yeah double post.

so, i just went up... 4.00ghz to 4.025ghz. same voltage. errored out in daz3d iray cpu rendering.

The Silicon Lottery released their binned Ryzen CPUs today and included the following statistics in their product pages. This gives us more of an idea on the differences among the lineup in terms of overclocking potential and should help us set our expectations. AMD has clearly squeezed as many MHz out of their CPUs as the process allows.

Ryzen 7 1700
93% reach 3.8GHz @ 1.376V
70% reach 3.9GHz @ 1.408V
20% reach 4.0GHz @ 1.440V

Ryzen 7 1700X
100% reach 3.8GHz @ 1.360V
77% reach 3.9GHz @ 1.392V
33% reach 4.0GHz @ 1.424V

Ryzen 7 1800X
100% reach 3.8GHz (assumed)
97% reach 3.9GHz @ 1.376V
67% reach 4.0GHz @ 1.408V
20% reach 4.1GHz @ 1.440V

Note:
Their test setup used the Realbench stress test for 1 hour on an Asus Crosshair VI, cooled by a Corsair H105 with 2 X 8GB of 2400MHz CL15 RAM.

I had my 1700 set the same, until I ran IntelBurnTest on maximum. I had to go up to 1.274v all is good now.

Also, if you could be getting big vdroop causing your vcore to drop way below what you set, but you probably already knew that.
ASUS board? The Crosshair AM3+ board has a reputation for underreporting voltages.

I guess this is good marketing. "With the ASUS you can get a much better overclock! Look at the low voltages the reviewers got when compared with those other boards!"

Of course, it's not like other board makers can't try to copy the same scheme. The Crosshair is hardly a recent board. If any maker gets exposed all they have to do is say it was a BIOS bug.

i like AIOs cuz of the lack of maintenance compared to a loop. its all one thing. it follows the same laws of physics that a normal rad follows. more fins bigger etc more heat soaked...

Have you seen internals of one after a year or so of use?

I dont know how much they have improved but i cant imagine much.

They are fairly disposable.

At min id try to score a used h220x vs those sealed units.

My boards not crosshair but it is asus..

On the contrary it was quite the opposite.

It over reported.

Air cooling fo life. Cooler VRM's, never have to worry about anything, cheaper. quieter. Only thing AIO's going for them is lower CPU temps and aesthetics, but there are good looking towers like be quiet dark rock 3 smile.gif

Oh I totally agree. Chew

Anyway. 4.025ghz.
1.375v not stable
1.400v not stable
1.425v testing right now (not stable)

That's what I set as the pstate voltages

Now the ASRock a-tuner software says 1.425 is actually around 1.48v when I put load on the CPU.

The VRMs are approaching 100c too. My little thermal gun thing is saying that the VRMs on the left side of the CPU are doing the heavy lifting with the top most one hitting 70c but as I go down the temps drop off quickly. Maybe a VRM load balancing issue? The ones on top don't do anything really it seems.

Core VRM
SOC VRM

Best to identify which one is for the cores and which ones are for the SOC.

SOC doesn't seem to consume much thus running cooler.
post #6099 of 11511
Yah I'd like to know what's what and where



And why
post #6100 of 11511
On my K7, the SOC is on the top. 4-phases.
Core with 6-phases is near the IO.

From hammerring them with different loads, 55-60C depending on airflow.
