dalgo64 Posted October 15, 2006 Share Posted October 15, 2006 I did a bootable Windows Memory Diagnostic test and the memory has failed all the tests. It is Corsair TwinX XL 2xCMX 512 3200 400Mhz, on an AMD Athlon 64 3500+ and ASUS A8V Deluxe motherboard. I get error messages: svchost.exe the instruction at 0x7c9105f8 referenced memory at 0x00000010 and the memory could not be read. I am in Perth, Western Australia and I bought the modules in December 2004 from VTech Industries http://www.vtechindustries.com.au What do I need to do to fix the problem?

Corsair Employees RAM GUY Posted October 16, 2006 Corsair Employees Share Posted October 16, 2006 Please make sure that you have the latest bios and then load setup defaults and set the Dim Voltage to 2.75 volts and then set the timings manually to the tested settings for the specific module you have, and then test the module/modules one at a time with http://www.memtest.org! If you still get errors, please follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it! However, if you get errors with both modules that would suggest some other problem and I would test them in another system or MB to be sure. In addition, with this MB you have to disable legacy USB in the bios when running any memory test. Link to comment Share on other sites More sharing options...
dalgo64 Posted October 17, 2006 Author Share Posted October 17, 2006 Thanks for your help and your reply. I have Asus A8V Deluxe, AMD 64 3500+ and Corsair TwinX XL CMX512-3200XL XMS 320 V1.2. My Bios is 1017. Here are the settings I set: Burst Length 4 beats CAS (CL) 2 TRAS 5 TRP 2 TRCD 2 TRRD Auto TRC 7 TRFC 10 TRWT Auto TWCL Auto TWR Auto Memclock to CPU Ratio 2:1 DDR400 Async Latency Auto DDR Voltage 2.8 (max) CPU FSB 200Mhz V link 2.5 PCI Latency Timer 64 Software memory hole Disabled Bank Interleaving Auto The 2T timing setting I cannot find! Are all the above correct? I am still getting the "cannot read memory" error on boot-up in Windows. I must say the system seems to work faster!

dalgo64 Posted October 18, 2006 Author Share Posted October 18, 2006 I followed your instructions and both modules still fail Windown Memory testing utility. What next? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 18, 2006 Corsair Employees Share Posted October 18, 2006 Let's get them or it replaced. Please follow the link in my signature “I think I have a bad part!

dalgo64 Posted October 19, 2006 Author Share Posted October 19, 2006 Thanks for your reply, I am waiting for the "RMA" to send the modules back for replacement. What do you mean by: "Please note, you are posting from the forum!"? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 20, 2006 Corsair Employees Share Posted October 20, 2006 When you submit the RMA there will be a place for additional comments just let them know you spoke to Ram Guy other wise they might suggest the same steps we have already done!

dalgo64 Posted October 22, 2006 Author Share Posted October 22, 2006 I changed the settings as instructed and Memtest86 v3.2 shows no errors. I still get the "svchost.exe error: memory cannot be read at address such and such..." when loading Windows, but otherwise no memory problem. The system seems to lock-up with 2.8v so I changed to 2.7v. Is this memory ECC or not? Also where do I get some guidance for all the BIOS settings? And overclocking? My current reads in CPU-Z are: Frequency 200.5Mhz FSB:DRAM = CPU/5 CAS 2 RAS to CAS 2 RAS Precharge 2 TRAS 5 TRC 11 Command Rate 1T DRAM Idle timer 16 clocks Are these ok and where can I learn more about these? Best Regards and thanks for all your help. Dalgo Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 23, 2006 Corsair Employees Share Posted October 23, 2006 I would try and set the Command Rate to 2T and set the memory Voltage to 2.8 Volts! Link to comment Share on other sites More sharing options...
dalgo64 Posted October 24, 2006 Author Share Posted October 24, 2006 I set voltage to 2.8v and 2T. CPU-Z readings: CPU: Core speed 1002.5 Mhz (Cool N Quiet enabled) Multiplier x5.0 Bus Speed 200.5 Mhz L1 Data Cache 64KB (should be 128?) L2 512 KB Memory: 200.5 Mhz FSB:DRAM CPU/5 CAS 2 RAS to CAS 2 RAS Precharge 2 TRAS 5 TRC 11 Command Rate 2T Dream Idle Timer 16 clocks Burst Length should be 8 beats or 4 beats? I can set V-Link voltage to 2.5 or 2.6v I can set AGP Voltage to 1.5 or 1.6v DDR is set to max which is 2.8v It seems to crash when I set voltage to 2.8 and 1T, but with 2T seems to be ok. When it crashes, the mouse locks-up and I have to restart. On the other hand when I load Windows, I get one or the other of the following error messages (alternatively): Svchost.exe - Application error The instruction at "0x7c9105f8" referenced memory at 0x00000010". The memory could not be "read". Click OK to terminate the program Click on CANCEL to DEBUG the program The alternative error is: Svchost.exe - Application error The instruction at "0x00000000" referenced memory at 0x00000000". The memory could not be "written". Click OK to terminate the program Click on CANCEL to DEBUG the program Why do I keep getting these errors when Windows XP Pro loads? If I click on OK and the svchost.exe program terminates, then the computer does not work anymore. If I click on CANCEL (to debug the program), the computer continues working, but the Creative Audigy 2Z S Pro Platinum sound card does not work and I have to restart manually the Windows Audio Service (which is not started). I would greatly appreciate your assistance RamGuy. Link to comment Share on other sites More sharing options...
dalgo64 Posted October 24, 2006 Author Share Posted October 24, 2006 Today I got another error out of the blue: Sygate personal firewall: smc.exe application error The instruction at "0x7c9106c3" referenced memory at "0x00c8097e". The memory could not be "written". Click OK to terminate the program Click on CANCEL to DEBUG the program What causes this and how can I get rid of it?

