Says who? The stock fan will handle with ease in an air conditioned office.

Nobody is mad here, and nobody wants a gaming laptop.

 

Lenovo don't need fanboys defending them on this forum. Just don't sell an extreme edition CPU and lock everything to a point where even a modest 5% OC is not possible.

 

 


I agree I am working on a fix for that. See if I can find an unlocked bios. the xm cpu is pretty much useless.

Re: W520 w/ 2920XM

I've jumped in now Smiley Happy Got a 2960XM off eBay. It works alright on my W520 but I know it *can* go much faster than this!

I got the PCMark Vantage score of 16481 and the PCMark 7 score of 4479. The machine is in optimus mode. Its full specification is

I'm not familiar with PCMark so I really have no idea on the scores. Comments please! Someone on NotebookReview.com mentioned that my score is lower than his W520 + 2820QM + dual-SSD in RAID 0.

 

My Geekbench score is 12110 though.

Re: W520 w/ 2920XM

@huberth,

 

Do you use 4GB Kingston HyperX PnP DDR3-1600 sticks? Do you have any problem stress testing the RAM? A local vendor offerred me to test his 4GB G.Skill DDR3-1600 sticks. It was not stable and the machine always shutdown (i.e., crashed) during Lenovo's System Health and Diagnostics Memory Stress Test.

Yes, I use 4X4GB Kingston HyperX PnP DDR3 1600MHz.

 

Works fine with Lenovo Stress Test.

Got it! I had a chance to test 2x4GB Kingston HyperX PnP DDR3-1600 *and* 2x4GB of the DDR3-1866 one. The results are posted at http://www.thaithinkpad.com/forum/index.php/topic,17867.msg198162. It turns out that the 1600 passes Lenovo Memory Stress Test successfully, giving the WEI memory score of 7.8; whereas the 1866 fails Lenovo Memory Stress Test at mid-way. It gives the WEI memory score of 7.9, though.
