In previous generations of Core, Intel did not allow ECC error correction for its core processors, leaving it to the small and large Xeon models. As part of the vPro platform, Intel introduced the W680 chipset, but there are no identical Xeon processors. However, running the core processor on the motherboard with the W680 chipset allows the extra bits to be moved for error correction.
This is the case for both DDR4-3200 and DDR5-4800. Intel describes this in product letter as follows:
“Error Correction Code (ECC) memory support reduces errors and provides a stable architecture and design platform. And when paired with the right Intel Core processors, you get support for the Intel vPro platform, which gives companies the tools to manage and secure their workstations.”
colleagues from hiace online I explicitly asked Intel again and it was confirmed that ECC works in tandem with the core processors.
We already know the W680 chipset associated with it, because it is the Z690 chipset without the option to set the multiplier in the K variants. However, OC storage is still possible. Other than that, the hardware is identical: 1x PCI-Express 5.0 x16 and 1x PCI-Express 4.0 x4 are offered via the processor. Of course, memory is also communicated via the integrated memory controller directly via the processor.
The physical chips are connected via x8 DMI 4.0. There are 12 other paths for PCI Express 4.0 and 16 paths for PCI Express 3.0. There are also SATA, different USB configurations, different storage technologies, network interfaces, and much more.
It is not known when the first motherboards with the W680 chipset will be available. ASRock has already provided some motherboards with the W680 chipset:
