Limit on memory data transfer rates for B450 motherboards
Limit on memory data transfer rates for B450 motherboards
This journey became smoother on an x470 board like the Asus TUF X470 PLUS GAMING, possibly because it exceeded 3200. The reason might lie in a combination of factors—luck, the quality of materials, tuning with precise timings and BIOS settings, or even a bit of luck with pickles.
For a 2700X configuration such as a B450 or X470 would be perfect. With a 3700X, an X570 seems more suitable since these models tend to complement each other. The higher-end option usually requires higher memory frequency, especially with premium modules. If the module supports voltage scaling up to around 1.45V, that’s quite manageable depending on the model. When it comes to voltage, we refer to frequency scaling. Certain chips can reach XMP levels as high as 1.45V, though this varies by manufacturer. Most importantly, the PCB layout plays a role—short traces on A2 boards work well. The memory controller is crucial; AMD often includes Gear Down to avoid latency issues. While most CPUs support up to 3600MHz XMP, some AMD systems have limitations with Cas 19 XMP. My B450-I handles B-Die memory smoothly and can reach 3600MHz without needing extreme adjustments. Sometimes you need to gradually increase the frequency from a lower base, possibly over several hours or even days, depending on the setup. Stability testing varies greatly—some users accept minor delays for performance gains, while others demand consistent stability for gaming or high-end work. Everyone has their ideal threshold for what feels stable. It’s hard to give a universal answer, but it’s clear there are many factors involved.
The challenge lies in pushing the RAM beyond its standard 3200 MHz limit. The board supports DDR4 3200, but overclocking beyond that requires careful tuning or a different module. The exact cause for success depends on stability factors like voltage settings, power quality, and thermal conditions. Another identical RAM might fail to OC past 3200 due to manufacturing variations, improper installation, or insufficient cooling.
It's more likely that memory and make will be very similar. A small difference like 33MHz won't noticeably affect performance; you'd still see the slower stick running. Binning helps here. You can test each stick separately to assess its capabilities. Among 50 RAM sticks, you'd identify the best performers. The exact impact varies because everyone's setup is unique. This applies to processors and memory too. Most people overlook minor differences like 33 or 66MHz. I recently overclocked a 3000MHz CPU stick, but it didn't impress much. https://warp9-systems.proboards.com/thre...mhz-module On the other hand, 3600MHz sticks will approach around 4000MHz.
Imagine you're evaluating the reliability of this specific RAM under certain conditions. The situation involves comparing two sources: the PCPP listing and the manufacturer's official site. You're curious about the likelihood of these RAM sticks exceeding their rated speed to DDR4 3600 on the Gigabyte board, despite the advertised 3200 MHz limit. You're also interested in how many sets would stay within the 3200 MHz range if you tested fifty identical units. Additionally, you want insight into why some sticks might not reach or exceed that speed. This involves analyzing consistency, potential manufacturing variations, and possible causes for performance deviations.
Your asking questions that would take testing done on 50 sticks of Vulcan Z and record the data and compare it for the answers you seek. I cannot provide any more information than that of which I base my own experience on. One of them is not testing 50 sticks of memory. I have 4 sets of DDR4 memory that I've ever done any tweaking with. Any how, we are talking about frequencies I don't even think to run while I'm much past that. Performance comes with sheer raw memory speed first and foremost. So 3200mhz is a nice boost over 2133, while 4000mhz is a nice boost over 3200mhz. At best, looking at pushing 3000mhz sticks to 3466mhz at a high voltage 1.5-1.60v, I had used 1.60v at this frequency. Just to see how far they'd go. I manually adjusted primary timing set. I did not bother with sub timings while the memory just didn't scale well at all. One more thing about the memory. Even testing 50 sticks on X Cpu and Mobo, does not mean they will do the same on a different Cpu and mobo. Again, there's a lot of variables. ---- What would make this ram not clock as well as another. Well the overclock difference tends to be minor in most cases. As I had said before, 33mhz to most people isn't a worth while attempt. My g.Skill 4277mhz sticks to 4300mhz. It's an entire 33mhz extra clock, but have no need to change anything. Can't even tell the difference. Just looks cool. So you overclocked 3200 to 3400mhz. It's 100mhz effective overclock. It's not a big leap as the DDR2 numbers are deceiving. It's actually 3200 MT/s = 1600 Mhz . So there's not a big leap like oh it's 200 mhz. That's not the case. You only went from 1500mhz to 1600mhz there. That's the actual clock frequency, while MT/s stands for Millions of Transfers per second. So 3200 Million transfers per second PEAK not necessarily sustainable. That's why the AIDA64 memory badnwidth test is so quick.... well all their tests are quick actually. I don't find it to be a super accurate testing procedure while it measure a peak performance over a sustained performance. But it's still good for comparisons because the results are accurate (or within margin of error), on the same system and other like systems. What makes one memory stick differ from another is voltage scaling. I believe I touched on this. So to help perspective..... You see people under-volting the Cpu for better temps right. Some people can run a lower voltage than others, down to the 0.0010v difference. It's measurable. Well memory is the same way. That's how electronics are binned. Chip A will do 2000mhz Cas 19 1.3750v Chip B will do 2000mhz Cas 19 but this one does it at 1.360v which one is your better ram stick then? It's pretty much that simple. Timings further complicate this. Tighter the timing, the more voltage required for stability. There is a threshold. So when people buy Ram, and the XMP profile says 1.35v for 3000mhz..... and for maybe 20 bucks more, they see the 3600mhz at 1.35v..... which memory should you buy? Irregardless if the Cpu and Motherboard will even run it's XMP rated speeds? edit: Buy the memory with Even timings 16-18-18 for example at the highest frequency possible 3600mhz 1.35v. That is all
You're facing a decision with limited funds. You already own most components, so only your GPU and RAM matter. With $290 left, you must choose between two options: a GTX 1660 for $205 and DDR4 3600 RAM at $85, or a GTX 1660 Super for $225 and DDR4 3200 RAM at $65. Pick the one that fits your needs best to boost performance.
