Ok - this is one solution to reach 4 GHz with 875k.

It's also possible to disable K-Boost, set Multi to 30, Enable Turbo and Speedstep an set the Offset core ratio to 0 0 0 0 (not disable, must be enabled).
Turbo must be enabled when using K-CPUs (or you can't use a multi higher than 22)
 
What I still missed is the powersaving... that was the reason, why I decided to upgrade vom 860 to 875k. 
C-States C6 works.. or not? I don't know.. can't see anything in windows about that.
Speedstep works, of course, but 1,32Vcc while 9x133 = 1200 MHz is needless .. it's always 1.32Vcc -.. with 1,2 GHz or with 4 GHz.
With C1E my vcore jumps to dangerous values.. it's out of control - from 1,3V in BIOS it boosts up to 1,52V.
So in my opinion.. it has to be disabled.
 
And.. if you clock with the multi (K-CPUs), normally you don't need to increase VTT. VTT is at stock ... in my system at 1.04V.
VTT needs to increased, when pushing the BLCK. 
Only Vcore is necessary.. 
 
I'm still waiting to see "oc the K-CPUs the right way" by the EVGA Team (see the video from Jacob)
Please EVGA post a overclocking guide for the K-CPUs!!!
I'm using BIOS A72.
So many users here change their MoBo from EVGA to ASUS.. and now, they are happy.
I don't want that!!!

Anytime pugboy75
 
I totally agree with dozer3000 we need the power saving features fixed there is no reason for evga a premier overclocking specialist community/company to fall behind asus in quality overclocking products.

Hi,
I just got my motherboard the other week. I tried to install the updated version of bios in windows 7 64 bit but its not going through, after pressing capital Y hit enter, the black window automatically closes. Does this means the bios is already updated? because I cannot find any option where I can disable the start up process of the board if its correct the "clock gen" to be disabled, every time I turn on my PC, it will shut first then start again. Hoping for your help, thanks.

@dozer3000, yes I did press "Y". :)

unzip it to a folder or somewhere before trying to use it.. if you dl it then try to run it without unzipping it it will close the box on you..

hi all,
 
just flashed A72 on my FTW and impossible to have multilier 22 without activate boost with a i5 760...it's a problem on oc,bclk and oc  is limited with boost activated...
 
is there a solution actually or perhaps in future ?  !!
 
thanks a lot !

BIOS 72 Updates:

• Now CPU multiplier can be adjusted with Turbo offset

---

CD/DVD Installation - Recommended installation method

• Download the correct .zip file below for your motherboard:

         160-LF-E659-KR - EVGA P55 Classified
        141-LF-E658-KR - EVGA P55 FTW 200
        132-LF-E657-KR - EVGA P55 FTW
        132-LF-E655-KR - EVGA P55
        123-LF-E653-KR - EVGA P55 LE
        121-LF-E652-KR - EVGA P55 Micro

• First go into your BIOS and load defaults, save and exit
• Go into the folder where you unzipped this package and run the appropriate batch file.
  • For Windows XP, Vista or 7 32Bit: AFUWIN32.BAT
  • For Windows XP, Vista or 7 64Bit: AFUWIN64.BAT
  • If in DOS Mode: AFUDOS.BAT
• Press Y in CAPITAL LETTERS to start the flash process
• DO NOT TURN OFF POWER OR RESET DURING THE FLASH PROCESS
• After the flashing is finished, shut down the computer. Then power on again and go into BIOS, Load Defaults, Save and Exit.

Warning:
**Do not restart or interrupt your PC while the flash is ongoing
**Do not Flash BIOS on overclocked settings
**It is always recommended to power-down after flash and Clear CMOS

 
 
 
do us all a favor for the love of god, MAKE BOOTABLE ISO BIOS UPDATES!!!!!!
if you cannot log into windows due to say the bios not picking up your memory corretly, then these stupid .zip files DO NOT WORK!! and the average user will never EVER figure out how to update the bios in their brand spanking new board.

I too got a new P55 micro board, my first "i" series setup, and I was really confused on how to update the BIOS. I had done it many times before with a CD, and thought I still had to do that. Your instructions need to be clearer, I wasted so much time figuring that "Oh! you just run it!"

solution... most of these have multiple BIOS... switch to BIOS 2 or 3. smile and wave.
 
i'm grateful that it's so simple. the last thing i want to do is sit around and make a bootable flash drive or ISOs, etc... wastes time/resources... clicking a .bat file is simple.

run it from an elevated command prompt.

I still can not update the BIOS even when running as admin. Any other ideas?

dl then extract it to desktop or folder first then open the one you need and run it with Y..

Should I be concerned if my pc is crashing randomly, i have the original bios on my 2nd mobo selector and A72 on my first mobo selector. i dont get random crashes with my 2nd bios.
I'm not completely sure which version it is at the moment that i have on my 2nd mobo selector.
I'm not OC'd and all my voltages are stock.

hi,
 
1) 4 GHz is easy, after 4 GHz it's going hotter, you'll need much more voltage on Vcore and / or VTT to get it stable.
2) try to use an safer RAM setting for the CPU clock test
3) this is nothing for the BIOS RELEASE Thread 
 
;)

SPACEGOAST, I had the same problem until I extracted the file to my desktop, then it worked.
 
 
When I use the "dummy overclock" I get blue screens before I even get to the desktop. Can I reflash to an older bios or could it be a voltage problem? I never updated my bios before and figured I'd try it, don't know much about overclocking but if ya think I could benifit from changing some voltage numbers let me know.  Have no idea what settings to use though.
 
I have the evga p55 sli board
 i7 860 cpu
8 gigs ddr3 @ 1600mhz
 
without overclocking the cpu runs at 2.8ghz, with teh dummy thing it goes to 3.3. I get 33 degrees C while surfing the web, during gaming it has never gone higher than 45c
