Yea I think you have to force constant voltage to adjust the voltage.

Here is the EK HWBOT illustrated install pdf: http://www.ekwb.com/shop/EK-IM/EK-IM-3831109805220.pdf

They provide a copper adapter (for the 7970) and 0.5mm PVC washers to fit the waterblock to the Tahiti chip. It all looks well put together to me; that's why I am going with this block.

Has anyone tried the new Slender: The Arrival game on everything maxed out? That game is pretty badly optimized and runs @ avg 40fps on 1680x1050(my max res) resolution....My cards speeds were 1150/1500. And my GPU hit 80C @ 88% fan speed!!! The GPU usage is almost full most of the time!

I was just looking at this water block in the classifieds, and then on EK's website.. I like the look of the EK stuff... Bought a used spin bay yesterday to start expanding my closed loop.

Also checked out the TripTcc website .. awesome stuff .. Definitely going to be ordering some custom parts from that dude.

Nope, you do not. However anything under 1.256v won't matter because you're GPU will boost up to that right from the box. Therefore the correct answer would be that you need to set constant voltage to keep constant voltage...AKA, stop it from fluctuating due to PowerPlay.

Setting the voltage higher than 1.256 didn't seem to have any effect either.

hello guys,

I am considering myself to grab two of these for crossfire and I have some questions.

1. How's the card noise? I heard that it is loud card.
2. How's the temperature? I do not have very good room temperature, so I would expect to be higher.
3. I will be using CF set up for my 5760 x 1080p eyefinity. Will these CF be enough? I know it won't max every single games, but overall?
4. I been researching and I heard older mobo like mine will not able to use these cards. I heard you need to have UEFI board with 2012 bios to run these cards. Is this true? I have old i7 920D0 with Asus Rampage Extreme III 1366 Socket mobo and my latest bio support is 2011 Oct.
Does anyone have i7 920 or 1366 socket board with these cards?

for eyefinity 5760 x 1080 its worth spending the extra money and getting the HD 7950. go for sapphire hd 7950 boost. wait for this card to restock and grab it. at usd 290 (270 after rebate) its an amazing deal.

1. How's the card noise? I heard that it is loud card.

-About the equivalence of a 130cfm or larger 120mm case fan when on 100%

2. How's the temperature? I do not have very good room temperature, so I would expect to be higher.

-My room heats up quick as it's pretty small and the highest I've gotten is around 77c top card and 70c bottom card. (my case is setup for water cooling and I have the cpu dumping heat into the case which doesn't help.)

I had loud card before and that doesn't seem so bad. Thanks

7950 is better but $209 shipped was amazing price for 7870 myst recently.



Does anybody have older motherboard with 7870 Tahiti LE?

I googled and found users with problem with older mobo and here are some reviews from newegg.

Pros: Looks nice

Cons: DOA, got a refund and got the same card from another manufacturer like I should have in the first place.

Manufacturer Response:
Our 7870 Myst Edition card is a UEFI BIOS card. It is likely that the motherboard that you installed it in does not recognize the card's UEFI system and causes your computer to not POST. In order to resolve this, you will need to update your motherboard's BIOS.

If however you have already updated your motherboard's BIOS, please feel free to contact us at 626-330-4700 or by email at usa@powercolor.com for additional support.

Thanks,

PowerColor Support


Pros: None

Cons: DOA, I read the reviews and saw some other people that have an identical problem, that the PC wont POST when the PCI-E power connection is plugged in. And in my case, it is NOT the power supply. I tried it in 2 different systems and 2 separate power supplies. It seems like buying this card is a hit or miss. I submitted an RMA, and noticed now that they are out of stock. So it looks like IM going to have to wait a long time to get a replacement. And also, they want me to pay to ship it to California, when they shipped it to me from 30 miles away in NJ where I live. I hope that newegg will make this right. I will be calling their customer service ASAP

Manufacturer Response:
This card is a UEFI BIOS card and as such, some motherboards have been known to not support the video card. Due to this compatibility issue, it is likely that the card works just fine. In order to test this out, we suggest you update your motherboard's BIOS to the latest available version.

If you have any additional questions, please feel free to contact us at 626-330-4700 or by email at usa@powercolor.com.

Thank you,

I have a fairly old mobo bought in 2007...it's the ASROCK 780GXE/128M, and my Powercolor EZ runs rock solid on it! I can easily overclock to 1150/1500 with just using voltage boost. I am pretty sure I can go higher with stable higher voltage, haven't touched the momory.
IMO, ASROCK has to be making some of the best motherboards ever! I have changed so many components on this mobo, everything from CPU's, GPU's, memory and soundcards, and am in my 7th year of usage! Not to mention the countless hours of gaming and also using it as my primary PC for everything else. This mobo is just amazing!
