    OC Help! Rookie here, help OC'ing a D975XBX2/Q6600/800 DDR2

    Wow,as long as I have been doing computers, I never really wanted or had the need to over clock. But you guys are gettting to me...so are the limitations to HW and their compatibility.

    I am looking to OC my PC, to bring the Proc speed to a nice and balmy 3.0 GHZ, with a matching FSB to the Ram and Proc as well.
    I would like to see a FSB of 1066 (native to the proc) on the Ram as well.

    The specs are all in the sig, any recomendations?

    Edit: Any one know what my 1800 GTO's will see out of this...little or no effect, faster PCI bus...(I really dont want to overclock the PCI bus)?

    Hi raceghost, check the stickies to get some back ground. When you've tried some stuff and need some help post back.

    The limitation may be the motherboard as I don't know what sort of o/c settings it has. And the odds you'll get the RAM to run at 1066 are best described as "very slim"!

    Sounds like I am better off with 8Gigs of 667/675...?'

    You don't need new RAM, you just need to understand that it's unlikely to go much faster than about 900MHz. And don't worry about running CPU and RAM in sync either: despite the old wives tales I see about, it has no effect on performance.

    Re: OC Help! Rookie here, help OC'ing a D975XBX2/Q6600/800 DDR2

    Cool. I was only curious to the RAM for a better base on the multiplier and frequency. Good looking out. Though I still haven't the slightest clue what I am doing. I am having toruble making sence of the math. I even try setting other forums suggest, and I am not even seeing the same claims. I realized though, that what i am finding is just tidbits, I will read and read, and never find the entire settings, so I know I am missing something.

    I need a full settings, with instructions on exactly which ones to change, and to what... Hoping to find someone who posts up.

    Most all though, I must say, have been or were OC'd with 667 DDR2.

    Re: OC Help! Rookie here, help OC'ing a D975XBX2/Q6600/800 DDR2

    First, I would lower your memory divider so that is not an issue with you overclocking your CPU.

    Next, set the voltage of the cpu to somewhere around 1.3v ish. Whatever it runs at at stock. Next raise the FSB in 10 or 20 Mhz increments until crashing or other instability. Get the new Prime95 off of google to stress all of your cores. Also, keep in mind your temps.

    Now some math! The FSB on your motherboard bios is probably shown in QDR. Basically, you take that number and divide it by 4. Then multiply that by your cpu multilpier and you will get the speed of the cpu. Example: your q6600 has a FSB QDR of 1066Mhz so divide that by 4 = 266.5 and then x 9 (which is the highest multiplier of your q6600) = 2398.5 (2.4GHz).

    If you want to just reach 3.0 then you need an FSB QDR of 1333MHz ((3000/9)*4). There is the math.

    If your system hangs along the way to 3.0 then you will most likely have to raise the cpu vcore and maybe the northbridge voltage too.

    Make sure you tweak one setting at a time so it is easier to trouble shoot.

    Hope this helps and good luck.

    My feeling is that this guide is useful, if a bit overcomplicated.

    Re: OC Help! Rookie here, help OC'ing a D975XBX2/Q6600/800 DDR2

    Totaly abliged for the reading liturature you guys found me. Unfotunatly, my timings are giving me trouble. I read through that, and understand that, though I may not b e getting the memory portion. I see the fsb jump to 1333 on mine when i see a 3.0 Ghz proc speed. Either way, my system wont post. I have to pop the battery to reset the bios, to get it out of that. That is why i was concidering moving back down to some OCz stuff i found that looks narly, and is approved by ati for my x1800's. But its really cheap and I believe will dissappear, if I need it, and dont get it soon. So what is your take. Seen any settings for my system with 800 or 667?

    You need to look very close at the ram. Get memtest and test the crap out of the ram. Find where it tops out at. Then bring the cpu into play.

    Ram aside and given you have better than ave cpu cooling. 3 ghz should be a cake walk with the quad and badaxe.

    I haven't done any personal research with the Intel Quads, but I know that some of the Dual Core steppings are pretty responsive to undervolting. If you aren't ever really stressing all four cores at any one time, you might try looking up some basics on undervolting as times hitting those high frequencies is more a simple heat issue than a hardware compatibility issue (the "rams not good enough" excuse).

    FIrst i have a question then i have a statement. Do you know what steeping your Q6600 is? B3 or G0? That will affect a lot of things. I have the G0 stepping at 3.2GHz on 1.38 vcore. So you can start with your vcore at this point and decrease it everytime it POST's until it wont post, then you raise the voltage to the lowest voltage which it did post at. One last thing Overclocking a CPU will do more than overclocking your memory. Just keep that in mind, and 800MHz ram is good, no reason you need to change that.
