Suspect CMX 1024-3200 C2PT

[Paul2007]

I am running two sticks of CMX 512-3200 C2PT with no problems in the last two years on an Asus K8V SE Deluxe mb with an Athlon 64 running XP Pro.:):

I have just bought a new CMX 1024-3200 C2PT but the OS will not load with one 512 stick and this new 1024 stick - POST will run but XP hangs and system crashes.

Have tried the 1024 stick on its own (in slot 1) but POST will not even run.

Have gone back to running the two 512 modules and all is well.

 

Have tried the 1024 stick in another machine which runs 400MHz DDR and it performs exactly the same - will not even run POST.

 

The two modules are V4.2 and the new module V1.6 but it cant be a timing issue as the new stick will not run on its own.

Looks like a faulty module to me, should I return to Corsair via RMA or to my distributor (Aria.co.uk)?

Advice will be appreciated. :confused:

First thing you cannot mix memory with this platform, and if you install more than two module that are double rank you would have to run the memory at DDR200/100 Mhz memory clock. but all of the modules would need to match both in part# and revision. Please try and reset the Bios with just the new module and then load setup defaults and set the tested settings and Voltage then test it with http://www.memtest.org.

Hey RAM Guy,

I down loaded memtest and checked it with my existing two sticks of 512 successfully.

Installed the single 1024 on its own but unable to run memtest as the PC will not fire up at all, same symptons as previously that the pc just sits there doing nothing, the monitor signal led continues to flash indicating that there is no drive to it from the pc.

Took the stick out and refitted the two 512 and rebooted into memtest successfully and then into XP after running long enough to see no errors.

Does seem to indicate that the stick is faulty?

Any else that you can suggest?

You will need to reset the Bios when you change modules especially if you have the settings manually set. Just install the 1.0 Gig module and then reset the Bios with the Power and battery removed and see if it will post and let you into the Bios.

Ramguy,

Okay, removed the on board battery for 5minutes but will not POST, so I again removed the battery and changed the mb jumper to Clear RTC RAM settings, changed it back and refitted battery.

System will still not POST, so removed the 1gig and refitted the two 512 modules, I can enter BIOS, the sytem reports a failure due to 'overclocking', so I reset everything manually including 2.5-3-3-6, 2.7V and DDR400 memclock speed. Everything works fine, so again refitted the 1gig and still will not POST.

Boy am I confused, is there anything else that you can suggest? :confused:

Thanks for the help so far!
