I have a Lenovo ThinkPad X230t Tablet I7-3520M. I’m interested in the 16GB (8GBx2), Ballistix 204-pin SODIMM, DDR3 PC3-14900 memory modules. This link for one 8GB of those modules states it will fit the X230t (http://www.crucial.com/store/mpartspecs.aspx?mtbpo
The 1st part of my other question is will the PC3-14900 RAM be clocked down all the way to PC3-12800 or will I see any improvements? I saw on a Lenovo forum where they used 16900 & it worked w/o clocking down, but did not work for some memory modules w/ fast timings (http://forums.lenovo.com/t5/X-Series-ThinkPad-Lapt
I also heard under clocked RAM runs cooler.
I recall the Crucial advisory tool saying for years that Dell Dimension desktops would only accept DDR 2700 or below RAM, but not DDR-3200. No offense meant towards Crucial as I love their reliable products!
I read multiple forums over the past few months, but then it hit me that this forum was the best place for the answer.
I’m lost on which if any to purchase. Any thoughts and/ or suggestions would be Greatly Appreciated!

Thanks in Advance & Have a Great Day!

Thank you for contacting us today. From what I can find on Lenovo's site your system has a front side bus speed of 1600mhz, so the RAM will clock down to 1600 mhz as you had suspected. Both the PC3-14900 and the PC3-12800 will work the same in your system. The Ballistix sport memory modules do not require the timings to be adjusted. They are set up to do that on there on. There is a price difference between the two to keep in mind since you will not be seeing the full speed of the PC3-14900. Unless you are planning on using these in another system in the future, I would recommend just purchasing the PC3-12800. Both RAM modules will run the same temperature as they do have the same voltage, so there really is no advantage to purchasing the faster speed with this Thinkpad. Please let us know if you have any other questions or concerns about this memory upgrade.
