How many test pass is needed/recommended to conclude that a RAM kit is 100% without errors?
post #2 of 15
1 pass is usually fine for most purposes, but if you want to be 100% sure let it run overnight for 6-8 hours.

At stock speed, 1 or 2 passes is fine with me. Some people go all out and test it for 24h, but I think that's way overkill

Sooo, you eventually went for the G-Skill 1200's eh? Nice!

Oh alright, lol..

Acoma, I'm still learning how to overclock RAMs but for now how can I run my G.Skill PI 1200 to be running at 1200 with the UD3P? It's running at 1066MHz only as we speak.
post #5 of 15
The easiest way to run 1200mhz with the UD3P is to run 450 FSB and then use the 2.66 memory multiplier. You could turn down the CPU multiplier to make the clock speed lower if you want. For example you could run 450 x 7 = 3.15Ghz. Shouldn't be too hard for the Q6600.

Oh, it's better to run them one at a time?

You would save yourself a lot of time by just testing them all at once. Only if you encounter errors you should test them seperatly to see which is the bad stick.

google MCH strapping if you havent looked it up already.

you could try 400mhz FSB. the highest MCH strap on ur board should be 400mhz, thats what it is on my UD3R. using FSBs that match those listed as the straps makes it easier to reach common RAM speeds. my FSB is 333 and i have the 3.2B multiplier for 1066mhz RAM. i had to mess with this a lot when i was trying to get my OC setup. just set the highest FSB you can get that matches a MCH strap (most likely 400mhz) and then raise your multiplier till it becomes unstable, then knock it back down .5x and stress test there. if its still unstable, knock it down again. this is a very simple way to do it, maybe not the most refined, but its an easy way to get a good OC and have RAM speeds that can match stock speeds. you can go with another MCH strap, like the 3.0 strap in the 400mhz catagory for 1200mhz on ur RAM speed. there is also a 3.33 or 4.0 strap, i forget which, but those are probably too high for your ram to be stable

it will take some getting used to. if you do use 400mhz, you will need a higher multi to reach the same CPU speed you want, but 400x9 = 3600mhz, a good OC.

Ahh.. But why doesn't the board natively support 1200MHz?
