WatZun Posted December 22, 2006 Share Posted December 22, 2006 I was getting this error: The instruction at "0x241f94f7" referenced memory at "0x0d8bf41c". The memory could not be "read". While playing HL2. Lanparty UT nF4 SLI-D CMX512-3200C2 v1.1 dual channel, not matched set, but matching versions. AMD64 3500+ 2 BFG 7600GT in SLI. Error appears to be unique to Half-Life 2. One of the modules originally did not post, then did post for reasons I do not understand. (Tested it in 3 different Mobos that Would post using a different stick, then tried it again later and it worked and has ever since???) Everything was fine till dual channel. I was able to obtain another matched version. But started getting this error: The instruction at "0x241f94f7" referenced memory at "0x0d8bf41c". The memory could not be "read". Only on HL2. Then I updated Bios and my original stick would not post again (just as before), but the other newly acquired stick would. But now it (the original stick) does??? (really stumped here.) Now in dual channel my original stick must be in "second" dimm (3 or 4 depending on what slot first module is in) in order to for mobo to post. It will not post in single channel (dimm 1 and 2) or when in "first" slot in dual channel (1 or 2) Right now everything is OK, no more messages etc. The sticks are in dimm 2 and 4 rather than 1 and 3... (don't know if this can potentially make difference or not but its working and I don't want to mess w/ it.) Mobo settings have been manually set to 2.5-3-3-6 and Disabled CPC (read somewhere that 512 sticks may need CPC disabled in DFI Mobos?) and the Trc has been set to 11 rather than what should normally be 9 (I think.) Am I taking a performance hit here? Could there be a glitch in the one module? Did a Windows Memory diagnostic (is this the same as memtest?) and found no errors in all tests (standard and thorough.) Any suggestions for optimal performance MOBO settings? Should I put the modules in Dimm 1 and 3? One more note: When using CPUz or Sandra to detect memory timings, there is a discrepancy in the default timings (SPD) for each module: 2.5-4-4-8 for slot 1 and 2.5-3-3-8 in slot 2 (200 MHz.) Is this normal? Shouldn't they be the same? Heres some info...
