Sandy Bridge to Ivy Bridge

[dvz6677]

Hi guys, I want to upgrade the cpu of my laptop (bought 4-5 years ago)...

I have Socket 988B rPGA (PGA988B)

From i5 - 2410m to i7 - 3840qm (compatible with my socket)

I found a cheap one , so the thing is ..I will be able to do that without problems?

And now I have mcpie 2.0 (PCI 2.0 on Sandy bridge), I will have mpcie 3.0 (Ivy Bridge) after the upgrade?, or my motherboard is not compatible with pci 3.0?

Thanks for advanced and sorry about my english.

This will not work, primarily because you're moving from a 35w CPU to a 45w CPU, in a laptop designed to only dissipate 35w. The new CPU will likely overheat.

Try to pick out another 35w CPU.

EDIT: It's also possible that your CPU is soldered to the motherboard. Most Sandy Bridge i5 mobiles were not, but some were. I suggest opening up your laptop and checking before you buy an expensive CPU; soldered CPUs are not replaceable.

Its not soldered I can change it.

So I also can go for i7 - 3632qm or the i7 - 3540m wich are 35 W.

Anyone upgraded from 35 w CPU to 45 W cpu? its 100% will be overheat? I'm a risky guy...

respect the 2nd generation to 3th generation compability? and mpcie 3.0?

Yeah, 100% chance.

There's also a small chance that your laptop might not boot with an Ivy Bridge CPU due to the BIOS not having support for newer chips, but I find in most cases it works.

If the i7 - 3840qm is sufficiently cheap, why not go ahead and try it.
If it does not work as you wish, resell it.
If you have a heat issue, you can probably turn down the maximum cpu utilization in windows power management and still get a boost.

If you have not already converted your laptop hard drive to a ssd, I would do that first.
It will transform the performance of your laptop.

I did a 35 -> 45W (Pentium to i7) in an Acer laptop. Cooling was absolutely an issue - the thing hit 200F and throttled almost immediately under any kind of load. Laptop coolers are just not designed for it.

Fortunately I was able to find a beefier heat pipe from a similar model that fit this particular shell. The chipset supported the i7 without issue with proper cooling.

Ok thanks...I already have a Samsung EVO 840 and I'm happy with that.

I think i will go for i7 - 3632qm, but now the thing I want to know if there is possible that mi mpcie 2.0 work at mpcie 3.0 (I want more bandwith)when I upgrade my cpu, being my mainboard a Sandy Bridge based.

ofc i7 - 3632qm suports PCI 3.0

For PCIe 3.0, you need both CPU and chipset to support it. I depends on what chipset is in your laptop.

 

[dvz6677]

Can't find any info about my chipset supports pci 3.0... sorry

I got these pics about cpu and motherboard:

 

[Ecky]

I think you need a "7" chipset to get PCIe 3.0, e.g. HM75.

However, don't worry, the performance difference between 2.0 and 3.0 is negligible.

 

[dvz6677]

Not for a eGPU using mpcie connector...

I dont want bottlenecks if a mpcie 3.0 is poor, imagine mpcie 2.0...🙁

 

[dvz6677]

In fact is not worth fight for a eGPU... I will go for Desktop PC

I have intel celeron b800 35w sandy bridge, and when i try to boot whit my new i5 3230m ivy it shuts down after 3 sek, what do i do and is there ANY way to make my new cpu work? Same socket
