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. Shipping was fast- and 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.Read full review

Installed and it performs well so far. The product is, as described, in good condition. I put it into an Lenovo t420 replacing old i5 cpu. Temperatures in normal usage not exceed 55 degrees celsius but it seems normal for an cpu designed to work at 100 degrees celsius. It comes with termal paste but i preferred to use my arctic cooling mx4 instead.

The product arrived soon than expected considering it can drom Chia, but the product looked good and preformed well. I would use them again.

I upgraded my Aspire 5750-2414 to this i7-2860QM CPU together to an Aspire 5750G NVIDIA-GT-520M motherboard in combination. This CPU performs like no other, its exceptional to upgrade on your 2nd gen laptop that has the HM-65 to HM-67 (Sandy Bridge chipset). One thing that I would strongly suggest is that you purchase a 'Laptop Cooler' if you upgrade to this CPU as it does run abit hot especially if you are intending on using it to play games, otherwise this CPU is lighting fast and for a laptop that is going on 8 years, its improved its performance exceptionally.
Verified purchase: No
Very easy to install into my HP Elitebook 8460p. Works perfectly will give a new lease of life to an old laptop.
