Dufus. Thx!@GTZ no ratio overclocking for that CPU so this bug will not unlock the i5 -4460 unless perhaps one can write microcode. Best that you can probably hope for is all cores at 3.4GHz if set with a microcode version of 0x7 or less.
@fromax legacy mode should not matter, try running the shell driver in test mode first and from there exit to W7 or are you already able to do that? If it's a case that you are successfully booting W7 but stuck with base clock then please post a CPUZ txt report. First time I ever heard of RU is when The Stilt posted it so he may be able to give a few pointers. The MSR settings are already noted in the thread, V3.EFI was just meant as a crude way to apply those settings.
@vadimkara my microcode is not removed but modified similar to post #101. If it's not posting with default settings (no OC / FIVR defaults) then perhaps that CPU / BIOS combo relies on something being fixed from the microcode. Do note for that CPU it will be microcode with CPUID 306f1? not 306f2.
@Soarer while waiting you could go through the steps fromax took to modify his BIOS and possibly try something similar.
Did you only use UBU to remove the uCode? - That happend to me as well. After that I used MMtool to remove the ucode, and then afterwards open it in UBU and just straight away save it (without any other modifications, just saving it).
1. Open bios in MMtool, remove ucode, save file/bios
2. Open saved file/bios in UBU, and save straight away (option 0 if I remember correctly) Don't do anything else.
3. Use the saved file/bios from UBU to flash.
Should solve the no-booting issue
Seems CPU 306F1 can cause post problems with no microcode update. IOW the method shown on this thread is unsuitable and modification would likely have to happen in the BIOS boot block.
Remember V3.EFI uses BIOS NVRAM to get called so resetting to BIOS defaults or CMOS reset can clear that so it will no longer be loaded at POST.
@Ionstream the hexedit method is a possible way to avoid changes to file length while keeping simple checksums in check. Since some of those executable pointers may be hard coded then changing positions of code in the region would likely cause failure to POST. Of course if other checks are at hand there is no guarantee of success. Your registers show that turbo ratio changing is supported and not locked out, so should be good to go.
@TheSellHard in CBR15 base clock is shown as 2.3GHz which normally would means 1. BCLK at 115MHz, 2. a timer bug or 3. an option for cTDP up. In the video the benchmark takes 20 seconds to complete and such a time would be indicative of a score of around 2025. 2330 should take a little under 17.5 seconds if my calculation is correct. It would appear the timer(s) is showing a 15% boost.
Nice results from you all and great work in helping each other.
Hey, I made a pack with all the tools necessary UBU, UEFI SHELL, V3 driver, microcodes, etc and instructions =)awesome man! can you please provide me the bios you used? I have an x99 deluxe and I want to do it too.
This is a fake result with timer hack or overclocked 15% bclk?Dufus. Thx!
I installed two processors alternately and 2683 2695. One of the runs of the system with 2683 showed me monstrous figures. Photos in instagram. I tried many times to replicate it but to no avail. How is this possible? It's not photoshop!!! Corona Render showed 5670000, CPU-Z 23700 and CB R15 2332!!! =) Tell me how this could happen ???
Result CB R15 - https://www.instagram.com/p/BQv2q-WgY7i/?taken-by=thesellhard
Thank You Dufus. You're the best ;-)@TheSellHard Sounds like an issue with Windows using the TSC (Time Stamp Counter) of the CPU as the performance clock and not updating properly after the swap, perhaps a fast boot issue.
Try setting Windows to use the High Precision Event Timer (HPET) instead by enabling it in BIOS if not already enabled and adding the BCDEdit option "useplatformclock yes".
From where you got them ? And how to get other microcode versions in .dat format ? I would like to try others.
Are you sure ? Afaik only the max limit is 240W, but the Power Limit 1 is already forced at 120W. In my Taichi board Ive the ability to change them, but the new values are not taken. The only settings which I can successfully change are Thermal Design Current and the time for Long Duration of Power Limit 1.All Haswell-EP HCC SKUs should be unlocked up to 240W.
Yeah, a small manual on programming MSR would be cool.What tools should i use, to programm MSR registers(maybe in small manual).
How you managed to get ratio of 29x ? Did you used Dufus v3.efi ? You reprogrammed MSR registers ? Or did you played with vcore or whatever ? Thanks for any clarification!My 2686v3 stayed at 2.9Mhz on all 18-core with the micro code 0x27. Is there any way to make 3.5Ghz in the 18-core?
What does these options do exactly ?
