Sounds like you also may need to test for stability, with something like Prime95 or other stress tests for several hours, you may need to adjust voltages a little.

Agree.

Two questions worth running by you.

1. I have a v4 Xeon - any idea whether core unlock is available on it, or does the mod only apply to v3?

I've got two of these:

Intel QK3S (E5-1660 v4)
8 Cores @ 3.2 GHz; 20MB L3 Cache

2. Also, I assume there's no way to uncap the core ratio - is that right? BIOS locks mine to 36x, which I believe is the highest 1C ratio (but your mod applies the ratio to all 8C).

This is all fascinating, and you are a genius.

@oddworld - on V4' I am not sure, you'll have to read over at the huge Anandtech thread and see what they've said about V4 there.
Same for max ratio, I think they discuss this there, I don't think there is a way to push it past the Intel locked max, but it's possible maybe they've found a way to do 1-2 bins past there, I am not sure.
Sorry, I have never had X99 board, and have never kept up with this mod, and am only rarely asked to help with it, so I know very little about it

Thanks. I agree with your impressions. Just wanted to make sure I was not leaving core multipliers on the table.

@oddworld - From your testing, and your reading on this subject, do you think for sure this has worked, and that not all cores are supposed to hit/stay at max, or is this supposed to cause all cores to be at max always?
Did you set #3 from this guide to 32, that makes it sound like all would be 32 always. Is that how this is described, and shown in others benchmarking results when you look around at others discussions on this?

Yes - I think it works great. My CPU max ratio is 36x. It holds that indefinitely unless there's power max issues (such as P95). Normal applications, like gaming, hold 36x without throttle. I have not yet played with BCLK or core voltages.

My understanding was that BCLK is a tricky bitch that has a tendency to throw the whole system into a wacky state (without much benefit on xeons).

Thanks for your thoughts and confirmation. I asked because user here says still not unlocked all cores - X99Z V102 Inserted .FFS driver doesn't work
And in your benchmark, I noticed not all cores hit max either, but looking back at image on post #6 I see they are all hitting x36. So I must have had your thread/results confused with another post/thread or something, someone posted results I remember only one core hitting 34 and rest staying at 32 I think
Bclk is same for standard CPU and XEON, they are same/same in this regard, if Bclk is not worth the hassle on X99 then it applies to all CPU Xeon and Normal Desktop CPU

Hi , I have Intel Xeon E5 - 2698 V4 ES QHUZ proc. Can help me with modded bios for ASUS X99-E WS or HP Z440 motherboards. Thanks Vengaiah

I am ok to pay for the services

Hi , Can someone throw some light on this

You have a v4 CPU. Hacking bios methods for v3 don't carry over to v4. It's also 100% outside my area of expertise - so I'm no help to you. I would recommend making a new post, similar to what I did.

Hi, Thanks for reply
