Bandwidth of DDR4 memory
Bandwidth of DDR4 memory
The configuration is already known to be struggling with performance. I understand the concern about memory speed and its impact. The test results indicate a bandwidth of 17.3 GB/s, which may not be ideal. It seems the issue lies in the memory type rather than the speed itself. I’ve noted the Samsung C die and the PSU limitations.
Memtest 86 isn't suitable for benchmarking; it mainly checks stability. Consider using AIDA64 for more accurate results. For instance, the memory controller on Zen+ CPUs can be problematic—your bench showed stability up to 3466MHz but not at 3600MHz with XMP enabled. The fix would be to upgrade to a CPU with a better memory controller, such as Zen 3 models.
Yep. I have them in cart already lol. I am about 4 months away from away from Ryzen 9, Asus X570 Crosshair, XFX Speedster 6800xt. I have not gotten into OC'ing since early AM3 socket and an old intel 754 i believe? In between the time i get the new system i thought I would try to learn the new methods and approaches to OC nowadays. So AIDA64 fot a bandwidth test? I am happy to see 0 errors 3 hours in with 4 sticks at 3000Mhz. If I can maintain cooling on the RAM and get no errors I will try to go for 3200 Mhz. I appreciate the advice! Nice to get tips and not jeers for the setup lol. Not to spin off topic but while i let memtest run and then AIDA I need to figure out the sweet spot and how to best go about OC'ing for my GPU. Thinking about re pasting the chips but I haven't taken a GPU apart in years. It's an XFX Rx 570 and it hurts to say it but 4GB edition. As i said just trying to play around now before I break an expensive system!
DDR4 requires no extra cooling at these speeds. The main constraint is the CPU memory controller, not your RAM. Removing two memory sticks can reduce stress on the controller, allowing you to achieve higher RAM speeds. This would resolve the problem and enable using the 3600MHz XMP profile I previously overclocked my 2600 with a solid static boost of 4.1GHz. Higher clocks are possible with Precision Boost Override, though most chips struggle to reach 4.1GHz or above without proper cooling.
