  • F3-14900CL9D-8GBSR + GA-990FXA-UD3(f6f) w/ AMD FX-8120

    Not completely sure if I have it dialed in completely. Boots great and runs pretty snappy but an occasional BSOD makes me nervous.

    ^^^^Set by DOCP @ 1.5v

    CPUID CPU Name AMD FX(tm)-8120 Eight-Core Processor
    CPUID Revision 00600F12h
    CPU VID 1.2625 V
    North Bridge VID 1.2125 V <-- thats with .075 bump in voltage

    CPU Speed
    CPU Clock 4228.0 MHz (original: 3100 MHz, overclock: 36%)
    CPU Multiplier 21x
    CPU FSB 201.3 MHz (original: 200 MHz)
    HyperTransport Clock 2214.7 MHz <--- This is set by DOCP @ x11 FSB
    North Bridge Clock 2214.7 MHz
    Memory Bus 939.6 MHz
    DRAM:FSB Ratio 28:6




    Question #1 is should I lock down FSB to 200 (for stability)
    Question #2 Can this RAM run 9-9-9-26 or 27 and be a bit smoother or are those timings riding the proverbial line so to speak.

    Afterthought this should be moved to Overclocking AM3 sub-forum due to its nature.

    Looks pretty good. Not sure what the BSODs are, but might simply look to raise DRAM, NB VID or CPU voltage just a touch (prob no more than .02 on any of them...Might start with CPU VID and if still get them, then drop back and try RAM else CPU....if you catch the BSOD error code, let us know

      Hard to nail down the BSOD's since I run SSD with no pagefile. It could also be running a G15 with all my temps on keyboard it could be polling the mobo enough to cause instability. When I get my Antec 920 Kuhler I will bump up the v's a bit to see if it runs a few passes of prime95 (2 hours at least blend test)

      I will update my results.

          thats 4ghz with the memory set at 2000mhz and running smooth so far. I have tons of airflow in this case so its pretty safe. I might try pushing the cpu more at a later time but Im pleased with this so far.

              Made a slight change after getting 4.279ghz. The ram setting 110ns ---> 160ns! Seems to slow it down just enough to remain stable under the heaviest of loads.

              I think all I lack in this build is a 1200w PSU. 850w rides the line with an SLI config and a bulldozer.

                850 might be marginal depending on the make/model, when you look at PSUs make sure whatever is advertised i.e. 850 is not the MAX load (many PSUs adverise this way) but is basically the normal load, an 850 max may be more like a 700 normal load

                  I am late to provide good input, but I have to say you did a great job, I will move this to Overclocking section because it has very good info people can use.

                  With this memory kit, it is probably better to raise frequency instead of lower timing, as you have done. Especially with your CPU OC, the high DRAM frequency should benefit nicely.

                  Thank you

                        Still no BSOD

                        Summertime and I dropped the multiplier to 4.0ghz and one notch down on cpuV.

                        Don't really have to with air conditioned house but I'm a stickler on load temps.

                        Ran fine even with the liquid at 42c would say that on a super cold day with the windows open I could pull a 5.0ghz for testing with these results.
