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

Daft as these might sound -
Have you tried pulling the ram and putting it back in again....maybe even swapping them over
Did you try a complete reset to default to rule out any left over settings such as infinity fabric settings
Are you sure the mhz you're setting is not overclocking it, I've got an msi board so not sure how different asus bios is.
Did you try upping the ram voltage a little, sure I read somewhere it was needed in some cases (my 2x32gb corsair vengeance lpx 3600 didn't need this though)
 
i have no support for your question other than thats old ass ram.... and very slow and we all know AMD feed off ram speed..
budget 3600Mhz would be so much better than what you have.... if it was stable that is.
 
I know it seems unlikely and maybe you have tried it but when I replaced my son's 2600 with a 3600x I could not get it to play ball with two sticks if Ram at the xmp profile. I was all ready to send it back but then reseated the CPU and all was well. If you haven't tried it then I would recommend doing so

I'd manually set the ram and put a bit of extra voltage to the SoC. The memory controller in zen3 should easily be able to hit 3200.

I managed to get my 3960x at 3466 across 8 sticks and the memory controller in that is weaker than in zen3 I did have ti set it manually and add a bit of voltage as xmp I just couldn't get stable.

unless you have individually tested the controllers you don't know what his chip can or cant do.
adding Extra voltage doesn't always make better.

he may very well have a faulty chip(weak controller)
But if thats some old ass Dominator not the new stuff and with the speed am going to say yes... it could just be not very ryzen friendly.
if you can get other ram to test, i would

You are somewhat correct but the memory controller on zen 3 is significantly improved over zen2 and rated for higher speed, with my current configuration the controller is only rated at 2133 on zen2 and my ram is technically not "supported" so its manual all the way.

Put simply you should be able to get memory even older crap working at rated speed if that rated speed is only 3200 on zen3.

We all know that xmp on zen just in general doesn't always work (hence the new standard) so manually set with a small bump in voltages is the way to go if you don't fancy buying new memory. My memory is like 4/5 years old and doesn't work on zen if you just switch on xmp and hope. Worth a try in my opinion before shelling out, you might even get a decent overclock on it setting manual timings... managed to get mine up to 3600 on zen2 across 8x8gb sticks but ended up way to high load line and voltages too high to tame the heat output of my chip.

It's not THAT much better and if it's dual rank 3200, it'll be faster than a lot of other kits of RAM. I've got an old kit of 3200 Dual rank Samsung D die and it's faster than my single rank 3600CL14 kit.

Reseat everything, including the CPU and RAM.
 
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

Honestly that still doesn't feel right....
I'm running a 5950x on a b550 and it's more than happy to run my 2x32gb corsair vengeance lpx 3600 at xmp settings, along with an 1800 infinity fabric, with no changes to any other settings... I highly doubt a 570 would have an issue doing 3200 and 1600 infinity frabric.

Is the ram running at 1.35v, I know I need to run mine at 1.35v to get it's 3600 xmp profile, based on the corsair website yours would need this for 3200 xmp.

Have you given corsair a shout, they might have run into this issue before and know the fix?

if its only a year old it was never top tier ram at 3200mhz.
the fact its running at 2800 say there is a problem.

i dont care what other on hear say 2800 top spec vs 3600 budget in games is a massive difference it been tested by ever YouTube tester, dual or single rank aside
 
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.

so there is your answer.
the ram is flawless it worked perfectly with you 2 old chips (that you must have owned in the last 12 months because that when you got the ram hahah) but now the ram is been a little bugger. whats changed.

TBF the advice to reseat your chip is no bad, i had to reseat my 6700k a few times before it would boot with 2 sticks of ram the LGA socket is not without faults


EDIT: Just noticed this and it could be your problem.

tRCD timing is known to be a high clock on AMD, When you get AMD ram is almost always high, with your ram been old XMP could be setting it low as AM4 wasn't a thing when your ram was made.
my ram out of the box is 22 22 22 44 . . . . . i can oc it to 15 20 16 16 1T the tRCD will not drop 100% fail rate no matter what i do

Save the setting you have, set XMP on the ram, Ram voltage to 1.35v soc to 1.05v but change the TRCD (second timing) to 20 and see if you get a post

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

at XMP what would the second timing be at? 18-20-20-20 thats the one thats known to make problems unless you have golden IC's
 
kully1972 said:
the xmp timings are 16-18-18-18 so should be ok
Click to expand...

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.
i have this https://www.overclockers.co.uk/cors...ry-dual-kit-cmw16gx4m2z3600c18-my-4c1-cs.html
