System at stock not stable

[IVIYTH0S]

Did you try lowering your CPU's main multiplier??

[DanTheGamer11]

Lower than stock 2.8ghz? No, what would be a good value? x10?

Just one or two clicks down from what you're at

I assume I have the 95W since CPUz says TDP is 109W with TurboCore on and 101W with it disabled.

 

Uninstall HWmonitor, CPUz and the asrock thing?

 

*Edit*

 

I don't see the option to modify the NB voltage or the NB/CPU voltage, just a chipset voltage from 1.262 -1.344V

You can leave HWMonitor and CPUz installed.  Just uninstall the ASRock OCTuner as we are making changes manually in the BIOS and don't want the ASRock OCTuner conflicting or over-riding anything.

 

Also, for consistency sake, please download CPUz version 1.54 and use it instead of the version you're running right now.  I've got some old benchmark results from a 95W 1055T and I was using CPUz version 1.54.

 

Open up CPUz then fire up Prime and capture a CPUz screenshot of your cpu voltage under load.

 

I need to know what your cpu voltage is under heavy load.  From the pictures above it looks like your cpu voltage is dropping to 1.20v under load.

 

I pulled a copy of your owners manual, and you're right, there aren't many voltage control options available.  That is unfortunate..................

 

When grabbing CPUz screenshots, please share pics showing the CPU tab, the Memory tab and the SPD tab.

 

Thanks.

Theres tools out there to record voltage stats as well as temp stats when testing, it sounds like it could be the psu dieing to me.  I would keep a close eye on your 5v/3.3v rails and see if they dip under load could easily drop down for a second under heavy loading of prime.

@ Wev,

Do you want me to put the voltage control back to auto? 1.2 was the stock voltage when on auto, atm it's 1.35 from yesterdays test.

 

@ confuzzedintel guy

Any recommendations?

 

Also, what Prime95 version should I use? The latest one 27.9 displays 'optimized for K10 architecture' whereas 25.7(I think) doesn't

Dan, any version of Prime that supports multi-core testing is fine.  Pick your poison  

 

Manually drop your cpu voltage down to 1.25v

 

Manually set your chipset voltage to 1.31v

 

Don't forget the CPUz screen shots once you start your torture testing  

 

Do you have a digital multimeter?

[DanTheGamer11]

If you mean something like THIS then yes I have one! What do you want me to poke with it

 

I guess I'll continue using 25.7 since that's what I've mostly been using so far.

 

Gonna do that now.

Yes, the Fluke is perfect.

 

First find open leads to the 12v, 5v and 3.3v rails on your power supply.  We are going to measure the voltage rails under load and confirm that they are within spec. (might help identify a faulty power supply).

 

Since you have a Fluke I'm going to assume that you know how to measure voltage  

 

Each of the three voltage rails should be within +/- 5% of the nominal value.

 

If you're unsure how to identify what wires are what (or even how to check the voltage rails) there is a very good guide here;

 

Testing Your Power Supply Voltage Rails

[DanTheGamer11]

Do you want the values that HWMonitor gives for 3.3,5,12V rails too?

[wevsspot]

Not needed Dan.  You might want them for future reference, but the multimeter measurement is going to be the most accurate.

 

Did you buy the motherboard and cpu new or used?

[DanTheGamer11]

Mobo new, CPU used
