BGA-1190 socket: CPUs, chipsets and cooler fit
BGA-1190 is the Loongson soldered ball grid array package that carries 3A5000 and 3A6000 general-purpose processors. It uses 1190 solder balls in a 35 mm by 35 mm package with dual DDR4 ECC controllers and HyperTransport links.

Overview
The package serves Chinese-market desktops and servers from 2021 with LoongArch cores and binary translation for x86 and Arm software. Chips are fixed to the board at the factory.
Processor generations
Who BGA-1190 serves
BGA-1190 targets LoongArch desktops and servers with soldered layouts. Boards with 7A1000 bridges pair the package with DDR4 ECC memory and PCIe expansion. Firmware and Loongnix support come from board vendors.
Memory and cooling
Memory is DDR4 with ECC through the dual on-chip controllers. Thermal design is board-level with heatsinks for 35 W to 38 W envelopes. There is no CPU upgrade path; board replacement is the only move.

Frequently asked questions
Which processors fit BGA-1190?
Loongson LA464 and LA664 general-purpose processors with DDR4 ECC memory, including the quad-core 3A5000 at 2.5 GHz and 35 W and the quad-core 3A6000 at 2.5 GHz and 38 W covered here. Both are soldered and cannot be replaced.
Is BGA-1190 the same as Socket FT4?
No. BGA-1190 uses 1190 solder balls fixed to the board for Loongson chips, while FT4 uses 769 balls for AMD Stoney parts. A soldered chip cannot move between boards.
What memory does BGA-1190 use?
DDR4 with ECC through the on-chip controllers, commonly DDR4-3200 pairs. The board sets the exact speed.
How many PCIe lanes does BGA-1190 provide?
HyperTransport 3.0 links to the companion bridge; PCIe hangs off the bridge chipset.
