X220: max RAM is 8Gb or 16Gb???

[sniper_sung]

Damn, I wish I had a real reason to put 16gb into this thing...

On a side note, have you noticed a reduction in battery life?

FYI:

Idle power consumption of the whole machine is 2W lower than 8GB (2 x 4GB)!

Load power consumption is the same: ~45W

So I expect no changes to the battery life.

I can't see any sensor readings of the voltage in Everest (AIDA64). The SPD info says 1.5V but that might be wrong.

I've found the bottleneck to be the disk performance years ago, ever since Vmware Workstation 5.5 or even older versions.

I always run VMs on SSDs and never had any disk performance problem - it's already drastically faster than running VMs on HDDs.

Yeah don't get me wrong - im not trying to tell you how to suck eggs here

I've noticed though that if I run a couple of my VM's on the same spindle as my OS then my ssd can stutter sometimes - it's a vertex 2 for all that it matters....it's good that you don't see these issues I spose.

Glad for the visual confirmation of the 16Gb though - im tempted to try it in my t420

Well stuttering of SSD is a common problem, and usually can be fixed by firmware update if it's not a problem of the hardware design.

Intel SSD is very good at handling deep queue of 4k random. So is Micron M4 and C300. I don't have very good impression on other brands though.

I can verify that 16GBytes of memory does indeed work on a Thinkpad T420 with an I7 2640M CPU. Win7 home premium 64bit recognizes the full 16GBytes. Yay!

I was looking at NewEgg.ca and RAM prices for a 16GB kit is about $150 - $200ish. There is a 16GB kit from Crucial on NewEgg that is $780.00. Why is this so much more than the other kits with what seems like similar specs? Interestingly, the exact same kit is available directly from crucial.com for $250. What am I missing?

Found this deal for 16gb memory from dealnews. Will it work? $88

I have KomputerBay 16GB 1600MHz. Right now max 1866MHz is 8GB. If anyone finds 16GB 1866MHz let me know.

When they stocked it, the price was 780. They haven't unloaded it all since the price drop and it may be a long time before they drop the price. My vendor Insight does the same thing as I'm sure many others do.

The Crucial kit on the USA site is at Newegg.com - Crucial 16GB (2 x 8G) 204-Pin DDR3 SO-DIMM DDR3 1333 (PC3 10600) Laptop Memory Model CT2KIT102464BF1339 and goes for $185 USD.

The Canadian site needs to be fixed.

^^ Thanks for the link thors.hammer! I'm going to seriously consider that upgrade if it will be compatible with my ideapad.
