Overclocking needed for i7-5820k on MSI X99S Gaming 7 board and BIOS
Overclocking needed for i7-5820k on MSI X99S Gaming 7 board and BIOS
I have just finished a new build and have begun overclocking, achieving stable performance at 4.3Ghz - 1.25VCore (Noctua NH-D14 cooling) with a peak CPU temperature of 71°C under maximum CPU load (Aida64). I’m curious if anyone has tried using the MSI X99S Gaming 7 motherboard for overclocking their CPU and RAM before me?
At present, it seems relatively straightforward to configure, though there are numerous options to enable or disable features, with names varying from other BIOS versions. If you know any specifications for CPU settings within this BIOS that could help achieve a stable overclock, I would be extremely thankful.
My goal is to reach 4.5Ghz while keeping the VCore below 1.3 volts, and then gradually increase the Northbridge frequency as far as possible.
Here’s my current setup:
If anyone has any suggestions regarding overclocking the i7-5820k, DDR4 RAM, or the MSI Gaming 7 board, I would really appreciate it!
UPDATE:
I successfully achieved a stable overclock at 4.4Ghz:
CPU stress tested with Aida64 under full load, without throttling or automatic multiplier adjustments.
Temperature remains consistently around 76-78°C. I plan to conduct a longer test soon using various benchmark tools.
(Side note: What is the highest frequency someone has managed for this processor?)
I'm facing some issues checking the CPU and RAM speeds on my own setup, as they don't match the stock performance. I can share some information about overclocking this CPU and motherboard.
For overclocking voltage:
First, increasing the overclocking requires additional voltage. For the CPU, you might need to raise the VCC in addition to the VCore. The motherboard usually recommends 1.890mV. The RAM should have its SA voltage offset increased along with the RAM voltage. Both adjustments can be made on the motherboard if you set your preferences in the BIOS.

I managed to brick my BIOS after increasing the northbridge frequency past 3.6GHz. The BIOS stopped responding and I haven’t been able to determine a way to flash it again to reset it. Luckily, I have another BIOS profile that I can switch to via a switch on my motherboard. I’m not sure how to proceed with resetting the BIOS when it doesn’t post.
I understand this is a old thread and I'm a novice overclocker at best, but I was able to reset my cmos with a button the back of my msi x99s sli and it fixed my problem on the next boot,.I believe I had overclocked the the cache too high, or maybe there wasn't enough voltage. Anyways all I was getting was blue screen. I switched to the backup bios and did some research, I then shut it down switched back to bios A and hit a little but at the top of I/O panel on the backside of the computer. It was fixed and ready for some more abuse. Alternatviely, there's jumper to manually reset bios on the motherboard, or you can take out the battery, just make sure everything is unplugged. FYI, I had worries about compatibility after the reset. I.E. 980gtx graphics card and wireless Logitech keyboard k400, but everything was fine.

I had previously tried what you suggested, and unfortunately for me, profile A on my motherboard is just completely bricked. I tried the CMOS button, shorting the jumpers and removing the battery. I had learned that apparently clearing the CMOS on this particular motherboard only resets the main CPU frequency and voltages and not the Northbridge frequency which is what caused the problem. I have since read that no one has managed a stable overclock of the Northbridge frequency above 3.6Ghz. For anyone reading this post, DON'T PUSH THE NORTHBRIDGE PAST 3.6 - IT AIN'T WORTH IT! haha.
I'm unsure if it will function but have you experimented with a manual flash using a USB drive? Are you referring to the actual CPU clock speed, excluding turbo boost?
I'm facing similar issues with the same motherboard and CPU, and I'm struggling to match the expected CPU/ram performance. I have some insights on how to increase both the CPU and RAM speeds beyond their default settings. You can find more details here:

When it comes to overclocking the CPU, I usually raise the VCC in addition to the VCore. The motherboard typically recommends 1.890mV, while the RAM requires an adjustment of the SA voltage offset along with the RAM voltage. Both can be adjusted on the motherboard if you configure them in the BIOS. For more information, visit:
http://www.tweaktown.com/guides/6755/int...ndex3.html
Regarding RAM overclocking, I consistently set the BCLK to 100, which allows the maximum memory speed of 2666MHz. Going above this usually necessitates changing the bootstrap setting to 125MHz. This configuration is often linked to stability concerns, as it can also impact other components such as the hard drive. Personally, I haven't encountered any issues running at BCLK 100 with a 2666MHz RAM on CL14 when using additional voltage. However, this might also depend on the specific RAM model. The highest stable overclock without extra voltage for RAM is 2400CL15, and I tend to stick with the stock configuration at 2400/CL16 without any XMP settings.
For the uncore/northbridge, the maximum boost is limited to 35x on most boards except the ASUS OC socket, due to a voltage cap. You can push it higher with extra voltage, but it requires more power. The motherboard suggests 187mV, though you might be able to go lower. Overclocking the uncore is only necessary if you plan to use high-speed RAM or have a premium memory module. It enables the CPU to access RAM data directly, and at 3GHz the write speed is capped around 47,000. For more details, see:
www.madshrimps.be/articles/article/1000671/Haswell-E-Part2-Intel-i7-5820K-i7-5930K-Tested/7#axzz3Ulfxceid
The standard RAM of 2133/2400MHz doesn't exceed the cap, so maintaining these settings for uncore overclocking is unnecessary. For further insights, check:

