Memory diagnostics

Question

I have recently acquired a s/h XPS L502x(Core I7). I have increased the memory to 8Gb(2x4Gb) and although I haven't had any crashes or BSOD's (yet) there may be a problem: Running the Dell extended diagnostics returns error code 2000-0123 for several tests, starting with MATS Running the Windows extended diagnostics it hangs at 21% Running Memtest86 returns no errors after 1 pass. Crucial tell me that there is probably nothing wrong, but when out of three tests one reports that there is and another fails I am not so sure. Does anyone have any ideas? (I'm running W7 Home Premium) Thanks PS I have tried each module by itself in each slot with the Dell diagnostics, and only one of them returns errors.

HI DAVIDTRICKETT, Is your memtest 32bit [(Memtest86)], and is W7 Home Premium 32bit or 64bit?

What happens when you run the test on a single stick of 8GB and alternate RAM slots? See if one of your slots is bad, giving the error code for ram failure stated above.

Sorry - didn't see that both responses were from you! Sadly I don't run to an 8Gb stick, but I have tried each 4 Gb stick by itself in each slot, and consistently one gives no errors & the other one gives a fair few. The sticks are, incidentally, new from Crucial and are supposedly a matched pair.

Hi Thanks for your response. Sorry - I should have mentioned that I am using W7 64 bit. And I'm well aware of the memory limitations in the 32 bit version. As far as I can see there is not a seperate 64 bit version of Memtest86, but the version I am using - 4.4 something - shows that it is using 64 bit addressing.
