A and put a stick in Channel B(0) and it booted with no error codes, just rec'd a message that in order to optimize the dual channel memory that Channel A and B need to have the same size ram.....

So I proceeded in singular channel with the one stick and loaded the OS. I then loaded the drivers for the mobo. I was able to restart 2x with no issues.

Out of curiosity, I then added the other stick into Channel A and it booted all the way through to the OS with no issues, no beeps, but when i tried to restart the system, I got the beep codes. I tried this 2 more times with no luck.
I have tried installing the ram in differnt slots as singuler channel and it was no go, the only slot that is fine is Channel B(0).

I did remove the cmos battery and replaced it with a new on, did not make any difference.
Do you think the mobo is bad? Is there something that I am missing? Any other ideas to try?

    Yes I tried both cards in Channel B and no issues. I even tried installing known working cards from another similiar system and same results. I was thinking of trying a different PSU but didn't know if that would cause such problems but I suspected a bad mobo, Thank you for affirming what I thought was the problem.

Intermittent problems just about always indicate a hardware problem. Assuming that you've put both memory cards in channel B and they worked fine, I would think the memory cards are OK. The only thing left at that point is the motherboard.

I need changes my memory 2 pcs @ 1GB DDR1 PC3200 with 2 pcs @ 2GB DDR2 PC6400 in Asus P5VDC-MX Motherboard. please advice. Thank you

Number of Memory Slots: 2×184pin + 2×240pin
Memory Standard: DDR 400/DDR2 533
Maximum Memory Supported:2GB

PC6400(DDR2 800) is not supported by your motherboard. Also max memory is 2GB. PC4200 is the fastest memory you can install. There might be a BIOS update available from ASUS website to increase the speed but you would have to check the site.

I have a intel 845gvsr board, want to replace a Ram. What type of RAM is suitable for this board?

Your Intel D845GVSR has,

1. Two ram slots.

2.Maximum Amount of ram is 1GB for EACH ram slot.

3.Maximum TOTAL Amount is 2GB, (1GB in each ram slot)

4.Uses DDR Sdram at 400MHz, (PC3200), OR
DDR Sdram at 533MHz, (PC4200)

This is an example of DDR Sdram at 400MHz, (PC3200),|c:1352|&Sort=0&Recs=10

(Not advertising for this website. There are many places to buy ram memory)
512MB + 512MB = 1024MB, or also stated as 1GB
1024MB = 1GB

Pc4200 memory 1 GB doesn't fit dc 7600 sff

Make sure that the memory that you have purchased is DDR2 memory, this type will fit into the slots.
DDR & SDRAM however will not.
Check the memory is the right type, if its not, take it back and swap it for the right type.

Want to install 1024mb memory on dfi cw35 system board. Possible?

Maximum memory for that motherboard is 512MB, sorry. You might get more to run on it, but its very unlikely. I would spend the money you have on a more updated motherboard and cpu.

Acer 3680-2633 won't boot with new ram install

Dont be hasty! First of all, not all ram and motherboard are created alike.
1. go to the specifications of the RAM and find out what voltage its expecting from the motherboard. this may require just looking at your receipt or going the the manufacturers website and looking at the specs or calling them.
2. check your motherboard manual or access it from the manufacturers site and check the highest voltage that it will supply to the RAM.
if the RAM Needs more voltage than your motherboard supplies, it will cause the symptoms your describing. In this case you will need to find some PC4200 ram that runs at your motherboards voltage.
I have ordered many barebone computers that were shipped with upgraded memory that wouldnt work on that system, the sales people are more interested in selling than checking the specs.

Memory Stick Installation

So it seems you got the DDR / DDR2 side of the equation correct, but unknown to most, there is 'low' and 'high' density memory.

The density of memory refers to the number of chips used to make the total amount of memory that your memory stick contains. e.g. High density memory has few, large capacity chips to make up the 1024MB of memory on the stick, whereas low density memory uses many, small capacity chips to make up the same 1024MB total on the stick.

Typically, if it is a low / high density conflict, it is the 'low density' sticks only that will boot.

Me, I purchase Kingston memory when I'm unsure what the motherboard will be, and it has never failed to work.

I fix computers.
