Don't blame v-color if you have too hot dimms and maybe a memory controller that doesn't like the speed. There are many factors that can be the issue

First take away the issues that you can do something about. Like cooling the dimms.
Take a picture of your pc case maybe?

The Board most defintely can do it

I wonder if QVL lists it.
But very little % of CPUs exceed 8200-8400.
A lot of people fight for 8600 to this day since months, or even over a year.

If you got the DIMMs on a good pricetag, keep them downclock and tighten timings a bit.
You did pay for the Board that can support it & the DIMMs who were verified to run stable under normal conditions.

But if you have trouble with the CPU and signal is finicky, then DIMMs won't be able to handle it.
Close to all errors say for you a #4 which is DIMM PCB Crash
Why, probably because voltages are too high from CPU side or PCB is unknown and struggles.

It definitely will struggle with higher temps.
You always have tradeoffs somewhere.
First is high temp = unstable.
But nobody can tell you if your CPU is fine with those unverified speeds. Mind you JEDEC 4800 rated only

Downclock from 8600 to 8400
Or down to 8200
If you are still high thermals unstable, it's probably the RTTs and the DIMM-Vendors PCB used.

Non of both mean they are defective for RMA.
But I can see one wanting everything to work out of the box.
It should.
But there are far too many DIMM-Vendors out, everyone doing their own thing.
At the end, it likely is just a settings question, or you undervolting your CPU too much + another variable why DIMM cause trouble.

What about my poor TM5

Why this motherboard not showing MC score? I don’t know which processor to keep, my 13600K or 14600K, when both are overclocking to 5.8GHZ with 1.28V, so the difference would be in memory overclocking. However to test it out which have better IMC is too difficult.

maik73 · Aug 16, 2024

I would like to set the RAM voltage in my ASRock Nova (BIOS 6.02, Intel 14700K) to a fixed value of 1.35V. My memory is the model F5-6400J3239F24GX2-TZ5RK (Trident Z5 RGB, DDR5-6400, CL32-39-39-102, 1.35V, 48GB (2x24GB), Intel XMP). Under which BIOS option can I find this setting? So far, I haven't found anything.

I have another question: How can I reduce the peak turbo frequency from 5.6 GHz to 4.8 GHz, so that the system also follows power-saving measures during operation and throttles down when full performance is not needed?

Thank you!

Got the Asrock Z790I Lighting.
14700KF and 2x48GB DDR5-8000 = 8000 CL36 stable.

Everthing above 8000 is n o t possible.

Change to my old 13900K.

8000 stable. Everything above 8000 n o t possible.

Maybe i will test the lighting with my 13700KF.

So, everything that is written about the different voltages, IMC, SA, ODT that do magic .... bla bla ... will help a little bit.
First you need an apex or Asrock Lighting. Second you will need an very good CPU aka golden IMC (KS).

Then u can do 8200\8400\8600.

With my apex encore, that kills my 14700K ... max (with the my cpu & ram) was 8000. 8200 n o t possible.
for 280 bucks. Yeah. Nice work from asrocki.

verdict:
the assi can do the same as the super apex, but for 1/3 of the price.

it was good ... to send my apex encore back to the reseller and got my money back.

until arrow lake 285k & camm2
i 'll sit back and look at the ryzen 9 release

u need linux for better performance

u need super admin rights for better performance

u need a fresh win installation for best performance

Many bugs everywhere
But both platforms are fun.
You'll get used to the Zen experience, but it's very different.
Need to watch closer how boosting algo functions & need to verify things are not throttling (always are)
But overall stability is easier to maintain just algo is wastly more complex.
// internal sheduling fast, OS sheduling slow & missbehaves ~ complications, haha

Unsure if Arrow will get difficult and fun
But Zen ecosystem can be frustrating but can be also a great adventure. I don't know yet,
But usually up to the users taste

Both probably run plenty fine out of the box,
It's usually the high expectations that find small issues and bugs 🤭
Both for sure will be fun & hopefully different enough.

