I have one about the same. gets ~40 mh on the APU and ~70 on the discrete. It crashes half of the time when you stop mining.
Just a little curious, does it make unbearable noise when you run bitcoin on both?

Are you able to adjust voltage for the discrete?

A laptop with Llano APU and 400 shaders.
With additional gpu and 480 shader.

Will I be able to mine with all 880 shaders?

No guessing, I need to know for sure.

Also, I didn't claim mobility chips release *first*, but since it seems you're really scrutinizing every word for some reason, here is the quote you posted, you can even go back and read it

will be among the first

They came in after the low-end desktop variants and nearly a month before the 69xx cards.
http://www.notebookcheck.net/AMD-Radeon-HD-6550M.41143.0.html
I'm very sorry but now you're making yet another mistake.

Do you know what the HD 6550M is? It's a rebrand of the HD 5570. Codename is Redwood, UVD is 2.2.
It's from the HD 5xxx family, so it's no surprise that it was launched so fast.



Are you stalking my posts?
It's nothing personal, but I've just noticed that you are posting many, many errors.

I have probably become too autistic  for my own good.

It's also a good idea to clarify your position when shooting someone else's down.  Either counter with stats that invalidate the point, or you're also spreading misinformation.
Do I need to? Read what Jack actually said.

"Also, AMD and Nvidia account for nearly all of TSMC's business."
This is so blatantly wrong, it's like claiming the earth is flat.
If you don't understand where I'm coming from, Jack made many bullshit statements before, like claiming the HD6990 is a 5 gigaflop card. This one is really bad misinformation.
Or when he claimed Barts was VLIW4
Or like when he claimed that mobiles parts are the ones released first
All of that is pure misinformation, especially the first one, and just now he wanted us to believe AMD and nvidia are TSMC's only customers...  Huh



The only 'real' clients for 28nm high-k metal gate wafers are Nvidia and AMD
Okay so now you're backtracking, I'll accept that. Before, you claimed AMD and Nvidia accounted for all of TSMC's business, suddenly now you were only talking about the 28 nm processes all along.

Bad news, interview of TSMC CEO confirmed 28nm chips will be delayed because AMD/Nvidia have canceled their major orders for this year.
28nm chips will only account for some 1% of their revenues by end of Q4 this year
Here's where you went wrong. High end videocard chips are very low volume, and TSMC has many other customers, so a low number like 1% could even be natural. But you didn't know that.
So you erroneously assumed that 1% was "proof" that Nvida and AMD cancelled their orders. This was the big fallacy on your part all along.

You posted a link that stated "28nm chips will only account for some 1% of their revenues" then stated "AMD/Nvidia have canceled their major orders". A feather becomes a chicken.


I was saying that 1% could still mean a lot of wafers. The reason for this is that TSMC has a lot of other customers who utilize their older 55 and 65 nm processes.
Then you attempted to argue against this, by claiming that AMD and Nvidia were the only customers of TSMC anyway in order to give the misleading picture of that 1 percentage amounting to nothing. Which is blatantly wrong. They have many other customer, Which is EXACTLY the reason why that 1 percentage could still be a lot of wafers.



The 28nm delay is real and it's happening.
TSMC's projected 28 nm revenues going from 2.5% to 1% does not mean the world is going to end.

This is not proof that AMD has cancelled their orders.

Okay. You don't know what you're talking about. It's best to just step back instead of spreading more misinformation.

Your world may revolve around video cards, but the real world does not do that.

expected to account for 2-3% of its total wafer sales in the last quarter of the year.

However, it now seems like this figure was exaggerated, and that chip sales based on this node will hardly go over 1%.
Going from 2.5% to 1%.
How can you be sure that 1 lost percentage didn't belong to nvidia?
As I said, everybody already knows nvidia sucks at new manufacturing processes.

5830's have a TDP ~150W
No, that was the 5850.

5830 has higher clocked shaders and use more power. They should be around 180 watt if I recall correctly.

Where does it say this?  Huh


1% could still be a lot of wafers. Do you have any data of how many of their existing customers are still utilizing their 65 nm process for example?
It was never a big secret that high end videocards have always been low volume.


