Intel HM70 Express chipset support celerons and pentiums, and doesnt support i3/i5/i7

while Intel HM77 Express chipset support all celeron/pentium/i3/i5/i7

Both support SandyBridge/IvyBridge

People who tried to run a core i3 on a HM70 chipset, reported that it worked fine for 30 minutes then the computer suddenly shutdown, without any alarming temps or anything similar.

Anyway to remove that limitation ? does the chipset have a firmware that can be modified ?

Don't buy a laptop or embedded device and expect to upgrade it. Problem solved.

As soon as a work-around is found, a "fix" will be slipped into otherwise-needed updates, and you'll be back to square one. Since that's a bricked PC, your options are to get something better from Intel, or use AMD.

More evil segmentation from Intel. Soon enough, this kind of crap won't matter, because CPUs won't be socketed or upgradable in any way. (Consumer platform, of course. Expect it to be phased in over the next 2-3 CPU generations. BGA for everyone! /oprah )

Wanted to save money, got the HM70 instead of another chipset as the deal. Later complains about evil company. Priceless.

yes this stuff with the HM70 is ridiculous, it supports at 2.4GHz ivy bridge as long as it's branded as Pentium, if you try to use an i3 the PC is going to turn off after 30 min... pretty ugly.

I don't know of any solution for this problem,

Dear Intel,

If my next CPU upgrade must be embedded then I will have my three current rigs (2 Haswell and 1 Ivy) for a very, very, very long time.

The thing is, .. this is totally new, and was not expected at all, and was not announced enough.

Until hm6x chipset, which supported sandybridge, everything was fine ..

Could bring more life to AMD ??? I will certainly buy more AMD when this happens.

Intels artificial segmentation choises is getting pretty ridiculous, i think it deserves a topic on its own now.

I had a Lenovo that I upgraded to a i3 that would shut off unexpectedly, I ended up putting the B960 back and the issue went away. I never new about this limitation but that would explain the issues I was having and why it was "fixed" when I went back to the original CPU.

You're spreading this lightly substantiated rumor as fact at every given opportunity, yet still claim to not be a fanboy... *sigh*

If you're using a low-end laptop, the number of reasons to not bother trying to upgrade are endless, OP.

HM70 is made for ivy bridge and sandy bridge dual core, latops using it can go up to 35W TDP CPUs, this should be the main restriction, not this stupid artificial lock...


look at their old "Pentium/Celeron" (like T4500) exclusive chipset from around 2008-2009, GL40 or something, no laptop with it was sold with Core 2 Duos, BUT as long as it was a 800MHz fsb model (like T8300, t9500) you could upgrade with no problem, no stupid lock like this... and at a time when the chipset was far more important,

It was a deal struck. You can save x $ on getting this cheaper chipset and we impose locks. Or you can simply buy the chipset that cost x $ more.

All manufactors does this. Hardware and software.

Its funny to see how people feel they are entitled to something more than they payed for. Because it was the enduser in the first place that cheaped out.

the deal is made with OEMs, since Intel don't really sell HM70 for consumers, worked the same with GL40 (with no stupid lock needed), as far as I know.

HM70 PCH uses the same DMI (PCIE) as HM75, it supports the same socket, same type of CPU since it even works for a time, this lock intel implemented is a disgrace, Intel got what they wanted by selling the HM70 combined with cheapo Pentium/Celeron for the OEMs, there should be no need to screw (laptop, not chipset) buyers who want to upgrade CPUs like this...

Edit: nevermind, the OP isn't even the one supposedly having this "problem"

Assuming someone actually was upset by this, I would point out to them that they should probably do their homework before making tech purchases. Kind of strange to blame a manufacturer for a personal oversight.

Intel states fairly clearly what chips HM70 supports.

Oh, and I'm sure that most OEM and their retailers state clearly, up-front, what system logic chipset they use, in order for the consumer to make an informed decision... (snicker).

It's hard enough just finding what CPU a laptop uses.

I never knew about this limitation, nor did I care. When the warranty was up I upgraded from the B series CPU to an i5 as most tech-heads would do. That's when the problems began but I just figured it was either overheating, the board couldn't supply enough power or it just flat crapped out.

I sat it aside and didn't mess with it for a while. Ended up selling most of the parts like the i5, HDD and ram since I planned on tossing it in the trash but found a "free" original B series CPU for it. I decided to toss it back together for grins and the problems went away. I ended up running IBT, OCCT and a few other stress tests on it for days without a single issue so I sold it off assuming I overlooked something when I upgraded to the i5. Now I read this and it confirms what was happening to me, and also explains the issues I was having.

when I decided to buy the HM70 laptop no one else had tested it for an upgrade, but the fact that they anounced the GL40 the same way and it worked with Core 2 Duo anyway, and the fact H61 which is even more basic, or the fact that I know pentium and i3 are the same and should always be compatible made me guess it should work, and it does, that is, until the stupid lock shuts down your computer.

also the link you provided have this diagram

hm70_block_diagram_450x450.jpg.rendition.cq5dam.webintel.450.450.jpg


"Intel Core processor" is not just Pentium/Celeron

maybe they made the diagram before implementing the nasty lock? :whiste:

that's also true, you buy a laptop with a 2020M you know it's ivy bridge and uses the same socket as the i3s/i5s, same architecture, same TDP it would be fair to assume you can upgrade, and the chipset version is not always easy to find,...

So you say the user doesnt know what CPUs are supported. Yet they know if its socketed or soldered on?

he knows what CPUs are supported, dual core ivy bridge and sandy bridge 35W.
unfortunately because of the dirty lock he will get a surprise after half a hour using his upgraded laptop.

before this hm70 chipset, all you had to check:
1. the processors use the same socket (FCPGA988)
2. they are from the same generation (ivy bridge)
3. the one you are trying to upgrade to is released on an older date, to make sure it is bios compataible (i5 3210m: 3 June 2012 -- Celeron 1005m: 9 June 2013)
4. the same TDP, to make sure that the heatsink/fan is enough

Is not clear at all
i use an hp compaq cq58 with i3-2328m !!!!! factory made not upgrade
