Update: I received two more
captain_videoUpdate: I received two more 2x2GB Corsair DIMMs the same as the ones I was trying to use previously. Unfortunately, I ended up with the exact same result as before. The two new DIMMs failed MemTest86 at exactly the same spot as the previous pair. When I tried to install just the 2x2GB DIMMs by themselves, MemTest86 would cause the PC to reboot right after starting the first test.
I checked the Corsair website and they suggested trying to run the DIMMs at a lower speed so I tried it at the 8X multiplier instead of the default 10X setting. No luck at 8X so I then tried 6X. This time I totally lost video and was literally flying blind. After much trial and error I realized I could set the CMOS jumper to the Configuration setting and I finally got video. I reset the memory clock setting to 10X and rebooted. I have since removed the 2x2GB DIMMs and will probably send them back to Newegg.
Newegg had a sale on a pair of 4GB Mushkin DIMMs that appear to be compatible so I ordered a set. I’m hoping this time I’ll get things working as they should. If not, I may have to consider replacing the motherboard. One other option is to reinstall the original MSI K9A2 Platinum motherboard I was using and try to find some larger DIMMs for that setup. I really don’t want to go that route because I saw a definite improvement in playback with the Intel setup. I had far less pixelation in the recordings and live TV.
