Intel LGA 1700 · Upgrade path · Status as of 24 August 2026

Four things, in the order they matter. One: LGA 1700 accepts Intel's 12th, 13th and 14th Gen Core desktop processors, so a 14th Gen part is the fastest desktop chip your board will ever take. Two: if your board is older than the processor you are buying, it needs a firmware update before it will start that processor — and that update has to happen while a processor the board already supports is installed, or through a no-processor flashing feature if your board has one. Three: for a desktop build this socket is finished. Intel's newer desktop processors need LGA 1851, which is a different socket, and no firmware update bridges that. Four: because the ceiling is fixed and it is reachable from where you already are, you may not need to buy a new board at all. A different LGA 1700 board does not raise the ceiling; only leaving the socket does.
The rest of this page is the detail behind those four lines, including the one piece of news that makes this socket look less finished than it is.

Confirmed. LGA 1700 carries Intel desktop processors based on the Alder Lake and Raptor Lake architectures. In the numbering most people shop by, that is the 12th Gen Core series (Alder Lake), the 13th Gen series (Raptor Lake) and the 14th Gen series, which is a refresh of Raptor Lake on the same silicon and the same socket. Those three generations are the whole desktop range this socket was given.
That is the socket-level rule, and here is its limit, stated plainly: a processor fitting the socket is not the same as your board starting it. Whether a specific board runs a specific chip depends on the chipset, on the board maker, and on which firmware that maker chose to release for that model. Two boards with the same chipset from two vendors can differ. Two revisions of the same model can differ.
So we do not publish a list of which processors work in which boards, and we would not trust one that we did publish. Such a list is only correct until the next firmware release, across four vendors and hundreds of models, and being wrong about it costs you a build that will not start. The authority is your own board's CPU support list, published by the company that made it:
Find your exact model, open its CPU support page, and check two columns: whether the processor is listed at all, and which firmware version first supported it. If the processor is not on that list, it is not supported on that board, whatever the socket says.
An LGA 1700 board is not one thing. A B760 board and a Z790 board both take the same processors, and they are not the same upgrade target. The socket tells you what fits. The chipset tells you what you can do with it once it is in.
Confirmed. On this socket the line falls at processor overclocking. B760 and H770 do not offer it, and neither does H610; Z790 does. So a locked processor behaves the same in any of them, and an unlocked K-series part in a B760 or H770 board runs perfectly well at its stock behaviour — you simply cannot push it past that. Our chipset comparison has the tier-by-tier detail with its sources, and it is the page to trust if any other page here disagrees with it.
This is the LGA 1700-specific trap, and it catches people who assume a faster chip brings faster memory with it. A board on this socket takes DDR4 or DDR5, never both, and which one is fixed by the board you already own. The slots are not interchangeable and no firmware update converts one into the other. If you are on a DDR4 board and what is actually limiting you is memory bandwidth, the processor swap will not move it — that ceiling comes off only by changing the board, and at that point you are choosing a platform, not an upgrade. Our RAM and memory guide covers what the choice costs.
One thing chipset tier does not change: which processors physically fit. H610, B760, H770 and Z790 are all LGA 1700 and all take LGA 1700 processors. What varies underneath the chipset label is power delivery, and a high core-count part asks more of a board than the processor it replaces. That is a board-by-board question we cannot answer generically, and it belongs in the same place as everything else here: the manufacturer's page for your model, and our review of it if we have one.
This is the step that ruins weekends, and on LGA 1700 it catches one group in particular: anyone still on a 600-series board. Those boards launched alongside the 12th Gen parts, before the 13th and 14th Gen chips existed, and a board that shipped before a processor existed does not know how to start it. A 600-series board will take the newer generations, but a firmware update may be required first. A 700-series board is the easier case, because it launched with the later parts already in its support list — which is still not a promise about your specific model.
The update that teaches the board has to be installed before the new processor goes in — which normally means installing it while a processor the board already supports is still in the socket.
If you have already swapped the chip and the board will not start, there is a second route on some boards: flashing firmware from a USB stick with no processor installed at all. The feature has different names. ASUS calls it USB BIOS FlashBack, MSI calls it the Flash BIOS Button, GIGABYTE calls it Q-Flash Plus, and ASRock calls it BIOS Flashback.
