Topic: What's your Mhash/s? (Pissing contest here) - page 19. (Read 143998 times)

I have 3 reference 7950's for 1,500 Mh/s  I run them a bit slower so they will last longer and the fan runs slower too at ~52% speed for 68c.

Haha, that's a nice one 

~1.7GHash/sec on my mining rigs consisting of 1x4670, 1x4770, 1x5770, 2x6950 (unlocked shaders), 1x7970.  The two first are in a computer at work, the three others are in a dedicated mining rig, and the last card is in my gaming rig.

1000 Gigahashes a second

I'm doing 500 MH/s with an undervolted 7950. I would push it harder in terms of voltage and core clocks, but I'm trying not to blow up my power bill by running the A/C too much.

what kind of gpu you use? and how many of them 

I'm at about 8,000 MH/s currently.

have anyone try the BIOSTAR HD5850?
because when i read, seem like there is no one using this brand
is it same this biostar with the other brand like sapphire or the other
this is the card link

I'm running two (apparently) voltage locked MSI 7950 cards using mostly scrap hardware from previous gaming rigs. I've been mining WDC for the past few days and playing around with my numbers in order to get a decent accepted/rejected ratio relative to CGMiner's reported hashrate. With my intensity dropped down to 18, I'm getting 640 KH/s on each card with ~4% rejects:

4.2 mhash (scrypt)

  I'm running so slow

133mh/s and waiting for a hd 5850 that I just bought on E-bay that should give me 350mh/s once overclocked.

I'm trying to understand why so many are selling their top mining rigs... is it to buy asic or just to stop mining and buying btc instead !??

4x 5850 at 280mhash each running with seasonic x660

I was wondering whats a good gpu replacement for these (gg out of warranty soon)
i want to get 1gig hash at least from a 660 watt psu.
i've noticed that triple 7950 can go up to 700 watts thus needing a 750w and above.

Hi, I have a rig with four VTX HD 7950 shared with a friend. Well, we bought 5, but one of them failed because a broken fan.
We get about 530 kH/s on each GPU mining Litecoins, totaling about 2.1 MH/s. That produces now about 4 LTC/day.

We re using Windows 7 and Guiminer-scrypt with cgminer configured for mining. Motherboard is MSI Z77A-G45, and CPU is Intel G1610 (the cheapest Ivy Bridge 22nm). We have 16 MB of DDR3, but we only need so much memory when we use "reaper" instead of "cgminer". We use active raisers for 3 of the 4 GPU's, and we use 3 power units TACENS of 850, 850 and 650 watts.

Our parameters are:

  gputhreads = 1
  worksize = 256
  intensity = 19
  thread_concurrency = 44800

You can think that it is a big thread_concurrency, but it is what maximize the use of the 3 GB of each GPU:
  64 x 44800 = 2867200 kB,

that is very near to 3 GB, and it is a multiple of the number of shaders per GPU = 1792
  44800 = 25 x 1792

If we try a higher multiple of the shaders, the computer hungs. If you use a low value for thread_concurrency, you will get good khashes, but few accepted shares, so you don't get so much coins. I mean that khashes is not what you must maximize, you must maximize accepted shares. For example, with td = 1792 you will have the same khashes, but almost none accepted shares. But it is a good parameter value to try overclocking, as the responsiveness of the system is faster. By the way, we are using a bit of overclocking, with core/memory clocks at 990/1320, and we get temperatures about 65-70 ºC (with additional big fan).

Our percentage of stale shares is very low, about 1%. We use Netcodepool.org, we are "cqcoin" there.

I hope that this will be useful to somebody.

1 x 7970 at 700 Mhash
2 x 7950 at 600 Mhash

Oddly enough, getting them to all run decent hash rates at the same time has been a PITA. Going to build a 2nd machine with just 7970s.

xfx 6670 @ 110 m/hash

xfx 7750 @ 125 m/hash

Two systems combined in at a hashing speed of 235 m/hash

Two 6870s from ebay should be arriving any day now.

what is your temprature? I almose burn my house, damn

Which 7970 do you have?

I have four Gigabyte 7970OC doing 730kh/s per card.

3x7970 @ 666.7Kh/s each. Total is exactly 2Mh/s. Kind of disappointed though, I've seen many people get theirs over 700. I've struggled just to get it this high. AVOID GHz ADDITIONS!!! AFAIK, they all require a BIOS reflash on linux. Dunno about Windows machines.

... I can only CPU mine at the moment. Looking to invest in either FPGA or ASIC solution, though. Recomendations?
