Can Maxsun Intel Arc B580 work on Intel DZ77BH-55K (i7-3770)? White screen + BIOS issues
Hello everyone!
I have Intel DZ77BH-55K motherboard (Z77 chipset, AMI BIOS 63-0100-000001-00101111-101111) with Intel Core i7-3770 (4C/8T, Ivy Bridge), 16GB DDR3 Corsair CML16GX3M4A1600C9 (4x4GB, 1333MHz actual), XPG 650W PSU.
Currently working: NVIDIA GTX 560 (PCIe 1.0 x16 @ 2.5GT/s PCIe 2.0 speeds)
Want to upgrade to: Maxsun Intel Arc B580 12GB (PCIe 4.0 x8 card)
What happened during first install attempt:
1. DDU NVIDIA drivers → clean Windows 10 install on Kingston SA400 SSD 2. Installed Arc B580 → **IMMEDIATE white screen with colored dots** (no signal) 3. BIOS wouldn't POST (blank screen) → **CMOS Reset needed** 4. After reset: "Bootmgr missing" → **restored EFI UEFI bootloader manually** 5. Now Windows 10 + GTX 560 works fine (YouTube stable)
Questions:
-
Will Arc B580 work on Z77 chipset? (PCIe 3.0 8GT/s support in BIOS)
-
What PCIe settings should I enable in BIOS before swapping? (Gen3 forced?)
-
White screen + dots = power issue (XPG 650W enough for 190W card?) OR driver issue?
-
BIOS flash needed? Latest version shows 0057 available, flashing 0100 failed before
-
Intel Arc drivers first or install card → then drivers?
Current BIOS Settings (working):
✅ UEFI Boot: Enabled (EFI partition restored) ✅ Boot #1: Kingston SA400 SSD ✅ Fast Boot: Disabled ✅ PCIe Link: 8.0 GT/s (PCIe 3.0) ✅ CSM: Disabled
Full CPU-Z report attached
Has anyone gotten Intel Arc B580 working on Z77 chipset? Or is this PCIe compatibility issue?
**Thanks!**
