Overclocking Startup issue
Overclocking Startup issue
Hi there.
I'm experiencing a problem with my overclock during startup. I'm using an Intel i5 6600K on an MSI Z170A M3, with 16GB G.Skill TridentZ DDR4 and a GeForce GTX 970. My CPU is set to 4.3GHz and it runs without issues normally. However, when starting up, my system restarts three or four times before it even reaches POST. It powers on, fans and lights activate, then it restarts and tries again several times before finally booting. I'm not sure what's causing this or how to fix it. When the system isn't overclocked, it starts up perfectly, so the issue must be related to my overclock settings.
Modified BIOS Settings are...
CPU Ratio-43 (4300MHz)
CPU Ratio Mode-Fixed
Ring Ratio-Auto
EIST - Disabled
Intel Turbo Boost - Disabled
DRAM XMP Profile - Enabled
CPU Core Voltage - 1.320
DRAM Voltagge - 1.350
(All other voltage settings on AUTO)
Intel C-State- Disabled
Long Duration Power Limit - 255
Short Duration Power Limit - 255
CPU Current Limit - 256
All other settings are at the default setting
Anyone have any suggestions?
Thanks ahead of time for your help.
I reviewed some documentation for this CPU. I recently assembled a new machine (my previous one used a Core 2 Quad Extreme, and I’ve seen a lot of changes over time, but I had overclocked my old PC before and haven’t faced this problem yet.) My RAM is DDR4 3200. When the XMP profile is enabled, it runs at 3200MHz in the BIOS; otherwise, it drops to 2133MHz.
haha bro u and i are sorta in the same boat.. except your boat has bells and whistles.
I’ve had a Q9300 for about seven years now.
So I think you should do more research and check with other users about the exact hardware.
I assume you’re more than just the basics since you’ve worked with an extreme CPU, so I won’t waste time on minor stuff.
what i did with my...
I reset the DRAM voltage to auto. The system works perfectly even when it isn't overclocked. Using MSI's game boost setting, which automatically overclocks to 4.1GHz, also functions without issues. My BIOS settings were based on MSI's game boost configuration, including the voltage adjustments I made to accommodate higher clock speeds.
Ryan_117 shared his observations about adjusting DRAM voltage and BIOS settings. He noted that setting the voltage back to auto works well even when the system isn't overclocked, and using MSI's game boost (which auto-overclocks to 4.1GHz) also functions properly. He mentioned relying on MSI's predefined configurations for voltage and other parameters, though he increased them slightly because he was pushing the clock higher. He also shared his experience with CPU-Z regarding XMP settings, suggesting to follow manufacturer guidelines unless you're following specific specs.
Currently, my RAM is using the pre-set XMP profile for my motherboard. I only modified the DRAM voltage because I based my configurations on MSI's "Game Boost" settings, which increased the voltage. After that, I switched back to auto voltage with the XMP profile, but the problem persists during startup. I haven't changed Bus Frequency, RAM frequency, or CPU Base Clock manually. I only adjusted the CPU Ratio to 43 (4.3GHz) and set the CPU Core Voltage to match the current speed.
Ryan_117 is using a predefined XMP profile on their motherboard, adjusting settings based on MSI's "Game Boost" options. They've switched back to auto voltage with XMP but still face startup issues. No changes made to RAM speed, bus frequency, or CPU base clock. CPU ratio set to 43 (4.3GHz) and core voltage adjusted accordingly.

haha bro u and i are kind of in the same situation... except your setup has more features.

So I think you should do more research and check out other users' setups to see what others are using.
I believe you're more experienced than just basic knowledge since you've worked with an Extreme CPU, so I won't waste time on minor adjustments.
What I did with my non-K overclock might differ from what you should do with a 'K' chip.
I only touched a few components and stayed within the DRAM frequency limits. (2700mhz max)
Bus speed went from 100 to 167mhz
RAM multiplier was reduced to 16x
Vcore was increased... I set it to 1.35, then lowered it to 1.30, adjusting every five hours during small tests and regular gaming to ensure I wasn't undervolting.
Now I don’t know much about your 'K' chip, so I can’t give you specific advice. I’m sure you can find reference samples to help you understand what changes to make.
But if I had to suggest something... it might be feasible to raise the core multiplier and lower the bus speed if you try that and observe the results. However, if you proceed like this, you’ll likely need to overclock your RAM too. All this seems really challenging lol.
And honestly, this is significantly easier than what I had to do with the Q9300. But it’s possible I might have hit a breakthrough with an i5 6400—since I haven’t encountered any issues during the overclock process.
