bSendPackets Pattern

Is there a working Pattern for bSendPackets

those don't work for me:
DWORD SendPacketsArray = Mem.FindPatternArr(Engine.dwBase, Engine.dwSize, "xxxxxx", 6, 0x01, 0x8B, 0x01, 0x8B, 0x40, 0x10);
m_bSendPackets = Mem.Read<DWORD>(SendPacketsArray) - Engine.dwBase;

DWORD SendPacketsArray = Mem.FindPatternArr(Engine.dwBase, Engine.dwSize, "xxxxx", 5, 0xB3, 0x01, 0x8B, 0x01, 0x8B);
m_bSendPackets = Mem.Read<DWORD>(SendPacketsArray + 1) - Engine.dwBase;
