  1. Hi guys! I have a big problem-> I need to undervolt my GPU (MSI 7970M@DELL_BIOS). I am using this vBIOS: https://www.techpowerup.com/vgabios/132831/dell-hd7970m-2048-120629 Stock VDDC on this GPU is 1.050V and when I changing this one to 0.975 in VBE7 it is ok-> I can save it and flash it. Computer succesfully restarts but when I check modded settings the VDDC is still on 1.050V I checked if the VBE7 seriously saving the VDDC to vBIOS but it is ok. I have no idead what i need to UV this card (i know it's possible...) Everything is changing (GPU, MEM MHz) but VDDC can't change. Please help me ;-)
  2. Hello earth, WARNING: although this is a semi-guide, what you're about to read isn't for the faint hearted XD, I'm not responsible for any damage, fire, death to your pet etcetera if you attempt to do it... As you may already know, you cannot force custom timings on intel igps, unlike dGPU system only, since Intel IGP cannot do EDID overrides. More about EDID: https://en.wikipedia.org/wiki/Extended_Display_Identification_Data The solution was to dump the EDID which can be done using modeline in windows registry, linux modeline, or dumping directly from the EEPROM (electrically erasable read only memory found physically in most screen logic) which should be straightforward as we need to actually reflash it with our modification simply over i2c interface using arduino (simple 328 with serial-to-usb, can be from 8$ to 25$ max) you can also buy an EEPROM programmer which can be slightly expensive. The screen I have is a CMN1B, Chi . Should also work with AOU 95% gamut screen, any screen with i2c interface to eeprom, you can actually trace it along the 18th and 19th pin from the LVDS cable, however it should be pretty visible. So I ended up (easily), disassembling the screen as per this guide: [GUIDE] How to replace an LCD panel on a Clevo shell (pictures included) | NotebookReview I've then cut the film from both sides then taped for making it easier to work (i.e: instead of cutting EEPROM's pin location): There are 2 EEPROMS in my case, identified it simply by looking at the test point tagging, EE_SC SD etc, should be similar in any other displays: Tip size reference, basically any 15 to 30 watts soldering iron should work, unless the testpoints are tiny on other displays like AUO, though it is least likely you will ever have to desolder the EEPROM chip: Sold'er! Roger that(You can see the EE_* tags, SC for clock, and D for data etc): Connect to my Duino(wire it as you normal i2c): My EDID dumped in Linux before proceding to flash: EDID: 00ffffffffffff000daeb11500000000 01160104902213780231d59f56589527 15505400000001010101010101010101 010101010101963b803271383e405a3c 690058c21000001a9b2580ee70382340 3523350058c21000001a000000fe0056 434d3858024e31353648470a00000000 000041319e0000000002010a20200005 BACKLIGHT: 133 range: (0, 976) Backlight: 133 range: (0, 976) scaling mode: Full aspect supported: None, Full, Center, Full aspect Broadcast RGB: Automatic supported: Automatic, Full, Limited 16:235 audio: auto supported: force-dvi, off, auto, on 1920x1080 (0x4c) 152.5MHz +HSync -VSync *current +preferred h: width 1920 start 2010 end 2070 total 2226 skew 0 clock 68.5KHz v: height 1080 start 1086 end 1095 total 1142 clock 60.0Hz Pasted in Deltacast EDID editor then modified Pixel clock from 152 mhz (60hz calculated in DTD calculator) to 209 mhz, you have to calculate by entering these from the upper code repecitevly from top to bottom 920x1080 (0x4c) 152.5MHz +HSync -VSync *current +preferred h: width 1920 start 2010 end 2070 total 2226 skew 0 clock 68.5KHz v: height 1080 start 1086 end 1095 total 1142 Export the modifications in EDID editor as hex, make sure you add 60hz(original mod) in block 3 so you can switch between 40 60 120, then using find&replace method modify the format according to the next step Then modify the array in the code (acc to format, 0x and ,) upload to arduino: https://learn.adafruit.com/adafruit-tfp401-hdmi-slash-dvi-decoder-to-40-pin-ttl-display/editing-the-edid I'v managed to go up to 120hz stable, yours may be different although the same model number... xrandr output at 85hz: Had to reboot twice on Windows under UEFI boot manager in order to recognize the 120hz option, weird Again, this is not a thorough guide, just sharing my experience. It went pretty straightforward, and simple as a typical EDID modding over VGA cable or DVI.
  3. my m17x r4 does not allow to change tdp<!-- google_ad_section_end --> <!-- google_ad_section_start -->hello i am in the dark TT. i am trying to oc my 3820qm and i've done it. But i want to keep the turbo mode more than 56sec(long power timewindow). i have done everything to solve this on my m17x r4. i've changed bios from a05 stock and a05 unlocked to a11 unlocked and a13 stock, and even installed every version of xtu and TS. The problem is it screen looks like tdp is changed in the bios, xtu and TS. However cpu never uses more than 55w and then after like 56sec it throttles down to 45w(that is 3.4ghz) i have disabled msr lock, changed short/long limit to 75(and even higher) and changed timewindow to 56sec(and higher too). But nothing seems to help me. People say they can run r4 at max turbo clock all day and i also have seen one of those screenshot. For me, it works as if msr lock isn't unlocked. Is there any way I can solve this? or is it just non-XM CPU's capability or even m17x's capability?
  4. Hello, I have this gaming notebook with a 970m 3gb, I need a custom vbios so I can overclock it, I've been surfing the web but I can't find anything good... Any help? Thanks in advance.
  5. I gather from reading around that without a new vBIOS you can overclock the 680M from the stock 719MHz up to 854MHz (+135), is that true..? So with a new vBIOS, how far have people ramped-up the clock..? Does it get anywhere near the 970, in terms of game performance..?
  6. So I screwed up today, and tried overclocking my HD 7850 with sapphire trixx, which immediately caused the drivers to hang, and I got a black screen where my cursor could still move. Nothing would respond, so I had to force shut down, and now my laptop will get stuck on a black screen when trying to boot with the PSU powered on, meaning it won't even get to the BIOS. I've already tried a system restore and uninstalling Trixx, which did nothing. The fans still spin, so I don't think it's fried. I'm running the gpu through the PE4C 3.0 into the laptop's mini PCI port. I have a feeling the bad settings are stuck on the card, and since I can no longer access the card through Windows, I don't have any way to reset it. I run an Optimus laptop setup, so the only way the card can be detected is at powering on. I'm about to try and uninstall the AMD drivers, but I'm doubtful it will do anything. Does anyone know what I could do? Or am I SOL?
  7. Hi there! As Afterburner 4.3 beta 14 gives access to the voltage curves, I plaed around some and found out that one can undervolt the GPU with some success. After locking my GPU clock on 1709 mhz @ 800mV and the RAM clock on 4498 mhz I was able to run the Witcher 3 with the same framerate (73.5 FPS 1080p ultra without Hairworks) as under standard voltage - anyhow my notebook was consuming about 15-17 watt less (152 instead of 168). With G-Sync enabled (one might as well say with FPS locked to 60) the result is even mor drastic, as the GPU won`t clock up as the load decreases in light weigth scenes. I could reduce the power consumption about 20-30 watt (128 instead of 156), depending on the GPU load. Perhaps some of you guys care to post their results, and perhaps are able to answer one question: I thought with GPU clock locked to 1709 an RAM to 4498 I thought I`d surpass the standard settings in regard to the FPS - still this is not the case. I know this has to do with th undervolting, but still... Best regards phila

  9. ok, so, i have a serious problem atm. im trying to mod my bios so that i can go past the normal overclocking limit. however, everytime i try to do it, it always says "file size does not match existing bios size!", and it's really annoying, since i had to find everything myself, as no one else online tried this on my specific model, besides me. (which surprises me, really) this is the guide im following: So this is my detailed description how I managed to mod and overclock my GTX 960M in my Lenovo Y50-70. Please note: it is very dangerous to play with the BIOS, so you need to be very careful! I take NO RESPONSIBILITY for any damage or misuse of the information below! Use it AT YOUR OWN RISK! ------- Necessary tools: A. Fptw64 from Intel (9.5 or above) http://forum.hwbot.org/showthread.php?t=75024 B. PhoenixTool (2.50 or above) https://www.bios-mods.com/tools/index.php?dir=Andy+P+(MDL)+Phoenix-Insyde-EFI+SLIC+Tool%2F C. Maxwell II BIOS Tweaker (1.36) https://www.techpowerup.com/downloads/2562/maxwell-ii-bios-tweaker-v1-36/ ------------------------- How to flash Modded BIOS: 0. Flash the latest (3.03 now) official BIOS 1. From Windows, start 'cmd' as Administrator and read your your BIOS via Fptw64: Fptw64 -d BIOS.ROM -bios 2. Reboot, enter your BIOS and check "Enable downgrading BIOS" feature (we need to downgrade first in order to flash the modded BIOS) 3. From Windows, downgrade to 1.13 (this is necessary because the newer BIOSes have protection against mod-ding) 4. After reboot & reflash, start Windows, then enter standby, wait a bit, then wake up the machine 5. Create your modded BIOS, see separate list below 6. Start 'cmd' as Administrator and write your _modded_ BIOS via Fptw64: Fptw64 -f BIOS_MODDED.ROM -bios ------------------------- How to create modded BIOS (point 5 above): 5.1 Start PhoenixTool.exe from Phoenix Tool 2.50 and open your previously saved original BIOS.ROM from point #1 above .2 The tool analyses it and shows some messages, click OK .3 Now you can find your vBIOS in the "DUMP" subfolder in the folder containing your BIOS.ROM, with the file name: BE13645B-2C2C-44D2-A64F-0EA052C34597_1796.ROM .4 Create your modded vBIOS, see separate list below -> let's call it 960M_OC.MOD .5 Click on "Structure" .6 Open "EFI BIOS" tag .7 Open second "File Volume {7A9354D9-...}" tag .8 DXE Core -> Compressed Section -> Raw section -> File Volume {7A9354D9-...} .9 In the very long list, find the following tag (usually displayed at around 80% of the list): Freeform {BE13645B-2C2C-44D2-A64F-0EA052C34597} This is the item containing the latest vBIOS .10 Open the tag, then "GUID defined section", then click on Raw section. "Internal number" (in the top right corner) should be 1796 for BIOS 3.03. .11 Click on "Replace" and select your modded vBIOS (called 960M_OC.MOD above) .12 Click exit "Exit" and say Yes to "Save changes?" .13 Close the Phoenix Tool; now you should have your BIOS.ROM updated (the original will be saved as BIOS.ROM.OLD for safety) ------------------------- How to create modded vBIOS (point 5.4 above): Use Maxwell II BIOS Tweaker to change BE13645B-2C2C-44D2-A64F-0EA052C34597_1796.ROM; 5.4.1 Open the ROM .2 Change "Boost Clock" on "Common" tab to the new boost-ed maximum value .3 On "Boost table" tab, use the slider in the right bottom corner to increase your max boost-ed value to the same number .4 On "Boost states" tab, at P00 profile, change the MAX values in the GPC, L2C and XBAR fields to the same max boost-ed value .5 Save your modified BIOS and rename it to 960M_OC.MOD (My boost-ed max value was 1359 MHz. I could then use MSI Afterburner's software tuning -> my 960M could reach 1454 MHz without voltage increase.) i know that it's for a different laptop, but its basically the same ill provide more info when im home
  10. Some people are able to successfully overclock the GTX 660m to 1200mhz GPU Clock and 2500mhz Mem Clock but I keep experiencing driver crashes. Screenshot
  11. Hi guys, I'm interested in increasing the voltage of my graphic card. I followed the tutorial to overclock my card with a custom vbios but i still cant modify the voltage in the nvidia inspector tool. How could i modify my vbios to increase the voltage ? Here is the tutorial im talking about : http://forum.techinferno.com/asus-gaming-notebook-forum/2538-%5Bg75vw%5D-modified-bios-vbios-higher-overclocking.html Thanks a lot
  12. Hi, @Prema First of all I'd like to thank you for all your effort in your moddings. I've been following you for a long time and your work is so appreciated. So it is that I made a donation to support your activity. It is not much, sadly, what I could offer but I hope it helps. On the other hand, I would like to know a few things about my new laptop (Lenovo Y50-70 & GTX 960M) and I hope you will be able to help me to understand. I've been reading a lot about the lock Nvidia put to its drivers recently. Fortunately, it seems now the problem is gone and we can oc'ing our video cards just by flashing a modded vBios. Well, what should I do? I mean, I read there's sometimes problems with the bioses and I remember I've seen something, in particular related to my laptop and Lenovo Bioses. Am I correct? Should I take anything else into consideration before applying your mod? Finally, I'd like to know if an OC+Underclock is feasible with this card? Thanks in advance, Prema.

    i7-4700MQ Overclock Help

    I have prema bios v2 on sager p150sm. Anyone with an i7 4700mq have any stable numbers they use for overclocking the CPU. It seems the general consensus around here is to use Intel XTU to overclock the CPU and to not do it in the bios.

  15. Hey Guys, Having trouble with my 7970m, it hard freezes pc at any overvoltage. Is this a PSU issue? Its in my Alienware m17r4. I was trying to run 1.075v at 980/1380. It froze, so I took it back to the stable OC of 925/1300. Still froze. Took it back to stock clocks and guess what. It froze! On stock clocks! This only happens when I disable the integrated graphics. (I assume enduro prevents the card from hitting max power use/performance/whatever) On stable clocks, dedicated card only, stock volts i get 50 fps in I:SS. With enduro on, at 1000/1400/1.075v i get about the same fps. With enduro on at stable clocks and stock volts i only get about 34fps... so obviously enduro is throttling me somewhere. I just don't get why it crashes on voltage, shouldn't this not be possible at stock clocks?? Do I have a dodgy alienware? Thanks guys, Scott.
  16. During GPGPU benchmark for my 'overclocked' i7-4720HQ, at the AES-256 part I will always get an auto shutdown which does not happen at stock. Anyone knows why it happens / what's wrong with my XTU profile? Benchmark mentioned above: XTU profile: A couple questions: Should I increase cache ratio and current limit? What does changing turbo boost power time window do? All help is appreciated!

    Wanting to learn to mod BIOS

    Hello, I own a Lenovo X130e with an Intel Celeron 857 CPU and Intel HD Graphics. Is it possible to overclock these by modding my BIOS? If so, would anyone be willing to assist me to mod by BIOS? Thanks.
  18. Morning all, First post . I have a Clevo P150SMA, it's about 6 months old now. Luckily I have some really nice temps at the moment:- CPU/GPU never seem to go above 60c. So I though let's overclock! I have flashed prema mod BIOS and now have no idea what to do next to overclock. I'm used to overclocking on AMD desktop machines but not Intel/nVidia laptops . I normally dual boot linux/windows, linux is my main OS and windows I use for gaming so I would prefer BIOS overclock, although for GPU this is not that important. MSI Afterburner does not allow me to overclock. So I far I believe the best thing to do is flash a vBIOS for the GPU to allow overclocking in afterburner and overclock the CPU in BIOS. My question is how do I overclock the CPU in BIOS and any other advice. A guide to prema mod BIOS overclocking would be great but I can't find anything.

  20. I am using msi afterburner to overclock the 675mx on my ibuypower cz-17 (i am pretty sure it uses the same hardware as msi) When i do so GPU-z Gives me weird results. The results that i am getting seem like the core clock is stuck at 653mghz when it should be 800mghz. The is room in the gpu-z graph to go up when overclocking is enabled. i tried all the power save options to max performance. I also tried to lock voltage. No good. I cant flash a vbios because i cant find one (other then the one on this site that i cannot download ) if anyone has a suggestion or a link to a download for the 4gb 675mx bios let me know.
  21. I know it's pretty old, but I hope my old laptop can get some more love. The bios is attached here. Hopefully someone can look at it and see what is possible. Thanks! G53JWAS211.zip

    OverClock for GT650M

    Can Some one Help Me With The Best Stable Overclock On your M14xR2 With 650M?? I have Flashed svl7 's Unclocked BIOS A03
  23. Hi guys, I was wondering if you could help me overvolt/undervolt the np6165/w150erq's embedded vbios. The stock sager bios dump is here, courtesy of prema from notebookreview forums: W150ER_06_stock.rar The thing i've noticed is that the 650m's max normal voltage under stock conditions is 1.037v but for some reason it goes to 1.012v when under use. It goes back to 1.037 when the gpu is not under use. I'd like to fix that for a start pls. I've also modded my laptop by adding heat pipes and stuff. More to come soon.
