riffraff

Recommended Posts

I contacted asus about my problems i am having if i try to run my memory in dual channel on my asus a7n8x-e deluxe mainboard if i run is single channel no problems but duel channel causes crashes in games and bluesreens and restarts they said that i need to contact you to set my memory timings manually and it would most likely fix my problems heres my system specs

 

asus a7n8x-e deluxe rev 1.01 bios 1008

athlonxp 3200+barton 400mhz fsb

2 512s of corsair cmx512-3200c2pt memory dimms

evga gforcefx 5900ultra 256 meg

300watt sparkle power supply

 

that should be enough info hope ram guy can help me set me timings?

Well first thing, you really should be using a 400 Watt PSU with that system configuration. In addition, please try these settings:

With the A7N8X-E please set the FSB jumper to pins 2-3 with the modules in slots 2-3 and then reset or clear the bios and load setup defaults and set the Dim Voltage to 2.7 Volts and set the timings manually. Then please test the system with http://www.memtest.org.

CPU Freq: 200 MHz

Memory Frequency: 100%

Dim Voltage to 2.7 Volts

Resulting Frequency: 200 MHz

SDRAM CAS Latency: 2.5T

SDRAM RAS to CAS Delay (tRCD): 3T

SDRAM Row Precharge (tRP): 3T

SDRAM Active to Precharge Delay (tRAS): 6T

 

I have had 4 of these exact MB's and this is what had to be done to solve problems with aggressive memory, no matters who's I tested. In addition, a few other's had some success disabling Spread Spectrum in the bios as well. I would take a look at http://www.asusforums.org as well in the AMD section.

Tried the settings you said and no erros with memtest but had no erros when running at on aggressive mode with the memtest either so i guess i will try a 400watt power supply and get back with you thx quick reply:)