Corsair Employees RAM GUY Posted October 24, 2006 Corsair Employees Share Posted October 24, 2006 Was the O.S. installed on this system? Or was it a carry over install from another system or MB? Link to comment Share on other sites More sharing options...
dalgo64 Posted October 25, 2006 Author Share Posted October 25, 2006 The operating system was installed on this system. I have many partitions and installed operating system Windows XP Pro twice: on the C: partition and the D: Partition. I use the D: partition mostly.

dalgo64 Posted October 26, 2006 Author Share Posted October 26, 2006 With the settings you suggested the system crashes after about 5 minutes. I reset all settings to default in Bios and now it seems to work finally, but the memory is not set to the factory default settings! What do I need to do to optimize this system?

dalgo64 Posted October 26, 2006 Author Share Posted October 26, 2006 With the default Bios Settings except for Audio disabled and Plug N Play enabled, I get the following settings in CPU-Z: Frequency 200.5 CPU/11 CAS 2 Ras to Cas 3 Ras Precharge 2 Tras 5 Trc 11 Command Rate 2T DRAM Idle timer 16 clocks Voltage is default Link to comment Share on other sites More sharing options...
dalgo64 Posted October 26, 2006 Author Share Posted October 26, 2006 With Memtest 86 v3.2 there are no errors. However, with Windows Memory Diagnostic (bootable diskette) all 6 tests are failing. The "expected" and "actual" are different, all with the settings you recommended. Does that mean I need to send them back with the RMA you gave me or not?

Corsair Employees RAM GUY Posted October 26, 2006 Corsair Employees Share Posted October 26, 2006 Wait! The minimum suggested voltage for these modules is 2.75 Volts please try and set the memory voltage to 2.8 Volts and you should load setup defaults and then set the tested settings and please use http://www.memtest.org Ver 1.65 to test the system.

dalgo64 Posted October 28, 2006 Author Share Posted October 28, 2006 I tested with Memtest 86+ 1.65, both sticks simultaneously, overnight and there are no errors in the test. All settings of the Bios 1.017 are default except voltage 2.8v, 2/2/2/5 adn 1T/2T, also set PlugNPlay to enabled, Audio to disabled (as I have a Creative card) and security for boot to Enable (antivirus). System crashed with 1T and also with 2T, after a while. By that I mean that the mouse locks up and I have to restart. Not even ctrl-alt-del doesn't pop up. What next?

Corsair Employees RAM GUY Posted October 28, 2006 Corsair Employees Share Posted October 28, 2006 Hard lock would suggest some other issue and I would leave Plug and Play O.S. set to No and try a freash install of the O.S. Link to comment Share on other sites More sharing options...
dalgo64 Posted October 28, 2006 Author Share Posted October 28, 2006 If I leave voltage to 2.7v and 1T/2T to Auto (it goes to 1T), then no crashes! But still getting the "read" or "write" errors. Link to comment Share on other sites More sharing options...
dalgo64 Posted October 30, 2006 Author Share Posted October 30, 2006 Seems to work without lock-up at 2.7v and 2T disabled and other settings 2/2/2/5. Do I still send memory back to check if ok? Link to comment Share on other sites More sharing options...
Wired Posted October 30, 2006 Share Posted October 30, 2006 If it works and tests fine @ 2-2-2-5 @ 2.7V and 2T disabled, then there's no need to send it in. Link to comment Share on other sites More sharing options...
dalgo64 Posted October 30, 2006 Author Share Posted October 30, 2006 Only one thing left then, the memory address "read" and "write" error message, mentioned before. How do I fix that? Thanks for all your help, my pc is MUCH faster now! Hopefully it does not crash again; seems stable so far. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 31, 2006 Corsair Employees Share Posted October 31, 2006 Sygate personal firewall: smc.exe application error The instruction at "0x7c9106c3" referenced memory at "0x00c8097e". The memory could not be "written". Is that the error you are talking about? If yes I would contect the maker of that software as its most likely a driver/software issue.
