Re: ASRock 990FX Extreme9 sleep mode causes cpu performance loss.

First, your 7-ZIP benchmarks show two passes for the first one, and one pass on the second one, if that matters.

But your benchmarks show significant differences. IMO, your focus should be on the CPU, not on the Windows sleep state settings. FMI (For My Information), what is the purpose of, settings, what was that intended to do?

Are you using anything to monitor CPU performance during your benchmarks? Such as core speed, if all core and thread operation is the same, before and after Sleep mode. It seems like all the cores are not functioning, and/or not operating at their full speed.

The free program HWiNFO64 displays each core's clock speed, and the amount of core and thread usage, and is constantly refreshed when it is running. If you don't have another program to do a similar thing, give it a try.

Just something I tried to see if it affected my cpu performance after coming out of sleep state.

I tried the utility you linked. Thanks for the suggestion. I posted the results below. It appears my CPU cores operate fine after a reboot, though when my system enters a sleep state, six cores lose significant power upon resuming from sleep state.

Any suggestion as to what might be causing this after coming out of a sleep state.

Thanks for any suggestion.

Re: ASRock 990FX Extreme9 sleep mode causes cpu performance loss.

Looking from here at "immediately after a reboot' could mean there are programs or actions still being performed for/during the boot process that don't necessarily need re-run while coming out of sleep.

Instead of "immediately after a reboot' what does HWiNFO64 look like 5-10mins after (re-)booting?

Looking at your Drives list, and wondering just how many you have, it could be indexing the drives. I could be caused by a lot of things after a (re-)boot.

Re: ASRock 990FX Extreme9 sleep mode causes cpu performance loss.

I figured this was the case, as usual HWiNFO64 is a great diagnostic tool. Nice work showing the difference.

The next question is, how is your CPU configured in the BIOS? Default or Auto settings? Do you have any CPU power saving options enabled, such as CoolNQuiet?

Does your CPU, when operating as shown in the after reboot picture, stay at the 3716MHz speed on all the cores all the time?

Same question for the after resume from Sleep picture, do the cores stay at those speeds all the time?

I'm not an expert on AMD CPUs, but in the after resume from Sleep picture, cores 2 through 7 are clearly running at the highest power saving state level (4), which is ~1400MHz on CPU's like yours.

We need someone like wardog to comment on this, regarding how the CPU multiplier can be set, on a per core basis for example. Why resuming from Sleep would seem to change the multiplier on most of the cores is the question. While that is a BIOS setting, Windows power options can influence core speeds.

Allow me to rephrase.

It could be the result of a lot of things after a (re-)boot.

Thanks for the response.

I have two additional HDD's attached simply used for storage. I have no backup utilites running or installed. I do have Microsoft Security Essentials running as my anti-virus app.

I posted another screenshot, this time the screenshot was taken 30 minutes after a reboot, and 30 minutes after resuming from a sleep state. The results are exactly the same as my original screenshots.

I also posted screenshots of my task manager showing the apps in use and services running, if that's any help in determining the problem.

I'm also linking to a gallery that has several screenshots of my BIOS configuration, if anyone is up to looking it over to see if something set in my BIOS is causing the problem.

CoolnQuiet is disabled.

I did experiment with the auto-OC feature, but have since turned it back to manual/auto. I posted a link above that has a gallery of screenshots of how I currently have my BIOS configured.

Thanks again for any help.

Re: ASRock 990FX Extreme9 sleep mode causes cpu performance loss.

While I don't understand all the interactions of AMD's CPU power saving features, I do see these potentially active:

AMD Application Power Management (APM), set to Auto.

Enhanced Halt State (C1E) Enabled.

Core C6 Mode Enabled.

I don't understand why any of these options would cause the behavior you see when waking from Sleep, but are worth exploring for answers.

Are you familiar with the AMD OverDrive program: AMD OverDrive

AMD Performance Tuning Guide: http://sites.amd.com/us/Documents/AM...ning_Guide.pdf

You may be able to use it to figure out what is happening, by adjusting the core multipliers in Windows, or verifying BIOS settings are working correctly.

