kganann Posted November 16, 2004 Share Posted November 16, 2004 Hi there, I picked up a set of twin 512MB sticks with silver heat spreaders from http://www.newegg.com, either PC-2700 or PC-3200, which escpaes me right now, as I was building a new pc last year. Recently, I started getting a lot of errors, which quickly graduated to full-blown system crashes. I would get errors that windows tried to write to corrupt memory sector and crashed. At first I thought it was HD related and reinstalled, then I thought it was the MB (because the BIOS was corrupt, and kept corrupting) and swapped that out to a newer, better one. When I kept getting them I pulled both of my memory sticks, and tried them individually. With one, I kept getting crashes, the other is fine and my system has been running happily stable since. I was wondering if there was any further testing I needed to do to replace that stick, and if so, what, or if I should apply for and get an RMA for the stick. Sorry for the lack of complete specifics, I'm at work and the stick is at home. I'll update the info when I get home if needed. Thanks!

kganann Posted November 16, 2004 Author Share Posted November 16, 2004 Ah - here's the exact memory specs. CMX512-3200C2Pt, XMS3200, 400Mhz, etc. I did run Memtest98 and the one memory test Microsoft provides from their automated help - both could see memory errors, but at the time neither could determine if they were caused by the motherboard or the sticks.

Corsair Employees RAM GUY Posted November 17, 2004 Corsair Employees Share Posted November 17, 2004 Can you tell me the make and model of MB you have along with the CPU speed and it’s FSB as well? In addition, please tell me the bios settings you have set for both CPU and memory and any performance settings that you may have set? Link to comment Share on other sites More sharing options...
kganann Posted November 17, 2004 Author Share Posted November 17, 2004 I originally had an Asus p4p800-SE, which has been replaced with a Gigabyte GA-8I875 board with the dual bios. I'll reboot as soon as this update finishes and get you bios settings. I'm afraid I no longer have them for the Asus, and I'd rather not reinstall it just to get those settings, but otherwise we can play with it a bit.

kganann Posted November 17, 2004 Author Share Posted November 17, 2004 Okay, CPU Host Clock Control is Disabled, Memory frequecy is set to Auto (showing as 400 Mhz, with AGP/PCI/SRC memory freqs at 66/33/100.). Dimm overvoltage is set to normal, AGP overvoltage normal, cpu voltage nomal (1.5250V). The processor is a P4 2.8 Ghz with the 400Mhz FSB. Anything else you need? Thanks for your help!

Corsair Employees RAM GUY Posted November 17, 2004 Corsair Employees Share Posted November 17, 2004 Do you have 400MHz CPU FSB speed or 800MHz, please confirm this information, since this will affect and make a big difference on your system performance and setting. Please check in your BIOS if you have 200MHz set at or 100MHz, if you have 200MHz CPU clock frequency in the BIOS as your current setting then you have 800MHz FSB; if this is the case then please make sure that you have the latest BIOS installed on your MB, load optimal/setup defaults and set the following BIOS settings; CMX512-3200C2 Advanced Chipset Features (Ctrl + F1) DRAM Clock: 400 MHz Configure Dram timing by SPD: Disabled/User define SDRAM CAS Latency: 2T SDRAM RAS to CAS Delay (tRCD): 3T SDRAM Row Precharge (tRP): 3T SDRAM Active to Precharge Delay (tRAS): 6T SDRAM Burst Length: 8 SDRAM Bank Interleave: 8/Auto/Enabled (800MHz) SDRAM Command Rate: 1T Frequency Voltage Control CPU Freq: 200 CPU/DRAM ratio: 1:1 Memory or Dim Reference voltage: 2.7/2.75 Volts (+.2) AGP Voltage: Default *unless you have ATI 9200 or 9600 then 1.6 Volts suggested!* All other settings should be set to default settings! 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!

kganann Posted November 19, 2004 Author Share Posted November 19, 2004 Sorry, you're right, 800Mhz FSB. :o: It appears I'm losing my mind, sorry. I set the BIOs the way you recommended, but I didn't see Burst Length, Interleave or Command Rate under Advanced Chipset features. Still I set it and then ran mem test three times - once with the suspected good memory module, once with the bad, once with both. The good was clean through 10 passes. With both, I started getting errors and fails around pass 5. with just the bad I got them on pass 2. I think it's the DIMM, or is there something else we should try?
