P5K-Dlx: CPU Voltage Reference & NB Voltage Reference effects on OC-ability

[Pretender]

XtremeTiramisu, try the following, instead of FSB Strap to Northbridge: 266 leave it in auto and use the same speed in memories. I have better performance in everest memory test(all of them) when using auto and 4:5 that when using 266 and 4:5.
Try and let us see your results.

Just confirming your final settings - so you ended up at x0.63 and 1.7?

Higher ref volts was better?

Glad to see you got it stable! Nice turn out....

I'm not having good luck getting Orthos Blend stable for the past couple of days, sometimes it will fail within the first hour and most of the time it'll even run up to 5~8 hours before it started failing.

I'm starting to suspect it's the Vcore that's still not enough all along, 1.465v Bios set.
Weird, I even had a screenshot of ~10 hours Orthos small fft stable at 1.6 CPU PLL and x0.61 CPU reference voltage in my post above.

Now I'm back running orthos small fft once again and if it's stable for 10+ hours, I guess it could be due to slightly too tight timings/sub-timings with the given voltage at 2.2/2.25v (5-5-4-7/8/9-3-25/30-3-3-5/6/8)

It has being taking me days to find the sweetspot at DDR2 1175 5-5-4-x-3-x-3-3-x and 2.2/2.25v...

Thanks, NB FSB Strap has being changed from 266 to Auto now and using the same 5:4 divider @ 1175 DDR2.

This is the exact same question I had for EVA2000 over at I4Memory. He believe that higher number = higher settings.

Therefore, x0.63 CPU Ref Vol & 1.7v CPU PLL > x0.61 CPU Ref Vol & 1.6 CPU PLL. However, this is what he believes from his experience. Only we can conclude whether they make a difference in the OC-ability in our own configuration
