X5675 Overclock Configuration
X5675 Overclock Configuration
I adjusted my X5675 to a 4.25ghz boost but still face an IRQL NOT LESS OR EQUAL error during startup. Since the core voltage is set above 1.33v and RAM runs at 1600mhz, it’s unlikely those are the causes. The issue might be elsewhere—could be related to drivers, firmware, or background processes. Anyone have ideas? Temperatures seem normal.
Well the board and cpu are both good for 6.4GT, I'm not sure what that is in ghz though. Should I maybe try dropping my multiplier and increasing the bclk? That would drop down the Qpi right? Because I already have the qpi multiplier set to 36x and the only slower option is slow mode... Anyways here's what I'm getting on HWinfo...
You've already boosted the voltage slightly without success—next steps might involve lowering the multiplier and boosting the clock frequency. Also, consider using Slow mode for QPI to evaluate stability.
I attempted to reduce the QPI but the multiplier is already at its minimum, so I’ll try just the slow mode and observe. Anyone have any effective configurations for achieving a 4.5 OC on the x56 CPUs? Especially those using gigabyte or award BIOS versions. I’m curious about how these settings differ and whether they reveal what’s wrong. This looks like a strong x5675 unit, and if it can’t even reach 1.35v, it might be a waste of time. EDIT: the slow mode runs at 84MHz, but the machine posts but is too sluggish for Windows—though it worked before, it wasn’t stable. I’m likely giving up on 4.25GHz because fixing the high QPI seems impossible.
I checked the X58 overclocking discussion for your updates. You're using a Gigabyte UD3R, X5675, and boosting the CPU to 4.5ghz. You've reached stable speeds around 4.7 GHz but saw diminishing returns afterward. A simple approach is to be extremely patient and tweak one setting at a time. Determine the maximum BCLK you can achieve with each component adjusted to a low multiplier, then repeat for memory and CPU multipliers. It took you over six hours to pinpoint the optimal settings—around 215 MHz with about 1.35V, memory boosted by roughly 8x, and a 21x CPU boost at similar voltage. You've experimented with other voltages before.
I just tested the settings TechYES shared on YouTube for a 4.5ghz OC, and everything functioned smoothly. Planning to run AIDA for a few hours, then weighing whether I should gamble my motherboard and CPU to push performance further. Likely yes—I’ll probably do it since soon I’ll have enough saved for a brand-new 9th gen Intel system (waiting on the hardware).
I use 1.45v with my X5670 chip (originally $14). I aim for about 1.58-1.6v and check if it reaches 5GHz. Since I'm running a custom loop, I have plenty of room to manage heat. Others say they've kept 1.66v daily for over four years, but I haven't verified that myself.
Find the link to that video. You’ve used 4GHz for a few years and are open to a faster daily connection.
You still need guidance for customizing the x5675? Disabling hyper threads can boost your GFLOPS in Intel Burn Test. Having six cores is more than sufficient for gaming, while a full 12 virtual cores aren't necessary. Ensure your uncore stays no more than twice the RAM frequency—typically around 1600 MHz. Based on my experience, keep RAM at 1600 and set uncore to 3200. Start with PQI at 6.4 and run Intel Burn Test, then increase to higher frequencies. Your system reaches about 22x200 (4.4 GHz) when optimized; turn off extra features like clock spectrum and Turbo Boost.
