Is 1 ram error too many?

Tested a new lappy (Lenovo W510) with 6gb of DDR3 ram. At 100% coverage, Memtest for Windows shows me 1 error. I have yet to find which module has the error.

Can my customer use his lappy with such discrepency?

Yes 1 error is too many, I would check the bios settings and then test the sticks individually

Did so. Found 1 stick that would show the error. No settings BIOS-wise can be changed for the ram on this laptop.

Bad stick, replace it. 1 error is too many. Every time your computer accesses the bad register it will hang.

Are you getting the exact same error each time? Usually bad RAM will throw up random errors all over the place.

Also, what version of Memtest are you using? The bootable CD version, or the windows version? If it is the bootable variety, you can stick with test #5 in Memtest as that will almost always throw up errors if there is a problem.

But yes, as others mentioned - even one error is too many.

Random lock-outs from the OS is what happened. Hence why I tested the ram using hcidesign's Memtest for windows.
Stick was removed and the other 2 sticks are fine. What I'm concerned about is that W7 was installed using that stick. I wonder if it corrupted the installation.

Yeah just replace the bad stick. If windows was working originally then it should be fine, otherwise reinstalling is easy

I recall that memtest should have USB legacy support disabled too or it can cause problems. A laptop may not have this option though, and I still think your ram is bad, and like the others said, replace the ram.
