Intel Xeon Platinum 8331C
24 cores / 48 threads per socket at a listed 2.5GHz base and 3.5GHz maximum turbo, on the FCLGA4189 server socket. The 8331C is an OEM and cloud-custom part: Intel publishes no product page for it, so this page carries only the figures we can trace to named public records, names every one of them, and confirms the specification against the physical part when you order. Sourced and tested in Hong Kong.

Xeon Platinum 8331C - 24-Core OEM Part
24 cores / 48 threads per socket, 2.5GHz base clock and 3.5GHz maximum turbo, 36MB L3, 185W TDP on FCLGA4189, sSpec SRKHK. This is an OEM and cloud-custom SKU built for hyperscaler and OEM platforms rather than boxed retail sale. The core, clock, cache and TDP figures on this page come from the public Ice Lake Xeon processor list and are labelled as such, while the sSpec is read from the laser-etched marking on the heat spreader of the physical part: Intel's own published SKU list for this generation does not contain this processor number. Note that only the maximum turbo figure is published - no all-core turbo is stated anywhere we could reach, so we do not print one.
FCLGA4189 Socket Class
The 8331C is listed on FCLGA4189, the socket family shared by Intel's 3rd Gen Xeon Scalable server platforms - the same socket as the documented Xeon Platinum 8358P and 8369B. Because Intel publishes no datasheet for this SKU, we do not print a memory channel count, PCIe lane count or a launch date for it: those are confirmed against the physical part and your OEM build sheet at the time of order.

Key Specifications
| Component | Specification |
|---|---|
| Processor | Intel Xeon Platinum 8331C (OEM / cloud-custom SKU) |
| Cores / Threads | 24 cores / 48 threads per CPU |
| Base frequency | 2.5 GHz (listed for this processor number by the public Ice Lake Xeon list) |
| Max turbo frequency | 3.5 GHz (same source). No all-core turbo figure is published anywhere we could reach, so none is printed here. |
| L3 cache | 36MB (public Ice Lake Xeon list); not confirmed by an Intel document |
| TDP | 185 W (public Ice Lake Xeon list); not confirmed by an Intel document |
| Socket | FCLGA4189 / LGA 4189 |
| Memory | 8-channel DDR4-3200 per the public Ice Lake Xeon list; Intel publishes no datasheet for this SKU |
| sSpec | SRKHK - read from the laser-etched heat-spreader marking of the physical part (a sample marked 8331C / SRKHK / 2.50GHz). Intel publishes no document for this SKU. The sSpec SRKHX, which circulates against this model on some second-hand listings, is the sSpec of the Xeon Platinum 8368Q. |
| Intel-published specification | None - Intel's published SKU list for the 3rd Gen Xeon Scalable generation does not contain this processor number |
| Specification source | Intel documentation is not published for this SKU, so the figures above come from the public list of Ice Lake-based Xeon processors, which places this part in its Xeon Platinum dual-socket table with an LGA 4189 socket. As corroboration that it is a non-ARK custom part, Intel's own 3rd Gen Xeon Scalable ARK series page enumerates its published SKUs - including the Platinum 8358P on the same socket - and this processor number is not among them. Only the maximum turbo figure is published (no all-core turbo); PCIe lanes and launch date are not stated by any source we reached and are therefore omitted, and every specification is confirmed against the physical part per order. |
The Xeon Platinum 8331C sits in a category that catches buyers out: it is a real Intel processor number, but Intel does not publish it. It does not appear on Intel's own SKU list for the 3rd Gen Xeon Scalable generation - the list that includes the documented Xeon Platinum 8358P on the same socket - which is the marker of an OEM and cloud-custom part built to a hyperscaler or OEM platform specification rather than sold through distribution.
That has two practical consequences. First, the specification on this page is community-sourced and labelled as such, so treat it as a starting point and confirm the part against your build sheet. Second, if you see this model advertised elsewhere as an LGA3647 part, that is wrong: LGA3647 is the Skylake and Cascade Lake socket, while every source placing this processor number puts it on LGA 4189. Second-hand listings copy each other's errors. Full range: Intel server CPUs.
Transparent Pricing
2026 Reference Pricing by Configuration
The Xeon Platinum 8331C is an OEM and cloud-custom SKU, not a retail product. Intel publishes no recommended customer price for it, so there is no list price to quote against and we publish no figure at all - every quote is built from the tray stock we can actually confirm for your quantity. The same discipline applies to the specification: because Intel publishes no datasheet for this SKU, what you receive is checked against your order specification rather than against an Intel product page, and we confirm it with you before the order is final.
Tray / OEM Single Units
On Request
Individually tested OEM tray stock and decommissioned pulls. Custom SKUs move in batches rather than steady supply, so availability is confirmed against live stock before we quote.
Matched Pairs
On Request
Matched pairs for dual-socket FCLGA4189 builds, so a 2P system is not assembled from unrelated lots. Tell us your board and platform generation.
Volume Orders (10+ units)
On Request
Multi-unit and repeat orders are quoted against live inventory, with freight consolidated from our Hong Kong warehouse.
No price is published for this SKU: it is an OEM and cloud-custom part with no Intel list price, and we will not print an uncollected number. Send us quantity and target platform for a firm quote. Intel-documented alternative on the same socket: Xeon Platinum 8358P. Full range: Intel server CPUs.

