Further Lenovo X220 DIMM clarifiation: 1pc DIMM support
https://www.experts-exchange.com/questions/27997244/Can-Lenovo-X220-support-1x-8GB-DIMM-1x-2GB-DIMM.html
Q1:
Pls refer to above EE thread / url. I wish to add a couple more questions:
suppose I manage to find 1pc of 2GB or 1GB DIMM & by inserting just 1
pc into the X220, it works, does this mean 1pc of 8GB DIMM would work
as well?
Q2:
How do I determine my current DIMMs speed? Any commands without
opening up the X220

I'm on 64-bit Win 7.
As this is company work, I wont want to invest in SSD (& the
company won't invest in it either) but 8GB RAM is what the
company agrees to invest in.
I plan to build a RAMDisk to host my Outlook .pst file as I
often had to search thru tens of thousands of emails : this
.pst is now about 4GB & growing. So if I can have 10GB,
it would be a bonus (ie 6GB for the pst file & another 4GB
for Win 7 & other apps)

7200rpm HDD can take more than 3 minutes to search
thru about 100,000 emails, so a RAMdisk is my best bet
(& RAMdisk is faster than SSD). I'll clone a copy of .pst
file to RAMdisk & maintaining one copy in the HDD

So within reason, any memory that is specified and fits is going to work. The memory speeds will be a narrow range and will not have any noticeable affect on the speed of the machine.
You can improve speed of a computer by:
1. Using a 64-bit OS instead of 32-bit.
2. Using a 7200-rpm drive instead of a 5400-rpm drive.
3. Using an SSD solid state drive instead of a hard drive.
4. Using 4Gb or more Gb of memory on a 64-bit machine instead of 2Gb.
Beyond that, the speed of the memory won't make a lot of difference.
Also, for a machine that runs a standard load of software and virtual machines in addition, 8Gb is ample memory. It has never hindered me. My Thinkpad T61p has 8Gb (2 x 4Gb modules) and won't take 16Gb. But I am not hampered.
