post #6511 of 14772
As said above 0602 patches current sensing so high levels of OCP do not need to be set.
post #6512 of 14772
So what would your suggestion for very high Overclocks @ 4.7 or 4.8 !! As of the moment i run my bios setting @ 180% for these OC's!

Bearing in mind the 2 above are for competing on the HWbot with high demanding Benchmarks.

At 4.2 i run mine @ 140% as this is my everyday setting!

Respectfully,

AJ.

Updating to 0602 worked for me.

Thanks for the help Raja.

Before I answer, may I ask why you feel it needs to be adjusted at all? My response will be based on what your understanding of the OCP setting is.

I run this 4960X@4.8 with 1.376V (under load) via offset, idles @ 0.864V. Is leaving cpu current on Auto "okay" on 0602 (flashed a couple of days ago). Is there a risk with it set @ auto?

OCP setting is marked with red color when it is larger than 140%. I guess red means dangerous or harmful to CPU?
post #6518 of 14772
I think some people are confused about what OCP is.

Think of OCP like a re-settable fuse. If you use a bigger fuse it will simply pass more current before it trips. Under normal operation, the current is not forced into the CPU; the CPU draws what it needs. For instance, if OCP is set to a value that shuts off at 120amps, but the CPU needs 140 amps, the VRM will shutdown as soon as the current draw exceeds 120 amps for more than a few micro-seconds. The higher you set the OCP the more current the VRM can supply the CPU if the CPU needs it.


So why have OCP at all? OCP is in place to prevent the VRM from supplying all of its current in a fault event. Just as fuses break a circuit. There are instances where one could set a threshold to prevent "more" damage. It won't stop the CPU from dying if something goes short in the die, but it may stop the board traces or related VRM components from burning up due to an open load.

Red at 140% is actually default on Auto BTW.

We have reason to feel confused as there is no detailed explanation or definition for each and every settings in BIOS or in manual.
Although there are some strings to describe these settings, but they are totally useless. I recall these strings were already improved several times in recent new R4E BIOS build, but still they are completely useless.
This is how OCP is described in manual:
this item provides wider total power range for overclocking. A higher value brings a wider total power range and extends the overclocking frequency range simultaneously.

I don't find too much information regarding how to change the OCP setting for my OC.

There is plenty room left in that help string area, could you try to explain each setting in more detail for future improvement. Thanks a lot.
