Memtest errors. Please Help

I have the Asus P5Q-Pro motherboard P45 chipset. When I tested both of my rams together Patriot Viper DDR2 1066 my computer crashed. When I tested them individualy I would get errors on both memory sticks at the same spot in every slot. So thinking both my memories were bad I decied to use my G. Skill ram from my other machine which pasted memtest on that machine. Exact same thing happened. My question is that these two memory modules are not on Asus' memory supported list for this board. Is that true and get this. My computer dose seem stable operating so I'm wondering if this is a problem I can probally ignore. By the way the error I got was contagouse at around 11-18% on test 3.

Thank you for your help.

  1. What timings and voltage are you using? What are the specs of your modules (JEDEC and EPP)?
  2. 2.1v 5-5-515 timings and this is my memory.
  3. Use CPU-Z and select the SPD tab to display the specs. The modules should work at the JEDEC 800 Mhz timings and voltage. If they don't, then you have incompatible or bad memory. I have a P5Q Deluxe and a GA-EP45-UD3P (both P45 chipset) and my G.Skill 800 Mhz modules work fine at 4-4-4-12 and 1.8V.
  4. it's EPP for DDR2 1066. And I did try that already. But not at 4-4-412 but 5-5-5-12
  5. Do they work at the JEDEC 400 Mhz specs? If not, then get rid of those modules.
  6. Scratch that out. as soon as I get money I'm goin after these. And I'll put The patriots in my lan party machine and run it at DDR2 800.
  7. Make sure they are certified for your motherboard.
  8. they are I checked the manual. But first I want a fan speed controler.
