w520 cpu upgrade

can i upgrade my cpu from, 

 i7-2720QM to Intel i7 2920XM 2.5G 8M, I have read some discussion about thermal performance.

at the moment I have installed 32 gb of ram at1600 mhz, but i have the feeling that my 2720 do not really support it, up grading the processor my system will benefit ram "wise" awell?

 

i used my computer moslty for 3d cad and rendering, some of the application I used the most do not support multy treads, that is why I wont the maximum cpu power per core.

 

thank you in advance

Re: w520 cpu upgrade

First, I do not think it will affect RAM speed, other than the benefits from a larger cache. The 2920XM (2960xm is even faster) is 55w TDP and will need a different fan to help with the extra heat. Fan part numbers from manual are 04W0437, 4W1574 or 04W1575.

Re: w520 cpu upgrade

There will be no effect to the ram, the only benefit from this upgrade is a slightly higher clock speed and 8MB cache instead of 6MB. The downside is that the 55W processor will run hotter and thus will need the more powerful fan/heatsink, and it will run hotter, albeit not a lot, but the fan will most certainly have to work harder on keeping it cool resulting in more noise.

 

A much better performance upgrade rests in SSD technology than a CPU upgrade on an already almost top-of-the-line machine.

ThinkStation P500 - Xeon E5-1650v3/32GB // ThinkPad P70 - Xeon E3-1505M/32GB
ThinkPad W540 (20BG) - i7-4800MQ/32GB // ThinkPad W520 (4282-W4Q) - i7-2720QM/32GB
ThinkPad T450s (20BW) - i7-5600U/12GB // Yoga 900 - i7-6500U/8GB
ThinkPad T61 (7665-CTO) - T7700/4GB // ThinkPad T60p (8741-C2G) - T7400/4GB

Re: w520 cpu upgrade

thank you for the reply, 

I allready have a ssd on my device, however something I require more power specially for rendering and conmplex computation single core based. I really do not want to have an "instable system" as I am often usign it for long hours.

how does more cache will benefit my system? is there something else I can do?

 

thank you

best regards

Re: w520 cpu upgrade

Those 3 fans I listed are all for 55w CPUs. I think they are simply different manufacturers. I would have no preference.

Re: w520 cpu upgrade

Check the part number of the fan already installed. I took delivery of a W520 a little over a year ago and it was shipped with the 55 watt fan.
