You should use Beta 9 while you're at it.

I changed back to lgeacy mode and it shows power limit now, but not shader (?)

Pretty satisfied with my cf 7870's. Just used the CCC beta drivers and power play at 20%. No afterburner, cards at BIOS .28.

Bought them from newegg, sold the game coupons for $50 each so all in only paid $320 for the pair.

Well it happened again .. first SuperBiiz.com .. now TigerDirect.com .. Both listed the cards in stock.. I even called TD to confirm .. within 12 hours of order I got an email saying the cards are backordered.

To add insult to injury, they STILL list it in stock on the site and it will still allow you to order one..

If you "NEED" to add something to the myst to play the games you want to play,, THEN you really should've just bought a more powerful card...

that is your opinion, infact i didnt buy this card for back/buck nor play games. i bought it so it can handle 3 clients when passing through VT-d.

i do have a more powerful card that i'd rather use namely a GTX670 none the less the 7870XT is a self immolating oven that does require cooling modification to run at a decent temperature without sounding like a jet and heating my entire case(including its metal bits) to 70c

seriously....... none the less the card can run the games but i dont wish for it to be an oven is that too much of an ask

Even my Sapphire Dual Fan cooler runs pretty loud and toasty under heavy gaming loads. It's not like we're dedicating $80 JUST for the card, we can always use the mod on another card, the brackets are universal. Not only that, but no air cooler can match the thermals/acoustics of a 620 or an H50.

Do the clocks stick on these cards when you over clock or are they all over the place?

If I look at my GPU-Z using crossfire, I see VRM1/2 senor from only one of my card.
So strange that choppy GPU usage still gives you good benchmark scores. It's very irritating frown.gif

I just ran Dirt3 benchmark on my crossfired Mysts, max settings, 8xMSAA, 1920x1080 and here's what I got:

Avr. FPS 186.87
Avr. min FPS 145.76
GPU1 max 70C
VRM1 max 74C
GPU2 max 60C
VRM2 max 74C
Memory Usage max 1473Mhz
Volts max 1.24
ULPS disabled without powerplay support

2500k @ 4.2Ghz, Asus Sabertooth Z77
2 X PowerColor Radeon HD 7870 LE (Tahiti) @ 1212/1500 in crossfire
2x4Gb Corsair Dominator GT @ 2133mhz
Crucial C300 128GB SSD, Antec HCP-750 PSU

I don't seem to have the overheating problems others are experiencing and I wonder why?

I don't think we're complaining of overheating just more of a noise thing. I know I have mine set to hit 100% fan speed at 70c cause heat will kill cards overtime.
Those temps look like mine until I overclock then it'll hit 76c or so.

I'd say it's more of a greed thing than a heat thing if we can do something that'll allow us to overclock these cards more, then why not do it? Plus modding is fun, and the antec 620 mod is reversible unless you plan on cutting the shroud up (it's also universal with Dwoods brackets).

That second gpu looks crazy, did you enabled Overdrive in the CCC panel? If so the two programs will conflict and the only way to fix it is to reinstall CCC again.
Afterburner Beta 8 and 9 both don't have the in game on screen display support, which I can't stand.

On another note, I wonder what would happen once under water if you were to vmod and cap mod these cards lol.
I know someone had taken a regular 7870 and made it run 7970 speeds so I'm sure these would exceed that.

IMO trying to do much of anything for less than a 10% performance gain is a waste of time and money. Also seems like a 7950 would perform better after OC than a 7870 with a water block.

That said, if someone just wanted better acoustics, would it really make more sense to spend $290 for a MYST+water block or to get a GTX 660 Ti which would be, cheaper, and not require modding. Also, SLI is currently superior to CF, if they ever wanted to head that direction.
