Hi,
Here is my platform:
Asus P5Q-E
E8400
GSkill C4 2x2Go DDR2 PC6400 (800 Mhz) F2-6400CL4D-4GBPK
HD4870, Catalyst 8.8 and 8.7
Vista Ultimate x64 SP1
BIOS is latest version found at ASUS site (flashed two weeks ago)
Here is my "problem":
I bought this (very good looking) CL4 RAM as I expected it to have better latency.
After installation I set it in BIOS to 4-4-4-12 as specified by G.Skill on the RAM box.
Then Vista started complaining randomly about ATIKMDAG.sys which had failed and needed to be recovered by Vista. Sometimes the PC would simply reboot.
The problems occured while browsing (= little CPU activity).
So I decided to run Memtest.
Memtest-86 would show 4 errors in test 5.
Memtest86+ would report 8 errors in test 7.
Then I reset the latency in BIOS to 5-5-5-15 and ever since all of these problems have disappeared. The system is completely stable (even with Stalker running at maximum settings).
Here are my questions:
1. Why does my system fail when latency is set to CL4 settings (4-4-4-12) as according to G.Skill the CL4 RAM is supposed to support it?
2. Which are the benefits for buying CL4 for this Asus P5Q-E motherboard as it needs to be set to 5-5-5-15?
3. As I intend to add further 4 Go of G.Skill RAM do I need to buy CL4 or will I also get dual-channel capacity if I add CL5 (2x2Go) (BIOS being set to 5-5-5-15)?
Thank you in advance for your assistance which is greatly appreciated.
Best regards
Michael
