Lenovo Z570 CPU Upgrade

Hi huys!I know its asked many times i read the manual, have one old lenovo z570 wonder if any of this cpus will be compatible if someone upgrade it:

 

Core i7-2860QM
Core i7-2920XM
Core i7-2960XM

 

 

All 3 are 32 nm and Sandy Bridge Platform. Any thoughts? I posted this thread because in the past i upgrade it my old lenovo with 16 gigs of ram and lenovo saying that only support 8 and very much like to buy some second hand cpu for upgrade....

p.s. I read the above 3 cpus will fit, bur turboboost for 2960xm will not work or i need modded bios is it true? And fro 2920xm and 2860 turbo will work with this socket G2 on z570?

Hi C0Nt0L!

 

Welcome to the Community Forums.

 

Based on the Hardware Maintenance Manual, page 91 https://download.lenovo.com/UserFiles/UserGuide/en/User's%20guides%20and%20manuals/Z370&Z470&Z570/Le..., you can only upgrade the CPU using the list below.

Re: Lenovo Z570 CPU Upgrade

Are you sure? At least can I upgrade with
Core i7-2860QM, am I able to use turboboost with this cpu?
Someome tested this cpu with z570>

 

p.s. Do I need to change the  AC adapter to 90W?

Re: Lenovo Z570 CPU Upgrade

A quite from e-shop where customer upgrade succefully Z570 not mention nothing about turbo thow...

 

"

I've been keeping an eye out for one of these for a long time- as an upgrade for a Lenovo z570 (its for my little wifey- she wants to play 'No Mans Sky' and her laptop is getting a bit long in the tooth). My reason for holding out as long as I did- was price- I had a target price in my head Eur 90 / US$100 that I didn't want to breach. This pulled chip (pre-used, taken from a working a laptop)- fit the bill on a price basis.  .... after a little bit of a clean up (demineralised water)- I was good to go. Before installing the processor- at the risk of stating the obvious- remove the battery and the powersupply. All-in-all- it took around 8 minutes to remove the bottom plate from the laptop, locate the screws holding the heatsink in situ (several- this laptop has onboard nVidia graphics on the same heatsink chain)- and unmount the pre-existing processor (there is a locking mechanism that has to be unscrewed and it lifts straight out- no force whatsoever needed). Putting a little thermal grease (a pea sized amount), I used Arctic silver- on the core before securing the locking mechanism again, putting the heatsink and fan back on- and screwing the whole lot back together again. The boost in power was immediately apparent- esp. in programmes which were optimised for multi threading (some video coding programmes for example)- the increase in L3 cache being as important here- as the extra cores. The one downside to this upgrade- is the unusual amount of heat the system generates- to say it gets hot is an understatement- you could possibly cook with it......... Processor performance may be reduced by thermal throttling- aka- if the heat system (heat sink fans etc) is not up to removing the additional heat- the system may throttle down the performance of the chip to keep it within certain temperature ranges to avoid damaging the chip itself or other laptop components. It really depends on your laptop- and how easy it is to access the case, fans, heatsink and processor socket- but in general its reasonably easy. If you can this processor at a reasonable price- as an upgrade its a bit of a no-brainer. A fast SSD is my next purchase."

Re: Lenovo Z570 CPU Upgrade

Hi C0Nt0L,

 

Greetings.

 

It general, it should work as shown here if we are to base it from its Intel specifications but one challenge here is the BIOS whitelist if it would allow smooth performance. 

 

Notice the amount of heat generated and the BIOS thermal control may have a challenge coping with it. 

 

I would rather stick to the recommended CPU as per OEM tested and certified CPU. If you have a spare CPU and you are "in" for the challenge then it may be worth a try. I think there is no need to change the adapter since it have the same TDP as current one you have.

 

I hope this helps answer your query.

 

Regards
