Hi guys im wondering if anyone can help me quite new to the forum so go easy please

My Basic system spec:
MSI MPG X570 GAMING EDGE WIFI
Ryzen 9 3900X
RX580 GFX
Thermaltake TOUGHRAM RGB 32GB (4x8GB) DDR4 4400Mhz C19 Memory

The issue im having is getting the memory to run at its full potential 4400mhz.
Msi website suggests this memory is compatible with my motherboard
motherboard specs are as follows:

DDR4 Momory up to 128gb: 1866/ 2133/ 2400/ 2667/ 2800/2933 /3000 /3066 /3200 /3466 /3600 /3733 /3866 /4000 /4133 /4266 /4400 + Mhz by JEDEC and A-XMP OC MODE

The memory i purchased also is showing as compatible : R009D408GX2-4400C19A Ver:1.1.4

However the issue im having is i can get 32gb 4x8gb to run at 4400mhz
The most stable i can get this working is 3866mhz at 1.5v over the suggested 1.45v
However if u run just 16gb 2x8gb i can run it at 4400mhz at 1.5v.

now i cant get my head around why it will run 16gb and not 32gb , my psu is a RM750 so should be enough power . my only though is a motherboard limitation? or perhaps because the memory has RGB lights so it taking up extra power?

I have contacted both msi and thermaltake and awaiting responce.

does anyone have any experience in this or could help me configure this memory? after paying £300 im a little disapointed at it only running at 3866mhz over 4400mhz as i could have saved £100 and just brought 4400mhz memory.

Thanks in advance
 
its not a power issue
ram doesnt use much power
will be to do with the infinity fabric/fclck
something to do with over around 3700mhz/3866mhz?
you cant run 1 to 1 infinity fabric to ram
forgot exact details
and i just got tough ram 3600mhz 32gb
great rgb and decent rgb software for a change
but had to rma the first lot as wouldnt run more than
3 modules at once
i would aim at 3733mhz/3866mhz and see how far you can tighten
the timings
i am not a ram expert though some one knows more than me
is bound to come along and help you better
 
Thanks for your replys guys, I had a response from MSI saying similar , because I brought 2 16gb 2x8gb kits, so ideally I need to be looking at buying a 32gb kit , but from what I can see it's better value for me to just run my 32gb ram at 3866mhz than to spend out on a 32gb 4000mhz kit.
Ideall quite disappointed but I guess nothing is ever simple.
 
You can probably get it to run a bit higher
By not using 1:1 ratio on infinity fabric
But that may not benefit you
Ie you gain ram speed but lose something else
Go for 3866mhz and tighten the cas timings
Next gen amd I think will support a bit higher speed ram as default
So it's not a total loss as the 4400mhz is future proofing
 
MSI reply was the following
Thank you for your informatiom, in this case, we are really sorry, in theory, if you use two or more rams, to ensure system stability, memory modules must be of the same type and density which means the rams should be exactly the same and in one kit, or the pc maybe cannot boot up or work stable. In particular, overclocking requires a relatively high memory stability, from your description, you have installed two kits, even they are the same model, but the stability is still different, we cannot guarantee that every overclocking will succeed. Sorry for any inconvenience caused.

I feel this is a bit of a get me out of jail excuse, the motherboard boasts it can handle the memory it says it can take the speed, i cant see me buying 2 sets of pairs being any different to buying 1 set of 4 or a set of 2x16gb same speed.

im happy to run at 3866mhz for now , the timings are 19-25-25-45 - though i have read that can also be ran at 20-25-25-45. i would ideally like to find a way to get the voltage down to 1.45 as suggested by thermaltake as not sure 1.5v is any good for the memory or not.
Im not an expert at overclocking or memory timings if anyone has any suggestive bios changes id be happy to give them a try.
 
4400 memory being compatible does not mean they guarantee it to run at max speed in all configurations imaginable.

Ryzen mem and Fabric sweet spot is in the 3600 - 3800 range.
What do you hope to achieve by trying to push the memory to 4400?

I have 4400 memory but I never expected to run it above 3800. It runs at 3800 Mem and IF with 4 dimms with excellent membench scores and stable.
I think you may be better served by getting your memory and Infinity fabric running in the 3600 - 3800 range 1:1 with tight timings.

My memory runs at 3800 matched to IF at 16.16.16.16 which i am pretty sure will kick butt against your slower timings even at faster clocks.
In fact if you can post your best Dram calculator membench scores easy and default we may prove the point that tighter timings are better than increased clocks with slower timings.

i jst assumed with it being advertised at a set speed it would potentially run at the speed they specify.
i have played with settings and have found 3866 at 1.45v the most stable settings with the default timings of 19-25-25-45

so i guess that's the best Im going to get at the advertised voltage and timings.

tbh Ive never really ventured in to high clock speed ram this was a impulse buy thinking it would potentially speed up my machine.
Its overall must better than my old ddr4 3200 but knowing what i know now perhaps i wouldn't of spent out on the 4400mhz kit and just stuck with a 4000mhz kit.
 
You can't tighten up from 19-25-25-45 ?
And it's probably at cas 20 not 19
Unless you disabled gear down mode I don't think you can run odd cas numbers
 
Download the dram calculator.

Your timings are horribly slow and without knowing your memorys chips I will not advise anything specific.
But if your running at 3866 try lowering all the timings eg try them all at 19 if that works go down to 18 etc.
Anything would be better than the timings designed to run at 4400.

The Best memory contains Samsung "B" die chips which as already said I can run 4 x 8GB at 16.16.16.16 at 3800.
I have no idea what chips your memory has but normally if they contain "B" die they normally advertise it as such.

They're not Samsung in the 3600mhz version of toughram
Might be hynix e
Not at the pc to check mine right now
 
This is with 4x8GB 4266C17 kit from GSKILL.

ok so cant get Thaiphoon or dram calculator to work on my pc for some reason,
however i have changed the timings to 18-22-22-40 running at 3866mhz and appears to be stable so have trimmed them from 19-25-25-45
 
I think your memory is more about the Bling than tuning tbh.
But the point still stands that you should be able to experiment with those values and lower them all below standard which will be faster.
Try them all at 18 if thats OK try lower until you get errors then go back up one value.
Rough and ready but without aid from the Dram Calculator I am afraid its just experimentation.

ok so managed to get dram calculator working , it looks like my best options are to run at 3800mhz and tighten up timings

Try the other PCB revision preset. A2/B2 it's faster. Maybe not strictly the right PCB profile for your ram, but who cares. My ram is A0 but I am running the A2/B2 profile as it's much faster.
