Stream

Very interesting to see some projects supporting these video cards. I would like to see some boinc projects doing this as well. It seemed pretty straight forward on the install. I'm just not to sure on the stats and user account. It looks like I have a while to wait to get added to the stats so I can edit my profile. I watched my GPU hit 70C when it was running over 97percent activity with the fan at 100 percent. It looks like I would need a liquid setup to keep this 4850 cool at 90+ GPU activity

Thanks for all the great info on this project Brucifer. It looks like your gonna be moving up the stats pretty fast hitting number 18 on the daily stats today.

I just let them run. The 4850 isn't running any warmer than the GTX 260, and it puts out double the work on rc5, and much less current draw too. It's a good card, and I will buy more of them I think and get rid of the other stuff I've used for rc5 and save a bit of electricity too. :-)

@liuqyn -- what are you running on rc5??

[liuqyn]

ran a little on my laptop last week(IGP HD3200 roughly 5-6 Mkeys/sec), then one batch of cuda on my GTX285 triplets (combined roughly 700-800 Mkeys/sec). currently not running.

Hi

Found this board by googling, one of the few places I can find where people are discussing RC5-72 and the graphic accelerators to power them.

I'm having some amazing results from the new 2.9108-517 client (released mid-March 2010) versus the 2.9108-516 client.

I am running a stock 5850 and have seen my keyrates increase from ~966Mkey/s to ~1,420Mkey/s. The release notes for the client indicate it now has a faster core for HD5xxx cards so I'm guessing all sorts of benefits could be had even on the cheaper units. Given I'm getting a 50% boost, that's pretty impressive.

For reference, the GTX260+ (factory overclocked) in my old PC still only manages a (relatively) poor 245Mkey/s. Although after years of crunching on the CPU and thinking 15Mkey/s was awesome, it does seem weird to criticise the GTX260+ for its 'weak' performance.

LOL, yes I hear you on the GTX-260. I've got one sitting on a desk top because they suck so much juice and put out a ton of heat. I'm running a 5770 in place of it. It isn't super fast either but it sure doesn't put out the heat and is twice as fast as the 260.

Now if they would finish their testing on the database and get it back read write, so I could get my primary rc5 account back under the team, things would be great.

The problem with the newer cards is that the prices of them just shoots way up beyond reason, and then a year or so later it is like a third of the initial cost. I have one lowly XFX 4650. It doesn't put out like the big ones, but it cranks out about 2,880 units/points a day running on a 450w power supply so it doesn't suck down much juice. That's like 1,051,200 units a year out of that one little card. Still just knocks the socks off any quad out there, and much much cheaper to purchase too. :-) And while it doesn't put out like my 4850's, it is still a pretty marvelous item when I look back several years to when I was running a herd of processors and getting much less that the 2,880 units a day. We get pretty spoiled on performance now days and forget what the performance leaps are in a short time span.

My 4850 runs 9,600 units a day or 3,504,000 or so units a year, over three times what the xfx 4650 will do. So those gpu's are definitely worth their weight in gold when viewed from a cost versus output perspective. Much cheaper than buying new cpu systems. So they are the way to go for crunching rc5.

My GeForce cuda systems on the other hand are much slower than the ATI systems and suck down much more electricity too. However when compared with what the cpu systems put out, the present cuda systems still are impressive items. It will be interesting to see what the next generation cuda stuff does, and what Nvidia is going to charge for them too.

I have taken my rc5 crunchers and put them on collatz for the time being. When rc5 gets back to allowing the user database to be edited then I may bring them back here, unless of course the dark side gains control of my dc addiction.......

Sigma,

I've found the completely opposite. I was using the older client on my 3850 (or whatever I have - I forget!) and it would fly along but with the new release, it's broekn and I get nothing. Seems to download everything fine but no progress. Maybe I didn't leave it long enough but I with the new client, I cant use it at all.

Major shame.
Means all I get is about 50 units a day whilst at work (one core of a T9400 @ 2.53GHz as I don't want to overheat my laptop).

[Brucifer]

Are you still crunching with the older release somehow???? Cause that will not register any completed units. You must use the new release. Somehow you got them mixed up?????? The new release from the distributed.net download page works for both stream and cuda....

[drezha]

I download the new release (v2.9108.517) and I get nothing. I select a manual benchmark and it goes through that and chooses the IL-4 Pipe alt C.

EDIT:
Anyhow, whilst typing this, I set up another instance and it appears it takes about 3-4 minutes to get itself going. And now I have it's showing about 19,000,000 Key/s (which seems a bit pants considering my CPU at work kicks out 9,000,000 Key/s per core IIRC)



As you can see, it troughs and peaks a lot
