mobo cant do 225 bus i dont get this at all.

don't be offended by this get rid of the foxconn board its junk for overclocking

 

[Corduroy_Jr]

The settings go from: 2.50v (stock) to 2.80v. Thanks again, I've been wanting to know this for ages.

Ive found to my experience 2.7v vdda helps a good deal, hope this helps

buy me a new1 lol my next build will be a amd buldozer i hope not dumping any more money into this pc

oh for sure man. same hear holding out to new bulldozer or intel

i got this bored for 2 reasons optical sound for my 5.1 system i had the parts to build another slower rig 2xcore 2gb ram ect just dident have the mobo. + this had a 50$ mail in rebate witch i got

as a heads up, almost all the gigabyte boards have the DD encoding for the onboard nowadays. they also OC pretty well, even their mATX boards.

Will buy one for next build this one had dts aswel and was cheeper then getting the sound card i was looking at. i wont ever buy a foxconn again due to bad support and bad bios. took me 3 months to get a working bios.

Hmm, just find it weird you can hit 3.6 GHz pretty easily and can't even get 3.7 stable.

My sig rig (PII 550) did 3.8GHz out of the box pretty well (slight voltage bump), but 3.9 has been an absolute pain (bootable for a few hours to a day, but not 24/7 stable). It's been my wall since. I've been trying to get cdawall to tell me what his secret was on his 550.

@ xvi & catnip

Try a bump in dimm/dram voltage, but stay less than 2.2v for ddr2 and 1.8v for ddr3. Might help.

 

[MightyMission]

its a shame that foxconn do some abysmal bios,some of there boards are very good!
i will hand my destroyer down to my boy when bulldozer comes out.
its been really good for overclocking,well it will only go 276 fsb but that could well be the 945 limiting it,i think it would be very good with a BE chip so i can use mainly multi for OC then maybe +40 fsb to tighten things up but i have seen destroyers go over 320 fsb.

i will try this when i get home. the ram i have is rated up to 2.3v but I'm running 1.9v

Why with some Phenom II's you can overclock higher while on a 32-bit Windows version; I read about it and I want to try, my cpu won't go past 4.0Ghz and even at that speed it needs loads of voltage.

dont. its bullshit.


the reasoning is simple: parts of the CPU arent in use (the x64 parts) so even if they're unstable, the system may work.


What that really means is that you're running your PC at known unstable settings... which i do not think is a good idea.

 

[MightyMission]

mine takes 1.504 for 4.1,which is high but it spends most the time at subzero temps so i doubt its doing much damage

thats not a bad clock with that voltage good job

cause most likely u reach the max limit of your cpu, if not is some settings set in the bios are not set correctly

the power of christ mussels compels merges you your posts.


also, see my post about why that happens. its no different to only using one channel of your dual channel setup to get higher memory clocks... its not using the unstable parts of the chip, so it seems stable when its really not.

 

[claylomax]

Thank you for your answers but I'm still curious why my cpu can do 3990mhz but not 4004mhz. Based on Mussel's answer I don't think I'll install the 32-bit version of Windows; but since I added a second GTX 480 I want my cpu to downclock when idle, something that's not possible past the 18.5 multiplier.

if not is some settings set in the bios are not set correctly

Such as?

because you hit a limit. if it works at 4004, why not 4008... and if it works at 4008 why not 4012?



mine downclocks fine from 3600->800 with no issues, not sure why yours has limits like that.

Mine also, the problem is when the multiplier is set to 19x (3800mhz) it won't downclock even if C'n'C and C1E are enabled.

 

[MightyMission]

my pc will not POST if i disable cool n quiet,the bonus of this is i still downclock when not needing the increased speed.
the wall may not be there until further up the scale if you turn the CPU multiplier down and increase FSB,or vice versa.
there is a power saving option in windows too,this may or may not be enabled.

 

[Jack Doph]

All of this may be related to some degree, to the quality of the chip in question.
My 965BE is rock solid at 19x, but even 1 MHz more and the system fails, no matter what else I throw at it (voltage, RAM relaxing, you name it).
So.. it's all pot-luck really.
I must say that Mussels is certainly correct about the difference between 32-bit & 64-bit.
Your system may well be unstable, but a 32-bit environment might never pick up on that..

They don't need to be adusted from Auto or stock for any reason.

It's the CPU-NB voltage you adjust right? I just didn't see that option in his BIOS though, or did I miss it?

 

[catnipkiller]

my bios made me rage when i first got my mobo like RAGEEEE. the support team had to test the bios witch took them 3 months then they emailed me the bios but wont post it on the websight. anyways i dont get why my nb volts look so high on my bios but lower in amd over drive. and fan speed will not work at all on my mobo. over all i al not happy with foxconn.id say everyone should stay away from them.

There's always the chance that some mobos can live happily ever after *without* a voltage increase.
Chances are, though, this is rare.
An increase, no matter how slight, would be the recommended course of action for sure.
