I have assembled a new computer with these components:
Motherboard: GA-890GPA-UD3H Rev. 2.1
Memory: Corsair Vengeance CMZ8GX3M2A1600C9
CPU: AMD 1090T
Graphics controller: motherboard's internal only
BIOS version: FF
I did not try to overclock, and the memory has alway been set at 1333 MHz.
The problem is that sometimes it stops recognizing one of the memory modules. This has happened both in Linux and Windows. I Don't know how to reproduce the problem using these operating systems; it *seems* to be random (but I suspect it isn't). The only way I believe it can be reproduced is with Memtest86+; as soon as it starts, it recognizes only one module, and from then on, both with Linux and Windows I have only half the installed memory. I did not try enough times to be sure that Memtest86+ is a way to reproduce the problem.
The way I have found to get both modules working again is:
Swithch off the computer.
Take away one module.
Start the computer with the remaining module: It does nothing but long beeps.
Switch off the computer.
Move the module to another slot.
Start the computer: if it doesn't start and beeps, move it again to another slot till the computer works.
Once the computer works with one module, switch off the computer and add the second memory module.
If the computer works with both modules, switch it off an put both modules in the right way to get double channel.
Once, only once, the problem solved doing nothing but leaving the computer switched off overnight.
Well, where do you think it is the problem? it sounds like a fault in the mother board; do you agree? or maybe the RAM? maybe the CPU? Have you ever heard about this?
Just in case it were relevant, I was never able to see the AMD 1090T turbocore feature working, although it is enabled in the BIOS. I was about to start a new thread with this topic, but I mention it here just in case it were a clue for something.

Memtest modules ......one at a time in slot one for your board type.......10 passes each.......report back with result.

Thanks a lot for your answer, Aussie Allan. This time I was not able to start the computer with one of the modules, regardless of what slot I moved it to. I is clear that that module is defective. I'm afraid I damaged it when I removed its heatsink. I needed to do so, because the CPU cooler did not allow me to put it on slots one or two.
Once again, thanks a lot.

If you need anymore help and or advice.....just ask..........at some point, sometimes we need to remove heat-sinks off memory......when there warm (hair dryer) the covers will come off a little easier without doing damage but extreme care and patience is key......don't feel too bad, done it myself

The problem being that you really should RMA the complete set of modules as they come as a matched set.

True! but it comes down to ethics when we damage bits our selves ....... can we expect to RMA when it's self inflicted, having a conscience can be a bitch........but I sleep better at nights ;)

Try sleeping tablets Allan they work a treat! ;)

What! and take away the kids supply!

Thanks to all for your answers. I agree with Aussie Allan; it would not be ethic to RMA the modules.

Fair enough, I had heard there was someone else around that was honest! Trouble is apart from us there are very few. ;) In that case you will need to replace the entire kit. You might be able to use the good modules in a system somewhere or sell them on Ebay.
