Forcing x21 multiplier on i7 920?

[AD-15]

hello,

I've seen accounts on the 'net of people being able to "force" a 21x multiplier on the i7 920, using their Rampage GENE/P6T motherboards.

I understand that it is possible to use Intel's Turbo Boost to 'temporarily', under load, to increase the multiplier to 21 on 1 or 2 cores, but this is the first time I've heard of being able to have a 'permanent' x21 multiplier on all 4 cores without using Turbo Boost.

What other boards can do this?

Also, will it be possible to reach a x22 multiplier using Turbo Boost?

No, 21x is the highest I'm afraid.

No idea how to force it other than by using turbo boost and putting the CPU under load, sorry.....

you manually set the multi to 21, its as simple as that on my rampageII mobo.

Gonzo, you have a 940 though, so that's irrelevant for 920 (unless you have experience of that chip)

[GoNz0]

its the same chip apart from the 940 having a multi of 22 and 23 on turbo.

so its very relevant as the overclocking tips apply just the same as a 920 and all the I7 chips that are out at the moment, even the EE versions.

and the gene boards a scaled down R2E, i think you can still set the multi to the max thanks to BIOS revisions.

[GSte]

So you can set your multi to 23?

I can't set it to 21 on my P6T Deluxe but my BIOS is a couple of revisions old, will look into this.

[GoNz0]

yeh i can, i think you have to set the BIOS to manual overclocking and disable turbo mode then it should allow a manual multi of 21, you may be as well digging round the asus forum for your mobo ?

I currently use a 21 multi on my P6T SE and 920 D0, 170 x 21 for 3.6GHz

Yeah gonzo, but we always knew taht the 940 went to 21 multi, the question is does the 920...

i thought i had explained it with enough information for you to understand, but maybe not

you use the 920 overvclocking guide for a 940 but using common sence you know that you can add another 2 onto the multi hence me running a 23 multi.

understand yet ?

i did edit out what may be deemed as sarcastic in my original reply to you saying that my system spec has nothing to do with this as i was answering the OP's question as i knew the answer. so lets leave it at that ok ?

[nibbler]

Hey, I'm not being agressive...

[GoNz0]

maybe not but you were barking up the wrong tree

[nibbler]

nvm, but I assume you have specific experience with the 920 then?

[GSte]

It doesn't really matter tbh, if you can force a 23x multi on a 940 you'll be able to force 21x on a 920. I'll give it a go later though and report back, just to clear it up..... DDY says it works though, so it must.
