Mining on a HD4000 and a 2500 (Yes, I hate the Enviroment )

[Evan]

Soooo I hate the environment, and am trying to squeeze every single M/hash I can out out of anything...

Right now I have my HD4000, slugging away at 15.1 mh/s

But I have an issue, my HD2500 works for a bit (30-40mins) at 4-5 mh/s and then quickly drops to kilo hash range?

Is this a cooling issue? or something to do with Programming? (I am using CG 10.2.5 command line on both)

I wasnt aware that hd4000 could mine at all  , last time i tried, it didnt want to start even. And for hd2500, must be a cooling issue, those things run hot whenever they do something

I think he's talking about integrated graphics on Ivy Bridge Intel CPU's

It is either a cooling issue or a shitty support for OpenCL issue.

 I know, that is what I tried. I tried last night after reading this, again. Seems that some kind of OpenCL is now implemented in new drivers and it indeed works. Slowly, but works. Altough I didnt have cooling issues since my computers are practicly in rooms with all windows oopen, and its 5C out there, I see temperatures that would worry me. Simply, its not the right tool for the job.

Yea but the Processor is running anyways, so why not let the HD run? I dont understand why the hd2500 died but the processor stays rock solid either

You have a CPU, why aren't you mining on on that too?

(hint: efficiency)

Like i said... F*** the environment... I am

The Core i7-3667U (and a Core i7-3770) is a 17w CPU I am getting 12mh/s + what ever i get on the HD4000 (15mh/s) this makes a 27mh/s machine.... We don't pay for power here so I am running VASTLY inefficient rigs...... its funny tho the i5-3470 nets ~20 mh/s solo so if I can squeeze the HD 2500 to give me anything more I might retire the 3667u sets and toss in some low end graphic cards to mine.

..... Stats...
    HD Graphics 2500 (6 execution units)
    HD Graphics 4000 (16 execution units)
 also yes I am stupid...

 I am about to buy a Xeon E5 2690 for my LGA2011 board to replace the other pc with a 3930K

OpenCL still does not work on the integrated GPU on Intel CPUs.

I hate to say this but why is CGminer working on it then? would you like screen shots?

Also CKo since i trust you I can let you log into one of the remote boxes to poke it.

I take it back, having looked at the intel websHite again, http://software.intel.com/en-us/vcsource/tools/opencl-sdk says "OpenCL 1.2
(OpenCL 1.2 on CPU mixed with OpenCL 1.1 on Intel® HD Graphics) (Version 2013 Beta)" which is new to me.

I think the drivers and/or HW capability were never created for the Sandy Bridge (2xxx models) generation of die-integrated graphics (so, HD 3000 & I think 2000), but the Ivy Bridge ones all have it, as will the rest in the future.

I knew the GPUs had the capability, it's just that Intel hadn't created an openCL SDK for them till very recently, and as you can see it's still listed as beta.

15MH at current difficulty equals 0.0021 BTC per day.

In a few months it will be 1/10th of that. Even if you dont care about the environment, how much time are you willing to spend to make a grand total of $5 worth of BTC extra - if that?

[vdragon]

I was trying all sorts of gpus some 3 months back, Intel HD besides them, and I remeber that I tried all kinds of stuff just to get it work, but I couldnt. So this support must be from few weeks back,which makes me happy since I manage one network that has over 100 of them

I was having the same problem.  It would run at 340Mhash for 20-30 mins and drop into the Khash range.  I could not figure it out.  I finally switched pools, mining software, and went to Stratum,  and it is mining better and more stable than it ever has.  Just my opinion, but it seems like the long polling was screwing it up.  I was also getting messages from the server that I was requesting work too soon.

What am  spending? I have the hardware. I dont pay for Electricity.   What is wrong?

The hardware isnt designed to run that, you will burn the CPU eventually especially it's a laptop.

You need much better cooling than the stock fan if it's a desktop.

They've been running non stop since the Nov 14th except for reboots, no failures... if someones does its got warranty. When i am done with them I will scrap them out or ebay them as office space used/abused machines.

[Carlton Banks]

Are you totally sure it wouldn't be more cost effective to sell the laptops for bitcoins? You could use the proceeds to put towards some hardware that will pay for itself...
