Question Corsair Vengeance 64GB DDR5 5200MHz shows in bios as 4800Mhz

[Danemarya]

Hi!

Does anyone have Corsair Vengeance 64GB DDR5 5200MHz CL40 Dual Channel Kit ?
How did you make it work faster?
In my case, I verified and my speed on bios is 4800mhz .
Is it safe to change DRAM frequency to 5200mhz on bios?

My set-up;
AMD Ryzen 9 7900 3.7GHz
MSI PRO B650-P WIFI
GIGABYTE GeForce RTX 4070 WINDFORCE OC 12GB GDDR6X 192-bit DLSS 3.0
Cooler CPU Deepcool AK620
SSD Crucial P3 1TB PCI Express 3.0 x4 M.2.

Everybody said that my pc should work super fast (I'm using it for video editing), but still I feel that is not working as it should.

Welcome to the forums, newcomer!

Did you enable X.M.P/AMD's E.X.P.O in BIOS?

Speaking of BIOS,
MSI PRO B650-P WIFI
What BIOS version are you on for your motherboard?

You should've looked into a dual channel DDR5-6000MHz tight latencied ram kit to get the most out of your platform, as DDR5-6000Mhz is the sweet spot for DDR5 builds(regardless of Intel or AMD).

Moved thread from Graphics Cards section to Memory section.

Hello and thank you for your answear.
Yes, EXPO is enabled in bios and frequency to 5200Mhz , and my bios version is the last version.
Unfortunately, my pc's set-up was customized by a company specialized in computers for my requirement to do video editing, but they didn't set it up for me. That's why I didn't know that this dual set kit is more suitable for intel than amd. At the moment I have to work with it and get the best out of it, but not being an expert, I'm trying to see what else I could do in this case?

When I turn on my pc now , the LED from EZ Debug Led is for one minute red the first led and orange the second led, the first two goes off, the third led turn white, the third one goes off and the last one turn green and the pc starts. Two minutes it takes to boot after modification, every time I turn on. What do you think, is this normal ? Never happened before the modification. As I was saying, I'm not an expert, I'm just a little bit good.

You can either send it back and shop for a proper kit of ram that supports amd or run it at base speed.

Sorry to disappoint, but faster RAM will probably not improve video editing appreciably on an AMD CPU. I'm running my 7950X 2 x 32GB Kingston kit at stock 4800MT/s.

Check out the blue bars in the graphs below. In DaVinci Resolve, the 5200MT/s kit ran marginally slower than the 4800MT/s kit with tighter timings.

I'd concentrate on "tightening" RAM timings at 4800MT/s, but it probably won't make much difference. If you can get 5200MT/s to work, is it really worth making Premiere Pro 1% faster?

You'd be far better off squandering huge sums of money on a faster GPU to improve video render times. Consider a 24GB RTX 5090 or better still, a 48GB RTX 6000 Ada. You might have to sell the car or mortgage the house.

I upgraded from an RTX 3060 to an RTX 4070 last Black Friday for my 7950X rig. Slight improvement on 11 hour 4K/UHD renders using the 3060. I'm just not prepared to spend $6000 on a pro GPU.

A multi-core Threadripper would speed things up.

If the system keeps memory training when XMP/EXPO/DOCP is enabled, then yes, the delay is normal in some systems.

Switch off memory overclocking. Go back to 4800MT/s. Start and shut down Windows several times. If you're lucky, boot times should get considerably faster at stock JEDEC settings.

Thanks for this complete answear. I upgraded my old sistem to this set-up , with Ryzen 9 7900 3.7GHz and GeForce RTX 4070 WINDFORCE OC 12GB , works much better than the old one but maybe it needs a little bit of setting things up. I am using premiere pro for rendering 4k and AI stuff.

Your motherboard did not like the ram settings in the bios and was working to find something that works.
Eventually, it found a suitable lower speed and allowed the boot process to continue.
The reaction to a bad set of specs is normal and good.

You might contact Corsair customer support.
Or, you can try your desired settings but increase the ram voltage a bit at a time until it works.
Check that a full pass of memtest shows NO errors.

Since you're using Premiere Pro and Puget Systems' benchmark program shows virtually no improvement at 5200MT/s, I recommend sticking with 4800MT/s.

Unlike gaming, there's no point chasing the illusory benefits of faster RAM with Premiere Pro. You'd gain far more with extra CPU cores and an RTX 5090, but at enormous cost. Stick with what you've got and be happy.

On my video editing rig, I installed three 1TB M.2 NVMe drives.
1). Windows + Adobe + Topaz software
2). Adobe + Topaz scratch disk
3). Video work-in-progress files

You'll probably benefit from adding a second M.2 NVMe drive (500GB would do, but 1TB might be faster) and configure it as an Adobe scratch disk.
https://helpx.adobe.com/premiere-elements/using/scratch-disks.html

Keeping everything on one drive is not ideal:-
a) Windows with its own page file and swap file
b) Adobe scratch files
c) Video files currently being processed

Try to separate things out. Even a SATA drive might pay dividends to hold work-in-progress files. The gain with two more SSDs might be marginal, but it's worth a try.
