Was lurking at this option for quite some time and decided to bite the bullet this week-end ordering a 2400G in replacement of my 1500X taking advatange of AMAZON 30day return policy if things dont go well

3 main reasons I am trying this move

1) Could not OC the 1500X higher than 3.9ghz at 1.4V even with a recent AIO addition in place of teh Spire cooler

2) CORSAIR LPX RAM would not clock higher than 3066Mhz

3) Selling my GTX1080 now 2nd hand prices are still high in view of funding what new DGPU comes later this year so the 2400g woudl allow me to game, granted at much lower resolution and fps, during that period

Updated BIOS to 4.7 on my B350 PRO4 and post went well, initial test in games show I can OC the chip to 4.1Ghz at 1.4V so its positive for a start

But I found out few annoying issues you might help with

1) I still cant OC to the 3200Mhz its rated for, getting BSOB if OC in the Bios or crash in windows doing so with Ryzen Master software

2) Got an issue while connecting the Board via HDMI, message on screen like Monitor timing input needs to be adjusted balbla.It finally post in Windows but I cant reach the BIOS beforehand.Fix I found is to connect a VGA cable to the same monitor at the same time

3)I have managed to OC the iGPU to 1600Mhz core using 1.15V on both Gfx voltage and SOC voltage while maintaining a 4Ghz CPU OC, but thats via Ryzen Master and I need to restart Windows every time I want to apply the OC and the clocks(both CPU and iGPU)dont scale down after a gaming session even using Windows Power Management.I need to check if Atuning Asrock OC utility would allow me to manage that downclock, at least for teh CPU part, but I a feel I am stuck with the IGPU.

it seems MSI Afterburner is not working to alter IGpu behavior or am I missing something?

If you can share your Thaiphoon Burner nanoseconds, may be @daytonb can work out a set of timing for you.

I have not got my timinng nice, hence I don't have solid solutions for you, just some discussion chit chat only if you don't mind.

btw my CMK32GX4M2B3000C15 up 3200MHZ 

1.365v 

timing is no longer working now, it will not even boot now, I only managed to enjoy 3200 for a week only, then all fails after that. Currently back on 2933.

If you manually overclock you looses adaptive voltage/frequency.

I did an attempt few months ago to recah beyond 3066Mhz on my Corsair RAM using RAM timing calculator tool provided at overclock.net but I was not successful.

I was hoping the new asrock BIOS plus maybe a better IMC in my 2400g would help but early testing days proved otherwise.

I would need maybe to bump teh SOC voltage in teh BIOS but since there are HEX values input,I need to do some correlation work. Really Asrock why HEX????

thanks again for your input

I have seen your several post about how CPU OC would effect the GPU performance. I did last night few runs on project cars leaving the CPU OC alone and OCing the GPU via RyzenMaster(1600Mhz core with  1.15V GFX and SOC voltage as I mentioned in my post yesterday)

Capturing FPS with RTTS and HW64, I dont see significant performance increase or reduced stuttering to be completely honest.I would need to run some proper data logging on FPS and frame times to really see if there are effects at all

I am running my 2400g with an AIO (IDCOOLING Frostflow+ 240, highly recommended considering it cost me less than 60USD) and temps in gaming are in the low 50s and high 60s in AIDA64 stress testing.

that is checking with SV12 sensor which has been reliable to me during my 1500X OCing period.

next week is holiday in Japan so I will ahve more time to do proper testing unless ASROCK released the new AGESA bios

by teh way, found naother issue last night.

I am using a USB keyboard but plugged in the PS2 slot in my MB, which works fine during Boot and in Windows, as it used to be with previous Bios and 1500X chip, but now after my PC wakes up from sleep, the keyboard is not recognized anymore,I cant input my password to get back into Windows!!!!

has anyone experienced this issue? Any new setting in the new Bios I should change to get that issue fixed?

this is really pure annoyance because I did some troubleshooting and if I plug the keyboard in an USB port the there is no issue to recover from sleep.just crazy.

I am also using a Freesync monitor, a Philips 32" with the same range as yours, up to 75Hz.

I used to have the same issues with any USB device plugged in the "Fatal1ty" USB ports, after some time it would just lock and unplugging the device and plugging back in would not work, I needed to change the USB hub completely, but that was using Bristol Ridge CPU, with the Raven Ridge CPU the problem went away, that or the latest UEFI updates fixed it, I don't have the Bristol Ridge CPU to test again unfortunately

but you are using the PS2 ports, maybe someone else can confirm the issues because I dont have a USB to PS2 adapter at hand.

PC would post in windows at XMP 3200 but gave me straight away BSOD whatever Ram voltage I set(tried up to 1.4V) or with SOC voltage at 1.2V (VID 38)

Then I tried the CPU AMD CBS OC setting and went into teh somehow hidden RAM OC tabs in the BIOS to find out that there is another frequency in between, 3133Mhz, and my PC is now running happily at that RAM frequency with 1.35V RAM voltage and 1.15V SOC voltage (VID 40) so its improving

next would be to work out different timings since I have already disable geardown, the Booting stuff and run PROCT at 60Ohm and Cmd  rate at 1T

wish me luck

bumping SOC voltage to 1.1V makes my system stable again so I would say its my sweet spot OC for now.

Did spend some time lats night to see if a NVIDIA GPU would work in current BIOS conditions.It did, installed drivers, ran some benchmark, could do gaming either via the 2400g igpu or the NVIDIA card (disabling one or the other in device Manager)

so it was all good, but this morning I tried to fire up my PC, post the BIOS seemed to load Windows but black screen without keyboard input working

thats so weird, I didnt do anything to the BIOS or touch any windows settings between my last run i n the night and this morning.

guess I will have to spend my evening to troubleshoot again.

Up to 1.4V is ok on Ryzen and DDR4, I wont suggest higher however.

If it still does, can you please disable CSM if its enabled when testing all of this and if its disabled please enable it?

I am happy I can run both GPUs at the same time, the GPU will be used for my triple monitor gaming sessions and the iGPU for just the center one gamming time with Freesync enabled when I dont want to fire up my Rig full power

might not be what most 2200g/2400g have bought their APU for but that gives me some versatility and reduced power usage whenever I want to do some more minimalist gaming

now if I could get this RAM to work at 3200Mhz....

thats the model I have CMK16GX4M2B3200C16 with Hynix

i could have lived with some of the issues I experienced but was also hoping ASROCK would pull up a proper BIOS by now but looking at the complains on this forum, doesnt seem to be the case at least for me as a B350 PRO4 user

1st experience with an ASROCK motherboard, granted a cheap one but I can not tell I am satisfied with the way Ryzen CPU/APUs implementation have been supported.

end of rant, lets go back to OCing the 1500X and get most of the chip
