I purchased an X99 Extreme 4/3.1 mobo yesterday. I added my 5820K chip, which was in another mobo and overclocks fine, and 96 GB of (4x16 and 4x8 G.Skill 2133 MHz) RAM. Couldn't get it to post, but played around with the RAM and found 1 stick was likely faulty. Removed this, and PC boots just fine, is stable and everything works normally. All RAM channels work - it's in quad-channel mode. However, go to apply any overclock, no matter how small, and PC will boot but either freezes or BSOD in under a minute of windows starting. Same with the auto-overclock on the board. Happens if I just try and go to from 3.3MHz to 3.4 MHz. Have modified Vcore up to 1.3V, increased RAM voltage a little, decreases RAM speed - all sorts of combinations of things. Everything I've tried gives the same issue - perfectly stable at default settings, absolutely unstable with anything else. I'm on the latest BIOS version (3.10). Any ideas? My G.Skill 16 GB sticks aren't listed in the supported memory, but they seem to work fine under normal conditions. |

What is the full model number of your different types of G.SKILL memory? Mixing different models, or varying capacities of the same model, can cause problems. Depending where and when you bought your memory, it is possible they have different memory chips.There can be differences between memory option settings for memory meant for X99 and the 100 series chipset boards (Z170, etc.) You are using the latest UEFI version, is that 3.00 or 3.10? Assuming either of those two UEFI versions, you are using the Broadwell-E compatible UEFI update with your Haswell-E processor. What version of the Intel Management Engine software are you using? It sounds like you don't have the appropriate IME software update for the UEFI version you are using. We have no idea what version of Windows you are using, but it seems that there is only one version for all versions of Windows. Download and install the Intel Management Engine driver ver:11.0.4.1186 from here: http://www.asrock.com/mb/Intel/X99%20Extreme43.1/?cat=Download&os=Win1064" rel="nofollow - http://www.asrock.com/mb/Intel/X99%20Extreme43.1/?cat=Download&os=Win1064 Your symptoms of an OC not working, given your hardware and UEFI/BIOS configuration, most likely will be caused by not updating the IME software. Intel finally released it very recently. Some X99 users are learning this the hard way. The same thing happened with X79 systems, and the Sandy to Ivy Bridge compatibility update for Intel 6 series chipset boards. Do not leave the VCore at 1.3V, you should not need it, and it is rather high for your processor. Your memory compatibility is not causing the inability to OC. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

Thanks for the quick reply. Will check what IME version I'm on as soon as I get home and report back. Maybe something to do with whatever I had installed with the MSI X99 board I previously had (which OC'd fine with this exact setup, but died due to an unrelated issue) On BIOS 3.10. Had exact same issue with stock BIOS. OS is WIN 10/Ubuntu 16.04 dual boot (haven't checked how Ubuntu is behaving yet). |

Unbuntu is fine, but Win 10 isn't even with the updated EMI installed. Suspect it's something to do with not doing a clean install of Windows when I swapped the mobo. Problem persists. Best approach is to do a clean Win 10 install? |

A clean install is always advisable, especially if you are having issues. At the very least a fresh install allows you to rule out the OS as a potential cause. -------------

You have confused Windows 10 registry entries and who knows what else, given the differences between those two mother boards, both in hardware and software. Add to that the Broadwell-E compatible UEFI/BIOS, that contains a different IME firmware (not the IME software) that is part of the UEFI file, and you have a mess I would not trust. Of course, this is the first time we can really try using the Broadwell-E compatible UEFI, with the updated Intel IME software, while using a Haswell-E processor. I also use an i7-5820K in an ASRock X99 board, so will test that all myself. I just returned from the Computex show in Taipei, so have not yet had a chance to do it. I should have time later today...  ------------- http://valid.x86.fr/48rujh" rel="nofollow">

There is nothing wrong with your windows. I've been on bios 3.00 since i bought this motherboard and it has worked flawlessly. Last night i tried the 3.10 and it's highly unstable if you try to overclock. I can't get my system to boot if i touch anything above stock. It freezes either immediatly at post or it freezes when it reaches the point where it loads USB a second before login screen. I went back to 3.00 and OC @ 4.2 works like a charm and 100% stable. There is definatly and issue with 3.10. |

Windows reset fixed 90% of the issues. Set the auto-OC to 4.2 MHz and got a BSOD only under gaming load. Can boot fine and run without crashing provided it's not pushed. Could be either the rubbish 3.1 BIOS (as stated above), or the auto-OC settings aren't very good. Will try downgrading to 3.0 (or maybe test the beta 3.03). If this doesn't help, will start tweaking the voltages. Chip was stable at 4.2 MHz before, and seems a good overclocker. |

Well, it seems we have some differences of opinions... I can't comment on the 3.10 UEFI, since I don't have your board and don't have a version equivalent to your board's 3.10. I do know that with my X99 Extreme6/3.1 board, with the Broadwell-E compatible UEFI (3.00) installed (IME firmware version is 9.1.30.1008) and the new IME software components installed (version 11.0.4.1186), I have no problems with over clocking my i7-5820K. Raggz, it seems you are saying you could OC your X99 Extreme4/3.1 board with the 3.00 UEFI version, and unknown CPU (likely a Haswell-E?), without installing the IME software update? Just looking for a data point on that. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

Yet again, it's completely unstable. Didn't do anything, but can't OC at all again. All latest firmware and drivers. No idea why it was OK for today at 4MHz, but then shocking. Unfortunately I can't go back to 3.0 as the bios won't recongnize the firmware file (zipped or unzipped) on the USB (even though it's reading the USB) Really really disappointed in the mobo - it's a very expensive pile of garbage.

Can anyone shed light on the not being able to update BIOS using instant flash issue. Using USB formatted with FAT32 (which I've already used for update once and worked). 1. Download instant flash zip file from http://www.asrock.com/mb/Intel/X99%20Extreme43.1/?cat=Download&os=BIOS 2. Extract to root of USB - gives me a file named: X99EX433.00 3. Boot up - hit F6. It recognises and scans the USB, bat say no disk image is found. What's going on? |

I have tried contacting ASRock support with the bios Instant Flash issue, but have received no reply in 2 days. I am definitely downloading the correct Instant Flash file, and the have tried 3 usbs in different ports, and the unzipped file simply isn't detected as a BIOS image file (I can see the USB is detected, and the file on them is cycled through). Can anyone offer any help at all? |

It sounds like the UEFI update file is the right size. I downloaded the 3.00 UEFI for your board, and the unzipped file is X99EX433.00, and is 16,384 KB in size. Be sure to use a USB 2.0 port on the board's IO panel, when using Instant Flash. Before you try to update the UEFI again, select Load UEFI defaults in the Exit screen, and then Save and Exit. Get right back into the UEFI with the USB flash drive in a USB 2.0 port on the board's IO panel, and try again. If that does not work, or do this first, clear the UEFI/BIOS first, and then try to use Instant Flash. ------------- http://valid.x86.fr/48rujh" rel="nofollow">
