Frequently Asked Questions
The Intel Core i5-7600K Processor — 4 cores and 4 threads, 3.8 GHz base rising to 4.2 GHz with Turbo Boost, 6 MB Intel Smart Cache, 91 W processor base power, LGA1151. Supplied from stock with a 1-year warranty.
The unlocked Kaby Lake i5
The i5-7600K is the only unlocked 7th Generation i5 on the mainstream socket: four cores at 3.80 GHz with a 4.20 GHz Turbo and a 91 W envelope. It was the last unlocked quad-core i5 Intel shipped, and well-binned samples commonly held 4.8–5.0 GHz on good air cooling.
Out of the box it is already the fastest Kaby Lake i5; the unlocked multiplier is the reason to pick it over the 7600. Overclocking requires a Z170 or Z270 chipset board — H/B/Q series boards run it at stock clocks only.

Which systems take this processor
Anything on the FCLGA1151 socket with an Intel 200 or 100 series chipset: B250, H270, Q270, Z270, plus the 100 series boards H110, B150, H170, Q170 and Z170 after a BIOS update.
- Business desktops and SFF machines — Dell OptiPlex 3050 / 5050 / 7050, HP EliteDesk 800 G3 / ProDesk 600 G3, Lenovo ThinkCentre M710 / M910. This generation was the corporate volume platform of 2017, so replacement parts remain cheap and plentiful.
- Entry workstations — HP Z240 (late revision), Dell Precision T3620, Lenovo ThinkStation P320, where a 65 W quad-core covers office, light CAD and point-of-sale duty.
- Media and signage boxes — the integrated HD Graphics 630 added full HEVC 10-bit and VP9 hardware decode over the Skylake engine, which is why these parts are still common in 4K signage players.
One caveat when buying a board separately: 100 series boards may need a BIOS from 2017 before a 7th Generation part will POST. Tell us the board or the machine model when you enquire and we will confirm before you order.
How it compares across the i5 line
| Processor | Cores / Threads | Base / Turbo | Cache | Power | Socket |
|---|---|---|---|---|---|
| i5-7600 | 4 / 4 | 3.50 / 4.10 GHz | 6 MB | 65 W | LGA1151 |
| i5-7600K | 4 / 4 | 3.80 / 4.20 GHz | 6 MB | 91 W | LGA1151 |
| i5-7640X | 4 / 4 | 4.00 / 4.20 GHz | 6 MB | 112 W | LGA2066 |
| i5-8600K | 6 / 6 | 3.60 / 4.30 GHz | 9 MB | 95 W | LGA1151 |
The 7640X is the HEDT sibling on LGA2066 — same architecture, dual-channel memory on a different socket and cooler mount entirely. The 8600K is the six-core successor, and the reason the Kaby Lake K lost its appeal: same platform generation, two more real cores.
How each processor is tested before it ships
- Visual inspection of the integrated heat spreader, substrate and contact pads; the sSpec laser marking (SR32V on our i5-7600K stock) is verified against the Intel specification sheet.
- Burn-in on a matched diagnostic board with a pair of memory modules of the correct type for this platform.
- All populated memory channels and the primary PCIe lanes are validated, then the processor is identified in the BIOS and in the operating system.
- A sustained multi-threaded load test at full core count, with the clock and thermal readings recorded.
- Thermal paste cleaned off, final inspection, then packaging in an anti-static tray with foam — which is how it arrives to you.
Warranty and lead time
Every processor is covered by a 1-year warranty against defects in workmanship and function. If a part fails within the period we replace it or refund it, and we cover return shipping on a verified fault. Stock is held in our own warehouse and normally dispatches within three to seven working days; tracking is issued at dispatch.
Purchasing and volume enquiries
The minimum order quantity for this processor is 2 units. Price is quotation-based rather than listed, because CPU pricing moves with each incoming batch — send us the quantity you need and we will come back with a firm quote and the current lead time. Larger quantities ship from the same production batch so the sSpec and the stepping stay consistent across your order.
