On btcguild.com, I click on reset for the worker.
Then, I restarted cgminer, somehow it solves it. It is reporting 1.2GH.
Now I added back the primary pool GPUMAX, and now GPUMAX is also showing correctly.
This is when I say what just happened? I didn't know what I did to fix it.

A lot of pools lately have been doing upgrades/fixes and the hashrate is something a lot of them have been showing wrong until the changes are complete.

I mean...there's two GPUs. One is showing 7.5/m, another is showing 8.0/m. Which is around 15/m total.
Win7 x64, 12.3, SDK that came with it I think, 2.6.5

Ah gotcha. I thought a U:8 was for both!

Glad it's working for you!

What's your U: rate?

7.5/m
8.0/m

What do they mean? I forgot.

U: is how many shares are submitted to the pool. This is the number you want to maximize to get more BTC. Your pool is displaying half your hash rate because you're only submitting half the number of shares you should be! 1.1GH/s should give you around ~15.5/m.

What OS/driver/SDK/CGMiner version are you using?

In fact, I don't think the pools have anything to do with this.
I use the same 2.6.5 version on several machines, and only this one is doing it.
However, I did not add a new card to other machines, don't know if somehow it is not recognizing the shares submitted by the second card??

There's been some talk in the CGMiner thread of newer version leaking a lot of shares to backup pools. How many pools and what version of CGMiner are you using?

Pools calculate your hashrate based off the number of shares they receive. On CGMiner, my single 7970 reads at a constant 652MH/s, but my Ozcoin widget can vary ahywhere from 450-850Mh/s in a 30 second window.

I've got 3 pools total.
Tested with 2 pools but still the same.
Will test with just 1 pool.

One machine with one 7970, cgminer reporting 550MH+, and mining pool used to fluctuate between 450-550MH.

Added another 7970 yesterday, so now it is running TWO 7970. cgminer reporting 550MH+ on EACH card, so total over 1GH.
Mining pool is still shoing 450MH-550MH. Why is that?
Tried GPUMAX, BTCGUILD, DEEPBIT.
Anyone encounter this type of problem?
