7800x3d- how to optimize?

Posted by Blackbeard516@reddit | buildapc | View on Reddit | 15 comments

Let me first say i'm new to this and just recently built my first gaming PC. I read to turn auto overclocking on so i have that enable in Ryzen Master. My cinebench score was terrible. Then i saw to turn OPD on. SO now im not sure what to do.

Can anyone provide some advice on what i should turn on to optimize the processor

I have a b650 aorous. 32 gb ram and 4070 super. ANy help would be apprecited. Thanks

Wow so much wrong info here and you can see clock stretching using hwinfo and watching the core clocks vs the effective clocks while doing cinebench tests. If you have 100mhz or more difference you are clock stretching. Curve optimizer only causes clock stretching if you use extreme values that your cpu is probably not stable with anyways. Cinebench also isn't a good stability test for curve optimizer anyways as you can run stupidly deep values and still pass the test but then go do a ycrucher vt3 that will reboot your system instantly. Also the only way to oc the cpu clocks is to use bclk or eclk if the mobo has that option and there is benefits to doing so just takes time and testing to get stable. Just riding stock and using garbage expo also is outdate advice as expo is garbage learn how to tune ram if you want to get the most out of the cpu. If not run expo sure or better yet find out if your ram is hynix a or m die and use buildzoids easy timings for 6000 which is still much better than expo. There are lots things you can do to also get better performance out of the cpu but will take time and testing to get just right.

STOCK:
The main advantage of the 7800x3D is its STOCK _PEAK_ GAMING PERFORMANCE.
EXPO ENABLED
You dont have to do anything but enable EXPO with your RAM. Ideally you want DDR5 6000MT/s CL30 RAM, but if you got something slightly slower - it doesnt matter that much, thats another main advantage of the X3D, that the cache scales a bit less with memory OC - less gains with ideal memory.
NO CPU OC
Don't fool around with manual OC with the CPU. Manual OC with AMD CPUs is BAD FOR GAMING, because its about all-core frequencies that will be lower as what you get with the STOCK PBoost.
Curve Optimizer (JUST DON'T)
first and foremost, it doesnt do anything for gaming performance
HERE IS MY 7800x3D with a higher as average bin quality

- nobody is posting CO performance metrics, because it shows clearly if it works or not in Cinebench
- this are back-2-back CB runs with a basic AIR cooler (Noctua D15)
the average 7800x3D wont benefit from it, not even in CInebench, but it will trigger AMD's Clock Stretching, a hidden / blackbox feature that triggers if the CPU detects STUPID / UNSTABLE MANUAL SETTINGS and DOWNCLOCKS / FREQUENCY THROTTLES the CPU => less performance and slightly less heat
IF people mention lower heat, lower temperatures with CO without touching power limits, it means their CPU is not good enough and it gets DOWNCLOCKED and they dont even realize it, because they dont test for performance as recommended

TLDR: keep the CPU at stock, enable EXPO with what ever memory you got and ask OC questions in dedicated and moderated forums and not here at reddit, you get just trolled.

thank you. I reversed the OC. One thinig im curious about is ryzen master has several profiles(creator, game etc) in advanced settings which is the default, i had switched it to profile 1. Might be a dumbass question but here we are. THanks for your write up!

I am about to get a ryzen 7800x3d, so how’s the undervolting and OC going? Did you decide to keep it stock?

I’m interested to hear how stock is better? I did a -30 Curve optimizer and got an 8% boost in R24. I also ran occt multiple times for over 2 hours with 0 stability issues.

Edit: I saw you had replied and had some useful information on there when I was reading it! I’m not sure why it was deleted. I had this reply though.

Thanks for the tips as I’m new to doing any sort of OC/UC. I have played a number of games as well as running the pc for work for >8hrs a day and have not had any stability issues but it’s only been a few days with the CO adjustment. I can see the boost clocks are hitting above 5100 during gaming so they don’t seem to be down clocking the boost for single core in any way. Temps are the same before and after CO but that was exactly my intention. I’m using a 360 aio for cooling so doing the CO may work better with the cooling solution I’m using.

I deleted it myself. I did not have time to edit it to be more readable. Its the wrong sub for it either way, r/buildapc is about funny one-liners and random partpicker suggestions with no comments.

btw. CLOCK STRETCHING is something you need to read up with RYZEN CPUs. Its not visible with sensor / frequency data, thats the whole reason why UV / CO is to be MEASURED with Cinebench metrics, to see a GAIN / LOSS, since AMD keeps it as a blackbox mechanic.

This is 7+ year old stuff in OC forums. A good forum search should answer all your questions, to sources, tests, recommendations and basic understanding to what OC settings do, what the CPU does and how you can verify your results.

So do you still enable PBO but keep CO off?

[-]

lichtspieler@reddit

No PBO since the last AGESA update since there was no measurable advantage anymore.

With Win10 KB5041582 / KB5043064 and the RYZEN improvements, it would also require a full stability retesting marathon.

Right now its gaming season, so I keep everything at stock.

hello just passing by reading reddit, I had my 7800x3d for a few months and I never seen a single clock goes above 5000, I had pbo and -30 offset and stuff setup does it means im losing perf and i should revert all that because ive read 5100 in above comments ?

I'm getting 15032 at these settings. I don't understand why it's so far off yours. Any suggestions?

blinkt1988@reddit

Is this still work i have 7800x3d and rtx4090 and ddr5 64gb cl30 6000mhz i really want get good performance but with not a lot heat..What i do is enable pbo set curve all negative -20 or -25 i not remember right now...i enable expo..and set manually ppt 85 tdc 75 and edc 150 is there anything what i can do more

What score did you get in Cinebench R23 and 2024?

[-]

Blackbeard516@reddit (OP)

i reran it after changing settings and closing apps i had the first time up. it was 17767

[-]

stefanels@reddit

I'm using THIS SETTINGS on my 7800X3D , and getting THIS SCORE in R23 and THIS SCORE in 2024 (temps to)

I know it's been some time since your original reply, but your PBO settings (PPT: 88W, TDC: 75A, EDC: 150A, Thermal Throttle: 85°C) are quite conservative compared to the default limits for the 7800X3D.

PPT (88W): This could limit the CPU’s ability to boost fully, especially under heavy loads.
TDC (75A): Similarly, this might restrict performance in multi-core scenarios.
EDC (150A): This is generous and should handle peak current demands well.
Thermal Throttle (85°C): Keeps temps low but may throttle performance.
Have you made any changes since then? Personally, I have the CO set to -30 on all cores and PBO set to ON.
