  1. Saw this again and it inspired me to lap my Q6600. I applied the AS5 properly this time as well. At 80+ degrees F ambient temps my load temps at 3.6Ghz(which I couldn't run at previously in this type of heat) are quite good. 52,55,51,54 at 100% load. It's also out of the case and on a tech station with direct fan cooling I should add. Thanks for posting your results.

     

    Sounds like you were met with great success! Glad to read it.


  2. Got bored yesterday, so I ran checked out the power consumption of my X3360 system for crap and giggles with my kill-a-watt.

    Powered Hardware Details:

    Intel X3360 (C1 stepping) @ 8.5x400=3.40 GHz
    266/667 MHz Strap  CPU Vcc=1.12500
    NB Core=1.370	  CPU VTT=1.310
    
    DFI LT P35-TR2 (no modifications)
    
    eVGA 8800 GTSG92 512 meg 
    (770/1,923/2,000 MHz : Core/Shader/Memory)
    
    Corsair Dominator DDR2-1066 (TWIN2X4096-8500C5DF)
    2x 2Gb @ 5-5-5-15 (performance level 6) @ 1,000 MHz (4:5) @ 2.100V
    
    Corsair HX620
    2x HDs (seagates, one a 10th generation and the other an 11th)
    1x DVDROM
    4x120 mm Tricool fans (came with the p182 case) all on low
    1x120 mm S-Flex SFF21F (1600 RPM) on the HS
    1x40 mm silent fan on the NB

     

    That's it... no other hardware (speakers, monitor, etc.) was in the loop.

     

    Kill-a-Watt Readings

    Idle in BIOS screens - 158 W

    Idle in BIOS screens with both HDD's unplugged - 144 W

     

    Idle (with speedstep active in XP x64) - 137 W

    Load (prime95 v25.6 small FFT) - 213 W

    Load (prime95 v25.6 large FFT) - 216 W

    Load (prime95 v25.6 blend) - 210 W

    Playing Crysis - 237-241 W

    x264 encode - 197 W

    Standby - 0 W

     

    No real point to this post beyond just trivial information! It is interesting to me that the large FFTs consistently read 3-4 watts higher than the small ones did which is inline with the software's description of the large FFTs as generating the max heat/power consumption. Here is the similar analysis of my older Q6600-based system, but there are too many changes (MB, settings, video board, memory, etc.) for a "which processor is more power efficient" comparison.

     

    What is little bit crazy is that both systems draw the same while idle, and even @ 3.4 GHz, and faster memory, the X3360-based system uses less wattage on p95.


  3. About 7 months ago I posted data comparing two memory dividers (1:1 and 3:5 @ 333 MHz) on my then Q6600/P965 based system and concluded that for the 67 % increase in memory bandwidth, the marginal gains in actual performance weren't worth the extra voltage/heat.

     

    Since then I've upgraded my hardware to an X3360/P35 setup and wanted to revisit this issue. Again, two dividers were looked at: one pair running 8.5x333=2.83 GHz, and another running @ 8.5x400=3.40 GHz:

     

    333 MHz FSB:

    1:1 a.k.a. PC2-5300 (667 MHz)

    5:8 a.k.a. PC2-8500 (1,067 MHz)

     

    400 MHz FSB:

    1:1 a.k.a. PC2-6400 (800 MHz)

    4:5 a.k.a. PC2-8000 (1,000 MHz)

     

    I figured there would be a much greater difference in the 333 FSB case since the memory bandwidth increased by 60 % vs. 25 % in the 400 MHz FSB case. All other BIOS settings were held constant with the exception of the divider (and the strap) and the given FSB. Subtimings were set to auto and as such could vary as managed by the board which I found out, was required since manually settings some of the subtimings lead to either an incomplete POST, or an unstable system.

