Who is the culprit - CPU, Mobo or Ram ???

[tornadog]

in my ongoing investigation to find the maximum stable o/c on my venice 3000+, I find that my cpu is able to do 300 x 9 = 2700 Mhz(12 hrs Prime stable), my Corsair VS memory can get to 210 Mhz or DDR420. Now when I combine both the system refuses to boot up. The optimal midway point I found was 253 x 9 and Ram at 210 Mhz or 300 x 9 and Ram at 150 Mhz. Why does my Ram refuse to run any higher? Can somebody shed some light on this mystery?

Try running the ram at 2T if you are using 1T or 1T is you are using 2T.

You may have a bum memory controller. Out of your two stable options, I'd choose 300x9 w/150mhz mem over 253x9 210mhz mem. Just tighten your timings at 150mhz for your memory. You should be able to go pretty darn low.

I see that you are using the 5/6 (166) and 1/2 (100) RAM dividers. Have you tried the 2/3 (133) divider? At 300MHz that should put your RAM at 200.

Avalon--

I have a similar problem with my Venice 3000+; I've got fantastic OCZ PC3700 Gold and I can't even run it at stock speeds (233 2.5-3-3-7) when I'm overclocked at 270x9. It's very frustrating--I'm getting a new PSU soon, but do you think it could be the memory controller?
