How to set up GTL Ref Values for 45nm & 65nm

[Bobly]

New question: Is something done different on the Asus Striker 2 Extreme?
People post GTL settings that look similar to this:
GTL ref 0: +50mv
GTL ref 1: +10mv
GTL ref 2: +50mv
GTL ref 3: +10mv

Except on my S2E, 0 and 3 have the same options (going from +14 to +224, and then negatives) while 1 and 2 have different options (going from +13 to 208, and then negatives). Does that mean I should be setting mine like so:
GTL ref 0: +50mv
GTL ref 1: +10mv
GTL ref 2: +10mv
GTL ref 3: +50mV
?


Edit: Arf this is crazy, I'm nearly stable, primed for 18h without errors and IBT works too (with GTLs on auto) but sometimes I randomly get system freezes, I've noticed they happen more often when I'm transferring a lot of info from one hard drive to another (either SATA to USB or SATA to eSATA) or when playing Assassin's Creed. It's weird but while all other games will work fine and sometimes system freeze every 24-48h, Assassin's Creed will system freeze within 15 minutes >.< Everest reported VTT of 1.28V so I've set it to that in the BIOS for now...



Edit Edit: Worklog

S2E w/	Q9550		REF0	REF1	REF2	REF3	POST	BOOT	IBT	STABLE
FSB	1866		42	0	0	42	X	FAIL		
Multi	8.5		14	39	39	14	X	X	FAIL	
Memory	1600		-7	26	26	-7	X	X	BSOD	
CPU-Z V	1.36V		-14	26	26	-14	X	X	X	FREEZE
PLL	Auto		28	65	65	28	X	FAIL		
VTT	1.28V		-21	26	26	-21	X	X	X	FREEZE
Memory	1.9V		-21	13	13	-21	X	X	X	
NB	1.5V									
SB	1.5V

X means pass, a fail will be indicated by the symptom of failure. First X means it posted, second means it booted into Vista, third means it passed 5 passes of IBT (not a real test, but it gives me a rough idea of if I'm on the right track or not, fourth one involves general use, usually crashes within 30 minutes on Assassin's Creed if incorrect).
