  1. +1,104Mhz over standard, on a twin fan air cooler, it's my daily used setup.
    1.46V 45nm E8500 dual core. Highest ever Tjunction temperature was 61C.

    I have also overclocked it and booted Windows 7 to a rather unstable 4.75 @ 1.6V. 1.8V was a bit more stable but temps were stupid. Will not boot at 5Ghz though :(
  2. The one in your sig? Impressive. =D
  3. Q6600. Thats all I can say. 600MHz for free. Well actually at a lower voltage than stock too. Woot.
  4. i7 920 @ 4.0 Ghz with games and 3.2 Ghz daily
  5. Q9550 @ 3.4ghz like nature intended.
  6. Have a
    Q9550 @ 3.6ghz on stock voltages (1.23VID on this one). Mmm...

    Had a
    E8400 @ 4.0ghz on 1.38v

    @SpidersWeb

    Nice OC, I freaking love that CPU. :)
  7. Q6600 @3.2GHz =800 MHz OC 1.375V, temps up to 60C under prime95, Speedstep enabled, running 2.4 iddle, 3.2 under load . Can got to 3.6 at higher voltage but gets a bit hot under load and not really necessary.
  8. AMD Phenom II 920 @ 3.361 GHz (2.8 stock) with 1.325 volts (1.35 stock)

    prime 95 loads 47 C with 23 C ambient
  9. Q6600 @ 3.2Ghz with 1.28V, prime 95 load about 65C. cant get it higher than 3.3Ghz no matter what voltages :S

    Thanks :)
    Wish I could take credit, but it's really the quality of the E8x00 series CPUs. Mine isn't even a great one (seen many higher, and some the same but at lower voltages). My favourite little achievement is the 333Mhz -> 533Mhz on the FSB :) not that it makes a huge a difference, but running the 1066 RAM at 1:1 just feels 'right'.

    4Ghz for you, and you're barely outside Intel's maximum recommended voltage range. I'd say that's just as good if not better than mine.
  11. PII 955, ocverclocked to 3.8...
  12. You guys put me to shame.

    I can't even get my i7 920 to cold-boot properly at 3.0GHz with a DX58SO (prolly do not enuff voltage, but I'm too lazy to find out)...

    And I barely got my E5300 to 3.0GHz at 1.26v with a Biostar P43, trying to do 3.2 at 1.26-1.27 (left it on auto voltage since the mobo doesn't allow you to manually set votlages) and it crashes within 5 minutes.

    I either lack proper OCing skills, or I keep getting "meh" chips, or all the mobos I've bought suck for OCing...
  13. Sounds like you're not using overclocker orientated boards. (P43 is the cheap version of the P45, and Intel boards don't rank highly with overclocking).
    Go with boards that rate highly on overclocking benchmarks.

    Also I think your E5300 could've used a bit more voltage :) If you can't manually set it, that blows. Can be lots of other things though, there is a lot more than just Vcore.

    I'd expect you'd be able to get well over 3Ghz without cold start issues on the i7 920, I suspect your intel board is keeping every voltage as low as it can.
  14. q6600 @ 3ghz.
    I waited about a year and a half before i overclocked cause I had a junk GPU in it. Once I upgraded to a GTX 260 I juiced it to 3ghz and it made a huge difference. Been running rock solid since march without a hiccup. I think I did have a hung boot once or twice since overclocking, for a total of maybe 5 times in the 2.5 years ownership. Reset button fixxed it right up.

    Running at 1.275volts, I think thats slightly under stock voltages but I am too lazy to look it up or care. I could boot to windows at 3.6ghz, but I BSOD later cause I didn't put more juice to NB/SB.

    Two year old system that will run most games I play at near max settings at more than playable fps.. Why push it further? Maybe in a year or two when my system is "slow" I might throttle the CPU and sqeeze a little more life out of it before I go to a i5/i3 system.
  15. AMD Phenom II X4 810, not over clocked, but it is under volted down to 1.1875v (from 1.325)

    though at stock voltage i hit 3.2GHz no prob
  16. And if you are overclocking you should always buy the parts. Asus or Gigabyte are usually failsafe. I am a gigabyte fan for the last couple builds and after seeing comparable reviews (like the p55 toms comparison that Gigabyte was best overclocker).

    I personally don't need more features or Sli/Crossfire. I understand you can get some great deals messing with it but graphics cards are meant to be replaced every few years anyway.

    Single GPU, aftermarket cooler, namebrand mobo and you can expect to get some life out of your system.

    Get either Asus or Gigabyte. Tend to OC pretty well.

    Also, P43 as said is like a lower version of a P45. Think of it like a Celeron or Phenom X2/X3. Just a chip that didn't go par.
  18. Q9550 @ 3.6 stock voltages. As soon as I get my mobo back from RMA I plan to have the same specs in my media center. I only want it OC as I will do some gaming on the 10' fixed projector screen and my new ATI 5770 coming in the mail in a couple of days... ;)
  19. I hardly consider taking an i5-750 from 2.66 to 3.6 a "heavily" overclocked rig.
  20. I've got my other rig (Q9550/Foxconn Black Ops) overclocked to 3.6 on stock voltage. They only thing I messed with is the FSB.

    Of course, each CPU varies in terms of overclocking potential. But considering 3.6 to 4.0 is the upper limits of what the i5 can do with air cooling (with good air cooling), I would say it qualifies as "heavy" overclocking. Most 3.6's I've seen done on hardware reviews use voltages of around 1.3v, and anything over 3.6 usually goes into the 1.4v range...that is essentially approaching the upper boundaries of Intel's recommended voltage levels.

