Hi, This is my first post on this forum, my compliments on the forum and it's color combination of black and gray, they are easy on the eyes. I have ASRock's H81 Pro BTC motherboard, I used GPU-Z's render test to check if it's PCI-E lane can run at 2.0 x16 but it wasn't, it was only running at 2.0 x2, someone on other forum suggested I disable any power saving features in UEFI's Advanced page, I had 1.90 UEFI update and I didn't see any such option, thinking it might be in a new UEFI update, I downloaded the latest UEFI update for my motherboard from ASRock's website and used it, after updating, in the OC Tweaker settings page, there was no option to change the clock and cache speed of my processor, G3258. Am I not seeing something or is it removed in UEFI's 2.10 update, I had 1.90 and I skipped 2.00 and directly updated to 2.10, could this be cause? Is there a way to get back the overclocking option? What can be done about PCI-E 2.0 running only at x2? Thanks |

OH NO!  I believe you are a victim of the removal of the non-Z OC feature your board had at one time. Confirm this for us Xaltar, I know you have dealt with this in the past. Before I explain that, did or do you have a Turbo option in your past or current UEFIs? While the G3258 does not have Turbo Boost, it must have Turbo enabled in order for it to be over clocked. If you never had a Turbo option in your UEFI, then it was only shown when the CPU had Turbo boost, or the G3258 was being used. Back to what I think happened, if the above does not fix your issue (I doubt it will.) Intel was not happy about the non-Z OC feature your and other boards had. They forced ASRock to remove it with a BIOS/UEFI update. Guess which one that is? Yes, version 2.10. Note the description of UEFI version 2.10: Update microcode 19. Microcode is used by the processor for various things, including determining what it can and cannot do. Microcode 19 turns off the loophole that allowed non-Z OC (your H81 chipset board does not have a 'Z' chipset, like a Z87.) Can you change to a different UEFI that replaces the 19 microcode? In theory yes, but the microcode is not changed in every UEFI update, only certain ones. Plus this special 19 microcode may permanently lock out the over clocking feature/options. I DON'T KNOW if this will work, it may do NOTHING: UEFI 1.20 added support for new processors, which normally means a microcode update. So apply UEFI 1.20 with Instant Flash (please), then update to at least UEFI 1.80 that added support for the G3258, but only up to UEFI 2.00 of course. Otherwise the only known fix is to buy a new BIOS/UEFI chip for your board. It's in a socket in your board so can be removed, but very carefully, research doing that first. The chips can be found on places like eBay. They usually let you choose what BIOS version to be on the chip when they send it. The price is... $10 or $15 I think. Notice this happened almost six months ago, the special UEFI released to remove the feature. Intel even had Microsoft create a Windows update that does the same thing! So you could still get zapped with that update unless you turn off automatic updates, and check for the offending update. This is an example of why it is a good idea to read through the mother board forums at least every now and then to learn what the latest nonsense going on is.  ------------- http://valid.x86.fr/48rujh" rel="nofollow">

No, there was no Turbo option in past UEFI, 1.90. I'll try what you suggested. |

So I've updated to 1.90 and it restored the OC settings. |
