TWIN2X4096-8500C5DF failing memtest at recommend settings

[tighey]

Hi,

 

I'm getting memtest errors for the above memory with my bios set to the following: -

 

SLI-Ready Memory: Expert

- CPU Freq MHz: 3600

- CPU Mutiplier: 9x

- FSB (QDR), MHz: 1600

- MEM (DDR) MHz: 1066

- Memory Timings:

- tCL: 5

- tRCD: 5

- tRP: 5

- tRAS: 15

- CMD: 2T

- Advanced Timings

- tRRD: 4

- tRC: 22

- tWR: 6

- tWTR: 10

- tREF: Auto (sets to 7.8uS)

- Voltages:

- CPU Core: 1.425

- CPU FSB: 1.3

- Memory: 2.1

- nForce SPP: 1.40

- nForce MCP: 1.50

- HT nForce SPP <-> MCP: 1.20

- nForce MCP Aux: 1.50

 

I've doubled checked and everything is set as per recommended memory timings. I am also running the latest Bios and I've also tried the following timings at both 1.1 & 1.2 memory voltage: -

 

- 5,5,5,15,2T

- 5,5,5,18,2T

- 5,7,7,18,2T

 

However I always recieve the memtest errors. I've also checked the Mobo wiuth my previous RAM (OCZ PC2 6400) and it tested fine. Do I need a RMA?

 

Regards,

Take the over clock off of the CPU and set the tested settings of the modules and test them one at a time with http://www.memtest.org

Hi,

 

Took the OC on the CPU off and tested with memtest and still got memtest errors at any timing setting @1066.

 

Have tested the sticks individually and one is showing errors whilst the other is fine.

 

Its also worth noting that both sticks pass memtest when running at 800MHz & 1000MHz (Defualt SLI timings)

If one passes and one fails then lets get the pair replaced! Please use the On Line RMA Request Form and we will be happy to replace it. Be sure to check the box that says “I've already spoken to Technical Support and/or RAM Guy.”
