Noob here, with bunch of curiosity, a new addiction. Just a few days only into gaming PC, for the first time ever, I haven't even got the chance to really play games much because this tweaking things feel like some sort of interesting games too

Original build was 6700xt, gpu lasted about 3 days, I wasn't happy with how it performed playing Flight Simulator, so I tried to oc a card that I later knew will never get there. So I got it replaced by the 6800xt, now I am more than happy with the outcome, it's slightly more than what I need.

However, when it comes to benchmarking, this is so far as good as my GPU could go, to get the best score out of Timespy, it ranges between 20.7, 20.8k if I open the side panel for extra fresh air. Just like my CPU, it will score like 0.5% more by throwing some fresher air into the case.

My first question is. When doing Heaven or basically any other benchmarking even furmark, I could set my voltage much lower than this, but when it comes to Timespy, 1060mv is the minimum limit and to keep it safe I put 1080mv on the voltage slider. Basically below 1060mv, even on lower clock for whatever reason it just 'crash', just leave the app for no reason in the middle of Demo. Does anybody experience this and what's the solution?

Also, it's funny how my score actually came down if I run the frequency limit @ around 2600mhz, it’s not that it’s unstable but timespy didn’t push it that way unlike when I do Heaven, the clock goes all the way to 2570mhz when set at 2600. My card is ASUS TUF OC version.

I use 5600x as CPU, 100mhz Auto OC with curve optimiser, runs good enough, more than what I need already.

The set up is as seen in the pic, 32gb ram, alright cooling system. My CPU score JUMPED by 400 points just after I installed extra 16gb, from original set up which was 16gb, yes, nothing else done, I put the new couple of memories on, run the benchmark and boom extra points.


So I wonder, if anyone here could give me any tips at all on how to score a little higher on the Graphic side? I mean, if I could get this score running 2400mhz, I should be able to get 21k mark running 2500mhz if done properly. Or is it because my CPU bottlenecking my GPU by bit?
So the next question I have in mind, I learned that if I could hit that higher FPS on the CPU side, manually OC-ing my CPU say to run at 4750mhz stable, my GPU performance could also be lifted by the better running CPU. Could it be that?
THANK YOU FELLAS!!!


 
Hello guys, I am new to this forum and I don’t have much experience with overclocking! I am seeking your advise, I always had Nvidia but I switched to AMD since I found it cheaper. My system is 5600x with 850 watt psu seasonic focus plus gx, be quiet 500dx, xfx 6800xt swft , Mobo Mai mag b550. What is the optimal settings for 6800xt xfx swft! Max temp 77 celcius
There will be no such best setting for particular model, same card same manufacturer that build on the same day will eventually have different optimum setting. That’s how good it is tweaking your pc, you are your own master hahaha
 
Not sure one could consider this a tip, but anyway, this one is done with just voltage slider at 1080 and mem 2100. Frequency and PL kept intact (default 255W):
And yes, your CPU score seems low due to ... god-knows-why (btw, turn the SmartAccessMemory on)
Our GPU score is relatively the same and sometimes my score get to 20.7-20.8k as well. Updated the pic,

My CPU score range between 8800-9000 max when auto OC up to 150 and 200mhz, and score 8400-8600 on PBO without Auto OC.

I tried Running manualOC at 4.7GHz and it runs very stable at 1.33v but it sets my cpu core v to 1.32 which I don't know if it's a good thing I am not sure what's the voltage limit of this cpu I tried searching but got mixed answers some people say 1.4v is good some said anything above 1.35 is not sustainable so I am kind of not keen to run manual OC, if needed to go to 1.4v to get 4.8GHz.

And what got me curious, as we both get roughly same Graphic score, while you are running at slightly higher clock speed, I wonder how to crack a more stable frequency of this card where we can score that 21,000 even at same GPU clock limit, I saw results where people score 21,000 ++ on graphic while GPU running at only 2335mhz, which somehow I believe it's a very good efficient 2335, and thing must run very quiet and cool too.

my first suspicion in term of that higher gou score that could potentially caused by more stability at higher frequency would be the undervoltage. My card couldn’t get more aggressive at least for now, but I saw people running below 1000mv and still stable at Timespy.

I can do that even playing flight simulator but whenever I go below 1060v, my timespy crash. I am still learning why and I saw several post saying that too it’s like Timespy requires more stability which is good to help setting up gpu tho

Just like I saw results of 9400 cpu score while that cpu only running 4650mhz, how? X_x

I sometimes feel I shouldn't worry about this 2-3% cpu margin much but I am curious hjahaha
 
Like that? (its too hot outside the window, so 9400 is n.p. at night)
man that’s good.. you may also have a good ram to support the good work of that cpu?

because doing nothing but simply increase my ram frequency from 3600 to 3666mhz actually makes my cpu chart more stable and it increase my cpu score from 8700ish to 8900, but I don’t know if messing up with Fury Beast is a good idea it’s a very basic ram I heard

anyway, WHICH core out of those six is your fastest? Per your system and OS

because for me, tweaking for days I figured that my fastest core on this 5600x is the one that can’t be underVolt much hence it cause instability if I force it.

