OptiX Posted September 29, 2006 Posted September 29, 2006 Hi there, FOA, I'd like to ask if this is the right place to ask for RMA.... I have the pair of stick for some months now, and they ever ran smooth... fast, cool... while some memory sticks run hot as hell, those would run real cool... Here goes the rest of the system specs: DFI LANPartyUT nF4 SLI-D (tried from BIOS 329 to 704) AMD Opteron 148 (Tried Athlon 64 3200+ too) 2x512MB Corsair XMS 3200XLPT v1.2 (not healthy ones) XFX 6600GT Vid Card 80GB Seagate P-ATA HDD LG 4163B DVD Burner ---------------- This last week it decided not to work correctly... random BSOD's... restart in the middle of gaming... So I decided runing some Prime95... where sometimes it passed 5 hours, others it would hang up at 15 minutes... So there was a friend who had a pretty similar system, and we switched our RAM, and for those 3 days I've been using his RAM (XMS 4400C25PT), my random crashes,BSODS and restarts are gone... So now I've got back my RAM, and tried A LOT of settings that I found over the forums, in order to get it stable... The settings were: Genie BIOS Settings: FSB Bus Frequency - 200 LDT/FSB Frequency Ration - Auto CPU/FSB Frequency Ratio - Auto PCI eXpress Frequency - 100Mhz CPU VID StartUp Value - Auto CPU VID Control - Auto CPU VID Special Control - Auto LDT Voltage Control - 1.20v Chip Set Voltage Control - 1.50v DRAM Voltage Control - 2.60v (Tried from 2.50V to 2.9v, wich Corsair says is the safe limit... still no go) DRAM Configuration Settings: DRAM Frequency Set - 200 (DRAM/FSB:1/01) Command Per Clock (CPC) - Enable CAS Latency Control (Tcl) - 2.0 {Tried also 2.5 and 3.0 but made things worse) RAS# to CAS# delay (Trcd) - 03 Bus Clocks (Tried 2 and 3) Min RAS# active time (Tras) - 05 Bus Clocks (Tried from 5 to 8) Row precharge time (Trp) - 02 Bus Clocks (Tried 2 and 3) Row Cycle time (Trc) - 11 Bus Clocks (tried from 7 to 17) Row refresh cyc time (Trfc) - 14 Bus Clocks (tried from 12 to 18) Row to Row delay (Trrd) - Auto Write recovery time (Twr) - Auto Write to Read delay (Twtr) - Auto Read to Write delay (Trwt) - Auto Refresh Period (Tref) - 1560 (Tried ALL OF THEM... 1560 and 3072 seem to be a bit more stable, but still unstable) Write CAS Latency (Twcl) - 1 Bus Clock DRAM Bank Interleave - Enabled DQS Skew Control - Auto DQS Skew Value - 0 DRAM Drive Strength - Auto (Tried from 4 to 8) DRAM Data Drive Strength - Level 2 (Tried from 1 to 4) Max Async Latency - Auto (Tried from 6.0 to 8.0) DRAM Response Time - Normal Read Preamble Time - Auto (Tried 5.0 and 6.0) IdleCycle Limit - 256 Cycles (Tried from 0 to 256) Dynamic Counter - Disable R/W Queue Bypass - 16 x (Tried 16x and 8x) Bypass Max - 07 x (Tried 4x and 7x) 32 Byte Granularity - Disable(8 Bursts) I don't have any ideas of what to do anymore... so I think the modules are bad since, since my friends' XMS 4400C25PT worked just fine, with all settings set to auto... Should I RMA them?
Corsair Employee RAM GUY Posted September 29, 2006 Corsair Employee Posted September 29, 2006 Please make sure you have the latest BIOS installed for your MB (download the Beta version) and load optimized defaults settings, and try the following BIOS settings; TwinX512 or Twinx1024-3200Xl Genie BIOS/DRAM Configuration DRAM Frequency Set: 2:1 or 400MHz or 200 (if option are 133/166/200) Command per Clock: Enabled SDRAM CAS Latency: 2T SDRAM RAS to CAS Delay (tRCD): 2T SDRAM Row Precharge (tRP): 2T SDRAM Active to Precharge Delay (tRAS): 5T And leave the rest at AUTO setting Genie BIOS FSB BUS Frequency: 200 LDT/FSB Frequency ratio: 5X LDT Bus Transfer Width: 16 16 CPU/FSB Frequency ratio: Auto PCI Ex: 100 K8 cool N’ quiet: Disable CPU VID Start Up Value: 1.55 (Depends on CPU but set it to +.5 Volts) CPU VID Control: 1.55 (Depends on CPU but set it to +.5 Volts) CPU VID Special Control: Auto Chipset Voltage Control: 1.6 DRAM Voltage Control: 2.8 All other settings are motherboards defaults Then please test them one at a time with http://www.memtest.org and let’s make sure it's not some other issue! I would run the test for at least 2-3 passes to be sure!
