Sandy Bridge to Ivy Bridge CPU upgrade in the W520

2012-06-08, 12:14 PM

Sandy Bridge and Ivy Bridge use the same socket. All the tech sites say we can do it.

 

What are the implications? With HD-4000 graphics would I now be able to drive 4 monitors? What other possible benefits are there? Power consumption is slightly reduced, speed is slightly increased.

 

What are the chipset limitations and BIOS implications?

 

It's probably not worth the money, but will it work?

Solved! See the solution

Good questions! The answers will probably remain unknown until someone has actually tried.

There will no doubt be massive chipset incompatibilities not to mention the BIOS rejectng the CPU immediately anyway.

Yes, but you never know. People may have luck on other laptop hardware too.

the bios firmware may not support this upgrade. But theoretically it could work, if someone modify the bios firmware.

This is definitely something I'd like to know. Is Lenovo forcing us to get the W530 or will they allow a BIOS that accepts Ivy Bridge?

Heh. CPU whitelists have been around for some time. Probably at some point someone will create a bios mod to support the newer processor in a w520. There could be other issues using a ivy bridge cpu in your w520 but I have not ready anything to say it would not work. I think the new processors also run a bit hotter (I also read they overclock hotter).

Has anyone upgraded their W520 with an Ivy-Bridge processor yet? It should work.

 

See:

8. Ivy Bridge and Sandy Bridge are backward-compatible. 

Intel has a not-entirely-undeserved reputation of forcing people to buy new motherboards every year or every other year if they want to use the highest-performance CPUs available. The good news is that's not the case with Ivy Bridge. Sandy Bridge processors will work in Ivy Bridge motherboards, and vice versa (although, in that case, you may need to update your motherboard's BIOS to ensure compatibility).

I was wondering the same thing in another thread.

 

The key phrase here is " you may need to update your motherboard's BIOS to ensure compatibility".

 

If a BIOS change is in fact required, I have grave doubts that Lenovo will provide such a BIOS.

 

Who wants to be the Guinea pig?

 

Another question is, will Ivy Bridge really make any difference in the W520? It does support 3 displays, but is the system board able to take advantage, etc etc etc.

Ivy Bridge does make a difference:

1) higher performance
2) it uses less power (The Core i7-2700K system needed 166.5 watts, but the Core i7-3700K drew only 136.3- a remarkable change)

3) it has better Intel Graphics

 

 

Perhaps someone from Lenovo can answer the BIOS question?
