Hey pals, so, the thing is: I have 2 64GB SSD's.
I did Raid 0 w/ them.
Everything went fine.

1 little problem:

I have 1x4GB Corsair Vengeance memory stick (2400mhz)
When the machine was running on IDE mode w/ 2 independent ssd's, I could use the 4GB properly.

Now, w/ the raid 0, I can only reach up to 3,89 GB? WHY DA H3LL?

Pls help, tnks.
