STM32F030K6T6 What I'm doing wrong?

Hi!

I'm trying to run this library on STM32F030K6T6, but I have a trouble with it.
All configs are correctly set, but the frequency is 4 times slower than that supposed to.

Screens:

Of course I added the TIM_NUM 17 to ARGB.c and hard-coded frequency, which should not effect on performance:
void ARGB_Init(void) { u32_t APBfq = 48000000; // Clock freq #ifdef WS2811S

ARGB.h:
`#define WS2812 ///< Family: {WS2811S, WS2811F, WS2812, SK6812}
// WS2811S — RGB, 400kHz;
// WS2811F — RGB, 800kHz;
// WS2812 — GRB, 800kHz;
// SK6812 — RGBW, 800kHz

#define NUM_PIXELS 100 ///< Pixel quantity

#define USE_GAMMA_CORRECTION 1 ///< Gamma-correction should fix red&green, try for yourself

#define TIM_NUM 17 ///< Timer number
#define TIM_CH TIM_CHANNEL_1 ///< Timer's PWM channel
#define DMA_HANDLE hdma_tim17_ch1_up ///< DMA Channel
#define DMA_SIZE_WORD ///< DMA Memory Data Width: {.._BYTE, .._HWORD, .._WORD}`
