RAM upgrade

What fits

The board has 2 desktop DIMM slots (288-pin) and takes DDR4, non-ECC, unbuffered memory at 1.2 V. Standard desktop DIMMs fit — not laptop SO-DIMMs. Nothing is soldered, so both sticks are removable.

The limits

HP and Kingston validate 16 GB per slot and 32 GB in total (2 x 16 GB). Speed is set by your processor rather than the board: with an i5-10400/F the memory runs at up to DDR4-2666, while an i7 or i9 gets DDR4-2933. Faster 3200 MT/s modules will simply clock down to match — there is no XMP and no memory overclocking here, so paying extra for speed ratings above 2933 gains you nothing.

If you want 64 GB, be aware that this is not validated. Owner reports show 2 x 32 GB sticks POSTing and running, but HP's documents cap the machine at 32 GB and it's not officially supported. ECC and registered memory will not work.

What to watch out for

With only two slots, there's no point adding a single stick alongside your existing one — buy a matched 2 x 16 GB kit and replace what's there, so the machine runs in dual channel. Also note that HP does not cover owner-installed memory under its support.

Buying tips

Buy a matched pair of DDR4-2666 or DDR4-2933 desktop DIMMs (non-ECC, unbuffered, 1.2 V). 3200 MT/s kits are fine and will clock down, but don't pay a premium for them.

Consejos de compra

• Matched 2 x 16 GB DDR4 kit for the validated 32 GB maximum
• DDR4-2666 or 2933 is all you need — faster kits clock down and there's no XMP
• Non-ECC, unbuffered, 1.2 V desktop DIMMs only

Storage upgrade (M.2 SSD and SATA drives)

What fits

There are two storage routes: one M.2 NVMe slot and 3.5-inch SATA drive bays.

The M.2 slot is a Key-M socket that takes 2242, 2260 or 2280-length NVMe SSDs at PCIe 3.0 x4. Most configurations ship with a 256 or 512 GB NVMe drive already in it, so check whether you're replacing or adding before you order. The second M.2 socket on the board is a small Key-A slot for the Wi-Fi/Bluetooth card — it does not take storage.

For bulk storage, HP's Japanese chassis spec documents 2 x 3.5-inch SATA bays (SATA 6 Gb/s) with one free, while HP's US pages list only a single SATA hard drive. Count on at least one guaranteed free bay; a second may require removing the existing hard drive. Drives sit in the fixed caddy and take 9.5 mm-class units.

The limits

The M.2 slot is PCIe 3.0 only. Gen4 and Gen5 NVMe drives are backward compatible and will work, but they run at Gen3 speed — there's no point paying for top-end models. Only NVMe is documented on this slot, so SATA M.2 drives are not a safe bet. HP publishes no drive capacity limit, and owners use 2 TB NVMe drives and large SATA drives in practice.

There is no dedicated 2.5-inch bay. A 2.5-inch SATA SSD needs the 3.5-inch bracket or a third-party adapter in the usually empty optical bay on most configurations.

What to watch out for

The front-panel card reader is read-only and isn't a storage expansion option. And if you're adding rather than replacing, check free SATA power connectors — the power supply has a short, compact cable set.

Buying tips

A mainstream PCIe 3.0 NVMe SSD in 2280 size is the sensible buy. If you add a SATA drive, get a 3.5-inch hard drive that fits the caddy directly, or budget for a bracket if you want a 2.5-inch SSD.

Consejos de compra

• M.2 2280 NVMe (PCIe 3.0 x4) — Gen3 drives give you everything the slot can do
• Skip Gen4/Gen5 premium models; they run at Gen3 speed here
• For a 2.5-inch SATA SSD, allow for a 3.5-inch bracket or optical-bay adapter

CPU upgrade

What fits

The processor is socketed (LGA1200) and upgradeable. The BIOS supports 10th-gen Comet Lake-S Celeron, Pentium and Core i3/i5/i7/i9 parts up to 65 W — locked models only. Moving from a stock i5-10400/F to an i7-10700/F or i9 is the realistic upgrade path.

The limits

Stay at 65 W. The stock cooler uses HP-specific mounting, and the machine ships with a ~310 W compact HP power supply (with a single PCIe lead), so the platform is designed around 65 W processors. 11th-gen (Rocket Lake) chips are not supported by HP's BIOS even though the socket is the same, and there is no support for unlocked 'K' processors or overclocking.

