    Q6600 OC 3.6 9x400 DDR2 400MHz 4-4-4-12

    Hello again,

    I'm wondering if anyone with experience could offer some advice.

    I just overclocked my Q6600 to 3.6 using 9x400 multiplier... I set my RAM to 800Mhz in BIOS (see image below)...

    http://img824.imageshack.us/img824/1...ckquestion.jpg

    Is this a safe setting? I've run prime for 10 hours before with no problems but I just want to verify from more knowledgeable people.

    CPUz says DRAM Frequency is 400mhz but because it is DDR2 then it is actually 800MHz (as per the BIOS setting) correct? So it isn't going below 500mhz like it would appear, which would be bad, right?

    And 1:1 FSBRAM is ideal?

    4-4-4-12 is safe as well?

    I don't want to damage my RAM or CPU or anything... I boosted my NB voltage by .1 something, only 2 notches up inside my Asus Maximus II Formula BIOS, and I'm running my Core Voltage at 1.39 in BIOS (it appears 1.384V in CPUz)

    Any advice is appreciated, thanks

    If your ram is rated at 4-4-4-12 and is only running at 800mhz then it should be fine.

    I presume your FSB is at 400 or whatever its called on 775s. Stock is 200 so its effectively doubled?

    I would check on the voltages and temps based on intel recommended and other posters

    Yeah the Q6600 is rated at 1.5v, so my 1.38~ is really good, not the best, but many people can't even get their's to 3.6ghz so I'm happy.

    I just don't know much about this sort of stuff, overclocking in general, just a little bit... especially I don't know much about RAM which is why I wonder about my timings and clock in general.

    Re: Q6600 OC 3.6 9x400 DDR2 400MHz 4-4-4-12

    My Q6600 is running at 450 x 8 (3.6 Ghz) and has been for around the last year now with no issues at all.

    It seems that you have to be lucky to get a Q6600 which can run faster than this. I've had mine at 4 Ghz steady for a while in the past, but ended up ramping back on the OC as my usage didn't warrant the need for speed and power!

    Stock speeds on the Q6600 are 266 Mhz as this then makes the CPU have the standard 1066 Mhz FSB. Most Q6600 I've been near have been able to run at 333 Mhz with no problems at all and a few struggled with 400 Mhz or higher.

    What would you recommend my OC be for gaming? I chose 4-4-4-12 because I heard it is capable for my memory and I thought it would make things load faster...

    Is OC my CPU at all necessary for just playing games alone? I don't think the CPU would bottleneck them actually so probably stock Q6600 will run the same as 3.6ghz with 0% difference right? Or am I gaining any performance boost that I cannot directly see?

    It's hard to see the difference tbh between factory and 3.6 for me... I feel like things boot faster and load quicker, but that may just be my imagination...

    What's the difference between 3.6 at 400x9 and 3.6 at 450x8? And how will running my ram at 800Mhz @ 4-4-4-12 benefit me over the factory defaults?

    At factory default, my FSB:.DRAM ratio is 1:2, it's better to be 1:1 is it not?

    Sorry for my ignorance, I have in fact read a lot of forums but I still haven't quite grasped it yet.

    edit: Also is it normal for there to be warm air blowing out from my fans under load? The PSU seems to be a little hot, unfortunately it is right above my CPU fan, I think it contributes to my cpu temps. Any way to reduce heat?

    Sorry for all of the questions, I hope that I can clear up some of my misconceptions in this thread

    Bigger overclock = more power & heat.

    For gaming CPU limiting is extremely rare, especially at higher resolutions. I've dialled mine back to just 3ghz because in all honesty I didn't see the point of running it higher (despite being on water). I don't think that's changed and my bottleneck remains my GPU, not my CPU.

    Good overclock though What you stick with is up to you - it's always a balancing act - and just remember that in the summer your temps will climb as ambient temperature does..

    What settings do you use to achieve your 3.0?

    375x8 or? How can you get 1:1 fsb ratio with your DRAM this way? What DRAM Mhz is set in BIOS?

    And can you verify whether 4-4-4-12 is a worthy improvement for my RAM?

    Thanks

    PS

    My cpu seems to bottleneck too, if I try to max all settings in Battlefield Bad Company 2 then I run into a lot of video lag, input delay... it is impossible to play like that, with PhysX and AA/AF, etc...

