Hello oskarha, thanks a lot and I've tried the modded BIOS you provided, unfortunately the same lag persists :(

If you followed the guide properly and have tried my bios then I dont know how to help you ¯\_(ツ)_/¯


[GUIDE] LGA 771 Mod for Dell Vostro 220 [GUIDE] LGA 775 BSEL Mod [BUILD] The Mighty Radeon-Powered Dell [VIDEO] Evolution of Intel CPUs

Can you game on an 8-year-old i7? Is the 4-year-old GTX 660 still relevant? Upgrading the HP Pro 3500

Hi oskarha,

I understand, no worries.

I played with risky thing this weekend. My X5450 is E0, to ensure absolute correctness of microcode I deleted everything except 067A_44, yes this is the only microcode in BIOS but still a NO go. I'm done now. Good luck to fellow hackers.

I had the same problem (G45M03 Slow)

ms-7594 has same problem, but it resolved

ms-7594 was solved by disabling C-STATE

 

vostro 220 bios 1.3.0 not has C-STATE
vostro 220 bios 1.2.0 has C-STATE
 

I tried mod bios based on 1.2.0.
And it was solved!

 

I added xeon microcode to 7C4D1P43.ROM and changed some defaults.
C1E Support Default Disable
Speedstep Default Disable
C-STATE Tech Default Disable

0A 067A 0B
11 067A 0B
44 067A 0B
01 0676 0F
04 0676 0F
10 0676 0F
80 0676 0F
10 0677 0A

You fixed it!

I modded my Vostro 220 a few years ago and had the same problem: very laggy windows 10 system due to high DPC and ISR CPU usage. Flashing your modded bios based on 1.2.0 immediately solved the problem.

I didn't need to disable Speedstep or C1E support. I only disabled C-STATE.

 

Thank you for sharing!

 

Additional info:

For the last 2 years I had Apple OS X installed on my Vostro. Strangely enough, the C-STATE incompatibility didn't effect OS X. It only caused a problem for Windows 10.

I'm glad it worked for you! Interesting remark about issues only appearing in Windows 10.I wonder if Linux would be fine too, this might be a Windows only issue.
