HP 8460p: upgrade CPU from i5-2520m (Sandy Bridge) to i7-3520m (Ivy Bridge)?

Hi
has anyone tried before to upgrade the Elitebook 8460p CPU?
Are there any known issues with the upgrade to a Ivy Bridge CPU?

I selected the i7-3520m since it's has the same power requirements of the i5-2520m (TDP 35W), and can be found with the same socket (G2 rPGA 988B), but it has 4 cores and a slightly better GPU (HD4000), which also has support for Windows 10 (while HD3000 has not).

here's a comprehensive list of Ivy Bridge processors. I'm also considering a cheap i5-3210m, which would have the only advantage of the graphics over my i5-2520m.

EDIT: I just found out that very few Ivy Bridge CPUs are compatible with my QM67 chipset: http://ark.intel.com/products/52813/Intel-BD82QM67-PCH#@compatibility

. i7-3615QE
. i7-3612QE
. i7-3610QE
. i7-3517UE
. i7-3555LE
. i5-3610ME
. i3-3120ME

And of course I couldn't find any of these on ebay. If you happen to know where these can be found please let me know. I'd like to at least know how much they cost.

Thank you for any help!

 

Even if the chipset supports it, the CPU microcode in the BIOS may not be Ivy Bridge compatible. But why Ivy Bridge? Just get a faster Sandy Bridge CPU, a quad-core maybe.

 

yes just get the sandy bridge quad core

 

Agreed, get the quad core... Will be more likely to work and also cheaper and better....

 

I'd try 3610QM/3630QM/3612QM/3632QM if it's available locally and you can return it immediately. Otherwise, go with lower tier Sandy Bridge quad e.g. 2720QM.

 

Like what other said, I would just with the Sandy Bridge quad cores... because you don't know if your system will support Ivy Bridge CPUs.

 

99,9999999% it doesn't support Ivy Bridge. Find 2670QM as cheap option IMO.
It will help people with way better cooling to sell their CPU and buy something faster Seriously, it's circulation of processors in the notebooks. Low-end laptops come with low CPUs. High-end laptops come with average CPUs. Then Low-end laptops get average CPUs they can handle and High-end ones get top processors.

 

Agreed, only one or 2 laptops supported switching between Ivy and Sandy Bridge Processors, mainly Alienware M17x R4 and 18x R2... So it most likely won't work and will be a waste of time... and money lol..

 

TomJGX, HP 4x40s also support both Sandy and Ivy bridge.

 

I would suggest an i7-2720QM, which can be overclocked using Intel XTU, with a proper BIOS support (which is - I admit - an unknown to me).

 

In HP??! Do you really need that? If you don't and you still don't have SSD then buy SSD and buy processor which you will afford afterwards.

 

HP or not, I think it's worth a try. Besides, I don't think the difference in price between i7-2670QM and i7-2720QM would be substantial enough to allow purchasing of an SSD. On top of that, the IMC in i7-2670QM only supports DDR3-1333, while i7-2720QM supports DDR3-1600, plus the latter also supportd VT-d, which can be useful in virtualization.

 

VTd? Yes. Unlocked multiplier plus higher stock clocks? Good. Faster RAM support? I don't think so.
2630qm for 56$ with no bids for now. I think not many people would bid on it so...
2670QM for 44$ with 2 bids on it.
2720QM for 43$ with one bid and 85$ BuyItNow price.

***KING's ITEM*** 2760QM just for 80$ and 2 pcs left!
I guess we have a winner

So question is whether you want to buy low i7 for 56$ or even less (doubt though) or pay ~80$ for way better one. Yeah, 20$ is not so much, true. I would buy 2760QM... till it lasts!

 

Sure thing, however about the faster RAM support...

i7-2760QM is a Sandy Bridge "refresh", a newer i7-2720QM with slightly increased clocks and increased model number, AND partially unlocked multiplier. It's a different (more powerful) CPU than the i7-2670QM you referred to before. In this case I would also recommend the i7-2760QM.

 

1. Excuse me but "slightly increased clocks"? It's clocks are so much increased that it surpasses 2820QM. It adds 300MHz to 3/4 cores and 200Mhz to 1/2. 2720QM vs 2760QM vs 2820QM.

And can you tell me what exactly are you arguing with talking about ancient pretty old technology everybody knows everything about for years (except you don't know about actual RAM support of course)? After I checked nowadays prices and gave my final verdict based on it (2760QM... not a 2670QM which was way before)?
Notice that I give actual links instead of... misty papyri of Sphinx or whatever you can call Intel's half-real half-marketing pages ( don't google that collocation, just made it). I gave you actual proof. Did you follow the link and browse down to see the RAM's speed or not? If it's hard to read text on black I can give more CLICK ME! don't eat me, just click me.

Spoiler: Don't click me! DON'T! It will make all text I wrote about Intel's sheets true! I Warned!

P.S. You could shrink your signature to 4 raws BTW, that will make our debates actually useful
P.P.S. 2720QM is not newer. It's even older than 2670QM if you want to dig to all words.

 

First you suggested i7-2670QM. I suggested i7-2720QM - it might be older, but it runs at higher clocks, its iGPU is faster, is supports larger variety of technologies (vide VT-d) and officially it supports higher speed RAM. What is your problem?

 

I once had the same laptop some years ago, I actually tried to do the same thing. I tried installed a 3610qm and the laptop would not start. I installed a 2670qm later that day and the laptop started just fine.
