BADMEM Posted April 6, 2005 Share Posted April 6, 2005 My Problem: Memory errors on the WMD test & Random Crashes. Q: Is one of my memory chips bad or mismatched? Q: Why isn't the SPD info on my chips (2.0-2-3-6) the same as the Corsair specs (2-3-2-6)? Q: Is there something wrong with my BIOS settings? My system: Corsair Platinum Twinx DDR 2 x CMX512-3200LLPT XMS3205v1.2 512MB 400MHz 2326, 040313-1 Intel Desktop Board D875PBZ, BIOS is up-to-date and set to defaults, System is not overclocked see http://www.intel.com/design/motherbd/bz/ Intel P4 3.20GHz / Gforce FX 8900 BIOS SETTINGS: BIOS VERSION BZ87510A.86A.0123.P33 Processor Speed 3.2 System Bus: 800 MHz System memory Speed: 400 Mhz L2 Cache RAM: 1MB Total Memory: 1024MB Memory Mode: Dual Channel BIOS MEM SETTINGS CPC Override: auto SDRAM Frequency: 400 Mhz SDRAM tCL: 2.0 SDRAM tRCD: 3 SDRAM tRP: 2 SDRAM tRASmin: 6 Memory Refresh Cycle Time: 12 Clocks Memory R/W delay: 2 Clocks Memory R/W timing: 6 clocks DDR Voltage: 2.625 Volts Total memory: 1024 MB Memory Mode: Dual Channel Memory Channel A Slot 0: Not Installed Slot 1: 512 MB (DDR400) SPD: 2.0-2-3-6 Memory Channel B Slot 0: Not Installed Slot 1: 512 MB (DDR400) SPD: 2.0-2-3-6 SPD defined as: [tCL]-[tRcd]-[tRP]-[tRASmin] With the above configuration, I ran Windows Memory Test and got quite a batch of errors. WMT could not identify the errors by memory module. The errors occured both with the Cache on and off. I switched the 2 chips to the 0 slots, but got same errors as above. Ran WMT with one stick (Call it MEM-A) in Channel A, Slot 0 and got NO ERRORS. Then tested other chip (CALL it MEM-B) in same place and got NO Errors. Then tested MEM-A in Channel B, Slot 1, and got No Errors. So, it seems the errors are related to the DDR mode -- which is the whole point of this memory. Also, when I set the BIOS setting to match the chips SPD, the system would not POST. So, what is going on here and what do I need to do to get my system to run with both memory sticks inserted in DDR mode? Thanks for your help.

Q: Is there something wrong with my BIOS settings?SDRAM Frequency: 400 Mhz SDRAM tCL: 2.0 SDRAM tRCD: 3 SDRAM tRP: 2 SDRAM tRAS: 6 DDR Voltage: 2.625 Volts Those are the correct timings that you have set. They are tested @ 2.75 volts, so you should up the voltage to 2.7x or 2.8 volts. They're warrantied up to, but not over, 2.9 volts, so no worries there.

Corsair Employees RAM GUY Posted April 6, 2005 Corsair Employees Share Posted April 6, 2005 Please try and set the Dim Voltage to 2.775 Volts and test the modules with http://www.memtest.org one at a time. Moving this thread to General Questions, as this is not a Customer Care Issue! Link to comment Share on other sites More sharing options...

Moving this thread to General Questions, as this is not a Customer Care Issue! OK, Done. Left BIOS settings the same as above, except I did change the DIM Voltage to 2.775 (which is the max for my board). Ran Memtest on each module seperately. One came back with a bunch of errors on the first pass. The other one tested for 3 passes with no errors. Can we at this point assume that the module that produced the errors is bad and can I get a replacement from Corsair? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted April 6, 2005 Corsair Employees Share Posted April 6, 2005 Yes lets get your modules replaced, and No I am sorry that is not a Customer Care issue. Please follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it! Link to comment Share on other sites More sharing options...