Quality Process
What We Check Before a Xeon Platinum 8331C Ships
Model String and Stepping Verification
Heat-spreader marking is read under magnification and checked against the exact model string on your order, including the sSpec. Intel publishes no ARK page for this SKU, so verification is physical plus order-specification rather than a database lookup.
FCLGA4189 Pad Inspection
The land array is inspected under magnification for bent contacts, contamination or rework marks - the most common reason a decommissioned server CPU is rejected.
POST and Core Enumeration
Full 24-core / 48-thread POST on a reference FCLGA4189 board, with every core and every memory channel exercised so nothing is silently dead.
Thermal Behaviour Under Load
Load temperatures are logged against the 185W figure this part is listed at, so units with degraded heat-spreader contact are pulled before shipment.
Board and Firmware Compatibility
BIOS and microcode compatibility is confirmed against your board family when you tell us the platform in advance - on a custom SKU, the platform's supported-CPU list is the practical compatibility check.
Report in the Box
Every unit ships with its per-machine diagnostic report and warranty. Full process: inspection guide.
Frequently Asked Questions
How much does an Intel Xeon Platinum 8331C cost?
We quote it against live tray stock rather than publishing a price. This is an OEM and cloud-custom SKU: Intel publishes no recommended customer price for it, so there is no list price to reference, and printing a number would mean guessing. Send us quantity and target platform for a firm quote.
What is the difference between the Xeon Platinum 8331C and the Xeon Platinum 8358P?
They share the FCLGA4189 socket, and that is where the similarity in evidence ends. The 8358P is an Intel-documented product: Intel's own specification gives it 32 cores / 64 threads, a 2.6GHz base clock, 48MB L3, 240W and PCIe 4.0 across 64 lanes, with a published recommended customer price. The 8331C is a non-ARK custom part with 24 cores / 48 threads, a listed 2.5GHz base and 3.5GHz maximum turbo, 36MB L3 and 185W, all from the public Ice Lake Xeon list rather than from Intel, and with no published all-core turbo, PCIe lane count, launch date or price. In short: fewer cores, less cache and lower power on the 8331C, on thinner evidence. If your platform specifies the 8331C we supply and verify the 8331C; if you want a datasheet, buy the 8358P.
Why is there no all-core turbo, PCIe or launch date on this page?
Because the sources do not state them, and an unsourced number on a specification table is worse than a blank. Intel publishes no ARK page or datasheet for the 8331C, the public Xeon list that does record this part gives only the maximum turbo figure (its all-core column is blank), and no source we reached states a PCIe lane count or a launch quarter. Those are omitted and confirmed against the physical part and your build sheet at order time.
What condition are these CPUs in, and what warranty applies?
Units are graded OEM tray stock and decommissioned server pulls: model marking and sSpec verified against your order specification, FCLGA4189 pads inspected under magnification, full 24-core POST with all memory channels exercised, and thermal behaviour logged. Each CPU ships with its diagnostic report and a 1-year warranty.
Can you ship the Xeon Platinum 8331C worldwide from Hong Kong?
Yes. We ship worldwide from our Hong Kong warehouse with full export documentation, and express air freight typically arrives in 3 to 7 days to major markets. For volume or multi-SKU orders we consolidate freight with memory, storage and chassis to reduce the per-unit cost.
