Is my 2500k dead? If so is ryzen the most cost effective upgrade option?

Hi everyone,

I've had my 2500k for over 5 years now and it's always been set to a mild overclock of about 3.9Ghz.

I restarted the computer about two weeks ago and before windows loaded to the blue title screen I got the machine check error.

Now I've spent the last 8 or so evenings stripping everything back so I have the motherboard, PSU, CPU , ram , a tested blank HDD and a cd drive and I cannot get the thing back on its feet. I've bought a cheap working 1155 CPU of eBay to test if it's the motherboard but if it is the motherboard or the CPU then I'm very tempted to just upgrade the who rig to a newer platform. Only trouble is I've not much money to play with.

I've got a nitro 480 8GB which I'd like to keep but realistically, if I sold all the other components, CPU, motherboard and 16GB DDR3 should I upgrade to ryzen? I was thinking if I got a B350 motherboard and say the 1300x and a few sticks of Ram, would I get a similar performance to the 2500k? Plus I could always upgrade the AM4 CPU in years to come.

Your thoughts please?

  1. That sounds like it could either be a motherboard or a PSU issue, CPUs don't usually die like that, specially with a 3.9Ghz overclock on a chip that is known to have run 4.5Ghz on the daily for many users for years that are still alive.

    As for the upgrade, if you're going with Ryzen, I'd recommend picking up at least a R5 1400 non X with a B350 motherboard and maybe clock it a little higher, as the SMT will help with more multicore friendly situations compared to the 1300x's only 4 threads.

    Have you tried another power supply perhaps?
  2. AMD Ryzen 1300x is not just equal but much faster than i5 2500k. I would even go so far as to say that you can save up more money by buying a 1200. It can be easily overclocked on the stock cooler to a slightly higher clock than that of 1300x and possibly even more. THese Ryzen coolers are awesome. All this if the ambient temps are lower than 22 degree celsius. See the following review:

    https://www.anandtech.com/show/11658/the-amd-ryzen-3-1300x-ryzen-3-1200-cpu-review/11

    You will notice that a 1200 on stock beats or gets very close to even an i5 Kaby Lake. That too on CPU intensive games such as Civ 6 and AOTS. Please read the whole article to make an informed choice and maybe more articles from reputed sites such as Toms, hardware canucks, overclock 3d etc.

    And, your line of thinking is spot on. You can always upgrade to a new AM4 CPU down the line as the motherboard will likely support any new CPU released till 2020. AMD has kept it real simple this time!

    I haven't tried a PSU yet. I didn't think that could cause the issue at all?

    I'll give it a try tonight and get back to you.

    Thanks
  4. Ok so the PSU change didn't help, so that leaves motherboard or CPU. I've got a cheap 1155 dual core ordered of eBay so I'll give that a blast when it comes. Trouble is there isn't many cheap 1155 motherboards, especially ones that allow overclocking.

    I'm pretty sure its the motherboard at this point, but if its a CPU, maybe you could grab a 2600K and be on your way for a few more years.

    That's my fear, cause its not like they make them new anymore and it's 5 year old technology. Ryzen here I come perhaps.
  7. Well you can always buy a used i7 2600K, you can find them for 100$ I believe, which beats having to buy new CPU + MOBO + RAM, unless you're itching to upgrade.
  8. Definitely a tricky position to be in. If you don't have spare parts, diagnostics can be costly and given the age of the board/CPU, upgrading rather than trying to diagnose which part is failing.

    One thing I would try to avoid is buying up parts on hunches, gambling on if that is the part that will fix the issue. Sure you could get that CPU for a hundred bucks or something, but if it doesn't work then what? The money invested fixing the issue yourself could go towards a new system. Also I've been a tech about a year now and have yet to see a failed CPU that wasn't very highly overclocked.

    If I was in a similar position, I would:

    a). Upgrade to a cost effective newer platform like Ryzen 3 or Ryzen 5 if possible and bring over the graphics card.

    b). Find a shop that does free estimates/diagnostic and get them to figure out which part isn't working. Even 1-2 hours of diagnostic labour would be better than buying just guessing. If they are a decent shop they will have a sandy bridge board somewhere they can test your parts on. I know it sounds weird telling someone to go to a shop, but if you want to stay on sandy bridge then that's my recommendation.
  9. Well I bought a cheap CPU of eBay. A little G630 2.7Ghz. I've loaded windows ( not Registered) and all the drivers and it's working fine.

    Soon as a swap back to the 2500k it's machine check error time.

    The king is dead. Long live the king.