    I'd consider light, or light-medium overclocking to be possible with stock. And anything that requires a 3rd party cooler that costs $50+ probably falls into the medium to heavy overclocking range.

    That's roughly 40% OC. Just curious, what's considered a heavy overclock then? I guess I'm still stuck in the mindset of the P4 Prescott days that you were lucky to get a stable 10-15% OC, lol...
  23. wish i could say my cpu is overclocked but it's not. Even if i wanted to my motherboard caps may blow if i tried. (yes i have an old computer.)
  24. 550 @ 3.850Ghz @ 1.375v *Daily*

    4.050Ghz Max OC for benching @ 1.425v
  25. Intel Core i7 920 C0 to 4.4Ghz for benching. The Core i7s are phenomenally easy to overclock.
  26. Phenom II X4 940 stock 3.0Ghz overclocked to 3.5Ghz
    Phenom 9850 stock 2.5Ghz overclocked to 3.0Ghz
    Athlon X2 7750 stock 2.7Ghz overclocked to 3.0Ghz
  27. Phenom II X4 955 3.2GHz @ 3.8GHz
  28. Phenom II X4 965 @ 3.8GHz
  29. double

    Phenom II X4 965 @ 3.8GHz


    --------------------------

    Only 3.8GHz with a 965? I have the same OC with the 955.
  31. they are esentially the same chip 956 just clocked a bit higher at stock speeds but over here the difference between a 955 and 965 is $5
  32. ^Ok, $5 in your country, in my country are $150.
  33. Core2 Duo E8400 @ 3.6ghz (600mhz OC) one step above stock voltage, although here in my office I cannot quite remember what that is..lol

    I run it 24/7 stable it is my daily gaming pig.
  34. the 955 is $208 the 965 is $213 here
  35. ^jejeje send me one, I bought the 955 on newegg at $245.99 eight days after arrive to the stores.
  36. My favorite rig is my 2p slot1 P!!! workstation w/Win2k --- no OC but that SCSI RAID is da bomb.

    HTPC rig has an unlocked Sempy 140 OC'ed to 3.4GHz and undervolted with C&Q to 960MHz and 0.9v --- seemed to run fine at 3.8GHz but my idle was above 1GHz and I couldn't have that - LOL --- sleeps at 6w.
  37. I overclocked my P3-667 too
    she's now a 750.
    Still as slow as hell though.

    Have an all SCSI Compaq P55C 233Mhz MMX. Being Compaq I think overclocking chances are slim, but a decade ago that would've been a badass machine. Still boots Windows NT Workstation 4! (although I don't know the password, cause I am dumb yo)

    Got a bunch of Athlon XP's, but AMD was pretty anti-overclocking back then, and I'm too lazy for pencil mods.

    Edit: and I bought a new 775 cooler so I could rebuild my old P4 and see how far I could O/C it (just for fun)....... but ........ I lost the processor :( and the whores on local auction sites want more than pocket lint for them :(
  38. Spiders, what P4 you looking for? I throw them away everyday lol. For the cost of shipping I might be able to send ya one if you really want to OC one. I think I have three sitting around my office as I type this...unless they went out this morning with the E-dump..
  39. Oh legend.
    LGA775 anything 2.8Ghz up.
    Mine was a 3Ghz with HT.

    Send me a PM if you find something!
  40. I will keep an eye out, if I come across one of that nature I will PM you--shouldn't be more than $5 to ship out.
  41. and there was a true cedar mill over here up for $35

    woah, nice OC on a non-D0 chip.

    It might be Microcenter =)
    They sell i7 920s for $200, and Q9400s for $140
  43. Microcenter has the best deals on CPU's more often than anyone. My Q9550 I got for 179.99 can't be found for less than 250.00 right now...
  44. AMD Phenom II 955: normally on 3.8ghz with 1.4-1.45V for absolute stable use, any lower and I get occasional blue screens during heavy load.

    I've been able to run it 4.0ghz (20x multiplier) with 1.55V with my window open over a very cold allnighter for about 6-7 hours and @ around 10AM it started to get close to the 59C, meaning BSOD for AMD CPUs.

    As the winter comes nearer, I can probably test out how high I can OC it, but this is all done on air cooling (Antec 902 + Mugen Scythe 2), so I doubt I can really go significantly higher.

    Put your computer next to an open window and wait for the snow. =)

    I bet you'll get ambient temperatures of 5-10'C and CPU idle temps of 20'C :D
  46. Apparently it seems Intel CPUs are more overclockable since their out-of-the-box values are kept at a lower clock speed?
  47. Q9550 OC'd to 3.6 GHz @ 1.3625 volts, load temps 58 - 61 C. C3 stepping :(
    Q6600 OC'd to 3.6 GHz @ 1.425 volts, load temps 61 - 66 C.
    E5200 OC'd to 3.78 GHz @ 1.45 volts, load temps 52 C. Higher than average VID :(
  48. Here's a foolish question for you guys:

    Is it possible that overclocking makes your CPU run slower? Heard one of the genius' best buy salesmen (who also tells people that a dual core 2.6ghz runs at 5.2ghz since it is 2.6 times two cores) saying this to someone.

    I suppose, if you didn't know what you were doing and had a bad OC profile it could hinder performance--but with proper cooling, voltages, timings, components...how could it possible make it run slower? lol

    Any thoughts?
  49. Where is the option for ALL of the above :p
