Yeah, and I'd love to, but I've set myself a challenge to not spend anything on computer parts until 2013. 1200/1600 is more than enough for everything except BF3, and I can live with only using 2xMSAA

hey mate, it has done a few passes with 3dmark 11, but since i have recently done a clean install im currently downloading all my steam games... lol so mite be able till i find out. im hoping so because i had it at 1300/1700 at 1.25 and i was getting 10500 in 3d mark 11 and i really wanted to get that 11k mark.

sorry but i do not understand what "EC on the memory means"?

Error correction. Start at ~1600 and move up in ~25MHz jumps until you see diminished returns in Heaven. It's not worth having such a high memory overclock unless you're actually seeing benefit from it, and when error correction gets really bad you lose performance. I assume you're running the memory at 1.7v?

It's going to work - the thing is, I don't need any better. I was thinking I wanted to max out BF3 at 60fps+, so I thought "oh I'll just get a second Lightning". Then I realised that's not worth a $600 graphics card. I need a car + I want to save some money to move out, so it'll be good.

hey mate never really tried it like that. And im pretty sure ive never adjusted memory voltage only the core voltage unless they are linked together than i wouldnt know. i have rough figures on my gaming performances of my previous overclock ill test it out with that, if i dont see many increases i will start the memory from 1600 and do as you said smile.gif

ahah yeah thats fair enough, when you think about it , we dont really need to max at bf3 as long as its playable its all good tongue.gif

Alrighty - when I did my OC I set my Core voltage to 1.2 and mem voltage to 1.7. That way I didn't have to bother with slowly increasing, because I was pretty sure I could do 1200/1600 with a voltage increase. I needed an extra 25mv on the core to get it perfectly stable, but other than that I've had no issues. If you look in Afterburner it'll have a drop down slider next to the core voltage, you can adjust mem voltage from there. I run 100% fan and get high temps on the core (80-85) with my overclock, but the memory and vrms stay at a lovely 60C smile.gif

lol I just tried to run haeven and fail!!! Runs fine on 1350/1600. Fails on anything else if I increase the memory. Lol  

Bringing the core down to 1300. Find it funny how it passed 3dmark o well there goes my 11k frown.gif

Majin SSJ Eric, is 1200 on the core the best you can get? I can run 1200/1600 with no prob now that both cards are on water. Even playing BF3 for a few hours. Passed 3dmark11 at 1225/1750 with ease too.