I experienced stability and performance problems when pushing the uncore beyond its limits, which made me worry about needing to supply extra voltage—something I can't monitor. This capability is exclusive to ASUS motherboards.
If you brick your BIOS after excessive overclocking, I remember it would reset everything to defaults. Removing the battery should restore the settings, just like clearing the memory of new configurations. You might need to wait a bit longer before trying again.
In gaming, I haven't seen significant gains from overclocking, and I usually perform better with stock settings than with an overclocked one. If you want to compare your experience with and without overclocking, feel free to share your thoughts in the thread.
I hope this information helps and good luck with your overclocking project.
Thank you for your assistance. I realize it's still in the beginning stages of this chipset. I've chosen to keep the processor overclock at 4.3ghz with northbridge at 3.5, maintaining the voltage near 1.29. I'm planning to lower it further. I ran the standard 2666mhz xmp profile for RAM and left other settings as automatic. If you're keeping the CPU frequency steady while disabling all C-state features, what should you retain in terms of voltage? You mentioned "Override mode," but I'm not clear on the details of the 'offset' and 'override + offset' options.

I share the same motherboard and processor, but I'm facing some issues with the CPU/ram speed compared to their standard performance. Still, I can share some insights on overclocking this CPU and board.
Overclocking voltage
Initially, overclocking demands additional voltage. For the CPU, you might need to raise the VCC in addition to the VCore. The motherboard usually recommends 1.890mV. The RAM should have an increased SAA voltage offset along with the RAM voltage. Both adjustments can be made on the motherboard if you configure them in BIOS. For more details, you can check this guide:
http://www.tweaktown.com/guides/6755/int...ndex3.html
Overclocking the RAM
I consistently use a BCLK of 100, which sets the maximum memory speed to 2666MHz. Going above this requires changing the bootstrap to 125MHz in BIOS. This setting is often linked to stability issues and can also impact other components like hard drives. I personally haven't encountered problems running at BCLK 100 with a RAM speed of 2666MHz on CL14 using extra voltage, though this might also depend on the RAM itself. I use Crucial Ballistic Sport, and the highest stable overclock without extra voltage is 2400CL15. I tend to stick with the stock configuration at 2400/CL16 without XMP.
Overclocking the uncore/northbridge
The uncore has a limit of 35x on most boards except the ASUS OC socket, mainly due to a voltage cap that extra pins bypass. You can push it up to 35, but you'll need more voltage. The motherboard suggests 187mV, though you might be able to go lower. Overclocking the uncore is only relevant if you plan to use high-speed RAM or have a fast memory type. The uncore allows the CPU to access RAM data, and at 3GHz it caps write speeds around 47,000. For more information, see:
www.madshrimps.be/articles/article/1000671/Haswell-E-Part2-Intel-i7-5820K-i7-5930K-Tested/7#axzz3Ulfxceid
The standard RAM 2133/2400MHz doesn't exceed the cap, so keeping those settings makes further uncore overclocking unnecessary. The article linked provides some different RAM speeds and performance results:
www.legitreviews.com/crucial-ballistix-sport-ddr4-2400mhz-32gb-memory-kit-review_151873/4
Personally, I faced stability and performance challenges when overclocking the uncore, which made me concerned about needing to supply extra voltage that can't be monitored. This capability is exclusive to ASUS motherboards.
Bricked BIOS
I had my BIOS bricked after pushing memory overclocks too high; it wouldn't boot and would restart repeatedly with code 67. Removing the battery restored everything to defaults, suggesting you should try this if you're careful with timing.
Overclocking and gaming
In games, I haven't seen significant gains from overclocking, and I generally feel better with stock performance than with an overclock. If you want to compare gaming experiences with and without overclocking, feel free to share your thoughts.
Good luck with your overclocking efforts!

Similar issues with XMP settings that force BCLK to 125MHz...
I'm using a manual configuration at 3200/14-14-14-34 and will experiment with other options or detailed timings. Q-channel speed is around 56 MB/s read, 50 MB/s write, 65 MB/s copy, and a delay of 56-62ns. With the 3200/14-14-14-34 setting, BIOS defaults to MMO1.9; clearing the battery should reset it back to default. Try this approach for better results.
