WHEA 19 running at 1966 FCLK and above
Some tests were done, yet not uniformly. Y cruncher, for example, regardless of configuration, my chip (early 2021 5900X) would lag significantly above 1900MHz FCLK, especially with the memory controller at that speed. The 3DMark CPU score would drop to around 1966MHz FCLK, particularly if I pushed the 1.8V rail beyond safe limits—but not higher. I’d avoid this outside competitive testing; it’s just too costly and unlikely to make a difference.
Same here. Just know with this, it can be a chance to learn and improve your own FCLK/RAM tweaking skills. You'll fail far more than you'll succeed in achieving stable settings along the way (Of course) BUT once you get it all figured it, it's a snap vs how it was before. I can vouch for that and TBH I've got alot to learn yet myself about it. I can get my DDR cranking at 600+ sometimes since TCCD is capable of way more than DDR450 speeds..... Like I did earlier this year with a Super PI run. The limitation spelled out was most likely with BH5 ran with a Socket A but even those would normally hit at least DDR460 without issue in the right boards. Now - With a VIA/SiS chipset I can see how that wasn't going to happen. I guess I'm glad I always ran NF2 boards, those rarely gave me problems getting there as long as the CPU was capable itself.
It's frustrating, but VDDG isn't working properly on the AGESA version I'm using. The only stable BIOS that supports my CPU on GIGABYTE boards is this one, and newer versions are still causing the same problem. I'll have to wait for AMD to release an update.
You're asking about the board and RAM specifications. If you're aiming for over 5000, it should help reduce sync clock performance issues.
I can handle FCLK at 1966MHz without losing speed, and actually see a boost. It only gives me about 3 WHEAs each minute with that setup.
