Disabling C-states will help with your OC also.
Enable PLL Overvlotage
Increase your Current Core Limit. I have mine @ 300
Have you tried your RAM at XMP settings without adjusting timings?

Both GPUs are the same but they have different bios version and I've try to run 1 card at a time and the temp. is just the same for both cards, so I think I don't have good airflow at the moment. Hopefully it gets better when my fans be here on next week
I used to have a HAF X and the airflow is great, so I tihink I just need some fans to blow air on the GPUs.
I didnt get any beep either.
Thanks for replies guys

Added 2x120mm fans on the side panel didn't help much...
This is the first time I work on such a big case and I learned that it is NOT easy to get the air to circulate properly in such big case! not sure if it applies to only Cosmo II or any BIG cases.
The case does not trap any warm air in the middle after I:
1) moved the Antec 920 radiator from the front top fan spot to the back (where the stock 140mm fan is) of the case
2) installed the 3 top 120mm fans in intake mode - the rear two helps to cool the VRM heat sink & DIMMS. The front one helps to push more air from top to bottom of the case. BTW, I connected the two rear top PWM fans to the Antec Khuler connection/controlled by the Antec Khuler software. So that the VRM & DIMMS will get better air circulation when the CPU temp goes up. I wish I could afford changing all 120 mm fans to Noctua fans... The way the Noctua fans sound is just so nice compared to the stock Antec Khuler fans, especially in higher 2400 rpm.
3) Added a 120mm fan at the bottom part of the case, which you had already done so. I found this fan + the front top fan (both are Cosair AP-12 performance) helped to push more air towards the SB area. Making the 2x120mm side panel fans more useful. I connected this bottom fan to the top fan controller as well. So that the Top Fan controller can control how much air is being pushed down from the top front, to the bottom and rear end of the case. SB temp dropped by 4 degrees when I set Top fan to run in high speed. The XFan stopped running at 6000rpm when I set it to 53c. It just runs at 3000rpm or even not running at all after I spent so much time playing with the fans! Gut feeling tells me that doing this may help you....
Now I don't feel any warm air being trapped in the case anymore. All I feel is a lot of cool air circulating inside the case. The easiest way to tell is to, with side panels closed (I found air does not circulate the same once you open the side panels, or even the 5.25 bay covers), open up the 5.25" bay to get a sense of how air circulates inside the case. I feel so much cool air coming out when I open up the front 5.25 bay covers.
Hope this helps,
jack

Good info for me here.
I'm Win7 64bit too, so the 16Gb would have puzzled me. .
Is the "red" side the way to go if considering 4 x GPUs, to make best use of the 2 PLX PEX 8747 chips properly.
Is it overkill having two PLX chips for current graphics scenarios (multi monitors and minimum framerates)?
