Bah, nothing's wrong with LLC on this board.

Basically, the 45nm processors seem to be a bit more...fragile than their 65nm predecessors. What this means is that if you enable LLC, you will be receiving a consistent amount of power (whatever you set it to in the BIOS). This is great for stability, but can be bad for more fragile chips because over volts can occur when the processor is under load. You'll probably be fine, but there is a much greater risk of you breaking something than someone with a 64nm chip.

I concur, after being speculative about LLC and IMHO a shotty cheaply made mobo
that a particular review site happened to blow out chips on.

I conclude for myself and clients , that LLC on these UD3 boards is more than fine
in fact it does not spike @ all ever, which was what killed some 45nm chips idle in another brands boards. That company jumped the shark as far as Im concerned.
Also using aluminum in th pcb instead of copper ?? hmm
Gigabyte used double the copper they normally do , so something does not jive.

I have been testing this for a few and at waay higher voltages and OCs than Anand
up into the 4800 1.48 v range and no problems.

Im sure I have ran my system longer on 1.48 v than they had the whole test rig together
and blew out 3 chips. Its not LLC its poor craftsmanship

Any of you guys have had the need to bump the MCH vcore in order to acheive 400 FSB? I cant seem to really reach above 390 without having to tweak some settings, and no necessarily the voltage of the MCH because no matter how high i set it (only gone up to 1.4) is still doesn't boot! I also tried to mess with the PLL and term voltages but no luck. Thanks ahead!

I was able to hit 400 without much hassle. I just bumped the vcore to 1.41 and changed my multi to 8. This gave me 3.2ghz with pretty much the same hardware you have on your sig rig. The only difference is the ram, which I have running at a 1:1 ratio at 800mhz.

man i guess my board has something going on in her mind.. i was only able to hit 390 and nothing else above that no matter how much MCH voltage i add.

Actually the LLC issues take place during idle not load.

It does seem that this board has resolved it though. I ran power monitoring both idle and load and the spikes present with the Asus boards capable of doing LLC do not seem to be present.

I personally cooked a highly overclocked E8400 on an Asus board through the direct use of LLC a few months ago (it fried while the system was idled and I was unlucky enough to see it happen while running a monitoring app).

My thoughts on LLC in general are changing after putting this board through its paces.
