[Klaver7]

System build =
Gigabyte B650 GAMING X AX V2 r1.x
AMD Ryzen 7 8700G
Kingston Fury Beast KF560C36BBEK2-32 (2x16)
Thermaltake Toughpower GF A3 650W 80+ Gold PSU
WD Blue SN580 1TB M.2 SSD
WD Blue SN580 500GB M.2 SSD (x 2)
Been building AMD systems for years now but this one has got me puzzled.
After this build I ran into somthing strange, without the graphics drivers installed CPU-Z / HWiNFO and shows my RAM clock at around 3000 MHZ stready and should be correct for a 6.000MT/s set.

But as soon as I install the Radeon drivers, with CPU-Z / HWiNFO RAM clock drops down to 999.3 MHZ !
When I run benchmarks the RAM clock will ramp up to around 3000 MHZ, sometimes a bit lower. Now my question is: is this NORMAL for these 8000 series to behave like this .... ?
I started out with the Ryzen 5 8600G and had the same results with CPU-Z and HWiNFO.
Tried different versions of Video drivers but they all downclock the RAM to around 999.3 MHZ at LOW load ! Once again without the Video drivers the RAM clock shows a steady solid 3000 MHZ. Tries dif. RAM on the board but result stayed the same.


Can anybody answer if this is normal or do I have a "faulty" motherboard ???

Klaver7, you cannot see anything on your display without drivers. I do not know what happened, perhaps you switched from the GPU to the iGPU. If you did not get your AMD drivers from here, please do. Perhaps you switched from AMD drivers to down level drivers from MS. I recommend you do a Clear CMOS and try again using latest AMD drivers and post a screenshot of Ryzen Master (RM). If you still get these results try an older version of CPU-Z. John.

That is very strange behavior! I have never seen an IGP downclock the system memory speed at idle.

I do not have any Zen4 to test on, but I have a 5700G with DDR4-4000 and it runs at 2000MHz constant, no downclocking!

Have you tried GPU-Z and does it indicate the same behavior?

I have also never seen CPU-Z indicate 4 x 32-bit memory channel. The 8700G like every other AMD desktop processor has a 2x 64-bit memory controller, so it is strange to see it described otherwise.

[misterj]

FunkZ, I did not see the channel in 4x32-bit. I think the problem is CPU-Z. I run CPU-Z version 2.09.0.x64. It shows 4 x 64-bit, but that is correct for my 3970X. I ask the OP to go to an older version and I will avoid the later one. What version do you have? Thanks, John.

[FunkZ]

I tried 2.09, 2.10 and 2.02 and they show the same on all my desktop systems, 2x64bit as expected.

Yes the Threadripper workstation class processors have quad channel.

@Klaver7 what BIOS version is on your B650 GAMING X AX V2 r1.x?

[Klaver7]

I am running the iGPU, no other GPU in the system, I have a 5600G system behind me here that also just uses the iGPU and the RAM clock on that one is SOLID with the Graphics Drivers. 
Thats why I was wondering if the 8600G and the 8700G had some kinda new power-savings feature ?
btw. HWiNFO shows me the same down-clock after the Radeon Graphics Drivers install.

My CPU-Z version = 2.1.0.0  the latest, HWiNFO also up to date and give me about the same readings:

This one has go me pulling my hairs out if this is Normal for the 8600G/8700G series ?

GPUZ screen-dump

 This is very frustrating ......

[misterj]

Klaver7, what are your symptoms? Is your system slow? Where did you get your AMD drivers? Use an older version of CPU-Z, looks like to me it is WRONG. I do not care for HWinf or many other free applications. Post RM screenshot as requested and try CPU-Z 2.09.0.6x64. John.

[Klaver7]

BIOS = F30
as the latest beta version with the security fix seems to kill secure-boot what I read on Reddit !

System seems to run fine, just the 5600G is almost more snappy at low usage. 
I took your advice and downloaded CPU-Z 2.09 ... BINGO  it's stable readout now:

Now with an older version of HWinfo 8.6.55 I stressed the system and you can see the RAM boosting up to around 3000 and going back down to around 1000+ so that didnt change :

So I will take the older CPU-Z Readout as accurate and ignore HWinfo ?
Hope this is right now otherwise I will get another mobo, but if it behaves the same it would be a waste of money. Thank you misterj !

[Klaver7]

Oh almost forgot about the Video drivers tried both from Gigabyte and here from AMD.
Running the AMD 24.5.1 - 31.0.24033.1003 right now as they are the most stable.
Thank you again

[misterj]

Klaver7, I always ignore HWinfo. Even the older CPU-Z says 4x32-bit in Channel. I recommend you remove ALL MB applications and HWinfo and see what CPU-Z says. Use Ryzen Master (RM) as recommended above (an screenshot). John.

[Klaver7]

It tells me that EXPO is OFF while it's on in the BIOS ...  Strange stuf.
Hope this is what you meant with RM screen-dumps
Thank you again

[misterj]

Klaver7, this is great thanks. How did you set EXPO mode? If you set it in BIOS, this may be what happens. If you set it if RM, you have found just one more RM bug. Please report it by clicking the Bug icon in the upper right corner of RM and include the screenshot of Basic View above. Both Basic and Advanced modes know that the memory clock is 3000 MHz (6000 MT/s). Would like to see the requested screenshot of CPU-Z after removing what was specified above and a Clear CMOS. Thanks, John.

[Klaver7]

I always set the "XMP" EXPO in the BIOS, I never use Ryzen Master as it caused me some headaches in the past and I am not an overclocker.
"remove ALL MB applications" ? I never use the Gigabyte App stuff, toggled OFF in BIOS.

All that is installed is the latest AMD Chipset drivers 6.07.22.037 and the AMD Video drivers AMD 24.5.1 - 31.0.24033.1003 BOTH from here AMD site. Had problems with the Gigabyte APU driver. crashes, green sreens etc.
AMD drivers are rock solid !
No errors in the windows event log or problems.
OK BIOS reset and tweaked again, took a while but done.

CPU-Z V2.0.9

CPU-Z V2.10

So going on your reply earlyer I will just ignore CPU-Z V2.10
and just go by CPU-Z V2.09
So you say that the MOBO = OK ?
Thank you for your help

[misterj · Accepted solution]

Klaver7, OK. If CPU-Z has an error reporting port, please send them these two screenshots and explain that your processor has 2x64-bit channels. John.
