I guess we can close this thread.

Answered my question, just got another WC'd 5970 in my Rig.

2x 5970's WC'd.
1x 5970 on Air.
1x 5870 on Air.

All happy hashing away at 2.9 GHash/s. Could overclock more to get to 3 GHash/s, but I like all my temps below 90, besides the 5970 on air. :S

PSU is Seasonic X-1250

Haha it was actually a HIS.
It's now hashing away at 465 mhash/s per core. I prefer seeing the VRM temps in the 80s.

I just got another 5970, XFX Black Edition, with a Koolance block, but unfortunately when I clock over 900 MHz, the VRMs in the second GPU skyrocket. So at 900, GPU 1 VRMs are at like 70, while GPU 2 jumps to 110. Probably just thermal pads or something, but I don't have time for that, so I just down clocked them to 850 and VRMs are below 80.

Personally, I really liked the EK Block on my HIS Card, but the Koolance block on the XFX didn't look to bad.

I was looking around and didn't really see anybody else doing that, so I decided to not push my cards that hard and so keep all my VRMs under 80 now.

Clocks for the 1 ghash/s are on first post.

It would probably be dead slow. Something like 1mhash/s.

Look at how slow CPUs are, then think what a tablet would do.

Tbh, you'd probably spend more money recharging then tablet in one day, then the money you generate from it in 5 years.

Free bump.

Just a question, what are you doing with all of this hashing power?

I actually bought the 5970 with the block already put on, so I don't really know how well it was put on. Then again the seller told me he spent like $200 on thermal pads. Then again, I'm not sure about that.

I'm happy with my 5970 now, it's hashing at around 450 mhash/s, at 1000 MHz, 1212 Voltage.
VRM temps are now in the 80s.

Is this the first time you are doing it?
If not, do you have any people to back you up and say your trusted?

And just out of curiosity, what will you be using these pcs for?

I have my 5970 clocked at 1000 MHz and voltage at 1212. VRM temps are below 100 and in the high 80s now. Hashing at about 465 mhash/s 24/7 for about 1 week non-stop ad I haven't ran into any problems at all.

Maybe your card is faulty, because I ran my card for 3 days straight with the VRM temps in the high 90s and had no issue.

Then again, it depends on what watercooling gear you are running. I've got a GTX 480 Rad with 4 5400 RPM Gentle Typhoons on full blast, so yeah that's why my temps are so sweet. You may ask if noise is an issue, but I have this rig setup in my garage

A general rule I keep for my GPUs is for no temperatures at all to be over 100.
I know that on the 5000 series GPUs the max rated VRM tem is 125, and that doesn't mean 125 24/7, it probably means 125 for a few minutes.

Then I see you have 145C on the VRM.
I'm sorry, but I think that VRM is damaged.

You can try re-pasting etc, but I wouldn't be surprised if the card doesn't work.

Good luck though.

My mobo can fit 4 cards.
Straight off the Gigabyte website, on the page of my MOBO.



Ohh and also, the board layout.


6 PCI-e slots. I think so.

Great mobo, to bad it's running a cheapo Sempron.

Woops, sorry mate just a typo.
I meant 475 mhash/s.

Hey mate,

I use SDK 2.1, drivers 11.12, I installed the SDK via the WinRAR method of extracting and installing only the .MSI file.

Now I'm clocked at 1000 MHz / 350 MHz, and get 475 mhash/s per core.

I leave all my VRM temps below 100 now. 5970 is now hashing at 950 mhash/s and clocked at 1000 MHz. Will VRM temps in the 90s burn my VRMs?

Thanks

Hi guys, I'm wondering if I should drop another $300 to get a WC'd 5970, and actually use my rad.
I currently run a rig with the following specs:
2x 5970 (1 Water Cooled with an EK Block)
1x 5870
Gigabyte 990FXA-UD7
AMD Sempron 145
Seasonix X-1250W PSU.

Watercool gear:
HWLabs 480 GTX Rad
4x 5400 Gentle Typhoons
XSPC D5 Pump Res Combo

Electricity ain't a problem, so just ignore that. I know that the WC'd 5970 pulls about 84 Amps. (Yes it's overclocked) I overclock all my GPUs. So I was wondering if my PSU could handle another 5970 overclocked?
I have a huge 480 Rad with 4 5400RPM Gentle Typhoons screaming away in my garage, so I want to kind of use my rad, but I'm not sure if my PSU is up to it.

Also I am running Windows 7 64-bit, so could I run 3 5970s and 1 5870, all overclocked, on my PSU, and be able to mine on THEM ALL. I hear some people say that 5 is basically the highest because after that it gets unstable, but others say up to 8 GPUs are fine. I'm confused. :S

Pictures:


I have underclocked my WC'd 5970 to get lower VRM temps. I keep all my VRM temps under 100 now.

Any help would be greatly appreciated.
Cheers. (Y)

My PSU is a Seasonix X-1250, a 1250W PSU. It's gold rated.

That's why I decided to post this thread, before I drop $300 on a WC'd 5970 and find out it doesn't work. I only have 1 MOBO, Gigabyte 990FXA-UD7.
:S

Hey guys, I am currently mining with
2x 5970, and 1 5870, (5 GPUs) on Windows 7, 64-bit. I'm using CGMINER.
All is going well.
MOBO is: Gigabyte 990FXA-UD7.

I was wondering if I could throw in another 5970, and mine with that, making it a total of 7 GPUs.
Would that work?

Because I am currently mining with 5 GPUs, 5970's are dual GPU cards.

Cheers

OzCoin have their own widget. Not really a sidebar thingo, but a program.
http://ozco.in/content/ozcoin-widget

Also both links provided on this thread are dead.
If you manage to find a working link, could you please post it here? I would also prefer an OzCoin sidebar, not the program widget thing.

Hey guys,
I just recently got myself a 5970 with a waterblock, and so have that 5970 watercooled, while my other 2 cards, another 5970 and a 5870 are still on air lol.

Are these temps dangerous for a 5970 on WATER?



Overclock settings:
Voltage: 1250
Engine: 1100
Memory: 350

---------------

I am running just a simple water loop just cooling the 1 5970.
Just using some XSPC D5 Res Pump thingo, GTX 480 Radiator (yes I know overkill but got a good price on it), and 4 (yes four) 5400 RPM Gentle Typhoon.

The fans are pretty powerful so I'm not really sure why I get 30C core and 100C VRM. Totally strange IMO.

Just added a watercooled 5970 to my rig.

 

1 GHash/s on a 5970, F**k yeah

Driver version is 11.12
SDK version is 2.1

I installed the SDK by unzipping the EXE and only installing the one .msi file.

EDIT: I changed the OC on the 5870 to 1000 MHz now just to be safe. It's getting ~ 465 MHash/s now.
