Overclocking A10 6800k (CPU only) temps and voltage

CptBarbossa · Aug 16, 2014

Ok, so I am overclocking my a10, and I seem to have hit a wall at 4.7ghz. Anything over that fails prime95 test. I am stable at 1.475 volts and thermal margins are good and temps under 60c. I am cooling with an H80I and running on an asrock FM2A75m pro-4+ motherboard.

I have tried 4.8 ghz at up to 1.5 volts, but even that isn't stable. I have done the usual such as turn off turbo core, set manual to core clock and voltage, etc. I guess my questions are...

Is my bottleneck my chip? my motherboard?

what is the highest voltage for everyday use, and what is acceptable for just benchmarks?

Is there anything related to the northbridge I can do to help stabilize the o/c?

Max acceptable temp for day to day use?

Thanks for the help

Ok I am really leaning towards my motherboard being the problem. The more I read the more I am convinced that an a88x motherboard is necessary to reach higher overclocks with this cpu. Anyone have any other thoughts?

Your chip isn't the bottleneck.
1.3V
Not really, read this: http://www.tomshardware.com/forum/id-2028635/overclocking-a10-6800k.html
Below 65C.

4.7Ghz is pretty good speed. Why do you want to OC further? There'd be minimal increase in performance, if not none.

CptBarbossa · Aug 17, 2014

So do you think it could be my motherboard?

CptBarbossa · Aug 17, 2014

I just enjoy getting the max out of my cpu. I enjoy playing around with overclocking. I dont really have a real world reason to do it other than that I enjoy it more than playing games.

MeteorsRaining · Aug 17, 2014

I understand your urge to OC.
You should be able to hit 5ghz if you're not also trying to overclock the graphics at the same time.

CptBarbossa · Aug 17, 2014

Yeah see thats where I am confused, I tried increasing the bus speed 105 but it crashed right away. If I choose to try and up the bus speed the I need to up the bus voltage? and if so how much? I am not afraid to use the bus to help along and overclock (tho I know it isn't the preffered method for unlocked chips). Just curious

Any say on max voltage to try before giving up on the 5ghz?

MeteorsRaining · Aug 17, 2014

If you OC your CPU and embedded GPU both, it'll produce more heat and the CPU won't be able to get to its potential.
You'd probably need to up the Voltage if multiplier isn't helping. Try by increasing 0.01V.
1.47V or 1.48V before giving up. NEVER go beyond 1.5V.

CptBarbossa · Aug 17, 2014

I have a dedicated gpu, so the igpu is turned off automatically (i assume). I am going to try to get to 4.8ghz. I ran a longer stress test last night and found that it eventually failed at 1.475v so I am already up to 1.48125v. I have been running the stress test for a while now and it seems to be holding at 4.7 rather well.

Just rather disappointed I guess. I couldnt get my amd fx 4130 past 4.7 either despite plenty of thermal head room left, and I was really pushing the voltage on that one as well. I am going to look into it and see if there is something I am doing wrong in my bios cause me to need such high voltages on my overclock.

Thanks for the help. I will report back with my findings later.

MeteorsRaining · Aug 17, 2014

I'll be waiting and willing to help, all the best!

CptBarbossa · Aug 18, 2014

Went through the whole bios and couldn't find anything that would be holding me back. I also tried overclocking slightly by bumping the frequency and underclocking the ram and nb, but to no avail. I really think I am stuck at 4.7ghz, which sucks because I have read about people getting that at stock voltage, not at 1.49v.

Now I am seriously leaning towards the motherboard being the problem. Going to look into a a88x motherboard. Any other ideas would rock. thanks.

MeteorsRaining · Aug 18, 2014

The only thing I can suggest is to stop trying, some CPUs are 'VCore tantrum' type. Changing MoBo will most probably not help. I've seen some FX touching 5GHz and some calling it done at 4.6GHz, so maybe your CPU just doesn't want to go further.

CptBarbossa · Aug 18, 2014

Yeah thats seams to be the case. I always seam to get the bad apple chips, but hey, I guess someone has to. Thanks for the help!

MeteorsRaining · Aug 18, 2014

All the best!
PS: Don't forget to select a BA if you think I was of any help

CptBarbossa · Aug 18, 2014

Ok I know im probably spitballing here, but I am going to try uninstalling and reinstalling prime95, and I am going to try a intels burn test and amd stress test. I don't know why but I need some more confirmation before giving in on this thing.

MeteorsRaining · Aug 18, 2014

Sure, test it with your heart, its all yours!

CptBarbossa · Aug 18, 2014

Ok I am toying around with the loadline calibration. From what I have read it basically throttles back the voltage on your cpu. I have several setting, default, vcore 1/2, vcore + nb 1/2, and vocre 1/2 nb 1/2. I really dont know how to interpret these. Is there are way to disable llc altogether to keep my voltages constant? If not I will toy around with it to see if it makes a difference. I have set my LLC to vcore1/2. I really don't think I need to mess with the nb vcore since I am just using core multiplier for the overclock. Thanks.

MeteorsRaining · Aug 19, 2014

I hope you can choose LLC in percentage from the BIOS, 0% means disable and Auto is a fairly high percentage. Disable it, maybe it can make a difference. Using multiplier alone is the best option, until you OC competatively.

CptBarbossa · Aug 19, 2014

I put it to vcore 1/2. I am pretty sure I cannot disable it (didn't see anything to indicate that I could). I was able to get 4.7 ghz stable at 1.425v, and preliminary tests show 4.8 is stable at 1.49, but thermal margins are extremely close according to amd overdrive (within 2 degrees at times). The temperature readings seam to be pretty eratic though. The temp monitor from asrock looks much better sitting at 55-58c. I am going to try and drop the voltage just slightly and see if I can get 4.8 stable at a more reasonable thermal margin.

MeteorsRaining · Aug 19, 2014

Try. I can certainly say a BSOD will follow. But has that ever stopped an OCer?

CptBarbossa · Aug 19, 2014

I decided to take a different route. I got decided to up the base frequency to 102 with a clock of 4.7, which put me at 4.829ghz. I have the voltage at 1.4625 and it seams stable with great thermal margins. I underclocked the fsb and the ram for now just to eliminate those as potential fail point. I am going to up the base frequency (not going to go past 105), but this seams to be a MUCH more stable way to overclock.

CptBarbossa · Aug 19, 2014

Ok, so if I keep finishing my overclock with the base frequency, I have to hit 107 to make 5.029 ghz. Is that going to cause any major problems? just a 7% increase on the base frequency? I underclocked the nb and ram to make sure those stay stable, but I know that it overclocks other parts of the system as well. what do I need to keep an eye out for?

MeteorsRaining · Aug 19, 2014

Way to go mate! Good OCer you are

Everything looks fine to me, enjoy!

CptBarbossa · Aug 19, 2014

Maxed out at 4.829. Not bad. Not what I wanted but not bad. Thanks for the help.
