I need some help with my OC....

Right now I am running 2 Corsair dominator DDR2 PC8500 (1066) in my machine and when I did a check with CPU-z (after setting the ram to their stock values) it says my ram is in a 3:4 ratio. Also, I did an ITB just for giggles and my machine comes out unstable, which is odd concidering the fact that when I am running my reapers, they run just fine and there is not stability problem....

What do you think?

Do the reapers work at the same settings that the corsair is at now?

Not really, they do not like 1066, so i run them at stock (800) and they work fine.

So you are running the Corsair's at 1066, but you were running the Reapers at 800? Your ratio changed because the speed of the RAM changed. Your stability changed because your RAM changed. This is to be expected when you change components like you did.

I am curious did the amount of RAM change too?

I went from 4GB to 2GB... Is that bad? I heard that the smaller ram amounts allows for better overclocking.

Did you manually set the vdimm to the manf specs?

You might need a little more volts to your NB. I am using OCZ Dual Channel Platinum 2x2048mb PC8500 DDR2 when I set it to stock speed it started it lost stability at first. Then I manually set my vdimm to stock 2.1v and set the NB volts to 1.28v. This fixed it. I am also running 400x9 so I would assume we are running the same divider.

On a side note I noticed you have vista and ubuntu listed as your OS are you running dual boot?

Yep. Works like a charm
The new Ubuntu makes it so easy to dual boot it isn't even funny. Resize your partition (this for if windows is installed first) by using the shink tool in vista. Shrink C down about 50GB if you can spare it. Reboot and put disk in tray. Boot from disk. Install from disk and select the partition that is unformated in manual. Afterward you will be asked if you want to transfer your stuff from your profile on windows. your profile (or profiles) and click continue. Click install. It searches for filesystems and adds window automatically to grub

I have dual boot on my old pc. My new rig which is my OC rig is a little bit different. I have my main Hd which runs Ubuntu and I have a second smaller drive. I set this up tonight to run windows xp pro ultimate. It is not dual boot in the strictest since. I have to go into bios and tell it which drive to boot. I did this because I didn't want to lose any space on my main drive and I had an extra laying around. I want windows on a second drive so I can get my cpuz to validate. When I run cpuz through wine on ubuntu it has limited functionality.

What about your NB volts what are they set at?