Even when I let the AI tune the cpu CO, it only give -4 on that Core 3. While I see clearly there are cores that can achieve 4850mhz and stable while getting undervolt by -23mv. But that is not the core my system decide as a fastest core.

All these cores were tune all the way to its max frequency and for more than 2hours, the result is, core 3 to get only -4, while as the faster core that thing should get a more aggressive undervolt as it will allow that core to get higher frequency?

and when I run stability test on furmark, that core 3 is also the one that will FAIL first for stability reason if I undervolt all cores equally, even to run 4.6ghz.

i wish I could pick which core is my preferred single threading core but I couldn’t find ways to do that

Fuses rates 4th core best and 3rd core - second best.
RAM is 2x8 b-die running 3800 cl15, though i'm not sure it affects much the CPU timespy score.

Yep, that's usually the case.

There's always two prefered cores in ST and are labeled as 1/1 and 1/2 in the HWInfo clock sensors, but you can make sure of it seeing which cores are active in a CB R23 ST.
That is it, your RAM is the key even before your cooling system man. Basically I oc my ram to 3733 alone and my score jumped by 150 on cpu. And it’s basically low tier ram, kingston fury beast.

And when I set my ram to 3000mhz xmp profile, score drop by 400 points and it can’t have nice graph like my cpu struggling to cope 4.7ghz,

and many people out there wonder why their gpu can’t run stable and blaming the chip, while in most case scenario, a high end DRAM will allow cpu to boost more stable at higher frequency
 
If you want some quick "out-of-nothing" boost in TS gfx score, you can try to disable these features* ** , but I'd fix your cpu issues first and wouldn't underestimate the benefit of SAM in a Ryzen-Radeon system either.
____
*) driver restart always needed after that
**) don't touch other checkboxes, unless you're fully aware what you're doing
i did, forgot to mentioned it thanks for this tip it works good and my gpu runs 100-150 higher score lol.

i only did the smart memory what is that DS thing man? I never use this tool too I installed it once when I was using 6700xt, confused,

I switched my gpu mode from P mode that I got since I bought it, and I kept it that way as it supposed to be ‘performance’, into Q mode, which supposedly means Quiet people said.

all of the sudden, my overclock become much more stable at higher frequency, cooler, and I hit 21k+ Graphic score at 4’c lower temperature.

i don’t know if in my bios accidentally Q means P and P means Q. Lol.




 
I forgot you've got an aib card, which according to TPU has PPT limit set to 272W, and both bioses are differ only in fan settings.
Looks like the gpu just restores correct settings after reset, hence the improved gfx score.

Here is my score with the 270W power limit:
Bro what is aib card and what power limit you got? I kinda scared to change this sort of thing
 
AIB board usually refers to the graphics cards that is not reference design, i.e. cards made by Sapphire (except reference), Gigabyte, MSI, Asus, etc.

The reference design card has the power limit set to 255W by default, Add-In-Boards has it usually set in their sole discretion.
Regarding to changing PL - the driver let you increase it by 15% without any 3rd party tools, i.e. from the default for your card 272W to 312W. And I'd not increase it further on air-cooled boards.
Noted mate,

Thanks..

I still don't understand this Q-P setting. I changed it to Q and my GPU turned completely better, different, I tested it to P, nothing change, change it again and again nothing change, basically one switch that I made, it changed it all I could even score 21,200+ graphic score now LOL, but my PSU is 750w and since then my PSU make some sort of not so good fan noise, like rattling like the fan is losing its bearing or some sort, maybe a 750psu isn't so good for 6800xt + 5600x afterall though it's enough. Try to get this covered for exchange it's EVGA GA, not a bad PSU at all but I think it couldn't handle days of benchmarking d*** hate it. Not a big deal as the noise gone on ECO mode, but still, hate it.
 
I have an Asrock 6800xt OC on the way, what does the 6800xt OC like in general ? I'm aware that undervolting should help these with their Freq-V curve.

I'll need 3x8pin connectors, most PSU don't have that, so I'll need a another patch cable
Why would you need 3 x 8 pins? I thought all 6800xt is 2 x 8. My PSU got 4 slots of 8 pin for GPU, EVGA 750 gold

**I just checked Taichi needs 3 x 8 pins LOL
