    Default AsRock Extreme 4 990FX bios glitch

    on mine i'm running an 1100T and the latest. any time i manually set my ram speed AND timings it it under clocks my ram by over riding the speed settings.

    so if i set it to 1600 mhz it's all good but, then if i manually set my timings it starts running at 1000mhz (500mhz).


    I've tried and tried and tried again with asrock and they either ignore me, brush me off or pretend to not under stand what i'm saying.

    ----

    Now here is the interesting bit, there was similar glitch with ram speed settings in a prior bios version, however in version 2.50 which i currently have the bug changed. it changed in such a way the problem goes away untill you make ANY changes to the ram timing, then it starts under clocking like the prior bios's bug/glitch.

    I have all but, called asrock over the phone. Yes i just checked and i see there is a version 2.7 which seems to be an ultra fast fix.

    Are you bumping the CPU/NB voltage when changing from 1600 Auto to manual timings? Odds are it's dropping to 1000(500) as it, the IMC, simply cant handle the speed and or timings you're entering.

    The 1100T is native 1333, so much above that and you'll most likely need a v bump to pass.

    I read you thread over "there'. Tight timings with that mem req's some mem and or CPU/NB voltage increase, as witnessed by many many posts concerning.

    Keep in mind i have it manually set to 1600 and have passed over 24 hours of stress testing, it's only when i try to set my timings that the bios wigs out. keep in mind it did something similar with the old bios when i tired ot change similar setting.

    That said, i hear what you are saying and have question to ask. shouldn't it run the speed and timing i tell it too and if it's not stable shouldn't it just to fail to post or boot windows or blue screen and what not? every single system i've worked with ever has functioned this way. it runs at the settings specified in the bios and if it can't handle it, it just fails to run properly.

    Ahhh, exactly what B.F.G. is supposed to do. ASRock > Support > FAQ > What is Boot Failure Guard (B.F.G)?

    Very Interesting. Can BFG be disabled? Also why does it only do ti with my ram? What about all my other insane settings that failed to run correctly? just good enough to pass BFG and move on the next step?

    EDIT: Why did no one at AsRock Inform me of this? Also why does the setting the still say 1600 in the bios? does it only temporarily change the setting? I can boot and reboot but. when i go back in the bios it still says 1600mhz despite running at 1000mhz.

    I can't be positive at this time/distance, but were I to guess with what's known to me I'd say your 1100T's memory controller(native 1333) barfed on th(e)(ose) memory/timing/voltage setting(s) and is possibly the sole reason BFG is kicking in.

    BFG can be disabled, but why?

    The 1600 when in reality BFG lowered it to 1000 I can't say for sure. When it boots back up at 1000 are the timings and or voltage(s) changed also, or are they the same only lower Mhz on the mem? BFG may be "wise' enough to lower to a bootable state w/o the need for you to have a non-booting situation that req's a BIOS clearing and begin your OC from scratch. Again, why disable BFG?

    They, ASRock Techs, may not have "gathered' what was happening over the phone. Doing these things over the phone is near the same as doing it over the net in a forum

    Sorry, missed this one.

    No. It's "permanent' until you go in and change the value(s). Which of course you would, having noticed BFG did it's usual default 1-3 reboots to config to a bootable state.

    I emailed them and even game them a link to the thread with pictures. They also suggested raising the CPU NB voltage and when i asked why they never responded back....ever.

    I'd rather have it crash or fail to post as that's a much better indicator to me than BFG screwing with bios settings.

    It sounds like I'm going to have to come back to this thread when i have the machine together. I'd like to disabled BFG, if it boots with the same issue then we can rule out BFG in which case if it's not BFG... then i would think it would prove my case o na bios bug, IF NOT then technically it would be problem solved, either i'd need to change the setting or the hardware can't handle it... well the IMC maybe because that's nice ram.

    Exactly. Mhz being higher than 1333 and altering the timings resulting in a no boot/BFG situation is usually due to the memory controller needing more voltage to compensate.

    The other side of that coin, but no less important, is the memory itself may need it's voltage bumped.

    Count me lucky(?) but on the boxes I've used this Sammy mem in at default timings, with a 1600 native mem controller/proc, all I've need to do to go from 1600(again, native) to 1866 is set the BIOSes to 1866. Never needing anything more. But you on the other hand are shooting for beyond that there that I just described so you'll need some experimentation for higher Mhz and lower timings.

    Let's talk timings and Mhz. What are your settings your trying that are triggering BFG? Mhz/timings/voltages.

    Oh, on that 1100T of your's and these/this "issue' , have you tried setting the mem at 2T and retry? 2T isn't as bad as it appears and does reduce the stress on the mem controller.

    To those that happen upon that quoted above at a later date, the 1333 I refer is the OPs 1100T's native memory controller.