I disabled the following in the BIOS:

AMD Application Power Management (APM), set to Auto

Enhanced Halt State (C1E) Enabled

Core C6 Mode Enabled

unfortunately this did not help.

I also installed AMD Overdrive. I was able to adjust the cores back to an optimal level, though it appears this would be something I'd have to do eveytime coming out of sleep state. Anyhow, the app did'nt play well with my system. Windows Aero theme disappears when this app is active and adjusted. Might be conflicting with my graphics driver?

Now it appears we're getting to the guts of this.

What do you consider "optimal', and maybe more importantly why is "optimal' necessitated there?

**- wardog -** · 03-27-2013, 08:47 AM

Re: ASRock 990FX Extreme9 sleep mode causes cpu performance loss.

Have you installed AXTU?

In Control Panel > System and Security > Power Options - what is shown here for choices? And also, what it is currently set to?

Take notice before and after a sleep that it might be changing.

I'm not trying to OC my board. What I consider "optimal", is simply how my system runs normally after a reboot. Not the crippled mode it goes into after resuming from sleep mode. Thats my whole problem. Why is my CPU basically staying in sleep mode when it resumes from sleep?

Yes, I've installed and uninstalled AXTU. The problem exists with and without it installed. Though I wonder if that app properly uninstalls itself. I may have to do a fresh reformat of my system and try sleep mode with only the chipset drivers installed to see if this problem exists with no apps installed.

Below is a screenshot of my power setting. I', currently using the High Performance plan.

Re: ASRock 990FX Extreme9 sleep mode causes cpu performance loss.

As a side thought .........

Damn, 50c in the BIOS? You should check the HS/Fan out. Mounting, fan RPM, and everything else about the HS/Fan. 50c informs me there's a problem.

Also, please go HERE, scroll down and fill in the "System Specs' so that we know what you have there system-wise. That will save everyone from having to continually refer to your original first post in remembering what you have there.

Please fill in as much as you can too. Sometimes it's the little things that matter most.

Profile filled.

Below I posted a screenshot of my CPU temp at idle. Is 41C the norm for this cpu at idle? Keep in mind, I have my CPU fan limited to LEVEL 4 in my BIOS, which will auto-increase the fan if the temps hit 65C.

It might have been at 50C when I took the BIOS screenshots since I was recently benchmarking the CPU. I've run 7Zips's CPU benchmark for 10 minutes straight and my CPU temp hit 64C but never went higher than that.

I didn't like the stock AMD cooler, so I replaced it with a cooler I had from my previous build. It's a Thermaltake all copper heatsink, with a 70mm fan, and Artic Silver used for the thermal compound. It cools, in my opinion, better than the stock cooler.

I could probably do a better job of improving the airflow in my case, but nothing is hindering the CPU heat wise as of now, especially for a 125W CPU.

**parsec** · 03-27-2013, 02:08 PM

Re: ASRock 990FX Extreme9 sleep mode causes cpu performance loss.

I agree that the idle CPU temps seem high, but the temps may be normal given that no CPU power saving options are used. Meaning the CPU runs at 3.5GHz constantly. Bulldozer CPUs are known to run warm, and IMO a CPU cooler with a 70mm fan is rather small for your CPU. But 65C under load is not that high, if that is what the actual temp is. The only Thermaltake CPU cooler made for AMD boards with a 70mm fan that I can find is spec'd at 65W TDP.

The AXTU Target CPU Temp setting seems to do nothing in my testing, and although your setting makes logical sense, notice that setting is the highest temp allowed. I have mine set to the lowest temp, 43C, which ought to make the fan spin faster but does not seem to do so.

Once any stress testing is complete, the CPU temp should drop very quickly. The CPU temp in the BIOS should not be affected by the stress testing.

Speaking of the BIOS, have you tried resetting the CMOS/BIOS to cure your problem? If not, definitely try that. Make careful note of any BIOS settings you use that are not default values, or save your current settings in a profile, so you can restore them after the clear.
