ULTIMATE Mac Pro 5.1 configuration !!!!

2x3.46GHZ Xeon Processor

96GB RAM (6x 16GB 1333MHZ DDR3 sticks). This is the best combination possible because adding additional sticks would make the RAM operate slower.

Working Superdrive (CD+DVD burner)

Storage : 1x 2TB NVMe on a PCIe card + 1x 1TB 3.5" Hard drive (for data). This hard drive can be installed in the second superdrive slot so all 4 sata drive bays can be used to add a RAID0 4 drive array, ideal for video editing.

MacOS Sonoma installed on 2TB NVMe using opencore.

PIXLAS MOD : The PSU has been modified to add a second 8-pin power connector for the GPU, allowing more powerful GPUs to be installed in the machine.

GPU :
A NVIDIA Geforce GT630 2GB (flashed by macvidcards) is included, this is only intended for troubleshooting boot/opencore problems because this GPU will give you the original mac bootscreen. You will be disappointed by the performance of the computer with this GPU.

You NEED to add a powerful GPU (like a Vega 64 or a Radeon VII) to take advantage of the Pixlas mod and unleash the power of the machine : you will then have the most powerful mac pro 5.1 possible.

USB 3 PCIe card (4 ports).

Will be safely shipped in custom made box.

NOTES :
1) the wifi of this computer is not functional because the wifi card was removed. These cards are available online for around 20€. The 2 ethernet ports work fine.
2) The motherboard of this computer is a 4.1 , which was flashed to a 5.1. Performance and feature-wise, there are absolutely no differences between a "real" 5.1 and a 4.1 flashed to 5.1, other than the mention "early 2009" in the system report.
