Nothing that could not be written off as benchmark variance.

Huge diff with 3200 divider vs 120 ref clock and 2667 divider though.

I have spent tons of time on this...

I also...am not a review site promoting a product.

No one is going to run 16-16-16 SR @ 2667 in the real world...

I understand that you are not promoting product. You are the only one with an English language review looking into the WHY the gaming performance was lacking. That lack of the "Why?" has been my major gripe with the media about Ryzen. Even now, for the most part, they don't seem to get it and certainly have not picked up on your discovery.

 

I have been working through it and I don't even have a Ryzen to experiment on at the moment. I want one if this performance issue is resolved or worked around, as at the moment, the performance in that area is about the same as my i7-2600. I have been working through this doing it all on observation and thought experiment. It would seem that Overclock.net people are skewing my observations at 3dmark.

 

Is the performance difference with the 2933 divider somewhere in between the 100 and 120 ref clk settings?

Strap = memory divider used.

1866,2133,2400,2666,2933,3200

"

I have not really spent much time on it (2933) but it seems that strap is rather slow. The jump to 3200 is pretty significant.

The jump from 2666 to 2933 appears to be able to be offset with better timings @ 2666.

Its quite possible the 2933 strap has a performance hole.

There are quite a few memory holes.

3400 in some 32m pi which i use specifically to gauge memory performance as it very sensitive and shows things aida cant see...

Anyway 3400 was faster than 3420...it like i fell into a performance hole. Lost 2s with faster speed.

Btw dual rank by nature is faster than single rank. Was same on ddr 3...d9 was like the #1 choice (sr) than elpida hyper hit...(Dr) almost same timings...faster performance.

Assuming that you have a motherboard that will allow you to change the refclk. I dont think that b350 boards have that feature though.

 

You can set the 3200Mhz memory kit that you have to be 2666Mhz in the bios, reduce the CPU multiplier from 40 to 33 for a 4GHZ OC and then adjust the refclk to 120Mhz.

 

The memory still runs at 3200Mhz and tyhe CPU still runs at 4Ghz but it improves the memory timings. The strap is that 2666 memory setting that you adjusted in the bios

Ah ok, ive been out of the game for so long im still shaking the rust off. lol Ran some firestrike and timespy numbers. 11915 in fire strike on the R5 1600 stock clocks, with my RX 480 4gb oc'ed to 1375mhz and 2000 on the ram. Timespy came in at 4455.

But when it successfully boots (2/3 of the time) everything seems to run fine.

I thought it was maybe a stability issue since my CPU is overclocked ( 1700X at3.9GHz and 1.35V). I ran a stability test on AIDA64 overnight and there was no crash.

This issue started popping up after I installed LED strips onto my computer (plugged into the motherboard's RGB headers) but I don't see how that could cause the issue.
Any thoughts?


This exact same thing is happening with me, down to the how your screen looks. I have a 1700x at 3.9 and 1.3685 on the ASRock Taichi. AIDA64 and IBT are all passing once I have a good boot.

And this crash is only on cold boots, never on reboots.

EDIT: What is your GPU?

If and when you get into Windows 10 - look at Reliability Monitor at that date and time stamp? Are there any flags?

What about Event Viewer?

  Warning: Spoiler! (Click to show)
  Warning: Spoiler! (Click to show)

The CPU score in Time spy and the Combined score in FS are both on the low side. That is indicative of low frequency memory with loose timings.

 

Ryzen has two hurdles that it has to cross, firstly is that as a System on a chip and not a monolithic CPU like Intel, it has what AMD refers to as the Infinity Fabric, which is basically like a network that connects the two ccx modules to the Memory controller and an IO hub. The bandwidth of the infinity fabric is directly related to the installed Ram Frequency.  The other hurdle is that design tends to have quite high memory latency. The end result, if you have slow Ram with high cas timings is a system with sluggish gaming performance.

 

If you can overclock the Ram and tighten the timings those scores will improve. As I found out this morning, If and when the b350 Bios ever gets the chance to adjust the refclk, and I am not sure that it ever will, You can also increase that while dropping the cpu multiplier and memory divider and you will get even more improvements.
