LTC Reaper 5870 not working

[tatsuchan]

Did anyone get reaper working for a 5870 card? I have 2 5850's going just fine, but cant get 5870 to run with the other two. Immediate crash. Tried running card on different computer by itself, still immediate crash. Using stock settings other than adding device id and proper pool id. Both on windows 7. Am I missing something? Card works perfect with bitcoin/phoenix miner.

Having same problem.  I think I may need most up-to-date drivers, but that sucks because the new drivers kill my hashrate for mining BTC.

With my 5870 and older drivers, I get "cannot build open.cl something something"

With my 6970's and older drivers, I get "reaper.exe closed unexpectedly" and it crashes immediately when it tries to compile the kernal.

Reaper is really pissing me off.  Can't get my 6850 working right either.  To top it off, my 850 watt power supply died on me while running reaper last night.  It was a shit power supply, but still, held out fine for 6 months mining bitcoin but couldn't do 2 days with reaper. So now I got 3 5850's laying around while LTC are going up in value every day

Try Worksize 128  

Also, LTC mining requires more power due to increased VMEM usage. You must have pushed the PSU to it's limits.  

So that is most likely the reason for your PSU failure

I played with worksize and aggression.  Touching those setting usually optimize.  I can't get the card to even start with reaper without a crash.

The difference between 300 memory and 800+ does take a toll.  I'm guessing my PSU was at it's limit already.  That's not to say that Reaper could REALLY use an update for efficiency.  I'm thinking we'll be seeing a lot of those types of questions in the next few months.
