MSI CR620 cpu Laptop upgrade ?

Hi,

Have been wading through various sites tryinng to pin down the top'ish cpu I
could fit into my "old" MSI CR620 i3-370.
Talk about confusing ! esp. as MSI, like most Laptop manufacturers don't
provide any specs. in this area.

Anyhoo... cpuZ tells me that mobo chipset is Intel "HM55" ...so I'm left
wondering if it's the "Express" version.
....and cpuZ says my Socket is "989rpga" ...so I'm left wondering which of
the 988A chips would work in there. Not yet been able to work out if Socket
G1 and rpga989 are the same thing !
Rather, Socket G1 / Socket rPGA988A seem to be different to skt. rpga989
but, most of the i-mobile rpga988A cpus up to i5 will work in there ?,
http://en.wikipedia.org/wiki/Socket_G1

anyhoo... do you think that a "Intel Core i5 Mobile i5-560M 2.667GHz CPU -
SLBTS" / "Socket G1 (rPGA988A)"
would work ? (can't find a 580m, in UK on ebay).

any pointers muchly apppreciated.

regards, Richard

Have you actually looked to see if it _is_ socketed? IM (limited) E,
most _laptop_ mobos have the processor soldered directly to them, making
replacement something I'd not like to try, and I do have surface-mount
chip replacement experience/qualification.

Hi, I do have a rpga989 socket on the board ! Most Laptops I've worked on
do not have the cpu attached to the board, ...come to that, I've never come
across one with cpu soldered to board !
My old succession of 8086 and early 80386 boards were like that, 25+ years
ago :-)
.....and I replaced a chip once, years ago, using such a jig, what a pallaver
that was, sudsing all over the place, but, it worked !

I see pictures of your CPU-Z results, here.

http://www.techenclave.com/community...7-help.110387/

*******

Wikipedia has them separated into convenient articles for you.
The first one, is for your i3-370M

http://en.wikipedia.org/wiki/Socket_G1

They stick a "2" in front of the part number
on this socket, making it i3-2370M.

http://en.wikipedia.org/wiki/Socket_G2

You can double check stuff like that, on ark.intel.com .

Changing sockets frequently (moving a keying pin around),
ensures design obsolescence.

And a day will come, where more BGA is used than
PGA or LGA. Intel has threatened solder-down BGA (ball grid array)
processors a year or two ago. It's up to the industry to provide
feedback as to how they like having the freedom to mix
and match at the last moment, removed. Soldering down
a BGA, means having to pay for no socket, so the
bean counters would like that part.

There are already BGA (ball grid array) chips on the
motherboards - the Northbridge and Southbridge are soldered down.
And probably haven't been PGA (pin grid array) for a while.
One person doing an Asus warranty claim, had the
Southbridge on their motherboard replaced, so they
do on occasion do that kind of repair.

It was claimed at work, that there was a facility in my city
that could "re-ball" a BGA. But the price charged was
high enough, it would be cheaper to just buy a new chip.
It was only proposed as a solution if our limited supply
of prototype chips ever needed to be reused. You "re-ball"
a BGA, so you can solder it to another PCB.

So a home experimenter could change out a BGA, and sell
the old one, but it would not exactly be convenient.
The only experimenter who could afford to do that,
is Bill Gates.

Hi Thanks for the links,
http://en.wikipedia.org/wiki/Socket_G1 helped much with my confusion !
The CR620 I have was released in i3 and i5 versions / 2 dies, whereas I've
noticed that the i7's have just one die and seem to require Intels HM65
chipset and Skt. G2,
....also the i3-2310M class cpus, seem to require Skt G2, and have just one
die.
I'll plump for the i5-560m or 580m and hope for the best !

best regards, Richard
