Problem of memory with Windows 7 64-bit

[Badrunath]

I am having Windows 7 64-bit Ultimate. My config:

- Intel I7 920 processor
- GS Gainward 4870X2
- Asus Rampage II gene
- G-Skill DDR3 perfect storm 6GB 2000MHz
- Crucial M225 - SSD 64GB 64MB 2.5" Serial ATA II
- Samsung SpinPoint F1 - 1 TB 7200 RPM 32 MB Serial ATA II
- Corsair HX750W - Power Modular
- DVD burner Serial ATA II

The problem is that Windows only sees "2GB". I have used CPU-Z and it recognizes the 6 GB. How to solve this problem?

Which version of Windows 7? RTM? RC? However this looks more like a hardware problem that has a bug in Windows 7! Bios update? The strips are clipped? Is it compatibility with your motherboard, as it seems due to the P55!

My version is the final. Bios update and re-checked. The strips are clipped well since we can clearly see the 6 GB. They have existed since the arrival of the P55. But it's strange they are in single channel.

Yes but the HIC is that you are in X58 and not P55! So F3-16000CL9T-3GBDI-B (XMP) see here http://www.gskill.com/products.php?index=184 the memory seems to be compatible with Gskill. See the list of compatible strips http://dlsvr04.asus.com/pub/ASUS/mb/...I_GENE_QVL.zip
