Oh yeah Cryptik...Almost forgot...I just want to ask you...Is there any improvement with the modded BIOS from Ket?

Is there anyone of you could explain the function of vtt for dram and nb...???
Truely I'm little confused to set the gtlref menu in BIOS coz it's different with the other mainboard as usually I handle before...
Cryptik could you help me please how to "translate' and making the calculation for the gtlref for nb is the main important I think...???
thanks for your help and for the link of new BIOS from Ket...
And I had a little problem to make my rig going stable with FSB 500-550...
I could found stable setting at 533FSB/1066RAM...but not at the other FSB setting...
What is the best strap for this motherboard?

Vtt is not controllable through bios it is 0.5x Vdimm. DDR Ref Channel A/B and NB DDR ref voltages are controllable, but I'm not sure what purpose they have at the moment, I'm researching it. I have mine on auto at the moment.

I also have left GTL for NB on auto (0.64x Vtt) and I have found changing it up or down didn't help me overclock higher (my board wont go above 570 FSB) however it may allow slightly less vNB to be used for 'normal' clocks - I'm yet to establish this.

I can be stable at 534 FSB, above that starts getting shaky, not sure why at the moment. I think these boards need more vNB than other P45 boards to get 530+ FSB stable, but other factors may also be playing a role.

I like the 266 strap, it's efficient (as a P45 can be) but 333 is also good. Whatever works for your FSB and desired ram clock I guess.

Yes there was an improvement, I could clock ram higher, but at that stage I didn't know how to clock ram high on this board. I changed back to Asus 1307 and have been on that since as I can get the ram over 650 MHz using it (now I know how to), but soon I will be using Ket's again and will do some testing.
