And what is a memory to core ratio?
Thanks!


1st are you on air or water? If you are on air, that's definitely going to limit you as you will encounter throttling at some point. You need to keep your memory at default, find max stable core clock, then work on your memory. Bumping everything at once isn't going to help. There is also a neat little tool that locks voltage to core clock. Use that initially to get an idea of what volts you need at what clock. You'll probably need additional volts at some point, but it's a good place to start. An unstable memory oc will limit you so find core max 1st. WATCH YOUR TEMPS. Stay under 75*
You have to remember every chip is different and just because someones matrix can do 1375/1875 doesn't mean yours will. It's what they call the silicon lottery. Sometimes you get a good chip, sometimes you don't.

bump llc to 75% and power target to 120%

What sort of temps are you seeing?

Can someone tell me what is happening or how to make it not happen? The Asus card is my bottom card and its running a t99%while the top card is down clocking as normal.

Disable ulps. Or try newer drivers.

Have the latest drivers. Didn't start to do this till last night. Friday and most of Saturday it was great, low temps on both cards, but now .........not so......

Ok, thanks for the info, will try it tonight.
Also Stay Puff, whilst overclocking I had fans at 100%, and the max temps were 72 degrees.

Edit:

Also, I am running it on air, and what voltage would you suggest try to stay under?

Temps will dictate your voltage. Unfortunately I have another card I'm in the middle of testing, but after I get my Matrix back in I'll give you hand. My current Matrix is a bit more efficient than what you have. (1.219v stock) But my last one was spot on to what you have stock. It shouldn't really take more than .035-.040(1.292-1.297) to get 1200mhz. That's tops. I don't have a block on this Matrix yet and I'll be testing it to see if I want to put a block on it. The last 2 I've had, were solid oc'ers.

Theoretically i can buy any 280x ... but i just do not know what to chose ... what factors are the most important ?...
With all options on the table... which would be the best choice... and why ? ...

Not bothered with that power test, furmark is null and void as far as I am concerned, there really is no need to put a GPU through so much stress as it'll never get close to that power draw while gaming unless your able to clock the living hell out of it.
As far as which card to buy, I would say the Toxic depending on what your paying for it, I really can't fault this Gigabyte card either.
1100 core out the box is pretty respectable. Its gonna come down to what you really want.

I am not a fan of the Toxic color scheme, but there is no denying its a cracking gpu.

So after close to 2 years of Asus making a 1100mhz monster and MSI's Lightning, Gigabyte finally gets off its laurels and comes out with " The Toxic". Where are the records? Oh, that's right, Asus and MSI have them. Lol!
