what board do you have?

a 200bclk will give you 4.2ghz assuming you have the multi at 21.
I would try x6 for memory multi.

I've got the evga x58.

I turned turbo mode off so it would be 4GHz. I'll try 6x multi and let you know what happens.

EDIT: 6x multi didn't work either. I even tried loosening the timings on my ram to 9-9-9-24. Tried bumping up the vcore a little to no avail. I'm really frustrated that I can't even get it to boot at 4GHz. I don't understand

[Hefemeister]

there is some good information here.

Set your MCH Strap to 1600

Well...tried pushing my overclock again. These are the results.



Best I can do...unless you count safe mode, haha.



Stock cooler is really the only thing holding me back right now.

[Slaymate]

I'm pretty sure I can still go faster
And here's a little more of my Desktop

[hikaricloud]

Ouch, by .003s...nice.

[Hefemeister]

Thanks for giving me 24 hours Slaymate.

With the vcore you are running you have some headroom no doubt.

There is no difference between the D0 and C0.

Is this some kind of Desktop striptease? Keep showing us better times and a little more of the desktop?

Nice time.

[tastegw]

wow to both hikaricloud and Slaymate

to hikaricloud:

3.9 on stock cooling with a 720......simply pro yo!

to Slaymate:
im shipping you my i7, OC it to 4.5.....get-er-done!

[hikaricloud]

Thanks taste.

It just goes to show that the only thing holding me back was temps. Before I moved, 3.888ghz was my barrier...that apartment was really warm all the time. Here, it's alright to leave the place colder, and opening the windows makes for a HUGE drop in temps, sometimes around 10c. So with that extra little headroom, I pushed 3.9 with the multiplier alone, no tweaks.the 3.939 in safe mode as actually an accident, I was so confused when I saw it. Lol.

As soon as I pick up a new HSF, I'm breaking 4ghz.
