Ram problems!!!

post #1 of 13
Thread Starter 
I have 8gb of G.SKILL Ripjaws ram(4x2gb@7-8-7-24 1.65v)and recently only 6gb shows in the bios. I have tried every stick individually and tried all four slots in the motherboard and they all work. I am on win7 64bit and in windows it says I have 8gb(6gb usable). It has never done this before. Any help is appreciated.

Edit: I have also ran memtest 10 passes with no errors and memtest shows 6gb also.

Test each stick of RAM in memtest individually.. One of my 2GB stick failed in the test and I RMA'd it.

I ran memtest on all four sticks individually and they all passed with no errors. So we can rule that out.

Ok, I found the Problem. If i overclock my cpu any at all for some reason only 6gb of my 8gb of ram shows. Could the memory controller on my cpu be going bad?

It could be a motherboard issue - perhaps BIOS issue. Try updating it.

Im running the newest bios for my mb 1.9. I just noticed when I run Prime95 blend, like five minutes in at stock speeds my fourth core always says fatal error, rounded to .5 was suppose to round below .4. And when I overclock It I get the same message the instant I start Prime95.

Raise your CPU-NB and/or RAM voltage a little bit(1-2 notches and test)

I tried that and still fatal error. Im convinced that its either my CPU or my mobo, leaning more towards my CPU. If anyone has anymore suggestions I'm open to try anything. Thank you everyone for all of your help.+rep

Thats a CPU-NB/RAM error, but sometimes may show up due to a low CPU voltage. Try run IBT or LINX (10 times) . If passes the CPU voltage is OK.
