So, people have been asking about where all those donations for a 7970 went, and when was I going to get my 7970.

Good news: HOLY GODDAMNED SHIT IS THAT FAST
Bad news: I think I'm going to play Portal 2 again. And Half Life 2. And a few other things. I'll be back in a few years, I promise.

About time...

OpenCL 1.2 is out too. Running it now, same speed as before it seems like.

http://developer.amd.com/sdks/AMDAPPSDK/downloads/Pages/default.aspx

You do realize all that is is an API specification, right? 2.6 was shipping with very beta 1.2 support. 12.2 ships with something slightly newer than 2.6. Do not install an SDK on top of 12.2 for optimum performance.

12.2 is about the worst driver amd has a released in a while. Running the 8.96 driver that comes in that package (12.4). Works pretty well.

Yeah but Linux doesn't have anything newer yet. Although, I gotta admit, I like how my 2.6-ized kernel is performing. 555 mhash at 925mhz. The troublesome part is, I'm going to have to look for new ways of optimizing this, I've tried a bunch of different things that greatly effected performance (both positively and negatively) on the old compilers for vliw5 and vliw4 and it is doing absolutely nothing on the GCN compiler (which is great, mind you, it means the GCN compiler is actually working right).

I am going to be disappointed if all I get is 555 at 925. I wanted over 600.

BTW, they do make redundant PSUs that use 4 or 6 ATX-sized modules meant for 2000-4000 watt blade servers.
I've been picking apart the 80plus certification list, so I'm pretty much certain that I have not missed anything that is 80plus certified. But if you know of something that has good efficiency but isn't shown on plugloadsolutions.com, then let me know. Also I need to be able to get it cheap on ebay Grin

Dude, enterprise PSUs were 80plus a decade before Antec started the 80plus program (which indecently was to attack PC Power and Cooling, their biggest competitor.... and all PCP&C did was affix 80plus stickers to their PSUs with zero changes in design. Sadly, PCP&C was bought by OCZ, OCZ moved it to China, and all the MK II products are fucking shit).

However, I was thinking about something like this: http://www.supermicro.com/products/SuperBlade/powersupply/

3000 watt, seems to use standard sized redundant modules, 4 of them, 250A of 12v, 94% peak efficiency.
Good points. I have actually seen that PSU - it is on the 80plus list under the 240volt section, but I can't find it for sale, at least not at a reasonable price. If you know of a cheap source, I'd be interested.

Try emailing Supermicro.

According to this post, they test the units for a minimum of 12 hours before shipping them out.  I think that's a good thing.

I wouldn't mind if they tested mine out for a few days, even.  If there's a problem, better to catch it before it's shipped.

@Energizer: We do test all the units for a minimum of 12 hours prior to shipping. This is our endurance test
that is done in a harsh environment to make sure the unit is stable and will not encounter any problem in its
lifetime.


That explains that 30ghash user on eligius....

If the 7970 was sub $400 wouldn't the same logic make you think that used 5970s would also drop in price.  I mean all performance is relative right?

Of course with a lack of anything even close to competitive by NVidia I doubt AMD will feel the need to drop prices that low that fast.  Maybe sub $500 sub not sub $400.

Because the 5970s already did drop in price. Gamers are flooding ebay with old cards, irregardless of our little mining community. And no, the drop doesn't happen over night. I'm thinking months as in the 2-3 quarter type of outlook. They will be under $400 before 2013 rolls around.

Well, seeing as in another 3-4 months, people will be able to buy 7970s for $350-400, and ye average used 5970 is around $350-400, and you're not factoring in the cost of slots (ie, switching to two 5870s, which cost of slots would be 2x for 5870s than 5970s or 7970s), so 7970s still seem to win.

Why would people be able to buy 7970s for so cheap if they are such great cards? If they are indeed crafted out of unicorns and awesome sauce, they should fly out of the stores and be subject to the same sorts of availability issues as the 5970 was.

Why would anyone pay such a high price for a used 5970? Just because they are offered at that price, does not mean they will ever sell for it.

But yeah, 7970s are good mining cards. It will be interesting to see how the market reacts.

