The Intel W680 Chipset Overview: Alder Lake Workstations Get ECC Memory and Overclocking Supportby Gavin Bonshor on March 9, 2022 4:00 PM EST
Earlier this month Intel quietly launched its W680 chipset, the company's workstation-focused chipset for its 12th Gen Core (Alder Lake) processors. Unlike the current generation of consumer desktop chipsets such as Z690, H670, B660, and H610, the W680 adds the capability to use ECC DRAM, including both DDR5 and DDR4 variants. At present, there haven't been many W680 motherboard announcements, although a couple of vendors, including ASRock Industrial and Supermicro have a few options listed. So we're giving you the lowdown on W680, what it has to offer, and what technologies it brings for users looking to build a workstation-class desktop with Intel's latest Alder Lake architecture.
The Intel W680 Chipset: Enabling Alder Lake Workstations
Typically when Intel launches a new series of processors for the desktop market, it releases multiple chipsets with varying levels of features. For its 12th Gen Core family, Intel initially launched its CPUs and premium Z690 chipset, and followed that up with its more affordable H660, B660, and H610 chipsets. In most generations the product stack is rounded out a bit later with a W-series workstation-focused chipset, and finally a variety of Xeon-E series.
Enter the Intel W680 chipset, which is Intel's designated workstation chipset for its 12th Gen Core platform. The Intel W680 chipset is interesting for a variety of reasons, not the least of which is that that it formally opens up ECC memory support for Intel's Alder Lake-S desktop processors.
Intel W680 Chipset Block Diagram
Some of the main features of the W680 chipset include a PCIe 4.0 x8 DMI link, which connects the processor to the chipset for improved bandwidth over Intel's previous W-series chipsets. Other features include support for up to eight SATA ports and integrated Wi-Fi 6E PHY/2.5 GbE MACs for vendors to hook in the latest networking controllers. Intel includes support for 16x PCIe 5.0 lanes from the CPU, with the usual 16/0 or 8/8 bifurcation options.

Other features with W680 include native support for USB 3.2 Gen2x2 (20 Gbps) Type-C connectivity. However, most of the cost and implementation of networking and connectivity still rely on vendors using solutions through proprietary CNVi connections. This is much the same story on regular Z690, H670, B660, and H610 options, the cost for the target market is a massive factor here on what vendors decide to include or omit. The point is the capability is there should a vendor wish to utilize it.
Intel W680: Now with Official Overclocking Support for CPU & Memory
On the whole, there isn't much difference between the W680 and Z690 chipsets when comparing technical specifications. This includes package size (both are 28 x 25 mm), USB, PCIe, and storage support, but interestingly there's a new addition to Intel's latest desktop workstation chipset. This 'new' inclusion is official support for overclocking, which is something both of the previous W-series chipsets – W580 and W480 – omitted.
While the last couple of W-series chipsets allowed users to overclock the memory on supported processors, Intel has opened this up to unlocking the core frequency when combined with its K-series processors on W680. And while this functionality is appreciated, it's admittedly unlikely users will want to significantly overclock an already hot running and high-powered Alder Lake processor, especially on a motherboard that doesn't have a robust power delivery system like Z690 motherboards do.
The point to this is Intel is giving users a choice, and while it sounds nonsensical in practice, it's a pretty big move for conservative Intel. It should be noted that its H610 chipset doesn't support CPU overclocking; it's an interesting shift from Intel's previous standpoint when it comes to overclocking.
W680 Motherboards: What's Currently Announced (As of March 9th)
Despite Intel opting for a slow ramp up for its W680 chipset, a few motherboard options are officially listed, including from ASRock Industrial and Supermicro. As time goes by, and perhaps when Intel pulls the trigger on its obligatory Xeon E-3300 family of processors, motherboard vendors might opt to officially announce more models.
The key element with W680 is that while they offer support for existing Alder Lake-S processors, they are designed around its Xeon series, which aren't usually overclockable. These models generally feature lower core frequencies and TDPs, given their greater focus on reliability versus performance.
