Hi, I have such(z490-f wifi) motherboard, after upgrade from haswell 4770k to comet lake 10600k on my old win 8.1 I have lags and freezes which I notice in the browser and other utilities, all Ui elements renders slowly. After googling I’m found that problem in HPET option. I have try to disable with bcdedit and via “device manager”, after reload everything works better and faster . But anyway latency checker show yellow graphics(above 1ms)
Some questions to ask you. 1. Did you directly edit the cap bios? 2. How do you re-flash you modified bios? Is by bios flashback button? 3. Could you capture some screenshots under Advanced > PCH Configuration ?
Hi, @genius239 , thanks for reply 1. yes, I’m unpack cap bios file from zip and then open it via UEFITool 51.0(export AMITSESetupData) and UEFITool 25.0. when I made editing in hex editor, I make replace body by (edited AMITSESetupData) 2. then I place saved bios file into usb flash and re-flash by bios flashback button, I’m sure that this is was flashed because I have older version of bios, after flashing my version is changed to 1003. After this I made 2 another attempts(I have play with different bytes). Every time I was need to make downgrade to 0901 version, because flashback want work with similar(version wich now actual 1003) version of bios 3
@misanthrope1408 You’re welcome! This modify result is i expected. I remember i also unlock some menu items under Advanced tab , their next level still hidden many options.If you wanna get more ,i still need more screehshots to confirm something. Like i let you to capture “PCH Configuration”.
Yes, this modified cap bios is generic for all users who own a the same motherboard. You only need to capture screenshots under Advanced tab what you wanna unlocked sub-item .
