memory errors

[soccermaniac88]

I am running windows 7 64 bit and recently I have been experiencing some unexpected shut downs. I decided to run memtest86+ and received over 250 errors for test #8 (Modulo 20, Random Pattern). I am pretty inexperienced with this sort of thing and I was wondering if anyone could help me figure out what these results mean. I am currently using 4 x 2gb A-Data DDR3 RAM. Any help would be greatly appreciated!

Have you read any of the tech support information about troubleshooting errors at the memtest86+ site?

Sounds like either bad RAM, bad PSU, or wrong timings/voltage info in BIOS.

How could I test if its the BIOS?

 

[VirtualLarry]

Easy, go into your BIOS, and adjust the timings and voltage to that specified by the mfg.
If you still have problems, something could be defective.

A-Data is not first rate memory. Try removing 2 modules, from the same bank (identically colored DIMM sockets), and test again. If the remaining modules pass, substitute them with the previously removed ones, and test a third time.

Try the other Memtest, Memtest86 v. 3.5a, especially test 5, which tends to fail the memory more often than all the other tests.

The non-plus version of Memtest is very broken indeed. I would not recommend using it.

(The last system I tried it on, it would just reboot after loading, repeatedly.)

I have to admit not being familiar with Memtest86 3.5A on newer hardware, but it did manage to work with 8MB of DDR3, while 3.5 failed on everything I tried, including a computer using just a single 2GB DIMM. I haven't had such a disaster with MemTest+ 2.11, but like many other memory diagnostic I've tried, including Memtest86 3.x, it did occasionally reboot just after loading, I believe always due to memory that was eventually proved defective.
