lordphoenix Posted March 22, 2005 Share Posted March 22, 2005 Alright. I have a Corsair XMS 512MB PC3200 v2.1 stick. I went to Monarch and found the timings were 3-3-3-8. The FSB on the MOBO is set to 333/400. The ram slot is the one all the way to the left (BLACK ONE). When I first booted up, the timings were 2-3-3-7 but I changed it to SPD, User defined, and then 3-3-3-8 (from the bottom to the top). Reboot, nothing. So I have to open the case and take out the CMOS BATTERY and change the jumper... BTW I'm on an AMD Athlon XP 2500+ (166x11) = 1.8 ghz I set it to 2.5-3-3-7 and it's somewhat stable but there are still some crashes (Video card is ZALMANIZED 9700 PRO, CPU is PRIME STABLE AXP 2500+). But I just want to know WHAT the REAL timings are supposed to be and WHY they don't work on the A7N8X DELUXE. Sometimes I crash in games... Maybe it's not the ram... I want to do a memtest on it but I just want to know one thing.. WHAT TIMINGS should I use for a memtest? the default are 3-3-3-8 but the only stable i could get is 2.5-3-3-7...??? <-- Confused? I have reset the cmos about 15 times. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted March 22, 2005 Corsair Employees Share Posted March 22, 2005 With a 333 FSB CPU you will need to set the memory frequency at DDR333 as well, please try these settings and test the modules one at a time with http://www.memtest.org to be sure. CPU Freq: 166 MHz Ssystem Performance: User Define Memory Frequency: 100% Dim Voltage to 2.7 Volts Resulting Frequency: 166MHz SDRAM CAS Latency: 3T SDRAM RAS to CAS Delay (tRCD): 3T SDRAM Row Precharge (tRP): 3T SDRAM Active to Precharge Delay (tRAS): 8T As long as you have CMX___-3200 modules, if not please let me know the part# Link to comment Share on other sites More sharing options...
Wired Posted March 22, 2005 Share Posted March 22, 2005 CAS Latency: 3 RAS to CAS Delay (tRCD): 3 Row Precharge (tRP): 3 Active to Precharge Delay (tRAS): 8 memory voltage: 2.7x or 2.8 volts set them to 166 Mhz to be in sync with your FSB.

lordphoenix Posted March 22, 2005 Author Share Posted March 22, 2005 Ok. I did all of that (3-3-3-8, 166 mhz, 166x11, 2.7 volts, 100%) and I get "SYSTEM FAILED MEMORY TEST" btw: REV 2.0 BIOS 1008 A7N8X DELUXE. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted March 23, 2005 Corsair Employees Share Posted March 23, 2005 Please tell me what you have the memory or DDR frequency ratio set to. Link to comment Share on other sites More sharing options...
lordphoenix Posted March 23, 2005 Author Share Posted March 23, 2005 RESULTING FREQUENCY : 166 MHz... Ratio??? No idea? Link to comment Share on other sites More sharing options...
