    Default 16x200 or 20x160... Any difference?

    So since I'm so new to this stuff, I was wondering if there were pros/cons to the two settings on the BCLK and Clock Ratio to get to OC my I7 920 a little up to 3.2. I'm set at 16x200 now, running DDR3 1600 mem, so the mem multiplier works out at 8 and my Uncore is set to 17. Without getting into all my other settings (which I must thank Mr. LSD for), is there a difference in these two settings to get the same numbers?

    It would be better to use higher Bclk I believe and you would have a higher uncore due to that, but it may be better for you to use the other way around, have you tested both or were you just wondering?

    Thanks L...

    I haven't tested it, because it's for my studio DAW and basically I'd like to "set it and forget it". I'm not much into the tweaking end, and I wouldn't really know how to test it anyway. I was just curious if one setting creates a more optimal situation with the other BIOS parameters.

    You answered another of my posts regarding the highest I could OC with the stock fan, which was about 3 or 3.2. If I did want to play it safe and just go to 3 (or best closest number), would it be too much to ask to have you post your template with the correct settings? Thanks very much!

    Thank you so very much! My only question about you template is in regard to VCore, where you say "may need 1.25-1.32 or so". How do I know if I need it or not? I know, dumb questions probably, but I am on the old learning curve and I very much appreciate your patience.

    Thanks!

    Well you can try and set stock amount, if it fails to boot then you know that wont work and you will need to manually set more.

    If it boots though, same as if you have to try more like in the ranges I suggested, once in windows you will need to do stability testing with Orthos, Prime95, HCI Memtest, IBT, Linx, Ect to unsure you are stable.

    You can get all of those and many more here >>

    Well I gave it a shot, and after about 30 seconds of Prime95 she shut down with a BSOD. Didn't get the code, but I was watching the temps of the 4 cores and they were hitting 70C pretty fast before shut down. I think I'll give this experiment a rest until I get a better cooler.

    Sorry its a bit off topic, but are you using a firewire interface? If so, have you had any issues with the onboard FW controller?
    I know its a TI chipset so should be all good, but being onboard, makes me unsure. Reason I ask is I'm having a few issues with my FW interface in win7 x64 and not sure if its due to crappy win7 drivers or the onboard FW solution.

    Ya, likely Vcore was not enough and since your temps were shooting up there you may need to wait for a better cooler.

    @R3alsp33dy0ne

    If you are unsure if it is the win7 drivers or not, you could easily setup a dual vista or XP boot and test there. Do you need help doing something like that maybe?
