R9 290 non(X) overclocking results

Leave memory at stock. Focus on the core. Artifacts? Need moar core voltage. Core is your bread and butter, memory is an afterthought.
Is it weird that I can get a higher core clock after clocking the memory higher?
With the memory at 1300 I could only get to 1070 with +75mv before I started seeing artifacts... Since I clocked the memory to 1500...im at 1100 on the same voltage and after 5 runs no artifacts so far.

Well according to this thread (http://forums.overclockers.co.uk/showthread.php?t=18587078), that's how it works with these cards.

You learn something new everyday.
Artifacts are not a problem for me until i reach somewhere past 1250 and even then i think its heat that causes the artifacts rather than the cards unable to do it/lack of voltage.

In the 4th post of that thread when asked if you learnt anything, you said nothing you didn't already know (a long way of saying 'no')...
Learned anything? Thanks
Nothing i didn't know already but running on air means ill never go near 1.55v.

Well i guess every card is different. With mine i just move the sliders up and they work. Not much science to it. I don't need to run any specific ratios. If i want to clock the memory to 1400-1500, i need the core voltage at stock or higher. Core plays no part for me. I can only go off my cards as these are the only two ive owned. As ive stated i can under volt my cards and still achieve a 7.5% overclock from stock, or a 10% overclock from typical 290 stock.

Its definatly making a difference for me.. even running the memory at the stock of 1250 I get artifacts with the core at 1070...even at +75mv....But as soon as I bumped the memory right up to 1500 artifacts are gone and no issues in any bench runs. Cant complain I guess I was getting frustrated with artifacts at a core that low even when adding 75mv.

Good to hear and fair play to Ranger.

I'm not so sure.
Mine are on water and will only go up to 1250-1270 (+200mv) depending on the application before they artifact.
I think it's a case of needing even more voltage, which obviously would require more than the ref cooler.
Im getting 1150/1300 with my ref msi 290. This is Xfire with a shaphire tri x +20mv.
