Overclocking AMD Phenom ii x4 955 Deneb (NOT B.E.) Tags: AMD Overclocking Phenom Last response: January 31, 2013 1:09 AM in Overclocking Share sLepK January 29, 2013 1:59:14 AM AMD Phenom ii X4 955 (Deneb) Biostar A870U3 ***** Cooling, heatsink, psu, all good -- just trying to figure out what my first step is here. I downloaded AMD Overdrive and it won't let me up the clock core multiplier any higher than it comes stock: http://i.imgur.com/f6GCnaa.png So what is my first step here? Do I have to unlock my processor or what? I'm not going for anything crazy here, would like to get a 3.6-4.0 OC.

Read some guides, don't be afraid to use google there are tons of excellent guides available for OCing a 955. All 955's are black edition chips, anything below a 955 in the phenom II x4 line is not a black edition. | Report abuse Reply to mlcaouette sLepK January 30, 2013 4:18:07 PM mlcaouette said:Overclock via bios only!

Well I've been in the BIOS several times, and when I get to core multiplyer after enabling custom p-states, the highest value is x16 (3200mhz). So what am I dealing with here? Again, mobo is A870U3.

The board was not intended for overclocking (it uses a 3+1 vrm with no cooling on it). Buying a different motherboard would solve your problem, in the meantime I wouldn't push your overclock too far unless you want to fry the motherboard and possibly other components as well. Here are a couple of threads dealing with the particular board in question: http://www.overclock.net/t/1050385/biostar-a870u3 http://hardforum.com/showthread.php?t=1650724 | Report abuse Reply to mlcaouette Register or log in to remove Ask the community Post an answer Tom's Hardware>Forum>Overclocking>Overclocking AMD Phenom ii x4 955 Deneb (NOT B.E.)> Related ressources: ForumGTX 570 + AMD Phenom II X4 955 Deneb ForumBest Memory Pairing for Phenom II X4 955 Deneb ForumAMD Phenom II X4 955 Deneb 4.00ghz Forum$350 Build with AMD Phenom II Deneb ForumUnlocking Cores AMD Phenom II X4 955 ForumAMD Phenom II X4 955 Future Proof?
