Looking for someone with a XFX R9 280x Black Edition with Elpida memory. I am getting 289 and want to see if anyone is able to get more with the same card. If anyone has a modded BIOS for it that would be greatly appreciated! Thank you in advance!
Could you share your xfx bios?

Anyone here running R9 nano, what is the hashrate ?
4 x Nano Rig with -100mV undervolted ROMs
v12.2, smOS Linux
====
ZEC - Total Speed: 1493.538 H/s, Total Shares: 4992, Rejected: 15, Time: 08:58
ZEC: GPU0 375.775 H/s, GPU1 370.499 H/s, GPU2 372.478 H/s, GPU3 374.786 H/s
====
With stock ROMs, easily above 400 H/s

Today I had some issues with flypool. All of my rigs were like crazy - sudden hash drops, hangs, or no hangs but zero hash. I switched to other pool and the rigs are fine now.
Can somebody please explain what's the difference between H/s and Sol/s that nheqminer shows?
1 Sol/s = 2 H/s.
Bummer that you give a supposedly definitive answer, and it's exactly WRONG:
1 hash/sec yields ~2 Sols/sec (actually, 1.88 if the miner is implemented well). All the pools, blockchain explorers, etc. are reporting Sols/sec.

Bummer. 1.88 is a theoretical number that the miner will approach for a long period but not true.

Dave oh Dave.
zec will start rally soon, dont worry child 
You've got it right! Over 20% pump is going on. Hopefully won't follow a dump
There will be no dump, we will get price at 55/60usd by the end of next weekend
I remembered this comment so i researched it backwards and i am re-posting it
Let's see if by the end of the weekend you 'll get it exactly right..
Good "Guess" till now though
Second that
Can somebody please explain what's the difference between H/s and Sol/s that nheqminer shows?
Optiminer posted:
Generally H/s and Sol/s are used as the same. What you care about is Sol/s.
The mining in ZCash uses Equihash. On each Equihash iteration a number of solutions are found. This is a randomized process though. Sometimes 0 solutions are found, most of time 1, 2, 3 but it could also be more. On average about 1.877 solutions can be found per Equihash iteration. Some miners might though do some short cuts which improve iterations per seconds but do not find all solutions per iterations, hence finding less than 1.877 solutions per Equihash iteration.
Optiminer shows both Iterations/s and Solutions/s. The profit you get from mining is proportional to the Sol/s, therefore that's what you should care about. The reason why optiminer shows both is that Iterations/s is more stable than Sol/s (and you can compute the average Sol/s as I/s*1.877) . Sol/s has a high variance due to the randomness in the process.

Hello dude,
Allow me to congratulate you on your excellent miner and the hard work that this needs to maintain it, but I have a great doubt, I have 3 sapphire r9 280x dual-x cards with hynnix memory and I recently bought 1 card identical model exact all except The memory that is elpida, I would like to know, why if they only differ in the memory chips (they work with the same design parameters), the card that has elpida memory has a less speed than average 10,000 H/s?
Regards.

I have a similar issue like yours. I have a XFX R9 280x Black Edition that has Elpida memory and only gets 289H/s where a friend has the same setup but he has Hynix and he gets 310 out of it with lower clock settings. I am looking for someone who has a BIOS mod that might unlock that extra potential.

hi claymore
can you get more speedup for fiji ? i think hbm could get more speed, because Equihash performs better in large memory bandwidth.

HBM has great bandwidth, but the latency is high.

Hi, I have some problems with memory leak on Linux, after 24h of work RES memory size increases from ~125mb to 600+mb at it continues to grow.
I have 7970 cards and Claymore 12.1 under ubuntu 14.04 with latest fgrlx drivers.

Anyone has any info how much h/s r7 cards do? I found one r7 240 4gb with 45 w tdp for 50€. How god are those cards?