ASRock Industrial W680
As it stands, ASRock Industrial has four W680 motherboards listed at the time of writing. This includes one thin-ITX model (IMB-X1233-WV), one mini-ITX model (IMB-X1231), one micro-ATX model (IMB-X1314) and one full-sized ATX model (IMB-X1712).
The ASRock Industrial IMB-X1712 ATX (W680) motherboard.
All of ASRock Industrial's W680 options include support for ECC DDR4-3200 memory and offer varying levels of PCIe 4.0 and storage support. The PCIe 4.0 support depends on the form factor as the ITX sized offerings are limited to just one full-length PCIe 4.0 slot, while the IMB-X1314 and IMB-X1712 have two full-length PCIe 4.0 slots available. For the ITX sized models, both benefit from dual 2.5 GbE, while the larger models have three 2.5 GbE controllers, all of which use Intel I225-LM controllers to power each Ethernet port across all models. It's worth noting that the IMB-X1712 includes two PCI slots for legacy devices.
The ASRock Industrial IMB-X1231 mini-ITX (W680) motherboard.
Both the IMB-X1233-WV and IMB-X1231 ITX sized offerings allow support for Alder Lake-S processors with a maximum TDP of 65 W, while the micro-ATX IMB-X1314 and ATX IMB-X1712 enable users to use processors with a base TDP of up to 125 W. Support and compatibility here are aligned and determined by the base frequency TDP rating on these models.
At the time of writing, ASRock Industrial hasn't announced any availability or pricing for any of its W680 models.
For Intel's W680 chipset launch, Supermicro has listed two motherboards designed around the new chipset. This includes the X13SAE and the X13SAE-F motherboards. These models are ATX in size and include support for DDR5-4400 memory, both ECC and non-ECC DRAM types.
The Supermicro X13SAE ATX (W680) motherboard.
Despite both the Supermicro X13SAE and X13SAE-F featuring the same base specifications, including dual Ethernet, one powered by an Intel I225-V 2.5 GbE and the other by an Intel I1219-LM Gigabit controller pairing, there is one key difference. The Supermicro X13SAE-F includes IPMI functionality which is powered by an ASPeed AST2600 BMC controller and includes a supplementary Realtek RTL8211F management LAN port.
Both of the Supermicro X13 (W680) allow users to use Alder Lake-S processors with a base TDP of 125 W, and both are using a Realtek ALC888S HD audio codec. They share the same connectivity options, including HDMI 2.1, DisplayPort 1.4, and DVI video outputs, as well as three USB 3.2 G2 Type-A and one USB 3.2 G1 Type-A port on the rear panel.
At the time of writing, Supermicro hasn't shared any information regarding the availability or pricing on its X13 (W680) motherboards.

kpb321 - Wednesday, March 9, 2022 - linkSo this is a workstation MB for their standard desktop processors that enabled ECC? That must mean that all desktop process have the hardware to do ECC and it's just not enabled on a standard MB. Seems like the chipset might even be the same silicon as the Z690 as the features seem to be identical other than ECC and vPro support which could both be bios/firmware controlled. Nothing like marketing segmentation just so they can charge you more for something.
mode_13h - Wednesday, March 9, 2022 - link> So this is a workstation MB for their standard desktop processors that enabled ECC?
Apparently so. I followed the links to scrutinize the specs and search for a catch, but they don't even mention Xeon!
It's not uncommon for entry-level workstation/server boards that support Xeon E-series also to support the desktop version, but they will have a note indicating no ECC support for those mainstream CPUs. So, that's what I was looking for, but found no such thing!
> That must mean that all desktop process have the hardware to do ECC
Of course the silicon always has it, because you normally buy them rebranded as Xeon E-series. It's the same CPU, but just with different features exposed and some restrictions (like usually no overclocking).
> Seems like the chipset might even be the same silicon as the Z690
It likely is.
> Nothing like marketing segmentation just so they can charge you more for something.
That the name of the game. The other thing Intel will tell you is that Xeon-branded chips are binned for better stability and reliability. I don't know how much truth there is in that, but I've never seen one fail.
