Before the two Day Outage i had on every Rig up to 100 -9 Errors.
Even on Rigs they don't changed since month. Some WUs were validated
(Wingman had it also) some became invalid...

A loooong time ago: First Credits after SETI@home Restart

Okay, all installed and running happily. First task just finished. Run time 22 minutes and 33 seconds. http://setiathome.berkeley.edu/result.php?resultid=1784680949 GPU temp is showing at 55C with the fan at 50%. ~60% to 90% GPU usage. Core clock at 822 shader at 1645 and memory at 1804.

At one wu at a time I was finishing in about 18 minutes, two at a time was about 33 minutes, and three at a time is about 53 minutes per wu. That is with slightly overclocked settings for the three at a time - 900 MHz core and 1800 MHz shader. 93%-95% GPU load.

Thanks Tazz, I doubt I'll try three at a time but I am trying your OC figures. I just changed to them so I don't know what kind of a speed up I'll get yet. So far everything is looking okay, not much in the way of validations yet though. Guess I will go ahead and change to two at a time and see how it does.

Mine is factory (Asus) overclocked to 850 MHz, there is also a 925 MHz version from Asus, but I'll stick to 900 MHz for now. I think I'll drop back to two wu's at a time too, to take some of the stress off of the card.

Mine is an EVGA that came with a slight overclock of 822. 900 seems to be running ok and have just started running two at a time. Doesn't seem to have slowed it down very much but I've been getting some strange times on the work I've been running right now. With the replica database running behind, the validators far from up to speed and work giving me all different times it's hard to figure out. All I know for sure is that it is a lot faster than the 9500GT I had in there.

it is a lot faster than your 9500....the cudas take 23 minutes to do....and i get 100 points for each one.....i have the evga 450 and it is fast...i hope you looked at the bench marks for the nvidia cards i posted here.....there is no comparison between the cards

:)

my RAC went from 4000 or so to 12000 with this card

:)

http://www.hardwaresecrets.com/article/NVIDIA-Chips-Comparison-Table/132

gtx 450 is about 4 times the card the 9500 is

:)

I have one 460 gtx at 800 core clock
Running two wu at one time on this gives me a 95% load on gpu.
3 wu is far too long (1 hour to complete 3)
26 minutes for two so 4.5 / hour
12000 rac extra

I find 3 wu is too much for this gpu
The ram makes the difference
768 meg on the Zotac 460 gtx = 2 wu
1 gig on 460 gtx = 3 wu
1.5 gig on 460 = 4 wu at one time

Make sure you are crunching 6.10 fermi wu

Those are my observations

M. Miles

I have an Asus 450 ENGTS 450 DirectCU/DI/1GD5
EClk-783
SClk-1566
MClk-902 (3608)

Actually, I just grabbed what I have which is Valid results and put the data into a spreadsheet.

It shows with a mix of various AR's my average time for completion is 1,038.60 seconds = 81.45572586 Results/day at the granted credit rate of 98.89 = 8054.973871 credits/day.

As always Eveyones milage varies.

I hope you folks get better service from your 450 than I have. Mine just blew chunks.

I have an eVGA 450 - the faster clocked 1452 model. I was out of the room and when I came back the pc had rebooted (sitting at the login screen) and there was square blocks of snow zipping around all over the screen. At first I thought corruption, ok, no biggie, reboot and it will clear.

Nope, reboot ok, but never get to a stable windows environment. And snow or some kind of interference everywhere.

Pulled the 450 out, put the old 7600 GT back in - boots into xp fine (except Nvidia driver can't handle a card change smoothly). Pulled that card out and put the 8800 GTS 512 in and after rebooting and letting xp and the vid drivers reach an agreement, rebooted again and now crunching on the gpu again.

Tried calling Micro Center twice but no humans available.

The card was purchased on Dec 24. Running out of time...

edited - ps The card was not oc'd and running 1 wu at a time.

owchee....that sucks.....sorry to hear that.....mine is running fine so far

edited - ps The card was not oc'd and running 1 wu at a time.

So, that's what happened, the card felt neglected! :-)

I've only had mine for three days now but everything seems to be running smoothly. Little bit of an overclock and running two at a time. Times seem to be around 35 to 45 minutes per WU now with two at a time. I'm happy with that! :-)

your RAC is coming up

:)

RAC is up!? Great! :) I don't think it will go too far, the 8800 is a bit slower than the 450 was on midrange wu's. The workunits I have here now Ready to Report are all showing about a 26 minute total run time, which is slower than normal for the old card. It's normal run time is usually around 22 minutes and the 450 was clicking them off in about 18 minutes or so.

The added time may be because it is now doing video chores, too. Before the 450 came along, the 8800 only crunched and the 7600 GT drove the monitor.

I may revert to that config again as the 8800 is noticeably slow on video response when crunching, too.

8800 looks to be a equal for the 450 on the comparison tables

All things being equal, it may be. The 8800 in the machine now is a stock clocked PNY product. The 450 was a factory overclock.

But, the 450 has more going for it than just CUDA performance. More memory and multiple power profiles make it a better all-around performer. At idle, my pc was drawing just 85 watts with the 450 in it. The pc draws at least 125 watts with the 8800 in it. At full crunch the power draw is about equal - 220 - 225 watss total from the wall outlet (e8400 cpu at 100% crunch also).

The 450 crunches VLAR's with barely any slow down at all (most of the time) and it's fan is much quieter and needs fewer rpm's to cool it than the 8800's fan does. The 8800 has occasionally experienced a severe problem (lock-ups/reboots) with VLARs. The different response may have more to do with the different CUDA drivers from Lunatics (the old V12 vs the current x32f) though, so I can't be sure yet if it's the card or not. We'll see what happens as the 8800 continues to crunch and eventually finds a VLAR to chew on. I'm still using the x32f driver even though there is no Fermi card available at the moment. Still using DirectX 9.0c, too (it's all XP can handle, I think).

All around the 450 is a very attractive card. I hope it doesn't take too long to get a working Fermi card back into the machine.

your RAC is coming up

:)

Yeah, it tends to do that when I get a couple of APs validated. :-) Looks like my newer work is finally starting to validate too though so I should see it really start to jump soon! Up until yesterday evening all I was getting validated were ones where I was the third (or fourth) to turn in a WU. Settling inconclusives for others. All my work so far has been good, only one inconclusive where I was paired with a fermi card running V12.

Running low on work. Just moved a handful over from the CPU to the GPU. Haven't had to do that for quite awhile. Mostly VHARs so they should disappear fast. At least this will give me an idea how well moving work units is handled. :-)

Okay, first shorty finished in 24 minutes and 35 seconds. reported and validated already! Went ahead and moved the rest of my work units to the GPU so it will have a little more work to do.

Started hearing a loud fan noise. Shut down and opened up the case. Found a small piece of plastic hanging down from my 450 with a message on it saying remove protective film before use. Oops!!! Got a bunch of work validated since we've been out of work units to crunch. Looks like my wingmen have had a chance to catch up to me. Everything so far seems to be doing fine. Now, if only I had some work to crunch!
