mind sharing that strap, or at least give a hint at some values you changed?

Also I didn't push the gpus too far, so they're a bit loosened..I'll post my best results on windows later.

Here's my latest update on Linux --> 3x Sapphire Nitro+ RX 480 OC 8GB, Sapphire Nitro+ 2x RX 480 8GB, 1x MSI Armor 470 4G all Samsung
{ "gpu_temp": " 61 61 60 61 62 61", "gpu_fanspeed": " 40 60 40 23 33 21", "gpu_core": " 1165 1100 1145 1165 1165 1145 ", "gpu_memory": " 2120 2050 2120 2120 2050 2120 " }
GPU0 -100mV, GPU1 -100mV, GPU2 -125mV, GPU3 -100mV, GPU4 -100mV, GPU5 -125mV -> ATW consumption 816W
Here's what these are doing on windows --> Almost the same config but 1 Nitro+ OC was at 2120 not 2050(probably bad batch, so I lowered it to get it stable)

By my calculations. Else is fine.
EDIT: I wouldn't touch PMG timing
Thank you! I won't touch PMG, not sure what is its purpose anyway. Not very experienced at this stuff. I'll just play with RAS, CAS, MISC.... brick my card maybe...

I got my 2 Sapphire 470 Nitro+ 4GB with Samsung rock solid @ 29.5MH/s on eth.
This is on Linux box... Maybe win would be a bit faster.
I got 30+ but it's not that stable...

Can you post the strap you are using? I'm not having much luck getting my Sapphire 470 over 27Mh. That's running memory at 1900 with the 1500 strap. Using the 1375 strap gives me errors mining ZEC.
Here's the 1375 & 1500 straps from the stock BIOS:
Code:
333000000000000022CC1C008CCD593AC0570D13AA09B4070048C7007A0014207A8900A002000000140D272E7B252B15

I want to jump on editing the straps, so far i have a general idea of what each of the values mean and i'll use the cheatsheet at http://www.tweakers.fr/timings.html#tRP once i can get to edit them, but i'm not sure on how to get the info for my specific memory to know where is each of the memory timings.
Where should i start?
Thanx guys!
Best regards

Each card is different.
I got 2 identical GPUs with 8G samsung memory and 1342 stock core I believe Sapphire Nitro+ 480 OC is the right model.
One of them did 32.5 with Claymore at 1200/2225 and was stable without errors, the other crashes after a minute on 2100 clock... so test each card individually.
PP: As it is already said dagger-hashimoto performs better with loosened timings and higher memory clock. Don't expect miracles on clocks below 2000.

1150 / 1900mhz = 27.5mh (MSI 470 Armor 4GB)
Using Claymore in Windows, 16.11.5 drivers
I've noticed some odd behavior though... on my initial attempt I was able to gradually raise clocks on one card as high as ~2100mhz (I saw 29.5mh!), but it only seems to work if I raise the clocks while miner is already running and then pause/unpause, the initial miner / DAG loading does not seem stable with these timings at high clocks.
My other test card I seemingly had mining stable up to 2050mhz, only to find that it can't create the DAG at anything above 1965mhz without crashing the system
I've also noticed that the Samsung 4GB equipped cards doesn't seem to report any GPU memory errors in Hwinfo64, even when memory clocks are pushed high enough to cause errors / crashes in Claymore.

(just so you know, i'm not going to do this on a daily base.. :p)
Greetings!
Try it not stable for me, but after change it from 79 to 98 it got stable with same speed.

Maybe cause my card not good enough, or cause I still playing game with my pc.
would i be able to use these timings on my two asus rog strix oc rx470 hynix 4gb?
i have copied the 1500 timings to all the higher values and flashed that. if i try to OC the cards mem to 2000 using afterburner or wattman i cant seem to keep it stable. im running win 7 64bit.
