spacecookie Posted November 20, 2004 Share Posted November 20, 2004 ASUS K8V Deluxe AMD 64 1GB Corsair CMX512-3200C2PT (2 STICKS) all settings by spd 2 SATA Raids ATI Radeon 9800 Pro Started getting intermittant restarts about a month ago. First thought it was a bad sector on the hard drives but a program kept popping up that it would not continue due to possible bad memory. So I went looking for a memory tester, first one I tried was the windows memory tester that boots from a floppy. It would lock up. Found Memtest-86 v3.2 to try and on test #5 found 22 errors. Removed 1 stick and ran tests again with same results. Swapped out sticks for the other. All memory tests come out as passed. Took it 1 step further and changed the stick slots so that stick A was where stick B was and vise versa with both sticks in, 199 errors on test #5. Took it a step further took out the now known problem stick and set the CL to 2 instead of 2.5 with the known good stick ran all tests with a PASS no errors. Swapped sticks out again this time with the CL set to 3 still fails but with only 104 errors. Ran Windows without the suspect bad stick and it runs much faster. I believe the stick XMS3202v1.2 0328935 is a dodgy stick of ram. Link to comment Share on other sites More sharing options...
spacecookie Posted November 21, 2004 Author Share Posted November 21, 2004 To add BIOS is 1008 most recent non BETA, Memory timings are stock 2.5-3-3-6. If I put the DDR voltage anything other than auto IE 2.6 2.7 or 2.8 the higher it was the more errors the bad stick came up with. All settings are default FSB 200MHz so the stick is running in stock mode IE set to your specifications that you reiterate throughout the forums.

Corsair Employees RAM GUY Posted November 22, 2004 Corsair Employees Share Posted November 22, 2004 If you do not have a TwinX set then please set the following BIOS settings below, but if you do have a TwinX set then please set it at 2.5/3/3/6. Please put the memory module on slot 1 & 3; make sure that you have the latest BIOS for your MB, and set the following settings on your BIOS; Advanced Chipset: Memclock Mode: Limit Memclock Value: 2:1 (DDR400) Bank Interleaving: 4/Enabled Burst Length: 4 SDRAM CAS Latency: 2.5T SDRAM RAS to CAS Delay (tRCD): 3T SDRAM Active to Precharge Delay (tRAS): 7T SDRAM Row Precharge (tRP): 3T Hypertransport: 4X Jumper Free/Frequency Voltage Control: Spread Spectrum: Enabled CPU FSB Clock: 200 DDR Voltage: 2.8/2.85 Volts AGP Voltage: Default *unless you have ATI (9200 or 9600) or NVIDIA (5200 or 5700) 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!

spacecookie Posted November 25, 2004 Author Share Posted November 25, 2004 Thank you for your reply Here is an update Tried the settings you mentioned on the known bad stick to an extra 3-4-4-7 and it still fails test #5 of memtest. Also I started haveing problems with the remaining stick which memtest gave a clean bill of health. Quickpar on the secondary raid would allways fail and the computer will randomly restart copying files from raid to raid, Quickpar works fine on the other raid if I can get the files copied. Ordered some new ram all copying from raid to raid works without problems with the new stuff. Quickpar works fine on both drives as well. Memtest gives the new stuff a good bill of health too. Here is my question can memtest FAIL to detect a bad stick of memory like that and pass it? I rann 22 passes I think I might let it run all night. And to add the stick that fails, fails by itself and in any of the 3 memory slots in stock by SPD mode or the slower 3-4-4-7. The other stick passes, I find this very strange. Another question, when I baught this memory it was the newest best stuff and I don't recall it mentioning TWINX. They did come in a duel pack IE both 512 sticks in 1 package but yet it doesn't specify TWINX on a sticker like I am hearing so am I safe to assume it is not TWINX? Both sticks are otherwise identicle CMX512-3200C2PT XMS3202v2.2 0328935 XMS3200 512MB 400MHz CL2 Link to comment Share on other sites More sharing options...
spacecookie Posted November 25, 2004 Author Share Posted November 25, 2004 Any other test you can recommend besides memtest for me to try would be wonderful. MS memory tester with the bad stick locks up, failes the other and fails the new ram, go figure... Link to comment Share on other sites More sharing options...
