Re: W520 w/ 2920XM

nibs, the 2920XM costs that much more because the multiplier is unlocked. That is the end of it.

Re: W520 w/ 2920XM

We use top of the line, overclocked, premium priced hardware because our software typically cost >20 times as much per seat.

Re: W520 w/ 2920XM

Chaaau, single-fan laptops aren't designed to run the i7-2920XM and Quadro 2000M simultaneously at full speed for any length of time. Such laptops have to throttle down the speed, simply because a single fan (especially in a 15" form factor) can't dissipate all the heat that those processors generate when running at full bore. So the throttling profile limits their performance, which is likely why you can't overclock the i7-2920XM (and which may include mechanisms to thwart programs like ThrottleStop). You're more able to run those processors at full speed (and overclock them) on a laptop having a dual-fan cooling system. I just spec'd out a system today, for example, for a fellow engineer who wanted to do something similar, and we had to go dual-fan.

Good luck!

Re: W520 w/ 2920XM

I compared the W520 w 2820 and 2920 models.

 

The w520 with i7-2920 uses a different fan/heatsink which was louder (even when idle) than the one in the 2820 (at least in the 2 units I compared)

 

For only that reason I decided to stick with the 2820.

Re: W520 w/ 2920XM

Business laptops have never been designed for overclocking, they cannot dissipate the heat generated quick enough. Intel's top of the line processors have always carried a large premium over the next few models down. I also highly doubt you work for a company that buys hundreds of laptops and overclocks them, for one thing that would void the warranty and increase the cost of any service contracts. Don't get mad because you bought a ThinkPad when what you really wanted was a gaming laptop, you should have done your research.

Exactly. If my customers want OC I sell them Alienware

Re: W520 w/ 2920XM

The laptop would not hande the overclocking due to the thermal design, it would overheat and other issues.

Re: W520 w/ 2920XM

That's what they said for the W510 and I have overclocked mine without any problems and ran stress tests without any failure. 

 

My results on the W510 overclocking link: http://browse.geekbench.ca/geekbench2/search?q=43892SU

 

I suggest the people with W520 with 2920xm, you should DL throttle stop and see if the TRL and TDP are adjustable.

"They cannot dissipate the heat generated quick enough........"

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.
