New Build Consistent crashing during gaming...Memtest failures.....

Andy Armstrong · 19 Apr 2023 at 13:53

Hi all!
I have a new build as follows:

Asus ROG Strix Z790-E Motherboard
G.Skill Trident 32GB Ram DDR5-7200
ASUS ROG Strix 4070Ti
Lian Li Dynamic o11 Evo
Asus ROG RyuJin II CPU Cooler
Intel i5-13600KF
Windows 10

--------------------------------------

I immediately experienced complete game cashing, no error messages, sometimes to desktop, sometimes the whole PC crashes forcing restart button presses. I decided to do a Memtest86 test of the RAM from my motherboard Bios and each test has failed, under all configurations of XMPI, XMPII and XMP 'Tweaked' (which are all the available options to me in the A.I Tweaker in the bios). Each of these settings has a target frequency of 7200 in ram.

Please see some screenshots of the test results below:

I don't failures like this are normal but it's been a long time since I did a new build. G.Skill RAM look faulty to you guys?

Do you get errors when you run the memory at stock (with manufacturer recommended voltage)?

Wing-Man · 19 Apr 2023 at 21:46

7200mhz is up there pal, try xmp with the clock lowered a little

Also is bios up to date

Andy Armstrong · 19 Apr 2023 at 21:48

This is stock! With the recommend voltage.

@Wing-Man as I said in my post - I have tried all 3 variants of xmp, and also updated the bios to the latest March release last night - didn't alter anything.

Wing-Man · 19 Apr 2023 at 21:49

Try the base xmp but manually reduce the speed yourself to a little lower.

You sure? In the screenshot it says it is running @ 7200?

What’s the spd none xmp speeds,

By saying run at stock I was saying without XMP enabled, with a 13600K the max stock frequency is 5600 for 2 sticks. This should help you to check if the memory is just faulty faulty, or if there's a specific issue with the speeds it is running at, maybe the timings, frequency or voltages (or even if the CPU/motherboard doesn't like it).

Andy Armstrong · 21 Apr 2023 at 12:32

@Tetras
Maybe I don't understand fully the importance of some of these settings.
My understanding was I can just enable XMP and be done with it.

The RAM is DDR5-7200 16GB x2
CL34-45-45-115 1.40v.

Can you share how you determined the max stock frequency under the 13600KF?

The maximum supported memory speed it 5600mhz this is what intel say will 100% work. Anything passed that is an overclock and as such with differ from cpu to cpu.

This is why I said reset bios so your at the base speed and retest

Intel® Core™ i5-13600KF Processor (24M Cache, up to 5.10 GHz) - Product Specifications | Intel

Intel® Core™ i5-13600KF Processor (24M Cache, up to 5.10 GHz) quick reference with specifications, features, and technologies.

Ah okay.
SO - now retesting at the Reset default speeds, which has put the RAM at 4800mhz... will post the results.

If I then tried anything above 5600mhz....is it is an 'overclock' ? The RAM is DDR5-7200....so this is 'underclocked'? , would the CPU have to be overclocked in some way to work the RAM faster than 5600mhz?

The ram will pass a test now. When you need to do is set ram at XMP and manually adjust its speed starting at 5600mhz and work you way up to find the max speed your CPU’s memory controller can take.

The ram will be tested at 7200 but they can’t test on ever memory controller, and intel can manually test every memory controller before it leaves to door. So they test in batches and workout what they think will work on ever cpu

@Wing-Man thank you for explaining!
lll do exactly that.

In my bios (ASUS ROG Strix z790-E) it has XMP I, XMP II and XMP - Tweaked.
Which makes sense to use as I select one and manually adjust the speed from there?

Andy Armstrong · 22 Apr 2023 at 14:01

Well the tests passed clear until hitting 6800mhz.

Stepping back to 6667mhz passes.

Now you can loosen timings to see if it will higher or tighten timing to see if you can go lower but 6667 is good. I would work on timing orrrrrr ever just stay as it and be happy
