Hello all, what i wanted to know is how do i disable 1 core per do module on my Asus crosshair v formula motherboard, i i have been reading around few foruns and i saw someone saying that a "special" bios is required. Where can i find that bios? the thing is i wanted to increase my single threaded performance on my amd fx 8150 cpu so that i can properly emulate wii console using Dolphin emulator, since it only uses 2 cores and relies on single threaded performance it slacks a bit on my cpu. could you help me plz?<br>
best regards<br>

I am pretty sure under the CPU Feature part there is an option for how many cores you want to run. I don't have your motherboard so I can't be positive, but just look around and it should be there somewhere. Every motherboard I have had has had the option to choose how many cores to run.

There is an option to disable/enable cores, but what i am looking for is to disable 1 core per module, not disable modules.<br>
thanks for the reply anyway <img alt="smile.gif" class="bbcode_smiley" src="http://files.overclock.net/images/smilies/smile.gif">

Right now only AsRock has that option. You will not boost preformance by disable 1 core per module in any form.<br>
I had an AsRock and tried it for the fun of it.

The CHV-Z definitely won't do that and I'm not 100% sure if my CHV does or not. However that's easy to do and I'll just pop in one of my FX chips to see.<br><br>
I'll need to doublecheck and confirm it but I believe my Sabertooth R2.0 does - I seem to recall doing just that with it once before. <img alt="rolleyes.gif" class="bbcode_smiley" src="http://files.overclock.net/images/smilies/rolleyes.gif">

i just now it is possible, with a modded bios, but i cant find it...

In LINUX there is a instruction that we can give in the Terminal that disables as many cores as you want....no need to reboot either , it starts to work right away....in fact, IIRC, cores will be re-enabled in next (re)boot.<br><br>
Never used for AMD only for Intel but AFAIK, it should also work with AMD APUs/CPUs.<br><br>
I used to use it in a PC running LINUX and using WINE to play CoD2....CoD2 under WINE have problems with videos and multi-core CPUs that would make it crash, solution was before launch CoD2, open a Terminal and issue the instruction to disable all cores minus 1 and then launch CoD2.<br><br>
After play CoD2 i enabled again the disabled cores.

Had to post this up. <img alt="biggrin.gif" class="bbcode_smiley" src="http://files.overclock.net/images/smilies/biggrin.gif"><br><br><a class="H-lightbox-open" href="http://www.overclock.net/content/type/61/id/1809754/"><img alt="" class="lightbox-enabled" data-id="1809754" data-type="61" src="http://www.overclock.net/content/type/61/id/1809754/width/350/height/700/flags/LL" style="; width: 350px; height: 263px"></a><br><br>
I did say I thought I'd seen it in the Sabertooth BIOS before and here it is. However I don't know exactly if it's something you can do at will or if it's a BIOS glitch making it happen.<br><br>
Anyway, here's how it happened - I started out at stock settings with only 2 cores going. I loaded up an OC profile and booted with it - I then saw once the OS was loaded and I had opened CPU-Z that all 8 cores were going. Didn't want that so I rebooted, went into the BIOS to switch off the extra cores and this appeared.<br>
Hmmm... <img alt="headscratch.gif" class="bbcode_smiley" src="http://files.overclock.net/images/smilies/headscratch.gif">

crosshair v formula-z board with 2101 bios<br><br>
sure would like to be able to disable each core like in the picture above.<br>
I would like to have 4C/4T and not 2C/4T<br><br>
I am trying to disable 1/2 the cpu to save watts till I get a better psu as the gtx 770 im using would use just to much with my psu<br><br>
in this thread <a class="bbcode_url" href="http://www.hardocp.com/article/2012/10/22/amd_fx8350_piledriver_processor_ipc_overclocking/6#.U7qSTekg-cx" target="_blank">http://www.hardocp.com/article/2012/10/22/amd_fx8350_piledriver_processor_ipc_overclocking/6#.U7qSTekg-cx</a><br><br>
hes using a CVF-Z board and he says this<br><div class="quote-container"><span>Quote:</span>
<div class="quote-block">Try disabling cores:<br><br><br><br>
disable cores 1,3,5 and 7 for optimal performance (Cores 0,2,4 and 6 remain active => 4CU/4cores active)<br><br><br><br>
disable cores 4,5,6 and 7 for optimal OC (Cores 0,1,2 and 3 remain active => 2CU/4cores active)</div>
</div>
<br>
so it does look like at one time this could be done correctly?
