Need Help Verifying HP-Branded NVIDIA RTX A4000 GPU Serial and Warranty Status

[qwang]

Hi HP Community,

I recently purchased an HP-branded NVIDIA RTX A4000 graphics card from a third-party seller (eBay), and I’m trying to verify whether this unit is brand new and covered under warranty.

Unfortunately, I couldn’t find any GPU-related category on HP's public support portal, and the standard serial number warranty check tool doesn’t recognize this component.

Here are the details of the GPU:

- Product: HP-branded NVIDIA RTX A4000
- Serial Number (S/N): CN24401536
- HP Assy No.: M12947-002
- HP Spare No.: N23438-001
- CT Number: PQZPRO1UIHBOGO

I would like to verify:
1. Whether this is a genuine HP GPU product
2. If it carries any HP warranty
3. Whether there's any previous activation or service history

The unit looks clean and came in anti-static packaging, but I want to confirm whether it’s actually unused.

Any guidance from HP staff or the community on how to check this — or which support channel handles OEM/workstation GPU components — would be greatly appreciated.

Thank you!

Normally we get FULL one year warranty (Australian regulations).

@qwang,

Welcome to our HP Community forum!

It is not that simple.

You're right to want to verify the status of your recently purchased HP-branded Nvidia RTX A4000 graphics card, especially when it comes from a third-party seller like eBay. Here's what I can tell you based on your provided details:

Product: HP-branded NVIDIA RTX A4000
Serial Number (S/N): CN********
HP Assy No.: M12947-002
HP Spare No.: N23438-001
CT Number: PQZPRO1UIHBOGO

1. Is this a genuine HP product?

Yes: the part numbers you've listed are known HP OEM identifiers:

• M12947-002 = HP Assembly number for the RTX A4000.

• N23438-001 = HP Spare number: HP PartSurfer.

• Serial number prefix CN2 indicates it was likely manufactured in China.

• The CT Number format is consistent with HP's internal component labeling.

These HP RTX A4000 cards are typically installed in high-end HP Z-series workstations (like the Z4/Z6 G4 & G5). They often include HP-customized VBIOS or thermals.

Conclusion: It’s most likely a genuine HP OEM GPU.

2. Does it have an HP warranty?

This is where it gets tricky.

HP generally does not offer direct warranty coverage on standalone parts sold outside of HP-authorized systems. Graphics cards like this are:

• Typically covered only as part of the system warranty they originally shipped with.

• Not eligible for HP warranty unless installed by HP or a certified HP reseller.

• Not listed in HP’s public warranty checker tool, which is why your serial number returns no result.

What you can do:

• Contact HP Workstation Support and request a warranty status lookup using the full serial and CT numbers. In the US, call 1 - 8 0 0 - 3 3 4 - 5 1 4 4 (HP Commercial Support)

• Or start a chat via HP Commercial Workstations support page.

• Without a proof of purchase from HP or an authorized reseller, however, it's unlikely that HP will honor a warranty.

---

3. Is there a way to check if it’s used or previously activated?

Unfortunately, HP does not provide public access to usage history or activation logs for GPU components.

As for local inspection:

Install the card and run freeware diagnostic tools such as:

• GPU-Z (https://www.techpowerup.com/gpuz/) to verify:

  • Device ID

  • BIOS version

  • Clock speeds

  • Memory size & type

❗Note: Whilst GPU-Z is great for real-time monitoring, it cannot show total power-on hours. Unlike hard drives or SSDs with S.M.A.R.T. logs, graphics cards do not track lifetime usage hours in firmware.

• You can also run stress tests such as: MSI Kombustor (my favorite), 3DMark, Unigine Heaven, or FurMark to evaluate thermal behavior and performance consistency.

---

Packaging & Physical Condition:

• HP typically ships OEM parts in plain brown boxes with a white label showing HP part numbers and barcodes.

• Anti-static bags are standard, but absence of official HP boxing or documentation makes warranty validation difficult.

---

Summary:

Checkpoint                                 Status

Genuine HP product?	✅Most likely
Covered by HP warranty?	❌Not directly; only if part of an HP system
Usage history available?	❌Not publicly; inspect locally only

---

If you're not experiencing any issues and the GPU performs well under load, it’s probably safe to assume the card is functional and serviceable -even if it’s technically "used" or out of warranty.

one thing that's been overlooked (but mentioned by (NonSequitur)  is that most HP quadro cards were part of a business or workstation/server system and as such in most of these cases the individual parts that make up the system do not have individual  warranties, the parts are covered under the "systems" warranty and this warranty is sometimes not transferable if the original buyer resells the system to someone else

some consumer HP systems are also warrantied the same way

however HP does sell this video card as a standalone product, so follow NonSequitur's advice and see if HP does cover this card but i suspect it's not under any HP warranty

the HP parts number(s) will tell HP if the card is a retail product with a seperate warranty or  if the part is covered under a compute system warranty

Thanks for the reply. 
I tried to find the chat link at HP Commercial Workstations support page, but couldn't find it.  Could you please point out where is it?

Thanks. 

On that page I cannot start a chat probably because I cannot input a valid SN?
