ram speed and only 50% usable

[Aleximus96]

Hello i just built my frist gaming pc, and i am loosing myself in the bios, the specs are

Ryzen 5 1600x
Strix x370-F Gaming
2x8 GB DDR4 G. Skil Ripjaws V 3000Mhz
R7 360 2gb
Patriot Burst 240GB SSD
LC Power 600W

Now, i finished a build and it was all working correctly, when i am in windows i can only use 7.93GB of my 16GB, and the rest is "Hardware Reserved" also the memory is running at 2133, i tried loading it with pre configured profiles at 3000 or 2666 but after save and restart, my PC powers on and beeps 3 times fast, and powers off, it cycle's like that 4 times, and 5th time it beeps once and shows me failed settings in bios. I have checked twitce and my sticks are in correct seats, by asus manual it shows to use A2 and B2 frist and that's what i am using.
I can't really find answers, cus the most things people say the rest of memory is configured to give to iGPU, but the 1600x doesn't have one. i am really confused, and would really appriciate your help.

Thank you, Also sorry for my english it's not my native lang.

What CL timings are the Ripjaws v?

If it's CL 15, they're using Hynix chips and Hynix over speeds of 2400MHz had trouble running on first gen Ryzen boards which bios update addresses.

CL 14 uses Samsung chips and usually less trouble reaching those speeds.

Update your bios to the newest revision and clear cmos.

So i was very skeptical about doing a bios update, and i finally told myself to try it, it went smoothly, and all 16GB are now usable. i am sorry i posted here without trying this but i was scared and didn't think that a bios from 4th December 2017. would have this weird bugg.

Still i would very much like to get an answer how to run my RAM at native speed (3000 mhz) from 2133, i have no idea how much impact can this have on photoshop and games. but still if it's rated for it why shouldn't i use it at it. I read you have to mannualy change the timings, i am kinda okay with it, but do you need to bump the voltage a bit more ? mine is at auto (1.200V).

Again sorry for posting without checking the bios update. But still would really much like someone who knows this stuff to give me explanation, it would really mean so much to me.

The only thing I would touch that PSU with is a fire extinguisher.
Right no gpu with that cpu and even if it did it takes a max of 2gb of ram from usable store.
Those beeps mean your setting something wrong. Try clearing the cmos and let it do defaults see what you get, if your memory is all there then you screwed something up try not to do that again.
Same problem then try updating your bios and see what you get.
Try moving the ram to different slots ?
Try with one stick at a time if they both work singly then put them both back in and see what it does.
Theres a lot of trial and error in these cases.
Good luck

Yo, thanks for the post, the ram timings are : CL15-16-16-35 1.35V and the spec in name are F4-3000C15D-16GVRB.
so should i just go in bios adress the speed to 3000, set the timings as listed, and bumpb the voltage to 1.35 and it should work? Or is it as you say not possible above 2400Mhz with Hynix chips?

 

[richardvday]

Right you posted as I was writing, 1.35 volts for that memory

Yo thanks for the GL man appriciate it, i updated the bios now works all 16 Gigs, althou the speed is still 2133, Yeah the PSu is kinda garbage, but it worked for me like 7 years no problem, expect lousy fan after 5 y, i oiled it up and it still smacks, my previous configuration used athlon ii x4 640 and Radeon HD 4850 GS, with 8 pin power, so i was thinking on going with it now that i have a gpu with 6 pin and similar cpu power req. geuss it wont blow now, haha, i am aiming to buy a better one really soon, but for now it get's the job done (hopefully xd).

Edit : You too xD, so just adress the voltage timings and frequency?

 

[Aleximus96]

Updated : Just went into bios adjusted the speed to 3000, and upded the voltage to 1.35, then went into timings, and holy hell, there was like 25-35 differenct options, all named similar like "trv" , "trdv", "trddv" "trdvv" ... and so on, so i just got out without saving haha. any help ?

Leave timings as is and bump the voltage up to 1.35v as tested by G.Skill. 1.2v is standard voltage upto 2400MHz, anything higher requires 1.35v.

[Aleximus96]

Okay thanks, i will try it tomorrow

 

[Aleximus96]

Update : Went into bios, changed to 3000, bumped the voltage to 1.3500V went in to check cinebench lost 3 points, lel, i mean it's still between margine of error, althou my timings went from 15-ish to 21-ish. So i geuss i can benefit only by lowering the latency but meh, i geuss i got my answer, thanks for your answers everyone. and have a great day.

From 0.40s, XMP, should come up there with your memory profile 'XMP DDR4 3000 15-16-16-35-1'

Having memory on manual the timings will be all over the place. Set to XMP if you can and double check voltage remains to 1.35v. Your performance score should be better.
