@djm34
with your tweak my hash rate is increasing in a few kh/s per gpu, approximately 3-5kh/s but unfortunately more RJ
w7 64bit 14.6

if you are using catalyst 14.6 or below (lol... ) please replace in lyra2RE.cl

#define SPH_ROTL32(x, n)   (((x) << (n)) | ((x) >> (32 - (n))))
#define SPH_ROTR32(x, n)   (((x) >> (n)) | ((x) << (32 - (n))))

#define SPH_ROTL64(x, n)   (((x) << (n)) | ((x) >> (64 - (n))))
#define SPH_ROTR64(x, n)   (((x) >> (n)) | ((x) << (64 - (n))))

by

#define SPH_ROTL32(x,n) rotate(x,(uint)n)
#define SPH_ROTR32(x,n) rotate(x,(uint)(32-n))
#define SPH_ROTL64(x,n) rotate(x,(ulong)n)
#define SPH_ROTR64(x,n) rotate(x,(ulong)(64-n))

That should increase the hashrate (actually it is the inverse on 14.9... no idea what they are doing with their compiler between each version)

report if you see some increase or decrease and with which driver version...

blake256, I mean

Here's the big test I promised.

AMD Sapphire R9 280X (Vapor-X dual fan) Windows 7 x64 2x 24" Display @1080p
Using: sgminer-v5-Lyra2RE-RC1-WIN32 (default Lyra2RE kernel)
PC Specs: Phenom II X6 1100t @4GHz, 16GB RAM (@1600MHz), Samsung EVO 500GB SSD (system), peripherals and network - all wired

AMD driver 13.12 - skipped for now. Please provide your experience.

AMD driver 14.4 WHQL best:

Test length: 3 reboots, a minimum of 30-minute-run after each
Memory 1500, Clock 1030, Powertune 20, Intensity 15
900+KHps 70°C (VRM 68°C/81°C) 1760RPM HW:0 TDP-VRM:85W
UV: 66°C (VRM 66°C/76°C) 1640RPM HW:0 TDP-VRM:56W
YouTube 1080p/60fps video plays fine with occasional stuttering.
Display count (1-2) did only make minor difference regarding hash rate.
Photoshop does not bug out the driver nor make it fail.
Cakewalk Sonar X3 - 80+ tracks, spec-intensive project loaded, played and worked great on low-latency. No visual glitches.
Minecraft is a bit choppy but playable and does not bug out the driver nor make it fail. 50+ FPS most of the time.
Stonehearth is unplayable. Don't Starve is good.
Launching Chrome (x64, 10 extensions) with 13 pages works flawlessly (scrypt-n fails at being smooth big time). Stays responsive and fluent while dragging between screens.
~~ Intensity 16-20 yields 910-940+KHps but with significantly more stuttering and occasional mouse and screen lag (no HW errors, though).

Conclusion: This driver is great overall, very stable, good performance.

AMD driver 14.6 RC2 best(?):

Test length: 3 reboots, ran until driver failed
Memory 1500, Clock 1030, Powertune 20, Intensity 15
865+KHps 69°C (VRM 71°C/80°C) 1760RPM HW:5 (test1) TDP-VRM:77-86W (fluctuating)
UV: 66°C (VRM ?°C/?°C) ?RPM HW:? TDP-VRM:xxx
YouTube 1080p/60fps video - could not conduct test.
Display count (1-2) - did not check difference.
Photoshop - did not conduct test.
Games - did not conduct test.
Launching Chrome - did not conduct test.
Cakewalk Sonar X3 - single track project's visuals made the driver fail.

Conclusion: Driver failed during all tests. Unstable.

AMD driver 14.7 RC1 best:

Test length: 3 reboots, a minimum of 30-minute-run after each
Memory 1500, Clock 1030, Powertune 20, Intensity 15
850+KHps 69°C (VRM 70°C/79°C) 1800RPM HW:0 TDP-VRM:76-86W (fluctuating)
UV: 69°C (VRM 69°C/77°C) 1600RPM HW:1 TDP-VRM:56-62W (fluctuating)
Whilst undervolted, driver did not tolerate intensity 16 and above on the longer run.
YouTube 1080p/60fps video plays fine with occasional stuttering.
Display count (1 vs. 2) made a 30+KHps difference regarding hash rate.
Photoshop does not bug out the driver nor make it fail.
Cakewalk Sonar X3 - 80+ tracks, spec-intensive project loaded, played and worked great on low-latency. No visual glitches.
Minecraft is very choppy nearly unplayable but does not bug out the driver nor make it fail. 25- FPS most of the time.
Stonehearth is unplayable. Don't Starve is decent.
Launching Chrome (x64, 10 extensions) with 13 pages works, stays responsive when dragging between screens.
~~ Intensity 16-20 yields 860-870+KHps but with significantly more stuttering and occasional mouse and screen lag (a few HW errors time to time).

Conclusion: This driver is an interesting one. The more I rebooted the system, the worse the hash rate got. It seems to be stable, though. Will investigate further.

AMD driver 14.9 skipped until further improvements:
I tried it before. Memory frequency, clock and voltage gets locked permanently.

Final conclusion and thoughts:

14.4 WHQL worked the best for me.
Not everyone has dedicated mining rigs. The purpose of my test is to see what level of usability my PC maintains when mining Vertcoin-Lyra2RE. I was aiming to achieve a balance between the highest hash rate and the best PC performance.
The results of this test may not apply to all AMD R9 280X cards and may vary on different systems. This should be taken as mere guidance only.
That is also the reason I was not using "xintensity 64" during the tests. Tested clock frequencies: 1000-1100MHz (with an increment of 10).
Clock frequency @1020, @1050, @1080 all worked well but changing the clock did not make big a difference.

One more thing. I really enjoyed this whole testing and I'm very happy with what I've seen. It is amazing that we will have an algo that doesn't render my computer useless and annoying, draws way less power, silent and fan-friendly.
The last question is: Will I turn on the radiator this winter?

(I didn't understood either... regarding swapping blake works in strange ways...)
I will send to James, a new version with a new version of blake in 1 round (don't expect any change in hashrate though...).

is the algo swapped?

~1100kh/s at 900MHz  (my card is throttling due to high temp... I need to disassemble it... but won't be possible before vtc launch)
What is your power consumption so we can compare with nvidia ?

VTC.HASHLINK.EU is also ready 

Will the list of p2pools that vertcoin.org links to (http://coin.cubeconnex.com/poollist/) either be updated to only show p2pools that run Lyra2RE, or somehow show they're ready for the fork?

Thx

We heard from the Vertcoin community and decided to add Vertcoin up for voting to be added to Bitspark! Support Vertcoin Here

New blog post:

One more thing is according to the plan, or even far beyond the plan:




 

Verters is ready.

Also we have updated our Getting Started Guide:

https://pool.verters.com/index.php?page=gettingstarted

We are (with the exception of poolz.net) the oldest VTC mining pool going (afaik), and will be with vertcoin right through the fork to Lyra2RE.

which pools or ready

Wallet updated perfectly, waiting for the fork to Lyra2RE

I think everything is going according to plan  

104 hour or 4.3 days to Lyre2RE Update from now  

Friends tell all your friends to update wallets  

share the news in your city, country or planet  

everything is working well! thanks

Yes, THANK YOU Vert team! Keep it up. 

+1 It works now

It works now. (Win 64 bit) Thanks!
