fenice19 Posted November 12, 2004 Share Posted November 12, 2004 i have purchased today corsair twinx 1024xl 3200 pro modules. i have seeen different treads concerning these modules and different failure on clock settings with different MoBo. This afternoon i will install these module on my motherboard ( Gigabyte K8vnxp equipped with athlon 64 3200 Bios F10). i would like to know the correct ( failsafe) clock settings for this motherboard.

Wired Posted November 12, 2004 Share Posted November 12, 2004 CAS Latency: 2T RAS to CAS Delay (tRCD): 2T Row Precharge (tRP): 2T Active to Precharge Delay (tRAS): 5T You may want to check change the RAS to CAS Delay to 3T if it's not stable.

Corsair Employees RAM GUY Posted November 12, 2004 Corsair Employees Share Posted November 12, 2004 With this MB the modules should be in slots 1-3 and I would suggest you set the Rass to Cass to "3" so I would set these timings and then set the Dim Voltage to +.2 Volts: CAS Latency CL=2.0 Row Cycle Time tRC Bios Default Row Refresh Cyc Time tRFC Bios Default Ras# to CAS# delay tRCD 3 Row to Row delay Bios Default Min Ras# Active Time tRAS 5 Row Precharge Time tRP 2 Write Recovery Time Bios Default Write to Read delay Bios Default Read to Write Delay Bios Default Refresh Period tREF Bios Default Enable 2T Timing Disabled Then test the system with http://www.memtest.org and make sure it's stable! If you have problems, I would set Enable 2T Timings to AUTO and test it again! Link to comment Share on other sites More sharing options...
fenice19 Posted November 12, 2004 Author Share Posted November 12, 2004 i have set cas latency=2 trcd =2 or 3 ( as suggested by ram Guy) tRas = 5 rtP=2 without overvoltage dim setting = auto with memtest at test 5 there are errors in 4 pass with an overvoltage of +0.1 no errors in all tests an overvoltage seems work fine i would like to know if this overvoltage could damage the dimms with pcwizard memories show: Information EEPROM () : Manufacturer : Unspecified Part Number : CMX512-3200XLPRO Serial Number : Type : DDR-SDRAM PC3200 (200 MHz) Size : 512 MB (2 rows, 4 banks) Module Buffered : No Module Registered : No Width : 64-bit Error Correction Capability : No Max.

Corsair Employees RAM GUY Posted November 12, 2004 Corsair Employees Share Posted November 12, 2004 All DDR modules would be by JEDEC Spec for DDR400 2.65 Volts + or - 1.0 Volts. And this module has a minumum suggested s voltage of 2.75 Volts. And all of our DDR modules are rated up to 2.9 Volts so there should be no problems, or we will be happy to replace them. Please see XMS Qualification and Testing. Link to comment Share on other sites More sharing options...
