Overclocking an E8400 with an Asus P5Q Standard - I'm confused!

[pilgrim72]

Hi there everyone!

I'm hoping for a little help with overclocking my current system (please see below for current spec). I have had some help from MDD so far, but my BIOS has so many options, I really dont know which ones to change & which to leave alone. I have initially been told to raise the FSB by 5mhz intervals, keep the PCIE at 1:1(?), but there are literally loads of options & most of them are set at AUTO. I also heard somewhere that the AUTO settings are not good when you try & overclock, ad manual settings should e put in for all this stuff. This is a bit much for my little brain, so I was wondering if anyone actually has direct experience of this chip & motherboard, and can let me know what sort of values to put in for everything to get a fairly reliable approx 4ghz clock (i know individual chips, etc vary, so approx would be good enough).

Will anyone need me to list all the options I have on my bios? Also, I have a Hiper530w PSU, overclocking it wont push this PSU too far will it?

Thank you so much for your help - MDD has been very helpful so far, but I am just bewildered by all these options!

You must check that your CPU cooler is up to this first with CPUID Hardware Monitor testing under load, but on the similar Asus P5Q Pro, all you have to do is change the FSB and strap to 400MHz and add maybe 0.1V to the CPU voltage as determined by CPU-Z. Probably 1.3 V will do nicely.

That gets you 3.6 GHz.

This is for a E8500 and is underwatercooling. Also its a very very good CPU but should give you a idea.


Seem to be a few of these about with people clocking their wolfies, so I figured why not make a thread where people can post settings and clocks and trade info.

Here's my effort, was game and general use stable at 1.400V but failed orthos. I'm trying to get it orthos stable....so far so good.

Thats brilliant!

Cheers System7. I'm very cautious with this kind of stuff, and always want to see someone's actual results before playing about with my new, not even two-week-old build!

3.6ghz should be a good starter for me. I've got the programs to test it with from your previous postings.

Thanks!

3.6 should be achievable with any e8400
Something like 9x400 with your RAM running at 1000 (if it can) Would be a sweetspot for bandwidth and speed

that is one epic high FSB for a P5Q, makes me want one more >.<
