5950x won’t play ball with 3200mhz xmp profile!

I’ve just upgraded my cpu from a 5800x to a 5950x in an ASUS crosshair impact viii Itx board.
I’ve tried manually setting timings instead of docp/xmp profile but no joy
Tried upping soc voltage to 1.1, again to no avail.
I’m currently using it at 2133 mhz but at least it’s stable and I can game.
Memory is 2x 16gb Corsair dominator 3200 mhz ram.
Would it be worth buying micron ram such as g skill trident neo?
I’m running the latest bios and even frequency of 2400 mhz fails whilst gaming.
Any advice much appreciated

Everyone thank you for all your advice
I’ve had some success
Managed to game without crashing (battlefield 2042 appears to be a very good test) at 2800 mhz with soc voltage set to 1.050
Adding further voltage and to other cod voltage parameters does not increase stability at higher frequencies.
I’m happy with this as 2800mhz means infinity fabric is running at a respectable 1400 mhz
I’ve saved me some dosh
The dominator ram is only a year old btw and was top tier memory when I bought it.

Dominator Platinum RAM can be some of the best, even if it's old. I'd try get it to full speed and set infinity fabric to 1600 but it'll probably not make a huge amount of difference in an online game.

Do you know if it's single rank or dual rank? You can use CPU-z to see.

Open CPU-z
SPD > RANKs
MEMORY TAB>CHANNEL# (should be 2 by 64bit)

Yes it’s dual rank and it says 2x64 bit
Thanks for replying
 
ive had time to tinker with settings:
ive got it overclocked and fully stable at 3333mhz with 1.050 on the SOC and dram voltage is set to 1.35v. Cas timings have been loosened to 20-20-20-55-78
The ram is fine as it ran flawlessly with my previous 3900x and 5800x
The 5800x was faulty as I could only boot with 1 stick of ram hence have replaced it with a 5950x.

I re-seated the ram and TBH not happy to re-seat CPU and besides ive got a stable setting which im happy with.
Still fine-tuning and am now running at 3266mhz with 18-20-20-20 timings- played four games of bf 2042 and zero crashes

this what im saying on a few ram kits i have you cant get the second timing tRCD lower than 19 and your XMP want to set 18 now you have it at 20 its playing nice.

my ram out of the box is 18 22 22 22 42 i can drop it to 15 20 16 16 36.
no matter what voltage or other setting i do tRCD will not drop below 20

you should find a Ryzen turned kit and copy the timing's then try to push the speed up, my kit will do 4200mhz on the lower timing but my IF wont pass 1900 so im running at 3800mhz.

Thanks wing-man
I’ve just bought some 32gb g skill for 90 quid on fleabay

f4‑3600c18d‑32gtzn​

Should offer better stability
 
I must admit dominator ram has been rock solid past 2 days and have gamed profusely.
I’ll keep the newly acquired g skill ram as it was a slight bargain as well and will slot it in once I get the itch to do so!
 
thought Id give one last update
managed to overclock Corsair dominator ram to 3600mhz cas 20-21-21-48-65 fully stable
I`ll try the g skill ram and attempt an overclock at a later date.
AIDA64 benchmarks look good with read/write speeds at around 54000 mb/s, copy speeds 51000 and latency is 74 ns. All in all pretty good
