LLC In Simple Terms ?

[paulselhi]

I have searched and searched but cannot find a simple straightforward explantion of this

Basically i need to know what are the benefits/ non benefits of usng it
Is it better for the CPU or possibley harmfull
Does enabling LLC allow for lower cpu volatges or do we need higher voltages

Any explanations in terms that a muppet like me can understand would be welcome

So the "former" intel method is with LLC off and would require a higher fixed cpu voltage in the BIOS? does this mean that cpu voltages would fluctaute but as a high cpu voltage is used the o/c can handle it and with LLC we use a lower cpu v but llc does the fluctuating to compensate?

My 4.2 Ghz o/c on a 930 seems to want LLC at level 2 ( gax58a-ud3r) im am using 21 x 200

Is a level 2 llc bad for the cpu/MB ? my cpu v is at 1.38125 and my cpu vtt is 1.375

should i try for stability with LLC off (standard) and raise my vcore ?

I can only seem to get a 4Ghz o/c stable at 1.4 Cpu in BIOS. CPU-Z shows this as 1.360 v

The difference between 4 and 4.2 ghz is slight for my rendering needs what i am concerned about is getting a stable o/c that will not damage the cpu or MB when rendering for 48 hours at 100 % cpu. ATM my my tmps on the 4.2 Ghz are 70 C when rendering and is using a lower cpu volatage so that looks better than the 4 ghz o/c

I note in the gigabyte manual that it says the enabling LLC may cause longterm damage to the cpu/mb so i will not use it !!
This means i will stick with my 4.0 Ghz o/c LLC off as opposed to my stable 4.2 Ghz o/c LLC on

Now i, like other, folowed the gigabtye "official" overclock tutorial to get 4.0 ghz stable and also like others have found that need at least 1.4 CPU v in Bios it is not stable with anything less, shows as 1.360 v in cpu-z. It is however rock stable and i have rendered for 18 hours at 100 % cpu with temps at around 64 C

Can i relax now and enjoy the cpu as temps are fine at 65 c or less on 100 % load, or is this voltage just too much ?

If the voltage is too much are there ways to lower it and compensate in other areas (without uing LLC !)

Oh a bit of adivce to newbies like me, use a PS2 keyboard for testing as windows crashes wil not allow a USB keyboard to avoid the lenghty windows repair process

Thing is those sites get very techy about it and just don't simply say whether it is best to have LLC ON or OFF i am going with OFF as per the warning in the MB manual

 

[paulselhi]

Lets say for arguments sake i an get 4.2 Ghz stable and at 70- 75 c temps using 1.5 v cpu LLC off would this likely damage the cpu?

saying that i see on intel site that for the i7 930 VID Voltage Range 0.800V-1.375V i am running at 1.4 in bios 1.36 in cpu-z

Is there a way to lower the cpu v in bios and up something else to regain stability as it is only stable at 1.4 V bios
