If you are going to fly with the Blue Angels, try to get in with either the slot man or one of the solos. This will give you a better view of the formation work as well as a better situation awareness. Flying with one of the two solos would be best because you will get to see the formation work as well as their low level aerobatics. Flying inverted, 200 feet above the deck doing 500+ knots will get your hair on fire.

Wishing you a great rides. Whom ever you fly with remember to tell him when he asks what you would like to do: "I was born to turn and burn". Then hang on for the ride....!!!

I am estimating that it takes 3 GPUs to get into pie, am I right?


Good job all the way around! :clap:

Two OC 7970's on separate machines should do :up:

Sam,

I just about to put in an MSI R7970 OC 1010Mhz on the system below to teplace the 6990. I have BOINC v7.0.36 and plan for AMD CAT 12.11 beta 4. What do you recommend for software & driver versions as well as the optimum number of ATI GPU threads to run...?

Thanks,
Jean-Guy

I systematically load in addition to the latest AMD beta drivers the latest AMD APP SDK, and run 10threads.

I'd run 16 threads with your software & driver & crank that clock up to 1125 :yepp:

Thanks for the inputs Eta & Sam. I will work my way up to 16 threads and an 1125 OC. I will use the AMD 5.11 beta 11, the AMD APP SDK and MSI Afterburner 2.25.

Eta, How was your flight(s) with the Blue Angels? Sure hope that you did not have to use the little white bag....

I forgot that about the clocks. My clocks are also up some to 1150. It depends on the manufacturers. You can go over but then I have long term stability issues wirrh freezing. Some GHZ editions are very good other pretty bad. Jeanguy2 you have to carry some tests on your particular board.

I have not tried more than 12 GPU threads or 1 CPU per 1 GPU. It means you must split the CPU with a ratio of 0.75 instead of 1.0.
With 12 GPU threads it did not give me the feeling that it was making a big difference over 10 GPU threads.
I will check this.

Sam & Eta,

Thanks again for your inputs for the r7970 settings. Just started mine on WCG ATI HCC. Now running it basic with 8 X (1 CPU + 0.125 ATI GPU). Video setting are stocks for video BIOS # 2 at 1010 / 1375 with an idle / loaded VRM of 0.806 / 1.146v to 1.158v. I will let it run like that until the next 00:00 UTC WCG update to insure I do not have errors or invalids. If OK, I will then raise the video core speed to your suggested 1125-1150 MHZ. Here is a couple questions for you guys: With your 7970 at a core of 1125 to 1150...

1- Did you have to increase the video voltage? If so by how much?
2- Have you down clocked the video memory speed? If so to what?

With BIOS 2 selected the stock H7970 efficiency compare to old 6990 overclocked at 950/1250 is quite significant. the average production timing for 8 concurrent ATI GPU WUs has decreased from an average of 14:10 with 6990 to 06:10 with 7970. Power drawn by system under load also decreased from 360W to 255W. GPU temps also reduced from 60-62 C to 50-53 C with a lower fan speed (60% now vice previous 85%). The comp room is so quiet....

Can't wait to see what the 7970 will do with an OC of 4.8 GHz CPU and 1125-1150 GPU...

Left both at stock :)

I have not touched my Bios. I used the Catalyst control center to overclock the GPU and Memory but did not touch the voltages. On some boards memory runs at 1550.
My CPUs 980X one 990X and one 3960X run at 4.0 and 4.2Ghz and compared to the 3.33 Ghz stock frequency it does make a visible difference. If you go at 4.8 then you will see also a difference but to be stable probably you have to play with voltages ? If I move the CPU at 4.8 without touching the voltages it won't work. I try to keep it simple so no voltages. But the DDR3 I make it run at 1800 or 2000 MHz.
Now I tested Sam's config with 16 CPU + 16 GPU threads. The result is much lower than running ten GPU threads and 12 CPU threads. Maybe Sam uses dual CPUs so he has in fact 24 CPU threads available. All my rigs are single CPU.
With 12 CPU and 10 GPU threads settings, my best HD7970 crunch a little over 1 Million WCG points a day, day after day. The average board does 850-920 thousand ppd.
In terms of validated results per day the best boards do 2'335 Validated WUs per day. The average boards do 2'046 WU per day. That is over 10% difference. But the top boards have much faster clocks already from stock, and I could even push them a little more.
As a comparison when running Sam's configuration I got 1'700-1'800 WU per day not a good result.

Good morning Eta,

Thanks for the above post. You have top of the line CPUs. Your data points out that for highest point and # of returns matching the actual # of CPU cores available is best. Some people say that they use the 16/16 config to get higher work time credit when chasing badges. My personal aim is to produce the greatest possible number of validated results. Points are a nice valid incentive but they are not the primary objective.

I just switched from stock settings to 10 X (0.8 CPUs + 0.1 ATI GPUs) which is 2 CPU threads geater than what my 2600K CPU provides for. I will run this for a couple days and then try the 8 X (1 CPU + 0.125 ATI GPUs) to compare results.

Have a great day, I am going to hit the rack for a while...

Not bad the idea of increasing runtime score by multiplying the threads. Frankly I did not much think about it as over sapphire there is not much competition really.
But I wait that WCG implements new badges over the two years runtime sapphire one, then maybe I will change my tactics.

No pie today?

Well, i'm not baking any pie for you gluttons, so here's a copy/paste.

Late pie due to unplanned power outage in neighbourhood. Caused me lots of problems :shakes:

Your pie baking factory didn't seem to be affected! :P

My aerobatic flight ended. Lost my plane.


I am back and very hungry. Hope some pie is left

Now we Know, SAM steals the power from his neighbours :D

Now seriously, that kind of thing can destroy lots of pc and other equipment.

I think it will show today, he has less points.

Just got home to a very cold cave! Yep, another power outage :mad: Looked to have been down for 4 hours. One Mb refusing to boot so far :shakes: Welcome back to Hyper & straight on the cherry I see. Good timing :up:
