Try to use double threads this way:
"gpu_threads_conf" :
[
{ "mode" : "GPU", "worksize" : 8, "alpha" : 64, "beta" : 8, "index" : 0, "multi_hash": 224},
{ "mode" : "GPU", "worksize" : 8, "alpha" : 64, "beta" : 8, "index" : 0, "multi_hash": 224},
],
also try this config:
"gpu_threads_conf" :
[
{ "mode" : "GPU", "worksize" : 8, "alpha" : 64, "beta" : 8, "index" : 0, "multi_hash": 464},
{ "mode" : "GPU", "worksize" : 8, "alpha" : 64, "beta" : 8, "index" : 0, "multi_hash": 464},
],
or
"gpu_threads_conf" :
[
{ "mode" : "GPU", "worksize" : 8, "alpha" : 64, "beta" : 8, "index" : 0, "multi_hash": 448},
{ "mode" : "GPU", "worksize" : 8, "alpha" : 64, "beta" : 8, "index" : 0, "multi_hash": 448},
],
or
"gpu_threads_conf" :
[
{ "mode" : "GPU", "worksize" : 8, "alpha" : 64, "beta" : 8, "index" : 0, "multi_hash": 432},
{ "mode" : "GPU", "worksize" : 8, "alpha" : 64, "beta" : 8, "index" : 0, "multi_hash": 432},
],
Double thread 224 => 113 h/s same as 1 Thread Double thread 464 => PC Freez Double thread 448 => Driver crash Double thread 432 => Driver crash What's wrong ?  (same result on a VTX HD6950 and Gigabyte HD6950) i've already try 2 thread before asking on forum, same result as 1 thread ? Is it normal with this card ? |

I'm become crazy , i've 3 PC and ALL Crash, with 14.4 driver and 6950HD, i've allready post my config. Could u help me ? i'm very glad to fee you my hash  I must use this 14.4 driver with your miner ? i'm the only one who have problem with 6950. You must have Windows 8.1+. What config you're using? What amount of video memory your cards have? And what algo you what to mine? [/quote] Yes i'm on W8.1 My 6950 got 2Gb ram I'm mining V8 cryptonight the lastest fork ... So, it's hash a little now, my config parameters sucks. I'm testing on 33B6 and with this "jce_cn_gpu_miner64.exe Experimental boost ~2% for HD6000/7000" I've try a lot of parameters, but get not more than 100/113 h/s  It's crash when i up "multi_hash" value more than 240 That's the best result i can get with this config "gpu_threads_conf" : [ { "mode" : "GPU", "worksize" : 8, "alpha" : 64, "beta" : 8, "index" : 0, "multi_hash":240}, ], if i try Worksize 16/32 i can't UP than 240 thread. Did u have some values i can try ? because i've try a lot of combination but can't reach more hashrate, driver crash. i didn't understand whats that 2 values (alpha" : 64, "beta" : 8 ) ? The most curious it was, if i didn't OC my card like @910/1250 driver crash instantanetly when i start miner. in 800/1250 or 830/1250 driver crash. With all same values in config.txt . Wtf hell !!!   I've try on each card on different PC (don't have a rig) 3 different PC. Thx for helping. |

Online is the 0.33b-y* A lot less tested than a regular version, i hope there's no bugs out there * Fees lowered back to 0.9% on all algos, as I'm no longer 20% faster than the reference code * More hybrid, so should eat a bit more CPU * Bad shares on Heavy fixed, at least i had zero during my 5-hour test session * Light optim ~2% for HD7000 is backported to HD6000 * It was more stable on my rig, but i'm doubting of such observations That's the standalone .exe on Github, as for the previous b-x I'm become crazy , i've 3 PC and ALL Crash, with 14.4 driver and 6950HD, i've allready post my config. Could u help me ? i'm very glad to fee you my hash I must use this 14.4 driver with your miner ? i'm the only one who have problem with 6950. |

@Boss_One
Can you try XMR-stak on auto config? If it does not work it means that it is not miner problem but rig config (windows/drivers issue).
XMR Stak didn't work with 14.4 driver.... XMRig start hashing but freez or make driver crash and stop hashing. i've try to reinstall image with new w8.1 OS and try again with 14.4 Driver JCE Miner in auto mode or manual config ==> the driver crash. |

for HD6950, a user on Github advises to use worksize=32 and multi_hash=864, one one thread. Take a look at the HD6000 user topic here: https://github.com/jceminer/cn_gpu_miner/issues/26{ "mode" : "GPU", "worksize" : 32, "alpha" : 64, "beta" : 8, "index" : ...., "multi_hash":864 } also try with worksize=16 and 8 Hi JCE, I'm testing on my 3 - 6950 card with 0.33b4 /0.33b6 i've also try 8 and 16 worksize. But i didn't understand whats is alpha and beta values ?! 2 VTX 6950 2Gb 1 Gigabyte 6950 2Gb Also A Pitcairn GPU but didn't try yet. 2 os on W8.1 64 1 os on W10 x64 No card mine, and don't have error. I've never seen any hash start I post my config perhaps and i did it something wrong ?!

