Buyer CPU Warranty Question

[Master PC]

I sold my Ryzen 9 5900X and ROG Crosshair VIII Hero X570 to a buyer. However, I lost the original AMD packaging and proof of purchase.

 

At least, he has the serial number and production number (the manufacture date) of the chip. If he runs into problems with the chip, will the SN and PN be enough for the vendors there to accept requests? I live in Taiwan BTW, so will the policies differ by country?

On the CPU front, AMD does not transfer warranties to second hand buyers, so that buyer is SOL if they have issues, unless they process it through you, which I find to be unlikely.

Many warranties don't transfer. And it is understandable since it will be unclear if one of the owners damaged the item. OC, lack of cooling, touching of contacts, bad voltages.... The buyer wouldn't know if you caused the issue, and you wouldn't know if the buyer did. With just one owner things are more under control. You know if you did something bad and consequently wouldn't file a warranty claim (unless you are less ethical ...)

 

And most warranties require proof of purchase. Just to track down how a broken product traveled through the sales channel (customer vs. bulk OEM sale) and to avoid providing warranty for stolen items.

Understood.

 

However, the buyer just got back to me again: The CPU manufacturer date is week 47 of 2021, and the buyer's friend told him the warranty would expire this year, as per AMD's Warranty time. But I thought the warranty begins upon purchase of the CPU which was in 2022, and warranty should end next year.

That's when it's supposed to begin, yes.

Is the CPU broken at all or why is the buyer so keen on warranty?

 

CPU failures are extremely rare if you exclude non-warranty damage like touching contacts.

 

And yes, most warranties start at date of purchase. This is another reason you need the receipt.

The buyer might just be trying to cover their bases, but at this point, it's too late unless the OP allows for returns, and this situation fits the requirements.

All that should be clarified at the time of sale. A non transferable warranty or lack of receipt would impact the price I'm willing to pay for used vs. new. I assume buyer and seller know each other since an anonymous sale wouldn't include all the after sale follow up.

 

Once installed and running, a CPU doesn't just fail before 3 years. It can fail due to lack of cooling, voltage, OC or general fooling around. None of that is warranty anyway. So all these concerns are unfounded 99.999999999999999999999% of the time.

My post implied that.

That's a bold claim. Conditions can absolutely be present that cause a CPU to fail prematurely, even if unlikely. No average person has any appropriate means to view and inspect the die.

Out of all hardware failures people report on forums, most will be MB, PSU, drives, etc. And the few CPU failures often are downstream effects of MB/PSU issues or the person going crazy with OC or similar. And installation errors. An actual manufacturing defect is very rare and should have manifested itself during the use with the first owner.

 

You can see that by many old CPU for sale for cheap due to a large number of still functioning CPU. But you see relatively few and expensive old MB. Obviously it started with same number of MB and CPU, but the MB died at some point while CPU lasted. 

 

Yes, there can be normal use failure after 2.75 years due to manufacturing defect. But that buyer should worry more about being struck by lightning.

This is basically the survivorship bias at play here. 

 

I'm not saying that other components are not more likely to fail than an IC, but to seriously suggest a buyer should not chase after a warranty because it's unlikely to be utilized is absurd. It's ultimately them deciding to take the risk, and if they're wrong, they're likely screwed as a result.

That is not what I said. IF there is transferrable warranty and the receipt, this of course that should be part of the purchase of a used item.

 

It appears used CPU have no transferrable warranty. So there will be a risk either way and that is why used hardware cost less than new. 

 

The buyer has no claim on warranty here, but also shouldn't loose sleep over that. Especially since most CPU failures are related to something else than manufacturing defect. I don't know the market value of that CPU, but between the RMA hassle, shipping and waiting for weeks, you are better off just buying a replacement if it actually fails.

Not really.  People, including me, buy tray CPUs all the time.  90 day warranty at best.

 

I have never and most likely will never care about a cpu warranty.

 

Survivorship,  sure.  Accurate, most likely .

 

I think his new buyer is being kind of petty.  Especially if the cpu is already working for him.

[-rascal-]

Factory/manufacturer warranty should go by purchased / invoice date - if you go through AMD / Intel.

 

When I went to RMA my i7-6800K through Intel, they asked for my NCIX (yeah) purchase invoice, and they went by that date.

Even though the warranty ended about a month prior, they still honored it. i7-6800K was EOL so Intel gave me a full MSRP refund - even though I bought on sale. I give Intel props for that. Knock on wood, having owned so many AMD and Intel CPUs, that was my very FIRST (hopefully only) CPU RMA experience.

Even if you think the risk is low(and CPUs do not fail all that often), it's still a risk. CPUs do actually fail, even if you or others don't hear about them. Having a warranty, if nothing else, gives peace of mind that in the event something goes wrong, you're covered, assuming it's within the terms of said warranty. People use CPUs in all kinds of different ways and different environments, so I'm not willing to just say "don't worry about the warranty". Is the risk low? Sure. But that's still risk management, and it's still a risk. And ultimately, when you purchase something secondhand, you need to understand the terms with both the seller, and the manufacturer. There's a good chance you're going to forgo any kind of warranty, and that's just how it is.

 

As a side note, at my workplace, we do RMA ICs, including SoCs because they failed, even in lighter environments that are less strenuous. 

 

Just because, the CPU is working now does not necessarily mean it'll work later, and it's very difficult to determine the root cause of the failure within the CPU.

I didn't know tray CPU have different warranty. They seem to have disappeared from regular retail channels. I loved them since one didn't pay for a (useless) stock cooler. 

 

Ultimately a warranty is an insurance. One has to decide if the added cost (and RMA hassle) is worth the risk. I personally wouldn't buy insurance for a $200 CPU. I would pay $40 less and take my chances. I mean, my car has $1,000 deductible, so insurance really only is for life standard threatening events. 

 

There is a bathtub curve for failure. 90 days warranty are plenty to know there isn't an initial manufacturing defect. 

 

Unfortunately most consumer items don't have the option to buy the lower warranty version.
