    How do I o/c on my NF7-S

    How the hell do I get my nice spanky new NF7-S to o/c my chip back up to 2400 like I had it on my creaky old 8KHA+?

    I've got a Jhuib, or whatever it is, Athlon... which has happily clocked up 2600 before but I usually run it at 2400... now I can't seem to get past 2000 without a freeze on POST...

    I've searched the forums and read all about how great the mobo is ofr clocking, but I cant seem to get this baby going no matter what!

    I want my 6135 3D mark 2003 score back! (which I achieved on a diff NF2 mobo before it died...)

    What FSB and multi you using ? (or trying to use ?)
    What voltage ?

    The NF7 series seem to undervolt slightly on the Vcore, so you may need to set it a little higher in the BIOS than to what you have used before, to make it the same in real world.

    right now its at 166FSB 12x multi... not sure on core voltages, I think thats at 1.60 from memory....

    If my reckoning is right, to get 2400 back I need to go to 200fsb, yes?

    Yeah - sounds right.

    I found that i needed to put the RAM voltage higher as well. As my pc2700 ran at pc3200 @ 2.7v in a via333 motherboard. But in the NF7-S it needs 2.8v.

    Up the vcore on cpu and memory but keep an eye on the temps.
    NF7-S often undervolt

    Right then, I'm obviously doing wrong.

    I've set the vcore on the cpu to 1.65 and 2.7 respectively, but the system refuses to boot if I set FSB to anything over 166... even at 167 it won't boot.

    Am I aiming the right way wanting to go to 200 fsb and 12x multiplier? Or should I look at going for a lower FSB and higher multiplier?

    strange thing this Deckard :S

    12 x 200 on my jhuib would need about 1.65-1.7v, put the chipset voltage up perhaps???

    Ok, so I've tried running the cpu voltage at 1.7, the mem at 1.8 and manage to get the FSB up to 169 then it refused to boot.

    Can anyone post what settings they have for their boards? Is anyone running a 200 FSB??? Is it possible????

    aarrrgggghhh!!!

    NF7-S' s tend to undervolt from what is set in BIOS so I would up Vcore a bit more.
    I hope that you meant memory at 2.8 rather than 1.8V

    I used to run a T'bred B XP2400 at 200fsbx11 , currently running a T'bred B XP1700 & an XP2500 at 200fsb on NF7-S V2.0's.

    BUFF, sorry, I meant 2.8....

    What about the other voltages? Do I leave them at standard or up them a bit too?

    And.... should I muck about with the the AGP speed and the CPU FSB/DRAM ratio? At the minute its set to Auto, so I need to change this at all?

    ANd a final question, what should I set the memory timings too? Should I use the BIOS 'Agressive' settings, something else or manually set them myself?

    You do have that stupid cpu interface thing on dont you I fell for that at first and couldn't get jack **** out of my nf7-s its on the cpu screen about 5 down I think needs to be enabled.

    Yeah, I've got the CPU thingy enabled... if I don't it re-boots as a stock 1700XP.

    I just just understand why this isn't working. Even if the cpu voltage and memory voltages are too low it should still boot into BIOS, shouldn't it?

    At the moment, if I set anything over 166 FSB or 13x multi it won't even POST.

    Very odd and a bit annoying...

    Have you tried updating the BIOS? I heard that earlier BIOSs on the NF7-S don't like higher FSBs.
