For quite a while ECS has been manufacturing motherboards with on-board processors (processor soldered to the motherboard at the factory). Those boards are marketed under several brand names, such as PCChips, ECS, Amptron and Eurone, just to name a few. PCChips is a brand that belongs to ECS, while Amptron and Eurone are ECS customers (ECS manufactures them boards and simply glue the "Amptron" or "Eurone" tag where we would usually find the ECS one).

In the table below we have compiled a list of all ECS, PCChips and Amptron motherboards that use on-board processors. Boards in the same row are identical. PCChips M810DLU v. 7.5C and ECS K7SOM+ v. 7.5 C are identical, for example. The only difference between them is the color, since boards manufactured to be sold under the PCChips brand are usually red, while those manufactured to be sold under the ECS brand are usually purple.

On the motherboards sold by Amprton, "x" indicates the CPU used, as listed below.

Deceitful Naming

The biggest problem is that ECS/PCChips/Amptron use deceitful naming to classify the processors soldered to their motherboards. It all started with the P6VEM3 v. 3.0 model, which had a 733 MHz VIA C3 processor soldered to the motherboard, on which, instead of the name VIA C3 it read Giga Pro, making the consumer erroneously think that it was a one gigahertz processor, which is not true.
 
The other motherboards listed case use a Duron, an Athlon or an Athlon XP processor, and ECS/PCChips is using deceitful naming for those processors, gluing a sticker to the processor fan where we read something like Pro 2000+, for instance, so you erroneously think it is a 2 GHz Duron, which is not true. In the following table you see the correspondence between the ECS/PCChips names and the real processors. Recently ECS/PCChips started to use also Athlon and Athlon XP processors. When the name has an "A", it is one of these CPUs.
