A10 6800k + A88X-PRO

post #1 of 8
Thread Starter 
I recently upgraded the APU and motherboard on my PC, I wasn't going to get another APU, but reading what the mobo did swayed me, that and the price.

Specs:

CPU: AMD A10 6800k Richland

MOBO: ASUS A88X-PRO motherboard

RAM: G.SKILL ARES 16GB (2 x 8GB) DDR3 1866

CPU COOLER:
Antec Kuhler H20 620

PSU: COOLMAX ZU-700B 700W SLI Ready CrossFire Ready 80 PLUS BRONZE Certified

HDD: Hitachi 1TB

and I have a few questions.


I used the Dual Intelligent Processors 4 program that came with the mobo disc, it easily OCed to 4.8GHz, I've been playing a lot of Star Wars the Old Republic on highest settings around 60 FPS without any issues, but I'm a little OCD about the CPU temp. Idle is around 26°, it steadily rises to around 45° when playing, and after about 5+ hours of steady gameplay rises to around 47-52°.

Is this an ok temp?

Is it ok leave it OCed, or just OC when I go to play games?


I guess I really am OCD about it, I've rearranged the fans in my case, including the H20 620 radiator multiple times to see if there's any difference.

As of right now I have 2 fans on the radiator as push and pull exhaust out of the back of the case, one exhaust up top (which I just added and doesn't seem to affect the temp at all.), and 1 intake up front.

I even tried the H20 620 as an intake like Antec recommends, with my front fan as exhaust, but it only dropped the CPU temp by 5° and raised the mobo temp by 10°, so I threw that idea away.

What do I change to correctly lower the OC?

It looks like all I have to do is lower the "APU frequency" on Dual Intelligent Processors 4 and it takes care of everything else.

Is it safe to assume my DRAM is taken care of in Dual Intelligent Processors 4?

My RAM is 1866, but has always been at 1333, D.Skill says adjust the timing manually, but I was always kinda scared to mess with them. Do you think the program takes care of setting them around 1866? The DRAM section shows that they are capable of 1866, so I'm guessing yes.


4.8GHz

APU frequency: 105
Ratio: 46
CPU: Voltage 1.5
DRAM voltage: 1.5
APU1.2 voltage: 1.2
VDDNB voltage: 1.8175
SB1.1 voltage: 1.1

Thanks.

Chips are designed to run at high temperatures. Its FINE, you're worrying about it too much. 80-90 should be the point of worry.

^exactly, I'm running the same motherboard and processor as you and I keep it at around 5.2ghz all day erry day with no problems. With 100% load it hits about 55C. Where you want to start watching out is the 70c mark.

Go to the bios and get that ram up to speed, you'll see gains there esp with igp.

There should also be a 'DOCP' setting that reads XMP profiles off of the RAM and sets the timings accordingly, didn't have issues on my F2A85-V Pro in doing that and should be available on yours as well.

Feel free to manually adjust timings and similar (although careful if using voltage), the worst that happens is instability or non-boot, once you clear CMOS or hit memOK you're back to the races.

ah ok, thank you all.

Here is my 2 cents! With the APU cores you do not want them to run hotter then 65 for long periods of time. Remember, these cores have an integrated GPU! Thermal shutdown on the APU is 70, compared to other chips this chip is more finicky when it comes to heat!

As for your memory, if you can OC and get it to run faster DO IT! Also ALWAYS use dual channel memory! The iGPU is dependent on the system memory for operations, so the faster it is the more bandwidth you will have. The same goes for using dual channel!

I am, however, curious to know why you are running at a 105 FSB and 1.8175 VDDNB? By OCing your FSB it will increase the GPU clock and mem clock. As for your VDDNB that voltage regulates your iGPUs OC ability, though not knowing about your OC on the iGPU I can't say definitely, but that is very high! Lowering that will help with your heat concern.

Well seeing you used the on-board OC, I can believe that it would have raised your FSB. I would claim that you would be better off lowering it to 100 and raising the multiplier to 48 if your wanting 4.8GHz.

If you have any other questions, feel free to ask me!

I think you probably have a lot more voltage on that chip than necessary for those clocks. 1.50V may be good for 5.1-5.3ghz overclock territory on these in my experience. Given the cooler you have there, you can probably do 5ghz or better. For 4.8ghz I would suggest ~1.40V as a starting point for testing. Assuming your chips is anything like mine, 5.0ghz@1.45V will work, and should not have any more dissipation than your current 4.8ghz@1.50V setting.

On my Richland machine, 4.8ghz @1.37V is stable, might even run lower voltage for this speed but I haven't had the chance to test long enough to confirm (saw short term stability at 1.36V under a load). Keep in mind that's the actual voltage under a load (not the voltage setting, which is derived from a VID offset). Using medium LLC settings for this setup at the moment.

I'm not familiar with the control available with software overclocking like that so can't really assist you on the "how." I will say, that learning to do BIOS overclocking may be preferential as it will likely offer you more precise control over things, which should lead to a "better" overclock. (either better due to having less excess voltage/heat, or better because it has low power states intact, or better because it is faster, or any combination of things)
