A few months ago, one stick of RAM stopped being read - On startup, I got the "amount of system memory has changed" message. It has happened about five or so times since then, and each time I was able to get it to read again by removing the RAM and reseating it (most times, though, it takes multiple tries). I tried switching the sticks a few times to find that it still worked or didn't work about the same. It's never both though - only one that doesn't read. I think that it's a faulty slot, but I'm not sure.

Can anyone recommend any troubleshooting tips, short of switching out the entire motherboard? I really don't think that's much of an option for me. Thanks in advance.

PS - If any other system info needs to be posted, just ask.

It sounds like your ram could be failing. Try running memTest86 and see if you get any errors. If possible run the memtest while all of the ram is recognized.

It's possible that your motherboard slots are bad, but usually if the ram can register at all then this isn't the problem.

The simplest thing you could do is replace the ram... DDR2 ram is ridiculously cheap.

Not from my standpoint. 4GB of DDR2 is the same price of 8GB DDR3.

1 gig stick of DDR2 667 ram on newegg for $12.
2 gig stick (same type) $20

Yea, it's a generic brand, and it doesn't have a heatsink on it or anything, but he could replace all his ram for $40 + shipping.


Not really sure where you're shopping, but 4 gig stick of DDR3 1600 $24

Unless you are buying the highest priced name brand fastest ram on the market then it's not that expensive.

8GB of DDR3 is ~$40

What you said, $40+ shipping

More for your money.

I'd really get one with heat spreader. You ever feel how hot your RAM gets when in use?

I absolutely have heat spreaders on mine, but I have DDR3 1600 which run very hot. (I used to think they were overrated, but then I burned my fingers after switching some ram out)

It's odd that DDR3 would be cheaper, but for Jack Nitro I assume it's not an option unless he also replaces his motherboard.

That cheaper bit was to your reply of "DDR2 ram is ridiculously cheap". It was not against the OP.
