Kung Fury

I have actually tried another keyboard; it still happens. I'm going to grab a non-USB keyboard and see if that helps... I'm not quite at WS level, I have a professional enterprise build at my place of work for that. This is my home equivalent for research and development.

Great to hear some positivity! To be honest at this point I would be happy just getting things stable on stock, and then regarding overclocking I'm looking to go somewhere which is also stable. Because I'm using this for work in addition to fun, it needs to be practical. Previously I tried the "5-way" optimisation that comes as part of the mobo software, and found it friendly. However, given that the stock set-up seemed unstable I quickly went back to basics. Is the PSU up to the job given the set-up? I was wondering about that. Separately, I read that the X99-A can sometimes have (USB) power supply management issues.

Thanks for the prompt reply. I have tried the keyboard in all the USB ports; doesn't make a difference. I can try resetting the CMOS and see if that fixes 'overclocking failed' issues, but they are intermittent anyway.

First post, but you gotta start somewhere. Hoping you can help me with two specific issues. Overclocking failed No keyboard detected Back in January 2015 I purchased the following rig: CPU: Intel Core i7 5960X Extreme Unlocked, S 2011-3, Haswell-E, 8 Core, 3.0GHz, 3.5GHz Turbo, 40PCI-E Lane, 20MB Cache, Retail (Link) GPU: 2 x 4GB EVGA GTX 980 Superclocked ACX 2.0, 7010MHz GDDR5, GPU 1266MHz, Boost 1367MHz, 2048 Cores, 3x DP, 1x DVI-I, 1x HDMI (Link) RAM: 64GB (8x8GB) Corsair DDR4 Vengeance LPX Black PC4-19200 (2400), Non-ECC Unbuffered, CAS 14-16-16-31, XMP 2.0, 1.2V (Link) Storage: 250GB Samsung 840 EVO Basic SSD SATA III 6Gb/s 7mm Slim 3-core MEX Controller Read 540MB/s Write 520MB/s 512MB 97K IOPS (Link) 2TB Seagate ST2000DM001 Barracuda 7200.14 SATA 3 6GB/s 7200rpm 64MB Cache 8ms OEM NCQ (Link) Case: Silverstone SST-FT01S USB 3.0, Silver Fortress Tower ATX Mid Case w/o PSU (Link) Motherboard: OEM X99-A ASUS (Link) Monitor: 27" Asus PG278Q ROG Swift G-Sync 144Hz Gaming Monitor WHQD DisplayPort 2560x1440 350cd/m2 80M:1 1ms 2xUSB 3.0 Ports (Link) PSU: Only RM750W Modular Gold Silent PSU (Link) Cooling: Entry level water cooling block for CPU Apologies if some of the links aren't working now. They are 18 months old. The purchase was from a reputable company in the UK (which is where I'm based), who also did the build for me. In hindsight I wish I'd built it myself. This was a very high-end rig due to the requirements for high-end gaming but mainly the mathematical computational modelling work I do (neural networks, etc.). As far as I could manage this was a balanced machine that provided the best of both worlds. The provider did all the initial overclocking (non-GPU), including RAM. However, on first boot the machine went into overclocking failed and long story short I eventually turned all overclocking off. I later understood that with this particular Asus X99-A motherboard, overclocking the RAM with all slots occupied doesn't work very well. Despite this, I still struggle with two issues. Firstly, although the post is reasonably long probably due to the graphics cards and RAM, 1 in 4 times my post takes best part of a minute and eventually comes back with 'no keyboard detected'. Other times, I get 'overclocking failed' despite no overclocking. I have updated the bios to the latest version. I am keen to provide more information if necessary but curious to learn if anyone else has experienced related issues with this mobo and/or CPU set-up? Has anyone else maxed out the 8 RAM slots? I am keen to re-overclock this machine but I can barely get it 100% stable on factory settings. *Edit* I have tried the keyboard in different USB 2.0 and different 3.0 ports. No change. Overclocking failed issues are intermittent and around 25% of the time. Thanks for any help in advance.
