    NF7-S (v2.0) north bridge voltage

    Hi.

    I have been trying to overclock my system (see sig) a bit more. It wont run at 200fsb. THis could be down to the RAM (pc2700.) but i recently noticed that the nb cant have any more volts throught it than 1.7v. This is the default.

    If i could put this to 1.8 would it allow me to get higher fsb, or not?

    Will

    Personally I'd try relaxing the RAM timings if you're looking to push up the FSB further before increasing the chipset voltage...afaik the chipset should go much higher than 200 FSB on stock voltage anyway - it is, after all, rated to work at 200FSB.

    Absolutely. PC2700 is not designed to run at 400mhz but only at 333mhz, with slow (high) timings and a lot of luck you may get 400mhz out of it (esp with extra RAM voltage). The NF7-S v2.0 is based on the 'Ultra 400' nVidia nForce2 chipset and is designed for 400FSB with many doing 450FSB+ where RAM and CPU aren't limiting them. The original nForce2 only officially had 333FSB with 400FSB being a possibility. They used 1.5v for the chipset voltage and could often hit 400FSB, most 'Ultra 400' use 1.6v and that should be plenty for 400FSB+. You should consider that cooling and CPU aren't limiting your o/c because it's pretty certain it's your PC2700 RAM.

    rev2 also has the crap niosy nb fan, which might be partly the reson it goes higher.. my rev1.1 is fine upto 440fsb. one of my pc2700 sticks can only do 410 on 2.78v but another does 440 at default volts, and my pc3200 stick does 440 too also on defualt volts, 440 being the mobos limit i cant test the ram further.. but if i get time i will have them.

    iirc 1.7 is set as default with all recent bios versions, i remember 1.5 being default when i got mine though

    I doubt in real world usage it would be worth it really. Even 333FSB and Dual Channel PC2700 is very powerful and I doubt it will hold your 2.2ghz TbredB back much more than the odd 1-2%. I bet you can still get pretty close to 400FSB by o/c'ing the RAM, right? If so then I'd certainly say the gains of switching to PC3200 would be small. Consider how much it will cost you, you should still get decent money for your current PC2700 but it may not be worth it for the odd few percent.

    Bah shhhh austin, Memory bandwidth is worth it, it makes everything faster. Its not like we are talking thousands either, £50 for some nice pc3200 stuffs is well worth the effort.

    And when you sell your old RAM, and put the cost against the new one, its going to be a lot less

    Memory Bandwidth is underrated here - its a god send for Encoding and 3D rendering. It makes a noticeable difference

    Well im meant to be saving for a summer holiday, so i cant really spend lots of money on something i dont *really* need. Just have to get new RAM next time i do lots of upgrading.

    Sounds like the best idea.
