I finally got my 8350 up, whats the stock volts for this thing running in turbocore?

# of P-States 4
P-State FID 0x1A - VID 0x0A - IDD 13 (21.00x - 1.425 V)
P-State FID 0x19 - VID 0x0C - IDD 13 (20.50x - 1.400 V)
P-State FID 0x18 - VID 0x12 - IDD 12 (20.00x - 1.325 V)
P-State FID 0xFFFFFFFF - VID 0xFFFFFFFF (-1.00x - -1.000 V)

Get a dump from CPUz, you will get an idea on the volts the CPU will use for different clocks.

Swami has the right idea. The FX CPUs "stock" VIDs are all over the place and very CPU dependant. If you leave your machine at defaults in bios you can get the P-States from CPU-z. Open the software goto the about tab and export to .txt file. In that file you'll find something similar to what Swami posted. There's a lot of info and you'll need to scroll down a ways.

I was thinking of running the cpu at 4.2GHz at all times without the turbocore i guess 1.425v

I also have my ram running at 2133 1.6V and 9 11 11 31 as per on ram.

Most of the time the CPU can run at 4.2 with 1.35v or less. Turn off turbo and set it at 4.2, start the voltage at 1.35v and work your way down.

I had stability issues at 4.4, no time to tweak, so left the machine at 4.2Ghz with stock non-turbo volts (1.325v).

 

[eidairaman1]

Im not worried about running at minimum voltage just at factory spec. The cpu stock runs at 4 with 1.368.

I wont be ocing per say atleast not for 6 months.

 

[Johan45]

Depending on your CPU that 1.425v may be good enough for 4.5 as long as cooling is sufficient.

Peer at my specs and tell me what you think.

With an air cooler 4.5 is going to be near the end of your cooling capabilities unless you have a very nice CPU on your hands. I would start with 1.4v and see how far that gets you. I'm not familiar with that coolers capabilities

 

[eidairaman1]

It was reviewed here, same with the gpu and power supply.

90cfm fan on cpu, 86 cfm for the 140 mm fans 6x, 156cfm for the 230 mm fans 2x.

Sounds like you have lot's of airflow, that's good. As for the CPU max and cooler , it'll really depend on "your" CPU. I have seen some that max at 4.5 with a hyper 212 and others with the NH-D14 couldn't go any higher but some reach 4.7-8 . You have to do the testing and keep it within it's thermal limits About 65c for the core and 70-75 for socket depending on the board. The Sabo is pretty tough. If you find you have a big discrepancy between the socket and core temps like 15-20c then you'll want to add some cooling directly to the VRM and back of the mobo. This can drop socket temps up to 10c

If you only plan to run at factory spec (volts), then just turn off turbo and increase multi to 21 and you should all be set.

Do you use 'S3' sleep state? If you use some boards don't like with certain settings like mine, I have to leave LLC to Auto, if I change it to anything else even at stock 4 Ghz I see black screen. I have been chasing this issue and found a thread on another forum who had same issue like me and posted this solution.

 

[eidairaman1]

I dont have an os installed yet, i havent dived into any apm in the bios, only thing ive set to default is the htbus at 2600 the fsb at 200 and the multiplier at 20, ram at 2133 with 9 11 11 31 1.6v, core enable/disable.

I guess the board/cpu needs that extra boost that the llc provides for "wake" function. Nice find Swami

Once you get it up and running there's lot of little things you can tweak here and there. If you like to keep the power saving options then I suggest you use offset voltages. That way when you're idle in OS it'll drop V_Core and CPU speed when surfing.

Im just glad i didnt need a diff gpu to fire it up, i will be disabling pci e link state so it doesnt droop. And run it all at 4.2GHz. Apm is not fool proof and 100 percent and thats why so many have issues with gaming.

I think you need to enable HPC if you don't want your CPU clocks jump around during load (I might be wrong, I get confused with APM always).

 

[eidairaman1]

Yeah your bios is diff than mine...

 

[Johan45]

I have the sabo and CHV-z and I leave APM on auto and enable HPC if I thought it was throttling me I'd disable it but I kick the crap out of these FX all the time and haven't seen it yet. The sabo is a good stout board eidairman you shouldn't have anything to worry about.

 

[eidairaman1]

I read this here, any truth behind this?

http://www.ronwoods.us/2014/02/what-does-amd-application-power.html?m=1

Yeah i read up for Amd 5ghz and this board came up.

I almost had second thoughts on my video card due to the size and almost traded it for a msi gaming or xfx dd card. But im gonna keep it. I might wc IT

 

[Johan45]

Yes it's all true but to overclock you have to go outside the TDP design of the mobo and CPU. These settings allow you to do that outside those specs. Some boards are better equipped to hanle it than others. The Sabertooth ha no issues with that so no need to worry. I ran my 8350 up to 5.8 no issues with the right cooling. Probably had my chip using 300 watts before.

 

[eidairaman1]

Ok i will just be upping the core to 4.2GHz. Turbocore will be off. Hpc on and apm off?
Should I reapply my tim as a bb size ball in the middle? I initially used a old credcard spread like AS5. Heres my bios screenshttp://www.techpowerup.com/forums/threads/new-gaming-rig-amd.195936/page-9#post-3177139

 

[TRWOV]

Build finished.

Kneel before my mighty CM

Testing RAID:

 

[Pehla]

hey guys ...,just want you to know that i made my cpu run at 4.2ghz and memory at 1866mhz..
Cpu v.core at 1.4v/memory at 1.65v(didnt try to lover memory voltage)
i dont know what i did wrong before but my pc was unstable like hell...,random restart every now and then,but now its super cool...
i was even thinking to change motherboard soon,but im holding to this one for some time...
Happy OC to everyone!! free performance

 

[eidairaman1]

Yeah thats the thing about ram its best to run it at its recommended clock, timing and voltage to avoid problems. My rig will be at 4.2GHz eventually with the ram at 2133.

@TRWOV Looks good !
@eidairaman1
When doing TIM on these FX they have a pretty big IHS so a BB size would be a bit small IMO. I use a pretty good sized gob.
