I've noticed some big differences in current output from the TSP546 VRMs on a couple of my LV08s as seen in these next two lines of log info:
LV08_1: [TPS0: 1.193V, 22.500A, 48c] - [TPS1: 1.195V, 22.469A, 48c] - [TPS2: 1.193V, 17.531A, 45c]
LV08_5: [TPS0: 1.160V, 25.438A, 50c] - [TPS1: 1.158V, 18.844A, 49c] - [TPS2: 1.158V, 23.938A, 47c]
Both LV08s here are running at 525 MHz and hashing at 4.2 TH/s.
On LV08_1 (VOUT is actually set to 1.200v), notice TPS0 and TPS1 are around 22.5 Amps. However, TPS2 is only using 17.5 Amps.
On LV08_5, there is over
6.5 Amps difference between
TPS0 and TPS2!I believe power consumption can be reduced by at least 5 to 10 watts with individual control over the 3 VRMs thereby resulting in more efficient and cooler operation. However, I need some coding help to complete how the mouse click is handled in the code I have added below. Here is an image to show what it looks like.
<div class="field grid p-fluid">
<label htmlFor="coreVoltage" class="col-12 mb-2 md:col-2 md:mb-0">Core Voltage TPS * 3</label>
<div class="col-12 md:col-1">
<div class="field-checkbox">
<p-checkbox name="masterVoltage" formControlName="masterVoltage" inputId="masterVoltage"
[binary]="true"></p-checkbox>
<label for="masterVoltage">Master Lock</label>
</div>
</div>
<p-dropdown class="col-12 md:col-2" [options]="getCoreVoltage()" optionLabel="name"
optionValue="value" formControlName="TPS0voltage"></p-dropdown>
<div class="d-grid gap-2 mx-auto">
<button pButton (click)="set_TPS0_CoreVoltage()" class="btn btn-primary">TPS-0</button>
</div>
<p-dropdown class="col-12 md:col-2" [options]="getCoreVoltage()" optionLabel="name"
optionValue="value" formControlName="TPS1voltage"></p-dropdown>
<div class="d-grid gap-2 mx-auto">
<button pButton (click)="set_TPS1_CoreVoltage()" class="btn btn-primary">TPS-1</button>
</div>
<p-dropdown class="col-12 md:col-2" [options]="getCoreVoltage()" optionLabel="name"
optionValue="value" formControlName="TPS2voltage"></p-dropdown>
<div class="d-grid gap-2 mx-auto">
<button pButton (click)="set_TPS2_CoreVoltage()" class="btn btn-primary">TPS-2</button>
</div>
</div>
Code added to the "
edit.component.html" file to show the layout for individual control over the 3 VRMs on the LV08.
You can see the 3 functions that are activated corresponding to which TSP button was clicked (see image). These functions have been added to the "
edit.components.ts" file.
public set_TPS0_CoreVoltage()
{
}
public set_TPS1_CoreVoltage()
{
}
public set_TPS2_CoreVoltage()
{
}
However, these functions are empty for the moment as I have not worked out how to set up the procedure inside the these functions!
Any help would be appreciated...
