    Motherboard: Gigabyte EP45-UD3R
    CPU: E8400 3.0 GHZ Cache: 6 MB Bus: 1333 MHZ
    CPU Cooler: Asus V60
    Ram: 4GB Dual Channel (2 x Kingstone Hyperx - KHX8500AD2/2G )
    VGA: Nvidia Geforce 8400 GS 256 mb up to 1024MB (256MB Dedicated)
    Power Supply: Asus Power Supply 500W (P-50GA)

    1-I have just assembled this PC however, I don’t have much experience with over clocking, my main problem is that my ram advertised bus speed is 1066Mhz and currently i only get 800Mhz, though i got the ram timing from kingstone website and it says 7-7-7-20 at 1.85v-2.0v , i applied that in bios and it seems that it just ignores my configs and run on its default 800 :S and default ram timings.

    2- Also please post overclocking suggestions for this board with such config.

    3- If i want to raise the Ram bus as much as possible, what do i need to do that, for example shud i lower the fsb for example and raise the multiplier then modify the ratio of (FSB : DRAM) ?

    Please Advice.

    I would start with you reading through a few guides in the Overclocking and Cooling section if you already haven't, Google that board for an idea of what others have achieved, and what they used to get there from settings to bios verisons.

    You should have no issue setting it to 1066, but CL7 is very sloppy...if it's DDR2. I don't have experience with that board, my the P35-DS3L in my G/F's rig was easy to deal with and OC on.

    Really for overclocking you'll want to start with setting your RAM at a lower ratio like 1:1 (i.e. at 333FSB (1333), your ram would be at 667, at 400FSb your ram would be at 800), 400FSB on an e8400 is generally a very easy OC, 1600FSB is an Intel rated FSB for higher end chips, so not too much is needed from voltage adjustment beyond CPUv and memory voltage, though I usually recommend increasing NBv/MCHv by one notch.

    The last few e8400's (C0's) I OC'd to 400FSB, 3.6GHz, took around 1.22-1.27v to be Orthos stable iirc. I know all took less than 1.30v.

    Once you get to your CPU OC goal, then you see what divider will allow you the highest stable operation, be careful though, if you choose something like 1200+ and your ram isn't capable with the voltage and timings provided, you may have to clear your CMOS and start over, so be prepared for that. Like I said do some research, be prepared and you'll be ok.

    Use Memtest to ensure the memory is stable, use Orthos Prime or Prime95 in Small FFT mode for CPU stress test, Blend mode for CPU/RAM/NB stress test. Use Real Temp or Core Temp for CPU temps, and you'll be ok.

    well first ,
    1- how far can i go with my cpu, i mean if i want something that wont kill the lifetime of my cpu,

    2- wat wud be my limit in cpu temperature,(intel says 70*C) but i wonder if that will affect the life time of it sharply

    3- u said that my ram isnt capable with volt and timings provided, well i read on kingston website that my ram can reach 1066 with timings 7-7-7-20
    so how far do u think my ram can go from that.

    4- any hints for overclocking my vga as its the worst thing in my specs ?
