NiceHash QuickMiner 0.5.3.3 Stable release!

Dear NiceHash miners!

QuickMiner 0.5.3.3 Stable is released! Download and update it now.

If downloading the installer, make sure to select the appropriate version at the first step of installation.

Version 0.5.3.3 Stable is released. It brings the following changes:

FEATURE - Support for reporting mining statistics with key 's'
FEATURE - Support for AMD cards
FEATURE - Unlock LHR cards
FEATURE - Store autotune parameters
FEATURE - OCTune LHR manipulation
FEATURE - Implement Game Mode for AMD card (same level of support as NVIDIA cards)
BUGFIX - Fix crashes due to the presence of AMD processor with integrated GPU (and hardware not supported by Overdrive)
BUGFIX - Integrated GPU is now properly recognized but is disabled (appears as "stopped" in rig manager)
BUGFIX - Disable GPU with less than 5Gb of VRAM (GPU appears as "stopped" in rig manager)
BUGFIX - Fix issue where the AMD detection routine in QM was failing while loading hardware information on a rig with more than 5/6 GPUs. The routine can now support up to 16 GPU's
BUGFIX - Fix the issue with the 5xxx online profile crashing the driver on reset when the core voltage has been modified
BUGFIX - Fix a potential memory leak in OpenCL as all allocated memory buffers were not properly released when a new dag detected
BUGFIX - Correct memory leak due to cl_event
BUGFIX - Fix flow to avoid crashes on non-ampere GPUs
BUGFIX - Fix for incorrect speed reporting at startup
Cosmetic changes in excavator execution window:
AMD cards are displayed in the same way as the Nvidia ones
error messages related to the AMD detections appear only for machines having AMD cards
remove unnecessary debugging information
Remove unnecessary cl_event
Use a fixed delay time in latency hiding logic
Reorganize buffer declaration
Allow bypassing AMD device detection which seems to not work for some users
New icons
Connection related reports
Added age agreement checkbox
Removed hidden miner execution settings
More stable speed reports during runtime
A small improvement on Ethereum kernel
Bug fixes and small improvements

QuickMiner LHR Unlock FAQ

What is the percentage of LHR unlock?
It depends on your GPU. Expect the unlock to achieve around 74% of potential speed. We have noticed that different GPU performances can vary by more than 5% due to the silicon lottery.

Can all GPUs run at the same LHR settings?
No. Because of the silicon lottery, some GPUs might lock faster than others.

Can I manually modify LHR settings?
Yes. You can modify LHR settings via OCTune. Remember to set optimize the profile to Manual before. In the current release, only writing LHR settings is supported. Reading the LHR values from OCTune will be supported in next release.

Can I modify optimize profiles?
Yes. Read this article for more information. In the current release, some of the functionalities are missing and will be added in the next release.

What does LHR Unlock Ratio mean?
LHR Unlock ratio is a percentage of unlock. E.g. 72%. Expected values are from 60 to 80.

What does LHR Intensity mean?
LHR Intensity helps with the higher unlock ratio but can cause stability issues. Increasing intensity will allow higher hashrates. Lower intensity will increase the stability of the LHR Unlock. Expected values are from 30 to 50.

My GPU is locking frequently, what should I do?
Your GPU cannot run the LHR settings provided in our optimize profiles. Let us know what GPU you are using and what profile causes the issues. Then we suggest manually playing with LHR Unlock settings and setting overclocks via OCTune. Generally, LHR Unlock "70" and Intensity "34" should work on all GPUs.

The power consumption and core clock is fluctuating a lot, what is going on?
You probably used a classic overclocking method (setting delta values e.g. +500 memory). We recommend using alternative OC method via OCTune where you can lock the core clock. This will result stable core clock and power consumption.

QuickMiner AMD FAQ

Are optimize profiles supported?
Yes, for most of the modern models. Some GPU profiles are missing but will be added later. We are constantly updating the profiles.

How can I overclock AMD cards via OCTune?
Simply open OCTune via Windows tray menu > QuickMiner > OCTune and use AMD overclocking field to set core, memory, and voltage.

What AMD cards are supported?
All modern AMD GPUs with more than 5GB of VRAM are supported. We have tested this release with RX 400 series and newer.

Known Bugs:

Sometimes QuickMiner (Excavator) will recognize full hashrate GPU as LHR and the hashrate will drop to 70% of max hashrate. This might happen when a user is using the GPU for mining and gaming or some other GPU-intensive tasks at the same time.

To resolve this issue, please update to QuickMiner v0.5.3.4 RC where this bug is fixed. You can simply update to RC by opening the config file and changing the "bUpdateRCVersion" : false, flag to true then restarting QuickMiner.
