ex58-ud5 overclock boot issue

[kilner]

ok my problem is after i do some overclocking on this mobo i get the cold boot issue


power off power on power off power on then i check bios and it says overclock problem and resets my setings i put my setings back to my overclock thats tested in prime95 occt and linx stable press f10 and boots to windows and runs perfect

the problem is every time i shut down and press the power buton it starts the boot cycle loop and then i hav to re do all the bios setings again

i hav the f12 bios also did alt + f12 to update the second bios

i also hav an identical ex58-ud i7 setup runing identical setup and this setup dosent do the reboot cycle with the same kind of overclock

i understand that each system is difrent and requires a difrent overclock

on the mobo with the problem u go in bios set the setings press f10 the hit enter the system fully powers down then starts then powers down then starts and boots to windows with the overclock


the second system runing the same bios f12   i go in set the settings hit f15 then enter the computer restarts but it dosent power down or do this boot cycle that the problamatic board is doin



i thort it could be my psu so today i removed both boards and installed the mobo thats runing fine into my problem rig and its still runing perfect on that psu

so this leads me to belive its a mobo problem

i hav tri channel ocz 2000mhz ram and a set of corsair xms 1600 mhz ram tested both and still the same problems


the only difrence betwen both of these mobo is the pce-e 8x slot   on the problem board its orange and on the mobo thats fine its blue both boards are revision 1.0

i contacted gigabyte was told its bios setings  this is complete fubaaarr also contacted overclocker.co.uk and was told it carnt be RMA if its working corect under default setings

i duno were i stand on this but im 100% sure its a faulty mobo


rig info

i7 920 D0
ex58-ud5
corsair hx 1000w
ddr 3 tri 2000mhz ocz/1600mhz corsair (obv not runing at the same time)
2x 6870 crossfire
corsair h100 cpu cooler


the systems are 100% stable in windows

please any advice or help would be fantastic

Hi and welcome to the Gigabyte Forum.

Maybe you can give us a bit of added info to help out hopefully.

How much memory and what configuration/timings/voltage are you running ?

Why do you totally dismiss that it couldn't be anything to do with BIOS setings ?

Have you tried with only one GPU running (not crossfire) ?

[kilner]

i kno its nothing to do with my overclock setings or voltages

i think the main problem is the 1600mhz ram

atm im on my ok pc and carnt test


i still hav my perfectly fine running mobo in my faulty rig

im sure wen i set my ram to 6x its runing ok but i rly dont c why i hav to run my ram slower just so the bios will save setings

and that on my other ud5 it will save my setings with all the same parts


im goin to put my faulty mobo back into this sytem and do some more testing

im 100% it is the mobo and no other part in my pc causing the problems

thank you for the response sry if im coming over as a bit of a tool but just so annoyed atm

  With the added information that DM requested (yes very useful it would be) can you also include the Voltage of the memory (as in what V you are using) and the QPI/VVT voltage at the clock your having troubles with

  Frustrated tools are acceptable on the forum ......

after a bit more testing it seems its me and not the mobo atm it still has a weird boot cycle unlike my other ud5 but it isent reseting my bios now


even tho i was super stable in windows it seems my timings were to blame i had them to tight   7-7-7-20 t1  changed to 8-8-8-24 t1 and seems to be saving my setings now

if i continue to hav problems after a overnight power off i will update and give the full details of my settings but i hav been working on this for weeks and also googled every bios seting indavudally to make sure everything was correct


just strange ones in windows im stable at tight timiings yet it causes a problem from power down boot

   Two points!

  Glad you got it worked out!

well my sucess was premature

powerd down went for a walk pressed the power button and then the same 3 cycle boot sequence hit del to get in bios and it had failed


it rly is beyond me works perfect in windows and on all the stabilty tests

then im plagued with this

is ther any setings i should try at default ? 

to test if its the mobo thats at fault ?

i also swoped the battry with the one on my other mobo that works fine

[Aussie Allan]

  It's starting to sound like a memory issue to me to be honest!.....can you give me the full spec of the memory that you have in the machine that's giving you problems .....8.8.8.24 ...running at ? ? ? ? Mhz

i hav a set of ocz and corsair and both hav teh same issue in this board but if i put them in my other ud5 ther is no issue at all this is wats making me think its the board


the code for the ram atm is CM3X2G1600C7 aparantly it should run at 1600mhz and 7-7-7-20 timings also run memtest and the windows memory test all fine

[kilner]

another update sry for the spam but im leting you kno the info as im testing



changed an option in my bios call memory performance or somthing like that  the options it gives you is standard , turbo , extreme

i had this set to standard just changed it to extreme and so far so good 

but wat does this actually do ? i hav manually set timings and voltage

but so far it must be doin somthing

[Aussie Allan]

  Probably make you system even more unstable ........I thought you were trying to find the problem ....

[kilner]

i am trying to find the problem but belive it or not that seting is working


u dont no how much i hav tryed to find this problem its such a weird problem but i hav tryed everythin people hav sugested to others asking this and it neva fixed my problem


atm im telling you this seems to hav cured it

  PC god syndrome

  if it passes  OCCT  (or simular) over night it's stable .... good luck Jim!

  Aussie Allan

[kilner]

it does pass 2 hours on occt 3.1.0

20 passes on linx

5 hours on prime95

memtest86  left for 2 hours no errors

btw the memory thing seemed to help but then it made it worse its very strange seemed to take around 6 boot cycles with it on extreme


iv changed all componants from my ud5 thats working perfect and still the same issue if i overclock to 3.2 or 4.4 its teh same problems with the boot

[kilner]

SOLVED


thanks for taking your time to respond


im super noob and expected more of my 1600mhz ram the issue was 210x21 = 4.4 = 1680 overclocking the ram to much and causing it to be unstable 200X21 = 4.2 @ 1600 runing perfect now


so yes im a super noob and wasted every ones time including my own
