3200Mhz vs 3000Mhz on 3700X

[SFFDesigns]

Hello!

 

As some of you may know, I've been having trouble running my Trident Z RGB at a stable 3200Mhz (I've tried tons of stuff, from higher voltages to manually putting in timings). At this point, I'm pretty much just gonna stick with enabling XMP and then setting 3000 MHz (timings are 16-18-18-38).

 

Am I losing any significant performance by using 3000 MHz vs 3200? Is it worth trying again (I've been trying for two days straight)?

 

Motherboard is MAG B550 Tomahawk with R7 3700X

Usually Ryzen prefers higher speed RAM, but it isn't a huge deal. if you're cool with your computer being a few percent slower, then 3000mhz is fine. 

if you want the super specific data, gamers nexus does a pretty comprehensive report on this. https://www.gamersnexus.net/guides/3508-ryzen-3000-memory-benchmark-best-ram-fclk-uclock-mclock

 

hope that helps!

thanks! How big of a difference do you think it will be? 3000mhz is still pretty fast right?

 

I'm use flight sims so even 5 fps is a big difference when you deal with 24-30fps 

[Jedimaster99]

haha, I couldn't give you an exact number. if you're really worried about each frame, then yeah, you could probably get at least a few fps out of it. you'd probably get more out of spending some time OCing your CPU and your GPU though.

No you're not. Though 3200 isn't even an overclock for zen 2's imc. 

What values did you put? Make sure the ram is in slot 2 and 4. Set the soc to 1.1 and dram to 1.35 and then try 3200 with xmp.

Yeah that's what was weird.

 

I've tried XMP with DRAM 1.35 and no post at all, I had to clear CMOS.

 

I haven't tried the SOC though, could that make a big difference?

 

I've gotten it to post with 1.37V on DRAM, but Memtest finds an error or two every time. 1.38 and 1.39 doesn't help either

Yea. The soc voltage basically overclocks the io die. So the apu if there's one. The imc etc.

Set it to 1.35 and mess around with the soc voltage. Don't go over 1.2 though. The topology on the Tomahawk is great so that's obviously not a problem. And the imc should handle 3200 easily.

Ok thank you so much! I will try setting SOC to 1.1V and RAM to 1.35V with XMP

[SFFDesigns]

It posted and seems to work @TofuHaroto, but BSOD on windows shutdown. I'm trying a Memtest now, it seems to work though. 

 

If it doesn't (or has an error in memtest, should I increase the SoC voltage to 1.15 or smth like that)

 

EDIT: It has an error in memtest already

Weird. Zen 2's imc should handle it just fine. 

Either way the difference isn't huge. And you won't notice it in the real world.

If you want sure. Just make sure you don't exceed the 1.2v mark.

Ok. Yeah this problem is really weird

 

I'll try maybe XMP Profile 1 (not sure if there is a difference between 1 and 2 but it worked better with XMP 2 with 3000 MHZ)?

Yea try that if you want.

Seems to be stuck on a screen with the underscore with XMP 1. Doesn't let me enter BIOS

yea then clear the cmos and just go with 3000. for all we know you cloud have just lost the silicon lottery sadly. either way as i said. the difference is negligible.

yeah I'll just stick with that. 3200MHz with 1.1V on the SoC seems to work just has errors in Memtest so it isn't stable.

 

 

[SFFDesigns]

@TofuHarotodo you think it's worth trying 1.15V SoC after clear CMOS or will it likely still have errors?

 

EDIT: Didn't post, going back to 3000 MHz

sorry had to do somethings, yea if it did not work the difference is negligible either way. 

something that you can give a shot is manually setting the fclk to 1600 and then try, if you dont want to bother the difference as i said, wont be noticeable.

yeah I probably will just keep it how it is. I can barely count how many times I've had to take out the GPU in the last few days trying to clear CMOS .

3200MHz is guaranteed to work unless the board or the sticks are potato.

Not really, it just means that it doesn't require overclocking anymore. The only that's "guaranteed" is it working at 2133 MHz

So what ya saying is my Ryzen 5 may be potato? :<

No I mean there are a lot of variables to RAM compatibility at different speeds lol

ASRock B450M Pro4 doesn't seem to like G.Skill sticks refuse to run over 3000MHz on most according to the supported list, despite many other brands can when using Samsung B-die wtf?!

Mine was listed as compatible but it ended up not working

Well fuck it, only thing working at better than advertised speeds was my 2666MHz kit in my Intel system... My HyperX Fury kit was OCed to a HyperX Predator spec!
