GPU comparison (Neoscrypt)

Alpha Wolf

It has ran 6 hours “the rig in question” and I will be checking it in a short while “its in my shop” I’m still in the house right now and just woke after only 4 hours of sleep.

I’ll post new info and screen shots if there is something new to report and I will also test it on a p2pool once I’ve seen how it has done solo mining.

I hope at least one of the 9 solved blocks my wallet shows were complete on that rig and then and only then will I be able to move forward with my testing for a pool.

Here are the results and also showing hardware errors, now to test a pool.

Sad part was that with the 13.12 bin & 14.9 driver I saw no improvement with my testing & hash rate but I’ll retest to make sure.

I’m trying to build a support section with ‘best answers’ to help everyone, could all new issues please be raised in ‘support’

Could we please keep this thread on topic with comparison details only. :)

I’m attempting to split threads out into ‘support section’, so if your thread was in here and it’s missing, please check back there.

After testing, there was varied amount of difference of speed between the the 13.xx and 14.xx drivers, using the 13.xx bins. Some were no change, others were 30% or more.

Using the 14.xx drivers with 14.xx bins appears to give across the board improvement in hash rate, but as proven so far they are 100% hw errors.

After doing a DDU clean of drivers a 2nd time then installing 13.12 with 13.12.bin I’m getting about the same

hash rate as I was with 14.9 driver and 14.9.bin with the exception of no HW errors, but as seen in the pic I

think the rejects are up a good bit more than they were before I started all this driver changing around and

playing with different bin files. The reason the kh/s doesn’t match is I down clocked my cards a little from the OC

I was using, once those clock are back to the OC they where in my other testing I’m almost 100% sure they will match.

Still using I 14 -w 32 -g 2 as it still seems to work best here for me and my setup so far.

I have 21 different 13.12 bin files of tested settings I will use later when I have more time with 14.9 driver and see

how that goes once its upgrade to.

Keep trying, you can get the reject rate WAY down… (I had 58 bin files)

Getting some rejects but no HW errors !

-w 128 -l 15 -g 1 -I 17

seems to be the best I can get as I cant overclock these 3 bad boys on linux

getting around 40khs on main card and slightly less on the two plugged into

pci-3 x1 slots.

Clocks on 1500/1080 now, no change to hashrate :)

Sapphire Vapor-X Tri-X R9 280X with Hynix memory doing 255kh/s - 265kh/s

Intensity 12, worksize 128, 2 GPU threads - clocks are 1150/1500.

Kernel is further modified; compiled on 14.9.

Edit on 11/04/2014:

Same card, doing 290kh/s or so

Intensity 16, worksize 64, 1 GPU thread - clocks are 1160/1500.

Kernel is even further modified; compiled on 14.9

Edit 2, same day:

It does just over 300kh/s on intensity 17.

Stock Clock-

3.7 KH/S -I 10 -w 32 (66 degrees)

OC (725 Main, 2050 Mem)

4.5 KH/s -I 10 -w 32 (69 Degrees - not pushing it hard, old card)

Hash falls as mem clock falls.

Had it laying around, cheers!

I OC’d each of my 750Ti cards on linux, and upped the TDP to 75W - flash 'em.

WOOOW I want it !!! :)

I know, the difference between Hynix and Elpida is night and day - my 290X, which I’m not certain, but if I guess from the hashrate, it’s Elpida, does maybe 310kh/s - 315kh/s.

The Elpida 280X, clocked at the same speeds as the Hynix one (1175/1500) gets 240kh/s. So, doing the math, a Hynix 290X would be…

310 + 310 * (290 - 240) / 240 or 375kh/s or so.

So what are you getting with your 750ti’s and which miner are you using?

Currently not using them at all, I have 5x750Ti around my room. But I was mining X11 - 2500kh/s or so with the ccminer off djm34’s github, 2800kh/s or so after I messed with it a little.
