Has anybody ever noticed that the pre-populated nVidia stats all assume (regardless of generation or architecture) it would take 6640 cycles to produce a hash?  I know there aren't many nVidia owners out there mining, but if any of you are reading this, add your stats to:

https://en.bitcoin.it/wiki/Mining_hardware_comparison

I've added my results under GTX460 (2 cards) OC and noticed that a stock clocked 460 had a higher hash rate in the table than one of my overclocked 460's.  Just to let you guys know, I'm getting hashes roughly every 8570 cycles versus the 6640 the table assumes.  I also find it a little amusing that the hash rate assumption was applied to a 9800 as well as a 580, even though their architectures are radically different.  I've said this already, but...  If you've got nVidia hardware and have some stats, add your results to the hardware comparison.

Actually, there's probably not too many nVidia miners left.  Is anybody actually going to read this?

It's a wiki, you can add it yourself! (And that would probably be wise - I suspect you two may be among the few remaining Nvidia miners :-)

I'm running an 8600GT at 7.3Mh/s
2Mh/s better than the ones posted on the wiki  Grin
GPU shark says 43 watts so it's 0.169 Mhash/W if thats correct
using poclbm with -w 128
1602 MHz shader clock

jkminkov, not everyone would want to sign up to add a single entry of dubious value.
If I have anything else to add to the wiki I'll sign up. but shit stats for the 2nd shittiest card on the page ... not just yet thanks

I don't want to sign-up.

560 is one of the newest Nvidia cards and it is missing, dubious entry is better than no entry at all.

GTX480>GTX560>=GTX470

I'm using a GT 240.

Using python poclbm-mod.py -d 0 -f 0 -a 10 -v -l, I regularly see between 21230 and 21255 khash/s.  I've also noticed that -v (vectors) costs about 300 khash/s (21567 to 21579), but I think there was an increase of invalid/stale shares --- this may have been due to other factors, however.  I also think there was a reduction in discovering multiple shares per getwork without vectors, but that may have been due to the same 'other factors'.

I don't know what the wattage draw is, but I have noticed the temperature of the card jump from 58 (idle) to 72 (mining).  I'm guessing these values are in fahrenheit.

You would be guessing wrong. I idle around 50 and can hit 90 under load if I push it hard enough.

If they were in farenheit, youd have the coldest GT 240 on air lol.... mine is that - 5~6 degrees Celsius because I redid the thermal paste

I didn't know that applying power could cause a card to refrigerate itself to below room temperature!

I already saw a computer INSIDE a mini-refrigerator Cheesy not very good with Computer power/W though as the refrigerator was basically working at 100% load all the time

add my former card

Nvidia GTX560 Ti, factory overclocked to 900/2000

86700 hash/s

win7 x64 and RPC Miner CUDA

OK, well, I guess I'll add it.  Some more info wouldn't hurt, but there seems to be just enough here.

I'm running an 8600GT at 7.3Mh/s
2Mh/s better than the ones posted on the wiki  Grin
GPU shark says 43 watts so it's 0.169 Mhash/W if thats correct
using poclbm with -w 128
1602 MHz shader clock

The wattage is going to be off by a pretty good amount.  If you go up by one model, the 8600 GTS has the same GPU clocked at 675 MHz core/1450 MHz shader clocks vs. the 8600 GT at 540 MHz core/1180 MHz shader clocks.  The 8600 GTS is listed at 75 W.  If your shader clocks are 1602 MHz, you're probably in that 75W or greater ballpark, which reminds me...

I idle around 50 and can hit 90 under load if I push it hard enough.

The cooler for your card was designed with a 47 W TDP in mind.  Pushing those clocks may not kill your card today or a month from now, but it will definately shorten its life.  Your card being an 8600 GT, you may not be all that concerned, anyhow.  I'll add it for now, but let me know if you are running a different clock than the one you have posted.

My computer jumps between 18.7 and 16.8Mhash/s on my 9600gt

More information would be helpful.  Is this card running at the nVidia reference clocks?  What miner are you using?  What command line arguments are you giving it?  (omit username and password, obviously)  The speed variance your seeing is somewhat disturbing.  Is this happening while you're not using the system or is 18.7 MHash/s consistent while you're not using the system?  Also, fire up GPU-Z to determine which specific GPU you have, as there were two versions of the 9600 GT, one based on the 65nm G94 and another based on the 55nm G94b.  I've seen wattage specs for the 65 nm part, but haven't run across wattage specs for the 55 nm part (which would be lower).

I'm using a GT 240.

Using python poclbm-mod.py -d 0 -f 0 -a 10 -v -l, I regularly see between 21230 and 21255 khash/s.  I've also noticed that -v (vectors) costs about 300 khash/s (21567 to 21579), but I think there was an increase of invalid/stale shares --- this may have been due to other factors, however.  I also think there was a reduction in discovering multiple shares per getwork without vectors, but that may have been due to the same 'other factors'.

I don't know what the wattage draw is, but I have noticed the temperature of the card jump from 58 (idle) to 72 (mining).  I'm guessing these values are in fahrenheit.

nVidia specs this card to run at 69 W.  Also, try to determine if this card runs at nVidia reference clocks.  GPU-Z should do the trick, as well as CPU-Z (Graphics Tab, highest perf level).  As far as you're -v issue goes, you may have just had a run of bad luck.  Who knows?

I'm using poclbm_gui with -w128 -f 1 flags and stock settings of 675/900. I set my card to 800/650 and I see 20.1 Mhash/s but it still bounces around so it is hard to get an exact reading.

OK, well, I'll put up the two stats you have for your 9600 GT, but I'm going to leave the wattage field blank without the specific GPU chip that's on that board.

Actually, I'll need the shader clocks for both of those settings to make a good entry into the table.  There are three clock speeds for these types of boards.  It appears that you've passed me the core and RAM clocks, but not the shader clocks.  Stock for a reference 9600 GT is 650/1625/900 core/shader/RAM clocks.  Also, I'm still going to need the specific GPU chip if I'm going to add to the wattage and Mhash/W fields.

Sorry I was using nTune and it doesn't say Shader Clock in there. I have it overclocked now. Riva Tuner says this:

G94 chip 799 Core 1981 Memory 651

GuiMiner says I'm getting around 18.8 Mhash/s now with -w128 -f 10 so I can use my computer. I tried different values for -w but 128 seems to be the best.

OK, I'm guessing 1981 is the shader clock.  Something got a little convoluted in there.  I'll go ahead and put that up.

i am posting this from memory as my tower is at my parents place.

getting just over 30k Khash/s with 670 core and 999 mem (dont remember shader) on a 8800gt

with stock clocks i think it was some where around 26k Khash/s

using -v destroys the hash rates giving about 17k Khash/s no matter the clocks. Have no idea why this is

-v kills hash speeds on my 9600gt too. are there any nvidia cards that work with -v on?

So is there any poclbm flag adjustment to be made for the nVidia's ?
