Download RWEverything.  Try portable version.
Go to Access->Command and run the commands:
wrmsr 0x199 0x0 0x00001128
rdmsr 0x198
rdmsr 0x194
Show a screenshot of results.

Done.
p.s. After having done it cpu speed suddenly jumped to 1.7Ghz

Now you can set CPU multiplier by RWEverything:
wrmsr 0x199 0x0 0x00001128
Do you still need a BIOS mod?

You mean after reboot cpu will revert speed back to 598 mhz
and I'll have to "overclock" it by entering such command every time?

Yes, I do, cause Windows boot time is very slow.

Can you restore BIOS in bad case?

nope.
but each person asked for a mod here has a chance to brick the board.
and i'm not sure each one so experienced in unsoldering and flashing by a programmer to "unbrick" it back

Don't pay attention - check CPU speed.

Nothing changed. Windows still shows cpu is working at 598Mhz.
Do I need to install old cpu and flash again?
