BIOS and OS only recognizes 2 gigs of RAM


Recommended Posts

Like the title says, in my sig rig, both the BIOS and Windows x64 are only recognizing 2 gigs when I place my extra 512's in the yellow slots for a total of 3 gigs at 2t.

Any explanation(s) ?

 

Thanks.

Hello,

 

Not recommended (may not work or be unstable)

1, Mixing memory modules that have different capacities

2, Mixing memory modules that have different chips/IC spec

 

+, Mixing on a Dual channel memory controller = more of a problem.

 

Always try to match the Make/Model/Revision of the memory modules.

Hmm... all of my sticks are OCZ Platinum. 2 are 1 gig sticks in the orange slots, and when I add the other 2 platinums (512's) into the yellow slots, the machine runs fine, but it doesnt even see the extra memory. The BIOS and the OS report only 2 gigs, when it should be 3.

I could understand the machine locking up or not posting, but why does it not even see them?

Module densities are different. (1GB and 512MB)

Also OCZ may have used different chips on the 512MB modules.

 

Try the 512MB in the orange slots and 1GB's in the yellow slots.

What happens?

 

No post or 1GB goes invisible?

No post that way. :(

 

Well, this is somewhat disappointing; I was hoping to benefit from some extra memory for Adobe Premiere Pro.

Do you think if I get 4 identical modules (2 more 1gig platinums) it would work?
