What would be the turning point of profitbale in MHash/s vs power input?

I increased my GPU rate from 783mhz to 1,102mhz
BUT
what changed my speed reading is - drop memory Mhz to 425mhz from 1800+mhz

Dropping the memory Mhz also seems to affect the shares in a VERY negative way... [but that could be a mis-report aswell?]

my estimated rewards is dropping too =S

from 35.5Mhash to 21.3Ghash?  With just 1 GTS 450 @ 1102Mhz?

I adjusted my GPU clock from 789MHZ, now running at 1,102Mhz [ram downclocked to 381mhz from 1800mhz]

My GPU is running colder now @ 1102Mhz, then 789Mhz!? maybe im going batsh^t

I did some teaking, now its reporting im processing 20Ghash??  is this a mis-report?  holding at just over 20Ghash!  Thats a huge jump from 34.4MH is it not?!

Using 2 of these on my open 1x slots, and my 2x 16x slots, means I can have up to 4 GPU's on this machine?

Sweet, thanks alot that should help much, however what are extenders/adaptors to make it fit?

I have found several retailers still selling them, one example:

Indeed, I am very serious about mining, and am looking at ATI cards that can produce 24x the mhash performance of my card!  According to the hardware comparision link that was posted - AMD/Radeon 5970 can produce roughly 700mhash/s!  I may purchase 2, however I think I will have trouble with my current motherboard [M4N98TD EVO has nforce n980 chipset].  I may get an equivielnt with crossfire chipset!

I still have windows 3.1 on small dedicated HDD, never use it though unless i need a good laugh.

I had two systems then,

Compaq Pesario
Intel pentium III first version @ 333Mhz
bigfoot 5.2 20gig HDD
256meg SD ram @ 100mhz[the big thing after EDO ram!]

a agp 4x 32meg ATI PRO video card

system had 512meg SD ram @ 66mhz
cyrax 686 @ 533mhz
with riva nvidia tnt-2 32meg agp-4x

The TNT won me over way-back-when

I quit using ATI back in 02 or 01.

However, I would like to ask about quadro and tesla.  Are they better for these tasks then non-commercial grade graphics cards?

They are cuda commands

What they cannot control, they try desperately to destroy.

Hello, I have been having significant trouble this.

Cpu AMD 630 athon II rev2
Ram 2gig 1,333Mhz DDR3
Mobo M4N98TD EVO nforce 980a
GPU ECS 450GTS 192 core @ 789mhz -  1024mb 3000mhz GDDR5

I am using GUIMiner v2011-07-01

I have been mining for 3 days now and have earned 0.02 BTC.
I am processing 35.x Mhash/s
Notice the . please, its not 350+, but 35 .x

I have been trying out some commands to try to boost production, to no avail.

WORKSIZE=128 AGGRESSION=12

I found a post about working command line things, but the reference I used does not display how to set long/muliti commands [so I assumed space without ,]
