Overcloocking help?-

[claudinho7]

Hello, im building my new pc and im almost up and ready, i dont have much experience with OC tho so id like to know some safe but competitive numbers for my build. Will be use only for gaming.

 

Ryzen 7 3800x

Deepcool Castle 240 AIO

Aorus x570 elite

Viper Patriot 3600mhz 17c

750W 80gold+ crosair PSU

7500xt Nitro+

All that in a Lian LI O11 Air (11 fans on top of the AIO rad with 2fans)

 

What are some safe overcloocking numbers for cpu memory and maybe even gpu? And also if someone can direct me to some video about it cuz i havent used the gigabite bios before and where to find those numbers. I do own 3d mark on steam so i can stress is after and see if its stable.

CPU: max voltage 24/7 at 1.35v, read CPU core voltage SVI2 in HWinfo64 or Ryzen Master in Windows

Memory: Best samples don't top 3866MHz, and usually not beyond 3733MHz. Use 1:1 ratio for UCLK and keep FCLK (infinity fabric clock) half of memory data rate

GPU: Overclock memory first, then do the core.

You lost me after 24/7. Is there a video that would take me trough the menu to where i would find those numbers? On my curent pcwith strix x370 mobo  i had a hard time finding xmp profile on memory (which i didnt find, only that drp1 or whatever and i assumed that is xmp but didnt worked)

This board has more options than yours but the important bits should still be there.

 

It's called DOCP I think for Asus boards.

Where the auto oc would take me?

I'm not a expert at all but this is what i've done that has worked so far.  More then happy to hear critique if need be from other members.

Never used Ryzen but I know the mobo should have an auto overclock feature on it in the BIOS. I'd start out with that since you don't have much experience. Actually a pretty decent OC in my experience. You have the cooling.

I'd say you don't want Auto-OC, it runs way hotter and usually slower then taking a bit of time and finding good clocks for a fixed voltage at 1.325v, or at max 1.35v in most cases.  I'm writing this from perspective you want to use OC daily, in games etc, and not have stability issues, rather then configuring OC for simply gloating about your scores in benchmarks, but having a hot and unstable system. 

 

Start by using Ryzen Master to figure out stable clocks at 1.325v (known safe voltage), or at 1.35v (slightly riskier but 99% should be safe) if temps are fine at 1.325V and you have thermal headroom.  Personally id shoot for max of 75-80C, the cooler the better.  Start by seeing if you can finish multiple cinebench r20 runs while hot,and to confirm OC is actually helping by the score it gives.  Dial back speeds if/when it crashes, then once you think you have highest stable clock speeds attempt a actual stability test like Prime95 or RealBench etc for atleast 30 minutes, you may want to stay with system during this in case temps start going nuclear.  With 3800x its likely you'll see stable speeds between 4250mhz and 4400 depending on silicon quality and your cooling solution.  

Once you figured this stuff out in desktop using Ryzen Master, then you can take those settings and apply them more permanently in the BIOS.


With 5700 instead of Cinebench like with CPU, use Valley or Heaven in backround for initial stability tests.  For starters feel free to turn "Power Limit" as far as it will go, if you plan on creating a custom fan curve do so before you start playing with clock speeds and voltages. Expect to be stuck at 900mhz for memory, its typical with 5700(XT)s they won't go beyond that (occasionally they do but not often.)  For clock speeds and voltage there is a "Auto Undervolt GPU" feature in Global Wattman, check this just to see how low voltage can go at stock speeds and give you a idea what quality the silicon probably is (the further below stock it can undervolt the higher quality the silicon is).  You'll need to use Radeon Global Wattman to find the "auto undervolt gpu" feature, but once you have that as a starting basis for voltage to work up from you can use either MSI Afterburner or Global Wattman.  Some, not many but a few people have had issues with MSI Afterburner on radeon products, but likewise Wattman sometimes has issues of resetting after a restart (i end up with this issue if i launch MSI Afterburner while having a OC applied in Wattman, no big deal) try both if need be and pick your poison, most people prefer MSI Afterburner. 

Start by bumping up clocks 10-20mhz at a time initially, then 10mhz when stability becomes a problem, start at lower voltages, then slowly increase voltage 25mv or so at a time in a attempt to regain stability for raised clock speeds when need be.  Keep at this till card is running too hot or is unstable, try to keep under 85-90C "junction temp", keep memory temps under 95-100C.  Some people will just go for default max of 1.2V and aim for 2050-2100mhz+ clock speeds, but finding lower voltage first even if at slightly lower ultimate clocks is smarter idea as ramping voltage to 1.2V will heat up the card like crazy and turn the fans into a hurricane, and likely isn't good for lifespan of the card either, but if case has good airflow might be just fine with a Sapphire Nitro+.



I'd do DRAM last as it takes the most time and is the biggest headache if you plan to tweak it at all, as 3600CL17 is arguably fine for Ryzen 3000 you may not want to.  So far as memory, like mentioned previously overclocking speed of memory up to 3733-3866 (with looser timings in your case) and pairing FLCK to match it (half speed of rated memory ofc) can have serious benefits if stable, but most people have found stability issues with this when put under scrutiny of more demanding stability tests, and for gaming its usually best to just leave at 3600 speed, 1800 FCLK, and tighten timings as much as possible while stable.  Eitherway a good thing to know is to keep SOC Voltage below 1.2V, and also check actual min/max voltage its receiving in a program like HWMonitor, some people have ran it this high but it likely won't be stable for you and likely isn't good for the CPU.  max recommended about 1.15-1.175V with Ryzen 3000

ya but its fun

Don't forget to make sure you've got a reasonably recent bios revision before you set about trying to find a stable OC otherwise you're back to the drawing board. I'd say start with an auto OC because that will be very conservative and stable, then start tweaking from there.

[claudinho7]

Yeah I will install lastest windows and drivers first create a backup then start messing with OC. I will have more then enough airflow i would say and the only reason i want to OC is because why not? Its amd its competitive and it will slightly increase my performance over some better machines. I will be playing like 5-6 hours a day so I’m keeping it in the safe area but There is plenty of room for  a slight OC and will only help. 
 

Also talking aout airflow, i would like an opinion on my fans config since im starting to work on this in an hour.
