If you work in IT, you know the “e-waste picking” crowd. I’m one of them — used enterprise hardware is cheap and performs well, and nothing epitomizes it like the Xeon E3/E5 lines: multi-core, multi-thread CPUs for a few dozen yuan, sometimes just a few. But by the law of board-and-CPU pricing, the cheaper the CPU, the pricier the motherboard. So I put together a rough compatibility table of Intel chipset generations, the CPU generations they take, and the DDR memory generations they support, for my future junk-picking reference. If anything’s wrong, contact me and I’ll correct or expand it.
Intel mainstream desktop chipsets
The common, mainstream desktop boards first:
| # | Series | Chipsets | Socket | Core CPUs | Xeon CPUs | Memory | Notes |
|---|---|---|---|---|---|---|---|
| 1 | 8 series | H81, B85, H87, Z87 | LGA 1150 | 4th gen (Haswell) | E3 v3 | DDR3 | Some boards support E3-1200 v3 (LGA1150, iGPU disabled, no ECC) |
| 2 | 9 series | H97, Z97 | LGA 1150 | 4th/5th gen (Haswell/Broadwell) | E3 v3/v4 | DDR3 | Supports E3-1200 v3/v4 (BIOS update needed; Z97 allows some OC) |
| 3 | 100 series | B150, H170, Z170 | LGA 1151 | 6th gen (Skylake) | E3 v5 | DDR4 / DDR3L | Only C232/C236 server chipsets support E3 v5/v6 (desktop boards don’t) |
| 4 | 200 series | B250, H270, Z270 | LGA 1151 | 7th gen (Kaby Lake) | Not supported | DDR4 | E3 v6 requires C236 server chipset |
| 5 | 300 series | B360, H370, Z370/Z390 | LGA 1151 | 8th/9th gen (Coffee Lake) | Not supported | DDR4 | |
| 6 | 400 series | B460, H470, Z490 | LGA 1200 | 10th gen (Comet Lake) | Not supported | DDR4 | |
| 7 | 500 series | B560, H570, Z590 | LGA 1200 | 10th/11th gen (Rocket Lake) | Not supported | DDR4 | |
| 8 | 600 series | B660, H670, Z690 | LGA 1700 | 12th/13th gen (Alder/Raptor Lake) | Not supported | DDR4 / DDR5 | 14th gen support may require a BIOS update |
| 9 | 700 series | B760, Z790 | LGA 1700 | 13th/14th gen (Raptor Lake Refresh) | Not supported | DDR4 / DDR5 |
Xeon E3/E5 support
For e-waste pickers, Xeon E3/E5 support is the big question — but I can’t be 100% sure either. Many boards need a BIOS update to support Xeons, or don’t support them at all, because consumer boards were never designed for the Xeon line. Treat this as reference only.
Another point: most Xeons have no integrated GPU. The few models that do may require disabling the iGPU and using a discrete card. Based on reader contributions, here are the Xeons with iGPUs:
- Xeon E3 series: E3-12x5 — most E3 models ending in “5” have an integrated GPU (E3-1245, E3-1275, etc.), those ending in “0” don’t. There are exceptions: E3-1230 v6 and E3-1270 v6 also have iGPUs.
- Xeon E5 series: most have no iGPU; the few that do include E5-2403 v2 and E5-2407 v2.
The E3 line is Xeon’s single-socket line and E5 is the multi-socket line, so on consumer boards, you’re basically limited to Xeon E3.
E3 series (single-socket)
- E3-1200 v3/v4: compatible with 8/9 series boards (LGA1150), requires consumer chipsets (H87/Z97); no ECC memory support.
- E3-1200 v5/v6: server chipsets only (C232/C236), needs dedicated boards (e.g. ASRock E3C232D4U).
E5 series (multi-socket)
- E5-1600/2600 v1/v2: requires X79 chipset (LGA2011), quad-channel DDR3.
- E5-1600/2600 v3/v4: requires X99 chipset (LGA2011-3), quad-channel DDR4.
- E5-2600 v3/v4: some models support dual/quad-socket (requires server chipsets like C612).
Wrap-up
If you’re picking Xeon e-waste with consumer boards, your only option is Xeon E3. 8/9 series boards support E3 v3/v4 with limitations (no ECC, BIOS tweaks needed). 100 series boards may support E3 v5, but you’ll need to flash the BIOS and confirm with the seller.
Xeon E5 is walled off from consumer boards — it needs dedicated platforms (X79/X99/C612) and is incompatible with consumer chipsets entirely.
