New AMD Kit arriving need a bit of advice

[ade555]

I was on and off about buying ect for a while, like most waiting for prices to drop or something but finally bit the bullet and have few question, mainly towards motherboard, settled for Asus Rog Strix B650 E-E board and Amd 7800X3d, last time I used AMD was when Athlon come out, yep that long, I know my way round bios and their settings in Intel but AMD is foreign territory, does anyone know if Bios needs to be updated for that CPU or anything? also intresting to hear if there is certain settings in Bios that works better with AMD 7800x3d.

Will be cooled with Artic Freezer III 360 and notice on manual you have option for all in one cable or three seperate to control pump/fans/ vrm fan - which option would you choose? looking at the manual board have enough connections to go separate route, was thinking about this mode if the little vrm fan is to loud or something so I can adjust if is a option
1 x 4-pin CPU Fan header
1 x 4-pin CPU OPT Fan header
1 x 4-pin AIO Pump header
5 x 4-pin Chassis Fan headers

Also intrested to hear from anyone who is using the same AIO for 7800x3d.

Thanks

No, it should boot out of the box.

Make sure it has a BIOS new enough that it covers the fixes from the burning issue (which caps the SOC voltage), especially prior to enabling EXPO, but I'd be surprised if the stock BIOS was that old.

Looking at website looks like they implemented from bios 1413 then got some beta and I just presume here 1616 was the last one they mentioned this SOC, then there is 11 newer versions from then on and no further mentioning about SOC, so anything above 1616 should be good

ROG STRIX B650E-E GAMING WIFI BIOS 1413

Version 1413
9.16 MB 2023/04/27
SoC voltage for Ryzen 7000X3D series limited to a maximum of 1.30V to protect the CPU and motherboard.

ROG STRIX B650E-E GAMING WIFI BIOS 1616

Version 1616
9.19 MB 2023/05/16
"1. Update AGESA version to Combo AM5 PI 1.0.0.7.a
2. Support 48/24GB high-density DDR5 memory module.
3. Memory QVL amended to account for AMD 1.3V SoC voltage limit.
4. EXPO/XMP prompt notice removed.

Before running the USB BIOS Flashback tool, please rename the BIOS file (SB650EE.CAP) using BIOSRenamer."

Be prepared for memory training on first boot. There is a BIOS setting to prevent the training on every boot. There's a thread somewhere in the memory or motherboard forum.

Just a had quick look on Asus website and looks like You need to enable EXPO and subsequently enable Memory Context Restore, Thank you for the heads up regards this as I would panic at boot

Also read up on the PBO settings. I tried tweaking but left on default. I don't game so CPU (7950x) rarely gets near 100% util.

I will be mainly using for MSFS so will take a look but at first will try default been honest, PBO is that about under volting ect.?

No Internet connection, but found solution on net, only strange thing was I had to run batch file first then restart otherwise I was getting error driver not supported for this windows.

Just to add I'm actually connected to LAN.

Is this common on AMD or is down to motherboard manufacturers?

 

[ade555]

PBO is overclocking. Let's the CPU boost at higher frequencies. I've only used Curve Optimiser to optimise the chip (undervolt). You can install Ryzen Master and let it do it for you. Takes like 45 mins or so to run through. You can then take the value and hard code it into the BIOS if you like.

How To Use The AMD Ryzen Curve Optimizer - thinglabs

AMD Ryzen processors are well known for their top performance, and now users have an extra tool to fine-tune their systems: the AMD Ryzen Curve Optimizer.

gadgetmates.com

I have seen video regards this somewhere, will need to take a closer look in coming day or two.

 

[ade555]

Installed the AF III with separate connections, board has plenty so why not.

 

[ade555]

I need your help, windows installed, all drivers updated, latest bios.

Enabled Memory Context Restore and once in windows about 30 sec later I get blue screen Memory_Managment error.

Was on Auto, post screen in35sec full windows about a min, once changed to enable yeah 14 sec in to post screen then I was in windows at 36 sec. Fair bit difference but blue screen

 

[ade555]

I found the problem now, there is 2 settings that needs to be changed, Context Memory Restore and Power Down or something like that, works fine now, ram running at 6000 and also went with Negative 20 on curve optimizer, will run like that for now then see how it can go bit higher on it

 

[ade555]

Well I almost forgotten this turned out OK for a simple build, wasn't bad attaching the Artic to mounts, not sure what all the fuss is about when you read online, as I don't see the case is budget friendly Montech 903 Base and in all honesty is not bad, was expecting worse for that price, still waiting for my corsair 600w gpu cable so should arrive after bank holiday and I am very impressed with preformance of that build so far.

