What 16gb ddr4 ram for a desktop pc ?

[gasolin]

After a short period with a rtx 2060 i switced back to my rx 580 and for some reason i got black screen,having trouble starting my pc,reboot,updatede my bios........



I change the ram speed of my 3200mhz cl 14 flare x ram and it could run at 2933 and 2666mhz (now only able to on run aut at 2400mhz, 2666mhz it won't) and my pc booted and rebooted fine.



Easiest way to test my ram is to buy a new pair of ram to se if they can run above my current speed 2400mhz and 2666mhz, which is more easy than having to buy a new mb an try that with my ryzen flare x ram.



Just don't know what to buy since i need a new pair if i have to rma my ram


G.Skill RipjawsV DDR4-3200 C16 DC - 16GB F4-3200C16D-16GVGB

Corsair Vengeance LPX DDR4-3200 C16 RD DC - 16GB CMK16GX4M2B3200C16R

Kingston HyperX Pred DDR4-3200 DC - 16GB HX432C16PB3K2/16

G.Skill RipjawsV DDR4-3600 C19 DC - 16GB F4-3600C19D-16GVRB


That's about the cheapest ram i can get delivered monday if i order them today or early tomorrow, cpu i5 8400

My mb is an Asus TUF Z370-PRO GAMING

Ehh I read GPU swap and my first thought is 'DDU'.. start fresh, reinstall OS and/or double check driver conflicts

Not seeing how BIOS updates are needed because you used the card before.

I updated my bios because there was a newer bios and it might fix my ram (not vram) problems

I used ddu

reset your bios, test both sticks seperately see if you can run the higher speeds on each, run memtest, reseat and clean GPU contacts/pcie slot. before you go and buy a new set.

 

[gasolin]

I have reset my bios, it gets reset every time you update the bios.

Tried the 2 grey ram slots and i for some reason don't think memtest would help me.

It's not a stability problem it's a speed/mhz problem, they can't run at there native speed 3200mhz which they have done for the whole of 2019 and the last half of 2018, you know i can't test them at a speed where they won't boot, so i have to run the ram at speed where they are stabil,running normal like 2400mhz, i don't have any problems with stability running my ram at 2400mhz.

I can only test my ram at a speed where they are stable, can memtest tell my why they can't run at 3200mhz? Its's stable at 2400mhz (aut in the bios), would memtest show any unstability,errors?

If new ram won't run at there native speed there something wrong with my mb

If there isn't any problems with the native ram speed, i have to use the ram normal, everday use, they way i use my pc to see if there is any unstability, if ther happen to be som unstability i can use memtest.

 

[NdMk2o1o]

So you can confirm trying each stick on it's own, you still can't run them higher than 2400mhz in any slot? if it's the RAM then memtest could well show up that their unstable even at 2400. I can't see 2 sticks of RAM both failing at the same time though... it could well be the board or even the CPU as the memory controller is built into it these days, but the whole point of testing the RAM 1st is to rule that out and look at the next likely culprit. This happened when you swapped GPU's, have you swapped them back and still the same issue.

 

[gasolin]

Only have 1 gpu

Could be the cpu but i personally never had cpu problems

If new ram works at native speed (like 3200 or 3600mhz) i could go back and test my current ram since it's easy to switch ram to test them

 

[NdMk2o1o]

Seems like you're going to order the RAM already, in that case get a kit from the motherboard's QVL at least you can rule out incompatibility.

 

[gasolin]

I have to try some different ram since it's stable on 2400mhz, i don't know if new ram would run at there rated speed

If they do i have to rma my ram or mabye memtest them before i send them back, same speed problem from new ram it's either the mb or cpu.

the i5-8400 has native support for 2666MHz Ram
XMP profile should allow it to run at 3200MHz unless that Ram is specific for AMD and doesn't have XMP for some reason.

 

[gasolin]

it use to run fine with xmp, atm ram testing im just not shure what speed they are running at

I found out that neither ram cpu nor graphics card was the problem

It was my pci e express slot it won't run with 3200mhz ram running at 3200mhz

Have a little bonus info, have had som artifacts on my 2'nd display.

Sometimes it bounces fine when the frames were set to 32000mhz but there was no picture or error, with open cabinet so I could see the led just above 24pin current and under the mem ok button (did not work when I tried it), i so vga light up when i rebooted, I changed to the pci express slot below and my pc botted with 3200 mhz ram running at 3200mhz, it now runs with x8 3.0 not a big loss

Unfortunately, it was the worst because a motherboard takes longer than a ram change

must me nice to afford extra sticks of RAM to fiddle with, I use G.Skill NT and simply overclocked it as fast as it would go

 

[Rasmmer]

If i were you,i must buy a new one.

 

[gasolin]

so fare it works using my second pci express slot

 

[EarthDog]

I cant understand what the pcie slots have to do with how fast the memory runs. It's like fixing the brakes on your car and the heater starts working better.

I drive a French car, you'd be surprised

well it was after i had a gtx 2060 in my pc i returnede it and my ram wouldn't run 3200mhz when my gpu was in the pc express slot x16 3.0

That might be related in some way to you using an IGP instead of the dedicated GPU. It will put additional load on the CPU = power draw = might affect other voltages.

What? I never used the igpu

OK. Just going off you saying you returned the 2060 and having problems afterwards.

Right. I get it.. but it doesn't make sense as they are two unrelated systems. If that is truly happening sounds like the board, somehow, is bad. But again... they are not related items.. different trace paths, everything.

In the other slot, is the GPU running x8 speeds now I assume?

 

[gasolin]

Yes, i tried pci express slot x8 3.0 and it worked, i ordered ryzen since i had no idea if it was the mb or cpu (wanted to update cpu or gpu), if i stil have the problem i can relate it to the ram and last would be my gpu.

In the other slot, is the GPU running x8 speeds now I assume?

It was running fine at x8 3.0, i got the ram to run 3200mhz cl 14

Even when x8 3.0 3200mhz is better then x16 3.0 and 2400mhz or 2666mhz ram and almost normal speed.

Now on rysen i have to tweak it more to get the ram running at 3200mhz cl 14 (not in the qvl list but the ram is supported with the mb asus prime x470-pro according to g skíll and i know they work with a asus prime x370-pro mb)

So after tweaking i will know if the ram is unstable or the gpu (have memtested my ram)

When the ram speed was to high with my gpu in the x16 3.0 slot, i got black screen when i tried to boote, lower ram speed or changing pci express slot and it worked normal

 

[EarthDog]

Even when x8 3.0 3200mhz is better then x16 3.0 and 2400mhz or 2666mhz ram and almost normal speed.

Is it? Noticably (it isn't).

That is the thing, with Intel, that speed is nothing (3200 mhz). I don't know what happened, but it makes zero sense that switching slots affected the memory. Something else is happened that may, somehow, be a byproduct of it.

Reseat the CPU

 

[gasolin]

I don't know

So fare i have to tweak ram a bit to get it to run 3200mhz and i have 14 days to return it and get all of my money back if returned with no damage

I think i will keep it even when a i5 8400 is better in games since i have big expertations for ryzen 3 that they present late may

Reseat the CPU

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