Welp finally was able to downgrade the bios. Had to pull vga and ram and remove cmos battery for a minute and Flashback+ was
able to downgrade to 1.6.

System is much better now since I downgraded.

1.47 volts is excessive and will definitely degrade the life expectancy and performance of your memory over time.

They comment that b-die memories work well up to 1.50v. I use an 80cm fan on top of it to cool, it's only 40c.

Many models nowadays are sold with 1.45v, so I see why you worry so much.

Only because it is rated at 1.40 volts at the high XMP frequency. being 5% higher 24/7 will degrade performance slightly over 2 or 3 years.

How do you use 24/7?

Was your cmos battery removed during the flashback procedure? Tried to downgrade v17 bios to v15 on my B450 Tomahawk, removed the graphics card, RAM, pulled out cmos battery and reinserted it after a minute. Then tried to flashback, the flashback+ light flashed for 2 seconds then stayed on until I turned off the PC, v17 bios remained.

I tried both ways with it in and out, with it out it worked. Also make sure nothing else is on the drive and the pc is off. I had that problem also it only flashing for few seconds.

Could you explain a little more please?
I have a MSI x470 Gaming Pro Carbon that with latest bios PBO Scalar dissapeared and can't flash previous BIOS.

Thanks!

"Many of you know that I have often recommended X470 GAMING M7 AC. This board is one of the best that is now on the shelves. But at the moment I have to warn all users. Zen 2 support is not currently available. Deception."

Your deception? There is beta bios 1.94 on the MSI site for this motherboard that supports Zen2 cpus. I am waiting for an official 1.90 bios before I apply Zen2 support.
My gut deeling is the vrm support on this board will be inadequate for the 3900X and 3950X. It is barely adequate for the 8 core 2700X. I am now getting 85 Celsius temps running at 4.2 GHZ with the Prime '95 torture test with small FFT form factor for maximum heat. I have one of the best expandable AIO's on the market the Alphacool Eisbaer Extreme 280mm thick radiator. I have the pump close to full speed at 2700RPM and the fans maxed out. Of course I am in a sun room. During the day with the AC blasting the ambient temp is almost 80 Farenheit. So that is a contributing factor, but not the nain factor. As soon as the MSI X570 Meg Ace is released I will buy it if it is under $350. It has superb vrm and power phase support. I think thaty plus my Ryzen 9 3900X will run a lot cooler than this overclocked 2700X.

The statement is quoted. Therefore not my deception. And I don't use that mobo. I have the CH7, which is good.

And according to AMD Travis Kirsch, it is stated the the best Ryzen 3000 for overclockng, it’s definitely not going to be the Ryzen 9 chips.

So, my rig is going to be CH7 and 3700X.

It should make no difference in overclocking whether a 12 core , 16 core, or 8 core, not with chiplet technology. The deciding factors are the binning of the cpus and the extent of cpu cooling in place.

if you are talking about your CPU temp then VRM won't make any difference. I get the same temp running an overclocked 2600 or 1700 on a B350 tomahawk as I do on the gaming m7 ac. saying you get 85C running prime doesn't mean anything without voltage input. You're also in a hot room - drop that temp by 6c and your torture test temp will drop by around 6c as well. That being said I bet your day to day results are much lower given the unrealistic load prime 95 puts on a cpu.


VRM will be more than adiquate even for the 2950x on the gaming M7

Hi there,

Meanwhile there is bios 190 out.
Is there a benefit for 2700x, meaning ram stability, oc capability?

Has somebody tried?

I read something unspecific in another forum from just one user.

Best wishes

Currently running a 3900x in this motherboard. No issues to report. Boosts well and almost see 4.6 in single core activities (ab bios). Vrm temps are totally fine around 55-60c