Because you're comparing apples and oranges? 7970 is the single GPU card, its selling for $599 MRSP. The 6970 sold for $599, dropped to the $350-400 range after a few months, and the 5870 sold for $400 and sold for the $300-350 range after a few months. There is no reason to think the 7970 will also not drop in price.

800mhs ? , you can get ~750mhs at 1.05v on 5890, how can you expect any less than 1ghs on a 7990 ?  I'd aim for 1.4ghs or more...

Because the dual cards tend to be lower clocked and have less powerful VRMs (3 phase vs 4 phase).  A 5970 gets about 1.5x a 5870. A 6990 gets about 1.5x a 6970.  A 7990 then will likely get about 1.5x a 7970.  1GH/s seems likely.  With a heavy overclock maybe 1.2 GH/s.  Then again a rig of 18 cards is never going to be clocked as high as a single GPU rig.

I really don't like your trolling about 5970s ...

5970 easily gets 800 mhash/s in the hands of anyone that is semi capable in OCing and has a brain. Where the heck you get 1.5x Huh A 5870 gets 440 mhash/s so 1.5*440=660 which is incredibly low for a 5970. A much more realistic value would be 750 mhash/s for a 5970.

I don't know what your agenda is but you are probably worried about selling your stack of 5970s once the market is FPGA mostly or trying to get some cheap 7990s or some other fallacy.

I know for sure that the 7990 will get about 90% of the power of 2 full 7970s so 90/100*1400=1260. The 7990 will most likely get 1.25 ghash/s if you know what you are doing. Maybe even 1.3 ghash/s if you are radical a little bit. 7990 will surely get much more than a measly 1 ghash/s for sure.

Except by your reasoning, a 5970 sucks because it ONLY gets 800 mhash, seeing as its a dual GPU board with two 5870s on it vs a 5870 doing 440. Also a 7970 doing 800 mhash uses far less power than a 5970 does and does not have special installation concerns (such as being a bastard that overheats, or requiring powered risers in installations of more than 2).

Yes. All I care about is the $/MHash/s and density while I don't care much about the power costs. I am not one of those "in your mother's basement" folks FYI.

I bet people in Siberia will agree Cheesy It is also about availability as 5970 is not available while you would expect 7990 to be available soon etc.

Using absolute newest DiabloMiner? What hardware and what arguments?
I believe I'm using -v 1 -w 256  (on a 7970)

Those seem to be the correct arguments, so just make sure you're on the newest build. The loss of 25 mhash seems odd.

I need use -na on command line. Without -na i having 35 Mhash/S !!!!! using latest diablominer on 12.2pre with 7970 !!! LOL !

Adding -na to -v 1 -w 256 now gives me normal 677Mhash/S

Uh, yes. You need -na on before 12.2 due to a bug in the driver. You don't need it unless you suffer from the bug because it makes it slower.

Oh yeah you definetely should connect all wires I am just saying it is unlikely you need "a lot" of 3.3V or 5V.  Totally seperate from that idea is the fact that FUTURE (as in a spec) computers no longer need anything other than 12V.  Google runs entire datacenters on custom built servers which have only 12V connections and power supplies which only have a single 12V rail.   Multi voltage PSU are an antiquated design from a bygone era.  They have simply stuck around due to inertia and backwards compatibility.

Thats not entirely true. The way most of Googles shit is ran, they use 48v DC power (which is really 36-48v), they take apart el cheapo UPSes for the 48v->48v conversion, and then they step 48 down to 12, plug the 12v rails right into the 12 line, then use a picopsu to get 5v and 3.3v for stuff that legitimately runs on those voltages.

The future of computing most likely will be 12v and 3.3v only. More and more SATA devices are requiring the 3.3v rail to function.

What I'd like to see, really, is a DC/DC converter block that is outside of the PSU that provides legacy connections, such as 5v/3.3v (and pass 12v straight through) for drives. So, say, 4 SATA power plugs that plugs into a 6 pin PCI-E and does the DC/DC conversion in line.

Incidentally, is it possible to pass out different arguments to different cards on the same machine?    In case I find a cheap card to throw in addition to my existing. Smiley

Not yet. You need to run multiple DMs at that point and use -D to select them (like, one 7970 and two 58xx? -D 1 on the first one, -D 2,3 on the second one).
