Hello,

I have the gigabyte x58 ud7 motherbostf an i7 920 chip and patiot 1600 memory

the overclock consisted of nothing more than stick the multi to 21 and the bck to 200 and the ram voltage up to 1.64 volts

the ram timings and everything else were all left completely default

this has run fine under 100% constant load for 24 hours then all of a sudden it froze then rebooted

i was going to ask if i could tighten the ram timmings up again as the auto has loosend them a lot
but seeing as how it just froze on me i want that problem fixed first

anybody got any ideas why it would be so happy for so long under load before out the blue freezing and re-booting itself ?

best regards
Ian
 
Hi, You ran it 24 hours? mmm imo i would say thats stable you will never get a overclocking stable imo, it depends what you want to use your computer for really... like mine, mine crashes.... atleast once every 2/3 weeks but i game and i dont mind, but if your video editing ect, i wouldnt overclock atall :)

So if your just gaming i would keep it that.

hi,

no i use the rig for modeling so it can be on constant load for weeks even months and if it crashes i loose models so i want it stable really

ive never heard you couldnt have a stable overclock i thought everybody in here had them and not just peek to peek clocks as it were

Use something like LinX or Prime95 to verify your overclock is stable, it's perfectly possible to get a stable overclock if you do the right testing and don't just take the "if it runs what I want it's fine" mentality.
 
i've got the ud7 and i thought i had instability; upped various voltages, no dice. put it back to stock, still get random blue screens...

i think these boards need a bios update!
 
hi,

thanks everybody, does that mean you can put to much volts into a memory overclock ?
i thought you had to up it a tad to cover all the extra work ?

i thought the whole point of overclocking was to get it so it did everything you wanted without crashing ?

does prime95 not just run huge numbers through itself ?
basically the same as my modeling

hope the board doesnt need a bios update

You'll find there are two types of overclockers, those such as myself who believe overclocks should be no less stable than at stock and those who just want the highest clockspeed possible without any catastrophic crash.

Yes it does but unlike your modelling it will push your CPU to its max and also has error checking, so if your CPU is getting its math wrong it will stop and tell you rather than just carrying on as if everything is normal, same goes for LinX.
 
LinX is also good. If you're failing either you need to work on the overclock.

I'm in the first group mmj describes, and spend a long time stress testing because I really don't want it to crash and lose my work.

Bear in mind that for a stable 4.2 ghz you're likely to need to set several settings in the bios by hand, and not leave them all on auto.

This logic is infallible. It's quite true that, if your computer crashes after 24 hours, it's stable. Oh wait..
 
hi,
i actually tried prime and it failed in about 3 mins freezing then re-booting again
i found out that the memory actually should be taking 1.65 volts
i had taken it from the default 1.5 on the bios to 1.64 volts which wasn't even the memories working voltage ( close enough lol )
the cpu voltage which i had left at default i put up one notch to like 1.28 and wondows wouldnt even start
so reduced it down to default again so it would get back into windows
so i take it once you have the ram at manufacturers stock voltage and the cpu at its default voltage you can only then clock with what your given voltage wise ?

still testing various overclocks with various means of getting them but prime takes a long long time to run its tests so its a long wait to see if youve managed it

must admit it is rather funny that the cpu refuses to take any more than stock voltage

best regards

hi,

just thought should i maybe change the timing from 1t to 2t to see if that makes things more stable ?

sorry about all the questions
Ian
 
there's a new bios (f3) for this mobo on the gigbyte website; i got it last night, dialed in 4GHz, passed prime for 30 mins, which it's never done before on any setting. seems way more stable than the release bios.
