New Build! Looking to perform some overclocking!
I’m still figuring out the best way to go before assembling everything. What’s the feasibility of overclocking this build? Remember, the GTX 1080 is only available temporarily until I might get a 2080TI. Should the 650W power supply be sufficient for it? PCPartPicker suggests the actual draw is around 470W. Any advice or thoughts on what you see here would be really helpful! Thanks!
On a Ryzen, the 3600/16 has a slight edge over the 3200/14. On an Intel platform, memory usage differs significantly, making the difference negligible. In the past, 1866/10 was faster than 1600/9, but the Dominators at 1600/7 were even quicker, with Cas being the main reason for the delay. Nowadays, Cas plays a smaller role as CPUs have become so fast that benchmarks are needed to detect any differences. SSDs have reduced its importance, and exact time measurements aren't tracked. With Amd and Infinity Fabric, speed of RAM becomes more crucial than Cas, since it determines communication rates. 3200/14 was significant because it represented Samsung B-die, offering the best stability and compatibility.
PSU is sufficient for what I need.
Instructions for boosting your system's performance:
First, turn on PBO. You might be able to use the RAM you currently have at 3600mhz cl16, but it would work fine.
What would happen if you upgrade your system video card to 2080TI while keeping the 650W power?
Why is the 3600MHz RAM recommended?
I selected 3200MHz for lower timing CL14 based on a chart.
If I increased it to 3600MHz, I’d need CL14 to stay in line with the requirements.
Ah that’s interesting
I’m using this table to choose ram
https://drive.google.com/file/d/0B5ePJLH...ZMYzg/view
Unless I find 3600 at 14CL I’d rather keep the 3200 14CL if I can. I’ll certainly try your recommendation.
If something goes wrong over locking the ram like that, would I know right away? Or could it take a few months before it shows up
Heh, this table applies only to Intel chips. Ryzen relies on Infinity Fabric for communication between chiplets and cores. This configuration depends on the RAM speed. Cores running at 3200MHz will exchange data at 1600MHz. At 3600MHz, they communicate at 1800MHz. It’s like sacrificing about 1% performance in timing but gaining a 3% improvement in communication speed.
This explains why many people are talking about Ryzen’s faster RAM. However, there are limitations—specifically with the 2k series, the input frequency was capped at 3466MHz. Beyond that, the ratio shifted from 1:1 to 2:1, so 3600MHz dropped to 900MHz communication, while 3200MHz stayed optimal at 1600MHz. With the 3k series, the cap increased to 3733MHz, making 3600MHz ideal again.
You could bypass this by manually adjusting the IF settings, but unless you’re confident with fclock, uclock, and mclock adjustments, and the BIOS supports it, I wouldn’t recommend it.
So this table applies only to Intel CPUs. I tried my best to grasp what you meant. I think 3600 is the optimal setting with a 3k and when you mention 3k, you're referring to the 3900x? since that's likely the 3k generation? (this is my first time hearing that term, it's the first AMD build).
I'll skip the manual adjustments like you suggested. I'd like stable performance and aim for overclocking. Should I increase to 3600? Does CL matter with AMD? In your opinion, which option is better?
-3200 CL 14
or
-3600 CL 16
or
the third option I'm not sure about but would appreciate your advice
I understand the 1:1 to 2:1 ratio and I'd prefer to keep it at 1:1 as well. Also, I'm looking for something between $300 and $450, and 450 is a bit extreme with the Ryzen 3900x.
Thanks a lot for your assistance! I really value your help!
On a Ryzen, the 3600/16 offers a slight edge over the 3200/14. On an Intel platform, memory usage differs significantly, making the difference negligible. In the past, 1866/10 was faster than 1600/9, but the Dominators at 1600/7 were even quicker, with Cas being the main limiting factor. Nowadays, CPUs are so fast that any distinction becomes hard to notice, except through benchmarks or calculators. SSDs have reduced the importance of this gap, as partial seconds no longer matter.
With Amd and Infinity Fabric, performance hinges more on RAM speed than on the CPU itself, since RAM dictates communication rates. 3200/14 was crucial because it represented Samsung B-die, offering stability, compatibility, and near-XMP speeds with minimal trouble. 3200/16 supported A or D/E/Z-die options from various manufacturers, but often led to incompatibility issues, boot failures, or stuck at 2133 or rarely exceeding 2933MHz.
Agesa largely resolved these challenges over time. Today, the difference is minimal, except in cases where overclocking or highly RAM-sensitive software yields better results. For gaming, it usually doesn’t matter much.
I appreciate your feedback. I plan to use this information wisely.
I checked Memory Express and looked for products in Winnipeg.
I found the Ripjaws V Series 32GB DDR4 3600MHz CL16 Dual Channel Kit (2 x 16GB), the Trident Z NEO Series 32GB DDR4 3600MHz CL16 Dual Channel Kit (2x 16GB) and a 64GB version.
I’m considering switching from 16GB to higher capacities since I need more multitasking and browser tabs.
Based on what you said, CL speed isn’t a big issue for me, so all three options seem acceptable—CL16 or CL18.
Are there any brands I should skip or should I prioritize getting?
The memory upgrade is my main concern, and I’m finished with the search!
Thanks!
