You can use any speed RAM in the laptop, as long as it's the right type of RAM.  If the laptop can't run it at that speed, it would simply downclock it, or loosen it's internally set timings, to allow the RAM to run at that speed.  I did a similar size/speed upgrade on my Alienware M18x and it had no issues with it.

If you want to be SAFE, I could get chips the same as what you have now, just bigger size ones, i.e. if you have 2GB, get a 4GB set of the same speed, etc.  That's the safer way to do things.

You already have 8GB RAM, so capacity is not a problem. You have a laptop, which means even if you had the fastest RAM on the market it would still be slow unless you have a SSD. Home applications are not RAM bound, so increasing the memory frequency would only result in a decrease in the size of your wallet and 0 performance gain.

im planning to buy an ssd also. the other reason i wanted i higher amount is to have plenty of ram to use RamDisk.

Is it still overkill.. should i just use ramdisk 4gb / 4gb for the system? if i had 16 gb i could use 8 gb for ramdisk and still have plenty of ram for the system.

so there would be ZERO negative effect of using higher speed ram. if my system does in fact slow it to 1600, would the performance be exactly as if i had a 1600 (with whatever latency that the 1866 ram has for 1600mhz).. no internal losses?

thanks

Indeed, shouldn't be a problem.
