Problem at stock with Sabertooth

Hey there,

i just got an Sabertooth 990FX R2.0 and and FX 9370 (just bought it because it was same prize as a 8350)

I got serious problems getting the System run the way i want.

Rest of rig:
R9 290
Corsair 760W
8GB Teamgroup 1333Mhz
SSD 840 Evo Samsung

I'm running on minimal configuration. Nothing else is attached.

Problem: The system seems to run fine when i clear CMOS and let it run on "Default" uefi settings.

However, as soon as I make changes to the UEFI (like setting Overclocking Menu to Manual) I am either stuck with a no more booting System (shuts down after CPU-Led blinked twice) or a System running but stuttering like hell (in Win7 and 3Dmark) with some random shut downs.

Reversing the Settings back to "Auto" won't fix this behaviour. Once the changes were made, the system will continue to run unstable, even if i set it back to the way it was before changes. Only a CMOS clear will make the System run stable.

I swapped the PSU already with an 750W PCP&C Silencer. Same results.

Flashed Bios to 2103 (latest) not any change.

Any input on this?

Remember, I did not even try OC, yet.

I can't change any CPU/Memory related Setting without running into issues. Not a single change possible! I never experienced anything like this before, I really need help. Thanks.

What you do not include in your hardware list is your cooling solution.

Clearly it sounds like something is not correct in your BIOS. How did you flash your bios, please use a fat formatted USB stick and the EZflash2 utility from the tools menu in the BIOS.

Ok,

thanks for opening a new Thread for me.

Thanks for your reply!

So, yeah right. I'am using a AMD Boxed Heatsink. (lol ... I know) CPU wont go over 60° on 3Dmark06.
I intend to use custom watercooling. And custom watercool the Board as well.
But as always, before i do swap any coolers, i check it out "stock" to make sure the Hardware is not faulty by delivery.

I do have an Macho 02 lying around. But mounting that one means taking of the motherboard backplate etc.
As said i wanted to test it "stock" so i did not change anything yet.

If you say i need more cooling i will put on some Fans and my mount the Macho.

But on the other side the System runs flawlessly @4.4GHz after CMOS Clear.

Let me make clear: It had the exact same behavior with the stock Bios. I assumed the stock (1708) was buggy so i flashed the latest 2103. But it didn't change at all.

I flashed using a fat32 stick via the Bios tool EZflash.

The really strange thing about this is the way it shuts down. It just shuts down. No BSOD, no freeze. No restart loop. Just shutting down.
Usually this only happens when Overheat Protection or PSU Protection acts.

But why would it overheat or draw more current by lowering Vcore voltage? Or lowering CPU Multi?

Why would it shut down just because I set my CPU Multi from Auto(22) to Manual 22?

Driving me Crazy.

I will be back home in a few hours. Will Check out a Phenom II CPU on the Board later.

I hear you, one other thing you could check for me is if all the 12 EPS power connectors are fitted. That is one power hungry CPU.

But yeah I do not understand why it takes a clear CMOS each time, hence why I suggest bios update or reflash.

Back again.

I put in my Phenom X6 yesterday.
It runs smoothly. I can overclock it easily on the sabertooth. It runs stable.

So the Board seems to have an issue with the FX. Or maybe the FX is faulty?

I put back in the FX. And Cleared CMOS.

I tried undervolting and or downclocking the CPU in Windows via AISuite. It works.
Trying the same via Bios does not work.

Yes the powerconnectors are sitting right. I Already switched the PSU as well.
All i need is the 24ATX and the 12V 8Pin , right? I don't see any other connectors on the Board. Is there a hidden other one?

Yes it definitely looks like an Bios issue to me as well. Is there something like a Dualbios? Like swapping an jumper or switch onboard?

Or else I should just try reflashing again?

I do have the Crosshair IV. I guess it could handle the FX as well. But Bios Support is not given. As far as i know there is only a Beta-like Bios for FX Cpus. Sadly I don't have another AM3+ Board at hand... I get that bad feeling the CPU might have an issue, since the Phenom ran flawlessly on the Sabertooth..

Use your older CPU to flash the bios for the Crosshair, it will work on the new CPU.

Do the same stuff in the Crosshair that you are trying to do with the STooth and report back.

Sound like either a corrupted bios or CPU...

Hey there.

Today was a new Bios 2104 released. I flashed that one with the FX installed.
Now it works fine. Looks like it was a Bios Issue after all. Glad my CPU works fine 🙂

I don't know about those FX CPUs, but mine looks like a very good sample.
Here some little undervoltaging I did today. 1.225V was not totally stable. But 3Dmark ran.
1.25V should be stable though.
30981

I needed to set LLC to 100% and CPU Current to 120%.
Though LLC 75% and CPU Current 110% were fine with 1.25V as well.
It did not run properly with auto settings for LLC and CPU Current though. So anybody having issues should check those settings.

edit: 4.4GHz with Turbo disabled.

btw: my temps went down under load by 20°C from the lower voltage xD

Very nice mate. You do seem to have picked up a good CPU.
