    Question 4ghz settings for ep45-ds3r

    hi,

    I'm just after some OC settings specific to my system for a nice 4ghz OC. I am currently getting 3.75 ghz stable previously on 1.325 volts with 500mhz fsb at 1:1 with mem for ddr2 1000mhz at 5-5-5-18 on stock hsf. The only settings I really changed were vCore to 1.325V, dram to 1.9V and mch to 1.2V. However as i got my new hsf and wanting to bump it up, I'm having problems getting stable at 4ghz (i'm just bumping up the vcore to about 1.38) and I think it may be either volts or memory settings related. I tried some settings i found elsewhere and got this board running fine at 4ghz on only 1.3V vCore (was 1.25 under load). It OCCTed for 1hr but failed to even start Crysis Harbour/Assult demo loop benchmark =(.

    Specs of importance are as follows:
    cpu: e8500 e0 VID 1.25
    hsf: xigmatek S1283
    ram: 2x http://www.corsair.com/_datasheets/T...096-6400C5.pdf (i.e. 4 sticks of 2gb ddr2 800 currently OC to 1000mhz @ 5-5-5-18)
    psu: corsair 620w
    vga: 4870x2 @ stock (constant 50% fan speed)
    rest: 1 hdd, 1 dvd-r, ~5 120mm case fans (3 in, 2 out), antec 300 case

    I believe i have a fairly decent system and i just need some settings to guide me to a nice 4ghz stable oc please! my system at 3.75ghz is only 45 deg C under full load with the new hsf (from 63 deg C with stock hsf) @ 25 deg C ambient temps.

    My settings for 3.75Ghz are as follows and I'm running latest F10 bios. Any assistance would be greatly appreciated from gurus.

    Try this for 4Ghz, vcore of course will be up to you to find >>>>

    This will have your ram at 900, so you can run tighter timings. If you would like some settings for a lower CPU multi let me know

    Hi,

    I managed to get it quite stable OCCT 2 hrs+ with these settings. Any more optimisations I can do? I really wanna run my fsb at 500 so used 8x multi. My system was OCCT stable for 2 hrs at 1.325 vCore and 2.0V ram but running Crysis assault/harbour timedemo would crash the game. I think due to me having a 4870x2 and a 620w psu, the load from the graphics was drawing too much from the psu and causing it to undervolt the cpu/mem. I tested this theory by bumping up my ram volts and cpu volts to 2.1 (from 2.0) and 1.35 (from 1.325) respectively. Lo and behold the timedemo ran fine and looped 20 times. I left it OCCTing over night and if it passes that I'll be happy as pie. Will keep you updated when i get home. I think my ram at 2.1V might be a bit high? But bear in mind i have 4x sticks and a 90mm fan blowing across them.


    Cheers.

    Looks good. 2.1V will be fine, especially since you have a fan on them.

    Yeah you can try lower MCH and this >>>
