do ASUS Crosshair V Formula can enable FX 8350 in 4C/4M mode?

post #1 of 2
Thread Starter 
Hi guys,can u who can clarify my problem stated as the title i post? i just buy an FX 8350 and want to disable each core in each module for minor additional performance for my old games which only using 2-3 cores only.My board is already update the latest bios,1703 and when i see the setting "CPU CORE ON/OFF FUNCTION" in the bios,which let me to disable independent each of the cpu core.

Thus,after i make the 4C/4M mode,i save and restart my pc until into windows,(im using windows 7).....suppose it only showing 4 core on the task manager right? BUT IT UNFORTUNATELY NO AVAIL,it shows 8 core,not 4 core.Same also when using cpu-z and amd overdrive software.

So my question is:
1)what the point having the function in the bios if no core is being disable?
2)Are the function is only for the 1st gen bulldozer fx? not piledriver?
3)Or i need to wait the hotfix bios?

Can u guys help me?cause im waste buying this board if only OC is best,because i like to testing new way to improving the cpu performance beside OC the CPU.

these guys can help you with questions about your board- http://www.overclock.net/t/946327/official-asus-crosshair-v-formula-990fx-club

the reason you disable cores is to reduce heat and push a higher OC to the CPU. normally you want to run all cores at highest stable OC without having to disable any of them. the cores might not disable until CPU is under load (won't see it at idle) but I honestly didn't play with that on my board (has similar options). but even if you disable them, they are still going to show in monitor programs like overdrive, they just wont be active.

if you post in the link I gave you, use rig builder to enter specs for your PC and edit signature to show rig. it'll help people know what hardware you have and what not. thumb.gif