Quote from: TSMC
The delay of 28-nanometer is not due to their quality issue, actually we have regular tape out and it is unplanned. The July ramping is mainly because of softening economy for our customers, so customers delayed a tape out to us. So therefore, the 28-nanometer revenue contribution by the end of fourth quarter this year will be roughly above 1% of our total wafer revenue.
How can you be sure this has any relevance to AMD at all? Southern Islands taped out already back in February...

So, the 2.9GHz will do 65Mhash/s...

What about the 2.6GHz version?
The cpu speed is irrelevant. What you look at is how many shaders there are, and how fast the shaders run.

400 shaders at 600 mhz is the strongest Llano you can get.


Running all 4 cores. Getting 65MHash/s
Best to deactivate the cpu mining and only mine with the graphics shaders.
Overclocking the shaders from 600 Mhz should boost your hash rate far more than the cpus ever could achieve.


If they make a power-efficient
It's vliw5 at 32 nm soi. It's far more power efficient than any other graphics card in existence currently.

completely stable at 900 MHz... and is producing 103 Mh/s. Not impressive, but it all adds up doesn't it!!!! The card runs cool - this is at a steady 46.5˚C.
That's pretty nice. Good temperature for sure.

And I tend to agree that even smaller cards have their place in certain configurations. For example, if you don't have a monster PSU, yet have additional pci-e ports, the smaller cards can help you make sure you utilize what you can from your PSU. As long as the architecture is performance/watt efficient like a 5xxx or 6xxx series, there's really nothing to lose.

Maybe you have a GPU on the motherboard that Ufasoft is using without you noticing?

oh damn yeah you're right. i figured since it said cpu miner...

it was stealing from my 5870 and mixing it with cpu also
To truly test cpu, use these flags:
-g no -t 8

It will tell Ufasoft to use 8 threads, and to not use graphics cards.




Not efficient at all.
Agreed.

Bios editing. It's pretty safe to do when you have a bios switch.

My second favourite would be Ati Tray Tools, but it doesn't support multiple cards.

since AMD uses the same company (TSMC) that could mean delays.

Not necessarily so, what you fear is completely unfounded. Traditionally, ATI/AMD has always been better than nvidia at utilizing newer manufacturing processes.

HD 4770 was built on 40 nm. It was released in April 2009.
GT 240 was built on 40 nm. It was released in November 2009.
ATI was 7 months ahead.

HD 5870 was released September 2009.
Gtx 480 was released March 2010.
ATI was 6 months ahead.

HD 4870 was 55 nm, released June 2008.
Gtx 285 was 55 nm, released January 2009.
ATI was 7 months ahead.

Do you see a pattern? The two companies specializes in different competencies. It would be unwise to attribute some of nvidia's weaknesses to the ATI team.

AMD had a momentarily weakness when TSMC cancelled the 32 nm process. This incident screwed ATI over because their strength was taken from them and they were trapped on 40 nm.
But this time, it's back to business as usual.


Looked long and hard to find confirmation on whether anything would come out Q3/4 this year,
only to find potential problems with the manuf. process of 28nm chips.
The SI tapeout happened in February

Like I said, ATI tends to be more competent on newer processes, so nvidia's problems may not necessarily be ATI's problems.

I'm fairly certain they will. And if the PSU doesn't have enough pci-e power plugs, the graphics cards always have power plug converters.

Mobility radeon's (laptop) will be among the first
Mobility chips have traditionally always been slower to release. It goes like this:
Desktop cards first
Mobile cards second
Workstation cards last


Most sources incl. donanimhaber & chinese leaks confirm what m3sSh3aD posted, the powerful 79xx series GPUs will arrive Q1 2012 at the earliest.
That's not what m3sSh3aD meant. He's guessing that they will release the entire top to bottom range in Q3/Q4 (using slightly inferior manufacturing process, but available earlier).

That's exactly what happened with 6750 and 6770 cards :|

I know. But AMD was locked at the 40 nm process at that time.
Barts was 1120 shaders.
Turks was 480 shaders.
They needed something inbetween. Instead of redesigning a new 800 shader asic at 40 nm, they reused their current chip. Redesigning new chips at the same shader numbers would waste millions of dollars.


This time it's different, they are no longer locked at 40 nm, and you know that.
