it's under the CPU features, i think it just enables the 21x multi.

Sounds to me like it's Intel's Turbo Mode then.

it is.

Set your power settings on vista from 5-100% to 100-100% and boom! a multi of 21 whenever you have turbo on...

Well that doesn't count then! The core operates at the multiplier of 20 the vast majority of the time, and 21 only occurs when some or all but one of the cores is/are idle.

no, if you go into the power settings and set the minimum to 100% then you get the 21 multi all the time. i get a 21 multi while folding.

Sorry, that's what I meant...
Anyhow, my overclock isn't stable at 20X 180 with any vcore below 1.388 (BSOD: "A clock interrupt was not recieved on a secondary processor within the allocated time interval")... Are there any other voltages or options to help an OC become stable without having to add so much Vcore?

you were right, i was saying no to him not you.

@core2duo
I am able to pick a 21 multiplier for my CPU ratio also with my MSI Eclipse. I can run the 21 multiplier all the time except when I am stressing the CPU. When I have 100% load on 5 threads or more (HT on) the multiplier jumps back down to 20. Now I said this before, but is it anything like what you have there and why don't you try to stress test it with Linx: http://www.xtremesystems.org/forums/...d.php?t=201670
Please try it and tell me if you get the same results as I am. I do not know why the multiplier drops down when under more stress. I do have the 21 multiplier all other times. I also have EIST disabled and Turbo mode Disabled in my BIOS. I can show pick if no one believes me about the 21 multiplier, since no one has freaking answered me about my questions.

I am able to get to 185-187 with a +0.120V CPU and +0.130V QPI to get to my 3.9 stable with the 21 multiplier. You are over "Intel's max rating" which is 1.375 I believe but you should try bringing up our QPI well as CPU voltage. Do not bring QPI over 1.35 though. But try to keep the QPI +0.01V over CPU. I would say you would be able to get to 3.8 or 3.9 with +0.180V on both CPU and QPI, which bring you to a core voltage of 1.372
