Thinkpad X220 - Cas 11, 1.5V DDR3 1600 memory question

[techtips]

Hey everyone,

I recently upgraded from an older dell laptop to a x220 which I really love. I recently was offered the following memory from a friend of mine for an amazing price.

G.SKILL 16GB (2 x 8G) 204-Pin DDR3 SO-DIMM DDR3 1600 (PC3 12800) Laptop Memory Model F3-1600C11D-16GSQ - Newegg.ca

The price? $60.00

Now currently I have 4 gig's in my x220 but I do a bit of vitalization work/GNS3 simulation so the more memory the better.
The current memory in my system is:

Item Slot #1
Ram Type DDR3
Maximum Clock Speed (MHz) 667 (JEDEC)
Maximum Transfer Speed (MHz) DDR3-1333
Maximum Bandwidth (MB/s) PC3-10600
Memory Capacity (MB) 4096
Jedec Manufacture Name Micron Technology
SPD Revision 1.0
Registered No
ECC No
DIMM Slot # 1
Manufactured Week 13 of Year 2011
Module Part # 16JSF51264HZ-1G4D1
Module Revision 0x4431
Module Serial # 0xFD6056D1
Module Manufacturing Location 15
# of Row Addressing Bits 15
# of Column Addressing Bits 10
# of Banks 8
# of Ranks 2
Device Width in Bits 8
Bus Width in Bits 64
Module Voltage 1.5V
CAS Latencies Supported 5 6 7 8 9 10
Timings @ Max Frequency (JEDEC) 9-9-9-24


Now the memory from G.Skill is CAS latency 11, 1.5V.
From what I recall, it being DDR3 1600mhz, it will downclock to 1333mhz due to my chipset correct?


Would I be safe with this memory as long as it works fine and memtest86 passes it?

Yes run it for a few days on memtest86+ 5.01 and enable the multithreading mode. A single pass of memtest86 is not a good memory test at all because it likely will not detect marginal ram.

It would be because of your CPU. Notebooks will not likely overclock your CPU to run the IMC at a frequency over the stock.

I'd buy it and run it as long as it works. That's a good price.
