I7 5820k Overclocking Help
May need to modify SA voltage (increase or decrease). X99 is quite particular about some settings, especially for cold boots. Warm boots are acceptable if that's the issue. The problem relates to memory training during POST. System works fine once running, only POST problems occur. Your Qcodes were Bd and bF. Have you tried memtest, other testing tools? I think it's the latest UEFI version. Are all manual voltages being used? Cache speed is also a factor?
Progress being made. Stress testing software should be run for a minimum of 2 hours to assess stability. OCCT is a suitable option.
I am currently using dual channel with a 16GB Corsair Vengeance Low Profile. This brings up two concerns. First, I’ve noticed a drop in performance since switching from an i5 4690k; after weeks of deliberation between the CPU and the i7 6700k, I’m seeing about a 10FPS decrease in most games except GTA V, which improved slightly. Could this be related to dual channel RAM? My second concern is whether returning my new parts and upgrading to an i7 6700k would be wise for my upcoming studies in computer science.
I would prefer to retain your system setup. Skylake will only offer roughly a 5% boost compared to your 5820k under identical clock speeds. Given your plans for future encoding, production, and other tasks, a higher core count would be more beneficial. Although not directly related, I also own a Skylake Z170 HTPC with an i5 6500, allowing me to discuss both platforms. Most reviews highlight significant improvements over Sandy Bridge, which is typically not overclocked. When running at the same speed, the difference becomes much smaller. It shouldn’t cause any noticeable drop in FPS. Since both models share a similar architecture, performance should remain comparable, possibly even slightly better with quad channel. The reason for dual-channel configuration remains unclear. What clock speeds do your 5820k and 4690k have?
when i placed my order for ram there were two very similar sets available. i had the 4x4 on my phone but mistakenly purchased the 2x8. when i received the 4690k i tested it at regular speeds: the i7 5280k, both stock configurations, 4.0gHz and 4.5gHz. there was no clear difference in performance. at the same clock speeds my cpu cache worked fine. however, ram didn’t accept overclocking. when i turned on xmp it would display a blank screen on the next boot after the asus logo with a flashing underscore in the upper left corner. it only ran at auto 2133mhz.
When discussing the lack of obvious speed improvement, or when measured in gameplay or benchmark results, X99 RAM at 2133 MHz might not show a clear gain. If this applies, it could be due to running dual channel only. The concern about 10 FPS is uncertain. Concerning the 2133 frequency, your CPU might not handle the 125 strap combined with overclocking well. I've observed similar issues and had to adapt accordingly for my 5820k. Reviews suggest that certain CPUs can only achieve higher core speeds or faster memory, but not both. Generally, reviews indicate a maximum CPU overclock of around 3.7Ghz with 3000 MHz RAM, or 4.5Ghz with 2600 MHz.
I'm having trouble getting my RAM to overclock properly. Since I'm not an overclocker, I don't know where to start. I've tried running at stock speeds and applying XMP, but the system still fails to boot. Could you share an overclock for your RAM, voltage settings, etc. I understand my RAM requires around 1.35 volts at 3000MHz for a successful OC.

I'm having trouble getting my RAM to overclock properly. I'm not really an overclocker, so I don't know where to start. I tried running at normal speeds and applied XMP settings, but the system still wouldn't boot. Could you share your RAM's specifications or voltage details? I remember it should work around 1.35 volts for a 3000Mhz boost, but that's probably not enough. The issue might be because your motherboard needs to overclock the memory controller itself. The maximum it can handle is 2400, so pushing 3000 is likely causing the problems. Also, using two different RAM kits at once seems to reduce my chances of success.
Are you testing the stock CPU speed once more? If this is happening and the XMP 3000 profile isn't performing reliably (as you've experienced with inconsistent boots), it's probably one of two issues. Either your IMC inside the CPU can't sustain that speed, or your SA voltage needs adjustment. What SA voltage value is set in your XMP profile? By default, it would be around 1.15v. In my case, stock runs at about .868v, but for the 3000 to function properly, I lowered it to roughly 1.02v. This setting is unusual because reducing it can sometimes resolve the problem. The relationship between speed and voltage isn't straightforward. XMP relies on averages, and not all CPUs handle higher voltages well. Also, as thor220 pointed out, exceeding 2133V typically triggers an overclock of the IMC. 2133 is the official memory speed limit for the CPU. Going beyond that will likely cause issues. Some CPUs cap at 2400V, while others can reach up to 3400V depending on the model. Additionally, when you increase CPU core overclocking, you might need to reduce RAM usage due to higher demand.
I’m unable to achieve the memory OC at any speed on the CPU. At first it worked when I booted, but now I suspect bios problems, with failed boots and related issues. Even in Windows it’s quite unstable. I posted online, but just in case my motherboard is an ASUS Rampage V Extreme, I had it refurbished from iBuypower and sold on Amazon. I installed updates BIOS 1, which caused terrible boot problems. I attempted to copy BIOS 2 to BIOS 1 to fix it, but I’m not sure what happened. Currently, whenever I try to boot through BIOS 1, I see the q code 00 and nothing else happens. BIOS 2 is also causing similar issues.
I have the chance to return this hardware and receive an i7 6700k. Until then, I’ll be limited to using my computer in the fall. Is this a better choice, or will performance remain the same if I replace the motherboard?
