AMD B350 chipset not supporting decent overclocking, contrary to what users expect?

Recommended Posts

Posted · Original PosterOP

I tried OCing my Ryzen 5 1600X with both Gigabyte and AsRock AB350M mainboards, both failed to OC to 4.00 GHz, didn't give an error report on what cause, just reboots with 3.60 GHz again.

Now I have X370 mainboard, does the job fine. Why did AMD promise us consumers that B350 would support OC if they don't ? Another marketing-lie by AMD?

because your vrms are too weak and you're using a a320/b350 combined chipset?

well your explanation is very flawed , the b350 board can oc but it wasnt as good as the x370 board because of power phases and vrm

yeah, because you either have unsufficient voltage and or the VRM isnt good eough. the fact you can change the multiplier says you can overclock. 

 

try being more modest and patient when overclocking and spend some time tweaking.

Sounds like youre an inexperienced overclocker who got frustrated.

 

B350/B450 can overclock perfectly fine, but thats not even what you have.

 

You got the even cheaper AB350 boards which have weaker VRM's than a standard B350. You could have overclocked just fine by tweaking your voltage settings, plenty of budget builders OC on AB350 boards and have no problem.

Sometimes its cause you may have lost the silicon lottery too dear :) being able to change the clock speeds already means you are able to 'overclock' your cpu.

The quality of the mainboard is not AMD faults,they just provide the chipset, it is up to the manufacturer to design the mainboard.

Don't blame AMD, most B350 board are designed to be cheap alternative to x370, so they cut some component to fit the price.

I did, like was mentioned on TomsHardware (or what it was, don't remember) I set 4.0 GHz and 1.40 V... still failed... So Gigabyte and AsRock didn't keep their promise then it seems, cuz apparently 1.45 V is risky for daily use (according to google forum results).

Thanks for the hint, but no, B450 is even a few € more expensive than X370, strange enough... :P

Apperantly not.

 

4,0 ghz isnt often achieved on this motherboards. And an experienced overclocker should know that 1,4 volts is super toasty. Not to mention VRM power throttling due to overheating VRM.

 

It is not as simple as putting in 1,4volts and 4ghz. Silicon varies in overclockability. 

 

Depending on your motherbord you should stay at 1,35 volts or below.

Wtf is "toasty" ? Negative? Positive? Is there a Freeware somewhere to observe VRM temps?

I got voltage set to "auto" because for some reason in bios it already states ~"1.4" V , where when I set dynamic vcore voltage to +0.100 I fear it does add that to the 1.4V instead of to the default ~ 1.3V Ryzen 5 1600X voltage.

toasty means the voltage is high for B series boards.

 

you motheboard is unlikely to have a temp sensor on the VRMs. maybe hardware monitor will do the trick.

 

never use auto voltage. its way to generous on the voltage. 

 

you are supposed to manually input the voltage or input an offset

Doing bios update now, I already had latest chipset driver. System froze 2 times already while I had a game and other programs open (CPU demanding), most likely related to the CPU overclocking. I enabled "High Precision Event Timer" and "AMD quiet & ..."  features again in Bios. Just tried hardware monitor, working! Thx!

Overclocking to a certain speed is not guaranteed. Sustained (not boost) 4.0GHz and above was a task on the OG Ryzen chips, even on a good board. You're using boards with garbage power delivery and expecting a speed that you'd need at least a midrange X370 to get to stability at. Consider reading or watching one of the many available Ryzen overclocking guides (I think Tech YES City did a good B350 one) then trying again, with the understanding that shooting the moon on your first attempt then complaining on a forum is probably not going to get results.

Whats "OG Ryzen chips" ? And is it true that the system would entirely "freeze" instead of just getting super slow for example? Why does a PC insta-freeze? I'd expect hardware manufacturers/Microsoft to come up with a solution that would alert the user with some kind of "voltage delivery problem" warning in Windows 10 instead of insta-freezing the system and letting the user suffer a 5-10 min. waiting to use PC again after rebooting.

Generally speaking, when you overclock you need to increase voltage to maintain stability. At some point, to get much more increase in clock, you need to add a LOT more voltage. That's the voltage wall. It's the limit that is hard to overcome, and only really done for competitive reasons not normal running.

Have you heard of the term 'silicon lottery'? It refers to how individual chips will vary in how well they overclock. 

For example, my 1500X isn't completely stable at 3,9GHz 1,4V. Others will run 4,0GHz just fine.

What? I get the impression you're massively misunderstand overclocking. 

 

You are guaranteed stock speeds. And not a singe MHz more. 

Anything else is luck. And your own responsibility, should you destroy your CPU or mainboard.

 

AMD is just friendly enough not to forbid you to take this responsibility (as Intel does on most CPUs by locking them to stock) or ask you to pay more to do it (as Intel does by selling unlocked "K" chips for a bit of a premium.) 

 

CPU and mainboards are tested for stock speeds (+ ab bit of headroom for security margin).

Unlocked means, you are allowed to try to get into that margin and use it.

 

No luck? We'll... pitty. But nothing you can complain about.

I'd say the lesson to be learned here is:  Learn first, then buy.  Sounds to me like you were just ignorant to a few important variants involved and how they will effect your outcome.  it's not big deal, you can use this as a chance to learn.