     

    The benchmarks were broken down into three categories:

    1) "Real-World" Applications

    2) 3D Games

    3) Synthetic Benchmarks

     

    The following "real-world" apps were chosen: x264, winrar, and the trial version of Photohop CS3. All were run on a freshly installed version of Windows XP Pro x64 SP2 w/ all relevant hotfixes. The 3D games were just Doom3 (an older game) and Crysis (a newer game). Finally, I threw in some synthetic benchmarks consisting of the Winrar self test, Super Pi-mod, and Everest's synthetic memory benchmark. Here is an explanation of the specifics:

  4. right graysky

     

    cpu fsb:800mhz

    multiplier:x10[it is locked at that]

    vcore:1.2v to 1.35 [vcore is the cpu voltage isn't it?]

    ram:1x1gb of adata 800mhz ddr2 1.8v [i have a second module but vista 32bit wont take more than 3.5gb ]and 2x1gb of geil 800mhz ddr2 1.8v both at 5-5-5-18-23

     

    if it is good iam just about [as in - i am holding] to install a freezer 7 pro cpu cooler

     

    thanks

     

    if more information is needed i can add more

     

    Sorry dude, is there a question in there? You 10x multiplier isn't locked... if it's a q6700, it's 10x max, but you can dial it down to 6x if you want.


  5. hi i followed your guide and whenever i overclock my cpu it doesn't start up? :(

     

    it is stuck at 2.00ghz(x2) and that is really annoying seeing as i was hoping to play crysis on it and it wont play. even if i only increase the fsb by 1 it just doesn't turn on, i have increased the fsb on the ram from 800 to 900 and that is fine but the possessor....

     

     

    spec:

    cpu; E4400 @2.00ghz X2

    ram; 600watts

    grafix card; 512mb sapphire x1650pro

    m/b; abit fatal1ty FP-IN9 SLI(C55-MCP51)

    thanks

     

    Can you provide us with some addition info? What multiplier and FSB? What are your vcores set to and what is your memory set to? What kind of memory do you have?


  6. Does it matter what type of motherboard do you have to overcloak? Because the one that i might be getting is a ASUS P5N-SLI and was wondering if it matter what type of motherboard can or cannot be O/C?

    Secondly can you tell me what should i have like the requirements/equipments.

     

    I know that mine would have 3GB ram and a good cooling system anything else?

     

    I dunno about the P5N-SLI, but I would think it'd be fine. There is a short list of of recommended hardware types in the first few paragraphs of the guide. Once you get it put together you'll just have to try and see how far you can push it.


  7. Techarp is hosting a new HD x264 benchmark. Have a look and run it on your system to help populate the data table.

     

    Basically, you run the test encode of an HD sample (1280x720) and it will report back frames-per-second values for your machine @ it's clock/overclock level. You can run it at your stock settings and at your overclock settings to see how your machine compares to others in the database.

     

    My goal is to have a representative set of data for many different chips and chipsets. Please just report your results here in this thread. I will keep the data at that url to keep things simple.

     

    Thanks all and enjoy!

     

    The following image will be updated automatically as new data comes in. It doesn't display any results, but it does show the number of data points collected so far and how they break down by CPU type:

  8. First off, thanks to all who contributed data.

     

    24-Feb-2008 - Finally updated the data tables on the x264 benchmark page. They are now html based (not .gif images) which makes my life updating them much easier and I will keep this tables up-to-date daily as people post results. Have a look at the 'Data Tends' table that contains a look at the Phenom quad vs. both Kentfield and Yorkfield quads. There are also some comparisons of Wolfdale dual vs. Conroe dual, and some other good stuff.


  9. Finally narrowed down my next board purchase to a P5E or a Maximus Formula. My goal is to run a Q9450 or Q9550 (likely the 9450) @ 8x400 or 8x450. Anyway, I've read that the NB/SB temps on these boards can be quite high and wanted to solicit some feedback from you guys.

     

    1) What board do you have?

    2) What is your overclock setting and chip (q6600 running 8x400 for example)?

    3) What is your idle/load motherboard temps (like NB/SB, etc.)?

    4) Optional - what are your board voltage settings?

     

    Thanks all!


  10. If you're running a 45 nm quad on an asus p5k (or any other P35 board for that matter), are you able to hit 8x400 or 8x450 okay? If so, what are your board voltages and mb temps (like north bridge temp or whatever readout that board displays for motherboard temps)?

     

    I ask because I'm thinking about getting a Q9450 next month on this board and since the multiplier is locked @ 8.0, I'll have to jack up the FSB.

     

    Thanks for the feedback all!
