Since my previous build some 10 years back

New Build, Pass judgement on this please.

Well, my trusty Striker 2 Extreme looks like it's finally bitten the dust, it went BSOD and even the most determined efforts to recover the system failed. At least I managed to recover my data and files. Anyway s, the new build. Please give me an answer on any potential issues that you may...

Which has been running overclocked at 4.5 Ghz almost all of this time, I decided that it was about time I built a new PC.
So as last time, I went with decent new components and will be documenting my build here (OK I started it last week, but 8 days between friends is nothing). :D
 
This week I'm getting it dialled in to run without any thermal throttling or power throttling.
So far I have managed to get Stock CPU setting running with just a peak power draw of 289W
So that's 2 cores at 6GHz 6 at 5.8 Ghz and all the 16 efficiency cores at 4.3Ghz and not going over 100C.

Still got some more work to do, but so far Prime95 on all 24 cores is the worst for power consumption with temperatures just hitting 100C.
Not going for all out performance with stupid power consumption rather a stable system that does not throttle.
Cinebench R23 Multi core 35297 points with CPU Package power of 261.5W so yes about 5000 down on some benchmark scores but this system will still be working (I hope) many years down the road.
Cinebench R23 Single core 2315 points with CPU Package power of 72.6W.

Still got work to do, but looking stable.
 
Nice tidy build that with a great spec.

And yes, they like to run hot on default BIOS settings that's for sure.

I reach 41k in R23 Multi core using stock settings on my KS, use AC/LL to bring those temps down.
I get a max temp of 81c in R23 with an average of 1.169v @ 250w (Custom Loop)

Still playing with the BIOS settings (When I have time), got it running stable, but resume from Standby seems to be broken, so still got to figure this out.
Got 2 cores set for 6 Ghz, 6 at 5.8 and all Efficiency cores at 4.4, CPU is slightly undervolted and so far only PRIME95 running on all 24 cores will cause anything to hit 100 Deg C and it is always the one Performance core, it peaks at 100, but tends to run at 94 most of the time whilst PRIME95 is hammering the system.
Voltages VR VOUT reported by HWINFO, Minimum of 0.742v Maximum of 1.377v CPU Package power peaks at 290.976w
Cinebench R32 multicore 36158 points single core 2315 MP Ratio 15.62x.
It's pointless turning up the power to hit 40k as whilst it will do it, it wont be for long as the cores start to thermal throttle, so yes I can post benchmarks with better scores, but at what power consumption and the extra noise.
CPU Package power consumption running single core CBR32 is 46w as reported by HWINFO

I will post my BIOS settings soon so someone else with the same motherboard CPU combination has something to try as there are plenty of settings and info for pushing for all out performance to be found on the web, but very little about trying for a more efficient setup at stock speeds, OK I still managed to bump the Efficiency cores up a little on mine and have C states enabled so the processor will run at P cores of 1.1Ghz E cores at 800 Mhz and a reported CPU Package power consumption of 12 to 13 w.

Basically this is a 24/7 machine, not a benchmark monster.

Wow, thought I had a stable system until I tried Unreal Engine 5.
Trying to run this caused lots of cpu parity errors which only stopped once I reduced my under volt back much closer to 0.
Yet Cinebench, AIDA, Y-Cruncher, prime etc etc all ran and passed without any slightest issues, but push the CPU to 100%, UT5 compiling the shaders only tended to hit 50% CPU usage and here is where errors cropped up.
I had to delete the derived data cache and the files in %temp% between runs so that it would start the compilation again from the beginning, but now after adjusting voltages etc, I have a very stable system.

It really is worth trying this and monitoring Event viewer for cpu core errors to check if your system really is stable.
 
Turns out the Unreal Engine compilation is a better way of getting a stable system than any other benchmark, stress test.
I had a few minor glitches / issues with my system until I got a 100% clean compilation with no parity errors on Unreal 5.
Yes it runs warmer, but is stable, 100% stable with everything I throw at it.
I had to ever so slightly undervolt my PCH and put a fan blowing on this part of the motherboard to stop excessive (IMOH) temperatures,
But now have a really good nice system which I have slightly overclocked as well.
Wow this generation runs warm compared to my last setup.

I would really recommend you download Unreal Engine 5 and compile something to see if your system really is stable as this seems to really stress test it more than some of the other tests.
Looks like the older way of stability testing is outdated.
