Don't even waste you time on Mining.
Mining is DEAD, with all the ASIC units coming out in the last few months it has become unprofitable to do so.
You could invest $50 for an Erupter that will give you 336/Mhps, it will take you around 2 years ATLEAST to get your money back.
Example:
I have been mining with one Erupter, I have so far made BTC0.06 ($6.00 USD) been mining for 1 month.
Topic: Why do I only mine at 3.3 Mhash/s (Read 6185 times)
What video card is that ? model etc ? seems interesting
thxAnd about switching to AMD, when you have 3 different videocards in one computer, sometimes the drivers are not compatible and some won't work, or work properly. So that's why I'm not going to risk screwing up the delicate balance of my three Nvidia cards powering my 6 monitors.
Um welcome to the 21st century they make graphics cards capable of powering 4,5,6+ monitors. Still if your computer has no PCIe there is no point in upgrading. Really the lifespan of GPU mining is probably very limited at this point as ASICs will eventually push them out the door so you likely aren't missing much.

thxThen you are using a terribly inefficient and old CPU mining program. I get 3.9MH/s per core of my non-overclocked 1090t.
(I used pooler CPUminer 2.2.2 64-bit.)
(I used pooler CPUminer 2.2.2 64-bit.)
True, my CPU is not a top-notch one anymore, but hey - even your CPU is just at 3.9 mhash/s. Compared to 370 mhash/s, this is a ridiculously low value when you compare CPU vs. GPU in general. If your gfx card is a slow one, and your CPU is doing better - stick to it. For me my GPU is more than 100x faster than my CPU.
Yep. CPU mining is not worthwhile but I am just pointing out it is not as bad as people make it out to be because typically those people haven't used modern CPU miners.
As a comparison, the Radeon 5450 overclocked will get about the same as the 955... while using 1/10th the power.
edit: just re-read your post.
I also notice you are not at all familiar with CPU models or what a core is. I am not going to go into detail but suffice it to say, My CPU can do 3.9 X 6 = 23.4MH/s minus any inefficiency loss for multithreading (I have noticed there is some in CPU mining). Also, the cores in your CPU and mine are the same. I am indicating that your CPU should be able to do 15.4MH/s minus any multithreading efficiency loss.
I may try to mine some litecoins as well..sounds good.
You should start mining LiteCoins since it's more profitable.
Here's the list of pools http://www.askminers.com/mining-pools-list
But I suggest notroll.in for startder since you can withdraw at 0,1 LTC and that shouldn't be a problem even with that computer.
You can later change LTC for BTC and in the end you'll have more BTC than you would earn by mining them.
just my 2c

Mine Litecoins. Neeeeext. Wow newbie area is fun.

I have an 1090T too. That would be 23.4MH/s, which is something but I think isn't worth the power. GPU's are a lot more cost efficient. My Radeon 5750 gets 140MH/s with probably about the same power use as the 1090T would take. (That said, I haven't tried measuring actual power, and it's possible to undervolt the 1090T significantly.)

how is it possible that many ppl try mining on notebooks? you cannot get a good cooler on it. am i wrong or its a fast way of burning your board?
My GPU running at full tilt in my laptop (radeon 6770m) doesn't significantly heat up the laptop. And this is an HP we are talking about (they have a terrible corner cooling design).
My CPU, on the other hand, running at full tilt would kill my laptop through overheating (i7 quad, 90+*C and throttling when H264 encoding).
My board will not burn if I just run the GPU. Even overclocked to 850MHz, pulling 110MH/s
My actual concern is the longevity of the battery. When I mine for more than an hour or two, I take the battery out.
So you can't generalize all laptops but I recommend making sure the temps are reasonable (GPU-z and core temp - check both as most heatsinks are combined GPU+CPU) and always removing the battery if you intend to mine for more than a little bit.
Just a comparision of my setup:
AMD/ATI XFX Radeon HD5870 vs. AMD Phenom II X4 955 BE
GPU: ~370 mhash/s vs. CPU: ~2.2 mhash/s
Conclusion: Mining on a CPU is useless.

Well they're not really aware of the differences between CPU's and GPU's, and people want was is convenient to them.

I'm in a similar boat.
The mining hardware table looks to be very useful.
Will have to invest some more money!
I just grabbed an AMD 5970 on ebay for $400. it gets around 800Mh/s Not as amazing as some of the miners numbers but better then 95% of single GPUs on the market. Sure it's pricey for it's age but the best part is I can use it for a couple months and sell it back for 80-100% of it's value The mining hardware table looks to be very useful.

You definitely need and upgrade, and 8400 definitely can't do any better than that.

I believe the ASIC miners can only do SHA256 and won't be able to mine LTC. So, your GPU should still be OK to mine LTC (for now).
you better upgrade your graphic cards and mine LTC at the moment, book for an ASIC and mine with it, once ASICs hit the network, GPU mining won't be profitable considering the power and cooling costs, GPU still profitable for LTC as far as I can tell from personal experience...
You should mine for litecoins. Now that's actually practical and profitable on even an old GPU. :3
Yes, it's because your graphics card is crap... and also because it's nvidia, which is significantly worse than AMD for bitcoin mining.
This look into getting say a radeon 7770 7850 they are both pretty cheap with decent hash rates
I am a newbie miner. Wondering if the hash rate Im getting is what should be expected?
I have 3X Gigabyte AMD Radeon HD 7970 OC 3GB
Mobo: GIGABYTE GA-990FXA-UD3
1200W PSU
8GB RAM
AMD Athlon II X2 270 Regor 3.4 GHz
windows 7
I am running Bitminter pool for Bitcoin
1st GPU: 573 Mhps
2nd GPU: 574 Mhps
3rd GPU: 355 Mhps
Another question, why is the 3rd GPU going slower than the other 2?
