What 16gb ddr4 ram for a desktop pc ?

[Lorec]

I have g.skill flare x 3200mhz cl14 on my msi x470 gaming plus mobo.
I just checked QVL and my ram sticks are not on the list.
When I was buying ram I chose Samsung Bdie tested with ryzen.
XMP works out of the box.
?

One problem i have if ram settings or ram settings and MABYE cpu is oced so it's not stable, is that i get bsod, when i set cpu and mostly ram to more safe setting my pc boots up normal

One of them being system32 ntoskrnl.exe 0xc0000428 and sometimes another number i don't get it if my ram basically runs at safe setting

Tried this

2666mhz it's stable standard ibt

How is the fluctuation from the cpu,is it safe?

To me it's almost as if and engine runs with different rpm from the pistons, the speed from the diffferent cores goes up and down in speed all the time, is that okay when it does it all the time?

 

[Lorec]

I dont like ibt. How about You stress test Your PC in actual workloads You planned it for? That is games.

I have no clue what is that video about, neither does the bro who made it.

Cpu clock will fluctuate bcoz fsb does.
Very slightly I mind You.

On stock, some cores will go 3.9ghz others will stay 3.4.
That is why You need to set in bios that OC applies to all cores. It may need more voltage than auto can offer so for example 4ghz all cores at 1.3V

How about You clear all changes and start from the scratch.
1) Your cpu and ram on stock
2) Your ram at rated xmp speeds
3) OC Your cpu from ryzen master
4) Check stability in actual worloads

Just run everything stock... every change you've made has a negligible effect on actual performance

that ram kit on stock will run at 2133mhz... that will lower his ryzen performance considerably.
thats how ryzen works.

 

[gasolin]

yes ryzen like fast ram alot more then intel.

when oc is unstable i often get bsod or ibt within less then 5 min being unstable

Mabye vcore is to low at 4ghz around 1.29375 volt or just under 1.300 volt at 4ghz.

Atm im at 2800 mhz (highest ram speed specified in the asus manual before max rated ram speed from corsair 2933mhz and 3000mhz), it only wants to run the ram at cl 15 when the mhz is very low

When i had flare x 3200 mhz cl14 i couldn't get it stable higher then 2933mhz but only 100% stable at lower mhz i thought that ram on the Qvl list would run better relative to there rated max they have regardless what type of ram they are (samsung b, sk hynix....).

 

[Lorec]

Atm im at 2800 mhz (highest ram speed specified in the asus manual before max rated ram speed from corsair 2933mhz and 3000mhz)

highest specified is 3600mhz from what I read on asus website.

when i had flare x 3200 mhz cl14 i couldn't get it stable higher then 2933mhz but only 100% stable at lower mhz i thought that ram on the Qvl list would run better

impossible that any from qvl would run better than highly binned flare x with xmp tuned specifically for ryzen+ .
maybe at that time Your cpu overclock interrupted Your ram.

 

[Athlonite]

Havent touch my i5 for more then 6 month, not even applied new thermal paste since i got my cpu cooler

No but you may have inadvertently knocked the Cooler leading to an unsettled CPU whilst removing/moving the Dimm's around

 

[gasolin]

highest specified is 3600mhz from what I read on asus website.

highest rated ram speed before my rams rated speed 3000mhz is 2800mhz and 2933mhz

A i remember there is some mhz between 2666 mhz and 2800mhz you can choose in the bios when ocing but i have chose to use the asus rated speed which is 3000(O.C.)/2933(O.C.)/2800(O.C.)/2666/2400/2133 MHz to increase the chance of my ram running stable.

Ram timing shure looks a bit odd, right? (tRAS and tRC) For some reason i have to go low (mhz) if i want to have my ram running at cl 15. Compatibility ? I can't imagine they would say my ram should work with my mb at rated speed if it doesn't, so i must have some kind of problem not just that my ram isn't samungs b die https://dlcdnets.asus.com/pub/ASUS/...mory-QVL-Ryzen-2nd--Generation-processors.pdf

Som one in here i think it was, said that flare x isn't ryzen ram, it's threadripper ram, where trident z is ryzen ram, it's just that when ryzen was new the only ryzen rated ram was g skill flare x so i don't know why he is saying flare x is threadripper ram.

If any has the same mb and ram as i have i would appriciate it if would se what settings,timings they use and try them

Looks like its common problem with Ryzen and Corsair ram.

Also for some reanson had problems with flare x ram.

I wonder why ryzen still have ram problems

You had problem. My flare X work beautifully with my ryzen 2600

Corsair ram is pants unless you're buying the higher end stuff, though this could be a combination of that and your board not being able to run them at their rated speed despite what the qvl says as I've had better luck on my asrock ab350m board which was about £70

Not the same mb i have an asus prime x470 pro mb

I have corsair vengeance lpx ram, i have often wondered why so many wants/use corsair vengeance lpx ram, as if they are just the industry standard or just have some kind of magical speed.

I mean you can get ram as cheap and low profiled as corsair vengeance lpx ram

I bought corsair ram because they are on the qvl list, reasonable price, friday i bought them, monday the where slightly cheaper, i asked the store if i could get the difference, i was lucky to get that, no clearance problems with my cpu cooler (which is about all ram lol) and they had the ram where buy most of my hardware.

 

[NdMk2o1o]

If you're around 2800+ then you'll see no discernable difference trying to push them much higher anyway so I wouldn't worry too much about it, I wouldn't want any lower as on ryzen the performance does start to take a hit and there's quite a difference between 2133/2800-3000mhz from there I'd try lowering the timings and stick with that.

 

[gasolin]

As mentioned a few times it only seems like at a very low mhz i can run the ram at cl 15

I have to google my mb and ram to see what what people can run the ram at and how they do it (older bios, special settings....)