What to watch out for

Don't assume every LGA1200 CPU works just because it physically fits — only the 10th-gen 65 W parts above are supported. If you swap in an aftermarket cooler, verify the mounting and clearance first, since the stock unit uses HP's own hardware.

Buying tips

Look for a 65 W 10th-gen Intel Core i5, i7 or i9, unlocked only in the sense of upgrading the socketed chip — not overclockable. Used or pulled chips are common and sensible here.

Consejos de compra

• 10th-gen Intel Core i5/i7/i9, 65 W, locked models only
• Not 11th-gen — HP's BIOS does not support Rocket Lake
• Keep the CPU at 65 W; the cooler and ~310 W power supply set that ceiling

Before you buy: the power supply

The single biggest limit on upgrades is the power supply: a ~310 W compact HP unit with a 4-pin CPU lead and only one PCIe (6+2-pin) connector. It's fine for the components above, but a bigger graphics card will likely need a power supply swap. Note that the HP unit is a non-standard compact length with a short cable set, so check connector and case compatibility before buying a replacement.

Cómo ampliar

Antes de empezar

• Back up your data before touching any hardware.
• Shut down the machine, switch it off at the back if there's a switch, and unplug the power cable and everything else.
• Ground yourself to avoid static damage — touch the metal chassis or use an anti-static wrist strap.
• Open the case following the owner's manual for your exact model; fastener locations and panel removal vary.
• Install the part, making sure it is seated fully and secured.
• Close the case, reconnect the power and cables, and switch on.
• Check that the BIOS/firmware reports the new memory, drive or processor at the expected capacity and speed, and confirm your operating system sees it too.

Pasos

1. RAM
   Power off, unplug and ground yourself. Open the case (see the owner's manual). Release the retaining clips on the DIMM slots, remove any modules you're replacing, and press the matched pair firmly into the slots until the clips click. Close up and check the BIOS reports the full capacity.
2. Storage
   Power off, unplug and ground yourself. Open the case. For the M.2 SSD, locate the Key-M slot (not the small Key-A Wi-Fi slot), slide the drive in at a shallow angle and secure it with its screw. For a SATA drive, mount it in the free 3.5-inch bay/caddy and connect the SATA data and power cables. Close up and confirm the drives appear in the BIOS. If you cloned your system onto a new drive, check the boot order before the first start.
3. CPU
   Power off, unplug and ground yourself. Open the case and remove the cooler according to the owner's manual. Lift the socket lever, swap the 10th-gen 65 W processor without touching the pins or contacts, reseat it, close the lever and refit the cooler (HP-specific mounting). Check the BIOS reports the new processor model correctly.

Es bueno saberlo

• Owner-installed memory is outside HP's support coverage.
• HP's US and Japanese documents differ on the number of SATA drive bays — see the storage section.

Preguntas frecuentes

How much RAM can the HP Pavilion Gaming Desktop TG01-1000 take?

HP and Kingston validate 32 GB — 2 x 16 GB DDR4 desktop DIMMs across the two slots. Larger sticks are not validated; see the RAM section for the 64 GB question below.

Does the TG01-1000 support 64 GB of RAM?

Not officially. HP documents a 32 GB maximum, but owner reports show 2 x 32 GB modules POSTing and running. Treat it as unsupported and buy at your own risk.

Does it support XMP or DDR4-3200 memory?

There is no XMP or memory overclocking. DDR4-3200 modules work but clock down to 2666 (i5) or 2933 (i7/i9), which is the fastest the board runs.

What SSD does the TG01-1000 take?

An M.2 2280 (also 2242/2260) NVMe drive in the Key-M slot at PCIe 3.0 x4. There is also at least one free 3.5-inch SATA bay for a hard drive or — with a bracket — a 2.5-inch SSD. The second M.2 socket is for the Wi-Fi card.

Can I use a PCIe 4.0 NVMe SSD?

Yes, it will work, but the slot is PCIe 3.0 x4 so the drive runs at Gen3 speed. There's no benefit to a Gen4 or Gen5 model here.

Which CPUs can I upgrade to?

Only 10th-gen Intel Comet Lake-S Celeron/Pentium/Core i3/i5/i7/i9 65 W locked processors. 11th-gen Rocket Lake is not supported by the BIOS, and 'K' unlocked chips and overclocking are not supported.
