I can’t run my ram at advertised speeds without instability, I’m running 4 sticks of DDR5 with default xmp profile and getting BSODS. Is there any workaround?
You need to give us more details about your parts as there’s a chance you are missing something in the specs. The most likely option is you actually have a defective component.
The advertised speed on RAM sticks is what the RAM itself is specified to run at.
It does not in any way take in to account the memory controller (Inside the CPU) being capable of handling such speeds. It is also highly dependent on motherboard voltage settings and timings.
My old motherboard for example required a bump in System Agent voltage to run XMP profiles correctly, something that was later adjusted in a firmware update when you enable XMP.It is also worth remembering that the more sticks you have, the harder it is to achieve the highest speeds. Less sticks = always better.
Less sticks = always better.
I disagree. Dual channel is better and stock clocks on dual channel will outperform a single overclocked stick
He probably means only using two sticks instead of four. Some main boards can be flaky filling all the RAM slots.
Oh yeah, 2 is the sweet spot. 4 can be flaky but 2 beats 1 stick for performance
BIOS update the board, they often add better ram/clocking support. … do it with like one stick of ram in so it doesn’t bork while updating lol
Yep. Any research into DDR5 and you would know how Intel AND AMD are both having issues running more than 2 sticks.
Afaik there’s no fix, run 2 or wait for a bios update
Keep in mind this is the case for RAM in general. Even DDR4 and DDR3. As soon as you try to add more than 2 dimms you need to dial back the frequency or youll have stability issues. Its just common RAM knowledge
It used to be the case. DDR5 is just very new, and hasn’t really matured quite yet. Let Intel and AMD have a year or two of trial and error and it will be fine.
But for now, it’s 2 sticks or nothing
Itll still be two sticks in the future. I just checked myself to confirm. Looking at even Z790 boards that take DDR4 the higher you go in capacity and slots used the slower the board supports. Its not a matter of DDR5 or not. Just dont run 4 DIMMS if you dont have to or if you prefer speed
Max speed w/ 4 DIMM being lower does not mean that you can’t run 4 supported sticks at their advertised speed, it just means that the fastest sticks are not supported in sets of 4. As long as you stick within the supported specs, you should expect to be fine.
Been running 4 sticks of DDR4 at the advertised 3200 MT/s on my Ryzen 5 5600x since it came out with zero issues.
3200mhz is pretty average performance, and I would expect most kits to be able to do it even with 4 sticks. When you get to the high/excessive performance 4100mhz+ ram kits that tax the memory controler more its very unlikly you will be able to run 4 sticks, however you could get lucky still. Same with ddr5 6000mhz. You could get really lucky and have it work, but it’s not a guarantee and more than likely wont.
3200mhz was pretty fast for DDR4 when it first came out. Also 6000mhz is like average ddr5 speed now, you can get much faster.
Id say the difference is the newer cpu. 5000 series is gonna have a much better memory controler than what came out when 3200 was considered fast. Im sure once we get a few new cpu gens with new architecture, then 4 sticks of 6000mhz will work pretty easily, too.
The point of my post was that 4 sticks can, and will, work. The post I replied to said it wouldn’t.
obviously 4 sticks can work on a motherboard with 4 slots
Again, not the point of the post… Reading is hard…
I have 6 rigs in the house running now using AMD 3000-5000 series CPUs, every one of them has 4 sticks of RAM at advertised clocks, and while I’ve had stability issues with certain BIOS version / chipset / CPU / RAM stick combinations, I’ve never found that 2 sticks ran more stable than 4.
For Ryzen 3000/5000 DDR4 was pretty mature. The real DDR4 issues for Ryzen were seen on Zen 1600 and 2000.
I still had trouble with a 5600x running 4 sticks, but I attribute that to a cheap MSI motherboard
Yeah some motherboards are notoriously shitty for DDR5 compatibility ( ASUS ) and unless you get a really decent kit that was AMD or INTEL specific (depending on what CPU you have of course ) for extra compatibility along with a bios update you will have a shit time with it.
