Hi All

Any idea what could be the problem ?

I purchased 2 x Corsair vengeance 16gb 3600mhz kits (2x8gb modules per kit) but when i enable xmp to get the speed to 3600 the system doesn’t boot

Tested:
- When 1 x 16gb kit is removed then the system boots
-When disabling xmp with both kits installed then the system boots with ram speed at 2666

Hardware:
-Gigabyte X570 Aorus Elite
-Amd Ryzen 5800X
-2 x Corsair vengeance pro ryzen optimised kits (Part number- CMW16GX4M2Z3600C18)

Questions
-Can Amd ryzen run 3600mhz ram speeds?
-Should i rather exchange both kits and get 1x 4 stick 32gb 3200 kit?
 
1) Yes AMD can easily run Ram rated 3600
2) No, single channel ram is a nope

Could try the following:
1) update bios
2) try 3466MHZ
3) If stable, try 3600 but bump up volts a bit
 
Same for me. BIOS update will solve that problem.

Mine is perfectly stable at 3333Mhz.
 
AMD memory timings are a bit of an ordeal and won't always work using XMP (it's essentially just a baked in OC profile). Using 4 modules just complicates matters. Try entering the manufacturer specced memory timings manually (and voltage) and see if that gets you booting; from there you can tweak.

Otherwise if you really feel like going down a rabbit hole, download Thaiphoon Burner and Ryzen DRAM Calculator. Then go google for some tutorials on how to use these to get your timings right.
 
Most 16GB kits will be dual rank. That's something to consider. Uhm I've never overclocked on Ryzen but I assume you're going to need to have a look at your SoC and your fabric voltages as dual rank often will require more supporting voltages from the memory controller. If they're Ryzen optimized then it means those speeds and timings have been certified to work with Ryzen, and I doubt 3600 would be an issue.

I don't think the speeds, timings, or DRAM voltage are the real culprits, although you obviously could get your system stable by adjusting them. When you do eventually get it working, defs run HCI MemTest with an instance for each CPU thread, and test all available RAM to 400% coverage. Page file BSODs are the worst and unstable RAM can leave your OS corrupted after a while.

Response from corsair support :

Yes but it wont be a matched kit. Matched kits are tested to work together out of the box, while it likely wont be an issue you might have issues hitting XMP when you mix 2 kits even with the same part number
 
I've already updated the bios to the lastest in order for a ryzen 5000 series cpu to work however the issue still persists

i’ll try setting the timing/speed manually , hopefully that will work

Thanks for all help :)
 
Had a similar issue on my 2700x, and my 3950x when I got it.
Bios update helped the 3950x, but on the 2700x I had to enable XMP, then also up the voltage to 1.37v (default was 1.35v)

Increase the voltage to 1.35v. Manually set the speed.

I hate Gigabytes BIOS. It’s not good.

Well with XMP on AMD it doesn't seem to just be a Gigabyte thing tbh.
My 2700x was running on a Asus B450-F, the 3950x was on my current Aorus Xtreme.
However the 5950x just enabled XMP and off I went.

I do however have a speshul issue where I can't control the rgb of my Trident Z ram now all of a sardine for some reason regardless of whether I use the Trident-Z app or RGB Fusion 2.0.

Ill try reseating my ram tomorrow probably and see if that solves my issue like it did with the 3950x.
Actually in the 3950x's case I swapped out the ram for a different kit (Neo's) then went back to the Trident-Z RGB's and it worked fine after that, so might try this with the 5950x installed again and see if that solves my rg-blues.
 
I experienced similar issues with my Aorus Pro motherboard (will have similar bios).

the fix was basically ...
select the ram profile (XMP / DOCP / whatever on your motherboard),
fill in the timings the same as the profile sets them.
Set ram multiplier to appropriate number.
Set the sixth timing (tRC) to 56 instead of 54 as XMP would important!
I also set the DRAM voltage to 1.36

Not guaranteed to work... but when I manually set tRC to 56 instead of 54 my problems went away and I could run benchmarks and it's now been working like that for months.
 
I couldn't get the corsair kit to work correctly so i replaced it with a 32gb trident z neo kit and the system now runs stable
 
More RAM slots used = more pressure on the IMC = less likelihood of a higher overall OC on your RAM & usually a higher voltage will be needed. If you've mixed kits, check that both kits are on the QVL list for your mobo.

A quick search for Nanya A-die overclocking suggests that these are pretty shoddy chips.

I think you got an early DRAM module type that doesn't play nicely with the CPU. I'd be surprised if they were on the QVL list of a vendor and I'd also struggle to think that they have been made compatible for anything other than Intel.

If you got TridentZ Neo, there's a strong case that you may have gotten Samsung B Die so you can tighten up those timings and get very good performance.

If you post the RAM kits model number, I can tell you what you got.

So on my mobo QVL the exact part number was listed however listing the DRAM Brand as Micron , The modules I got were manufactured in late 2020 so I'm assuming corsair changed the DRAM manufacturer from Micron to Nanya somewhere along the line

The TridentZ Neo kit i got has sk hynix die`s (F4-3600C16D-32GTZNC) which was +-30% cheaper then the b die equivalent kit
