Cmx512-3200llpt

[xrdirthead]

HI,

I have a pair of TWINX CMX512-3200LLPT that had been running fine. Now one stick won't let me boot with it in either with the other stick or alone. I did try the stick in another one of my PC's and had the same problem.

Thanks,

Ed Kenney

Please set the Dim Voltage to 2.7X volts and then set the timings manually to the tested settings for the specific module you have (Cass 2-3-2-6 with the Rass to Cass set to "3"), and then test the module/modules one at a time with 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.

Could you clarify the bios settings for me a bit further. I'm running this exact same memory in a few of my home computers.

 

Asus A7N8X Bios:

Different Asus Mobo: K8V SE

 

Memlock mode:

Thank you very much,

Example for Nforce 2

CPU Freq: 166 MHz

System Performance: User Define

Memory Frequency: 100%

Dim Voltage to 2.7 Volts

Resulting Frequency: 166MHz

Memory Timings: Manual/User Define

SDRAM CAS Latency: 2T

SDRAM RAS to CAS Delay (tRCD): 3T

SDRAM Row Precharge (tRP): 2T

SDRAM Active to Precharge Delay (tRAS): 6T

 

And with AMD 64 platform

Dim Voltage to +2.7 Volts:

CAS Latency CL=2.0

Row Cycle Time tRC Bios Default

Row Refresh Cyc Time tRFC Bios Default

Ras# to CAS# delay tRCD 3

Row to Row delay Bios Default

Min Ras# Active Time tRAS 6

Row Precharge Time tRP 2

Write Recovery Time Bios Default

Write to Read delay Bios Default

Read to Write Delay Bios Default

Refresh Period tREF Bios Default

Enable 2T Timing Disabled

Then test the system with http://www.memtest.org and make sure it's stable! If you have problems, I would set Enable 2T Timings to AUTO and test it again!

Thanks!

Seven out of eight passed. I do need to RMA one.

Thanks again,

If one is failing then yes, but if you are getting errors with both that might suggest some other problem.

I tested each module by itself and had only one fail.

Let's get them both replaced. Please follow the link in my signature “I think I have a bad part! Or *New* Tech Support Express” and we will be happy to replace them or it!

Thanks! I did request an RMA and put 228450 for the link to this thread.

O.K. please let us know when you get the new modules.
