Upgrading a HP laptop CPU ?

Hello everyone,


My current laptop is a HP Envy J071SF with a 4700MQ, and a buddy offered to give me a 4900MQ from his old laptop. My question is, knowing that they're socket compatible, that there is/was a Envy 15 with a 4900MQ, that bios mods on HP laptops are a b****, etc, would it be as simple as dropping it in, repasting, and tadaaa, or would there be an issue bios-wise ?
Considering I'd be getting it free, this would be a temporary thing until I get a new laptop mid-2016.

Thanks in advance..

 

If it really is a drop in replacement you'll be seeing ~15 to ~17% (single/multicore) improvement from what you now know.

But, nothing is free. The 'cost' you face is the risk of doing damage to your existing platform and exchanging a good/known solution for an unknown quantity (what is the quality of this 4900MQ and how much has it been abused) on your only existing setup.

Looking at the top mobile cpu's today here, I can see that the 'free' processor ranks at #121 today (already), while yours is currently #180.

When you're comparing your current setup (or the i7-4900MQ upgrade) in about 9 months time with the Skylake platforms freely available, they will be placing far lower on a that scale and the benefit of switching today would only be if you dropped it in and started enjoying it immediately until you upgraded platforms in 2016 Q2.

Myself? I would thank my buddy and use what I had instead.

There is more to a platform than mere raw performance. Stability, reliability and dependability are right up there too.

Good luck.

 

You should be fine... BIOS might not support it but should work, who knows? No harm in trying.. I would repaste with some good Gelid GC Extreme/IC Diamond and keep a look out temps wise... If it doesn't work, sell it and keep the 4700MQ... Never say no to a free gift

 

Hmmm, I'll give it a shot then, but I'll probably end up reverting back to the 4700 if it starts heating up too much.

 

I'm curious to hear how things go. Looking forward to your updates.

Works fine so far, heat doesn't seem to be too much of an issue compared to how my 4700 was faring, might need to hack off parts of my laptop's casing if I start playing games again.
Keyshot rendering seems to work fine, not a big boost in time gain, but a welcome one at least.

 

A more relevant question... do you have an SSD in that laptop? If not, then I highly suggest that you get one.

An SSD is the single upgrade that will give you the most bang-for-your-buck in terms of increasing performance and extending the longevity of your laptop. Dropping $200 on an SSD will give you FAR more of a performance boost than any CPU or RAM upgrade ever could.

 

Yep, that was probably one of the first upgrades I ever did. Got a 750Gb 840Evo a year ago, I've had it live through two laptops so far. Expensive, but definitely worth the cost.

 

lucky person; I'd love to have a "spare" 4900MQ (especially one that OCs with less heat gain) given to me
