AMD Richland A10-6800K APU thread - Page 136

post #1351 of 1389

Here's my voltage table for Richland running on the equivalent Asus FM2 board. As you can see 1.3V is just a little low for 4600MHz and Prime95 pushed it to 45C on a cool winter's day, admittedly with a giant 140 x 32mm 2500rpm fan hanging off the Mugen heatsink. The LLC settings are the default Extreme set in AISuite II for that board but if you go to Advanced Voltage Settings page in the UP4 BIOS there are two items at the bottom of the page, VCore and NBVID Loadline Calibration that you can raise to - say - 120% to get roughly the same effect.

Here's a screenshot of my one attempt at 4.5Ghz I can see now I had the voltage too low, but it was fairly stable during this stability test, this screenshot was from after running the test for 15 minutes. I don't think I ended up getting any from my 4.6 attempt. Another thing is I should have probably used overdrive instead of Easytune haha but it's all I had at the time.




I still dont' understand a lot about the voltage stuff though. Not sure what NB means or is. I'd really like to not fry my system from ignorance haha. What geeks me about that is the difference between BIOS and overdrive, I dont' want the two to combine the "voltage upping" and just fry everything. So I get nervous about that stuff, but once I find a stable overclock setup I would rather have it set in BIOS so that it's ready to go as soon as my PC turns on (which is always, it's never off usually)

To put it in perspective the default CPU voltage for the A10-6800K when it is running at its base frequency of 4100MHz is 1.3125V. There is a lot of spare capacity in there and you can stress test it up to around 4330MHz at the base voltage before it breaks down.

 

If you look at my table you'll see that to get 4600MHz I set CPU voltage to 1.35625V (7 increments above the base voltage) and loosen the VRM controls (CPU Loadline Calibration etc) to allow Prime95 to raise CPU voltage to a maximum of 1.432V (20 increments above base voltage) during the 30 minute run.

 

If you look at the default PState settings for the A10-6800K in this AmdMsrTweaker image you'll see three Turbo PStates for 4100MHz at 1.35V, 4200MHz at 1.4V and 4300MHz at 1.4375V (you can also see the Base State at P3), so you can see that 4600MHz at 1.432V is well within the range of what Richland can do.

 

In practice this is the most overclockable of all the APU processors and many people have taken it above 5000MHz with air cooling at voltages ranging between 1.5-1.6V. I wouldn't advise running it permanently at those levels and to watch the CPU temperature carefully while you are doing so, but anything you can run below 60C isn't going to do it any harm.

 

NB stands for North Bridge and denotes the part of the APU that deals with the functions that used to be dealt with by the motherboard's North Bridge chip before APUs were developed.

 

Unless you are overclocking the iGpu (the HD8670D Radeon part of the APU) from its default 844MHz you can leave NB Voltage at its default value.

 

NB Frequency should be at least 1.25:1 in relation to Memory Frequency where the given DDR3 (Double Data Rate) Ram speed is divided by two, so 2133MHz Ram requires 1.25 * 2133 / 2 = 1333MHz minimum NB Frequency and you will usually find the BIOS setting a higher default value than that. You can raise it above the default to increase the data flow but once you get above 1800MHz you may need to raise NB Voltage by 2 or 3 increments to support it.

 

As far as overclocking in BIOS and doing so in Windows is concerned the BIOS settings are read by Windows during Boot and those are the vales that your overclocking software will start from. Certainly you can use Overdrive and EasyTune to experiment and find an overclock but when you set it up in the BIOS you need to check what the operating values end up as in case there is a transaction during Boot.

Awesome. Thanks again. I'm starting to understand some of this now. SO basically just use overdrive to find a stable OC, and then set that in the BIOS and leave it at that. Because I don't really PLAN on trying for crazy clocks, just trying to get my CPU to perform the best it can *safely*.


I'll give 4.6-4.7 a shot with some upped voltages.

My current question is, once that's set in the BIOS you said there can be weirdness after boot, so do I just need to watch my voltages to make sure Windows doesn't make em screwy when I boot up or what? Or is there a way to make sure that BIOS settings stay the way I set them even after boot?

The BIOS of some motherboards will adjust voltages and frequencies  during POST when they find certain values changed by the user.

 

So if an ASUS FM2+ board finds CPU Frequency above the base setting it may increase CPU Voltage according to the value it finds - but only if CPU Voltage was left at its default value, if you just add a single increment to CPU Voltage it won't make the adjustment.

 

If you raise the iGpu frequency some motherboards will increase NB Voltage and other boards will adjust the value of NB Frequency according to what frequency setting they find for the memory.

 

Just about all of these transactional changes are undocumented so take before and after screenshots (Shift+PrtScrn) of all these values and save them as files through your image editor (with CTRL+V) and store them in a folder somewhere so you can check to see if they came through as expected values before testing your OC.

Awesome. I'll give it a shot.

Ran Overdrive to do a pass at 4.5Ghz as a starting point since it pretty much is (counting turbo speed @4.4) and ran the stress test built in. Ended up showing around 35-36C throughout the test. I watched the core voltage on both overdrive and CPUZ and it didnt' seem to fluctuate at all while under load. All voltages (to my eyes) were okay. The only concern I had was when checking HWInfo64 I saw a 65C as a max temp in a CPU column, that scared me. Can you explain what that was/why that was?

Start:




The next two pics have hwinfo opened up where i was seeing that high temp at.

That's great! If you save the images with the .PNG filetype it will stop their resolution being squeezed. If your image editor lets you start with a large new image and paste your screenshots into that so you can use Select and Drag to build a composite of your target data, then select the result and save that as your file.

 

Since you're trying to see if values displayed in the BIOS match OS operating values it's best to use the motherboard's native OC tool to find out what they are.

 

AMD Overdrive isn't really geared to FM2/Apu and even HWiNFO64 needs a fair bit of interpretation to marry up its display with what you saw in the BIOS.

 

If you google EasyTune6 and switch to Images you will see the screenshots of it that have been used by others.

 

You're looking for how the values when you set your OC in the BIOS correspond to their equivalents in EasyTune6 compared to what they were in your OS-built OC.

 

Build the EasyTune6 screenshot for the OC you've tested in the OS then set the BIOS and build the EasyTune6 screenshot for the result.

I tried using ET6 before and didn't go so well because I didn't know all the stuff I was tuning lol I'll do that today. So far I haven't set any OC or tweaked anything in BIOS yet. I have a Dual UEFI BIOS though, so I'm hoping that means theres a way to have default on one and my OC attempts on another so that it's easy as switching BIOS profiles if something goes wokny.

I'll give an OC pass with my settings from last night in ET6 and then I'll open up the BIOS and see how badly I can screw it up there. lol
