3800XT: How do I get better performance

[mrdoubtfull]

Hey guys! 

 

Just wanting to compare and get any tips on my setup.. 

 

So I grabbed a 3800XT off a seller on OfferUp, that's never been used, for less than a 3700X new. Hoping to replace it with a 5900X

 

I'm pairing it with a B550 Gaming Carbon for now until my X570 comes in (B550 is going to fathers build). 

 

Just wanted to know if my r20 scores seem normal.. SC is 529 and MC is 4960. My 10700K at 5.1GHz did around 5100 MC (never did single core).. I also got an average voltage of 1.350v during Prime95 after 10 min. 

 

I have PBO enabled and a few other settings adjusted but I'm not really familiar with AMD.. This site has better single core.. https://www.guru3d.com/articles-pages/intel-core-i7-10700k-processor-review,8.html. 

 

I'll definitely be overclocking my memory.. 

 

My full specs are:

3800XT

B550 Gaming Carbon WiFi

4X8GB Trident Z RGB 3200c14 B Die

2080 Ti Hydro Copper

RM850x

Custom Loop

is your ram running at the correct speed (xmp enabled?)

With PBO enabled you're probably getting close to the max performance you can anyway. A negative voltage offset to reduce temps and increase clocks a little may improve performance slightly but the custom loop is probably doing a lot for you

I enabled XMP but I definitely need to overclock it higher and raise the Infinity Fabric.. Just got done putting it together last night so I'll play with it today.. 

 

I'm curious about overclocking each core seperately, is it worth it? PBO with custom settings gets up to about ~4.55GHz.

Any special settings for PBO? I don't remember the names of the settings but I did PBO manual and changed scalar to 10x and limits to motherboard and +500mhz for max boost, LLC set to 4.. I didn't test the auto PBO settings. 

 

The loop is keeping it pretty cool, I think it was 60C on prime95 after 10 min.. So it's definitely helping! 

 

I'll try the voltage offset.. Any particular voltage I should start with?

Not sure about your situation, my 3700X definitely got a boost from an all core OC, but idk about your chip

In Ryzen master you can raise the EDC and PPT limits might give you some extra boosting. That will depend if your near limit while under load, but something you can play with.

Did it affect single core performance? I tried 4.5GHz all core and got the same r20 multi core score as just enabling PBO.. I'm gonna play with it more today and see what happens..

Thanks, I'll give Ryzen Master a try!

That is a little low. I got ~4500 on my stock 3700X, ~4700 on my 3700X PBO, 4970 on my 4.2 GHz daily driver OC, 5003 on my 4.3 GHz unstable OC with super high temps.

I guess it lowered it by 6 points, but my particular chip is pretty average in terms of silicon quality so your XT chip could probably keep the same (for me it made no difference practically)

You can do 4.5 all core? Run prime95 test stability (voltage under 1.325V static and lower than 1.3V that under load with Vdroop, mine drops to 1.206V under load) and if it is stable, run that!

How do you change vdroop? LLC? I think I can go higher than 4.5GHz on at least some cores which is why I want to try overclocking cores seperately instead of all core.. 

 

So you got over 5000 with 4.3GHz? I should be able to do that so that's weird.. During r20 with PBO enabled it clocked down to like 4.2GHz but with the all core overclock I still got the same score so something is off. Maybe it's showing 4.5GHz and running at something else? Prime95 it ran at 4.4GHz.

Yeah. I use LLC3, but you don't need to change it if the Vdroop is already within your target range. Is this OC prime95 stable?

On Zen 2, you can only really OC per CCX. For me my better CCX has one bad core so it isn't worth doing per CCX

Honestly you are probably fine. My friends 3700X with the exact same CCX quality numbers (reported by CTR) gets 5048 with the same unstable OC as me

It was stable for the 10 minutes I ran it lol. Haven't had time to run it and I had a leak last night so wasn't wanting to chance running it while I slept..

Ahh ok, I'll play with this a bit..

Gotcha, I'm gonna play with the RAM settings and see if it helps..

Haha I only tested mine for 10 minutes, saw no thread usage drop down. I might test it for longer someday but honestly 10 minutes with no usage drop could be enough (maybe, not in all cases), at least in my case. My two unstable OC tests crashed within the first five minutes

I'm going to do this as well. RAM has a big affect as you know for sure

Exactly, mine usually crashes pretty quick as well lol.. I've actually had overclocks that were fine for gaming and everything I ever do but once I ran prime95 it would crashed haha..

I used this as a starting point, but the OC wasn't 100% stable. It gives a great idea of how good your chip is tho!

true however, i checked your profile. it shows nothing about your cooler? are you using the stock cooler? also keep in mind. your case is horrible for airflow. which would reduce oc headroom cause of temps.

you can always read the guide maybe set a limit to how far you will let it go.

yeah, but temps are okay (70c in CB). Problem is one core on my strong CCX, CTR's OC is only unstable in p95
