Well judging by the error CL etc etc Is SDK installed I would start there.
Make sure when you installed you didn't just get a driver but the full install with the SDK. What OS are you using as that has a lot of effect on how to get it to work.

ckolivas,
I know LTC is no more your favorite thing than Stratum is Luke-jr's. However a few of us are starting to see a lot of rejections with time-too-old issues. Do you have any insight what might be done to stop these? I mentioned it over at #ozcoin and Graet was kind enough to fire up an instance and he got "<@Graet> A:644 R:197 after 1.5 hours" so you can see its a ton of rejects I have seen 44-50% on my own miners with no other hardware errors etc.
Anything you can suggest?

I figured SDK too which is why I went to AMD and downloaded the latest SDK version (SDK 2.7) AND the latest CCC version (version 12. I am on Windows XP 32-bit

version 12. Does CGMiner support a version with sunglasses?

A: Because it messes up the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing on usenet and in e-mail?

Yes. https://dl.dropbox.com/u/7490029/cgm.jpgHere is what I am launching with, no .conf file stored, windows 7 64bit. 5770 card and Catalyst 12.7 cgminer.exe -o http://lc.ozco.in:9332/ -u username -p password --scrypt --shaders 800 --intensity 13 --worksize 256

Is this new? If so, can you pinpoint which version it started from? If not, is it unique to lc.ozco.in ?

Fairly recent yes. https://dl.dropbox.com/u/7490029/log2.txt Log file with debug turned on. I haven't tried another pool lately, will try that now. As for version I had been running bfgminer, all the way up to 2.8.1 was getting the error so switched back to cgminer then have tried cgminer 2.7.5.

Will be happy to look into that more but so far it has seemed to be occouring independant of what version I run of either . I tried your suggestion and jumped to another pool and I am at a:276 with only r:5 and those were all prevhash-stale. So it may be pool dependent, I even have I=18 right now and no issues with rejections.

What was the earliest version that did -scrypt? I just tried 2.6.5 and it does it with ozcoin too. ( log https://dl.dropbox.com/u/7490029/log2.6.5.txt )

(here: https://bitcointalk.org/index.php?topic=28402.msg1231316#msg1231316) I found that 2.6.4 is the "newest" version that doesn't seem to exhibit the same symptoms.

TY for finding that, the oldest copy I had on hand was 2.6.5 and the oldest windows version avail on his site is 2.6.6 so I had no way to test lower versions without a lot of digging.

for what its worth BFG miner 2.6.4 still gets the time-too-old with ozcoin. Thats the only 2.6.4 windows version I was able to find. UPDATE: Also 2.6.4 of cgminer does it. https://dl.dropbox.com/u/7490029/cgm2.6.4.jpg

In that case it might actually be the pool's fault setting a high rolltime and then rejecting the shares as late.

Thank you ckolivas, was afraid it may be something to do with the pool. I did find some other threads also stating that if time on the pool server was drifting too far it may be the cause too, hopefully Graet can uncover the issue cause I dont want to pool jump.

Scrypt mining is still broken in that it can not utilize high thread concurrencies (I need to use a thread concurrency of 24000 for my 7950s to mine effectively). The bug seems to be with the calculation for memory allocation. It can be easily duplicated by setting the thread concurrency above 8192, eg 12288. In reaper, any thread concurrency may be used as long as it is a multiple of 64 and produces a memory padding that fits within the card's memory space.
Using "set GPU_MAX_ALLOC_PERCENT=100" in Windows allows the program to run, but it doesn't hash at all and does not create a memory pad on the GPU.
I reported this several weeks ago and it still hasn't been addressed.

That's cause I have no idea what the problem is. Setting GPU_MAX_ALLOC_PERCENT does nothing on windows, only linux.
