Starting off with a basic guide of relating to the 5960X on ASUS motherboards:

I am trying to find the highest value for my 24/7 running. I have booted in at 4.5 and 4.6Ghz
I am currently running 4.5ghz at 1.307v with out any problems and my temps are 34-38c at idle.
I can run any thing I want without issue. I want to keep the temps down, to not degrade the chip.
However when I try to run ROG RealBench 2.2 It starts up then blue screens. Do you think this is a major concern? Should I be reducing until I can run the test? Please give me some feed back.
Thanks.

Where is the CPU Input Voltage in the BIOS please?

Can't find it 😞

Have you checked chapter 3 of your motherboard manual? It should be listed in there.

Can someone help me.
I just finished building my computer and it was running OK for a couple of days with an 4.2 overclock at 1.25vcore and the memory at 2666. I passing realbench with no problems, but last day i tried again realbench and I couldnt finish not even 15 min without a restart, not even a BSOD just a restart. I cleared CMOS and I tried at stock settings realbench but its happening the same just restarting no BSOD or overclock fail. Even on stock settings I tried raising the system agent voltage and same thing.Now i will try to flash the new bios 1801 and see, it was on 1601. If somebody have an ideea please help. Sorry for my english.

Both motherboards are good overclockers. It's just that the Rampage V Extreme is more oriented to extreme overclocking crowd. With the Rampage V Extreme, you get a few more options when overclocking and a lot of extra features like the Retry button or the OC Panel, etc...

Ok thank you Chino

Proper VCCIN voltage is dependant on several settings such as CPU speed and voltage, cache speed and voltage and to a lesser extent SA and IO voltages. Though DRAM voltage is external to the processor the amount of installed ram, speed and timings can also have an influence on the needed VCCIN voltage because of loading.

The following is assuming active cooling across the VRM section of the motherboard. Set VCCIN to 1.90V and LLC to Level 8. Make the necessary adjustments for stability at your desired CPU, cache and memory speeds and timings. Once stability is found slightly lower VCORE and increase VCCIN in 0.010V steps. If still stable continue lowering VCORE, raising VCCIN and testing for stability until VCORE cannot be lowered any further while remaining stable or 1.95V VCCIN is reached.

If increasing VCCIN from 1.90V does not allow a lower VCORE VCCIN may already be higher than needed. Lower VCCIN in 0.010V steps while testing for stability. Once instability is reached increase VCCIN at least 0.010V.

Setting LLC to Level 8 pretty much locks the VCCIN voltage to the same value regardless of load. There is at times an approximate 0.020V droop but the droop and recovery happens quick enough that it is likely not to be seen by software. If the VCCIN voltage is at a low enough value LLC levels from 5 to 7 can be used. The lower the LLC level is the more voltage droop will increase. Moving from LLC Level 8 to a lower setting will require increasing the VCCIN voltage. Keep in mind that droop is a good thing as it helps guard against overshoot during loading. But the amount of droop needs to be balanced against the required set VCCIN voltage.

Thanks PRAZ for that info, things like that and well explain is what we need in this forum and have them post @ the sticky section for other to find easy. I just have you add it to my MENTOR's list, beside VIZ also, that I haven't seen him around also Blade. But some one need to make a good and well explain guide about OC this board like for my self I'm new in this type of board, and as my signature stay look for a good MENTOR, thx PRAZ.

Thanks for this explanation although I do not quite understand some technical terms (English and me...)

With an LLC to 8 and VCCIN to 1.85v, in idle and load is 1.856v (no vdropp)
With the LLC to 7, idle at 1.856v and load at 1.82v

It is better to leave the LLC to 7 or with to 8, it's ok?
Or let to 8 and increase of 0.010v (or 0.020v) the VCCIN?

Thanks 🙂

Very helpful advise. Thank you. I managed to decrease my core by another 0.04 at LLC 6. This also seemed to have general an *mpact on my system performance.*:cool:
