Another error:

 

Now when i am trying to make backup of my BIOS:

 

(on simple double click):

Quote

Error 284: Fail to load driver (PCI access for Windows).

Tool needs to run with an administrator priviledge account.

(Run as administrator)

Quote

Error 75: "fparts.txt" file not found

But as your may guess - it's in the same folder.

I am also added in *.bat file full address. Now it's look's like so:

Quote

C:\Folder\FPTw64\fptw64.exe -d BackupBiosY500.bin -bios
pause

 

SOLVED:

 

Right click on fptw64.exe and go to Properties => General Tab (press Unlock button)

Then go to Compatibility Tab and check box Run as Administrator

After that your are able to just double click on backup.bat

Lol, i am KEEP getting Errors!

 

New one is - i can't Drag-and-Drop modified BIOS in svl7 tool. =) It's showing me circle with "/" line.

I was smart and check box Run as Administrator in Compatibility Tab of BiosFixer_2.0.exe before running the tool.

 

So, now need go back and uncheck the box. :)

Hi guys

 

I am planning to install the modded bios soon. so, have a few questions.

1.I am running windows from an MSATA drive. Will this cause any problem when I install the modded bios?

2. is it possible to go back to stock Bios if there is some problem later?

3. which is the best wifi card in your opinion? 

cheers,

MJ

1. No

2. Yes

3. Intel AC 7260, but be sure to use WLAN Optimizer (http://www.martin-majowski.de/) with both 'disable background scan' and 'enable streaming mode' checked to prevent ping spikes caused by Intel's POS drivers.

its totally safe to use the mod, if my bios version is already  2.04. right?
@octiceps Thanks for the fast reply :)

 

Yeah it's fine. I flashed from stock 2.04 and have been running this for over 3 years now.

I am so frustrated with Lenovo ... is there a listing of all the companies that do this?  I'm starting to look for a new laptop and don't want to find myself limited by this stupid corporate moneymaking scheme.

My information could be outdated but as far as I know, MSI, Acer, and Asus don't have the whitelist bs.

Lenovo, HP, Dell, and Toshiba who are still doing it.

I'm looking at the changelog between v3.05 and V3.08 and the only thing I can find is:

 

Quote

Summary of changes
==================
General Information:

74CN47WW 
1. Implement code for uEFI security vulnerabilities. 

 

Is it worth to mod the v3.08 or just go with v3.05?

      Hi guys, I am the proud owner of a Clevo p775dm3-g notebook purchased from azom.systems (authorized Clevo reseller in India, Model rebranded as Azom Legion-17.3 inches). Here are my specs:

      Core i7 7700 (non-K version): undervolted by 110 mv and turbo boost disabled in BIOS- machine uses prema mod BIOS.
      GTX 1080: undervolted by 100 mv on all frequency steps using MSI afterburner voltage/frequency curve editor. clocks are untouched.
      16 GB DDR4: Cant remember clocks.
      1440p 120 Hz screen: No tinkering done to refresh rate.

      CPU has been delidded and repaste has been done on both CPU/GPU dies with gallium based TIM-Coolaboratory liquid ultra if I recall correctly.

      My issue is GPU hitting max temp limit of 90 degrees while playing DOOM and framerate drops from 110 avg to mid 60s-70s with horrible stuttering- this is thermal throttling for sure.

      System was running beautifully after repaste at 86 degrees max/ 77 degrees average at 100 percent fan speed. A month later I decided to see how much further I could push the system and ended up undervolting the CPU/GPU and RAM even further. The RAM undervolting part didnt work as well as I'd hoped, and I ended up resetting the BIOS to undo everything and reapply the previous setting (-110 for CPU with turbo boost disabled.) 

      I noticed that immediately after BIOS reset, both my CPU and GPU temps were 5-10 degrees higher even with the undervolt/underclock applied. Also, I think the fans were a bit louder before I reset the BIOS which leads me to believe that for some reason the fans are now capped at 80% max fan speed. There doesnt seem to be a fan speed selector in the BIOS or anywhere else so I cant say for sure whether this is a fan related issue or something else.Before the reset I could override the BIOS setting and set the fans to 100% by pressing fn+1, could I have done something to that setting after resetting the BIOS ? I dont think I have damaged the CPU or GPU as temps are holding fairly steady at 90-91 degrees and laptop doesn't shut down while gaming.

      If I have overlooked something or if anyone reading this has any solution help would be greatly appreciated.
      All settings/drivers/windows version/app version are exactly the same before and after BIOS reset.
