What happens if I don't use the XMP profile that came with the RAM stick/kit?

[milesuy]

My system:

CPU: AMD Ryzen 9 5950X

Motherboard: ROG Strix X570-F Gaming

RAM: TeamGroup T-Force Vulcan TUF Gaming Alliance 32GB Kit

 

It runs at 2400MHz CL16 when the RAM speed setting is set to Auto, but it runs at 3600MHz CL24 when the RAM speed setting is set to 3600MHz.

 

What happens if I don't use the XMP profile that came with the RAM stick/kit?

• Will it cause premature wear and tear?
• Will it still last long?

 

According to the RAM Laterncy Calculator, 3600MHz CL24 and 2400MHz CL16 are similar. Is there any merit to run it at 3600MHz CL24?

yes

no, it's a bit like ram overclocking except it's a set speed (you can change it tho)

with such a high cl not really

CL24 3600MT/s ram is incredibly slow. For comparison, my 3600MT/s is CL16. You need to get a better kit of 3600MT/s ram.

This is the best way to run ram unless you are gonna overclock it directly, and tune all the timings manually.

You still get the benefit of higher bandwidth, just no advantage in terms of latency. For gaming latency is usually more important though.

 

According to CPU-Z, using XMP should get you 3600 MT/s (1800 MHz) at CL19.

There's no merit to running either when you can just enable XMP and get significantly better performance. Both 2400 CL16 and 3600 CL24 are incredibly slow by DDR4 standards. 

 

Just enable XMP and be done with it.

If I set it to Auto or use DOCP, it automatically goes to 2400MHz CL16, it does not want to go to the XMP 3596 (3600MHz CL19). I guess its because my RAM kit is not in the QVL list.

Like @Skiiwee29your ram is slow. CL 24 is kinda oof at that speed. I don't know how well sk hynix modules overclock, but I would try to aim for at least 3000mhz with the same timings you have at 2400mhz.

You also forgot to mention the earth will come to an extremely violent end as we know it and all humans within the universe will cease to exist.

The QVL list is not exhaustive, it's simply a list of kits the manufacturer has tested. Meaning RAM can still work fine when it's not on that list. If you're not on the latest BIOS, it might be worth a try updating.

 

If it still doesn't work with DOCP/XMP you can always try overclocking it manually, see how close you can get to 3600 MHz CL19.

No, that only happens when someone pairs an Intel K cpu with a B series motherboard, or the other way around.

If you enable DOCP, while you are still in the BIOS you should manually set the frequency to 3600, see if that works

I just updated to the latest BIOS, but it still won't run on the XMP-3596 profile. I guess OCing the RAM would be the only option?

I guess this is better then CL24, but its still not in the memory's XMP-3596 profile.

Send thaiphoon burner screenshot to identify ic

 

Looking at the screenshots you posted thats either hynix 8gbit cjr, jjr, or djr due to being dual rank which is prefferable due to extra performance from dual rank but need a thaiphoon burner screenshot to verify

 

Cjr and jjr will do fine for <4000 and dont seem to scale that much with voltage nor do really high freq looking around online for oc results but take that with a grain of salt due to ppl being really conservative with voltage and/or overtightening primaries

 

Djr will also do fine for <4000 but it scales decently with voltage (upto ~1.9v) and can do some ludicrous clocks (>5000) though you wont be seeing those ludicrous clocks being useful or even doable on anything other than cezzane apus

 

 

Once ic is identified ill just look online for an oc profile since theres lots of em available, you simply plug and play then do a stresstest like p95 largeffts to verify stability and you are done

 

I mean you could just set 3800 19-22-22-22-52 vdimm 1.4v vsoc 1.15v everything else auto and thatd problably just work right away but performance will be meh due to subs not being set and the timings just generally being unoptimal so its prefferable to use an oc profile

It's pretty close though, only 30 MHz below expected clocks and CL20 is at least better than CL24.

 

You can try pushing it higher manually, but might be you can't get much closer.

Kind of weird that the cas latency was set to 20 instead of 19, even with DOCP enabled... but that is a pretty big improvement. I hope the performance your system provides is satisfying

in my experience with Ryzen Memory timings, unless Gear Down mode is disabled, it doesn't allow odd CL timings.
