    @ Angel Marinov ,

    Hello,

    You are the very best of all the C90S's users.
    You are making the job that ASUS should have done by themself.
    Thanks alot, really thanks.

    This Easter weekend I'm taking my son to a LAN party. With his team they play "Battlefield Bad Company 2".
    So I have no time to study all your file before next week, and I am very impatient.

    I hope you find some free time, or even a few days off because you really worked hard.

    I wish you a good Easter weekend.
    Alain

    Hello, great job but I've got a question. Why did you use G.SKILL 800 MHz? I think that C90S chipset can't get over 667 MHz, right?

    First, i must thank you for your tutorial. It's a "state of art". The very best indeed, There's a lot of dedication and love in it.

    Hope i can contribute with something for the well beeing of all C90S users.
    I´m working on a simple and efective way to build a thermal controll of the 4 fans all toghether. What do you think?

    By the way, clarify me...Will the E6500 (45nm) work with the 1002a bios?
    Must i change the power supply? Mine is 120Watts max. output.

    Regards,

    Hi,

    @ Angel Marinov

    a) A year ago, I bought some high performance RAM from Kingston : "667MHz DDR2 Low-Latency CL4 (4-4-4-12)" .
    But it has been impossible to get them working at CAS 4, with ram frequency synchronized to fsb.
    I even tried to modify the SPD program with no result.
    Then I found that the C90S cannot use CAS 4, but unfortunately I forgot the link.

    But it is possible to tweak the other timings, but CAS.
    Just go and see MemSet.
    So from 5-5-5-15 you can get 5-4-3-12 very easily.
    It's better, is it ?

    I've no test nor review to show, but everyone can play them by themselves easily.

    b) @ Angel Marinov and Bigbrain
    E6500 and E7500 looks like to be almost the same ones.
    So I think a E6500 should work with bios 1002A.

    Hey Angel,

    First off, great thread! cheers for putting this info together and online.

    This Saturday just gone my c90s wouldn't boot, from reading other posts it sounds like the graphics card fault has just kicked in after over 2 years of solid use. So now I'm trying to follow your thread and have a couple of questions.

    1. None of the images or links to documents seem to be working, do you know if there are any hosting problems with these and when they will be back online?

    2. Correct me if I'm wrong, the North bridge is directly under the GPU and the south bridge is under the big aluminium heat sink on the other side of the ram from the GPU right?

    3. Is there any gas/fluid inside those copper heat pipes? looks like a neat place for a phase change system.

    FYI, I'm trying to find a source MXM II ATI cards approx HD 4650/4670 DDR3, I'll post up where to source if I do find them but if anyone else knows where to get them let me know.

    Cheers,
    DieselMonkey

    Hi,

    Just have a look here ? Or here ? I've searched for "ATI HD 4650/4670".
    But it costs a bit much money, is it ?

    edit : Now I wonder if they are reallly DDR3, even if the seller claims they are. :confused:

    Thanks guys,

    I've found another supplier, pretty much the same price as the one 9800xpv posted. Its also a Toshiba bios. I've asked the supplier if they know it will work in a C90s but do either of you know if a Toshiba bios ATI card will play nice with my C90s?

    Cheers,
    DieselMonkey

    Hi,

    Overclocking the C90S with TurboGear is limited to about 2.93GHz, so you can't use TG with the E7500 which is already at 2.93 to go to an higher frequency.
    If you want to go to 3.0 or 3.2GHz you may use ClockGen, or SetFsb, or others. ClockGen is very easy to use with the C90S.


    So the E7500 has the highest integer multiplier, the E7600 has 11.5 and it will work like a E7500 with 11.

    Amazing work Angel. I've been holding off doing major modifications to my c90s specifically for this guide. Mostly due to the need for creating a custom heatsink for the GPU.

    That ever-wonderful 8600m GT of mine breaks all too commonly, and requires the oven fix when it cools down too quickly.

    If you have any experience in .torrent files, feel free to create one with the guide & resources, and I'll happily help seed. This will hopefully help out the traffic I'm sure your site will be inundated with.


    Keep up the fantastic work, most likely I'll be trying to find a CNC place around my home town to create the custom heatsink. You mentioned the need for heat pads, do you think it would be possible to modify the copper to not need the heat pads and instead use thermal paste?
