  1. 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.
  2. Just updated the first post of the thread with the data collected... I counted 113 replies so far.
  3. 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.
  4. 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?
  5. Okay guys, just updated the first post of the thread to reflect the new replies... have a look!
  6. Just updated the first post of the thread with the data collected. Have a look!
  7. If you own a Q6600, please reply with your VID and the stepping of your chip. The VID can be found using coretemp. If you're using vista, coretemp will not display the stepping in some cases, so you can use CPU-Z (it's listed under "revision") to get the stepping. Here is a shot of mine for reference: If all else fails, look on the box your q6600 came in; the last 5 letters after the Q6600 in the production code will tell you the stepping. "SLACR" means it's a G0 while "SL9UM" means it's an older B3. Here an example shot taken by XtremeTiramisu to give you an idea: So, I have a B3 w/ a VID of 1.2875v EDIT: Here are the data as of 23-Sep-2007 at 7:30 AM based on people's replies to my VID thread here and elsewhere; just as a reminder, please do not post your VID from here on out as I won't be updating the data sets: *Histograms generated with SBHisto Total replies: 208 102 replies so far for B3 stepping Q6600s: (VID: # of replies) 1.1625: 3 1.2125: 1 1.2250: 1 1.2375: 1 1.2500: 5 1.2625: 2 1.2750: 13 1.2800: 1 1.2850: 1 1.2875: 12 1.3000: 14 1.3100: 1 1.3125: 15 1.3200: 1 1.3250: 31 158 replies so far for G0 stepping Q6600s: (VID: # of replies) 1.1125: 1 1.1520: 1 1.1625: 5 1.2000: 5 1.2125: 9 1.2150: 1 1.2200: 1 1.2250: 8 1.2375: 10 1.2500: 16 1.2525: 1 1.2600: 1 1.2625: 17 1.2650: 1 1.2700: 1 1.2750: 25 1.2850: 1 1.2875: 23 1.3000: 17 1.3125: 10 1.3250: 5
  8. 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...
  9. 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.
  10. 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 %.
  11. Great job judging by those pics. Here's my thread lapping the IHS on my Q6600 with pics and before/after results.
  12. 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.
  13. 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.
  14. 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.
  15. 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!
  16. 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.
  17. 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...
  18. The shine is actually irrelevant. How flat is the base of the HS and how did it affect your temps?
  19. 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).
  20. @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.
  21. Yeah, hardnrg speaks the truth. You can't tell by visual inspection if the thing is a 10-20 microns convex or concave. Just lap it and see.
  22. Here is a more detailed analysis of two difference vcore settings and the temps they produce on a Q6600 @ 9x266=2.4 GHz as well as @ 9x333=3.0 GHz. The two voltages I used were 1.112 V and 1.232 V (both of these are the load voltage, the actual BIOS settings were 1.1375V and 1.2625V respectively). 2x orthos ran for 30 minutes and the temperatures were averaged over the last 10 minutes of those runs (well after they stabilized). Room temps was 75-76
  23. Agreed; TIM can help in this regard, but I am convinced that giving it two uniform surfaces results in the most efficient heat transfer.
  24. I've seen people who posted screenshots of some software that allows you to change your FSB from within WinXP on-the-fly, but now that I actually want to try it, I can't find the name of the thing! Can someone post a link or give me the name of it? I have a P5B-Deluxe if that matters. Thanks!
