    Default Overclocking Help Q8400 and EP45T-UD3P

    Hi guys, I am new to the forum and to overclocking also. This motherboard has so many tweak options on it I don't know where to start. As you can see from below I have C.I.A. 2 turned on and running the Racing profile, which from where I ran prime95 for an hour the other night and everything was stable. Temps never got above 165F (ambient room temp about 70F), CPU was running at 3.07GHz, bus was 384 and FSB was 1536. The memory was running at 768.4MHz and no problems whatsoever.

    But then I switch from Racing mode to Turbo and the computer will boot fine, but then locks up on the windows logo screen, I have a feeling that it may be my memory frequency running too high but not sure how to resolve the issue. I have also tried disabling cia2 and manually setting the host clock control and it keeps increasing the memory speed also, and at the same time cpuz shows the timings change when the bus speed is increased and I think this is because of the auto timing setup.

    I'm not looking to get the fastest possible out of it, I want it to run stable but faster than stock. I also noticed that when I disabled CIA2 and CPU EIST function my multiplier kept changing in cpuz like the stepping was still activated as it would not hold a constant frequency (at idle), any ideas? I have included the current bios settings I have below for your information. Please let me know what you guys would recommend for overclocking this beast or atleast a starting point and whatever other information you need, I would greatly appreciate it, thanks!

    P.S. I also have not used optimized defaults in the bios either and I am using a stock heatsink, a possible upgrade in the future, fyi

    If you want to overclock you need to do it in the BIOS and Disable CIA2, EIST, and C1E

    What speed do you want to run and I will advise you back some settings to try and get you started

    Thanks for the reply, I can easily disable those in the bios, and the speed may be around 3.2-3.5GHz, as I said before I have a stock heatsink and fan but I thought about upgrading to an Artic Cooler. I'm just not sure where to begin, especially when it comes to setting voltages and timings on the memory, I greatly appreciate your help.

    Ok Lsdmeasap, I have tweaked it as shown below and so far so good, and I can definitely tell a difference in speed of opening programs but I have not stressed tested it yet. I took your suggestions and also the ones from here http://forums.tweaktown.com/295784-post5.html
    Anything else you see that can be easily tweaked to increase performance?, and also would increasing the PCI Express Freq make an increase on how your video card performs? Thanks again

    Can you give me a link to your ram, or the model #?

    Also please post a screenshot of Memset so I can see what all those Autos you are using for memory are really set to
    Tweakers.fr

    PCI Freq would be best at 100, more can hurt your hardware really and I would not advise it unless for short periods when benchmarking or something. Then you could use 105-110 but be careful
