  • MSI 745 o/c help

    ok got myself a MSI745 today. the reason is here. already love it!

    unlocked the multi, and did some serious o/c. as of now my XP 1600+ AGOIA runs at 1680Mhz (12 x 140). memory is some cheap hyunix or sth. CL2.5 PC2100. vCORE 1.800, vMEM 2.7V, mem timings: normal-6-3-3. it did 5-3-3 up to 138Mhz.

    i might try to push the FSB 1,2 or 3 Mhz higher but first i need to know: is it safe to set vMEM to 2.8V? and if yes does it help? and what are the hidden (F3) memory settings good for?

    and sth. is strange: the system wont boot at mem 5-2-2 even if the FSB is at 100 i have to clear the CMOS. bios is 1.3

    did run superPI a few times and did some UT2003 demo loops, rock stable so far

      ok i'll try one more mhz if it doesnt work i'll keep it at v2.7, i think 1680Mhz is good enough from 1400Mhz nice stepping it seems

        1703 really amazing. 12 x 142, i'm not going any higher. the msi745 was really worth every penny , my k7s5a only let me do 10.5 x 143 (1501) stable.

        in wcpuid it shows that the chipset supports side band adressing but it's disabled. is there a way to enable it and does it increase gfx speed at all? also in the mem settings options in the bios there is spread spectrum and the option below (stop/action), are both best left disabled or enabled?

          I have Spead Spectrum enabled and Stop on the mem.


          Sideband addressing is enabled here

            hmm the nvidia display thingy shows chipset support SB, gfx supports SBA but it's not enabled. there is also an option "enable sba" but it turns off when i click ok same for agp rate etc. - i need some MTSTU for nvidia cards now

              Try PowerStrip. With this you can enable Sidebanding and Fastwrites without even a restart needed (but it might be that your sytem will do a "forced restart" (crash ) if you set those values....)

                enabled it with rivatuner. tried 144 but it will bluescreen eventually, even with more vcore. and fw is not supported.

                              Those are really nice results with a Zalman 5000 cooler. I guess you value the lack of noise, but also want to overclock. If you can afford it, try getting a Thermalright AX-7 or SLK-800 and sticking a low noise 80mm fan on it, think you could eek a few more MHz that way.

                              If you are looking for new RAM, try Samsung. Lucky pick could get you 180MHz+ at decent latencies.
