hi, I have an intel DH55PJ mobo and an i3 540. i currently have a 4gb 1333mhz ram.

is it okay to put 1600mhz ram on that board? i am planning to upgrade my system one by one. the first thing i have decided to upgrade is the RAM. i will upgrade to an i5 haswell later on.

Works fine, all DDR3-SDRAM DIMMs support operation at the next step under their rated clock speed, and usually with slightly faster timings.
- So much so that the initial access is actually slightly faster; even though the overall throughput can be less.

You might want to consider DDR3-L for lower power consumption even.

Mixing speeds is not an ideal option considering your system supports higher speed DDR3 memory. If you mix higher speed memory with the lower speed then the highest speed will default to the lowest speed memory installed in the slots. But regardless of the speed being downclocked the memory will work.

If you need value RAM then try these:

Crucial.com
Memoryx.com
Kingston.com

Good luck.

Can put 1600 sticks in, wouldn't recommend mixing with the current sticks...Any time you mix sets of DRAM even of the same model it can be problematic

i am not using the 1333 ram anymore. i am just buying a 1600mhz ram in preparation for my CPU MOBO upgrade. i am just concern if a 1600mhz RAM will work on my current mobo. i am planning to use it for the mean time while saving money for the new CPU and mobo

Then sure, didn't want you wspending, then having to return, if they can't run at full 1600, drop to 1333 and tighten your timings (first 3 by one - i.e. if spec is 9-9-9-24 change to 8-8-8-24 at 1333
