share your hashrate with system specs. compare with others.

I'm running an AMD radeon 6990 overclocked to 950Mhz and getting about 365 Mhash out of each core. i cant seem to overclock it past 950Mhz though without it crashing after a few minutes. i'm useing MSI after burner to OC. anyone know something i dont?

check your cooling, make sure you have the required voltage, and make sure its your videocard crashing. not saying it isnt, just know that sometimes ram crashing has been misconceived as being the fault of the videocard by people in the past. but really just make sure it cool enough to handle the heat, and that its getting enough juice. by the way you explain it, im thinking your issue has more to do with the heat.

I wish I could mine but my PC was just giving me about 3m/hash...will not do

Thanks, i'll check out the specs on it as far as heat range but i know the fans are set to auto and have yet to go above 80%. if i OC between 950Mhz and 960 Mhz after about 5 min Phoenix crashes from 960Mhz to 970Mhz ish i get a your 'graphics drivers have stop working' something like that 970Mhz to 995Mhz i get a few screen flickers and than that message above 995Mhz i have to just restart the PC.

4 GPU on 3 machines:

2x Nvidia GTX660         ~72Mhash/s each
1x Nvidia GTX660Ti       ~97Mhash/s
1x Nvidia GTX470         ~85Mhash/s

Never got into ATI for gaming so I'm using what I have !


EDIT: no tweaks, no OC on any of the cards. I played with it but 5% more mining wasn't worth the concern of running my cards too hot.

I'm hashing at 290 MH/s with 6850

[kisshu]

2.26mh/s... ehrr lowers better, right???

LiteCoin mining at minelitecoin.com is giving me accurate kh/s readings compared to what my kh/s readings are on cgminer.\

With the 7870, I am pulling in roughly 280-330 kh/s but I have seen some members get their 7870s to over 400kh/s. (I have not tinkered with overclocking)

If anyone could help adjust my settings in order to get higher kh/s, please help a friend out!

Currently using -

--scrypt --thread-concurrency 8192 -o http://minelitecoin.com:8336/ -u withheld -p withheld -I 13 -g 2 -w 256

[Signus]

7950 + 7970 = 1300Kh/s.

Do you mean 1300MH/s? A single 7970 on average can do over 600MH/s, and a 7950 can do 400-450MH/s.

Those two cards combined should be able to spit out at least 1GH/s.

And here I am CPU mining LTC with an old server. =P

2.26mh/s... ehrr lowers better, right???

lol no. lower is not better. its the letter next to number that really matters. if its Mh/s you want high number. you still want a high number if its Gh/s but your not likely going to be getting about 100Gh/s without a really frakin awesome asic setup. with a pc. shoot for 2000Mh/s or 2Gh/s (both mean the same)

Seems to me that mining is fast becoming an inefficent and expensive way of obtaining bitcoins.  More and more resources will be requried to mine less and less bitcoins.  So why keep trying - wasting money and energy?

[ArcologyPrime]

Video Card mining, at least for my cost of electricity, is still profitable in the short-term at the current prices. Litecoin mining is always an option, too.

Windows 7, GUIminer, ASUS Crosshair IV Extreme Motherboard, 850 watt PS, Three XFX HD6870 video cards each at an average 280 MH/s= 840 total MH/s. I feel I could get over 300 MH/s from each and lower the power consumption if only MSI Afterburner would ACTUALLY underclock the memory. Have UOC enabled and memory set at 324 MHz, but it stays at 1050 MHz...

Two other rigs running also, one with two 5770's, and another with one 5770. They are getting 202 MH/s each and the memory is underclocked with MSI Afterburner and working correctly.

Total hashrate with all three systems is 1440 MH/s. Mining on 50BTC pool.

undervolted SAPPHIRE 7950 x 2 ~550kh/s each = ~1100kh/s (LTC) cgminer 2.11.4, catalyst 13.1, its about the same with sha256 = ~1100Mh/s

[keepinithamsta]

I'm running around 3Ghash with five 7950's.  4 of them are able to run at 1150/800 clock speeds and one is kind of limping along at 1080/800 in another computer.

[Amleth]

~2GH/s. Will go to ~2.4 when I can find an old DDR2 770 board with two PCI-e 16x slots with decent spacing.

[Firestarter1]

Two 7770 @ 195 MH/s
And sony vaio z with astonishing 65 MH/s.

Still waiting for pci-e extenders to ship, to start being badass. 

[joffrey]

74 MH/s on a 6750M, with DiabloMiner.