 

[ade555]

So had a little time to go over phew things and not going to lie I don't like the fans that are on that AIO, pump is very quite but god them fans sounds like jet plane when they spin up, anything over 65-70% I'm not experianced enough regards AIO but had some artic fans in pass for case that I quickly removed due to noise.

What would you recommend it? In 120mm department

Need bit of advice regards this PBO: originally had -20 all cores then decided to try negative -25 when running cinebenchr23 I get 18177, looking at how the cores boost in Hwinfo this will very from 4040-5050mhz. Temp peaked up to 89c max, I could be wrong here but don't thing that's how this should be?

Decided to go back to -20 and results ware 18233 with all core not less then 4850-5050mhz, temps 84.9c max


Would this indicate that -25 all core is bit unstable? No crashes. Shouldn't negative 25 offer better temps ect.? Gaming wise temps don't go above 60-62c will get occasional spike in temps when opening program while game is running but this is to be expected.

If I'm correct I would have to take a look at finding the correct figures per core instead all but will await your replys.

 

[ade555]

well set a custom fan curve in bios that doesn't let them scream? They are still good for noise/perfomance, just set up for higher speed in LFIII

lower curve allows higher boost at same volt and that could result in higher power and temps
To get better temps you need to combine it with temp or power limit

But the cb score should not be lower, recheck

Fan curve is set but I do have them to ramp up incase cpu hits 80c, away from PC to actually tell you what they set at currently. Usually it don't trigger as temps run under 70. Don't know if I should drop the fans speed to max 65-70%

Regards all this PBO volts and temps when running -25 under multicore CB I can see the cores jumping from 4040-5050mhz when in -20 they steady with 4850mhz on all and max that I will occasionally see is 5050 per core but never lower then 4850, all this is bit confusing, where -25 will result in cores dropping to 4040 at times, and wonder if this is normal behavior. Once I get home this evening I will re-run CB and post results having figures reset on hwinfo, also I'm sure I seen voltage of 1.145 max on core

I hope this makes sense

 

[ade555]

Here are the results running @ -20 so managed to get bit then last night actually, only thing is I'm on Windows 11 not windows 10 not sure why it says that, version R24 says 11

 

[ade555]

-25 Results

 

[ade555]

I had bit to much time on my hands this morning and decided to take a look at individual cores using first ryzen master then manually adjusting in bios. Cores ranging from -43 to -48. I tought great, run R23 on single and multi, with score of 18996 on multi. Then started a game that's where my fun has ended.
So where am I going wrong or is this ryzen master all bolloks? Giving this under volts is it to much? Returned back to -30/20/10 on all cores and is all back to normal. I can do any task if I set the cores individually apart from flight sim. Am I missing something?
When run r23 I kept eye on temps and clock speeds.
I'm trying to understand why more then anything, I stumble across a post sometime ago this could happen when load on cpu is to low but not sure if is accurate info.

 

[ade555]

Yeah, 43 to 48 is way higher than I've seen anybody run on here, I think 30 is considered decent.

Is not crashing when running ryzen master so I set them core to figures that I could test to max. Interesting thing is when you load flight sim and is heavy for cpu for a while everthing is fine until load on cpu drops off. Still just crashing back to desktop no black screen or blue, just shuts the game. Will have to try maybe on something else perhaps to see if same behavior?

 

[ade555]

I don't understand this stuff in detail, but from what I'm aware, with the curve optimiser it is not uncommon that instability is most strongly exhibited at low load instead of high load, due to how the curve optimiser is like an offset of the frequency/voltage tables and it gives you a relatively low idle/light load voltage for the CPU, which it may cope with worse than having a lower voltage at high load (though, without a power limit it will also increase the max boost frequency and the voltage along with it).

This behaviour ^^ can also be impacted by the motherboard.

I'm not expert by any means and is steep learning curve for me with amd, so thank you for your input. Just thinking out loud here, this would indicate that the voltage is to low on low cpu usage? Could this be somehow set under low usage voltage don't drop below certain figure?
