no dual bios, low locked voltage?

XFX strikes again.

Wow, really...never again XFX

They did not even reply me back to my further questions on their support site.

I will not try the bios modding, too risky for me, anyway already raising core gpu clock to 1000 gives me enough more FPS to play smoothly.

Too bad this card is so limited, bad choice

Many thanks for the help anyway! To all of you!!!

XFX cards are what they are...they have their place in the market as a budget alternative. But if the word "overclock" is part of your vocabulary, then "XFX" should be avoided. Back in the hay day of the mining craze, they had the lowest hashrate of any card on the market. Once you find a good overclock, you can set afterburner to apply clocks at startup, and then just game on it. Everyone gets a lemon every now and then.

Yes, i got lemon smile.gif when i bought it i was not interested in OC, did not think it was worth it. Now i realize that for gaming CPU overclocking is not worth it (ok, kill me now) but VGA is.

i could still backup the bios and try to mod it with your previous guides, couldn't I ?

Without dual BIOS, if your flash goes wrong, it can be very hard to recover. Yes, it is possible, but I am not sure what you expect to gain from it.

Without being able to bump the voltage, you aren't going to get a high OC. My Sapphire 7950's were voltage locked as well, but I could get a semi decent overclock out of one them using Trixx my modding the power limit to go higher than +20. I was able to force the cards to go higher up to +40, and I could get a hefty 1100/1375 overclock out of them. But they would begin to artifact in certain scenarios.

I would expect to get at least 1100 Mhz on the core clock. Now at 1035 i could play at dragon's dogma with all graphical mods and ENB at 60FPS 99% of the time.
But sometimes it would crash. At 1000 mhz is stable but sometimes they drop to 50 or even below now, end game adds some particle effects in all the world...

So with 1100 mhz at least it would be as smooth as silk.

I don't know, maybe i will wait until i decide to buy a new one. If i cannot sell this for more than 100 euro, i could take the risk and have some fun smile.gif but first i need to study a lot from your guides

With +20 you mean the 'power limiti' in MSI ? the one that refers to TDP ?

I tried to raise that but no improvements. You are right, i should manage to overvolt if i want more juice

Correct. The Power Limit allows the card to request more voltage if it's needed. +20 didn't give me much headroom either. But some mods to allow +40 allowed me to get the overclock I wanted out of the cards.

*edit* And I just sold both my 7950's on eBay. I got $259 for both of them ($59 more then a I expected). I secured my R9 390 that way. The 7950's are going for $125 all day long.

FTFY

Power slider wont help unless you are bumping into your TDP and getting throttled.