I would like to run my ram ast fast as possible (3200mhz cl15) and stock cpu, try lowering vcore when all is stable (if temps are stable not fluctuating because of the cpu changing speed alot) or high cpu speed 4.2ghz and mabye ram would just run 2800mhz, slightly lower then rated speed.

those corsair sticks are not meant to run at that speed, you cant even get them at 3000mhz.
take 2800mhz if You cant better.
Im not really sure but I think clocks are more important than timings in this case.
makes infinity fabric run at 1400mhz which controls everything so yeah...

EDIT:
Definitely ram clock is more important than cpu clock.

They need som strange high timings relative triede vengeance lpx 3000 mhz cl 16 setting but i can tRAS was set til 36 not 38

 

[kapone32]

I really rate Asrock boards, I've had constant bios updates for 2 years and apart from maybe the first bios, all the RAM I have used on it has been able to run at it's rated speed even when I had 2 mismatched sticks of ddr4 2800, one was corsair and the other was gskill I think, but they ran together at 2800mhz for the best part of a year and a half. The teamgroup ones in my specs aren't even in the QVL but ran at 3000 16.18.18 their rated speed as soon as I popped them in and now run at 3200 14.17.17 happily, can't seem to get above 3200 though I'm thinking that's probably more down to the 1st gen Ryzen IMC than the RAM.

I have used GIgabyte and Asus boards on AM4 and all the boards I build for clients now are As Rock. Why? As Rock is the best MB vendor in my opinion for Ryzenm including TR4

seems that with those sticks on that board this is the sweet spot lol enjoy

well im an msi fanboy myself so yeah.
lack of proper troubleshooting hurts but I gotta say I love the bios.

I can't speak for MSI I have not used one of their boards recently. I have been thinking of getting one.

new update

First 3.6ghz and 2933 mhz 16 20 20 36 69 1t

I changed the speed to 3.8 ghz and 38 in the ram settings, unstable so i changed back from 38 to 36 and more vcore (it needs alot) now on 4ghz 16 20 20 36 69 1t and 1.400 volt max temps in ibt standard 74c digi+vrm settings i can't remember

Im going for 3000mhz and im gonna lower vcore at 4ghz to minimize heat,hoping when my 2'nd scythe mugen 5 fan arrives i can get max 70c at 4ghz and lower vcore with 2 fans

Next im gonna try ibt above standard

Ram timings are way of cpu z, the rated timings, i have tried alot of asus,asrock,gigabyte and msi mb's in less then 10 years.

I like asus bios more then, let's say gigabyte, i once tried there absolut top mb for ryzen, i can tell you one thing about this board, it was sooo choppy,lagging when moving the mouse in the bios, even when i could make dpi higher, the cursor in the bios move extremly slow and lagging.

Never experienced something that horribly thing another thing is the bios was a bit limiting in features it felt old, disapointing for gigabytes best mb.

Thought a top of the line mb would last me into ryzen 3000, it couldn't.

 

[NdMk2o1o]

Have you changed the soc voltage? 1.15 is the safest recommended iirc and could help with ram instability. I have mine set so where between 1.125-1.15 (can't recall off the top of my head) and vram is at 1.4v and I've never had a memory related crash or bsod though ymmv with your board. Also I think it's trfc (usually between 250 - 450/500ish) I had to manually change mine from what ryzen calculator recommended as it wasn't stable until I set this quite high to 425 from about 300. Are you using ryzen calculator? I decided not to in the end as I couldn't get my ram stable using all the recommended settings and used my stock xmp profile instead just tweaking the main timings, trfc and voltage.

 

[gasolin]

I have changed soc but only to 0.98750 i think, maybe that is stock value, im not shure, load line calibration to level 2 and either 110% or 120% those with % in value (can't remember what they are called)

Just feel that it's extreme timings i have to have to get it stable at 2933mhz 18 20 20 36 69

Stock i 15 17 17 35 53 at 3000mhz

I have tried ryzen ram calculator, have never worked for me

As you can se in the link vcore is pretty high if i lower i get all kinds of bsod or my pc won't boote or reboote, i think it set to 1.4750 and raised load line calibration to level 2 cpu and soc

prime 95 small fft 75c ibt high can go up to 78-80 in the most extreme situation with som settings that gave me most heat. my scond fan is on it's way so i should get it tomorrow (nice)

https://valid.x86.fr/vvn944

max vcore for a ryzen 5 2600X ?

Raising soc made more workers stop in prime 95 blend (lots of ram testing).

Atm ram is at 2800mhz 14 18 18 49 67 (hwinfo64 settings except for 18 18 that should be 16 16 and i think i used 16 16) vcore 1.375volt.

cl 14 omg, prime 95 blend runs fine no workers stopped.



Final update

From another forum (my thread)

Take all RAM out except a single stick. After that, flash the latest bios (uefi). Then add the other RAM and load DOCP in uefi.


With 1 ram stick i didn't seem to be able to boote in to the bios, tried diffferent combinations (ram slots), wouldn't se my flash drive so i used my drive c



Installed bios, rebooted and shut down my pc so i could put in the last ram stick in my mb (grey slot witch is not recommeded for 2 ram sticks, i just don't wanna tempt fate and try the black ram slots) did disable fast boot and cpu stock (gonna oc it, i kind of get some ocd when speed is fluctuation that much with the cpu on aut)



booted a bit slow do to disabling fast boot, i checked settings (se pictures) thought what the hell (i don't wanna try cl15) and only have to reboote since i forgot to make a custom fan cure for my fans and set speed to 38 or 40.


Ibt seems fine as well as prime 95
