Hello everyone

This is my first time building a PC with second-hand components, and I have no experience with used parts. Could you guys help me check if this second-hand AMD CPU is worth buying? The green coating on the edges is missing, but the pins look fine.

My current CPU is too old i5-6600k does not support win11 , so I want to buy a second-hand CPU with adequate performance that isn’t too expensive.It is local pickup around 180 Canadian dollar(125usd).

This processor appears to have had its cap removed sometime in the past, if I can trust my eyesight. It's unclear for what purpose and whether it would work as expected, if at all.

IHS removed:

1. LN2 OC

2. Deceptive practice

I would only buy a used part if there is buyer protection

a few of the pins look dark as well can't tell if its just the light or if they are burnt possible substrate damage
No to many questions for a old outdated cpu, unless its very cheap (sub 75 usd) I would not bother you can get better examples on ebay for 150 usd or better yet go with something like a 5600x which is easily had for under 100 usd you are still looking at replacing the motherboard and ram anyway so no sense buying that 3900x

I couldn't tell you what the chip at the top is from, but other than that, the pins look straight and fine to me.

That being said, I wouldn't be looking at a 3900X unless you do very highly threaded production work, and I'm going to guess you don't since you have a 6600K. Otherwise, you have better choices. The thing with the 3900X is, like all Ryzen 9s, it's multiple CCDs, but on top of that, each CCD was sort of "virtually" further split into CCXs before Zen 3 (Ryzen 5000 series), so the 3900X is a bit like a 3+3 and 3+3 CPU. This can cause latency penalties in anything that crosses those core counts. For highly threaded productivity where latency doesn't matter, it's a performant CPU, but for general use/gaming? I'd pass. I know of people who used it for general use/gaming and regretted it. The Ryzen 9 x900 tier has always been a niche option and the 3900X in particular was the worst of them due to the CCX split.

If you need an AM4 budget option in a pinch, I would consider the 3700X a better choice (it's a 4+4 single CCD, so it has the best chance of avoiding the CCX penalty and no CCD penalty), but ultimately I'd look for a used 5600, 5600X or 5700X instead as they also have no CCX penalty concerns and are more performant while still being cheap on the used market.

Local Pickup huh, he should have the seller meet him at a pc repair shop to verify the cpu posts and doesn't crash under idle or load, if the seller turns that down don't buy it and report them on Social media/advertising website and authorities.

On ebay I was purchasing what I thought was a 5800X for 362 in 2021, after I received it, it stated 5800, I took it to Microcenter to verify if it was an X or not and that it would Post and not crash.
I paid 40 for that test.

I requested money back after I gave undeniable proof it was a 5800 and not an X. He spilled the beans that it came out of a dell and offered $85 back, I turned it down for $100, he agreed and sent me 100 back and I warned him to not be deceptive, so I got the 5800 for $262 at the time. I also knocked his reputation down a few points for that bs.

why ? new 5600x/5700 cost under 130 US dollars, why would you pay the same for a used zen2 ?

That depends on how much you pay for it and what your expectations are. For me that usually means pay a lower price for something I'm fairly certain I can fix (no guarantee though!).

There are ways to bypass W11 system requirements for your existing system they are all over youtube.

I've gotten Windows 11 update avaliable notifications on systems that weren't originally supporting Windows 11 (Ryzen 5600 with TPM disabled), the requirements has changed.

That being said, I wouldn't be looking at a 3900X unless you do very highly threaded production work, and I'm going to guess you don't since you have a 6600K. Otherwise, you have better choices. The thing with the 3900X is, like all Ryzen 9s, it's multiple CCDs, but on top of that, each CCD was sort of "virtually" further split into CCXs before Zen 3 (Ryzen 5000 series), so the 3900X is a bit like a 3+3 and 3+3 CPU. This can cause latency penalties in anything that crosses those core counts. For highly threaded productivity where latency doesn't matter, it's a performant CPU, but for general use/gaming? I'd pass. I know of people who used it for general use/gaming and regretted it. The Ryzen 9 x900 tier has always been a niche option and the 3900X in particular was the worst of them due to the CCX split.

Basically this. A 3600, 5600 or even a 2600 would be more sensible for general use and gaming.

Note that rather deceptively, the 5700 non X is not Vermeer, but Cezanne with iGPU disabled... and as a result much worse than the 5700X - just avoid this model altogether

Ohh, didn't know that.

I don't see anything wrong but you never know sometimes when buying used.

If ebay is your thing there is a north american listing for a complete combo for only $250 - Ryzen 9 3900x CPU, MSI Tomahawk Max Motherboard, 16GB Corsair Vengeance DDR4. Seems like a pretty good deal if your comfortable with the risk. Not sure if import fees might apply.

On the other side of the coin for $1 more you could get a new Zen3 5700 8-core on NewEgg.
Less cores but newer Zen3 CPU, and no guessing if it's damaged, and no CCX/CCD issues for gaming.
Based on your current CPU AMD 5500 might also be a valid less expensive choice. Presumably you will still need other parts too.
5600x/5700x would be better choices if you can find them in your price range.

Ouch. I forgot about that. (edit) ...but it's still Zen3

The ryzen 3900x is not worth it anymore. Too old and too outdated.
Literally this. I run a 3600 all day at 4GHz and it is far more than enough for my needs, which is next to nothing really.
If there is something I'm doing that MUST BE ON, I hand it off to my Athlon 2650e and let it go brrrrr.
If I'm doing something medium to highly threaded, I hand it off to my FX-8370 and it usually does a fair job.
When I have anything else highly threaded that needs to qualify or needs done RIGHT NOW, R5 3600 for the win.
The 3900X is effectively double what I have here. It's a 12c/24t part and it's fast af boi.
The 5900X is a newer generation part with optimizations and performance over the 3900X, often with a +$130 premium.

They're GREAT chips. Just make sure they're the right ones for you.

with halved cache
But much less power Consumption. The Cezanne-CPUs are in the Desktop-Load and in Idle the CPUs with the lowest Power/Watt-Ratio at this Time. Thats why i like them. But there is one another Disadvantage: PCIe 3.0 not 4.0 if you need this. This would effect a NVMe Drive more than a Graphics Card with 16 Lanes but thats one another Thing. The Cezanne CPUs got some Benefits and some big Cons.

180 CAD is a lot of money for a used Zen 2 processor. That's about the current market price for a brand new i5 13400 and Ryzen 5600.
It's a good point to bring up if OP has to change socket anyway to look at offerings from both camps to find the price/performance match that fit's in the OP's budget.