please do not drop support for old maps on your miner i have better results
r7 370 2gb - monero v7 srb 1.6.9 --495h / s
--monero v8 srb 1.6.9 --- 366h / s
jce 033b2 --- 422h / s
thank you very much for the miner for old video cards Thanks, and so long, if TeamRed stay far above my miner on RX/Vega, that's what will happen, i'll focus on older cards and CPUs, were i'm the best. It may sound strange i advertise for a competitor in my own topic, but those guys deserve it, they did a really great job. When I came on v7 six month ago, there were an obsolete Claymore 11, Cast which were fast only because it was the first to use correctly the Compute Mode introduced by the beta blockchain, and SRB with perf not that better than the legacy stak/xmrig. Here we're talking about +5% above SRB, which is already +2% mine. That's a real challenge. 0.33b4 under test, to be released soon. Heavy: i may gain some +0.1% by backporting the v8 optims, but i'm running out of ideas to get extra speed here. edit: i benched on my HD6950 and I get... +20% speed. Looks like the older is the card, the higher is my performance gap. It goes from +20% on HD6000 to -5% on Vega. The 0.33b4 will probably worth to be benched on Vega, still, i may not have +20% but even a +2% would fill in the gap with SRB. Hello i'm new with your Miner I've 3 - 6950 card so i'm very interesting by your miner ! On win10 x64 and 14.4 amd driver in auto mod i've NO hash. i also try on Win8.1 and 14.4 no hash too. I'vre try -c and manuel config "the gpu_thread_conf" Could you tell me what to write in the config file for get best HASH ? (i d'idnt fine explanation about parameters) Thx for your work, i hope u can help me |

Hi there I'm back with my old grand ma card AMD 6950   Ive try the lastest release since the fork V8 monero and i can't hash This old pre gcn card work on V7, it could hash on V8 ? ( i know it's old) but i've 3 card at work ... i've try kernel cmd line --kernel 1 or 2 and it didn't start hashing. The is a way to use specific kernel for this old card with a special command line ? Thx Since you're using an older card I'd suggest you try "kernel" : 2 together with "adl_type" : 2 because it's set by default "adl_type" : 1 which is better for newer cards. you can set it in config-normalv8.txt not in batch afaik, ReadMe is your friend! and take care not to forget a comma[,] or something +when editing config-normalv8.txt otherwise your miner won't work. I've try what you say but miner doesn't start anymore  Any idea ? i can't install adrenaline driver suggest, the card is not compatible. " Please use : Adrenalin 18.5.1, 18.5.2 or 18.6.1 drivers

oh too soon, it gives invalid results  flash bios 6950 to 6970 and use this config; 360 h/s xmr-stak drivers 14.4 // gpu: Cayman memory:1663 // compute units: 24 { "index" : 1, "intensity" : 874, "worksize" : 19, "affine_to_cpu" : false, "strided_index" : 1, "mem_chunk" : 2, "comp_mode" : true }, Who Did u get the good bios I've 2 VTX 6950 and 1 Gigabyte iv'e try To flash with 4 different 6979 bios at reboot card bip ! I've try this method https://www.techpowerup.com/articles/overclocking/vidcard/159Thx |

I've got 3x 6950, I've try kernel1, 2,3, 4 and i didn't get more than 210-220 h/s. @840/1250 intensity 25 worksize 8
Did u get more with those old cards? (stable)
I've try To flash 6950 To 6970 but the card bip and won't Boot.
2 VTX 6950
1 Gigabyte 6950
Someone flash successful wich bios is ok ?
Guy's could u share your config ?

Which miner did you use previously? Probably better optimized kernel or something to give better hashrate. SRB probably isn't optimized for older cards, maybe try with XMR-STAK?
I've try few miner after the fork, Claymore 9.7 give 350 H/s before the fork, XMR STAK didn't hash, Claymore 11.3 too ... I've also try xmrig amd, cast XMR. The only only one could hash is SRB. Do u know a miner could support my old card with better hash? Thx for your answer |

Hello I'm using 2 old RADEON 6950 on 2 different computer. It's the 1st miner could hash from the Monero V7 fork and I'm happy to discover this miner! I have a hashrate problem, I can't reach better than 145 H / s. Before the Fork I was doing 350 H / s with this card with other miner. I've tried the automatic intensity, and a lot of between 0 - 300 i've got the max with intensity 15 Is this card compatible with this miner ? Already it is stable and there is HASHRATE. Which is not the case with any other minor i've tried ... I hope you could help me with my 2 old radeon card. I'm Using Windows 8.1 X64 The last WHQL Driver for this card "15.7.1" There is some recommendation about the driver revision or other tips to Hash more with that card ? Thank you for your work @doktor83 I quoted myself Any idea about this card ? The blockchain driver did'nt work and the laster beta drivers didn't work too. So only the WHQL 15.7.1 driver works at low hasrate. Since the hard fork claymore doesn't support older card than 6xxx, i think u have a lot of old miner could be interested by your miner, i saw same problem on other forum as mine with this 6xxx card can't hash, SRB Miner is the only one could hash with my card. I hope you could help me. The blockchain and latest drivers won't work with this card because it is a pre-GCN card. Probably need custom timings in BIOS and overclock memory to get better hashrate. Ok and what about the hasrate 350 before hard fork ==> 145h/s after ? I know it's a very oldcard, but 700h/s on two card was prety good for those grandma i'm at the maximum OC AMD Override let me put : Gpu 800@840 Memory 1250@1350, Memory speed didn't impact the hashrate. It's seems the miner didn't take all the GPU "powerfull" |
