    Unhappy HELP with my rig: Crosshair V Formula + AMD FX 4100 + Eventual overclock

    Hello everyone,

    After putting up my new rig using all the parts I had gathered in the past few months, I noticed the RAM was not working as per specifications. I would need some directions as to how to make it work the way it should.

    First things first though, here's the details for my machine:

    Motherboard
    SMBios version 2.7
    ASUSTeK Computer INC. Crosshair V Formula Rev 1.xx
    Bios: American Megatrends Inc. 0705 08/22/2011 taille: 4096Kb
    Chipset
    North bridge: AMD RD9x0
    South bridge: AMD SB910/950
    Processor
    AMD FX-4100 Zambezi Socket AM3+ (942) (@32 nm) 3600 Mhz ( L1I: 2 x 64 Ko, L1D: 4 x 16 Ko, L2: 2 x 2048 Ko
    , L3: 8192 Ko )
    Memory
    Physical memory size: 16384 Mo, Type: DDR3, @MHz, 9.0-9-9-28--1T
    DDR3 G.Skill F3-14900CL9-4GBSR 4096 Mo PC3-12800H (800 Mhz) (9.0-9-9-28)
    DDR3 G.Skill F3-14900CL9-4GBSR 4096 Mo PC3-12800H (800 Mhz) (9.0-9-9-28)
    DDR3 G.Skill F3-14900CL9-4GBSR 4096 Mo PC3-12800H (800 Mhz) (9.0-9-9-28)
    DDR3 G.Skill F3-14900CL9-4GBSR 4096 Mo PC3-12800H (800 Mhz) (9.0-9-9-28)

    Graphics card
    AMD Radeon HD 7900 Series
    ATA devices
    WDC WD2002FAEX-007BA0 05.01D05 (SATA II, 1.82 To)
    WDC WD3000HLHX-01JJPV0 04.05G04 (SATA II, 279.46 Go, Cache: 31 Mo)
    WDC WD6000HLHX-01JJPV0 04.05G04 (SATA II, 558.91 Go, Cache: 31 Mo)

    The RAM should actually be running at 1866Mhz but whenever I try to change that in the BIOS by using the drop-down menu that is provided in the Extreme Tweaker tab and I save the settings, Windows 7 won't start. I'm thinking the voltage might be set too high when I try to edit the settings that way. As you can see, the timings are 9-9-9-28 when they should be 9-10-9-28. Similarly, the DRAM voltage is set to 1.65v (according to the BIOS) when it should be set to 1.5v. Somehow it makes the RAM run at 1600Mhz.

    My question is: is it possible to bring the RAM to 1866Mhz by setting the timings to 9-10-9-28 and the voltage to 1.5?

    Thanks in advance to all who will reply. I will not be able to see your replies until next weekend (it's Sunday night here).

    Have an awesome week.

    May I suggest you have a read of some of the overclocking guides. I am sure you are familiar with most of what will be covered within those guides, however there is mention of how to increase the ram speed. What are the settings you have changed in the bios?

    Without those details it is very hard to suggest a fix or possible option to try.
    3 series MIVE, MIVG BIOS FLASH GUIDE
    RAID GUIDE * Memtest86+ GUIDE * CAP GUIDE * USB BIOS Flahsback GUIDE * Win8 Rampage Install

    ONLY IF 2003 BIOS or NEWER
    To Flash back to 1xxx.ROM, Rename 1xxx.rom to ERALL.ROM and Use USB Flashback
