Hi guys I'm after a nudge in right direction for as title states a10 overclock help.

I'm not a noob been around the block with many a amd am3+ cpu bulldozer piledriver ect, but having a bit of a head scratcher with these apu.

Specs
A10 7850k on closed loop cooler
Asus a88x plus matx board
Hyper x ram 1866mhz
750w gold psu
Ample case cooling idle 28c
R9 270x gpu

So I'm @ 4.3 ghz 1.46 volts which is only voltage I could get stable, I've seen endless posts about higher clocks on a lot lower voltage wondering if anyone could shed some light on where I'm going wrong??

I have all the usual bios settings in place eg. Llc all power saving off ect
But these volts seem way to high and no matter how much I pump in I cant go over 4.3ghz. How people reach 4.7ghz is beyond me lol

User error or bad cpu maybe any help be great
 
This was my fear thought it was stable @ 4.3ghzbut woke not long ago to find system has froze on me grrrr.

I'm stumped there are a few settings in not used to with these apu rigs anybody who has overclocked these any tips would be great help

Not after new rig as its just cheap build to game on as I lodge away a lot for work so I can just pop it in car and away.

Being that I had discrete gpu already may buy 860k if I cant sort this chip
 
Since you have a discrete gpu, gaff you disabled the igpu? What have you done with Northbridge voltage etc?

Are you using too high llc? What are your vrm temps like, Dora that have airflow across them? They people with higher overclocks, are they using the same board?

What power states are you using, have you disabled cool and quiet etc?

1.To my knowledge its auto disabled when you connect dgpu is this not true?
2.nb voltage is bk on auto
3.i have tried with different llc combo to no success
4.vrm has a fan blowing on it so there fine
5. I have seen people using this board yes at different speeds all higher than mine
6. All power saving is disabled yes

I'm new with apu clocking,I have a 8350 clocked to 4.8ghz on water I used my knowledge with them but these are a tad different I just wanna determine if its me or the chip?

Why do people still overclock like it's 2004? Cool and Quiet doesn't affect overclocking. What software you using to test stability farmerboy?
Gf28shp isn't great for clocks (4.3-4.4 is generally the brick wall for these chips, so I imagine you have reached the thermal threshold of your apu. What are your core and cpu temps?

If high temps have you tried taking off the ihs to see if the thermal compound is well applied.

Hey davedree I use Intel burn test and realbench as I don't think prime95 is good fir these chips

My temps are good 28c idle benching high 40's low 50's I put new arctic silver 5 on when I built rig few days ago have checked and still good temps are perfect fir my h55 imo

How are people getting 4.7ghz if 4.3 is the threshold? Not saying your wrong but loads of people claim to have reached those clocks
 
I only had a 7750 gpu to compare it to do good thing you checked.

I don't believe he has reached a thermal wall as on water and lower voltage. The reason for disabling these cool and quiet etc is because these apus throttle like a mother especially if the igpu is used unless you need around with the power settings and turbo modes etc. Note I did suggest he might have his llc too high as suggested in some reviews and on extreme systems forum by some people.

When your system freezes, are there any loss in event viewer to indicate an issue?

Btw, I run my apu at 44/45 with the igpu overclocked with one fan on the hsf (evo 212) with q case fan, and the temp outside yesterday was 100 degrees f (about 36c)... it it's nothing to do with thermal unless there is bad case airflow.

How are you setting the memory speed, spd/xmp/amd profile?

Basic question, are you on a good version of the bios for motherboard? Have you checked asus forum for this motherboard?

I have good case airflow thermal definitely not issue max while stress testing was 56c on cpu

I'm stable @4.2 now gaming stable at least I will post pics of all my bios settings and see if that helps shed some light

When it crashes it blue screens as soon as I put cpu under any load

Llc is at medium and voltage stays where I set it not jumping around at all which I was when I had llc set to extreme

Will post pics soon

Cool and quiet c1e c6 are not reasons for throttling. Hpc and apm mode are the reasons for throttling, and weak Motherboards due to cheap power delivery,aswell as the throttling due to badly written bios's (3ghz p-state when igpu when loaded up (As I know you are aware fella).

4.7ghz is not easily achieved the average is 4.3-4.4 and at this speed this is where they usually hit a brick wall and usually require big voltage, or extra voltage just doesn't help them scale any further. Most of those people are probably using expensive motherboards with an 8 pin atx power connector and 6+2 phase and lucky silicon which is responding to the voltage, or they aren't actually stable at those speeds.

It seems that his cpu suffers from bad leakage and isn't scaling in frequency to voltage, or his motherboard isn't providing clean regulated power (4+2 with a 4 pin atx connector should just about cope with 125w). Just because he isn't reaching peak temperatures doesn't mean the silicon isn't reaching a thermal/frequency threshold just before the point of crashing, also the ihs are glued on with compound which isn't great for transfer of heat.

I agree maybe the voltage needs to be reduced lower rather than trying to push it hard with voltage.
 
Here are all bios pics guys maybe you be so kind to have a look and see whats up if anything, like i say im new to apu but not overclocking as such just need nuudge right way

Dave, I do get that the throttling is down to APM etc :) I just like to rule out any interference, especially as I run mine full speed all the time when in usage (once I start doing anything strenuous on it like gaming)

Farmerboy, try using 'CPU Power Phase Control' on optimized rather than extreme. Extreme can get things a little toasty. See if that helps.

I'll try and screen shot mine...you'll note I run MUCH higher voltage on mine.

EDIT: Here you go... here are some screen shots from my BIOS: I'm not saying for a second that my are what you need, it's just what I have done so far, and a lot of my voltages are auto set.

I would check what people consider 'safe' voltage btw... I think mine might be higher than what people consider safe.
