Bad Twinx CMX512-3200XLPT module

[tomkelso2003]

Hi,

 

I bought a pair of twinx CMX512-3200XLPT memory modules and

was thrilled with them. So, I bought another pair for a new system

that I am building.

 

I am not having good luck with this second pair. I tested the memory

with memtest86+ ver 1.5 and the pair got errors. So, I tried the test

on each module one at a time. One stick works perfect and one stick

fails on most of the tests (2,3,4,...) giving the error bit as bit 1 ie.

00000002

 

I have the dimm overvoltage at +0.2 volts. timing is at 2-2-2-6 on

a Gigabyte Ga-7VT600 1394 motherboard with an AMD 3000+

cpu with 333 front side bus. Memory bus is on auto but runs at

400. I don't think this can be anything but the memory module

as my good twinx pair works perfect and one of these modules

works perfect. I tried reseating the module but still fails.

 

twinx specifics (on each module):

CMX512-3200XLPT XMS3208v1.2 0453024-2

XMS3200 512MB 400Mhz 2 2 2 5

 

Can I get an RMA for this twinx pair ?

 

Thanks,

Tom

Please set the memory Frequency at 1-1 or 100% and with this chipset If you install more than one module you may have run the memory at DDR266, please check the spec. In addition, I would suggest setting the Dim Over Voltage control to +.2 Volts and set the Rass to Cass to "3" and test the modules one at a time with http://www.memtest.org to be sure.

OK, got some time and did some memory testing...

Set the memory frequency at 1-1 or 266 Mhz (DDR 333).

Set the Dimm Over Voltage to +.2 volts = 2.7 volts.

Set Rass to Cass to 3.

 

Result: The each memory module passed the memtest86+ V1.5

for 3 passes. The memory appears to work well as DDR 333 memory.

 

However, since testing each memory module one at a time gives

one available memory module free for other testing I tested the

memory in my new system.

 

Motherboard: Gigabyte GA - K8NS Ultra-939 Bios ver F5 (latest).

Motherboard settings...

HTT = 200

HT freq = 4x

Max Memclock = 200

CAS Latency 2.0

tRCD = 2

tRP = 2

tRAS = 5

Dimm voltage 2.7 volts

 

Result: One memory module tested OK for 4 passes of memtest.

One memory module failed repeadly in test 5 of memtest.

This same motherboard and settings works well with the other

twinx pair that also work well in the GA-7VT600-1394 motherboard

at DDR 400 speed.

 

I suspect that there is a weak memory module in the twinx pair and

would like to RMA the pair for a pair that works at the advertised

DDR 400 speed with 2-2-25 settings.

 

Thanks,

Hi,

 

I tried to send the online form RMA request twice with no response.

I just sent an Email to warranty@corsairmemory.com with the same

information. Hopefully one of these methods will connect.

 

Thanks,
