I’ve just purchased for a very good price a Lenovo Thinkcentre Tiny P3 fitted with a i7 14700T, Nvidia T400 GPU, 32Gb DDR5 5600 ram. Win 11Pro
My current system is a Lenovo Thinkcentre Tiny fitted with AMD Ryzen 5 Pro 5650GE/integrated graphics, 16Gb DDR4 5200 Ram. Win 10 Pro
I only use this PC for Roon and HQPlayer desktop and output to SOTM 200Ultra and HQplayer 5 NAA.
The dac is a Lampizator fitted with chipless DSD 512 engine and I can achieve Sinc Short/ASDM5EC-Fast 512 +fs/DSD512. Sounds good and no issues or glitches during playback.
I was hoping the new i7 14700T would enable me to explore higher modulators, i.e. ASDM5EC-Super 512 +fs and more demanding filters.
However the i7 14700T system cannot playback my existing Sinc Short/ASDM5EC-Fast 512 +fs/DSD512 settings without short glitches during playback.
This is a straight swap out. No changes to the network and the i7’s system’s ethernet is configured exactly the same as AMD ethernet.
I’ve played around with the CPU Multi core (off/greyed/ticked) and GPU Cuda (off/greyed/ticked) to no avail.
Does anyone know if I need to adjust the bios settings? Is the problem to do with the base clock speed of the i7 14700T, 1.3Ghz base speed and a boost up to 5.2Ghz.
Please check that you have Nvidia Studio Driver >= 580 installed from here:
I have i9-13900T and it can do DSD1024, without help of GPU using ASDM7EC-fast and default filters. So 14900T certainly shouldn’t have any issues, especially with that GPU to do same or more. The RAM I have is DDR5-6400 CL32 though, so faster than what you have, but still.
I recommend setting E-cores to “filter”. But this doesn’t really matter when the GPU offloading to the Nvidia GPU is working.
I recommend first checking that you can do the recommended defaults without issues:
1x = poly-sinc-gauss-long
Nx = poly-sinc-gauss-hires-lp
Modulator = ASDM7EC-fast
With sMS-200 as NAA, many have found that it helps setting “Buffer time” on “Outputs” tab to 10 ms.
Since it’s a T-family low power cpu, is there maybe some BIOS-setting to make it run in full speed? There might be some power saving profile on as default which throttles the CPU when trying to run a demanding HQP configuration.
Thank you for asking this question.
I have ensured high performance was set in the power section Win 11 but I haven’t looked at the bios settings yet as I’ve just been following Jussi’s advice to my original question.
I’ve made some headway.
I hadn’t updated the Nvidia drivers in my original assessment, now that I have it’s working as I had expected/hoped it would.
I don’t really know if turning Cuda on (grey) is really making a difference. In task manager there’s a little spike in the GPU window then basically stays at 0% but the music plays fine.
If I tick the Cuda box I get drop outs and again the GPU window shows a spike and then 0%.
I’m playing around with the filters and modulates to try and find the limits.
I like Sinc Ls and ASDM7EC-fast 512 +fs.
I’m relieved the i7 14700t is a performance improvement over the and 5650GE.
It should be set to checked in normal cases. Greyed means only convolution/large operations are offloaded. Checked means everything possible is offloaded. There’s some help displayed when you hover mouse over the setting.
I would recommend to check the Nvidia control panel for power mode settings for the GPU.
Just thought I’d post an update.
Without Cuda, I’m able to use ASDM7EC-super 512 +fs with Poly-Sinc-Gauss short. Sounds great.
Poly-Sinc-Medium or Long I get pauses every 5 seconds or so.
I’ve selected high performance/max power in the Nvidia control panel but if I select/tick Cuda I get constant pauses every 2 seconds.
It looks like Cuda doesn’t do anything useful in my use case, quite the opposite.
Perhaps Cuda would be useful if I were using convolution, but I’m not.
