Topic: 5870 not hashing in new computer - Stream 2.1 installed - page 2. (Read 6246 times)
90 degrees is very close to the edge, I try to never let it go above 80 degrees by manually controlling the fan speed. If you're very close to the edge of where it will crash (20-30 MHz below) or you're over volting it should be even lower.
Tip: be careful with overclocking. I ran my 5770 at 975 MHz for a week (up from 850) and everything seemed to be fine. The GPU temperature never went above 90 degrees C, which I think is OK. (I'm a GPU n00b since I'm not a gamer.)
However, after shutting down my computer for a few hours yesterday, I'm now getting garbage pixels on the screen, and random "verification failed" errors when mining, at all clock speeds. Looks like I damaged the card.

I was trying to use DiabloMiner. Right now I'm trying again using windows, just to see if the hardware might be bad.
My speeds were slightly slower w/Diablo (peaked out ~343) but otherwise the same setup works fine for me.
I followed your setup with a single 5870, and I'm getting 13MH/s. o_O
aticonfig --odgc tells me clock is running at 850Mhz and GPU load is 99%. Am I missing something obvious? I'm not CPU mining.
Hmm... never experienced anything like that. You _sure_ you're not mining with the CPU? What output do you get if you just run:
./poclbm.py
without any flags?

Oh yeah I ment 320Mhashes. I overclocked the GPU to 900 and now im pulling in 340Mhashes. This is a surprisingly strong card.

320kh/s? Are you sure, seems low, unless you mean 320Mh/s?
Just installed my new shiny 2GB 5870 
. Got the latest drivers and everything. So far I love the card. A lot quieter than my GTX 285. Default I was running 290 khashes but with humbles extra paramaters i went up to 320 khashes!! awesome! This card is really quiet. The temps and fan are really low so Im assuming theres room for some overclocking

This card is really quiet. The temps and fan are really low so Im assuming theres room for some overclocking I run 4x5870s. Each is giving me about 355MH/S. They've all been overclocked to 900 and this is my setup. I'm running poclbm (I know the post says Diablo but that was then) with -w128, -v, and -f1 flags.

What i did was remove the "newer" SDK only, not the whole package, then install the .msi file of the SDK from the older package only.
Will do. Do you recommend completely removing the current version of the SDK before installing 2.2, or just installing 2.2 right over it? I'm planning on removing first, as that's generally how I've had to downgrade in the past, unless I should do it the other way.
having trouble finding the location to download a package with 2.2.
http://developer.amd.com/gpu/AMDAPPSDK/downloads/pages/AMDAPPSDKDownloadArchive.aspxThere you go, if you notice any difference please post how much is it.
Having trouble finding out how to downgrade from 2.3 to 2.2. I remember somebody saying that they had issues getting it to work correctly, but I can't find the posts where that was talked about and solved. Does anybody remember what I'm talking about, and can point me in the right direction?
Also, having trouble finding the location to download a package with 2.2 and not 2.3.

even my 5850 gets 310+Mhps (910MHz clock), SDK 2.3 slowed it down a bunch.
I've tried the 2.2 SDK as you advised, it gave me the same 300MH/s on my 5850 (900 core); back to 2.3 SDK. Thanks for the hint anyway . 
you should downgrade to SDK 2.2*, to get 300-340Mhps like Beremat
I'm getting 323MH/s on my 5870 with SDK 2.1, without messing with the clocking or voltage. I'm ranging between 285-295 Mhash/s.

*if running DiabloMiner 2.1 is even better/faster, i couldn't get poclbm to run on 2.1 though.
It has not gotten up that high since the first minute or so, so it was probably a bug in the GUI for poclbm. Or something I can't figure out.
I have a cheap MSI motherboard so I don't think it's my setup.

New drivers installed, 555.4Mhash/s. 
Nobody has pulled those kinds of speeds off of a 5870. Can you post more details about your setup?
You can check your Stream SDK version using GPU Caps Viewer.
Anyway, it turns out my problem was that CCC still thought I was running a 4850, so it set the core clock to 625Mhz. I reinstalled CCC, downgraded to Stream 2.2, and now I'm running between 300-340mhash/s.
