Maximus II Formula isn't able to exceed the recommended speed limits.
Hello, I recently constructed my second overclocking rig and frequently encounter the "Overclock Failure" warning from the Asus motherboard. Although I have experience with Gigabyte boards, I’m new to ASUS and this has been confusing for me.
CPU: Intel Xeon 3.33GHz X5470 LGA 771 to 775 mod (I’ve updated the BIOS microcode)
RAM: 8GB Patriot 4x2GB 800MHz DDR2
MOBO: Asus Maximus 2 Formula with the latest BIOS update and microcode modification
CPU Cooler: BE QUIET Dark Rock 3
PSU: Cougar CMX 850W V3
CPU Voltage: 1.3-1.4V – nothing seems to work
CPU PLL: 1.55-1.60V
DRAM Voltage: 1.9-2.10V (NB: 1.4V)
FSB: 1.35-1.4V
SB stock or +0.5-1.0 increase
Despite trying voltages within this range, my PC still fails to pass the BIOS tests. I also faced issues with a Core 2 Quad Q6600, which only reached 3.2GHz regardless of voltage settings, and I experimented with CPU GTL, NB-CPU-DRAM skew timings, etc., but nothing worked. Anyone have any advice?
i've tested 3.8ghz but it doesn't need any voltage changes. my aim is to hit 4.2, and i've faced the same problems with a c2q q6600 on the same motherboard before the xeon upgrade. it only reached 3ghz and then stopped responding no matter what voltages were used.
it's an 80 plus bronze certified unit and it might hit nearly 80 plus silver standards. initially i used a corsair 80 plus 550w psu but later switched to an 850w from the main rig and the problem persisted.
Adjusted the issue by modifying the ram timings (6-6-6-18-24) since 2.3v wasn't sufficient (this was a bit odd) to maintain the FSB-dram ratio at 1:1 on 800MHz
