lol what's with this impossible voltage?

yeah, I know those P45 boards don't like 4GB modules. I would very much like to see what happens on some old 1GB performance stick that can handle higher voltage, but I don't have any. At top of that the limits on BIOS timings settings doesn't give much space - Gigabyte EP45T has much higher... and even than it still has problems related to RAM.

Use: 1:1, 1 or 2 cores, 1.6vcore, SetFSB code: ICS9LPRS918BKL

1:1 is more unstable. After a lot of tests I concluded that this motherboard with high FSB prefers second to last option of RAM frequency (last and highest option is 1:1) at 400 strap. Next in hierarchy are some options from strap 333 and after that is 1:1 on strap 400.

But I will try and see what happens if I use SetFSB with 1:1.

 

BTW I have no idea why cpu-z and MemSet and Aida64 reported 1650MHz, BIOS setting was around 1520 or something like that.

 

I have c2d E4500 as my backup LGA775 because on one occasion motherboard recovered with previous BIOS version (without microcodes) and than it automatically reflashed even older one and so on with every reboot until c2d saved the day. Next week I will have a celeron 440 and I'm going to kill it

Forgot to add that I had two of those X5460 that were going even near 5GHz but due to insufficient cooling I wasn't able to access OS and provide cpu-z validation. I have made a picture of in-BIOS cpu configuration page.
