The CPU of my T530 is i7-3720QM
Add recently I added two 8GB DDR3 1600 dims into my laptop
But sometimes it crashes into blue screen right after bios is booted up and Windows is booting(Win 7 x64 u sp1)
There are two types of error code from the info of Blue screen
2. pfn_list corrupt
Seems it is memory related, I tried to remove one of the DIMM, the blue screen never happens
(I tried to remove one and keep one running for a whole day, and then install it back and remove another one)
And then I tried both the bios build-in memory test app and some 3rd mem test tools (memtest, aida64), but none of them claims any problems of my laptop with those 16gb memory
So I guess the two pieces of memory may not working together well, but except that, is there any other potential root cause?

You need a matched set of DDR3. As speed increases the requirement of a match pair become more crucial. Also all makes are NOT compatible with the system. Some will work and other crash the system.
Getting a match pair from a reputable OEM is best and the only solutions. Over time you'll end up corrupting data on the HD.

He said he added two sticks. I assume he means a matched pair. He is also using a reputable maker and supplied the exact part number for the Corsair sticks which can be found easily at http://www.newegg.com/Product/Product.aspx?Item=N82E16820233264
In theory, those sticks should be just fine.

Yep, those are a pair of Corsair CMSX8GX3M1A1600C10...
The only different I can found from my original hynix HMT351S6CFR8C datasheet is the hy's Cas is 11 clocks while the Corsair is 10 clocks.
I am not sure whether this difference will bring that huge impaction...

Okay... this is of particular interest to me, as I purchased a T530 a few weeks ago with the 'stock' 4GB of RAM, fully intending to upgrade to 16GB after the holidays. Hearing that its not as simple as purchasing two 8GB sticks of DDR3 1600 memory is a little worrisome.
Are there any known-good brands/suppliers out there? I don't mind paying a little extra for trouble-free experience, but one place I was looking at was padding the bill to the tune of >$1000 to upgrade from 4 to 16GB when initially shopping for a T530...

So for 'OEM' stuff this is what you'd recommend?
...x2 of course. That is a bit more spendy (like double) what I've seen comparable amounts of RAM from Newegg.com, etc. but looking at the specs listed for those items like voltage, latency, CAS, etc. and seeing how they vary ever so slightly from one brand/model to the next... I think I might stick with the OEM stuff after all
