QUOTE(kuntawakaw @ Nov 30 2011, 01:53 PM) i limit myself for until 1.45v only.but i cant really recall what the exact vcore for that. im on air cooling. ninja3 i pump to 1.55 directly.... dun want waste time on oc... but the 8120 dont scale very well, 4.3Ghz hard to boot already. if yours the same, then its not my chip lemon then oc with this chip gonna cost u very much electric bill 8 core is damn more than enough |

QUOTE(kuntawakaw @ Nov 30 2011, 03:18 PM) the turbo core for 1core how high eh? i also donno that is 4900 wor...[attachmentid=2560367] manage to get this speed with "still safe vcore" but it wont last survive any benchmark i think. no time to oc now i guess my 8120 is the limit. increasing more vcore also wont help. yours also the same i think. just you luckier then me. got 300Mhz faster kekke |

QUOTE(LittleBear @ Nov 30 2011, 04:40 PM) I have got a 990FX board running Phenom II 1055T (3.5GHz) with it. I guess I'll wait till Piledriver for the next upgrade. it will delay a year later.... about the oc.. i think it is cause by the mobo... need more phase power to boot higher clock... just guess only...

QUOTE(howszat @ Jan 1 2012, 08:26 PM) Noob here. lower your memory and lower the hypertransport as well... search google read more oc guideGA-M55S-S3, AMD 64 X2 4200+, Kingston DDR2 2G. There plenty of advice on what to do with multipliers and dividers on CPU, HT etc, but on my mobo, there's only the "CPU clock ratio" (x11) - and no other options. All the other adjustable BIOS options are to do with voltages, ranging from +0.025V to +0.37V. I've increased the "CPU frequency" to 218Mhz, but any higher it will not post. What can I look at next? |

QUOTE(howszat @ Jan 1 2012, 08:35 PM) There are no options to lower the memory multiplier or ratio. No options means your board doesn't support overclocking..... So what exactly do you mean by "lower your memory". As I said, there are no other multipliers to change on this mobo BIOS. These are all the options I have: cpu frequency mhz: 200 - 500 pcie clock mhz: 100 - 200 cpu clock ratio: 5 - 11 ddr2 voltage control: +0.025V - +0.275 white +0.300V - +0.475V red chipset/pcie voltage: +0.025V - +0.375V ht link voltage: +0.025V - +0.375V cpu ht-link voltage: +0.025V - +0.375V cpu voltage control: 1.5500V - 0.8000V |
