How would 3200mhz sticks work? I've ordered some Team Group Vulcan Z-Force 32gb (2x16) 3200mhz memory, but wondering if I maybe shall upgrade to the Corsair Vengeance LPX 32 gb (2x16gb) 3600mhz?

3200 will work well!...you can always tighten timings...
But my favorite at the moment on AMD are the "Ripped" kits....

Apologies to hijack this thread, im in the same boat and confused which to go for...the 3600 CAS 14 or the 4000 cas 18 ?

Personally I'd go with the tight timings on the 3600....
Which is backed up by this table that plots read times according to clock speed and timings (basically showing that 3600/14 achieves better read times than 4000/18) -> https://docs.google.com/spreadsheets/d/1Qo0VGd4waXGfI3jXt5jF9ORxeLpXgEWvpnYKaXjWtgQ/edit#gid=0
Sisnr AMD claim that the new Cpus will work perfectly with 3200 ram?
3200 vs 4000 there maybe be a slight difference. 3600 would be my choice. No point paying another £150 more for very very little performance increase. It's a great example of diminishing returns unless you're rich and have money to near enough throw away. But that's just my opinion.

So my system is up and running now with the 5900x.
Am I better off sticking with 3200 and trying to get the timings down.
Or trying to get to 3600 at the cost of timings.
I'm assuming it's a compromise, if I up the speed, the timings will have to slacken to cope?
Then I set the fabric to half of whatever my ram is at to match?
Its currently on 1000 in Ryzen Master

CustomPC magazine reviewed Ryzen 5000 RAM needs in this issue #208 concluding:
"Despite a slight upshift in the 1:1 Infinity Fabric ratio, there's not much point in buying 3800MHz+ memory for a Zen 3 system. A 3466MHz or 3600MHz kit will be more than adaquate. The only situation where you should be opt (sic) for faster memory is if the prices come down to a point where it makes sense to spend an extra £10 just to squeeze out every last drop of performance."

You know the old rule of thumb formula for speeds? (CAS/frequency) x 2000 gives you a number in nanoseconds for comparing....
3600 will be faster if timings are not increased to the point of diminished returns....3200 will be faster if 3600 needs cas 20 for example...just have to experiment a bit with what you have...try DRAM voltage to 1.45...safe for 24/7 stuff and see what you can get...3600 C16....3200 C14?...use AIDA64 to test...use your games to test!
