RAM not detected

Hey guys, how are y'all?

I am having a problem with the RAM on my pc. I have 3 x 2GB DDR3 RAM sticks but only 2GB shows up in Windows and BIOS.

Someone here had a similar problem and he was advised to remove his RAM sticks and insert them in again, which worked. I did the same thing and ran the Windows Experience Index and Windows picked up 3 x 2 GB correctly. Everything was fine for half an hour before I received a message saying new hardware has been detected and I was back to 2GB again.

I checked BIOS, and like Windows, it only shows 2 GB.

I ran the inbuilt Windows Memory Test and no problems were detected. I also downloaded and ran Memtest86+ v4.20 for more than 20 hours (51 passes) and nothing showed up there either.

Surprisingly, Memtest86+ picks up all 6GB. This information conflicts with Windows and BIOS and its very confusing!

I then phoned the company where I bought my pc from - I have a custom made gaming rig - and explained the situation to a guy from tech support and he was stumped too.

What befuddles me even more is that I haven't carried out any hardware changes since I bought the pc. Also, because I use this machine mostly for gaming the only software I installed in the past one year are Windows 7 updates.

So I'm all at sea now and would greatly appreciate any feedback on this issue.

I will put up screenshots from various diagnostic tools in the next post.

I apologise for the length of this post but thought I'd give as much info as possible. Thank you.

Clear your CMOS and try installing one module at a time and see if they boot (it should boot IMO). If they boot individually then try updating the BIOS and then install the memory together. Hope that helps.

Thank you, didn't expect a response from GSkill directly :) I'll try boosting the voltage and keep you guys informed. Just for clarification - and please excuse my ignorance - my RAM is not showing up correctly because my PC is overlocked, right?
