I have a laptop with an AMD Turion x2 RM-74 CPU (Dual core 2.2GHz) with a S1G2 socket (confirmed CPU is removeable), would I be able to buy a Turion x2 Ultra ZM-86 with the same TDP and same socket (S1G2)? They are super cheap on Ebay (about $30) so that would be a good upgrade. I took this off of notebookcheck:

the socket S1 was redesigned to S1g2 (generation 2). It has a separate voltage controller for each energising pin. Hence also former Turion X2 CPUs can be used in an S1g2 socket. However, older S1 socket notebooks cannot be up-dated by a new Ultra CPU.

Here is an ebay link to a ZM-86:

Thanks for your help

the difference will be small i think. and you need to take special care with the thermal paste.

According to CPU Benchmark, the RM-74 gets ~1000 and the ZM-86 gets ~1300 which isnt a bad upgrade for $30. Also are you saying it can in fact be done?

I also have a Turion x2 processor in a toshiba satellite. Mine is a RM-72 and I plan on upgrading to the ZM-86 because of the relatively low cost and also because I don't use the machine much and projects like this keep me from getting bored. Depending on the performance + the RAM upgrade I intend to give maybe it will be marketable and I can get a few bucks out of it. (Also can't find ZM-88 anywhere). I haven't checked if my CPU is removable or not yet. CPUID tells me that it's a Socket S1 638 pin, which leads me to believe that it is but the only true and real way to determine and confirm that is to take it apart and look at it for myself. I see the OP is a few months old. I'm curious to know the results of this if you ever DID in fact upgrade. I'll be sure to post mine. Thanks for reading ^^

I did not end up doing the upgrade, however I know for certain my CPU is removeable ( I have personally checked). I am pretty sure the ZM86 will work
