Where this part fits
- Dense virtualization
- Cloud-native platforms
- In-memory caching
32 cores, 48 MB of L3 and full DDR4-3200 support — the 6338 is the most common high-density part in retired Ice Lake fleets. Its 205 W envelope needs a proper heatsink and airflow, so check the chassis spec before ordering a pair.

What you get
- The processor itself, matched on sSpec SRKJ9
- ESD-safe packaging for transit

- 90-day warranty from delivery
Not included: heatsink, CPU carrier frame, and any licence. If you need the heatsink for your chassis, ask and we add it to the quote.
Why buyers source CPUs from Zhongxin Data
- Part-number level quoting. We quote by model plus sSpec, so what arrives matches what you specified.
- In-house re-flash and test line. Processors are checked on our own bench before they leave, not drop-shipped blind.
- Retail and wholesale on one account. Single units for a repair, volume tiers starting at 10 units for a rollout.
- One channel for the whole build. We also carry the servers, memory and RAID controllers these CPUs go into, so you can quote a complete node in one thread.
Other FCLGA4189 processors we hold: 4310 (12C, 2.1-3.3 GHz), 4314 (16C, 2.4-3.4 GHz), 4316 (20C, 2.3-3.4 GHz)
Browse all server processors - every page lists socket, core count and sSpec, so you can match a part to the chassis you already own.

FAQ
What sSpec is this processor?
This is sSpec SRKJ9. Every unit we quote is matched on sSpec, so you get the same stepping across the whole order rather than a mixed tray.
How many cores and threads does the 6338 have?
32 cores and 64 threads, running from a 2.0 GHz base clock up to 3.2 GHz maximum turbo, with 48 MB of L3 cache.
What socket does the 6338 need?
FCLGA4189. On that socket the part fits Dell PowerEdge R650 / R650xs / R750 / R750xs and similar boards.
What memory does the 6338 support?
DDR4-3200 across 8 channels. It will not run in a board wired for the other DDR generation, so confirm the platform before ordering.
What is the TDP and what cooling does it need?
205 W. Check the heatsink and airflow rating of the chassis before fitting a pair - the 205 W class needs the standard or high-performance heatsink option, not the low-power one.
Can I run two of these in one server?
Yes - 2S capable.
Can you supply matched pairs or larger volumes?
Yes. We quote single units, matched pairs from the same sSpec, and volume tiers that start at 10 units. Send the quantity you need and we come back with one price.
How do I get a price?
Pricing is quoted per order rather than published, so send the part number, sSpec and quantity on WhatsApp at +86 13068616914 and you get a written quote back.
What warranty comes with it?
90-day warranty from delivery.
Will this CPU work in the server I already have?
If the board takes a FCLGA4189 CPU and the BIOS supports the 3rd Gen Xeon Scalable (Ice Lake) family, yes. Tell us the server model and we confirm socket, heatsink and BIOS level before you order.
Does it support AVX-512 and Intel AMX?
Instruction set extensions: AVX-512, DL Boost (no AMX). If your software is built around AMX acceleration, pick a Sapphire Rapids, Emerald Rapids or Xeon 6 part rather than an Ice Lake one.
Can I mix different steppings in a dual-socket pair?
We do not recommend it. In a 2S board both sockets should carry the same model and the same sSpec, and we match pairs on sSpec by default when you order two.
