Q6600 and P5Q mobo help

hi
i have just built a new computer

Q6600
Asus p5q mobo
zalman 9700 cooler
antec 900 case

stock was at 266 * 9

OC'd to 333 * 9 (3.0 GHz) with 1.29 volts
ran prime95 for 1 hr and stable
idle at 37 C and load at 45 C

i can also OC to 354 * 9 (3.2 GHz) with 1.34 volts
with also 1hr stable on prime95
idles at around 38 C and loads at 52 C

is it safe to OC to 3.2GHz?
is the temperature too high?
and will the high voltage at 1.34 volts shorten the CPU's life span significantly???

thanks

  1. How about locating your starting voltage to put the over clock voltage into perspective! Run either Real Temp, or Core temp, and look for what it says your VID is.

    Answers, yes, No, and Nope, just watch the temps.

    Most q6600s are good for 3.6 Ghz, so I don't think a minimal over clock would harm anything at all, like you have, so the life span should remain the same.
    Prime stable for an hour, huh? Large or small ffts?

    --Lupi
  2. i dunno what was the VID since the p5q mobo was on AI overclock when i put the CPU in in stock but CPU-Z voltage was at about 1.25 volt

    and also my North Bridge and SOuth brdige are all at 1.30 VOlt are they too high?
    p45 NB and ICH10R SB
    i havent tried testing them with lower voltage yet since i havent got much time to play around with them

    should i lower them?

    and for the prime95 test
    it ran like 3 tests on 1024 and the rest on something significantly bigger

    cant remmeber :P
    my first time Overclocking lol
  3. hehe, niiiice! The VID wont change, so look with Core temp, or real temp. VID is factory starting voltage imprinted by intel when it was tested.

    So list that, please?

    Voltage is kewl, though you prolly can leave SB on auto.

    And that means you used LARGE ffts. That does not test processor stability!

    Small ffts does.

    VID!

    --Lupi
  4. oh no...
    the VID in core temp said my CPU is 1.1625 Volts
  5. LOL, okay, re start, hit the Bios, and under CPU options, disable C1E, Speed step, and then find EIST if it is in there, and disable that too!

    Save and boot, and look again.

    The VID range for a Q6600 is between 1.2000 (the best!) to 1.3250, the worse.

    Almost there! Gonna be high, 1.3000 or higher if its a retail box. So far only one guy in 5 months has gotten a decent VID.

    VID = Factory starting voltage for your chip. IE, at 2.4 Ghz with junk on auto, this chip defaults to that Bios VCore equal to VID.

    VID is also a good indication of OC ability.

    It is set when intel tests the chip, and some pass at a very low voltage, some get high ones, within its range. Its total LUCK, and tough to get then!

  8. holy crap
    VID 1.3250
  9. LOL, told ya, hehehe.

    BUT, thats okay! because it'll still do 3.6 Ghz.

    Do you have Load Line Calibration enabled?

    That is a good first step, because that will defeat Vdrop and droop and allow for better usage of the power applied to VCore.

    All that really matters are the temps. Nice, by the way, the temps.

    You will need a loaded Value of 1.44-1.45 volts while Loaded with Prime small ffts torture test.

    As a matter of fact, go run it for a total of 2 minutes, Small FFT torture test on all cores!

    Tell me your new high temps, hehe, and also watch with CPUz what it says your core voltage is. We want to know the lowest it goes down to.

  10. ::chants in the background.:: Blue screen, Blue screen!

    ;)
  11. clocked to 360 * 9 with 1.44 voltage to be safe

    CPUZ vdroop 1.432
    load temp at 59 degree
    idle at 38 degree

    prime95 test for 2 min at 1024k stable
    should i do it to 400 * 9???
  12. You have to use SMALL ffts! Not Large! The first test will be 8k length! The temps will be higher than Large ffts. Its a useless and misleading setting.

    Blend for RAM, Small ffts for CPU.

    --Lupi
  13. Flame on!
  14. omg it ran up to 67 degrees with small FFTS tests!!!!

    i stopped it after 1 min
    i am entering the unsafe zone arent i??
  15. Naw, its fine.

    Can take some heat, really, so for testing, a bit of heat wont hurt it.

    So go ahead and let it go. We wanna see where it stops at. if it gets to 75c, go ahead and stop it.

    Normally, for a 24/7 OC, you wanna nail 65 c, or a lil bit higher. With added clock speed, and added voltage, the heat becomes a real factor in life span. Keep it low, and all is well.

    Make sure your fan is on 100% for the Zal heat sink.

    You may need to stick with 3.4 Ghz or so with that cooler.

    --Lupi
  16. Personally, I would take it to 3.6 at that voltage and just test with small ffts to get a feel for it, and then decide where I wanna place it. Because in real world stuff, you wont get those temps like you can when you are testing for them!

    if it fails a core, or BSODs, you need a bit more voltage. 1.44 loaded or so.

    Don't let it get over 75c for to long!

    I am soooo tired! I need to sleep. test your temps and stuff and get a feel for em. If you need more help, I will be here tomorrow! And there are alot of people that help!

    You have a board that can nail a high FSB, so 400 won't be anything for it.

    --Lupi
  17. It's a pretty easy test, really, if the temps are over 70c and appear to be heading onward, its not a viable over clock on the cooling.

