New version: Version 2.3.0 - February 23, 2012

Thanks for the update mate, but this version doesn't compile a bitalign kernel for my cards (5850's), it's the non-bitalign kernel which is much slower (~320MH/s vs ~400MH/s).

Copying over the bin from the previous version and renaming it from "phatk120213Cypressbitalignv2w256long4" to "phatk120222Cypressv2w256l4" doesn't work also (HW failures).
Woah now there is nothing that should stop it compiling a bitalign kernel. It just stops CALLING it bitalign. You're not doing the SDK 2.6 dance are you?

Yeah, I just read the changelog carefully. Nope, no dance, jumping back to 2.2.7 immediately gets back to ~400MH/s (I always unpack each cgminer version to a fresh folder, no leftovers from prev vers). I'll try the other kernels to see how they go. Tongue

What does:
cgminer -n
report? And what kernel .bin file is being generated for you by default?

Unless you can say "Nope, no dance, I don't have SDK 2.6 installed" or "Nope, no dance, jumping back to a fresh install of 2.2.7 that compiles a fresh kernel immediately gets back to ~400MH/s" you are probably doing the dance.  Most people doing the dance don't know it.

ck, if you can give me a hint as to how to compile a 32-bit version on a 64-bit linux machine, I can provide cypress kernels for l4 along with l8 from SDK 2.1.

Cannot do. You can only make 32 bit kernels from running on 32 bit OS I'm afraid.

The cgminer window closes really fast on Windows, you really need to put an #ifdef win getch() at the end of execution, since piping the output doesn't work either Tongue

Anyway, by a screen grab, it shows Platform version: OpenCL 1.1 AMD-APP-SDK-v2.5 (793.1), with 1 platform device (GPU 0 ATI Radeon HD 5800 Series), and my settings for engine (970) and mem (150).

The default kernel is phatk120222Cypressv2w128l4.

Now that's a serious groaner since the phatk kernel is only trivially changed it should not perform any differently  Huh Try -v 2 -w 256 since you're grossly underclocking memory.

If you start it from a dos prompt window the window won't close...

V2w256 is what I always use to get the ~400MH/s, but it seems to hover around ~320MH/s now. Gonna let it run more time and see if the stats change.

I did start it from a dos prompt, but it creates a new (console) window and closes it after it's done. Piping the output like "cgminer -n > report.txt" doesn't work either. Windows really sucks on these small things :S

I now have one 5850 running cgminer 2.2.7 and another on 2.3.0, on the same engine/mem clocks. I'll be counting the accepted shares on the pool they are connected to and see if there is a significant difference. Cgminer 2.2.7 is reporting ~400MH/s and 2.3.0 is reporting ~320MH/s atm. At first glance, it seems they are submitting the same amount of shares (39 vs 40), so this could just be a "cosmetic" change in cgminer 2.3.0.  Grin

That, unfortunately, does not make sense... and this hashrate drop is more than a little disturbing since there is no real valid explanation for it.

edit: it's so big it's like one has an intensity set and the other is running dynamic.

Yeah, you're right, it was just wishful thinking... The one on 2.3.0 has a U:4.22 vs 2.2.7 with U:5.35. Both are running at I:9.

My 6770 runs waaaaaaaaaaaaaaaaay faster with the diablo kernel.

I was reliably getting around 185-190 Mhash/sec with poclbm and phatk.  Now it's reliably around 202 with diablo.  Really noice!

I did notice that suddenly my poclbm performance dropped from around 185 to like 165 with this new release.  But I'm not complaining because of the pleasant diablo surprise.

Hmm. my 6770 runs around 230 Nhash/sec with phatk at 1030/300 clocks. -v2 -w256

I haven't been able to reliably run my 6770 above 960.

Ok. @960/300 I have 220-225
cgminer 2.2.6

Edit:
Summary:
@960/300 = 220-225
@1000/300 = around 230

cgminer 2.2.6

That doesn't mean you can't try -k phatk -v 2 -w 256
Based on what tenzor says, 960/1030 * 230 means you should be able to get 214

edit: He changed that to 220-225?  * 960/103 is 205 which is not far off what you're getting... Try it anyway  Wink

Ok, my findings so far:
5850 on SDK 2.5

2.2.7 ~400MH/s with phatk120213

2.3.0 ~320MH/s with phatk120222
2.3.0 ~400MH/s with phatk120213 *but* lots of HW errors!

So it seems the hashrate drop is in the kernel changes?  Huh
