Memory (RAM)

The Precision 7510 has four 262-pin DDR4 SO-DIMM slots and no soldered memory, so every module is replaceable. The maximum is 64 GB, which means 4 x 16 GB. Dell does not support 32 GB SO-DIMMs, so the per-slot ceiling is 16 GB; if you see a listing claiming 128 GB for this machine, it is wrong. Desktop DIMMs will not fit — you need laptop SO-DIMMs.

On speed: the spec sheet lists a DDR4-2667 MT/s SuperSpeed option, but that was an order-time configuration capped at 32 GB. The Skylake memory controller is officially DDR4-2133, so third-party modules rated at 2667 MT/s or higher will run at 2133 MT/s anyway. Don't pay a premium for fast-rated DDR4 here; ordinary 2133 MT/s modules are the sensible buy.

Populate either two or four modules, never three. Dell warns that three modules cause performance problems, and one revision of the manual also cautions against running a single module. Buy matched pairs and fill the slots in twos.

ECC is the one real fork in the road. ECC memory only functions with a Xeon E3-1500M v5 processor; Core i5 and i7 machines run non-ECC only. Either way the machine takes standard unbuffered SO-DIMMs — registered (RDIMM) and LRDIMM modules are not supported. On total capacity, Dell's spec sheet and owner's manual state 64 GB max with ECC, while some independent coverage describes 32 GB of ECC as the ceiling; treat the 4 x 16 GB figure as the documented maximum and verify with Dell if ECC at 64 GB matters to you.

Buying tips

• Buy 2 or 4 modules (matched pairs), never 3
• 4 x 16 GB DDR4 SO-DIMM for the 64 GB maximum; 32 GB modules are not supported
• Save your money on speed ratings — 2133 MT/s is as fast as it will run
• Only buy ECC modules if the laptop has a Xeon E3-1500M v5 CPU

Storage (SSD / HDD)

There are two storage bays: one M.2 2280 Key-M slot (22 x 80 mm) and one 2.5-inch SATA bay. That is the real-world layout — Dell's spec sheet wording is ambiguous and can be read as two M.2-capable bays, but the owner's manual and independent reviews confirm one M.2 plus one 2.5-inch bay, for a maximum of two drives. RAID 0 and RAID 1 are possible through Intel Rapid Storage Technology.

The M.2 slot accepts either a PCIe x4 Gen3 NVMe SSD or a SATA M.2 SSD. Dell documents sizes up to 1 TB, and larger modern drives are known to work in practice. Note that this is a 2280-only slot: shorter 2230/2242/2260 drives need an adapter to fit. The slot is PCIe Gen3, so a Gen4 drive will work but run at Gen3 speeds.

The 2.5-inch bay takes SATA drives 5, 7 or 9.5 mm thick; 15 mm drives will not fit. Dell's documented maximum is 2 TB for a hard drive, and larger modern 2.5-inch SATA SSDs work fine — those official figures just reflect the parts available in 2016. If your machine came with only an M.2 drive, Dell supplied an empty bracket for the 2.5-inch bay.

One important trap with third-party NVMe drives: the system ships with SATA Operation set to RAID (Intel RST) mode. To use a vendor's NVMe driver and get full performance, you switch SATA Operation to AHCI first and boot Windows in Safe Mode once before rebooting — switching directly causes a blue screen. Doing this also forfeits RAID, so decide before you start. The SD card reader is present and handy for backups, but it is not an upgrade slot. There is no Thunderbolt, ExpressCard or WWAN slot, so plan storage around the two internal bays.

Buying tips

• M.2: any 2280 NVMe (PCIe x4 Gen3) or SATA SSD — shorter lengths need an adapter
• 2.5-inch: SATA SSD or HDD up to 9.5 mm thick; 7 mm is the safe modern standard
• Two drives max — one M.2 plus one 2.5-inch
• Before installing a third-party NVMe drive, plan the AHCI switch and Safe Mode boot if you want the vendor's driver

Processor (CPU)

Yes, the CPU is replaceable. It sits in a zero-insertion-force mobile rPGA socket rather than being soldered, so upgrades are possible — a rarity in laptops. Dell's documents don't name the socket in standard desktop terms; this is the mobile PGA946 / Socket G3 family, not the desktop LGA1151 socket, so desktop chips will not fit. The owner's manual covers processor removal and replacement.

