![]() ![]() MOD EDIT: link removed, please use a clean BIOS base because of legal implications with Intel : P150SM 1.03.05 modded bios (at your own risk): Thanks to Intel if they leaked this on purpose, kinda futureproofed my machine XD Happy overclocking, and don't melt your laptop 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 :P) 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) I highly recommend lapping heatsink and use liquid metal thermal paste or any decent tp ( I used collaboratory liquid ultra) before doing this Note: You can maintain maximum turbo multiplier bin with latest microcode after setting it in throttlestop (imp: no crash when testing make sure its stable) then flash the latest microcode for bug fixes (more stable on my side at x45 with only +230mv, depends on your CPU, i7-4800+ will require less voltage), and you will still be able to set the bin high (up to 80x) as long as you don't crash. ![]() I'm also getting 852 with 4.5ghz with this adaptive voltage-like method: UPDATE: OCed RAM from 1600 to 1866,, +200mV adaptive vcore: Type DEL mcupdate_GenuineIntel (and backup) Done!ġ) Check CPU MCID:Download AIDA64, open AIDA64>Motherboard>CPUID and look at IA Brand ID, it should be 00hĢ) Download the latest beta Throttlestop (not stable) in my case 810b2ģ) Make sure you don't have XTU installed or running (especially at startup) or it will reset any changes in ThrottlestopĤ) Open throttlestop, click FIVR and look at " Overclock Max" and note it downĥ) Now here is the magic! close FIVR and open it again, 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, LOLĦ) 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)ħ) 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.Ĩ) Unlock maximum TDP and turbo wattage in TPL, in my case:ĩ) 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) Now use the DEL command to delete the offending file. ![]() To change to the Windows\System32 directory you would enter the following command and Press Enter In the Command Prompt window and change to the directory where the file is located. Right-click on CMD and choose Run as Administrator Windows Mod to remove auto update microcode on boot: Be sure to choose Datatype:Hex-values then hit searchħ) Press F3 to find again till you reach this pattern(highlighted):Ĩ) (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).ĩ) Adjust the cursor on the beginning of the highlight text/microcode (01) right click>Select Block>Length>5000 or whatever in your caseġ0) Delete the highlighted blocks (after step 9) then save the fileġ1) Do the same with the second result from step 3 to 10 then saveġ2) 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 FIRSTfile you edited in HxDġ3) Double click the third result and follow step 12 with the SECOND file you edited in HxDġ4) 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)ġ5) Open AMI Aptio MMTool > Load Image > your modified rom > CPU Patch Tab and verify there is no 06C3 in CPU ID