We are not going to tell you whether your board has it. The feature varies by model and by board revision within a model, and we have not verified it per board. Look for a marked USB port and a small button on the rear panel, and confirm it on your board's own product page. Our review of your board, if we have one, records what the manufacturer publishes for it.
Two related non-claims, for the same reason. We do not print a minimum firmware version for any processor, because published minimums disagree between vendor product pages and vendor release notes and we have verified none of them per board. And we do not tell you a firmware release is safe; the release notes for your model do.
The mechanics of doing it — the USB stick format, the filename rule, what happens if you interrupt it, and what gets reset afterwards — are in our BIOS update guide, and the no-processor route in particular is covered there.
Confirmed. For a desktop build, 14th Gen is the ceiling. Intel's newer desktop processors do not use this socket: LGA 1700 was succeeded by LGA 1851, and a Core Ultra desktop part needs an LGA 1851 board. There is no adapter and no firmware update that changes the physical socket. If you are shopping on the assumption that the newest Intel desktop chip drops into the board you own, that is the assumption to correct before you spend anything.
Reported. There is one piece of news that makes this socket look less finished than it is, and it is worth knowing about so that a headline elsewhere does not throw you. Intel has put new silicon on LGA 1700 since the 14th Gen parts: Tom's Hardware reports a P-core-only family called Bartlett Lake, with up to 12 cores, that targets embedded applications. Notebookcheck, reporting a tipster's SKU list, writes that the line “is now intended to serve edge computing and industrial clients” and that the chips “will not be gracing the consumer segment”, adding that anyone who did obtain one most likely could not run it on a consumer motherboard. We have marked this Reported rather than Confirmed because the socket reference we rely on does not yet carry it at all.
What that means for you is unchanged: the consumer ceiling on this socket is 14th Gen. Parts sold into embedded and industrial channels are not something you can walk into a shop and buy, and a board maker has to choose to support them before they would start in a consumer board. We will re-check that position on the cadence below, and we will say so here if it changes.
Two more boundaries worth being precise about, because both get assumed the other way. An LGA 1700 board will never accept an LGA 1851 processor, and an LGA 1851 board will never accept an LGA 1700 one; the contact counts differ and so does the physical package. And the memory generation does not travel with you either: a DDR5 kit from an LGA 1700 board is not automatically the right kit for the board that replaces it, because speed support is set by the new board and its own memory support list.
Stay on the board you have if it takes the processor you want and the firmware exists for it. That is one processor, one firmware update, no new memory, no reinstall, no case work. For a large number of people reading this, that is the whole answer — and on a finished socket it is a better answer than it looks, because the parts it applies to are no longer the newest thing in the shop and are the easier ones to find used or discounted.
Do not buy a different LGA 1700 board expecting a higher ceiling. It does not exist: every board on this socket stops at the same generation. There are two honest reasons to change boards without changing socket — you want processor overclocking and you are on a tier that does not offer it, or the board you have is faulty or short of the connectivity you actually use. Neither of those makes your existing processor faster.
Move platform when the ceiling itself is what is limiting you. That means a new socket, a new board and, in most cases, new memory, so price the whole change rather than the processor alone. It is the one route that raises the ceiling, and it is worth doing deliberately rather than in stages.
If you do decide to stay and want to see what a step up in board tier actually buys, these are LGA 1700 boards we have written up: ASUS Prime B760M-A WiFi D4 at the entry level, MSI MAG B760 Tomahawk WiFi in the mainstream, and ASUS TUF Gaming Z790-Plus WiFi on the overclocking tier. For the platform comparison itself, see CPU Sockets Explained.
The compatibility and chipset claims on this page are socket-level statements, sourced as follows. Per-board claims are not made here at all — that is what the vendor support links above are for.
The same two tiers we use on other platform pages:
The claim on this page with an expiry date is “14th Gen is the consumer upgrade ceiling for LGA 1700”. A ceiling on a socket Intel has already replaced is the stable kind of claim, so we re-check it every 12 months, and sooner if Intel announces a consumer part on this socket. The owner accountable for that re-check is @DtotheK. As above, a re-check that finds nothing new changes no date on this page.
One thing we deliberately do not do: publish per-board CPU support tables or minimum firmware versions. Those would need re-checking against four vendors' releases forever, and a stale one is worse than none.
