MSI hawk overclocking?

[(G{in}[AK)TION]]

has anyone been able to get highly successull clocks on their AMD Radeon MSI hawk cards? because even when i am at 1170mhz on core and 1200 or 1300 on memory, i crash. and yes, i am overclocking them in symmetry

 

i also noticed that one of the cards have odd temps like sometimes one is hotter than the other and then vice versa.

 

im thinking of either replacing my PSU (even though its reading good voltages on the meter) or the two cards and the motherboard (motherboard had to be replaced three times because it was having issues...no matter how well i took good care of it).

 

SPECS

Intel Core i5 3570K Processor

Asrock Extreme4 Z77 motherboard

X2 AMD Radeon 7870 (crossfire) Graphics cards

Corsair CX750 Power Supply

8GB G.skill Ares DDR3 (1600mhz) Ram

NZXT Source 210 Case

 

if you dont understand, im sorry. but im posting this in a rush since i have to go to some stuff around the house.

Some suggest only OCing one thing at a time. For instance, overclocking your GPU, making sure it's stable, and then bumping up the VRAM and making sure that's stable.

ill try to just overclock by 5mhz on the core every time im done playing a game until i see it crash. and then try raising the mem and see if that stops it.

Post back your results. I may not see the post right away - but perhaps someone else will be here to assist you if I can't.

The top card will always run hotter as it has a harder time getting fresh cool air.

also one card may OC better than the other so if u OC the same only 1 maybe stable. A OC is not certain so just OC as much as you can and leave it at that.

i was going to start this tommaro but as i was watching some videos on you tube while bitcoin mining with stock GPU settings, the tab crashed...never did that before. first time right there actually. 

 

i mean its done this with games in teh past. they either randomly crash or show some black lines and white lines while gaming but this is a first for me...

i guess picking hawk cards are like lottery tickets for everyone. lucky one has the one that can oc really well

well when i was having problems, it was the other way. along with black lines and white lines appearing while playing sleeping dogs.
