Newegg listing November 2nd and 3rd:



Newegg listing November 4th, today:



Did Newegg sell out their known incoming quantity of boards as Pre-Orders in 48hours? OR did they simply change the purchasing status?

Who knows right?

Did anyone grab a pre-order?

For 8400MT/s,.. I need to adjust the CPU Input Voltage VCCIN_AUX, remove from [Auto] and set to 1.95v.

VDD: 165v, VDDQ: 165v. Frequency 8400. Primary's 38-50-50-128. my IMC has a rough go with 8400 running 2x16GB 7200MT/s kit, so YMMV with better binned kit, you can most likely tighten primary's.   

Everything else I leave in Auto. And system applies SA: 1.310v, IMC: 1.50625v, VDDQ TX: 1.356v. 

See if that helps you get 8400 stable.

For me leaving VCCIN in Auto was issue, my system only applying  1.76v,.. bumping it up manually resolved issue.

Congratulations achieving 8400 stability! That's using your 7200 kit?

How about your 8200 2x24 kit?

[Braegnok]

Thanks, yes with the 2x16GB 7200 kit,.. 

When you build your Terra PC, here is a nice set of keyboard caps to match chassis.

[iBruceypoo]

That is nice, thank you.

Really love soothing greens. Getting the Fractal Terra case and Seasonic SPX 750watt PSU platinum in white together next week.

Then hoping for an ROG Z790 Impact ITX board to announce for Raptor Lake Refresh. 

[Braegnok]

The SeaSonic SPX 750 is nice,.. they now have 1000W SF units. 

You might look at the Corsair SF-L Series SF1000L. https://www.corsair.com/us/en/p/psu/cp-9020246-na/sf-l-series-sf1000l-fully-modular-low-noise-sfx-po...

Both my itx builds I used 700, 750W SF PSU, as that was the largest,.. it limits the GPU, CPU, AIO,... 

[iBruceypoo]

Company finally left - everyone exhausted. 

So you know what time it is Sir Braegnok? Imported from Austria John. lol 😁

I'm just kidding around. lolol 🤣

[iBruceypoo]

Some nice build photos and 8200 34.

[iBruceypoo]

1.56v VDD/VDDQ as a daily does not scare me - Noctua 80mm DDR5 fan working well at 55%. 👍

I might be a terrible DDR5 overclocker, yet I can still smell a sweetspot. 

Looks like I'm running 6.2Ghz 8Pcores 8200 34 until Panther Lake. 👍

[Hopper64]

No. Don’t see a setting for round trip latency. 

[iBruceypoo]

Round Trip Latency is under subcategory Memory Algorithms under Memory Timings. OR do bios Search.

It was a must to Enable that setting for Z590 DDR4 5866MT CL21 stability. Some good guys over at OCN are using it this gen Z790.

Maybe Silent Scone can let us know if its absolutely needed with A-die.

Yes John, 5866MT/s CL21 DDR4 was really a thing. lol Braegnok and I were running Gskill 5333Mhz XMP kits with Z590 Apex at:

5866 CL21

5600 CL20

5333 CL19

...with Hynix DJR way back in 2021. lol  😄