My guess is they're just trying really hard to eliminate reasons for anyone to buy a Ryzen. They matched on core-count (okay, with hybrid cores), surpassed on DRAM and PCIe revisions, surpassed on PCIe lanes, and now they've even surpassed Ryzen on ECC!
I wonder if AMD will follow suit and enable ECC on the non-Pro Ryzen APUs. With rumors that Zen 4 desktop CPUs will *all* be APUs, they'd better do it now, if they hadn't already planned on it!
flgt - Thursday, March 10, 2022 - linkSo does this mean the end of the low end Xeon W and E processors?
AdrianBc - Thursday, March 10, 2022 - linkIt looks like it. The specifications in Intel Ark have been modified to show ECC support for many models of Alder Lake, the exceptions being the models without GPU, with the suffix F, which do not support ECC.
Previously ECC support was the only difference between Xeon E/W and the corresponding Core ix models.
There is no reason to introduce Xeon models now, unless they would have enabled AVX-512, to be differentiated from Core models.
eastcoast_pete - Friday, March 11, 2022 - linkAnd that enabling of AVX512 would be easy enough, as they just have to not fuse that function block off. Which is what Intel announced they'll do going forward for regular AL desktop CPUs. Apparently, they got annoyed that people and some board manufacturers figured out quickly that AVX512 was alive, well and available if one booted with the E cores disabled.
bernstein - Wednesday, October 5, 2022 - linkAs per ark.intel.com all the low end models have ECC disabled. (The 12500 is the lowest end model) So there is still no ultra low-end ecc model. (up until the 9th generation the i3 had ecc enabled).
Real shame intel is still messing up ecc support up big time. wtf? the F models aren't that much cheaper anyway and they could always just limit supply to dies with a defective gpu. also given the w680 cost, only very few current customers would pair that with an i3... And while we're at it why not enable ecc on the z-series chipsets? they already have the same price & features as the w-series anyway! would simplify things for intel, motherboard manufacturers & b2b/consumers without costing intel and motherboard manufacturers a dime. i'd wager because of lower costs they would even make more money.
Foeketijn - Wednesday, April 20, 2022 - linkWhich Ryzen doesn't support ECC now? I have a couple of Ryzen servers running ECC in Asrockrack rackservers.
abufrejoval - Monday, April 25, 2022 - linkThe non-Pro APUs seem to have ECC actively disabled.
Yet since the pro variants based on the same silicon have it, it seems a clear case of exactly the type of fusing/segmentation AMD has been happy to criticize Intel for and a major inconsistency for me.
Per VM encryption is another feature that's currently only supported on EPYCs, while the silicon is all there in all variants of the chips.
The main issue for ECC and encrypted VMs is that it requires BIOS and OS support to function or deliver its full potential and there could be extra licensing cost involved from an external vendor that AMD cannot iron out without too much of a cost impact.
And for that bit of doubt, I'm holding back my flame thrower just ever so slightly.
I'm running my Ryzen 9 5950X on ECC DDR4-3200 because it felt safer at a billion bits of RAM.
I have no idea if a bit ever flipped and was corrected. I'd only ever feel *really* safe, when I could test for it working via error injection. But I'm doubtful such a tool would fit in my budget if it were available widely.
shadowx360 - Monday, May 2, 2022 - linkMultiple people have tested and proven Ryzen ECC support on motherboards like the Asus X570 WS. Windows event viewer shows events with ID 47, which is for corrected bit errors. You can easily forcibly introduce errors by dropping memory voltage or overclocking, Google for specific guides on Windows and Linux.
shadowx360 - Monday, May 2, 2022 - linkP.S. wanted to add that AMD segmentation is different. Non-pro APUs are physically different, as the IMC does not support memory virtualization protection. Pro APUs have a different IMC that block modification of certain MSRs at a microcode level, for a higher level of security. The pro IMCs also contain ECC support, so it’s not like AMD flipped a switch and slapped a label on them. I’d wager it’s more likely because of the monolithic design they decided to shave off as much silicon as possible. Yes it’s segmentation, but for entirely different markets.
