3800x setup

[ntemples1]

Hi all,

After not having a good time with the 3900x and having to return it due to not being able to get it the memory to work at 3600, I had to return it as I bought it as part of a bundle.

Due to the high cost of the 3900X i've decided to go for the 3800X instead for now with a view to dropping in a more powerful chip in the future (as i mainly game on the PC). I have gone for the following:

Ryzen 3800X CPU
Aorus X570 AORUS ELITE
G.SKILL F4-3600C16D-16GTZR 16 GB (8 GB x 2) Trident Z RGB Series DDR4 3600 MHz Dual Channel Memory Kit
Crucial CT1000P1SSD8 P1 1 TB (3D, NAND, NVMe, PCIe, M.2

How is this looking? Hopefully I can get the Ram to run at 3600 this time!

So what was the issue with the last setup? Did OCUK not test, find what was bad and replace it?

Well I guess that list of a complete new set of components will be fine unless you are very very unlucky.

It wasn't from OCUK (my mistake) I got a bundle from another company minus the ram, 3900x + mobo, but I tried 3 different sets of Ram dual channel kits rated at 3600 but I couldn't get anything to work over 2133mhz, it would just lock up, I think it might have been a faulty CPU.

Fingers crossed this works, I amost bought a 9900k but don't want to buy old tech as this will want to last me 4-5 years hopefully especially if I drop in another more powerful chip in the future.

Oh I see.

Well from my n00b status as a RAM OCer and ryzen2 being a little fussy, it was a bit of a pain to get the RAM working, but I was a fairly early adopter. Dunno if its gotten easy to get RAM working even for native 3600 kits, mine wasn't since BIOS's AB. Was it the BIOS updates that made mine stable or my faffin with it?

Dunno, but I hope your new rig works.

My RAM advice is 8packs - change SoC to 1.1 and manually enter stock timings, not via XMP.

ONLY then if stable use DRAM calc to try OC, or shorten timings.

Fingers crossed for ya

thanks I will follow your advice. Fingers crossed!!

SoC will be 1.1volts already with some motherboards. Like mine. Too high a voltage can be as bad as too little. All my issues have been down to a voltage being too high. My advice is to only change something if you need to.

Remember stock RAM frequency is 3200. The only speed that should work 100% of the time. Going faster than this speed is limited by the IF frequency for performance reasons. Many ryzen 3800x chip can hit 1800-1900. Maximum approx. IF 1917. https://www.corsair.com/corsairmedia/sys_master/productcontent/Ryzen3000_MemoryOverclockingGuide.pdf

My BIOS for example will set VDDCR SoC to 1.1 volts, CLDO VDDP to 1.1Volts and CLDO VDDG to 1.1volts. This made IF1900 unstable (BIOS 1.0.0.3 ABBA). I had to change CLDO VDDG to 1.070 volts. Its at 1.0684 volts in Ryzen. Seems they all don't like being the same. CLDO VDDG likes to be at least 30-40mV lower than VDDCR SoC. VDDCR SoC is the Uncore power voltage. https://www.gamersnexus.net/guides/...-guidelines-how-to-kill-cpu-with-safe-voltage

When CLDO VDDG = VDDCR SoC then with harder loads there would be cracking sound and the PC would reset. VRay is really quick for doing this, you can play games 6 hours in a day and get the same problem you can find in 5 passes of vray benchmark. Also drivers like to get IO errors and you cant access then if CLDO VDDG is wrong. Userbenchmark will find that out for you in one or two runs. Otherwise you may never find that out. I have a number of SSD's and a hard drive. The hard drive would disappear from task manager or freeze explorer when you tried to browse the files after running userbenchmark.

Because this CPU boosts and drops to very stable stock settings when hit by a very big load. Its going to be hard to catch issues in aida64, memtest86 and even prime95 blend. I guess just using your system and running as many different loads as possible is the only fall back.

Every overclock should be expected to be different within reason. If you randomly set voltages you can get into a lot of trouble or cost yourself lots of time. In the end I found that just a small changes always got me stable. A small change from stock settings. Well so far anyway. That's my opinion, good luck.

Some great info there, I will have a read up thanks!

Just make sure you go by the motherboard's manual in installing the ram. Usually they are slots A2 and B2.

Got a GSkill Ripjaws V 3200MHz CL16 kit that works on both my Asus B350 and X470 boards at 3200 CL16 using DOCP and manually adding voltage set to 1.36v. Same kit runs at same spec on a MSI A320 board using DOCP with just two clicks in the BIOS. It automatically sets the dram voltage to 1.36v.

Noted, i'm all up for changing as little as possible to achieve a safe 3600 overclock, don't want to be greedy just have a nice stable system. thanks again for the advice!

Hopefully you can just set IF to 1800 and the RAM to 3600.

hehe yes that's what I am hoping for!!

 

[ntemples1]

Yes it was an MSI x570 board, I also tried it on a gigabyte board though and had exactly the same problem so I might have had a bad cpu.

 

[ntemples1]

Built today, and updated to latest bios then switched on xmp and it just worked!!! So happy right now (sad isn’t it)!!

Great news shame your previous setup didn't want to play ball however 3800x should serve you well until either another 3900x or maybe even a 4000 series next year, can't say I need more than my 3700x is giving me

Thanks, yes it’s an ice upgrade from my 4770k!! I might drop a 3950X in when they come out!!
