5870 not hashing in new computer - Stream 2.1 installed

[theGECK]

Started using the -v -w128 flags, and increased by 20-30Mhash/s. Current speed, 313-320Mhash/s. Still running 2.3, no overclocking, no optimization. I'm a fan of seeing my graph on slush's pool jump 10x.

Haha yeah, I expected a big jump on the graph but not THAT big.

I'm fooling around with core speeds now, trying to see how far I can push this thing. I'm at 1000 core 275 mem right now, ~375mhash/sec. Hopefully it's stable.

Edit: Okay, 1000mhz failed and crashed poclbm, but 990 seems to be fine!

Changed to the Stream 2.2 release, and am seeing a 5-10Mhash/s average an increase in my average over using 2.3. Not hashing much faster, but the average is higher than it was before, and has less variation from one second to the next. Previously, it would bounce between 313-320, this is much more stable between 317-322. I'm looking for 2.1 though, and I'll update once I've done that as well.

Edit: Only able to find this page, is this ATI Stream? http://developer.amd.com/gpu/AMDAPPSDK/Pages/default.aspx#five The archive page on the download page for that link doesn't seem to be working, can anybody point me to a different place for 2.1?

Edit 2: My average was wrong, upon looking at previous data.

Get the download link of current and change the number to 2.1 =) Archive seems to be broken :\

That worked, thank you very much. I want to max out my hash rate today because I'm going to be away for awhile, and my computer can hash 100% of the time for 7 days, instead of me having to use it to do other things. Even a Mhash or two could make a difference over a long enough period of time.

Edit: Mhash/s has gone between 329-332 for the last 2 minutes, with occasional drops below that. Much faster.

Necro thread!

So, I moved my 5870 to a new computer, and the poclbm GUI says that I don't have any OpenCL devices on my computer. GPU caps viewer detects the stream 2.1 install I have, and says that I have stream 2.1. I'm not sure what to do at this point, since it worked perfectly on the last computer.

Do you have SP3 installed if this is Windows XP ?
Do you have at least one display or dummy plugged in each card ?

[theGECK]

XP Pro SP3, fully updated.

Two monitors plugged into one card. Same setup as my previous computer, and even plugged into same locations on the card.

[theGECK]

Bump, mainly because I can't figure anything out here, and I've missed out on a day of mining.

[theGECK]

Is there a way for me to move this to the Technical support area, or should I just create a new thread there?

How does one get a "dummy plug" for a displays?  I have 2 5870s in a windows XP machine, but sadly it won't probably enable the secondary card unless a monitor is attached on startup.  I'd rather not have to attach a monitor when I turn it on, how can I get around this?

Putting resistors in the vga/dvi adapter or directly into the vga card in order to simulate a monitor. Google dummy plug and check the first link.

Alright guys, I'm getting a lot of conflicting info here. I'm going to be setting up a dual 5870 rig soon and I'd like to know for sure what SDK to use in order to get maximum hashing performance out of it. Which is truly best SDK 2.2, 2.3, 2.2 or does it even matter? I think the latest CCC drivers use 2.3 so will it be worth it to use 10.x CCC drivers to use SDK 2.1?

I'm going to be using Windows 7 Ultimate 64 bit as my OS.
