Gti14 96G: high memory latency in test

mike78

Hello!
I have bought Gti14 (96G 2TB) and some programs run slowly than my old computer (i5 11400). I peroformed passmark test and it show memory latency 86 while on my old PC it is 41. Is this normal? Maybe something I should switch somewhere, but I cannot figure out what exactly.
Thanks.

mike78 Hi there,please send us a picture of SN on the bottom of the PC.
1.Please repeatedly press delete key as soon as you turn on the PC, go to BIOS. Please send us a picture of the main page, we will check if you need to update the BIOS.
2.Update the driver.

mike78 Hi there,we’ve send you the files to update BIOS via private discussion.
Please check it.

Hello!
Thank you for BIOS files. I flashed, but memory latency is still 86. One program that I particularly need to run fast, (data processing via python), runs 1.5 times slower than my old computer with i5 11400 and slower SSD.
Also, memory test via passmark test shows all memory tests several times faster for gti 14 as compared to my old computer except memory latency, so I guessed that is the bottleneck.

mike78 Hi there,have you try to update the driver?
Please go to Intel website and download the auto-detect program.It will update some chipsets and video drivers automatically.

Hello! Thank you for suggestion, I updated even though the drivers available are only for Video, WIFI and NPU, and it doent change anything.

mike78 Hi there,sorry for the late reply.
1.This latency of 86 is normal. Your old machine uses DDR4, while the GTi14 uses DDR5. DDR4 inherently has lower latency, and a latency of 86 for DDR5 falls within the normal range.
2.Please refer to the tutorial:https://buildin.ai/8c4f9a06-5f9d-48ca-8cfe-bd9fd262f6d6
3.Please repeatedly press delete key as soon as your restart the PC, go to BIOS. Go to Boot option, enable fast boot, press F4 to save.

I added maximum powerscheme, to make it show I set DWORD value PlatformAoAcOverride=0 at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power, I enabled the scheme but it does not change anything. Enabled fast boot and it also did not change.
Also, when I used multi-CPU version of my python script, it also not that fast as it should be if I normalize by corresponding number of cores (i.e. it is faster, but only because it is 14-core vs 6-core on old computer, it should be 2.25 times faster or more while it is 1.5 times faster).
This python script loads many data files. If I use purely CPU-bound program, it is 15-30% faster in 1-CPU mode than old computer. So I guess it is related to memory operations - they are slower.

mike78 Hi there,
① Please go to BIOS and change the TDP to 65W , here is the tutorial https://buildin.ai/lizong/66f1daa8-7f9d-415d-a1f8-7d31454d8c8a
② Since this is for a specific script, you can attack the problem from the software side:

Use PyPy: If your script and its libraries are compatible, try running it on PyPy instead of the standard CPython interpreter. PyPy’s Just-In-Time (JIT) compiler can dramatically speed up CPU-bound tasks.

Profile Your Code: Use a profiler like cProfile to find the exact lines of code that are taking the most time. Is it the file loading? A specific calculation? This will tell you if the bottleneck is truly memory access or something else.

Optimize Data Structures: Can you use more efficient data types? For example, using Python arrays or NumPy arrays instead of lists for numerical data can provide a massive speedup and put less pressure on the memory subsystem.

Pre-compilation: Use Cython to compile performance-critical parts of your Python code into C extensions.
