Should I be worried? (memory related)

[Kwyx]

So this afternoon while playing a game my computer froze up. When I rebooted it just kept getting stuck on the bios splash screen, I couldn't even enter the bios setup. After removing everything else I got to the memory, (4 x 1GB sticks). I removed the 2nd pair first, and that did nothing. Then I removed the 1st pair and put the 2nd pair in their place. Everything started working, I was able to plug back in all my drives and peripherals and boot up windows with no problems. Just for grins I put the 1st pair of memory sticks back in and tried again. Now it boots up fine with everything.

Basically, all I ended up doing was swap the 1st and 2nd pair of memory sticks into each others slots and all seems groovy now. Should I be worried that I have bad memory? I ran the windows memory diagnostic tool and found no errors. My main concern is that I've only got about a month left on the 90 return for replacement through newegg.

Use the BIOS and enable the full boot up memory tests. You could have intermittent bad memory and moved it to the top of the memory space where it's not being used. Depending on how much memory your MB allows (like 3.5GB max?) you may be ok if the bad spot just moved to the unused high end.

Increase the DDR2 RAM voltage by about +.2v since you are running 4*1GB.

for more information on BIOS settings. After the voltage increase run Memtest86+ through UBCD for about 5hrs and check for errors.

I'll give that a try, downloading ubcd now.

Thanks.
