    Hey TPU Members! I promised everybody on our WCG Crunching team I would post some picks of the lap job for my Q9550. I'm not going to go into great detail, but if anyone is interested in how to lap there process just reply to the thread.

    Tools
    Flat surface - I used a large piece of glass from a coffee table.
    Surface cleaner - I used 91% Alcohol
    Air - I used a portable air Compressor (Canned air just as good)
    Sandpaper - I used 3M Wet or Dry (from Advance automotive)
    Grit sizes (P400, P600, P800, P1000, P1500, P2000)
    Tape - I used electrical tape to hold down the sandpaper.

    Temps before lap job @ Full Load
    [​IMG]

    All the tools together
    [​IMG]

    Just an extra pic of setting up the tools
    [​IMG]

    Stock Q9550 Processor
    [​IMG]

    After 3 rounds of P400 (Remember to clean the processor after each round. Hit it with air then cleaner to not scratch surface.)
    [​IMG]

    3 rounds of P600 you can start to see where the dips where at.
    [​IMG]

    Money shot of P600.. hehehe
    [​IMG]

    I went 4 rounds of P800 (Just enough to see complete copper) It's not set in stone for how many rounds for each grit... You can start to tell when it's time to move on.. It will start feeling like your not doing anything. the processor just glides across the sandpaper.
    [​IMG]

    3 rounds of P1000
    [​IMG]

    4 rounds of P1500. Some people start to wet the sandpaper. I don't.. you don't have to make it look like glass. It just needs to be flat. If you do.. Use Alcohol not water.. It dries faster :p.
    [​IMG]

    Money shot of P1500
    [​IMG]

    And finally 4 rounds of P2000
    [​IMG]

    Another pic of P2000
    [​IMG]

    Temps after Lap Job @ Full Load
    [​IMG]

    Well, I hope everyone enjoyed the pics. Remember, This is not a "how to".. I'm just showing how I lap processors. If anyone wants to lap there processor, and needs more detail. I will be glad to help as much as I can.

    Everyone please help our crunching, and folding teams by joining, and contributing! Thanks! :toast:

    Yea.. when I first started lapping I would go for shine P400 - P2500... but not a big difference in temps.. pretty much the same.. So, I saved myself 4 bucks.. hehehe and a lot of time... hehehe

    but but lapping doesnt help temps, it makes the chip worthless, waaaah.

    no one else was in here whining about how lapping does nothing, so i thought i'd do it for em :p

    nice job, lapping mine made my four cores come closer to each other on my Q6600, but the drop was nowhere near as big as yours.

    Nice work. I think I may lap my e8400. It's sitting @ 57c/57c with a full load on water right now. Thanks for the inspiration.:rockout:

    Man thats freakin beautiful... nothing says "hardcore" like a mirror-polished heat spreader. I worked on my P4's heatsink and spreader for hours but never could quite get that magical point where you can make out objects in the reflection. Too heavy grit would just scar it up more, and too light grit did nothing. Pospc, thats a very nice job too! what exactly is that sitting on top of them?

    "3 rounds"

    Wonder what you mean by that? Surely 3 swipes don't do that :p Think it took me close to 2 hours to lap my old E4300. But I used just 400 & 800 (and a bit of 2000 to make it nicer).

    My E7200 was pretty flat, so I just didn't bother. E4300 had a massive crater on the middle compared to this one.

    Thanks Buck!

    Yea, I enjoyed the temperature drop on my old E8400 after the lap job. The E8400 that I have is a C0 stepping and has one sensor stuck.. but after a few hours of crunching the sensor would free up. My before temps using a zalman 9700n @ 4.05GHz, @ full load were 65c. After the lap job it dropped to 59c with the 9700n, @4.05GHz, @ full load..

    After you lap your processor, clean both the processor and block. Then lay the processor on a paper towel or your hand (something soft) and place the water block on top, and pick up.. It should create a vacuum between the two. It will feel like the block is picking up the processor. Remember, it will not be a complete bond, so the processor will fall. Just remember that you don't have to raise it very high.. just enough to clear the surface (paper towel or hand).

    If the vacuum between the two are weak, I would lap the block. You can always check the block or processor with a razor blade.

    Hopefully this was just a little more inspiration... hehehe


    Hehehe, Your not pitching it the correct way... You need to sell it to a new overclocker.. explain to them that this is a hand sanded processor from an experienced overclocker... hehehe

    Thanks Papahyooie
    That's a thumb screw (Screw driverless) for the case doors.

    When I say 3 rounds, I mean for each round push the processor up the sheet of sandpaper 30 times for each side (4 sides = 1 round). Start, at the bottom push to the top, and back.. that is 1 of 30 times for one side. Clean the processor after each round. Remember, do not ,push down on the processor. let the weight of the processor do the work.

    Thanks CP! :respect::respect:

    The deed is done and I have nice difference. I was only able to take it to 1200 grit. I'm happy with a 3-4 degree drop. Should make a bigger difference when I take it up over 4Ghz.
    3 cheers to Mindweaver for the inspiration!!!

    one is overclocked and the other isnt. i think your OC reset when you took out the CPU.

    Damn, your right. Let me re-clock and post the temps. I knew it was too good to be true:banghead:

    Edit: pics are corrected now. Thanks Phanbuey.

    No wonder it looked so good even without wetsanding :) Yeah, the E4300 was the first CPU I lapped, so I took my time on all sides, but didn't really count the times. Lapping my Thermalright Ultima was a different experience, I'll be happy to lap a CPU after that :D

    But pictures tell more, found them handy, so I'll add couple here.
    400 grit dry

    800 grit wet (and used an old spot as a smoother grit later on)
    [​IMG]
    2400 grit wet for 'polish' (it wasn't a mirror, still had marks on it)

    the only way to really get a true mirror finish is to use brasso after 2500 grit, and then rub it with acetone followed by alcohol to get it off... not worth it IMO. Doesn't improve or hurt temps either way, its just for show.

    after one heatsink mounting it won't be a mirror no more either :laugh:

    EDIT: still nice temps buck :toast: gj man. Basically what I was getting on water (these other f***ers dont live our nice, cool, arid climate).

    Still looks good Buck! Did you use AS5? If so it still should drop 1 or 2 degrees after burn in.

    Looks good Onboard! Nice pics!

    Yea the first processor I lapped was a P4 heater.. hehehe I rubbed on it for 2 days to get a mirror finish.. But your right it's not worth it.. I only take it to p2000 grit now.
