Upgrading Processor in Dell Studio 1745 (Core 2 to i5)

Jump to solution

I have a Dell Studio 1745 that came with a Core 2 Duo T6600 @ 2.2Ghz

I've researched, I can find nothing to indicate if this is possible however...

I want to upgrade it to the SLBTV - Intel Core i5-540M 2.53GHz/3M PGA988/BGA1288

Now they are both technically Socket P

I know with the 1747 they changed the socket so that it could have an i7, however would the Socket P i5 work with the 1745?

It is running the most updated Bios A04 if that helps.

Hi pcphantom,

The Studio 1745 has Intel Core 2 Duo (Penryn) and Intel Celeron (Merom) processor which is compatabile with Intel Cantiga (GM45 / PM45) chipset. The Intel Core i5-540M 2.53GHz/3M PGA988/BGA1288 will be compatabile with these chipset ( PM 55, HM 57, HM 55, QM 57, QS 57) hence The processor which you want to install it in the system is not compatabile with the chipset.

Yeah I unfortunately ordered after reading another post and then discovered it would not work. Hence I am not looking at upgrading the motherboard.

I looked and the 1747 and 1745 have the exact same physical appearance so I believe the motherboard from all I've read will work.

I am however having trouble locating a motherboard that I know to be compatible.

I looked at J507P on eBay and these listings are so generic it's hard to say.

On the picture one zooms in and it says PGA988 (the Intel socket) right in the picture, but then says it's compatible with the AMD Quad core.

Since I assume AMD and Intel aren't playing so nice they're sharing a socket, I can only assume they are <ADMIN NOTE: Substitute character removed as per TOU>

stock photos.

Any chance you know the model number of the Intel PGA988 board with the AMD graphics?

If I am gonna upgrade the motherboard for this processor, I'd like to at least get a GPU upgrade as well out of it.

I am also looking at LA-5155P, which seems to be from a 1749 so I am uncertain if that one is the same fityet.

I also understand if I upgrade the Motherboard to match this new processor I will also need to upgrade to the appropriate heat sink & fan for both the CPU and GPU as well as get pads. I'm finding these bare dell refurbished motherboards between $40 & $80 which to me is dirt cheap. I already upgraded the keyboard to the back-lit one, added Bluetooth,  added the TV tuner and got the kit to install a 2nd HDD. I figure if I can add a hundred or so dollars worth of refurbished parts and finish this into an i5 system with a good GPU it might be worth upgrading to the touch screen monitor and using this system for another few years and coming out way cheaper than buying a new laptop.

Any advice you can give on this? (besides don't do it lol, I may sound crazy but I'm not).

The 1745 and 1747 are close enough that the boards interchange.  I've never seen anyone swap a 1749 board (newer) into the older -5 or -7 chassis.  You can try it - but you  may find you'll also need to replace at least the bottom shell of the system - the mounting points could well be slightly different, despite the outside appearance.

One place you can ask -- where they will know - is parts-people.com.

Yeah I looked into it and used them to find the heat-sinks for the CPU and GPU. It "Looks" like it's a perfect fit and when I looked up the specs on the 1745 vs 1749 even in dimensions they are identical. I looked up many of the parts on their site and they look interchangeable so I think I'm good. 

Gonna be one heck of an experiment. I'll say this if it works I'll be set. I'll go from a mediocre Core 2 Duo T6600 @ 2.2Ghz to an i5 - 540M @ 2.53Ghz.

The Huge difference will be going from a bad Intel Graphics (Pre-"i" series) with no graphics ram at all to a  1GB Discrete HD 5650.

That is an awfully big upgrade for a total of $115. ($30 CPU, $65 MB, $20 Heat Sinks)

I already replaced my worn out keyboard with a new back-lit one for $20, added Bluetooth for $6, and got the bracket to add a 2nd HDD for $13.

Also, I swapped the RAM out of my ThinkPad before I sold it so it has 8GB now.

I put a 1TB 7200 RPM HDD and have been thinking of putting in a 256GB mPcie SSD that's like $160 and the TV tuner is $17.

I bought this laptop from the original owner when a pawn shop I was working on their computers didn't want to take it for $100, so all in all I think it's been a great investment. 

There is just one thing I can't figure out and that is what parts would be involved in upgrading it to a touch screen.

You think that's overboard?

I was thinking if I invest this money into it I'll have a far better machine than I could ever dream of touching for that kind of money.

Oh and I had made a new thread to ask about it since this one's original question had technically been answered.

Though I went with the 1749 motherboard LA-5155P which only seemed to require changing the heat sinks for the CPU and GPU.

There is no way you'll be able to add an internal touchscreen - there just isn't space for one in the display bezel.  You'd have to hack it with a semi-external rig that would prevent the system from being closed -- and probably end up with a half-working touchscreen.

Working touchcreens need mainboard support and other hardware - this system was never built with one.

According to Dell's web site it was available with touch screen. Even when I pull my system on Support & Drivers there is the option to download all the touch screen drivers, software, etc. I found a touch screen on eBay also that says it's compatible, though on the parts people I also found a cable that appears to be required as well.
