Hi all,

I have an x-edition VTX 7970 that I have currently overclocked to 1180/1600 using MSI afterburner. Firstly, is this any good for this card?

Secondly, I haven't been able to get it any higher than that even though the temps don't go over 60C. Any thoughts on if I should try getting higher using some other software that might work better?

Thanks in advance,
Jim I
 
Leave it, its a good over clock and good temps too. You certainly got your moneys worth with that level of performance, so I wouldn't push it (well perhaps for a few benches :p)
 
I havent changed the voltage at all, just upped the speeds on afterburner. I'll look at the volts when i am not on my phone. What is the most reliable monitor of gpu voltage?

Thanks
 
My edition x won't OC at all without increasing the volts, hope you're stable, sounds like a great card.

Use msi afterburner for volt increase OC.
 
Thanks, i'll get into it and check out voltages etc when i am home.

Very happy with it so far as its my first outing with overclocking.

LOL, I would be throwing all my toys out the pram if I were you! You can more then that from most reference cards.

Indeed. We are all suckers for clever marketing in one way or another though. And the MSI Lightning is clever marketing when in truth I could buy a cheap as chips reference 7970 and push it higher if I got a good clocker.
 
Was a little dissapointed, but got it at promo price £380 on ocuk so was happy with that. Hopefully will be putting it under water and it should do better then......fingers crossed
 
Had a little more of a play this evening and unlocked the voltage on MSI afterburner. Just upped the voltage slightly to 1149mV and achieved a stable 1200/1600.

Temps are up to 62 degrees and everything else seems good. Don't want to push it until I have sorted the cabling out for better airflow (awaiting some cable extensions) but guessing it will go further than that.
 
I'm well chuffed with it so far, particularly as I got it with the 10% off Facebook deal a little while ago made it fantastic value.
 
Can't seem to get mine stable even in furmark, tried 1300v 1200 1600 lol, does not want to bloody work!

The ram is rated at 1500 so I am tempted to just leave it there, since this VTX has no vram cooling.

Shall keep working, but tips appreciated.

Also according to most threads 1175 is the stock voltage for 7970s ( I hope).
 
i'm getting mine today thanks to some seriously kind help from ocuk staff :).

stock voltage depends on your asic, and it's somewhere between 1.05 and 1.21.

also realised the other day that this card isn't reference pcb, though it is reference design. it has an extra vrm (which is a good thing) and a few small differences like 2 different chips and different caps. also the ram on this pcb is rated at 1.6v instead of the 1.5v on the stock pcb (same specs otherwise). while these chips are hotter running, a nice benefit is that higher voltage ram is often easier to overclock. so with some ram heatsinks the vtx3d might well get the most stable high ram overclocks on average (and reviews seem to see the vtx3d getting outstanding stock voltage memory overclocks, especially so without dedicated heatsinks). so you're buying less expensive ram that goes further! a good candidate for an aftermarket cooler probably - may well get one down the line when i inevitably overclock this thing.

asic is the quality of the chipset,the higher the better oc ability,but its not 100% guarantee

1068v is pretty low default voltage so it might oc well

My VTX X-edition has an identical PCB to a stock reference 7970 ?

so i got the card, and i was wrong about different chips. it seems to be different soldering method on the back of one chip, and a different brand of vrm on one of the vrms, different brand capacitors, and one extra ram vrm. the ram chips are also a different spec with 0.1 extra v - it looks identical and potentially gives slightly better overclocks with cheaper parts (ram at least) ironically

edit: the easy way to tell is it doesn't have the amd logo on the card
