Ryzen 7 1800x - Can't get to 4.0GHz

[LichtorWright]

I don't usually post on forums like this but I'm -so- confused about what's going on here.

 

I can't get my 1800x to 4.0GHz stable even at 1.4v. Normally, this wouldn't be surprising. However, my 1800x has NO problem going to 3.925GHz at 1.338v. This is below stock voltage.

 

How is it that I can get to 3.925GHz - BELOW STOCK voltage, but can't get to 1.4GHz going to 1.4v.

 

I have no problem keeping it at 3.925GHz because, well, lets face it.. a nice overclock below stock voltage is a huge win. (My temps get down to 21C idle - Maxed out at 58C running prime95)

 

My hardware:

Ryzen 7 1800x

Asus Prime x370-a

TimeTec 32GB (2x16) 2400MHz (it's cheap, I know)

CoolerMaster MasterLiquid 240

my friend you lost the silicon lottery 

[flibberdipper]

Welcome to the land of overclocking, where not even a jump from 1.4 to 1.6v can get you that extra 100MHz beyond a certain point.

[ARikozuM]

Ryzen averages around 4.0GHz and you're within that average. 

How is it that I can get to 3.925GHz - BELOW STOCK voltage, but can't get to 1.4GHz going to 1.4v.

This I can't explain, AMD may have sent you a sh#t covered CPU as a personal vendetta.

this!

 

No one chip is the same. some chips can get to 4.5 no problem, while others have trouble getting to 4, no matter how much voltage you pump through them.

 

This is because in the process of manufacturing processors you can't make all chips evenly. some chips are more 'prefect' than others. This is what is known as the sillicon lottery. sometimes you luck out with a good almost perfect chip (AKA a lottery winner), but sometimes you get a poorly manufactured chip (AKA a lottery loser).

I went through 3X Ryzen 1800X CPUs to get one that's capable to hit 4.0Ghz. All the other ones did 3.9Ghz. Voltage will not help.

Try voltages below than 1.5 but higher than you're 1.4. Screw around with blck or something. Otherwise, you just lost the silicon lottery. It's only an extra 100mhz. Just take the loss and move on.

[LichtorWright]

I mean, I have no problem with the 3.9GHz.. it's still way faster than my FX-8350 and SIGNIFICANTLY cooler than letting XFR do it's thing.

 

Running this stock, voltage was hovering at 1.41+ with XFR turned on and hitting 75C on temps quickly (right after installing, so I'm sure thermal paste had something to do with it)

 

I'll play around and add a little bit more voltage to see if I can hit that 4.0GHz mark. I just thought it strange that I basically hit a brick wall.

 

Edit: Took it up to 1.425v and it still wasn't stable. It took a little longer than normal but prime95 still failed and I'm just not comfortable taking it up anymore than that for 75MHz. Took it back down to 3.925GHz and reduced the voltage to 1.325v and it's rocking.

 

A 225MHz overclock on 0.025v less than stock is still pretty good. I wouldn't run it over 1.4v anyway, it's too hot. My FX-8350 never got over 35-37C unless I was stress testing. The 1800x is definitely a different kind of beast.

Yeah Ryzen is voltage limited. My 1700 is stable at 3.9 using 1.35 V, but I need 1.47 for 4.1.

 

Nonetheless, it looks like you got unlucky. Most (67%) 1800Xs hit 4.0 GHz around 1.41 V according to siliconlottery.com.

wait what?! my ryzen 7 can only go 3.8GHz at 1.35v . need 1.46v for 3.9GHz. im in indonesia, using Noctua NH-C14S and Raidmax Element case. is that ok to go 1.46v all day long? or just go back to 1.35v?

I've never heard of Ryzen getting 4.5GHz.

Does your board have CPU Load Line Calibration (LLC) bios settings? What options, if available, does it give you?

Yes, it has "CPU LLC".. 5 options are available:

Auto

Regular

Medium

High

Extreme

 

I had been keeping it on High but during the last test, I switched it to Extreme, to no avail.

Here's problem.

Take the 1800X off that motherboard if you dont want your house to end up in a pile of ash

I am surprised the motherboard didnt explode yet

Stop fear mongering, you're not a news station. Everyone knows there's a chance with any motherboard CPU combo; some more than others, but just because I'm not running a $350 motherboard doesn't mean it's going to implode.

Measure the VRM temps

You will be greeted with a 3-cipher number.

Overclocking 1600 can get that VRM toasty. 1800X (especially the crazy mumbo jumbo you're doing over there) will put it over 100°C. In your case at least 110°C, most likely 120 or 125. At that point you have 800 hours of capacitor life.

I have no way of checking the temperatures externally and I can't find any documentation that describes the temp layout for this board for things like HWMonitor.

 

The board has a 6 phase VRM, the heatsink was barely warm to the touch during the testing.

 

However, I found the Asus Prime x370 Pro for about $30 more than I paid for this so I'm returning it and getting the Pro. There are better fan headers and it has a 10 phase VRM. A few other nice features that the x370-a doesn't have.

 

When I purchased (and still does) the x370-a, it had the best reviews on Amazon of the cheaper x370 boards (5 out of 5 stars). The VRMs on this board don't really scare me, but the extra fan headers and a few other on the Pro is very appealing.

 

I don't so much care about overclocking the CPU. I just found I had better temps on the CPU after manually setting the voltages. This motherboard was ramping up the "auto" voltage for this CPU to 1.42+v at stock. Not cool!

 

I suppose, though, by manually setting the voltages and increasing the LLC, I was putting extra strain on the VRM.

Bullshit.

This VRM gets warm-hottish while stress testing 1600 at 1.4V 3.8GHz.

Here is what it looks like on Strix B350 mobo (R7 1700X 1.4V 3.95GHz):

https://drive.google.com/file/d/11w0V4KrpKme_11GrLXn_tJCta10eTANJ/view?usp=drivesdk

I had the Strix motherboard and know the VRM pretty well. Here is a full picture of that VRM.

It is rather very weak VRM, 6 core OC at max.

I took some pictures if you are interested

Its 4+2 VRM

Yes, Prime X370 Pro has a great VRM even better than some of the top of the line motherboards.

Never take those reviews seriously, especially with motherboards

Just because professional overclockers got 5.4 Ghz using methods like delidding (much harder on AMD) and liquid nitrogen, plus having the money to go through several chips to win the silicon lottery, that doesn't make hitting 4.5GHz anywhere near easy for the standard user.

Would this mean that in my case I got lucky? I am just using a cooler master 120mm AIO, and I'm stable at 4.2GHz, with Asus b450I motherboard

Quite lucky indeed.
