problem oc'ing the igp and bus on my a6-3500

post #1 of 11
Thread Starter 
i trying to oc the igp (HD 6530) on my apu, when i increase the igp frequency, stock is 444 mhz, i went all the way up to 800 mhz, it goes into window but when i test it, i get no performance increase over the stock speed?any clue what is going on? ,

i have my cpu oc'ed to 2.4ghz which is the turbo freq, because it wouldn't boost when i needed it also, when i go just 1mhz over stock on the bus speed, my resolution gets all messed up and screen doesnt display things properly no matter what i do,

lator tonight im goin to take my 580 and pop it in this comp to find out if the display problem over 101 bus speed will go away,

ive tryed every bios on the gigabyte site, they all have the same issues, is someone could shed me some light on the situation that would be awesome

It's a locked APU...not meant to be OC'd
you'd need the A6-3670K to OC. It has an unlocked multiplier.
You could keep trying but will probably fry the APU.

fry the apu from upping the bus? right on the box it says its just an athlon 2 with a built in radeon gpu, so i dont see why it would be any different from any other cpu for overclocking

You won't fry the APU from giving it an unstable overclock.  From a ridiculously high voltage, yes.  But from an unstable overclock at safe voltage... well, you'll get instability and that's about it.

 

An unlocked multiplier makes it easier to but is not required to OC an APU.

ok kool, thats what i figured. i have been overclocking for years now, and i haven't ever herd of someone cooking their cpu by overclocking with stock volts

What display port are you using? Llanos have issues with non-digital ports when overclocking using the baseclock. So DVI/HDMI out solves some screen issues.

Next is the ahci/raid modes don't overclock well at all. It varies a little but my raid limit is 104, ahci is 108. IDE works fine for oc.

Your cpu will probably need less then stock rated volts to do a decent overclock. I used intel burn test on high to see how low i could go before i started overclockling, so i wasn't adding extra volts for no reason. Same goes for the northbridge, mine is happiest at around 1.15 at high clocks, works at 1.00 at lower clocks.

Ok that makes sence about the display problem because I'm using VGA, so I will try out dvi next then, my sata controller is running in IDE, I was too lazy to change it to anything else lol I haven't did much with the comp yet, I just bOught the parts a few days ago and the first thing I wanted to do was oc it and see how well these cheap little procs can perform, prObably won't get a great oc because I'm using a cheap 80$ gigabyte board, but I'm gonna slap some cooling on the vregs and then see how it goes from there, and thank u for clearing up my display prOblem for me,

Any clue why when I increase the igp clock my performance stays the same? I went from 444 up to 800 MHz and I got 0 change in performance

Yes i know why it doesn't do anything. Its because you bought a locked (ish) apu. The cpu multi is locked upwards, so you can lower the mutti when your baseclock gets pretty high. The nb multi unlocked. The gpu multi is completely locked, but its unlocked in the bios for the chips that are able to do so, the K series. You are going to have to do it the tricky way, by going up with the baseclock.

As for the board, I can max out my baseclock (136) on a M-itx asrock board, which should be comparable to an $80 normal board, if not lower.

I skipped the display issue, as I started with the hdmi out to a tv. Ran into most of the other ones though...

well that sucks, cant even oc the gpu unless its a unlock apu, well thats boo, oh well, i have my 580 in the comp right now so i can check out how it oc's because i dont have a dvi cable right now, and i lost my hdmi cable, LOL im running a gigabyte ga-a75m-s2v,

right now im running p95 and i have it @ 3.0 ghz from the stock 2.1, and i put the voltage lower then stock, barly any vdroop, im using hw monitor and it isn't reporting my core temps properly, my core temps are 10 degrees lower then my cpu temp? is there another program i should use to monitor temp, or should i just go my the cpu temp and forget about the core temps?

Your gpu overclocks along with everything else with the baseclock.

HW monitor shows my cpu temp and cores don't match up well until temps hit 40-50c. MB fan control goes off of core temp, so if figure its accurate.

Basically your gpu speed will be baseclock x 4.43. I got better results from going up in the 130's (136 max bios setting) and getting the ram as fast as possible up there. watch the (corrected) nb frequency when you go that high, mine wouldn't play well much over 900. it would boot, but crash under heavy loading.

I saw your other thread where you asked about the ram volts/cpu volts. I don't have an answer about the ram, but as far as cpu, you shouldn't need much more then the stock 1.4v to get near the max on air. I'd try and keep it to 1.45 max, they take more, but power consumption goes way up for very little gain above 1.4v.
