Performance issues with Ryzen 1700

AMD Ryzen is known to be critical on the memory support and AMD will very soon come out with a new BIOS micro code to the motherboard vendors for them to implement, so keep an eye out here when the latest BIOS ver. is on track: http://www.gigabyte.us/Motherboard/GA-AB350-Gaming-3-rev-10#support-dl
It will then support more memory types, frequencies and timings.
Current Bios ver. F6 (AGESA 1004a) 2017/04/10

Hi guys,

Wish I could drop in and give you guys a new BIOS but I don't have them yet Latest word is they are working on a new set with AGESA 1006... I am pushing as hard as I can to get you guys something new to test as soon as its ready. Just wanted to say that we are working on it (I know that phrase gets old - trust me I am a user/gamer/enthusiast too) but me going to Dreamhack (for work not as a participant) doesn't stop the BIOS team or engineers from working on the code ;-)

Just to recap these are the issue being worked on:

*For those looking for IOMMU fixes we are hopefully going to have an option to force boot off a specific PCIe slot. Its not the grouping fix, but a work around for now.
*Disable LAN (Per request)
Disable Audio (Per request)
"ROM Image update" (Being worked on with AMI, no ETA)
Cold boot / Wont boot. Have to re-flash BIOS. (people have referred to this as "soft brick")
*AGESA 1006 - improve memory (Got high hopes for this one. Going to enable 20+ memory register)

(Edit) P-State overclocking / downclocking while overclocked.

As for the performance issue (which some of it will be addressed in future Bios codes):
AMD: New AMD Ryzen chipset drivers now available

The AMD Ryzen Balanced power plan allows your AMD Ryzen processor to more quickly raise clockspeeds. The plan also prevents your CPU cores from being "parked," an idle state that can negatively impact the performance of many (but not all) games. If you're interested in additional details, our original blog on the topic has lots more to offer.

AMD: Balanced power plan optimized for AMD Ryzen™ processors

4/26/2017 Update: The AMD Ryzen Balanced Power Plan is now included in the official AMD chipset drivers starting with version 17.10! Simply download and install the latest chipset driver package, and the new plan will be automatically configured for you. Windows 10 64-bit is required.

Perhaps this will solve some of your issues.

BUmmer . I'd personally would have bought the 1600X (or the 1800X ) , because they have the highest frequencies . And games tend to like that over a lot of cores .

Not sure if this will help but It took me some playing with the 1700 to get it to run properly:
Some things to note: running Win7 Pro, 32 GB ram dual rank TridenZ 3200MHz 14-14-14-34, Gigabyte gaming 5 X370.

1. I OC to 3.7 GHz. My cinebench tests were done at 3.0, 3.4, 3.5, 3.6 and 3.7 GHz.
at 3.6 GHz I saw a decline from 3.5GHz, the rest of the scores were in line with what people report online, with 1633 at 3.7 GHz.

2. I OCed the ram to 2667 MHz.
Between the ram oced and the CPU oc, my FPS increased in heaven bechmark in full HD from 126 to 145 fps. In games the variance was not always consistent, but it was there in all games I tested (Tomb raider 2013, Path of Exile, Stalker Lost Alpha, Crysis 1).

3. I noted that before the overclocks I would get most of my stutter (under 30 FPS even if the benchmark was reporting high fps) when a CPU core would begin or stop turbo boosting. Once 3.7 GHz was set as default, the stutter was only perceptible in very specific moments of the benchmarks (2 moments) that I would attribute to lack of optimization for the benchmark itself (the heaven bechmark that is).
I honestly believe that because if you get the same stutter in the same exact spot always, the CPU can cope with everything except a specific command it is getting at that point.

Running a 1080 on water my results in most cases are similar to a 7700k but there are games where my CPU falls significantly behind even with the overclock.
Lucky for me, the FPS is still high enough not to be noticeable.

4. There is a severe lack of monitoring software for Ryzen CPUs. This makes overclocking a bit more risky. My automatic overclocking was giving me very strange readings on the VSOC. For people who want to be on the safe side Id advice NOT to overclock any ryzen 7 CPU until the monitoring software is accurate.

5. If you are going to use this with Win7, understand that you will run into problems in both installation and updates for windows. I managed to fix all my problems (so far), but I do not recommend it for people who dont have a decent amount of patience and are willing to take a decent amount of time learning about OS compatibility.
The two main problems I run into were: USB not working (fixed by installing manually a usb driver from DVD using PS/2) and updating all windows critical security, especially Microsoft Framework 4.6.2. Other way I would get Windows 7 no loading properly in some case at start. It seems any drivers that are WIN10 only can cause this issue and some manufacturers do not even tell you about it in their drivers (in my case Lan Killer Driver for WIN7 64 Bit was actually a WIN10 driver).

This is still a relatively new architecture so some problems are expected to appear. However, so far the performance for streaming on the same PC is quite impressive. No matter what I stream, I drop no frames.
I made a stress test to see how it can cope:
Prime 95 + Heaven benchmark + Skype call with screen share + 3 games in the background and 7 Chrome youtube videos.
The screen share was a bit choppy as my friend noted (I did not notice it) and ocne I turned off prime95 he said it was 100% smooth.

That is not perfect ofc, but for the price of the 1700... I am quite impressed.

I'm Impressed! You have indeed made a good work sir/mam
Kudos.

What I also read just in previous weeks is that AMD released newer AGESA microcode to the mobo manufacturers, which vill later come out as a new BIOS update from them. So check the mobo manufactory support pages for ev. BIOS update in near future.
