Hi, I purchased a new computer a couple of months ago here are my specs:
Intel i7 930
Gigabyte X58A-UD3R
12Gb G-Skill DDR3-1600 PC3-12800 (CL9-9-9-24 1.5V)
When I first got the computer assembled, I only had 6Gb of memory and it was very capricious in terms of how much was being recognized and when. It appears that a cold start usually brought about the problem for most people but in my case, sometimes I would get the full 6Gb from a cold start, sometimes I would get 4. After the cold start, if I got 6 and rebooted I might get 6 or I might get 4 and if I got 4 after a cold start I would get 6 once it heated up a bit and then it would swap back to 4 etc etc... you get the picture. This was on the first day of struggling with the computer and I hadn't read that DD3 and X58 proved to be a pain in the backside for a lot of people... anyway...
As I said, temperature didn't appear to play much of a role when it came to how much memory was actually going to recognized. I did all the troubleshooting, I reseated the memory, I swapped the sticks, I tested them one by one, it all seemed fine but as soon as you would plug in the full 6 gigs, it would just die. Basically something was wrong and I went back to the shops to exchange the memory and the PSU (different story... I think it was faulty as now the new one works fine... anyway)... Considering how annoying some retailers are, I knew that I wasn't going to be able to just come in and exchange my 6 gigs for a new set without them taking the whole thing away... without me having to pay money... blah blah... with the result being quite obvious so I decided to take a risk... I purchased a second set of the exact same memory... so I had 1 'faulty' set and another new one. I came home and plugged the new 6 gigs in... everything was running sweetly now. The new memory seemed to be totally stable... after many many reboots... 6 gigs.
I then went back and exchanged the original 6 gigs for a new set, as I finally had proof enough to get an exchange without all the stuffing around, so I ended up with 2 new sets of 6 gigs i.e. 12 gigs. I once again came home and plugged in the additional 6 gigs... much to my dismay... i was once again seeing not all the memory being recognized... I was flipping between 8 gigs or 12. So... I did the whole trouble shooting thing for each set again... I tested just the first set... swapped the sticks... reseated them... etc... nothing... was getting a stable 6 gigs... took that out... put in the second set... nothing... no problems... once again, I was getting 6 gigs stable no matter how many times I reset the computer.
So basically... there appears to be no problem with the individual sets... but as soon as you plug them in together... bam... I get the old problem of only getting 2/3 sticks from each set being recognized in a haphazard fashion. Any ideas guys? I've finally got some time to sort out the issue, hence not trying to sort it out sooner... been using 6 gigs with the other 6 gigs sitting inside my table waiting to be installed and for the whole thing to finally start working hopefully.
I have no idea what the issue might be or how to continue the troubleshooting because as I said, I've tested each set individually and they seem fine by themselves but together its a different story. I started playing around with over clocking the CPU (not too much... I went from 2.8 - 2.93ghz or something... so on the stock fan still) and as soon as I started to play around with over clocking... the memory started acting up again... maybe it's something to do with the ratio or whatever it's called or something of the sort I don't know... when I get my new case and plug in a better cooler hopefully by the end of this week, I'll see whether over clocking ruins the stability of the 6 gigs... but yer... getting really frustrated with all this to be honest... just looking for some tips.
EDIT: I just read that there might be a mismatch between the two sets of memory... why would this be case? Can't imagine the same model memory being any different in different batches?
