Hello,
Is the buyer aware that this is a frequency that is not guaranteed?
I own the 5950X and a X570 Formula VIII and this Ram Kit 2x(4Dimms,64GB), I changed to the 5800X3D but I can still give you what I know from back then:
- The CPU 5950X has a guaranteed maximum supported frequency of 3200Mhz according to the manufacturer's page, everything above that depends on the CPU grade aka CPU lottery.
https://www.amd.com/en...that means clearly everything higher is lottery, but the community of users has found out that about 1800 FLCK works for everyone (3600Mhz).
- Mainboards like the Asus X570 Formula VIII support higher frequencies but these are all marked with (O.C) and are not guaranteed and look like this:
4 x DIMM, Max. 128GB, DDR4 4800(O.C.)/4600(O.C)/4400(O.C)/4266(O.C.)/4133(O.C.)/4000(O.C.)/3866(O.C.)/3733(O.C.)/3600(O.C.)/3466(O.C.)/3200/3000/2933/2800/2666/2400/2133 MHz Memory
https://rog.asus.com/ch-de...With RAM OC, there are several factors that determine how fast the memory can be set in one's own system
- The CPU quality (whether the FLCK supports up to 1800 or higher) I recommend to leave the FLCK in 1:1 mode because only in benchmarks minimally more "MB/s" values appear.
values appear but the system latency increases and undesirable behaviour such as micro jerks can also occur in everyday desktop use ...
- Faster is not necessarily better, with Ryzen 5000 the best results are often from 3600Mhz-3800Mhz with manual low timings in 1:1 clock the best,
try to aim for the same
- Timings: lower or lower is always best (the numbers represent specific nanosecond timings, there are primary timings and secondary timings).
most people only set the primary, but by adjusting and investing time, you can find an OC that has much better latencies.
at 3600Mhz people aim for 16-16-16-36 or similar, but very few of them succeed in doing so (memory type), so some alternatives set their values a little higher and then unfortunately have minimally more latency in the ns range.
- The memory type, Samsung B Dies, is supposed to be the best...
"Samsung is: B > E > D > S
Hynix is: AFR > MFR
Microns are a mystery AFAIK
Between Hynix and Samsung it goes
B > E > AFR > D > MFR > S"
- The voltage is very important and is forgotten by some, depending on the BIOS it is not loaded directly when loading the XMP profile or is set too "high".
should be entered manually or checked after loading the profile...