    If you hit 70c, 71c and its an exceptionally good speed, take it for a gaming run, and encoding.. and what ever your most demanding tasks are for a day with the newest HWMonitor open, it will record the maximum low and high temps, as well as show the current values. Very good for gaming. Open it up, game away, and look after yer done, GPU temps, CPU, and alot of others.

    If you get 60c and lower only, you may think about keeping it there.

    (My testing up to 65c prime nets 52c max when doing daily junk, Vista performance test for its 5.9 or whatever, will git it a bit higher, and thats all.)

    So you pretty much look for the standard, then use common sense on the rest. Until you start down the long and lonely path of VTT, GTL and other signaling modification settings!

    Hehe.

    Night!

    is it safe to clock at 354FSB with 9x multiplier without seriously shortenning the lifespan?
    go higher?
    354 too high?

    :lol: :lol: :lol:

    As long as you keep the temps under control, you should have no problems with the lifespan of the CPU.

    Make sure the fan on your Zalman cooler is at 100% and give it some more voltage. As Lupi stated, as long as you can keep it under 75c you are in the green. These chips can take more voltage than most people think. Saw a thread a while back where someone wrote Intel and got a statement that the C2 65nm series was designed to handle 1.5V. I have a Q6600, same VID that is stable @ 3.6Ghz but only with 1.55V. Not much of a problem for me as I have it on watter but you may have some troubles with your temps.
  23. wow
    1.55 volts!!?
    thats crazy
    on watter means water cooling right?

    now
    is the longevity of the CPU dependent more on the amount of Voltage or more on the temperature it idles and loads on?

    would it be okay if i manage to clock to 3.6 GHz but with like ~73C Load temp?

    im not a total freak aboutlosing a couple of years of life span of my CPU
    i dun care if my CPU lasts 10 years or 5 years since im probably gonna sell it in a year
    but i certainly dun want it to die in a year or two :P
  24. Yup, 1.55V. I have seen other posters using 1.6V+ on their 65nm Core 2 CPU's in order to obtain their desired Oc. The generally accepted max voltage for the 65nm generation on air is 1.5V. You can go higher but you will probably need better cooling to keep up with all the extra heat. Yes, my system is wattercooled. @ 3.6Ghz w/ 1.55V, I am around 65c with my hottest core in a torture test. Under real life usage, it rarely goes over 55c.

    The longevity of the CPU is really dependent on all of those when taken to the extreme. Higher voltage causes higher heat and electron migration. High temps and high deltas between idle and load temps puts extra stress on the entire package. With this all in mind, running a high overclock will lower the lifespan of your CPU. Probably from 10 years at stock to 4 or 5 years overclocked. They will rarely fail before it is time to upgrade as long as you keep them within their thermal specs (max 75c would be recommended).

    If you are 100% stable at 3.6Ghz and your CPU only loads to 73c with stress testing, you will be just fine. Stress testing your CPU puts an artificially high load on your system (unless you are in the professional sector where you would not be overclocking) and, as such, represents your worst case temps. In day to day operation, I would expect it to max out in the mid to upper 60's.
  25. man thats still gonna be some hardcore stuff hahaha

    now i get why ppl risk water cooling or lapping to reduce temperature
    :P

    but overclocking is such an art
    before i was struggling to run 333 * 9 with 1.28v
    and now
    thanks to Lupi
    all i did was turn on Line in Calibration
    and its giving me no problem for 2 min running 354 * 9 with 1.28v
  26. My Q6600 must be very similar to yours.
    100% prime95 stable @ 3.0ghz with only 1.285V.
    Same VID to.
    Never tried for any intermediate Oc's, went straight from 2.4 => 3.0 => 3.6.

    Not so much of a risk with wattercooling.
    Just make sure to test the loop overnight before you install any of your components.
    Lapping, on the other hand, can get a little harry.
    Not a real hard procedure but some people still manage to damage their chips in the process.
    Still, it is an easy way to gain 2-4c on your temps...

    If you want to keep this system stable for as long as possible...
    Find what settings net you a stable 3.6Ghz and, as long as the temps are fine, save it as an Oc profile in your BIOS. Leave it at 3.x Ghz, stock voltage, until you feel like playing a game. Reboot and switch on the Oc. Works like a charm!

    made some more tests and these were my experiments
    pretty sure im gonna let it run at 354 * 9 (3.18GHz) at 1.28v
    can you suggest me a good voltage for the North Bridge and the South bridge??
    :P

    If you are not going over 400Mhz FSB, I would leave it on auto.
    ASUS' BIOS has settings pre-programed up to that point.

    Not a bad overclock.
    If you want to keep it in that area, I have a further recommendation. Change it to 400 * 8 and put the RAM at a 1:1 ratio.

    Even with DDR2 1066, you will have better performance running 1:1 with lowered timings. Reason being the RAM has to use your FSB to shuffle data around. Even if it is trying to push data through at 533Mhz (it is DDR RAM so it is actually 1/2 the listed speed), you will still be pushing it through at 266Mhz, 333Mhz, 354Mhz or what ever you have your FSB set at. If you can push it through at the buses maximum rate with lower latency, you will obtain your optimal performance.
  29. i think the multiplier on my q6600 is locked to 9 though
    do you know how to change it?
  30. It is unlocked from x6, to x9.

    There are two areas to change it, AI tweaker/ Ratio setting, And then under advanced CPU settings has the other one. Change them both to your desired Multiplier!
