Hi Lsdmeasap, I would greatly need your help. Just bought my new PC and found out that it's not stable when running DDR2 2GB dual channel. The symptom is my PC will freeze/hang anytime. I've tried with games like CoD:WaW, NFS:Undercover; it'll sure hard freeze when in-game in few minutes.
Solutions tried:
- update the BIOS to F9a
- tweak DRAM voltage[1.9V], MCH core[1.2-1.3V] (even more unstable, system rebooting)
- sometimes freeze in BIOS when running dual channel
- all hardware settings reset to defaults (doesn't resolve)
- install different OS (Vista x86 & x64) (not the root cause)
- run memtest (sometimes freeze also)
- remain only 2GB DDR2 in a slot (works fine in windows, but still freeze in game)
My PC specs:
Intel Core 2 Duo E8400 3.0GHz/1333/6MB
GA-EP43-DS3L
Kingston DDR2-800 2GB (valueRAM) (2GBx2)
Gigabyte ATI Radeon HD8450
Silverstone PSU 500W
Seagate SATA 500GB
Vista Ultimate x86 & x64 (tried both OS with the same problem)

Questions:
- should I flash the BIOS back to F8 at the moment?
- will the coming full version of BIOS fix this issue? when will it be available?
- anything else can be done if your recommended settings still doesn't solve the freeze problem?
