  1. Well it is able to overclock to 4.0ghz but if you wanna replace it in a year, im @ 3.6ghz @ 1.45vcore. Use bios always. Step the multiplier up .5-1 at a time and run prime95 to test stability, i test it for like 10-15 mins if no errors it wont crash anytime soon probably and just go again. Rinse and repeat.

    I'm on a 110mm V1 cooler from TT as well, i dont think you need to worry about temperatures.

    If your board has ACC or Clock control enable it, you will go higher stabily.
  2. sweet thanks
  3. More than likely you're not going to hit 4.0GHz, at least without a good water cooling setup. At around 3.8GHz you have to pass the 1.5V barrier which is farther than most people would like to go.

    EQPlayer How are you running 8 gigs of 1066 on m4a79 board? You can only use 1066 on one channel. I could only find 2 2gig sticks, did you find 2 4gig sticks?
  5. You guys are both wrong. Majority of 940 owners are getting 3.6GHz to 3.7Ghz. Some are getting in the 3.8 range but if anyone is getting higher they are unstable. Even with a decent watercoooling setup.

    No, I run 4 2Gb sticks. I set the RAM to 1066 in BIOS. I can post a CPU-Z shot if you like.

    Just because AMD likes to say you can't run it at 1066, and the BIOS defaults it to 800, doesn't mean you can't go in and manually set it yourself.
  7. That much Ram is a waste. You will never utilize 1/3 of it.
  8. eh, what's 8 gigs of ram for?

    4 gigs is the sweet spot, and there's a noticeable gain compared to 2 gigs in terms of what program you are using.\

    Though, what program needs 8 gigs?

    Extreme overclockers will use 1 X 2G sticks to overclock. Anything more is a waste. Most can get a slightly higher overclock with 1 stick but with Vista since it is a resource hog 4G will probably be better. The only thing you need 8G is if you are running applications such as cat or multi tasking in a huge way. 8G is a total waste of money. It does not help your system 1 bit over 4G which the average user will never come close to using.
  10. I use 8Gigs of ram for 1 reason..... People dont realize that Vista64 Bit is designed to use what your hardware has to offer. When I had 4gigs I would idle (after 8mins of background program checks and such) @ around 1.1 to 1.2 gigs ram. With 8gigs I will idle @ 1.5 to 1.6 gigs. Not saying 8gigs is the way to go, but Vista and the soon to arrive windows7 checks your system to see how efficient it can run on it. Its not a game thing just an OS thing. I do not and will not see a difference in 8gigs vs 4gigs as far as gamming goes.
  11. That's fine and dandy but most extreme overclockers will run 1 stick to get max overclock. It may not be much higher than 2 sticks but 4 sticks for overclocking even with 64 bit I believe is unnecessary.
  12. As far as gaming same thing. You have 4 sticks especially in ganged mode. Each core uses all 4 sticks causing more communication. Even with 64bit, you will never use all that memory unless multi tasking and high memory applications which games will NEVER USE ALL THAT MEMORY. It is a waste. This is why I am just short of 3.7GHz and you are only 3.5GHz. You should easily get 3.6Ghz out of a Phenom II 940.
  13. No. I can get 3.7gigs no prob. I just dont like to be over 51c full load. I have bounced off 3.8gig just to see what I can do. I have been trying a lot off different things. I dunno what "They" do, but I try to run as good as I can with low temps. I have been running these settings for 2 hrs prime so far. Just stopped to check emails. Temps never got over 50c. OCCT I ran for about 35min. Everest for 1hour. I dunno how to put link on this but I will try. http://valid.canardpc.com/show_oc.php?id=554567 BTW. With this FSB the L3 speed is crazy. That was what I was looking for and I got it.
  14. The memory is very much used. I have 2 monitors. I game on 1 and I use the other to check web, emails and burn music for my wife (sometimes the music) I even watch movies while I game (If i'm doing repeditive task or waiting on friends to come online). I have bounced off 5.8 and a few time with Blu-Ray 6.3 gigs. It never interupts my game. Sure the CPU is about 75-85% loaded if Blu-Ray is going with a game, but that is what a quad is for. I do everything with my rig. TV,movies,music,games and web stuff. The 8gigs is very much usefull. The only time you will ever see a difference in numbers from 800mhz to 1100mhz is in virtual benches. The human eye will never notice it. As long as ur GPU is at tops you will never see the difference unless you have 233mhz ram up against 1333mhz. then maybe, but I game side by side with my friends sometimes and 1 of them wishes he never spent the money on the I7 Intel, because he was able to see no difference at all. His ram is clocked at 1600mhz at that. Twice my speed but equal on the visual. If you want virtual benches then have fun, but a freakin cheap ass HP or Dell with the right GPU will game just fine. 3gig, 4gig, or 8gig. No one can tell the visual difference.
  15. I have the same board and chip and have it running stable at 3.6 GHZ. Have gone higher, but certainly not stable enough to be reliable, nothing like getting stopped in the middle of a fragging session! I have 4GB of ram at 1066 and the box is just great!, BTW no vcore change required, runs solid at 46c at load.

    You are exactly right I have a Danger den setup W/ mc tdx block and 2 BI 240GTX rads and the d 5 pump and i can get stable at 3.8 at 1.585v load temp Prime 95 46c anything after that well you know what happens

  17. Hi what about this for my first overclock from 3.2GHz to 3.8GHz using amd overdrive as the cup clock will not go lower that 200 in the bios

    amd overdrive listed temp at 31.5c-32c idle on all 4 cores and 47.5c-48c on all core in its 1hour stability test/OCCT also read 31c-32c idle,47c-48c on full load

    when Intelburn test was used full load temp was 48.5c-49c full load on both the above

    My system

    Case----------------------------------- Coolermaster cosmos 1000

    PSU------------------------------------ Coolermaster Real Power M1000

    CPU------------------------------------ AMD phenom llx4 Black Edition 3.2GHz overclock to 3.8GHz (Cpu multiplier x20 ,HT ref.clock 190,CPU vid 1.500)

    Motherboard------------------------- Asus M4A79T Deluxe

    Graphics Card-------------------------Nvidia Geforce ENGTX260 TOP SP216

    Cooling(CPU)--------------------------Corsair H50-1 Hydro series

    Ram------------------------------------- Corsair Dominator 4Gb DDR3

    Harddrive------------------------------ Western Digital Caviar Black 1TB
  18. I ran my x4 940 @ 3.6 for 6 months with a corecontact cooler on it and it wasn't until then that i tested it with AOD which even though the core survived 6hours of P95 and Orthos it failed AOD within minutes.

    I now have built a waterloop for my new 5870 and just to play wanted to see what my max OC was..
    I hit 4Ghz but it was pretty unstable at this speed.

    I tried Cool'n'Quiet with stock speeds to see if I could get a very efficient setup as I don't want to clock it at present however in Win7 the Cool'n'Quiet just made the system unstable and buggy.

    I now have everything on stock with the fans on the loop running on low and this still gets me a max load temp of 36 degrees.

    (None of this matters as I have not had a stable internet connection at home for over 2 years now) :(
