Overclocking when I don't want to.

Hmm, not looking good there for the CPU!

Did you do a full CMOS reset/clear when you swapped the CPUs out?

Edit: noticed that my PCs have usually defaulted to SST = off / OS-control instead of hardware control (for speed shift). You may want to try that, though realistically I can't see why it would make a difference.
I did do the swap out. Not straight away but when I swapped it out I reset most settings anyway as the old cpu was overclocked.

I'll have a look at the SST but agree it can't make that much difference.
 
I'm starting to feel like I should say hang it all, grab my credit card, hope my family forgives me and buy this:

My basket at OcUK:

What is it they say, better to ask for forgiveness than permission?? lol

Also, you want this ram, the stuff you have is XMP for Intel systems.

Same ram, EXPO and much cheaper

Would be a great gaming base ofc, but FYI: you don't have to spend anywhere near so much to get a decent upgrade.

Here's some numbers from PassMark, the first number is single, the second is multl.

i7-7700K: 2715, 9643
i5-12400: 3514, 19329
i5-12600K: 3936, 27672
Ryzen 7600: 3912, 27096
Ryzen 9600X: 4583, 30093

A 12400F (same as 12400 without graphics) is around £100 and you can get a H610 motherboard to run it for ~£60 (or £80ish with wifi), then try your existing RAM unless you find it is broken (32GB is less than £50).

Thank you yeah, but I tend to prefer to buy big and less often lol and I've been green for an x3d since I learned they existed. I also have 3 other pcs to upgrade, the i5-6600k is in use and even worse an i5-4340. (I just upgraded the ryzen 9 1800x to ryzen 5 5600x)

I was thinking I'd upgrade the other two to ryzen 5 5600x and then this one to a big beauty... but maybe I should be sensible man like you suggest. :) Also if I go to am5 I have a board that may have a long life for upgrades to come?
 
It does not matter, takes longer to crash on small fft though. :( I should work out how to do a linux or freedos bootable that can run p95 really
Ah, if it crashes on both then hard to narrow down.
Could be CPU, board or ram issue if this is the case.

Personally, I see the AM5 X3D models as a halo product when they're priced at £450-£500, especially since the 7800X3D was close to £300 at one point.

Unless you have a really high-end card, like a 4080, or preferably a 4090/5090, in which case I can understand wanting to max that out.

I do like the 7700/9700X as options for a gaming PC, but even those are way overpriced in the UK compared to their prices elsewhere in the world. I'm hoping the 7400F will arrive at retail soon and offer a nice UK entry point into AM5.

Also if I go to am5 I have a board that may have a long life for upgrades to come?
I believe the replacement for zen 5 (9000) will be on AM5, but that is thought likely to be the last.
 
Wonder if the i7 7700k needs a bit more vcore?
It may, I just dont know how to add that, I'd be happy to try if you can tell me or point me to guide that says which voltages do what?

I kinda hoped there may be something like that, which could help her fly right, also tempted to just call it quits and put the i5 back. Just when it doesn't crash it is much faster thanks to the extra threads

Before I got the i7 it was run at 4800 for many years. The ebay seller isn't impressed that I claim it's got a fault and wont help me.

You could probably find an old video or guide made specifically for your motherboard, because it is a very high-end board.

Modern boards often use offsets to overclock or to undervolt, so that you can retain the CPUs power management behaviour rather than be forced to run the CPU at a fixed clock.

This is a guide with an older model:

You could try both, I guess, using a fixed CPU clock and voltage, or using an offset voltage. From what I can see in the manual of your motherboard, an offset is available for the CPU voltage.

I don't want to push the point, but a full clear cmos/reset and possibly applying the board defaults can be particularly important if you were previously overclocking (since these boards have loads of customisation options, including the VRM) and because you're changing from skylake to kaby lake, which is a new architecture with some changed features under the hood.

I have done a full cmos reset, pressed the button on the board. Thought I'd killed the pc until I realised that the thing was starting up using the integrated graphics!

I can do it again, but apart from trying XMP I've not done anything else with it since that cmos reset?

Thanks for the video I'll have a quick watch. I'm still not sure it will make it stable enough but worth a try I guess!
 
Also the board defaults is a set of profiles which I don't know what to pick from!
Ugh, the bios has more settings not in that video so I just don't really know what they do... I guess more reading is ahead.

I added an offset to add 0.02 volts and it still failed in prime95 but no blue screen.

Every failure in prime95 (which didn't blue screen where the worker ends with a rounding error) is always the same worker..

Interesting, what is the default volts for the CPU at full load? I'm guessing around 1.25?
 
yeah 1.25 I'm giving it 1.28 and it still failed. Except if I run prime95 for all the cores except that problem one, it just ran steady as rock for 3 hrs.

So I think there is definately a fault in core 1 when under load.

So I'm wondering if I can solve this by manually setting the core multipliers (instead of having them sync all cores) and scale core 1 way back.

I don't think I can outright disable a core can I?

Is that possible on this board? I thought that was a relatively recent feature. The manual does talk about something near the bottom, a Turbo utility, I wonder if you could with that?

You can, but I'm not sure if you can pick which one. Would be lucky if you picked 3 and it selected that one.
