Gateless Gate Sharp 1.3.8: 30Mh/s (Ethash) on RX 480!

Could you provide such a watchdog with your program ? Would be helpfull.

You mean, you want me to sell hardware? Never thought about that...

Edit: Now I think about it, I can make a USB/Ethernet watchdog on my own with Raspberry Pi or something like that.
All I need is an USB slave and a couple of relays. Interesting...

What I meant is, if possible, just ad the watchdog program to GGS package so that we can put it on a USB key and use it "out of the box".

That'd be pretty neat. The thing is, the cheap ones don't come with source codes:

Does anybody have the specifications of the WDG273 chip?

Sweet, very sweet...

Can this be exported to a custom strap, so we can flash it onto the card's bios?

Honestly, I don't know. You can reconstruct a custom strap for sure as there is enough information to cover the entire strap, but I don't know if that strap would work with other miners. You could always try...

I should also work on another command-line version...
Too much work, too little time!

Count me in soon. I still have an issue with the mem/timing/core tweaks. If it freezes the hardware, how and when can we be sure it worked ?

What I would do as a stress test is to run benchmarks with Repeats = 10 or even 20.
Statistically speaking, you need 100 trials for a 95% CI, but that would be too much stress on the hardware
and the results would be unfavorably skewed. If you are masochistic, you can turn on "Cool GPU down,"
which makes the test notoriously harder to pass.

On a more positive note, I just added extra parameters for memory timings to the upcoming version
for stability. We will see...

The "WDG273" does not exist, it's a relabeld chip to "hide" the real one ...  , these chips are normaly from ST like the STM32F042F6 with 32K Flash / 6K RAM or any other ARM Chip that fits the needs. What they need is an USB interface and some Flash/Ram - and it should be kinda cheap

Will memory timing mod work on old drivers like 15.12 or 16.9.2?

Please note that the current focus of the project is on AMD and this program has been tested mostly against AMD Radeon Software Adrenalin Edition 18.1.1. Other drivers may or may not work.

Prerequisites
The minimum requirements for the miner are as follows:

Graphics card(s) with the AMD GCN architecture and/or the NVIDIA Maxwell and Pascal architectures.
64-bit Windows operating system.
AMD Radeon Software Adrenalin Edition 18.1.1 or later for AMD cards.

Oh, it's a generic chip in disguise, then. I guess it's time to enlist an USB packet analyzer... Thanks a bunch!

Zawawa, forget about X17, Equihash etc.
Focus on bringing a fast Lyra2z miner, please. There's lots of speed to be unlocked for AMD hardware and a gap you could fill. The Linux-only TDXminer is already a lot faster than SGminer, and a guy called Kerney666 claimed to have achieved even higher hashrates with smart use of GCN ASM (as opposed to OpenCL).

Bring that to life and you've got a winner on your hands.

[zawawa]

I did realize it is too much to expect everybody to be familiar with all the wonderfully intricate details of GDDR5,
so I added a button that allows the user to "capture" memory timings real-time. It saves a lot of time!

Hmm... Very interesting. I just cannot wait to get back to GCN ASM.
Everything I did for GGS so far is a preparatory work, so to speak.
Don't worry, I will sweep 'em all very soon!

[skablast]

That's nice!
You are supposed to share it, you know ?
I saw your latest picture, it says version 1.3.6 ( 10 release behind !!!!!!!!!)
EHi, we are at 1.35 here so, 11 release behind.

And listen to the Dragonmike above you, Lira2z its interesting to say the least

[locbet]

Please support X17 Algo. Tool not good with vega 64

I still cannot install the 1.3.5 on my PC. The program is neither in add or remove programs, cannot find an uninstall file in the folder. How to proceed?
