Hi. I just changed to this CPU, and I'm trying a overclock it, but I'm really dont know much how it should behave. Most posts that I read, people say that it should make 4.5 stable at 1.38 to 1.45V, but here on tests, I need increase voltage up to 1525mV* to get it stable. * Actually its 1525~ on idle, but on load it drops to 1488~mV My motherboard is a Gigabyte 970A-DS3P latest bios, but I feel like it dont have a good control over voltages, and even clocks, I will list what I feel that is like a little strange to me. First, BClk is always 200.92mhz, and it makes other clocks a little of, like RAM, that is at 937, instead of default 933, HT at 2411, CPU on 4520, instead 4500, etc. Also, sometimes CPU just drops to 4488 or something like that (on CPU-Z) or sometimes 4675 or something like that, its random I think. I dont know if this is something related to "spread spectrum" or something like that, but I didn't find this option on the UEFI. Other thing is that, like I said, voltages are a little weird, drops on load, etc. VRM with +240mV, 4.5GHz, dont get very hot, 45C mosfet heatsink, I measured with a laser thermometer, and inductors at 60C~ I need +240mV to have a stable 4.5GHz on prime95 - I can boot up at 4.8 with this voltage, but it fail on Cinebench, I dont even tested prime at this frequency. +240mV at 4.5, with my water cooler it gets at 52C max - On AMD Overdrive (assuming that is 70 max temp), its not bad I think, but like I said, many ppl said that 4.5 should be stable at +100mV, 150mV or something like that.. idk.. I cant overclock NB, at all - even with +200mV, at 2200mhz, it just goes weird, even trigged one time the dual bios recovery on the UEFI. Also, I'm using DDR3 1866 memory, Hyper X Fury, single rank, 2x4GB - at manual 1.55V, because the auto mod, sometimes set the voltage to 1.45V, reports on AMD Overdrive at 1.47, so I bumped to 1.55 I dont know, it seems a little off, this results, should be better or I'm missing something?