The limits are strict. Only 6th-generation Skylake-H processors are supported: Core i5-6300HQ, Core i7-6700HQ / 6820HQ / 6920HQ, and Xeon E3-1505M / 1535M / 1545M / 1575M v5. Every factory option is rated 45 W, and that is the thermal ceiling — there is no faster 55 W part to move to. Kaby Lake (7th-gen) and later processors are not supported by the chipset and BIOS, so ignore any listing suggesting a 7th-gen swap.

Realistically, CPU upgrades here are low value: the supported range is narrow, and the most interesting move is from Core to Xeon, which is what enables ECC memory support. If that matters to you, pair a Xeon E3-1500M v5 with ECC SO-DIMMs. Otherwise, money is usually better spent on an SSD or more RAM. Whatever you do, check that the BIOS and firmware recognise the new part after installation, and consult the owner's manual for the exact disassembly and heatsink procedure.

Buying tips

• Only 45 W Skylake-H parts fit; 7th-gen and later will not work
• Move from Core to Xeon E3-1500M v5 only if you want ECC memory support
• Check current prices against the effort — the fastest supported parts are the sensible targets
• Have fresh thermal compound ready for the heatsink

How to upgrade

Before you start

• Back up your data before opening the case.
• Shut the laptop down completely and unplug the AC adapter.
• Ground yourself (or use an anti-static strap) before touching internal components.
• Open the case following the owner's manual for the exact screw locations and disassembly order.
• Install the new part, close the case, and power on.
• Check in the BIOS / system setup (and your operating system) that the new component is recognised at the expected size or speed.

Steps

1. Before you start
   Back up your data, shut down fully, unplug the AC adapter, and ground yourself to avoid static damage.
2. Open the case
   Open the case as described in the owner's manual. Keep track of screws and release latches; the manual is the authority for the exact procedure for your unit.
3. Install the part
   Fit the memory modules in matched pairs (2 or 4), seat the M.2 2280 drive in its slot, mount a 2.5-inch drive in its bracket, or swap the processor in its ZIF socket as applicable.
4. Close up and verify
   Close the case, reconnect power, and boot into BIOS / system setup to confirm the machine sees the new component at the right capacity or speed. If you installed a third-party NVMe drive and want its vendor driver, handle the SATA Operation (AHCI) change and Safe Mode boot at this stage.

Good to know

• Dell's spec sheet wording on storage bays is ambiguous; the owner's manual and independent reviews confirm one M.2 2280 slot plus one 2.5-inch bay.
• Dell's documents and some independent reviews disagree on the maximum ECC memory capacity.
• Socket naming is not consistent across documents; this is a mobile PGA946 / Socket G3-class socket, not desktop LGA1151.

Frequently asked questions

How much RAM can the Dell Precision 7510 take?

Up to 64 GB, using 4 x 16 GB DDR4 SO-DIMMs. 32 GB modules are not supported, so the per-slot maximum is 16 GB.

Does the Precision 7510 support ECC memory?

Only with a Xeon E3-1500M v5 processor. Core i5 and i7 machines run non-ECC memory only. Note that Dell's documents and some independent reviews disagree on the maximum ECC capacity, so check with Dell if you need a guaranteed 64 GB ECC configuration.

Does the Precision 7510 support NVMe SSDs?

Yes. The M.2 2280 Key-M slot supports PCIe x4 Gen3 NVMe or SATA SSDs. The machine ships in RAID (Intel RST) mode; switching to AHCI is needed for some third-party NVMe drivers, and it gives up RAID.

Can you upgrade the CPU in the Precision 7510?

Yes — the processor is socketed, not soldered. Only 6th-generation Skylake-H parts are supported (Core i5-6300HQ, i7-6700HQ/6820HQ/6920HQ and Xeon E3-1505M/1535M/1545M/1575M v5), all at 45 W. 7th-generation and later CPUs are not supported.

How many drives fit in the Precision 7510?

Two: one M.2 2280 SSD (NVMe or SATA) plus one 2.5-inch SATA drive up to 9.5 mm thick. RAID 0 and RAID 1 are possible across the pair.

Does the Precision 7510 have Thunderbolt?

No. There is no Thunderbolt, ExpressCard or WWAN slot. Expansion is limited to USB, video outputs, Ethernet and the SD card reader, so plan storage around the two internal bays.