Run a program to check your memory. I recommend this one. https://www.memtest.org/
Run it for multiple passes.
I once had a old computer refuse to run the ram at the right clock. Turns out a stick was bad. Caught it under warrany for the ram.
Wasn’t there something a while back where populating 4 slots of ddr5 was too much for the cpu to handle in some cases? I couldn’t find ddr5 kits when I did my build so I just stuck with ddr4 and didn’t look into the ddr5 issue.
Let me shout this to the back of the room.
There isn’t a 4 dimm kit of ddr5. Can you run 6000 with one of the kits? I would guess so, so that’s the advertised speed of the kit. Add another kit to the mix, even if it’s the same same, then you throw the “advertised speed” out the window.
Also as others have mentioned, and it is pretty crappy and getting worse. XMP is a crap shoot. And is technically still overclocking.
Unless you have a quad channel kit/mobo then this is a lie (and I’d bet money you don’t).
Only single kits of ram are “guaranteed” to work at advertised speeds. If you are going for overclocked RAM for gaming performance you should only ever be buying a single kit of ram (if you want 64GB then you should get 2x32GB not two different 2x16GB kits). Probably an expensive lesson this time around but short of returning your ram and buying a proper single kit of dual-channel ram no there is no “workaround”.
I have 2 matching sets of 2 sticks, and they will run at their advertised speeds, but only because they are DDR5 5600. At 6000, they are unstable, and lots of DDR5 kits or sticks are unstable right now with 4 sticks and high speeds. this is growing pains. not that long ago, getting 4 sticks of DDR4 3800 to run stable was impossible, and now you can do it with a button press.
There is no such thing as 2 matching sets of 2 sticks, they were not QA’d to run together and are not guaranteed to run at advertised speeds when you mix 2 different kits even if they are packaged as the same SKU/timings.
It is not “growing” pains, this is literally what ram manufacturer’s will tell you and is how it is been since before xmp profiles were even a thing in the DDR3 days.
Most ddr5 is rated for 2 channels. 4 channels isn’t the same - so if you got 2 2 stick kits it’s not rated for what you think. Only 4 channel kits are rated - all 4 dimms together in one set.
I have an Asus board with no supported combination of 4 channel, yet I use 4 channels x32gb for 128gb. My ram is trident z5 rated at 6900mhz but I can only get it to post at 5200mhz, and it shows errors in memtest386 at 5200. So I underclocked it to 5066 and it passes all 4 passes of memtest386 successfully.
So I have 128gb of rram, 933mhz slower than rated, 100% stable.
Nutshell, you might have to experiment with speeds to get a stable setup but 4 channel at a slower speed is just as fast if not faster than dual channel at rated speeds.
If you want 4 channels, you need a platform that supports 4 channels (ie: use 1 DIMM per channel to get full rated speed and stability). Putting a 4 channel kit on a dual channel board is going to have the same result you’re already dealing with. 2 DIMMs per channel simply isn’t as stable.
Yeah, I have a 14900k with 2 990’s in RAID 0 and a 4080, so a small hit in ram perf isn’t a deal breaker. I have to have 128gb of ram for work, so accept the slightly slower clock speed.
I’m not jonesing for frames. I have a 240fps gsynch g9 and run 120fps in pretty much every AAA game.
Mostly just telling OP to slow the memory down a bit and they’ll be ok most likely.
My machine is 100% stable on 4 channel even though it’s not officially supported at 5066mhz.
14900k
LGA1700 is only dual channel.
4 slots != 4 channels.
4 sticks are much harder to run.
let me guess, you bought two dual stick ram?
Are all the sticks from the same kit eg you bought 4 sticks and they came in same packet
Need your specs.
Mainboard model?
Cpu model?
You try changing the clock speeds and voltage manually?
In the mainboards memory qvl list do they state that they tested 4 sticks of your ram?
