Memory timing on XFX 750i SLI

I want to have appropriate memory timing on this mobo. I am using Transcend DDR2 4GB (2*2 GB) 800MHz (1.8V). In CPU-Z software, under "Memory"" and "SPD" I found the following information and memory timing:

Module size: 2048 MBytes
Max Bandwidth: PC2-6400 (400MHz)
Part number:JM800QLU-2G
Serial number:007FCOC

Timings table:

* DRAM Frequency: 400 MHz

* CAS#Latency:6.0

* RAS#toCAS#:6

* RAS#Precharge:6

* tRAS:18

* tRC:24

* Command Rate: 2T

As I am having numerous random freezing with this board (XFX 750i SLI). I read same problems in other boards where people solved them by changing ram timing on their board.

I want to give it last try. In BIOS, DRAM Frequency everything is auto. Should I change memory timing there (based on above mentioned timing table)?

  1. I noticed from the info you provided you did not include the cpu-z voltage listing. If this data came from the memory page ok. Now go back to cpu-z and click on spd and see if the voltage requirement is still 1.8v. If its higher which I suspect you will need to match (typically) this voltage in bios then retest or try your system. Its also possible you may see EPP settings in addition to SPD settings.

    The cpu-z (under spd tab) reports the voltage is 1.8V. But in BIOS, the voltage is set to 1.9v (default) which can not be changed. It's kinda fixed there.

    Will it cause any major problem if I leave voltage to 1.9v in BIOS and change above mentioned timings?
