Bad memory stick in VS2GBKIT400C3


Recommended Posts

I have two sets of VS2GBKIT400C3 chips installed in an ASUS A8N-SLI motherboard; one was installed at time the system was built, and the other added last year as an upgrade to 4GB of memory under Windows/XP-32. [Yes; I realize 32 bit Windows will never use all 4 GB; this was done as a prelude to moving to 64 bit Vista].


Settings have been set as per advice in this forum; however the system was never fully stable.


When I dug into the issue, using either CPU-Z or the Nvidia NTune application show the following:


Slot 1 / 3 / 4 --> CAS 2.5 / CAS 3

Slot 2 --> CAS 3


Overriding CAS settings to CAS 3 in the Bios appear to have stabilized the system; have been running for 4 days with no failures.

All of the modules will need to be the exact same part number and revision and the with 4 modules you should set the memory frequency at DDR333 and set the timings manually to Cas 2.5-3-3-7 and I would set the memory voltage to 2.75 Volts and use http://www.memtest.org to test the system.


Current STABLE settings are

333 Mhz


Tras 8

Trcd 3

Trp 3

Trc 10

Trfc 12

Trwt 4

Twr 3


DDR Voltage 2.75


When I was running with CAS 2.5 / Tras 7 had major stability issues.

So I shouldn't be concerned that the SPD ratings on one of the sticks of memory is only CAS 3; while the other 3 sticks are all CAS 2.5 / 3.0 ?


So much for the idea of buying matched memory sticks in VS2GBKIT400C3 packaging!
