I am so jealous, my motherboard sucks, even though I have a water loop I can't get over 4.3 with any amount of voltage

hey all, this is my first post and i come with a problem:(
i am running 3820 with a rIVe, and the problem is that i just can't get multi to go up. i set everything in bios, and when the system boots up, it is still on 36.
also, a few months ago, i've managed to get it to 38.
am i doing something wrong? any ideas?

Set the turbo ratio, not the base ratio. The 3820 is locked so you will not be able to change the base 36x multi.

As for myself, I'm having a great time playing with this CPU. I need to get some different RAM, the corsair LP 1.35v stuff is a nightmare for overclocking and currently keeping me where I'm at. I found out because if I drop the speed to 1066mhz (closer to 1100 using the 1.25 boot strap) I can go all the way up to 5ghz with no issues without passing my self-imposed 1.400v limit. This is the best I can do with the RAM at 1333mhz, although I have not had a problem tightening the timings only frequency seems to bother it. Once I get some different RAM I'm shooting for 5.0ghz 24/7 stable.

Sorry, I don't understand when you said "will not be able to change the base 36x multi". Doesn't 3820 have limited unlocked multiplier, where you can up the multi to 44 (but CPU-Z only reported x43)?

The base multiplier is locked (aka the "normal" speed), the turbo multiplier has a limit of 43x (the Intel Turbo boost speed). The BIOS will allow you to attempt to change both, but it will only save changes to the turbo multiplier with the 3820. If you're attempting to edit the wrong multiplier field you will end up with a situation where you put the number in and it just changes itself back. Some boards have the BIOS displayed differently but on Asus boards like the one he was asking about it does show both.

Doesn't other SB-E, let say, 3930K when overclock also involved changing the turbo multiplier? i7-3820 on normal/stock frequency have turbo multiplier of x38, not x43. Because 3820 have limited unlocked multiplier, that's why we can overclocked to x43 multiplier.

Yes, but you can also lock the base multiplier to x amount and shut of EIST so it acts like a non-turbo CPU. My whole point was he may have been trying to change the multiplier in the wrong box and that might be what was causing it not to be reported once he got into windows.
