Ryzen Overclock thread. JUST OC results, and hardware/settings

What PSU's people are using would be useful info.

EVGA 750W P2

I have a 650W Corsair power supply. It's completely modular, so perhaps the H series? I'm at work and don't rightly remember. It's now 7 years-old.

Here are the settings i've settled on for now:

4GHz 0.0625v offset
2666 14-16-16-34 14 wr 1.25v
boost disabled
everything else pretty much at auto/normal

My real goal was to get the mem to 2800 or higher to get the infinity fabric up to speed, but ohh well.
Running my threaded memory access benchmark I can see as high as 20% performance hit when using more threads than a single CCX has (got the idea to look into this from the builder's thread).

4.1GHz and 4.2GHz will post, but I didn't bother trying to stability testing them.

If you are running 4x16GB @ 2666 at those timings, I bet your RAM performance is comparable to 2x8GB single-rank 3200 because of dual-rank all DIMMs populated. So that's actually very good considering you are at 64GB.

Doesn't ECC run slower too? Or is it just that they don't sell O/C'd dimms?

 

[DrMrLordX]

ECC will run with looser timings.

Doesn't seem like I won the lottery this time.

1700 @3.6Ghz 1.27v
ASUS CH6
G-Skill(F4-3200C14D-16GTZKW)2933 14-14-14-34 1.35v

Couldn't pass IBT at 1.26v. I'll push for 3.8 when I get a better cooler.

 

[EXCellR8]

current:

1700 @ 3.8ghz 1.33v
X370 Pro gaming
G.Skill Flare X @ 2667 14-14-14-34 1T

haven't tried 4.0 on this board but it does have better VRM so I suppose it's possible. my cooling system can definitely handle it.

 

[EXCellR8]

well, my goal with this chip was meeting 1700cb in Cinebench...

NAILED IT!

AIDA64 CPUID

3.9ghz seems just as stable as 3.8 but it also seems to be the cutoff point for most adopters.

Corsair 650w RMi, no coil whine and the fan hardly comes on, only time ive seen the fan spin was running prime and furmark at the same time.

Seasonic X750, same PSU I used with the FX 8350

Turn up the fan speed. Temps matter when it comes to what volts you need for a certain clock.

I need 1.275 v for 3.7 GHz at 60 C where as only 1.225 at 50 C

 

[guskline]

My EK D5Vario 140 pump failed. It was a used unit. Fortunately I have a Swiftech MCP35x pump reservoir combo as a backup, Ordered a new D5 pump.

 

[EXCellR8]

I was able to manage a stable 4.0ghz but I had to crank the voltage to 1.45! temps reached 65c full load but that's a bit too crispy for my liking.

both load lines @ level 2

it also only netted me an extra 40 points in cinebench... meh.

 

[guskline]

EXCellR8, you are pushing that 1700 pretty hard. May want to pull back just a bit and give it some breathing room.

 

[EXCellR8]

4ghz isn't my long-term, that's for sure, just kind of wanted to see what I could get away with heh heh

3.8 to 3.9ghz is plenty for my needs

 

[guskline]

Smart move EXCellR8

 

[Crono]

Using a Cougar CMX1000 with 1700X and a Enermax Triathlor 800W with the 1600. Both running at 3.9GHz right now.

Thanks for the tip!

I'll play around with the setup on the weekend. I should have an aftermarket cooler by then.

1600 @ 3.85ghz 1.35v
X370 Killer Sli/ac
Corsair Vengeance 3200 @ 2933 16-18-18-36 1T

This is as far as I can get with the Wraith Spire. I got a AM4 mounting bracket coming from Taiwan for my Thermalright True Spirit 120. I think the Spire is doing a pretty good job for a stock cooler. It will be interesting to see how much better the True Spirit does if at all. I also have everything for water cooling except the water block. I don't think there is an AM4 kit for my Apogee GT. Regardless I'm not sure if it's worth the hassle of setting up a loop for another 50 to 150mhz.

.

What were your load temps like?

My 1600 hits 3.8g at 1.3375 with a temp of 52 C. Did not try fractional multipliers. But yes, it does not seem worth pushing insane amounts of volts and money on WC for 150 mhz

 

[bfun_x1]

Temps are about 38 idle and 69 in Prime95. I'm pretty sure I can go lower on the voltage but I haven't had time to test yet as I've mostly been trying to find the maximum speed. Temps in general have been all over the place. My idle temp rises to about 56 in the bios but then drops down to the 30s when when Windows starts. My fan curve seems to work correctly in the bios but then seems to lag behind the curve in Windows. The system also shuts down when temps reach 75 and if I put the voltage over 4.1 the CPU gets locked at about 3.2ghz. And like many others I can't reach 3200 on my memory. I'm hopping these are all bios issues that will get patched.

So here's a odd one. I decided to get a set of the much vaunted "samsung b die" DDR4 and see what the difference was. I picked up a kit of Team Dark Pro 3200Mhz DDR4 14-14-14-31 memory to tinker about with. Much to my surprise it booted right up first try on "auto" settings in the BIOS at it's rated speed and 14-14-14-31 timings at 3200Mhz. That's not the odd part however, the odd thing is now I'm able to achieve a 4Ghz stable overclock at much less voltage than I needed with my Geil Evo 3200Mhz kit. I was previously only able to run 4Ghz stable with 1.35v any lower would cause errors and system hangs under stress tests. Now though I'm able to run stable 4Ghz with 1.3125v set in BIOS. Been running AIDA64 stress test now for about 3 hours and no issues or hangs at all. This has me left with no answers as to why I'm now able to achieve a stable overclock with less CPU voltage while only having changed RAM?

 

[unseenmorbidity]

4Ghz with 1.3125v

That seems insane.... Are you sure it's actually stable?

I'm closing in on 4 hours running AIDA64 stress test, so far so good.
