Memory problem


Feb 24, 2013
Hi everyone,

To get straight to the point, today i installed IDIF57J5 D312GB 1600-999 Vengeance in my pc. Now the problem started when Windows and my BIOS didnt show the 12GB that i installed. Instead it told me it was 8GB. So i figured it was 2 things:

1. One of the memory components was broke or
2. One of the memory slots broke.

Well after switching every memory i figured none of them were broke and they were all fine. And at a first glance it started to look like the memory slot was broken. But there was something odd about it, Because once i only put a memory in that slot (so only 4gb) he started up, but no screen .. no bios or anything. Just a black screen. So i figured that i might just had to update my bios to solve it. But nope nothing changed.

And now the funny part, I installed Hwinfo64 and it actually showed me he found 12GB. So what the is the issue here? Windows 7 ultimate and bios found 8GB yet HWinfo finds 12GB ?

My hardware

Intel Core i7 920 Boxed
Asus P6T
EVGA GeForce GTX 560 Ti Superclocked x2
Samsung Spinpoint F1 DT HD322HJ, 320GB x2
Antec Nine Hundred Two
Scythe Mugen 3 PC Games Hardware Edition
Corsair Vengeance CMZ12GX3M3A1600C9
Cooler Master Silent Pro M1000

Can anybody help ? :)