    I tend to have to keep AA/AF very low or off and it still is too sluggish for my tastes. I don't like any delay stopping my score

    I tried overclocking my GPU to see if it would help, I didn't notice any improvement...

    I just dropped down to 3.2ghz @ 1.28 vcore, 400x8 for a 1:1 DRAM ratio @ 800Mhz

    Ironically, I don't know how exactly, but I just played Battlefield Bad Company 2 again at max settings, full 16xQ/16 AA/AF settings and it was running smoother than before when it was at medium settings... Very strange, computers baffle me at times...

    Now if only I can figure a way to lower my GPU temperatures (it runs at near 70c under load)

    ------ note ---

    I think at 3.6ghz everything was running too hot, perhaps, although it wasn't really apparently hot...

    But at 3.2ghz with low vcore, it is just amazing... I notice everything from bootup to gameplay, loads so much faster and is very smooth.

    70C is fine for a GTX285 under load, don't worry about that.

    By running with a higher FSB and lower multiplyer, you should in theory get better performance per clock cycle (i.e. even through the 3.6GHz remains) on account of the processor interacting quicker with the RAM.

    Rob... keep it at the slightly lower speed bud.. lets face it, it's hardly a sloiuch is it?

    Besides, my Quad at 3.2 is jerkier than it is at 2.9 ish, and I think the cpu throttles itself rather than crash at the higher speed. Mine's a QX, which is notoriusly hot and a bad overclocker, so if you got a good Q6600 and if its happy at 3.2 ish, let it fly there......

    Okay, thanks for that explanation

    Agreed. I'm sticking with 3.2, my entire computer right now is running better and faster and smoother than when I first built it over a year ago. I'm really amazed, I'm also a bit annoyed that I didn't achieve this at the beginning! I must've installed something wrong each time and messed with it because my performance was crap. But now it is unbelievably fast, and quiet too!

    Now I'm just making a few minor fixes after I did a complete defrag and virus scan... I'm going to make a complete backup on my ext-hdd so I never lose this heh.

    I'm working on "why my GPU is playing games perfectly at max settings with RivaTuner installed" but when I uninstalled rivaTuner then the performance dropped completely from like 100% to 25%. I want to know what RivaTuner is doing to make such a huge impact.

    The faster FSB helped when my PC was used as a media hub streaming and transcoding files to be sent around the house to various devices. I've now moved, had a little daughter so it's usage has changed a LOT over the last 12 months.

    I also set it as that just to annoy a friend who though his xeon with a 1600 FSB was the dogs danglies and it's just never been switched back to lower speeds as it seems to be happy running 24/7 at this speed with speedstep and all that gubbins disabled. It also looks like the DFI motherboard I have with its plethora of BIOS options to play with was a good choice as well

    1600 fsb? Is that even possible? I thought I read that 400 is like pushing the limit on most cpus?

    Re: Q6600 OC 3.6 9x400 DDR2 400MHz 4-4-4-12

    the FSB limit is generally imposed by the motherboard, not the CPU - if you set the CPU multiplier to x1 (that's probably not possible, but it's an illustration ) then as far as the CPU would be concerned it would only be running at 450MHz. CPUs tend to be constrained by a highest maximum frequency, rather than a highest "FSB". Motherboards (or their chipsets, to be a little more price) generate the FSB, and thus are a more likely candidate for limiting the FSB. Don't forget that a number of top end Intel CPUs shipped with a default FSB of 1600MHz (i.e. 400x4), so the chipsets that support those must be able to run at a stable 400MHz 24/7, meaning they're likely to have some overhead beyond that for overclocking.

Don't forget that a number of top end Intel CPUs shipped with a default FSB of 1600MHz (i.e. 400x4), so the chipsets that support those must be able to run at a stable 400MHz 24/7, meaning they're likely to have some overhead beyond that for overclocking.
    Ah, okay. I learn little by little

    Thanks for that.

    I don't think I'll be messing with any cpu overclocking on this computer again, it's running great as it is at 3.2ghz, but in the future when I get a new rig then I will look into what you're saying to see how much I can get out of my FSB.

    Some guy who works for eVGA has a 4.8ghz cpu with 30x160 or something to that effect.... his rig looks monster....
