it got more worst .. this 2nd test i run

i think bug 

G-sync and freesync tested via oscilloscope. It is important how both technology handle VRR below the panel refresh rate.

It looks like G-sync deal with low fps smarter than freesync.  In a nutshell, freesync just stop doing it works at below panel refresh rate, leave you with the classic stuttering and tearing.  Meanwhile, g-sync doing frames interpolation (double or tripple the frames), and match it exactly with the refresh rate.  Genius.

If you already using nvidia, changing to ATI is even costlier.

None.

There was rattling, but I found that it was my wifi card lol. Gave me headaches trying to "fix" the GPU 

Why is there two accounts selling in lowyat garage sell, but both are the same under idealtech? yongkeen and zhenwei.

Is it safe to buy from them? I want to buy some thermal pastes from them.
Not coil whine. I had coil whine before but it isn't loud. Now I using better PSU coil whine is very rare.

soo any idea which is which ??
I try furmark for 1 hour with max settings without prob ! is this enuf to proof this card is stable ?

That is only applicable to R9 290X and NOT R9 290. You can read the review here. Like terradrive said the switch merely for either legacy BIOS or UEFI BIOS.

thx everyone !!
been playing farcry 4 and advance warfare for few hours !
I oc the card 1150 MHz core and 1500mhz memory with temp around 74 c with auto fan profile at 40%
1 thing I notice my gpu core wont run at 1150mhz ! its running 1100mhz only
my pc running at naked !
waiting for my nzxt s340 case  !

i think my score will be low ! bcoz im running g3258 in 4.5ghz only !
still deciding 4690k or  4790k !

Didn't happen to me.

hi guys, whats the max OC settings for Sapphire 7970 and the safest temp for it ? Thanks

haha thats the problem, i lazy to tune it myself, i mean is there anyone that already oc their 7970 to the optimum and i just wanna take their settings thats all XD

overclocking to its limits without tweaking voltage is easy

1. get a good OC software
2. check websites on what its average best overclocked speed
3. tweak your own card's speed as you like. you can choose the slow and steady route or the lets see what can it do route
4. slow and steady is where you increase like 5-10MHz and test each time on games/benchies
5. what it can do route is, just throw in something like 200MHz and watch if it succeed the benchies. if it fails, drop 20-50MHz and repeat

do it until you reach to the point the game runs fine with no artifacts and issues. thats your overclock!

as for temps, its super subjective. one person can withstand GPUs at 80C, while another die die also need it to be at <60C

in short, if you feel comfortable at the temps, then its fine. but if you want to follow the rule of overclocking, lower temps = better

I don't think backplate will help with the heat that much. People install backplate for the look and to make the card more sturdy.
