Corsair Vengeance 32GB DDR5-6000 CL36 + Maxsun B650

[mateusmms]

Hi guys, can anyone who understands timing help me?

I bought the Corsair Vengeance 32GB DDR5-6000 CL36 kit

I managed to get it to stay at 6400Mhz with CL 34 as per the photos, how can I improve?

I tried following the guide https://www.overclockers.com/corsair-vengeance-32gb-ddr5-6000-cl36-memory-kit-review/

but not the image. I need to remove the bios battery

Thanks!

I see in the review that the DRAM Voltage was set to 1.45v to achieve the overclock. Your RAM voltage appears to be 1.35v (XMP Default).

DDR5-6400 CL32-36-36-36 1.45V​

On our test platform, we could reach the DDR5-6400 at tight timings. The required voltage was 1.45V, which isn’t a problem for daily work without additional airflow.

Yes you are correct. I followed all the measurements including voltage 1.45, but there was no video. Maybe Maxsun B650 don't accept :/

It's not guaranteed that 6400 1:1 will work on these CPUs. If you can make 6400 CL34 and it's stable then it's already not bad. I highly doubt that Maxsun has good BIOS team that tweaks everything, so I would be happy if it works at 6400 at all. Don't mean me wrong, some more popular brands like Biostar have problems with even that.
On the other hand, it doesn't matter much if RAM works at 6000, 6200, or 6400 on these CPUs. The bandwidth and latency are almost the same. The difference is mainly on higher chips, but it's also nothing special. I would check if 6200 CL28/30 works at 1.45V. Something like 28/30-37-37 or 28/30-38-38. Set tREFI to the max and check if it works (typically around 32k or 64k, depending on the motherboard and other things).

Hi my friend, should I try something like that?

I haven't tested it yet, because if I make a mistake there will be no video and it's a lot of work to remove the video card, remove the Bios battery and then try to turn it on until it resets.

Doesn't the motherboard have a bios reset pin set? Refer to the owner's manual. It'll be easier this method than removing the video card.

I said 28 or 30, so it will be more like 28-38-38-58-88 (the "primary timing parameters") or 30-38-38-58-88 (the last two can be different, but should work like that).
The memory kit should work like that. It's hard to say if the motherboard will.

Also, as Nebulous said, there should be a reset CMOS jumper somewhere. Check the motherboard's manual.
