[TUTORIAL] [4GHz+] Overclock i7 4XXXm(q/h) to i7 extreme conversion Intel Haswell CPU Microcode bug hack

Recommended Posts

Hi, I have mod the n750jv bios to v1 using  UBU_v1_65 and OC to 3.8-4Ghz using ThrottleStop 8.40. However, once reboot the multiplier falls back to 34 and I have to set it  again using ThrotteStop again. I haven't installed XTU. Any idea to make the multiplier persistence so that I can flash back the lastest MC? Also what is v00? UBU_v1_65 only has v1 to v21. Thanks in advance!.:angel:

Hi i saw this thread and decided id partake cuz i have a laptop with the same cpu i rehauled. It had a i3 but when i saw this i got a i7 4700mq 4 150$ and put it in with liquid metal 66c full load @3.6ghz all cores -90mv core. I also got a rx480 egpu im using with it and the cpu is being power limit throttled 24/7. My laptop is a toshiba satellite c55t-a5102.

 

My weakest link is cpu and i wanna adjust bclk and dump/edit bios but idk what software to use for my mobo as its a custom system and dont know what is locked down. Any advice or help will be deeply appreciated. I bought this cpu specifically 4 this thread so im dedicated balls to the wall we gun melt sum sht

Also i wanna mention some interesting info, the lower the offset voltage the higher your minimum clock will be too. -150mv= 3.1-3.6 -115=3.0-3.6. -90= 2.9-3.6. Ps, bios type is insyde bios

Guys I want to try it, I have an intel 4700MQ, is safe to do? 

 

Thnks!

It's interesting to see this thread.

 

My 4700MQ ES is able to clock up to 80x due to the really alpha version of microcode.

 

However, the CPU self is awful to OC. 35x @ 1.10v is already comsuming 60+ Watts.

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. I will share the bios file, use it at your own responsibility and if you know what you are doing.

 

Is it possible to OC in the BIOS with this stock microcode and enter OS (WIN7 / Linux) with the latest microcode?

 

Newer microcode contains critical security fix.

Ok guys I can do it from my bios? I have prema mod bios

After you flashed the modded BIOS file, yes, you can OC with this BIOS.

 

I'm using prema BIOS, too.

Works great on my y510p with 4700MQ. Bios 2.07.

Found my sweet spot with 3.7Ghz on all cores OC and no voltage offset. Power consumption is 50W when all cores stressed.

 

I was able to achieve 4.1Ghz on 2/4 cores stressed. which is plenty useful for playing single threaded games. I could go 4.1 all cores but it would fluctuate due to power throttling.

As for the cooling, Liquid metal did the trick with temps staying mid 70s.

Was able to hit 4.4Ghz with +230mV core and 0.05 Vccin. however, power throttling at 56-57W kept dropping frequencies back to 3.4Ghz so its kinda useless.

 

Anyways, ty for the guide. this is pretty much a free upgrade that matches my other 7700hq machine.

Hi. I really need some help. I am trying to this method on a desktop mobo to be able to get more performance from an i5 4590. The issue is that when I extract files 1 and 3 with Uefi Editor and proceed to use the HexEditor to modify them, it's completely different from what your screenshot shows and I am scared to screw things up and brick my motherboard and make my PC unusable ever again.

 

Here is the BIOS file that needs the mod to allow CPU overclocking: http://www.mediafire.com/file/z6ppd2lf4n8opq9/7817v67.rar/file

I hope someone can give me a hand.

Thanks!

Hey first of all i have a barebone from msi MS-1492. My bios version is american megatrends bios  E14921G6.30H , 05/08/2013 . I have a gtx 760m and i7-4700 mq.
Im having a problem with him because every time that i stress my cpu it doesn't cross the frequency base of 2.4... As soon as i stop stressing the cpu the frequency goes up to 3.2-3.4 GHZ. So if i see a movie or i play some games my cpu doesn't give my full speed. And even if its a question of temperature can't it at least give 3ghz? i think would make a diference while gamming... I saw this topic, and although its from years ago I would like to know what can i do to put my cpu giving a bit more not overclock it until 4ghz but stabelize it at 3hz at least?

Obs: What temps you managed to get with i7-4700mq runing at that speed < 4Ghz ?

Welcome to the world of CPU throttling and not able to reach advertised speeds. Now, there can be many reasons to throttle. You have not given any info or screenshot on what exactly is happening. Use cpu monitoring programs to figure it out (search, there are plenty of guides out there).

 

Lastly, if your CPU is throttling (which it is) and it cannot even run at stock turbo speeds, then this guide won't help you at all. 

 

PS. I have managed to to stay at 4.2 GHz at 90C (cinebench R15 with cooling mods). It is not worth it in my case as there are other throttling mechanisms (current limit) which reduces the speed independent of temperature/power. I use 36x for daily tasks/games (no throttle) and 42x only for benching.

For exemple this is before running bench https://ibb.co/FXS6Vwd
And this is after running bench you can see that i get a decrease of my cpu performance:
 https://ibb.co/99kKQF8 with balanced mode in power options.
 https://ibb.co/dcmPSZs with maximum performance.
I just saw this now that i seem to get better results with balanced mode in power options that in maximum performance. What is going on here?
Btw it can't be maximum performance fault because it is all in maximum. Includding cpu max and min performance are both at 100%


Here is also prints i took runing pc in maximum performance to show you my hw monitoring:

Also my ac-adapter gets very hot when im playing games, like very hot can't barely touch it....

mine is 4710mq, M17x R5, BIOS is latest A16.

but....looks like so many different.

Did u know ? bro

Hey I am using a P375SM clevo and I am trying this.  You say to select length 5000 but the image shows only a selected length 218 am I missing something?

Also when I try opening the file with mmtool the app will stop working and this is for either bioses.

 

EDIT: I got the stock bios and now mmtool works I think i got this now 4 entries show up in mmtool and 2 gone the once I wanted gone :P. Is this worth the risk? hihi

 

Hey just wondering how you went with the p375sm, I'll be trying it myself over the next couple of days.

      In this thread you can post your requests for Lenovo ThinkPad T440p / T440s / T540p.
      If someone wants upgrade Wi-Fi card and remove whitelist, or unlock hidden additional menus and settings in bios setup menu, then you can post your request in this thread.
      Important!
      For creating bios backup and to flash bios mod, you must use any SPI programmer  (like CH341A programmer) and a SOIC8/SOP8 test clip!
       
      Just dump your Bios using any SPI programmer  (like CH341A programmer) and a SOIC8/SOP8 test clip, then post it in this thread or upload it to any fileserver and send me the link.

      To install the unlocked bios, I prepared and booted a freedos usb. I start the installation by typing flash.bat but every time I get the following error: Error 28: Protected Range Registers are currently set by BIOS, preventing flash Access. Please contact the target System BIOS vendor for an option to disable Protected Range Registers.
      How can i solve this problem ?
