    Default Gigabyte x48 dq6, e8500(3.16ghz), pc8500(1066mhz) the 1 with tripple fan. OC to3.9ghz

    Hey!

    I have been reading up and trying to overclock this system now for over a week if not 2 and I have been able to get my cpu(e8500) overclocked up to bus speed: 409 while being stable.

    I am wondering if there is anything else that I can do then to buy a diffrent cpu cooler then my current OCZ Vendetta 2.

    If I increase the cvolt anymore the load temp goes above 74-75C when I run 20/20 results with "Intel burn test". And as far as I know you shouldn't keep running a cpu(e8500) 24/7 at a higher load temp then 74C(I plan to keep it at least a few more years had it for a year).

    My memory got an extra 0.3V so it's 2.1V and running at 5 5 5 15 like it says on Corsairs homepage(also running it 1:1 ratio so if my bus is 400 my memory runs at 800). I will overclock this later but first I wanna max out my cpu like you are suppose to if you gonna overclock your entire system(cpu and memory) and my 4870x2 but that will be a lot later.

    So my question to all of you here is can I change something else to increase my bus speed and still keep the system stable? My idle temp is 43-44C at 409 MHz.

    I was thinking that maybe it's the motherboard that ain't able to run stable at a higher bus speed because rated fsb is 4 times your bus and this motherboard got a max bus of 1600. I am about to try and increase the voltage to FSB Voltage OverControl and (G)MCH OverVoltage Control in the hope that will stabilise a higher fsb(410+) at the same cvolt that I have(409) at a lower fsb.

    Can I use the extra options that I get when I click ctrl f1 in bios to stabilise my system at a higher fsb? and if so how?

    Thanks for any help it's much appreciated by the way if you need any more info just ask and I will probably answer you in 5min or less :)

    Can you link us to your ram or give the model #

    Then give us your full settings and we can try to help you out. There is a link in my signature for BIOS Setting template

    I thought I gave you all the info you needed when I wrote pc8500(1066mhz) the 1 with tripple fan but ok I will check.

    Corsair TWIN2X4096-8500C5DF (http://www.corsair.com/_datasheets/T...6-8500C5DF.pdf)

    Sorry for the late reply!

    Thanks for the memory link as well!

    If your temps are acceptable to you then you can push further, IBT makes things very hot so you may be fine as long as Prime95 or orthos does not get that hot. Keep in mind your system won't ever run that hot anyway.

    It does sound to me like you may want to get a better cooler, since your load temps are up there and you want to push further. Could help with that, and for sure bring your temps down a little.

    You should only need +0.2-0.25 MCH for 4GB with 400-450 FSB, so you can likely bring that down a little bit.

    The rest of your settings look ok to me, but you may need more vcore to push further which may mean you do need a better cooler if your temps are 70's IBT with only 1.35V

    You may also want to set your own tRD (Static tRead Value) to 6-8, and 6 may be too low depending on your ram and FSB. So I would start with 8 until you get your CPU where you want it

    thanks for the reply What exactly is tRD(Static tRead Value) effect and what's the diffrence between 6 7 8?

    I haven't read up on memory OC yet but I will soon.

    tRD is tough to explain, but it is a very important setting. Too tight can cause many issues and or the system to not even start, and too loose can make for very poor performance. 5/6 in your case would be tight and 8/9 would be looser, so that is why I suggested you try a higher value manually set

    Some info on the setting is posted here >>

    Let us know how you get along
