Adjusting Ryzen performance issues and memory problems
Gigabyte B350 Gaming 3, rev 1.0
Corsair CMK8GX4M2B3200C16R Vengeance LPX 8 GB (2x4 GB) DDR4 3200 MHz
Amd Ryzen 1600X
Noctua D15 AM4 Edition
The best overclocked I've achieved is 4.0Ghz Stable, 1.38-1.392V, Soc 1.1V - 71C
I used the XMP profile and still experienced constant BSODs
even when manually setting timings
the RAM chip shows four sets of numbers, 16, 18, 18, 36 1.35V, rather than five series so I’m curious about why
since overclocking requires entering five series of numbers to the RAM
what’s the correct procedure?
Do you know anyone with similar hardware who has encountered this issue or has a solution?
Good stuff
Getting there is great. Good results. Please close this thread as it’s becoming a bit long. Let me know via PM how you’re doing, and I’ll be happy to assist with any questions.
I own a set of RAM with a 3000MHz rating on an ASRock AB350 Pro 4 board that supports running up to 2800MHz and 2933MHz. It performs stably, though after several reboots the BIOS tends to reset. Most of it is tuned for Intel memory controllers, so you're unlikely to reach its full rated speed.
yeah, I'd agree with Simon a little. The ram isn't on the QVL for the mobo, meaning there's no guarantee it will work at it's rated speed. Apart from trying to set XMP profiles or manually setting timings as you've done, if it doesn't go higher that 2866mhz there's very little you can do. You can up the voltage a notch, and loosen the timings further from where they are to see if you can hit the 3200mhz. The only downside being that, as you loosen the timings for functionality, you loose the benefits of faster ram. Because fast ram doesn't always make up for the benefits of tighter timings (which increases bandwidth) so there's a bit of a trade off there.
You could try sell you existing ram to offset the cost of buying a matched set of DIMMS on the QVL for your mobo.
Keep in mind though at 2866mhz your not that badly off. After 2966mhz the benefits of faster ram drop off at higher speeds. The biggest improvement in performance is between 2400 and 2966,
okay thanks Keith, if that is the case I might hold onto this ram an buy some of that Sweet Samsung B-DIE recommended ram at a later date, what speeds have you guys reached with CPU
Here’s the rewritten version:
The situation seems clear, so I might keep this RAM and purchase some of that recommended Sweet Samsung B-DIE later. I don’t know the speeds you’ve achieved with your CPU yet.
That’s a good idea overall. Just one thing to keep in mind is what you’ll need if you upgrade your RAM in the future. Right now, 16GB is considered the norm for AAA games at Ultra 1080p. Titles like BF1, Wolfenstein 2, Destiny 2, and many new releases have already surpassed 8GB. Eighteen gigabytes was once ideal, but now it’s 16GB for gaming. So when you decide to replace your RAM, aim for two 8GB modules that match each other. Avoid adding another 8GB just in case, as this could cause compatibility problems with the modules.
I’m currently at 3.9 on my CPU. I feel fortunate—I have a stable vcore of 1.3, and it passed Prime testing last night. Under stress temperatures between 73-77°C, I’m getting around 77°C, but I haven’t changed any fan settings. With low voltages and good temps, I believe I can reach 4GHz. Ryzen’s maximum is about 4/4.1 at air speed, and the extra 100/200MHz won’t make much difference except a few points on a synthetic test. That’s why I’m satisfied.
Even with stock settings, my 1600x still performs well, delivering solid results. At 3.9, I see a few more FPS and better benchmarks.
Also, I’m not sure if this upgrade helped much, but I did overclock the CPU first. I ran extensive tests using Prime95 small ffts, Memtest (on stock), and other stress tools to confirm stability and performance gains.
OC'ing my RAM was another challenge. I used a basic Crucial generic 2400 module (2 x 8GB). I didn’t expect much overhead from overclocking. Then I upgraded the memory strap to 2666 without increasing voltage, and ran Memtest for 8 hours—passing three cycles without errors. So I’m also happy with that. I think I have a bit more room and will try another upgrade soon.
As for your question, what’s your maximum overclock voltage? For example, if your CPU clock tops out at 1.35V, then 1.38/1.39 is fine. It’s sufficient for continuous use. If you were running at 3.8GHz at 1.35V, that would be the recommended setting for a daily system. Still, if your maximum temperature stays under 71°C with Small FFTs, 1.38/1.39 is sustainable.
This article provides a helpful overview of Ryzen overclocking. There might be some details you haven't reviewed that could be useful: http://www.overclockers.com/amd-ryzen-ov...ing-guide/. I think you're aware that overclocking generally relies on trial and error. Another aspect worth thinking about is the LLC setting. I haven't adjusted it yet, but I plan to do so. Currently it's set to level one, which appears to be the standard for OC settings up to 3.9. If you're already running at 4GHz, increasing the LLC to level 2 (or the appropriate value for your motherboard) could improve stability. This adjustment helps prevent voltage droop and can support higher core voltages with strong clocks. It's recommended to experiment, but avoid going beyond L3 unless you're aiming for extreme overclocking.
You're mistaken, I'm still a beginner and haven't adjusted anything yet. I'm trying to understand what I can do with this clock speed tonight—planning to lower it slightly, around 1.37V, and run a small FFT test before bed. The load line calibration doesn't seem to have the effect I expected, even though I think setting the SoC Voltage to 1.1V is working similarly. My voltage readings are quite inconsistent, fluctuating between 1.38V and 1.392V.
lenqq :
you're wrong I'm a complete novice, I've yet to tweak to see what I can achieve this clock speed at I plan to take it down a few notches tonight perhaps 1.37V an run a small FFT test while I go to bed, the load line calibration I can't seem to find a setting for my motherboard, though I believe setting SoC Voltage to 1.1V is having the same effect?! my voltage is very jumpy an goes from 1.38V to 1.392
Well, for me at least when OC'ing, my objective is to have the highest clockspeed with lowest stable voltage and lowest temps.
ah I see. Well, If i can be of help, just PM me. LLC is there somewhere, it may be called something else, although I'm sure it's not SOC. That voltage (SOC) shouldn't go above 1.1, so if you can back it to 1.05 which is better.
Ill see if I can match my settings (vcore voltages etc) with the names/versions on your mobo, and give you some setting to dial in and test. Keep in mind what works for me, may not work for you. But the point being you'll get an idea of what to change, and where to start. OC'ing is great fun, but measure and record as you go, so you have something to refer to for a baseline.
Anyway, enjoy your evening (it's evening here), and PM if you have any questions.
There is no loadline calibration control for this motherboard either. This appears to be a typical issue with lower-end AM4 models using the B350 chipset, as seen in ASRock’s Fatal1ty AB350 Gaming K4. On the other hand, MSI provides a usable set of loadline calibration options that assist overclockers in fine-tuning the voltage curve. The CPU frequency multiplier is offered with 0.25x granularity, and core disabling is also available for those who enjoy experimenting.
