Re: ThinkPad W520 & Kingston Hyper-X DDR3 PnP 1600MHz Compatibility

Hi Everybody,

 

1) If I get another GB from 1600MHz or 1866MHz speed will it interefere with the original 8G with 1333 speed? does it produce any conflicts?

 

2) Does it worth upgrading to 1600/1866MHz right now or not?

 

I am considering buying 8GB of same memory installed on the system, unless it is advisable to upgrade to 1600/1866MHz Smiley Very Happy


1) The 1600 MHz and 1866 MHz sticks will fall back to 1333 MHz. They will slow down to the speed of the slowest sticks in the system unless you remove the 1333 MHz sticks.

 

2) It depends on your budget. I just upgraded my 4 sticks of 4GB G.Skill DDR3-1333 to be Kingston HyperX PnP-1866. Resale price of 1333 MHz sticks are not good. I ended up having to pay a huge price gap. 1866 MHz sticks are much (40%) faster than 1333 sticks.

Re: ThinkPad W520 & Kingston Hyper-X DDR3 PnP 1600MHz Compatibility

@ZipZap, I was under that same impression until recently when several good friends lent me a bunch of 16GB kits. Here are the first-hand results from DDR3-1333, DDR3-1600 and DDR3-1866

 

G.Skill DDR3-1333 : http://www.thaithinkpad.com/forum/index.php/topic,17867.msg199582.html#msg199582

G.Skill DDR3-1600 : http://www.thaithinkpad.com/forum/index.php/topic,17867.msg199671.html#msg199671

Kingston HyperX PnP DDR3-1866 : http://www.thaithinkpad.com/forum/index.php/topic,17867.msg199481.html#msg199481

 

I confirm that CPU-Z is reporting DDR3-1866 operating at 1866 MHz in W520 + i7-2960XM.

Re: ThinkPad W520 & Kingston Hyper-X DDR3 PnP 1600MHz Compatibility

Hi folks,

 

Just a quick 2 mo. update. My i7-2820QM W520 is working wondefully with 16GB (4 x 4GB)of Kingston Hyper-X PnP 1600MHz RAM. Did it make much of a difference? Probably not. The memory benchmarks went up a little and some things do seem a tad snappier though. That could be a function of going from 8GB to 16GB though. Just thought I'd let all interested parties know. Enjoy!

Re: ThinkPad W520 & Kingston Hyper-X DDR3 PnP 1600MHz Compatibility

Hi,

 

I have tried to install 1600PnP 2x4GB-kit in my W520 today. This in addition to the original modules. Kit-code is KXH1600C9S3P1K2/8G.

 

I can only get one of the modules working in addition to the original modules. With three modules, I can use either of the two HyperX-modules, so individualy they seem to work fine.

 

I tried different configurations. I first left the original modules in the slots they was in. I then installed the who original modules under the keyboard and the new modules under the pc. Currently running with one original module (DIMM1) under the keyboard and one original (DIMM3) and one HyperX (DIMM4) under the pc....

 

For those running original modules + HyperX - what DIMMs are used for which modules?

* W520 4284-49G (Upgrades: 256GB Corsair Performance Pro & 256GB OCZ Octane) * T61p (Upgrades: 128GB OCZ Vertex, Wi-Fi Link 6300)

These modules no longer function at the rated speed with BIOS 1.37
