Linpack Xtreme Released

[RJARRRPCGP]

unless there is some background service that consume a lot of memory.

I know that I have with another RAM kit before, ran those other tests with no errors. Is Linpack silently failing to allocate RAM, because of NT 6/10's OOM'ing BS and causing truncated data?
In my case, it could be a service or the like, for all I know. For all I know, I may be changing tons of voltage settings for nothing.

I saw an issue like this with FX8350, as well! So I went to Prime95 and it always looked good in Prime95, when it's not related to core testing. Linpack is excellent for core testing, but don't know about anything else, as I also saw Linpack not reveal a bus instability before, that Prime95 blend did.

Note that I have a new 32 GB RAM kit that I didn't even try to use yet. It's G.Skill RipJaws V 3200.

Is it normal to have many variations in the residual values on a stock i5-13600K? I find that I have to disable ecores to get the residual values to match over 90% of the time. Do I have a defective CPU or ecores?

I think for anything from Intel 12th gen onwards it can happen. The main thing is that there is always a PASS and not a FAIL, then you are good.

It's normal for CPUs that support AVX 2 and above.

Thanks for the responses. Is it something that happens with Zen 4 as well?

Nope.

A little is normal I think.. mine fluctuates with temperature, when it is cold in here I can see very little change in output

So, will there be any updates? I mean, it's been 3 years according to first post...

Does it need to be? Run it and see what happens.

I noticed my residuals match a lot more often with my ram at auto than with XMP. Like 10-30 of the same residuals in 50 run sets versus just 2.

I’m using my 13600K with Corsair Vengeance 32GB 6000 CL30 on an ASUS Strix Z790-A II.

Is having fewer matching residuals on XMP a sign of subtle memory instability or does it not matter? I would think that my system spec is strong enough for a 6000 CL30 kit. My system with XMP on passed dozens of hours of Karhu, TestMem 5, and HCI MemTest, for what it’s worth.

Edit: Oof, my PC shut down during a no AVX2/ecores off run after around 15 trials. It then finished 50 trials the next run. A fluke I hope.

I remember even Buildzoid from "Actually Hardcore Overclocking" saying in one of his videos that he previously took non-matching residuals as a sign of hidden instability of sorts, but ever since 12th gen at the latest, he disregards it, because there it can happen even with a totally stable memory system.

Your system should have no problem with DDR5-6000, yes. Provided you are on a recent enough BIOS version and your IMC is not a total dud.

About the PC shutting down, have HWinfo64 Sensors open, with all the sensors expanded (the <-> symbol at the bottom) so you have three big columns of sensors at least, then monitor the power draw and temperatures of everything. A 13600K, depending on your cooler, can overwhelm your cooling in Linpack, or whatever else might be going on.