What temperatute did you got under load on your dimms?

Too bad Lightning only is itx, so that makes it useless in some scenarioes. Like I can't use my Optane pci-e x4 storage on my Lightning 🫤

I did 8400 on a 13900kf, 8600 2x 14900ks and 8600 on 13900ks. On Z790i Lightning.
Haven't tested my 13900k yet.

Just try booting 9000 with 1.35 SA, 1.4 TX, and 1.55 VDD2. Booting 9000 is a good sign.

MC score doesn't matter. It takes effort and time to test imc. If you don't want to invest time to it, then run "xmp"

I only would make time for the better processor to test out the max MHz for memory. Unfortunately don’t have idea how to test out quick way, which processor will overclocking memory better. Sweet spot for SA and MC voltage can be different and so on…

No way would booting at 9000MHz, I have the Nova.

Then that is your limiting factor; likely not the CPU.

I got 7600mhz max stable on Nova. With the same cpu and ram, I'm running 8600c36 on z790i Lightning

Same here, but with a turd Apex Encore max stable was 7800mhz, with same CPU and RAM 8600c36 on OG Apex Z790 and Lighting Z790i, you need to have all 3 components top notch to achieve +8000mhz.

Guys I want to ask something. I have the glorious model o mouse. Sometimes and rarely when I turn on the pc (nova and 14600k) I get an error that says usb device not recognized and the mouse is not working. The mouse is connected in the phantom gaming usb port. Any suggestions?

tonyptony · Aug 18, 2024

Minor issue, but I can't seem to get a PS2 mouse working with the Lightning WiFi board. I set Super I/O PS2 Y-cable to Enabled, but the mouse isn't working. Does any other setting need to be updated? Yes, I do normally use a USB mouse, but I'm trying to test everything on the board and this doesn't seem to work.

Try to change usb port

Usually it's not hotplug but you'd know that.

Please test if win can detect any COM ports and enable serial port too
Just in case

Dev manager reports the port inactive with a yellow triangle ?
Had this with an ES Raptor-P. Chipset was Frankenstein and official chipset drivers caused it

But if the mouse isn't working in the bios even, then that's some configuration issue.

Those devices (tho have the same pixart sensor)
Usually come with 3 HIDs as one device
A keyboard, a mouse and a communication driver.
Maybe BIOS gets confused, but also maybe it's just XHCI and USB 2/3 transition.

Please verify if the Mouse functions in the Bios & which of the ports cause you issues.
Will help with figuring out the main issue, vs the side effects.

Hey guys,

Just updated the BIOS on my z790 Nova from 4.13 to 6.02 (14700KF) and I am a bit confused by the test results after the update. After loading default settings, I applied the same settings in BIOS as before. Undervolting applied in FIVR: Core voltage mode: adaptive; VF offset mode: legacy; VC configiration scope: all-core; core voltage offset: -110mV.

Cooler settings, fan and water pump speed and room temp are all the same as before.

Test results:

BIOS 4.13 - 10min CB23 run:
Max temp (CPU package): 76c
Multi Core Score: 36k

BIOS 6.02 - 10min CB23 run:
Max temp (CPU package): 81c
Multi Core Score: 35.7k

Has anyone experienced anything similar? I am really surprised that my temps increased after the update. I am sure it is due to the update as I ran a CB23 multi core test just before the update to have measurement data right before and after the BIOS update.

It seems I now have to apply -190mV to get the same temps as before. The interesting thing is that with the old BIOS I could not pass CB23 with > -110mV applied. Now -190mV offset seems to be fine. I really hope I won't run into stability issues as that would mean I need to decrease the offset, which would result in higher temps than before the update.
Unfortunately, I don't have vcore data with the old BIOS so I can't reliably tell what the vcore was exactly back then.

Greatly appreciate your help.
