Overclocking a AMD 64 X2 3800+ manchester

Ok yeah i got a x2 3800 manchester, but i havent seen anyone overlock one. is there any suggestions to what i could reach with a good watercooling system. I dont know when it runs stable or what not. yeah please help me out.

  1. With a good water-cooling kit, you could easily join Club 3G (3GHz). You'll want to check out an overclocking guide if you want serious overclocks. It will be stable when you can run 2 instances of Prime95, 1 on each CPU, for 12 hours and it doesn't crash.

    thanks, do you have any good links for this. By the way i am running a asus a8n sli premium mobo(if that matters). yeah cause i could use a tutorial
  3. http://forumz.tomshardware.com/hardware/Guide-overclocking-A64-ftopict126122.html

    The poster is a moron and that's probably the worst guide to overclocking ANY processor (it isn't really a guide, but a journal of what that person did when he was overclocking) but it's a start.

    If that doesn't help, I'll throw open M$ Word and write ya a quick one.

  4. I got the exact same processor and motherboard.

    Mine is overclocked to 2.7ghz with stock cooling.

    Before you do any overclocking I recommend you install the pcprobe software you get with the motherboard, it's good at telling you the temperatures of the pc and can give a warning if you exceed them.

    There are always different ways to overclock.
    Go into the BIOS and...

    1)Lock the pci/pciexpress but to 33/100mhz (the a8n-sli premium has this on auto by default and it should be locked)
    2)set your Hyper transport multiplier to *4
    3)set your vcore to 1.375V, you can raise it later if you find instabilities or need to overclock further but I find this works stable even with memtest and prime95
    4)set your ram max speed to 333mhz. Don't worry, this does not mean your ram will only run at 333mhz, infact it just means that your memory divider is at 12 and under standard HTT (200mhz) your ram will run at 333mhz.
    5)Set your CPU multiplier to *10
    6)now, set your HTT (it's the equivalent of the FSB) 240mhz, you might want to take it in increments from 200mhz->240mhz to be safe but it should be alright
  5. try this link :-)


    i got a whole lot of info about x2 s' helps to know ur chip ID ...
  6. thanks, that helps alot
  7. With your premium board you can get a max of 1.5vcore or 1.55vcore depending on which bios revision you use.

    This is one of your limiting factors.

    On 1.5vcore you can hit, at 1:1, between 230-280fsb depending on cooling/memory/cpu model and week codes.

    Add 8-12% or so to your overall overclock if you want to run with a divider. Assuming cooling doesn't become an issue.

    The dual core runs a little warm when you oc it (compared to the single cores...which is something to keep in mind, for those of us not keeping our rooms at 20c). I have mine running 2.5ghz 250 1:1 with 2gb of ocz plat. Thats on the Asus a8n-sli premium board.

  8. thanks alot on the information, all i need is a new damn bios chip. Thanks.
  9. I just helped my brother oc his X2 3800+ to 2400MHz on stock voltages. He has an Abit KN8-SLI mobo with 1GB Corsair XMS DDR400 (3-3-3-8)... We probably could have gone higher, but he didn't want to have to buy a new cooler (he's using the stock HSF), and I figured a load temp of 55C was probably warm enough. Besides, he was pretty pleased with the 20% oc anyway...

    With a bit better cooling, I'll bet this proc could have done 2.8 with little trouble. I'm surprised we got as high as we did without having to raise voltages...
  10. I have a Asus mobo and it has a option where you can overclock in %'s
    It does all the work for you. I overclocked my X2 3800 to a 2.2
    I will overclock to a 2.5 some day, but I don't want to fry my processor. Money is in short supply right now. In four months I will buy the FX-60 and overclock it to a 3.2 or a 3.0
  11. yeah the FX-60 is great bro, but you can get an opteron 170 to 3.2 and its really less expensive, plus the FX-60 isnt that great. wait for the December AM2 AMD processors. SAve your money cause those processors will be hawt. and overclock like a madman
  12. A new bios chip? You tried flashing your bios and lost power?
  13. no my current bios chip doesnt function fully, its has only minor errors and the ASUS support team told me to order a new one , but there bios department is run by 1 person. she has an answering machine and your supposed to place orders on that. Go figure. Anyways yeah i think i need a new bios chip to run eiffecently
  14. I've had to replace a bios chip before...but that was because of a bad bios post for that board.

    I've never heard of anyone replacing a bios chip when it was working...

    Have you tried just flashing the bios to a different version? With my Asus all i have to do is download the file, upload it to the chip (while in windows), and reboot.

    Maybe i'm not getting the full extent of your problems. What exactly is going on?

    Edit: Please add your full system specifications as well (see below).

    At Stock settings (ie not overclocked)...
    CPU Revision: (E3, E4?) You can find this in cpu-z
    Motherboard bios rev:
    HD and connection type:
    CPU temp at 0% cpu usage:
    CPU temp at 100% cpu usage:
    Motherboard temp at 100% cpu usage:

    other questions....
    Are you using Nvidia Firewall? if so disable it.
    Are you using Nvidia ide drivers? if so remove them, use windows drivers.
    Are you using the AMD driver?

    fyi - it took me about 2 months to get a bios chip from Jetway...I doubt Asus is as bad as Jetway is...but still...
  15. ok ill update you on the info as soon as i get home ,i am at girlfriends house atm. IT will be around 4pm est. time

    This ram could be:

    -CMX512-3200C2 XMS3200 XMS3202 v5.2 0529061-0 = Promos -5 Rev

    -CMX512-3200c2 XMS3202v1.5 0522078-1 = Winbond -5 UTT

    The list goes on and on...So we still don't know what kind of ram you have. =) We need to know the exact details of the chip, to know most likely how far you can overclock it 1:1.

    *-The TCCX is either TCCC or TCC5 chips.
  18. CMX512-3200C2 XMS3200 XMS3202 v5.2 0529061-0 = Promos -5 Rev
  19. You would have the promos stuff. =/

    I know very little about it. The people i know that have purchased it, have resold it because it didn't oc very well for them.

    But honestly i don't know what they expected either...So i don't know what that will oc to. =( Sorry. I'm of no help at this point. Google is your best bet probably now.

    Or you could do this manually, ie the long way...

    If you're going to do this the long way, take the side off your case (since you said it doesn't have very good ventilation), and have some program that monitors your temps so you know how hot you're getting. I like to have the nvidia's ntune nmonitor running, since it leaves you a graph of what temp you've been running.

    Drop the multiplier down to 8x, up the vcore voltage to 1.5v (cpu voltage), change the memory settings to 3 4 3 10 12 14 3 3 1T 2.8v, and start increasing the fsb by 2-5mhz a pop. Each time you change it, run an instance of Super Pi 32m in windows. If you want to save time, you could start out at 10mhz a pop until it gives an "Error in rnd" error or something when running superpi, or until it doesn't boot or until 220fsb (i'd probably do 10mhz up to 220, then start doing 5 until it gives me an error in super pi, then i'd go to 1-2mhz until i couldn't go any higher, then i'd try increasing .03-.05 voltage on the ram to see if that makes any difference [i don't remember off-hand at what lvls you can increase the memory [edit] voltage on that mobo...]).
  20. thanks alot i appreicate it. Think i can email or chat with you if i have problems?
  21. I can't this weekend. =(

    You're welcome to send me messages today though. However, I've got a lot on my plate today, so i'll be in and out of the office alot. This weekend i'll be out of the state, so i won't have ready access to the internet.
