Issue with 2BGHV DDR500 on DFI-nF4 SLi-DR Expert

[djdecker]

Using DFI NF4 SLI-DR EXPERT
AMD Dual Core 4200+
GSKILL 2BGHV DDR500.

Tryed settings from Forum, system reboots after bios loads.
Changed settings back to default, system only seems to work when using ram in single channel mode.
Changed a few settings, left all timings on auto, got windows to load but system hangs.

Tryed FSB at 250 with all other settings default, system restarts, at 200 seems ok.
Anyone able to suggest anything?

edit// system is stable with auto settings as long as the Mhz 200:1/1 is set to auto...

use 200 1:1 and pull the FSB to 250 and see it is stable or not :)
also remember set htt to 3x

I am using a 20 pin psu, was wondering if i need to mod this to suit 24 pin to perhaps get stability with 1t and 250Mhz DDR500 settings??
Using 550 wat true control 2 antec server psu.
Only 1 7800GTX card in system at present.
