My M6500 cant got ram bus 1600 even cpu 920xm???

i confirm, you are right, i tryed this KHX1600C9S3K2/8GX today and amazing, bus 1600 mhz active and then i removed them, put pnp ram back the first time when i start laptop, it's still bus 1600 but restart it come back 1333, hic, (. i bought pnp ram and cant return, now the problem, how can i active bus 1600 profile in my pnp ram? help me pls.

 

Here are the specs for the ram you tried first (KHX1600C9S3P1K2/8G).

PnP JEDEC TIMING PARAMETERS:

• DDR3-1600 CL9-9-9 @1.5V
• DDR3-1333 CL8-8-8 @1.5V
• DDR3-1066 CL6-6-6 @1.5V

That profile (1600) is already included, but the Dell BIOS doesn't appear to support that speed for PNP Memory. I guess you might be able to have the ram reprogrammed for that profile only, but you have a good chance of ruining the RAM, or having the laptop still not recognize it anyway.

Note from Kingston: PnP implementation is only possible in configurations that include a BIOS that supports the PnP function. Your maximum speed will be determined by your BIOS.

Honestly, I'd either resell the RAM or hang on to it for another laptop.

 

thankyou very much for helping me..
