I have a Dell Latitude E5570 with an i3-6100u that is a pga.  I am looking for an i7-6820hq or hk but can only find bga.  Can someone please help me.  I also have an Dell Latitude E5430 with an i5-3230M that is also pga and I am looking to upgrade that to an i7-3540M.

 

I would greatly appreciate the help in locating these chips.

Are you sure the i3-6100U isn't soldered? As far as I know all U-series CPU's are soldered.

 

You can get the i7-3540M from ebay but it's not that big upgrade from the i5-3230M since both are the same 2c/2t chips but with different clockspeed (400MHz difference on base clock and 500MHz difference on turbo).

 

Edit: I just googled the Latitude E5570 and it does have a soldered CPU so you can't upgrade it to i7-6820HQ or anything.

I'm not sure that they do exist that was why I was asking.  I didn't really want to do a whole motherboard swap because at that point I should just look for what I really wanted in the first place.

 

I thought the i7-3540 was 4c/8t but if not then there really is no reason to upgrade it.
