How can i get the best from my gigabyte b550 x v2 motherboard and amd 5900x cpu

[paulwarden]

hi guys i want some advice on how to get the best out of my mobo and cpu at present the cpu is running at 4300 mhz and i would like to get the best i can from it .i have tried using amd ryzen master and am finding it hard to get teh best from my cpu

 

[P4-630]

How hot does the CPU get during a 10 minutes Cinebench R23 multicore run?

 

[paulwarden]

it gets around 75 to 78 c

by the way i am using a watercooler to cool cpu it is the corsair H100 cant remember which one it is though

 

[GerKNG]

curve optimizer + clock offset.

When does the CPU run at 4.3GHz? This CPU should usually run anywhere between 3.2GHz up to 4.8+GHz depending on load and temperature.

 

[paulwarden]

i set it to run at 4.3ghz manually also i have no idea of how to set curve optimizer +clock offset

 

[Zach_01]

Why would you do that manual 4.3GHz set when you can have it run up to 4.8+GHz when it can and when its needed?

Also what voltage you set for 4.3GHz?

 

[paulwarden]

i had no idea it would do that last cpu i had was the amd fx 8350 so will give you an idea of how well i know whati am doing lol

the voltage is at 1.2v

 

[Zach_01]

Ok you should forget what you know so far from previous sockets. I too had a FX8370 until 2019 and AM4 with a Ryzen5000 on is a completely different platform.

Return everything on stock, keep PBO to auto or disabled (its the same) and download

1. HWiNFO64 (run sensors mode only)
2. ZenTimings

...and let us see what you got there

 

[paulwarden]

how can i copy them s you can see them

 

[Zach_01]

Alt+Prtscr and paste here each window

 

[paulwarden]

figured out how to do it correctly at last

 

[Zach_01]

This needs a little work...

You can add more columns on HWiNFO to make them 3 or 4 so you can see more sensors at once without scrolling.

Your DRAM is a 3600MHz XMP kit (2x8GB) and you have it enabled, ok. Its on stock XMP and this can be tweaked a little for better memory results.

I can see you CPU clock up to 4.95GHz but that can be a fake because I forgot to tell you to set HWiNFO on "Snapshot CPU Polling". Right click HW system tray icon, settings and enabled it

One matter that needs fixing is that low UCLK clock speed. Its the memory controller of the CPU and runs the half the speed of what it should be.
In your BIOS on Tweaker page you'll find it
UCLK DIV1 MODE and you set it to UCLK==MEMCLK

After this all speeds MCLK/UCLK/FCLK will run at the same 1800MHz. This will be the 1:1:1 ratio and its the best for higher performance and low latency between CPU<>RAM.

Do you have the latest BIOS for your mainboard?

 

[paulwarden]

many thanks

i am using the latest one as far as i know

 

[Zach_01]

Did you set UCLK==MEMCLK? Did it work?

There are a lot more tweaks that can be done. It will depend on how far you want to go on the CPU and/or DRAM settings.
Your cooler can play a role on how far you can get on the CPU.

Also one matter is what you need/want more. Better gaming performance or multithreading performance like rendering, editing and such? Or maybe you want to score higher on benchmarks?
You can set the CPU to clock higher, potentially up to 5.150MHz but that will hold back the multithreading clock.

These CPUs clock the highest on single or middle threaded loads and somewhat lower on multithreaded (100% load) situations, somewhere between 4.0~4.2GHz when on stock settings.
Of course you can set it with PBO+Curve Optimizer to do higher clock on both single threaded (ST) and multi (MT) loads. You can do a little bit of both or choose the one against the other.
We can come into that once you get familiar with what you have in your hands now and how it works in general.

For example the way I set (a 5900X also) it boost up to 4.9~5.0GHz and on 100% load it sets boost around 4.3~4.5GHz depending the type of load.

To get the MOST out of your system, add a M.2 gen 4 drive to the compatible slot (your mobo looks to have 1 gen 4 slot and the other is a gen 3). Either get a big one and use it for games and os or get 2 and run the os from a gen 3 drive and games from a gen 4.

Coming from fx 8350 is a big jump, the new overclocking is undervolting as has been mentioned it's a case of tuning and testing the cpu with voltage curves and PBO boost to get the most out of the cpu. Some people can't boost with PBO at all with certain chips but the norm is most people can benefit from PBO.

In bios you set a +200mhz offset and then you can either set a single negative voltage for the whole chip (a -5 all core should be completely stable) or for more advanced option you can tune each core manually and use P95 to test whether or not the system is stable with each adjustment. P95 workers 1 and 2 are core 1, 3 and 4 are core 2 and so on so if worker 7 fails on core 4 you need to give that core or the adjacent cores more voltage.

Use TestMem5 to check if your ram is stable as it will give errors if there are any problems. I recommend a 3 hour stress test on P95 and the same with TestMem5 to test for stability, because either your system is P95 stable or it isn't. P95 will generally fail workers in the first few minutes if there are any issues.

For example the way I set (a 5900X also) it boost up to 4.9~5.0GHz and on 100% load it sets boost around 4.3~4.5GHz depending the type of load.

And this is without exceeding the stock limits of the CPU.
Settings of PBO+CurveOptimizer+Boost override can have many different combinations to achieve the desired outcome.

A 5900X has power(draw) and current(Ampere) limits set by AMD

PPT (package power tracking) : 142Watt
TDC (Thermal Design Current) : 90A
EDC (Electric Design Current) : 140A

PPT and EDC are the most important.

Of course you can set these limits higher (PPT mostly) by a little or by too high. Its up to you to decide how far you want to go. As I said your CPU cooler plays the major role for PPT (watt). Because power consumption is translated into heat that you cooler needs to dissipate.

Its good advise but first he needs to know what is what and whats he is doing and for what reason.
We can all give him settings to copy/paste. Personally I dont think its the best way.

BTW the system already has an NVMe drive but I cant see (the name) if its PCI-E 3.0 or 4.0, but that its not really a matter. Its already fast enough even if its 3.0.

 

[paulwarden]

my pc has 2 NVME drives one is PCI-E 3.0 the other is PCI_E 4.0 the 3.0 is a 970 evo plus the 4.0 is WD black sn 850 and now i have lost access to the 2 1tb ssd hard drives

After what change you've lost the two drives?

 

[paulwarden]

after i set the UCLK==MEMCLK

i have sorted it myself turns out i had hit the wrong button on my set up and had to change the setting in bios

So now its fine?

Any questions about CPU/board/RAM so far?

B550 chipset may have some limitations on PCI-E when you have multiple NVMe drives. Check it like below if everything runs at max speed

And please fill your system specs with as many system details as possible here at forum. Set it as visible from other users so we can all see your specs and wont have to ask every time.
See mine below my avatar to get an idea.

XMP spec was read incorrectly by GB, tRC should NOT be 84 (should be around 58). Run CPU-Z and check the SPD tab.

 

[paulwarden]

for some reason i get tRC84 when i use ZenTimings and 58 when i use cpu-z

PSU?

XMP spec was read incorrectly by GB, tRC should NOT be 84 (should be around 58). Run CPU-Z and check the SPD tab.

Its typical I guess for Gigabyte boards as the have 3 separate different levels of XMP (as profiles). When its on Auto it must set secondary timings looser. I never got into that and always set all timings manual.

ZenTimings shows current settings.
CPU-Z on SPD tab just shows the JEDEC/XMP SPD. If you click Memory tab you will see the same with ZenTimings.

You can set timings to better/faster settings in BIOS. I can show you if you want as your BIOS configuration should be the same with mine.
