    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 ;)) 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. 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: , 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 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: Click on Start Type CMD in the Search box Right-click on CMD and choose Run as Administrator In the Command Prompt window and change to the directory where the file is located. To do this, use the CD command. You can follow the example below. to change to the Windows\System32 directory you would enter the following command and Press Enter cd \windows\system32 Now use the DEL command to delete the offending file. Type DEL mcupdate_GenuineIntel (and backup) Done! Overclocking: 1) Check CPU MCID:Download 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, LOL 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, cpu@4.3Ghz, +200mV adaptive vcore: I'm also getting 852 with 4.5ghz with this adaptive voltage-like method: 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... 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 :P) Happy overclocking, and don't melt your laptop Thanks to Intel if they leaked this on purpose, kinda futureproofed my machine XD P150SM 1.03.05 modded bios (at your own risk): MOD EDIT: link removed, please use a clean BIOS base because of legal implications with Intel :

    Keep in mind WCCFTech is very anti-NVIDIA and they always tend to slant things as pro-AMD. Asynchronous compute is not a big deal and if the market leader (NVIDIA) is the weakest link, rest assured most devs won't make async heavy games that harm NVIDIA.

    Tech Inferno Fan>> June-1-2015: BPlus have released a soldered cable PE4C 3.0 with better Gen2 and even Gen3 compliance. It is recommended over any previous PE4C 2.x or 1.x that used the a socketted cable giving unreliable Gen2 compliance. See details. Welcome to this thread. In this thread, we'll discuss about Bplus's latest eGPU adapter, PE4C V2.x. If anyone has any question, please don't hesitate to ask. I'll be glad to help you. Here's what you need to know to get started: Product's picture : This product supports Gen2 PCi-e speed, which means that you get about twice as fast as the Gen1. What's good thing about this is that PE4C v2.x is powered by Dell 220W AC-MK394 Adapter that's enough to run cards like GTX 680 or 760 and also remove the reason of owning a bulky and messy power supply. PE4C V2.0 has two hdmi connector for x2 link connection.This product has a big base to make it look more high quality, and it help to stabilize the adapter. Also, there is a card lock that holds the GPU from accidental card removals. Here's the product's parts to make the story short: Price for each option is US$105 excluding shipping, US$134 including shipping. Please if you have PE4C V2.x, share us your experience. Details about PE4C V1.2 instead is here: cheaper, x2 capable, flexible FCC cable but only Gen1 capable Product History 2.1 Oct-14: increased price $90->$105. Introduced 4-pin CPU power connector and native 8-pin Dell DA-2 connector 2.0 Sep-14: initial release

    It would be really nice to try this on other Haswell CPUs, results would be interesting, guess 4900mq can go 4.8ghz stable due to having high quality ASIC compared to 4700mq, 200+mV to reach 4.6 should be less with better cpus

    It's almost a catch 22... most of the the industry kisses NVIDIA's heiny and empowers them to maintain status quo. I'd love to see AMD kick 'em in the privates hard enough to cause serious injury, but I think there is a snowball's chance in hell of that happening. NVIDIA truly has a monopoly and that allows them an extraordinary amount of liberty to thrive in spite of their overall mediocrity. The general assumption is NVIDIA is always better, and to an extent it becomes a self-fulfilling prophecy. It is not good for us that, year-over-year, they are competing mostly with their own last gen products. It's really unfortunate from every angle regardless of whether you are a red or green fanboy. I think it also has something to do with the stupid $hit we see from NVIDIA, like out of the blue a position stating they do not support overclocking on notebooks. They don't need to care because, generation upon generation, since 7970M, AMD brings nothing of value to the table for high performance notebook enthusiasts. Here's hoping something revolutionary comes to notebook performance enthusiasts from AMD in Polaris... not going to bet my paycheck on it though.

    Found another typo That should be 06C3, since that's the microcode we're removing :)

    In the block you have highlighted in your selection starts with a "01" not "00". Was this a typo, or do you start the selection at "00"? Either way, after deletion it leaves a "01" there, I just was hoping for some clarification

    @MoathSama Well, what did have your settings been? Please use the stability test in the Intel XTU after you lowered your volateg. Maybe yours can only take -40mV or sth else. @gharimanto The CPU starts to throttle at 99-100°C.

    Can you please make a VBIOS for the alienware 17 R3 GTX 980m 8 gb? It uses a BGA GTX 980m 8gb, not a MXM so the clevo vbios doesn't work. https://drive.google.com/file/d/0B7nOtMXiwOUYLV9WdmF6amcwLXc/view?usp=sharing Here is the stock vbios. Thank you.

    Agreed, unless you need a new laptop RIGHT NOW, I'd wait on the new GPU releases.

    I recommend a slightly pricier BPlus PE4C V2.1 over any EXP GDC product as it has no Gen2 expresscard signalling issues when tested on my Dell E6440. The EXP GDC V6 does glitch occasionally with a "NVidia driver has stopped responding" with the manufacturer unwilling to supply an updated Beast product for review. I'm therefore assuming the problem hasn't been corrected. Why US$83-shipped 0W PE4C V2.1 is better than a US$50-shipped 0W EXP GDC V6? | Why US$134-shipped 220W PE4C V2.1 is better than a US$99-shipped 220W EXP GDC V6? Picture comparison: Download >> PE4CvsEXP << + Tech Inferno Fan has found clean Gen2 signalling of the PE4C V2.1, whereas EXP GDC V6 has unreliable glitches + Has a PM4N socketted mPCIe option + BPlus have a history of delivering quality products to the DIY eGPU community. + Easier to purchase with quicker delivery + Has H1PA option -> can connect to a desktop PC to extend the slot + Has a x2 link option, though this is primary for users with 1st gen i-core or older systems. Intel locking down 2nd Gen i-core or newer systems to prevent that. + Has locking x16 slot + Support two delay switch (PCIe Reset Delay and CLKRUN) to avoid registration problems when booting + 0W BPlus offering includes the special PCIe power cable that the EXP GDC V6 0W package does not
