I also have that option in my Prime X370 Pro. But it looked so complicated that I Left it alone.

I'm taking a wild stab and bare with me.
205 x 10 FID / DID = 2050 x 2 = 4100mhz as which I am at now. If I increase FID to 210 that brings it up to 4200mhz.

So currently testin tweaking Memory from 1066Mhz SPD is 15-15-15-36-50 jedec #7 or 1066Mhz 16-15-15--36-50 jedec #8, Currently tweaked to 13-14-14-34-48 1T 1.2750v. Seems to boost performance similar to raising memory speed to 2400mhz. No stability testing aside from leaving it run normal operations and gaming with a few benchmarks thrown in here and there IE Cinebench R15 score ok for the clock speed making the highest score I've accomplished yet.
Also playing with FID and DID again. will slip results in later maybe. Got some more testing to do with frequency in bios vs what Cpu-z reads in windows. While I post 4220Mhz Cpu-z claims 4190mhz. Cpu voltage is on auto.

This is FID 168 x DID 8 @ 4200mhz. Mem is at 1066 14-15-15-38-51 1T 1.2750v. This is 24 hours stable enough for me. Memory at 1066 13-14-14-38-48 1T does not pass stability testing.

I did come to the conclusion that DID 8 is stock.
So is DID 10 and overclock? Or is DID 7 an overclock.... Either way, you increase DID to 10, you increase FID with it to accomplish like frequencies. So I'm not sure which way to go while I get some mixed results while playing with memory frequencies at different FID and DID configurations.

Hi Shrimpy, here's how it works: CPU Ratio = FID x 0.25/DID x 0.125 In your case it seems the numbers are decimal so that makes it easy:
In your post above you have FID = 168 and DID = 8 so your CPU Ratio is 168 x 0.25 = 42 and DID = 8 x 0.125 = 1 so the CPU Ratio is 42/1 = 42 and you get 4200MHz with 100MHz bclk.
In your earlier example you had 205 and 10 which equates to 205 x 0.25 = 51.25 for FID and 10 x 0.125 = 1.25 so your CPU ratio was 51.25/1.25 which comes to 41 for 4100MHz at 100MHz bclk which is what you had.
I have a feeling the highest FID is 255 and the lowest DID is 8 so the max CPU Ratio is 255 x 0.25 = 63.75
the max AM4 CPU frequency on the bot is 6000MHz using 60x so the CPU ratio limit has not been reached.

so in other words its your multiplier or am i reading this wrong ?

It's the multiplier in decimal. I totally get it now...

these fuckheads than name all the stuff with all this new bullshit terminologies in the bios settings, should have their balls sliced and quartered just for the sake of it, and id be happy to do it too, makin it hard for every one when it could be so simple
when i looked at what cas said , i said thats a multi, why not just say multiplier in the bios instead of DID , FID or whatever it is, this might help. % multi applied.................... its a wonder they didnt come up with a FUK bios setting to choose from, coz thats what its gunna end up doing to boards , or is that the plan to fuck it and buy another one, arsewipes they are !!!!

Well hell I don't know!! The tab says multiplier and boom FID and DID. it goes up by .25. Be damned you can find stability fooling with quarter of one multiplier.
My problem is I cannot change the dang bus, reference or bclk or whatever new name the not the multiplier is.
OK so at least the memory stuff looks normal. That I can work with. IF THEYD GIVE ME A USEFUL BIOS UPDATE TO ACHIEVE SPEEDS BEYOND 2400MHZ FOR Funks sake, I'd be getting somewhere.

My ryzen 1400 is running over ddr4 3000mhz and the board has no processor oc features. It did the same thing until a year later Pete suggested a bios update and BAM! Ram oc like a champ.
This board is pretty fresh yet, so its a bios update waiting game.

I'll take a screen shot of the Ryzen 1400 and the A320 chipset rocking out 3000mhz Memory frequency sometime this evening. It's been on a full load folding for team W9 since yesterday and still up and running now. So I know it's very stable. Stay tuned!

OK this is Ryzen 1400 with A320 chipset. If the size is crazy that's because I am running a 52" monitor 1080P

Heh, interesting fact, that Asus Prime A320 actually supports the Ryzen 2700x.... ideas start brewing.... will the cooler fit in the case.... looks really really close. Where's my feeler gauges?

when I think of no OC'ing on the base boards, I think of Ratio and FSB. memory ratio's I'd think would still be open except on server grade gear...

Yea, the A320 chipsets only offer Memory overclocking. At least the one I have does. I'm slightly over XMP. And the timings where auto selected. Hey whatever works. It's a family rig, so I don't push on it. Just glad it can achieve XMP profile frequencies.

FID = Frequency ID DID= Divider ID CPU Multiplier = FID x 0.25 / DID x 0.125 This scheme allows CPU mutipliers to be changed in increments of less than 1 which is useful if the board does not have an external clock generator. Playing with DID will give you overall lower max CPU Multiplier but you can reduce the increment, for example with DID = 12 the increment drops from 0.25 to 0.167 with 42.5 possible at max FID = 255. Of course when you have a clkgen bclk comes into the picture you have a whole other level of fine tuning. The C6H can increment bclk down to 0.20 or 0.25MHz which is really useful whereas the B450 Strix Gaming only does down to 1MHz which is less useful but still better than nothing. What's the smallest increment for CPU Multiplier on Intel platforms? (in the modern age with a $$$ K SKU, obviously)

Wait.... ClockGen supports AM4?? Gotta linky>?

With the C6H I can use the bare boned ASUS TurboV in Windows the change all of the things. On the Strix B450-F Gaming it works but only for the voltages (maybe CPU Multi too, can't remember).

So there is no way of increasing the reference clock or bclk?

OK I see thank you for all the help!
The Asus Zenstates only works for summit ridge processors. bummer.

Had a look at the C6H bios and the FID goes from 16 to 255 and DID from 8 to 48 so in theory at 100MHz bclk you could run the CPU at 67MHz

Post by ShrimpBrime on Dec 12, 2018 16:36:27 GMT -5
Interesting. I've gotten it down to 550Mhz with a 5.5 multi. See?

Post by cbjaust on Dec 13, 2018 2:23:16 GMT -5
That's cool, can you ramp up DID and go lower?

Post by ShrimpBrime on Dec 13, 2018 16:33:33 GMT -5
I suppose I could try to go lower. Thought 550Mhz was slow enough. Took a couple of minutes to post windows from the solid state haha.

So there is no way of increasing the reference clock or bclk? I can't do it on my board either Jon. To properly tune these chips we need to get the boards that everyone was telling us in the beginning we didn't need. Well, yeah we need the likes of the CH6 to get these things to tune in. I will get one eventually. For folks like us that like to get down into it and tweak and tune they are a necessity. Just my 2 cents.

Well if the darn Cpu and memory wasn't so darn expensive, I would have gone with a top board like I've always done in the past. But because they got decent processors now, AMD can charge a better dollar for them. DDR4 isn't even new anymore. Just expensive. Since my 2700X is more of a gamer, I don't need a fancy board for sub zero. It clocks on par with what I've seen. I'm happy with the cheapy board honestly. Handles the Cpu quite well. Even the stock cooler does a great job IMO.
