Anyone successfully running 1866 DDR3 memory in their mx600?

Hi Folks,

I configured my M6600 with 4GB of memory from Dell, and purchased 16GB of Kingston HyperX DDR 1866 memory to populate it after the fact. After I was happily computing away, someone on here in the M6600 owners thread mentioned that the M6600 only supports 1600MHz modules. It never occurred to me to check, I figured the laptop would only run the memory at the speed it supported, and it was running it at 1866MHz.

Fast forward a couple of months and I start getting BSODs and random shutdowns. I break out memtest86+ and, sure enough, I get errors in a very small area of memory (9080MB mark, don't have the actual address handy). Not knowing which DIMM this correlates with, I move down to two modules and start swapping around. I don't see another error until I'm back up to four modules...and despite them all being in different locations, the errors occur at the same portion of memory.

Is it possible to force the system to run these at 1600MHz to see what happens? Can I modify the CAS timings or do anything else, or should I just sell these puppies and purchase 1600MHz memory?

Thanks!

 

i read other thread regarding alienware series and lenovo w520 running these ram without a problem but from what i understand the gain wasnt worth the money so i go for the 1600mhz.
anyway my suggestion is to upgrade to the newest bios if you havent already ?
and may try to go into bios setting to see what setting you can change ?

also i think it bad ram because u run it for couple of months before anything show up. that mean the system is fine with the 1866mhz.

 

If the slots problem has not resolved the situation, then I think you got bad RAM Modules. Ask Kingston for some replacements. Then again, I think that the M6600 only supports up to 8 GB of DDR3-1866. However, considering it has been working for you for a few months shows that the laptop has no problems with the RAM, but the RAM itself is starting to show signs of faultiness.
