  1. It'll only make a difference if you want to use a ratio that's NOT 1:1... in that case, you'll probably want RAM that's faster than 800.
  2. Okay guys, I updated the guide (now version v1.2). It has been streamlined, dead/bad links removed, etc.
  3. Topic says it all. I'm only interested in your vcore @ 9x333 if you own a g0 Q6600 and you minimized the vcore and if it's stable to 2x orthos or prime95 v25.3 for over say 4 hours. It would also be cool to see your VID as reported in coretemp. So I guess I'd like to see two things: 1) Your minimized vcore @ 9x333 (g0 q6600) 2) A screenshot of Coretemp under load to see your VID and temps Thanks in advance!

    Q6600 owners... what is your VID?

    Updated the first post of the thread with the data collected (123 replies now) and added some histograms and basic statics to help visualize the data set.

    lapped my Q6600 (pics and results)

    I just edited/updated the first post of the thread with a few more pics and a brief description of how I lapped the chip for anyone interested.

    Q6600 owners... what is your VID?

    I don't quite know what to make of this whole lower VID = higher o/c potential thing. My chip for example, is a B3 stepping Q6600 w/ a reported VID of 1.2875V (coretemp), yet I can run 9x266 (stock) which is stable to 2x orthos for over 8 hours (I stopped it after 8 hours) @ 1.1375V in the BIOS which is 1.040V in CPU-Z under load. I can also run 9x327 @ 1.2275V in the BIOS or 1.208V in CPU-Z under load or a full 9x333 @ 1.2625V in the BIOS or 1.232 V in CPU-Z. My point is that all these vcore values are under the VID reported in coretemp. In my case, the VID reported in coretemp doesn't seem to mean anything given that I can run my system up to a 25 % o/c well under this voltage. Questions: -What does the coretemp VID mean if anything? -When comparing two identical stepping chips, does the one with the lower VID equate to anything meaningful?

    First OCCT Run E6850

    Does core temp work on your machine? It's pretty good and I'm *really* curious what your temps are under a full load @ 9x445...
  11. I put an NF5 on my old 6800 GT when the stock fan burnt out. It's very quiet and does a great job cooling the card. I dunno if they still sell them or not.
  12. I just read the FSB1333 Intel Processors & New 2007 CPU Charts article over at TH.com and am happy to see that the testers over there have drawn the same conclusion that I have about fixed final core speeds with higher and higher FSB speeds: faster FSB speeds w/ a C2Q/C2D don't equate to faster real-world benchmarks. Have a look at page 8 from their article comparing the "old" 1066 MHz FSB to the "new" 1333 MHz FSB chips: average gain <1 %.
  13. What is a better overclock? Good question. Most people believe that a higher FSB and lower multiplier are better since this maximizes the bandwidth on the FSB. Or is a low bus rate and higher multiplier better? Or is there no difference? I looked at three different settings on my Q6600: 9x333 = 3.0 GHz (DRAM was 667 MHz) 8x375 = 3.0 GHz (DRAM was 750 MHz) 7x428 = 3.0 GHz (DRAM was 856 MHz) The DRAM:CPU ratio was 1:1 for each test and the voltage and timings were held constant; voltage was 2.25V and timings were 4-4-4-12-4-20-10-10-10-11. After the same experiments, at each of these settings, I concluded that there is no difference for real world applications. If you use a synthetic benchmark, like Sandra, you will see faster memory reads/writes, etc. with the higher FSB values -- so what. These high FSB settings are great if all you do with your machine is run synthetic benchmarks. But the higher FSB values come at the cost of higher voltages for the board which equate to higher temps. I think that FSB bandwidth is simply not the bottle neck in a modern system... at least when starting at 333. Perhaps you would see a difference if starting slower. In other words, a 333 MHz FSB quad pumped to 1333 MHz is more than sufficient for today
  14. Great job judging by those pics. Here's my thread lapping the IHS on my Q6600 with pics and before/after results.
  15. I used an 8x10 piece of glass intended for picture frames I got at home depot. I think it was 5/32" thick (about 4 mm). @oneshot: I wouldn't keep that towel under the glass when you lap; tap it down to a flat surface. I used the counter in my bathroom, but any flat workbench will be fine.
  16. Also plan to stop by an auto parts store... doubtful that you'll find any wet/dry over 600-800 grit at HD. I got my 800 and 1000 at an auto parts store.
  17. Too heavy dude... you'll have a hell of a time getting rid of it. I'd either use low odor kerosene or that soap/water mix. I didn't do circles with mine at all thinking uneven pressure would ruin it. I also did the whole thing wet; it lubricates as well as catches metal particles/dust you don't want in your hardware or in your lungs. The Zalman 9500 is mirror finished??? Hmmm... that may imply that it's flat but your idea to use a marker "X" and 1600 grit is a good one. As to grip, just do what gives you the most control over it. Don't let it bounce or jump as you move it across the sandpaper.
  18. Here is a short list of programs that actually use all 4 cores of a quad core chip. If you know of others, please post them to this thread, and I'll update it. THE LIST: Real-World Applications 3D Studio MAX using Mental Ray Renderer (>99 % of 4 cores) Adobe Premiere Elements v3.0.2 (52-85 % of 4 cores depending on source type, filters, etc.) AutoGK v2.40 (30-53 % of 4 cores depending on source type, filters, etc.) Cinema 4d Rendering (>99 % of 4 cores) Dr. DivX v2.0.0 (47-65 % of 4 cores depending on source type, filters, etc.) DVDShrink v3.2 (~90 % of 4 cores) Lightwave 3D (>99 % of 4 cores) Nero Suite 7.x (>90 % of 4 cores when encoding) Noise Ninja v2.13 (~80 % of 4 cores when doing the noise reduction on an image) Sony Vegas 7.0e (83-100 % of 4 cores depending on source type, filters, etc.) TMPG XPress v4.2.3.193 (65-100 % of 4 cores depending on source type, filters, etc.) Winrar v3.70 (~85-90 % of 4 cores on benchmark; ~75% in practice) x264 v0.55.663 (>99 % of 4 cores when doing the 2nd pass of a 2 pass encode) Benchmark/Distributed Computing Applications BOINC Clients (most of them) (>99 % of 4 cores) [email protected] SMP client (>99 % of 4 cores) Muon1 DPAD (~85 % of 4 cores) OCCT (>99 % of 4 cores) Prime95 v25.3 (>99 % of 4 cores) wprime v1.50 (>99 % of 4 cores) Games none that I know of yet If you'd like to contribute an application or game, please post the following: 1) Program name 2) URL to homepage of the program 3) The percentage as shown in the Windows task manager of the CPU's that are getting used @ peak or thereabouts along with a screen-shot of the task manager. Here's an example screen-shot of my task manager during the Noise Ninja noise reduction: Also, please limit the replies to quad chips only (yeah, I know this will limit the amount of replies, but this is after all what this thread is all about). Thanks! Note: I don't think this thread really belongs under the software section since it's specifically about software for quad core chips.
  19. All, thanks for the replies... my hope was to keep the list kind of semi-quantitative. If you offer up an app or game, please make sure that it's tested on your quad machine and you report the CPU usage. As you can see in my short list, Noise Ninja does use all 4 cores, but only 80 %. Thanks!
  20. ...I'm still waiting on the pics

