Sorry guys, I should have added more information. I do 90% video editing and photos, very little gaming and it's FSX. I purchased the 4GB (2x2) Kingston HyperX DDR2-1066 on sale for $61.99, thinking I could run it with two sticks (2x1) of my Crucial Ballistix Tracer DDR2-1066 giving me a total of 6GB of Ram. Both brands are listed at DDR2-1066 5-5-5-15 2.2v. My 4GB (4x1) Tracers will run at 1066 2.2v 5-5-5-15. I can not get the Kingston to run at 1066. I even tried it by itself setting timings, voltage, and speed manually and it would not boot past the ASUS splash screen. I raised the NB voltage to 1.51v and still no post. The Kingston 1066 will post if bios is set to auto, but at 800MHz. The best I have been able to do is the following
Dimms A1-1GB, A2-2GB, B1-1GB, B2-2GB @ 800MHz 4-4-4-12 and 2.2v
I hate to take the memory back because it is not on my MB's QVL so I kinda bought it just hoping I could get it to run together.
Any suggestions, and be kind!!
