Hi all,
After I saw this result: http://hwbot.org/submission/2830783_0.0_cpu_frequency_core_i7_4700mq_4550_mhz , I got interested to replicate it with a similar method and decided to share my steps to score higher than a desktop 4.4ghz 4770k (according to cinebench
![wink.gif]()
) on my Clevo P150SM
Intel Stock microcode has a Turbo multiplier bin glitch that allows unlimited multiplier increase, I used prema's bios and removed a cpu microcode update to let the cpu run the stock glitched microcode.
1) Download or dump your BIOS, if your bios is ami (my case) then use AFUWINx64
2) Get AMI Aptio UEFI MMTool v5.0.0.7 and UEFITool, HxD (or your fav hex editor)
3) Open your BIOS image with UEFITool, then File>Search, in our case Haswell has the following ID:
Quote
C3 06 03
, enter C3 06 03 in Hex pattern dialog click OK
4) You can see the last four Hex pattern result, double click the first result and a structure item in the main dialog will be highlighted, right click>Extract as-is to a folder (be sure to be neat and organized or you will mess things up)
5) Do the same with the third result and save it as a diff name other than the first one
6) Now in the folder you have saved the 2 files from step 4&5, open the first one with HxD(any hex editor) and look for
Quote
C3 06 03
be sure to choose Datatype:Hex-values then hit search
7) Press F3 to find again till you reach this pattern(highlighted):
8) (1) Indicates the microcode version, 17 in this case, we want 00 (cpu stock), (2) the platform ID (the search context we reached at) (3) the microcode length = 5000 (in my case) in reverse (important to know when the microcode ends in order to remove).
9) Adjust the cursor on the beginning of the highlight text/microcode (01) right click>Select Block>Length>5000 or whatever in your case
10) Delete the highlighted blocks (after step 9) then save the file
11) Do the same with the second result from step 3 to 10 then save
12) go back to UEFITool, double click the first result like you did in step 4, right click the highlighted structure in the main dialogue > Replace as-is then choose the FIRST file you edited in HxD
13) Double click the third result and follow step 12 with the SECOND file you edited in HxD
14) You will see "Rebuild" in action row, File>Save image as> P15SM04.PM2 in my case (can be any name as long as your flashing tool recognize it)
15) Open AMI Aptio MMTool > Load Image > your modified rom > CPU Patch Tab and verify there is no 06C3 in CPU ID
16) Be brave and flash your BIOS

Windows Mod to remove auto update microcode on boot:
1) Remove mcupdate_GenuineIntel (and backup) from System32
2) Done
Overclocking:
1) Check CPU MCID
ownload AIDA64 , open AIDA64>Motherboard>CPUID and look at IA Brand ID, it should be 00h
2) Download the latest beta Throttlestop (not stable) in my case 810b2
3) Make sure you don't have XTU installed or running (especially at startup) or it will reset any changes in Throttlestop
4) Open throttlestop, click FIVR and look at "[checkbox] Overclock [DIALOG] Max" and note it down
5) Now here is the magic! close FIVR and open it again, [DIALOG] Max value should increase by 2 (up to 80x max ~ 8ghz) everytime you open and close FIVR aslong as long as you increase one of the cores, (bin recursion on msr15, you can't set this outside throttlestop if you can't read max turbo possible by the cpu itself everytime)
6) Increase "Set multiplier" to maximum after your final changes in FVIR (Iv set mine to 42x all cores, so I increased set multiplier to 42 aswell - note voltage ID is messed up ignore it)
7) Increase voltage in FVIR for stability by using cinebench run 3 times instead of prime95, as it stresses FPU which increases heat and tdp instead...
8) Unlock maximum TDP and turbo wattage in TPL, in my case:
9) Done! Changes should be persistent as long as you dont save and exit from BIOS, here is my result in Cinebench with temp throttling (from 4.3 to 3.9 ghz), room temp 25-27 XD: (no.1 at 4.2ghz, no.7 stock latest microcode)
UPDATE: OCed RAM from 1600 to 1866, [email protected], +200mV adaptive vcore:
I'm also getting 852 with 4.5ghz, t̶h̶o̶u̶g̶h̶ ̶i̶t̶s̶ ̶u̶n̶s̶t̶a̶b̶l̶e̶ ̶a̶s̶ ̶t̶h̶e̶ ̶f̶r̶e̶q̶u̶e̶n̶c̶y̶ ̶s̶c̶a̶l̶e̶s̶ ̶d̶o̶w̶n̶,̶ ̶(̶m̶a̶y̶b̶e̶ ̶d̶u̶e̶ ̶t̶o̶ ̶h̶i̶g̶h̶ ̶v̶o̶l̶t̶a̶g̶e̶)̶
Static voltage table like on load method using TS:
Post your results and I'll copy it here.
Tips:
-I highly recommend lapping heatsink and use liquid metal thermal paste or any decent tp ( I used collaboratory liquid ultra) before doing this.
-If your cpu throttles no matter what, try decreasing dynamic voltage in FVIR and look at maximum value the package power indicate while stressing, decrease the value by 10% in order to avoid rapid throttling (happens with bad TP)

-Do not attempt the OC if you are looking after long service life wear&tear (I expect 2 years from now if I stress the cpu everyday for an hour, which i never do
![tongue.gif]()
)
Happy overclocking, and don't melt your laptop
Thanks to Intel if they leaked this on purpose, kinda futureproofed my machine XD
Updates:
-Tested on desktop i5 4430 without altering reference clock, OCable 3.2 to 3.6ghz max (high voltage monster cpu
![biggrin.gif]()
.just look at the stock TDP : 84 W)
-To add:(This has been done by Asus with desktop on haswell launch aswell, though BIOS updates were pushed asap, steps should be similiar with desktop mobos, there is a decent advantage of applying this on non-extreme mobile due to the insane cost. getting a K processor with desktops is a wiser choice for cheap extra
-Intel has done the same mistake again with Skylake this time, would be interesting to see how far 6700HQ can go.

(Thank you MOD for finally removing the useless posts, funny PM example: "aj****** sent you this private message on http://Overclock.net , April 17, 6:46 pm
if your UEFI/BIOS has the settings in it, you really should set them there and not in XTU. XTU is ****! Meanwhile, have you tried the mod on the locked Xeons on this architecture? That is where things start getting interesting. Meanwhile, you come off as a complete a**, TBH.") Just to clarify, only Throttlestop works with the OC, since in my case, XTU/BIOS does not read the [secret]MSR register, as reading it increments max bin with mc
