Disabling ULPS may reduce GPU throttling on Kaby Lake G based HP Spectre x360 systems and more

[Redaktion]

In our HP Spectre x360 review, we found that GPU performance was very poor in games, where it often throttled down to 400 MHz, less than half of its rated clock speed. Thankfully, there is a solution that should prevent such throttling.

I'm going to assume ULPS does the same thing for Vega M as it does for the standalone GCN chips. Consequently, disabling it would prevent the Vega part of Kaby-G from actually shutting down

Configuring low-level hardware through windows seems like a really bad idea (as the case shows!)

So... did they say that they were going to fix this at all?

Just some advice to the person who owns this, it's possible to get the GPU to run at 1011MHz, which is it's actual boost clock. This is done by installing one of the older Intel DPTF drivers on HP's website.

intel dptf (windows 10 v1803) 8.3.10208.5644

I have this working on my system at the moment.

Thanks Bipartisan_Integral installing that DPTF worked!
