Lots of errors found with memtest86+ any ideas why?

I was rebooting an older machine today because it had been having some issues. I couldn't figure out what was going on with it so I removed different pieces of hardware and tested the components. Turns out the entire issue seems to be with the memory. I have some ocz platinum xtc rev2.0 ram in there now, just 2gbs dual channel and it had over 2.5 million errors before the first test got to the end (at which point it crashed unable to continue to the next test). Any idea what would cause such an issue?
 
Voltage, timings, bad memory, mobo settings. Test one stick at a time. Check mobo settings vs. OCZ's site.

It is impossible for the test to determine what causes the failure to occur.
However, most failures will be due to a problem with memory module. When it is not, the only option is to replace parts until the failure is corrected.

There are some systems that cause Memtest86 to be confused about the size of memory and it will try to test non-existent memory. This will cause a large number of consecutive addresses to be reported as bad and generally there will be many bits in error. If you have a relatively small number of failing addresses and only one or two bits in error you can be certain that the errors are valid.</a>"

Your problem may not be memory alone.
If you're OCing, drop back to default and retest

Also disable Legacy USB (DOS) support in BIOS. You don't state your configuration but there were some issues with Memtest 86+ and USB Legacy BIOS support on Intel chipsets a year or so ago.
 
The motherboard I am using is an asus m2n-sli deluxe, amd 3800+ is the chip, and I have an evga 7900 gto video card. I haven't changed anything about the machine recently. I do have a usb keyboard plugged in but there have been no issues with it at this point.
 
The issue was not with USB devices, it was with DOS based memory diagnostic utilities when USB Legacy Support was enabled in BIOS. The result being spurious errors reported by the memory test.