    quad or dual?

    Speaking as a q6600 owner, I agree. Most of the time my cores sit idle. That said, there are a few apps that will use all 4 cores and use them efficiently at that. I'm speaking about x264.exe here. Unless you have a need to use it though, you are probably wasting your money on a quad at this point. You're also wasting your money every time you turn it on because they tap more juice than a dual does. The wildcard to consider is the future. If you plan on keeping the system for 3-4 years before your next upgrade, you may kick yourself in 1-2 years if applications/games get released that can use all 4 cores...

    weird lapping results

    The shine is actually irrelevant. How flat is the base of the HS and how did it affect your temps?
  23. Oil will work but beware of using anything too heavy like motor or cooking oil; you want something with a low boiling point. The best lubricant you can use is low odor kerosene you can get at any store that sells camping gear. Failing that, mildly soaps water will be just fine (like 1 drop of dish soap in 1 liter of water).
  24. @road-runner: the only way to know for sure if your CPU is flat is unfortunately to lap it. You'll know after about 20 seconds because you'll start to see the material come off the higher parts first like this: I started out w/ my Q6600 using 800 grit thinking, "Hell, I'll just polish the surface a bit just to see how uneven it really is." After I saw how bad it was, I had to finish the job Best $20 I spend in terms of cooling band-for-the-buck. Link to the rest of the thread with more pics/temp results.
  25. When my Ultra-120 X and I have to say I'm a little puzzled. The base where it should contact the heat spreader is not smooth at all, it's actually grooved! You can see a scratch which is where I gently ran my thumb nail over the surface; I could feel the rough edges. Have a look for yourself: Anyway, others encouraged me to lap it which I've never done before. After wrestling with the idea for a couple of days as well as reading many articles/guides, I decided to give it a go. $20 worth of sandpaper, a $2 piece of flat glass, and 4 hours of careful work (and sweat) later, I was left with a pretty darn flat HS. You can see by the pictures that this particular one was quite concave instead of being flat which isn't good for keeping contact between the HS and IHS of the CPU. Did it work you're probably wondering. The temp data as measured in speedfan.exe for a ~1 h x264 encode (uses all 4 cores with a CPU load of >99 %). I had speedfan log the temps (which it does every 3-4 seconds) and I averaged the whole data set per core for the 2nd pass of the 2-pass encode (the 2nd pass is the most CPU intensive). Room temp for both experiments was ~23
