You can't change multipliers on that chip. It's locked. The only thing you can do is take your bios, remove microcode from that bios for haswell chips, and use one of the efi drivers in this thread to unlock full turbo speed for all cores. you will also need to remove microcode from windows and use vmware's microcode installer and install one of the earlier haswell microcode version 1F or 39. For overclocking you can only do BCLK overclocking which will be limited by the motherboard's capabilities. I've seen people go as high as 10% overclocking but I haven't been able to get past 6% oc.Hello i have a ES E5 2650 v3 on a asrock extreme 3 that i can't change the multiplier on do you guys know how to make it do that ?
Thank you for the tip. I did look at window's event logs and noticed DCOM errors which I followed this guide to stop it from happening. http://www.tomshardware.com/faq/id-3128597/windows-error-10016.html seems that I haven't experience mouse lag yet. I will keep looking though as I know you're right about bclk overclocking messing with PCI and USB controllers. I used to have issues with my USB 3 ports where I couldn't transfer any files from or to my thumb drive.BCLK overclocking can sometimes cause problems with PCI devices and USB controllers that are intermittent and hard to diagnose. You might be seeing that. If you're running windows, take a stroll through the event logs and look for system items for unexpected errors.
witch EFI driver should i use ? and how do i remove Microcode for haswell btw im a noob at this stuffYou can't change multipliers on that chip. It's locked.

https://vk.com/topic-70826500_34866008?post=2694Hi friends! Can you share to me your bios for unlock ASRock Fatal1ty X99M Killer/3.1? I just can not find it ...
my email liveaswant@ya.ru, thx

My computer keeps crashing randomly expecial in idle or light use! Is that more microcode or power saving issue? It is not depending on voltage offset.
I have feeling it is depending intel microcode 3c / 3d that is loaded on os level.
ENABLE C3
DISABLE C6
Thanks for helping!
I Have now these settings:
CPU C State >>> Enable
Enhanced C1 State >>> Enable
CPU C3 Report >>> Enable
CPU C6 Report >>> Disable
Package C State limit >>> C2 State [ Auto / C0/C1 state / C2 state / C6(non Retention) state / C6(Retention) state ]
It is working now
Does anybody even now know what is Haswell-E SFR Adjust?
Can anyone help me please to remove the microcode from the latest bios unfortunately I don't have the know how

What is the main reason bottlenecking current flow in these turbos? It is mobos software or hardware limit or CPU hardware limit? I can reach 18x3300Mhz quite easily but that is feeling lika a hard limit for my system.
EDP, electrical design point (CPU hardlimit). There are many suggestions for a workaround (mostly by me in previous posts), but no one managed to succeed one so far. I guess mostly it is just too time consuming and unpredictable in the harm to the hardware. An EDP exist for a reason, you know ?
Mostly at the state I am interested in a sandsifter log of an actual Xeon E5 v3. No one published one so far, yet.
Both C3 and C6 (and their package state limits) are broken. Both should be disabled and can lead to a lockup. You can read about it in the Intel Whitepapers.

See HSE20, HSE 25 and HSE49 (without C3 no re-entering of C1E).
All three I can observe if I have any C state activated except C1E. As you can see in the revision history, there never came a fix (like with almost all their CPUs).
