DeathAndTaxes has an all out watercooling 5970 set up, or at least he did. You should check out some of his build pics.
Cooler is always better for electronics parts.
Topic: 5970 - 1 GHash/s - Bad Temps? (Read 4460 times)
I was not aware that 1Gh/s was even possible on a 5970... That is just outrageous hashing power for an old card...
Mine would only do about 700Mh/s a piece...
Yeah that 1Gh/s is pretty damn impressive.I just wish I could buy an HD5970 easily in UK (it's out of stock everywhere in UK) and reach those clocks (although I should factor in the cost of watercooling that monster as well). Impressive.I wonder what the power use is and what your PSU is rated at? As you'd need a pretty strong PSU to run that and a watercooler plus the rest of the system.Mine would only do about 700Mh/s a piece...
PSU is a Seasonic X-1250. I'm thinking the system itself is pulling more than 1.2 kW from the PSU, but I don't have a watt meter to tell.
It's a great PSU, everybody was recommending that over a Corsair AX1200. Also, I wasn't sure if the AX1200 could support 8 Pci-e cables, because it comes with 6 (as said on website), so that would limit me to 3 cards. While my SS has 8, so up to 4 cards.
Great PSU - best I've seen so far is the Enermax Platimax 1500W - 10 Pci-e cables with that one
If I didn't worry about them being obsolete soon I'd get 3 7970X2 cards and one of those and have a little 3.8Ghash box

PCI-E power splitters and molex/sata > pci-e power adapters are your friend
Sometimes it's just safer to use something which is designed for what you are going to do. And you obviously can have risks using to many power adapters, I think I saw one guy fry a molex adapter.
But why economise a few bucks to risk any additional issues? I went out straight to a SS so I knew that I wouldn't have to touch the PSU again. And it's still there running 24/7 for 1 month do far.

I was seriously impressed of your 1Ghash/s and I would like to know which brand is this 5970?
Is it XFX Black Edition or something or just a reference card?

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.

I'm running my 5970s on air and my vrm are under 100c at 900mhz and 1.1v
If you are on water and can't get it stable it's because you farked up your water block install or used poor quality TIM. Yes it really is that important. It's needs extreme thermal conductivity and the proper thickness.

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.

It wont help.
I got 7 and that situation:
engine 750, mem 150, 1.05 vcore - DEAD every 3-4 Days and red liight on VRM every 2-3 weeks.
5970 Is watercooled, and max temp on it is 55.
I was using once 5970 with 1100 engine at 1.2 Vocre - temps had 45, and 90 at VRM - after 1h of crunching(boinc) i had hard hung.
It takes large amounts of power. VRM cant take it for a long run.

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

get better tim for the vrm's
needs to be >=6w/mk

Your VRM's will burn out.
Eventually you will see your hash rate fluctuated by 50 or so m/hashes
Once that happens your card will burn out in a couple of weeks or days.

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
You should be alright I think...
What's the power draw on that thing?
My VRMs are all running under 100 C.
That shouldn't be a problem running 24/7.
Then again, why should I listen to you, you do have scammer written all over you. (Nice guy that is)
Tell me if the VRM was rated for 24/7 BTC mining ( which is known to force VRM and even power circuits in FPGA to extreme limits ) ?
NO. It is rated for 125 degrees for a few seconds mostly but not 24/7 at all.
Let us know when your card is fried and you can't even game on it anymore due to overheat and damaged components in that area !

Exactly.
But let him push his 5870 to 500 mhash and his 5970 to 1000 mhash because then lower difficulty for ME !
So this dood is getting 470 on 5870 and much more than 2*470 on a 5970 ?
I thought 5970 < 5870 * 2 ?
Whatever, it is his wallet he will burn ... we have warned him.
I suggest OP try for 1100 MHz clocks and 1100 mhash next !
