what suprise me is this pair of 5400UL seems don't like volt.>2.4v :eek:
2.6v will not boot in windows
2.5v boot ok , but failed in pi_1m testing
2.4v is the max.
2.3v~2.35v seems the best volt. @.@

Was it the same on other boards with those voltage? or did 2.6v work ?

haven't tested on other mobo.
only D975xbx in hand now.

but...I have another pair of PC8000UL in hand.
which like higher volt. 2.7v is also fine @.@
625mhz 5-3-3-8 done yesterday :p:

mine 5400ul also did fine on that !@$! aopen mobo with 2.8v only no gain because of that fsb wall.
400 3-2-2-1 on 2.5v but i hope it will be different on a other board.

VictorWang when you say "alu_solid_cap mod" what all have you done?

alu_solid_cap mod means I soldered alu_solid_cap instead of most of the cap on the mobo

Impressive clocks indeed :)

But how far does it clock w/ 1066 Strap?
Clock to clock performance gets quite a hit when going from 1066 to 1333 (and also allows a lot higher RAM clocks, but with less clock to clock performance).

pretty damn impressive on the 480 at 1:1 :)

I would love to see some Corsair XMS 6400C3 3-4-3-9 2GB kit would do with this mobo!!! Thats what I am looking at!

maybe ... 1333fsb losen the ram timings which we cannot set by ourselfs.
I'll try how far will it go @ 1067fsb :D

thx macci ;)
