Micro-FCBGA, is this the standard?

I was wondering about CPU upgrades on my recently purchased Dell 1420.

Does anyone here know if Dell uses the Micro-FCBGA convention for their Core 2 Duo?

And is it truly soldered to the moBo?

 

What CPU do you have in it?

 

When I searched for CPU's for 1420. For example I found the T5250 part #SLA9S which is Micro-FCPGA. If one has Micro-FCPGA I would guess all would? The Micro-FCBGA is #SLA9SM. I don't think they do. Here is a link to Intel if you find a part # telling which it is.

 

Micro FCPGA is soldered.

 

That's impossible. You can't solder pins, they'd be destroyed. Soldering is the exact reason that Intel makes FCBGA CPUs, so they can be soldered into ultra mobile laptops to save room. FCPGA CPU's can always (from my understanding) be removed, however, I'd love to be proven wrong.

EDIT: going with Powerpack's lead, I checked out cpu world and found that the T7250 and T8300 are made in both a FCBGA and FCPGA configuration (of course I knew the T8300 was since I went out and upgraded my lappy). The only way we can really help you out is to know exactly which CPU you have so we can determine whether it's BGA or not. However, if we can't figure it out and assuming you're still configuring your to be laptop, you can always call up Dell and get a most likely correct answer.*

*most likely since the techs may not give you a straight answer like the Toshiba techs did to me. Said I couldn't upgrade but I believed I could since the T5450 isn't even made in a BGA config. I followed through with a disassembly of my laptop and determined I was right.

 

Notyou I totally missed that. I read sgogeta4 incorrectly and just thought his post was irrelevant. Not so completely wrong! CommanderWolf who seems to be one of the most up to date and informed members in this area. If my memory is correct she has said exactly as you ultra mobile is the only place she has seen BGA. I mean from a cost standpoint would not modular be better when options are offered? And warranty repairs would be cheaper if not tied to the MoBo. I mean bad CPU means MoBo GPU and new CPU? Kind of extreme CPU only much better plan. My gut is yea it is PGA. Only wanted to know where OP got BGA idea from? In the first place.

My link in 1st post is Intel all but T7800 Core 2 Duo are offered PGA in quick scan of.

 

It doesnt matter what the socket is called. The processor in the dell 1420 is removable and can be upgraded to a faster core 2 duo processor. However, you may need to update your bios so that yous system can support the faster processor, and possibly new process size.

FCBGA6 is different than Socket M processors. Socket M processors are the CPUs with pins and these are removable/upgradeable. FCBGA6, if that is what the 1420 uses, then the CPU is soldered directly onto the motherboard and cannot be upgraded.

 

I am not sure what the discussion here is? BGA are soldered GPA are not what are we in confusion or disagreement about. Do you know what BGA and GPA mean? I feel this thread is really drifting away from any grounding in reality very fast. But it did not start well as I think maybe OP only worried what if he has BGA with no information. Well to answer OP on original question with so much speculation and no clue on his part. If BGA you are SOL but not BGA so why are we even having this discussion?

sgogeta4 please just use my Intel link and see that M and P come as both and your distinctions well? I am lost. Well because they are incorrect.

 

You're kinda right and wrong. Socket M is the interface that the CPU uses and a further breakdown of that is the BGA and PGA format which determines the upgradeability of the CPU. You're second point though is exactly right, we're just stuck at this point wondering whether the CPU that Dell uses is of BGA format or not. My suspicion is that it's PGA since they are offering multiple CPU's for the same MB.

 

I believe it's the 1.5 Core 2 Duo.
Not the best in the bunch, but it was for my Gf and her demands are quite low.

 

If it's a 1.5 GHz C2D it'll be one of the following: T5250, L7400. The T5250 is PGA and Socket M (? wikipedia says P) so it is upgradeable while the L7400 is BGA so that can't be upgraded. However, I'd believe it's a T5250 (based on the info you gave me now), to be sure, download and run CPUz and post a screen if you can't figure it out. If it is, then you can upgrade to any other Socket M(P?) processor that has the same thermal envelope as the T5250.

 

Notyou is correct if Intel site is correct 5250 is not offered as BGA it is PGA and therefor snaps in snaps out. 1420's are Santa Rosa notebooks that means socket P not M. 1420 never offered Low voltage CPU so not the L7400. Yes you can upgrade CPU. TDP is 35w so any socket P will be fine with the exception of X9000 and X9100 but the $851 price tag likely to cause as much trouble as the 44w TDP of those two.
