    AMD 64 X2 3800+ 2ghz @ 2.8ghz on air!

    Hi all thanks for looking,

    Two weeks or so ago i upgraded from my oc'd venice 3000+ (1.8ghz @ 2.6ghz on air in a way pretty normal) to my current 64 X2 3800+ Manchester core cpu.

    I overclocked it straight from 2ghz to 2.8ghz in one move (this is with ram speed reduced but i have benched both ways with no difference except stability) i tried cpu-z and validated and as you can see it is appearing as a toledo core yet still the l2 caches are still the 512kb of the manchester! After trying to look around and compare the closest i saw was 2.7 can anyone compare with me because im interested.

    ps. when i shift to new case after modding and getting right equipment im oc'ing further, im being limited by northbridge chipset overheating atm.

    The 3800 shipped with toledo and manchester cores. Difference being the Manchester started with less cache. where as the Toledo just has it disabled.

    Very good OC. Most of the higher X2's can reach that speed with bit of trial and error, not seen a 3800+ do it though.

    Thats a very good clock. 800mhz on any cpu is very impressive!
    Good job that I got my 2mb cache Toledo when I did! Im currently sitting at a stable 2.6 but I havent tried further because I doubt my ram can do nuch more...

    CoolerMaster ftw!!!

    Very nice overclock good job EllTheGamer.

    I have mine a 2.6 at the moment. Had it at 2.8 before my system clean up and reinstall. Ran fine at 2.8.

    Not meaning to be cynical but what stability tests have you done? I can suicide and validate at 2.9ghz with mine but its not 12h prime stable above 2.8.

    Ok -freebird try lowering the speed of your ram becuase it is never as tolerable as the cpu is, i see you have quite good ram but you are probably now at its limits there should be a setting for the ram somewhere in your bios that will say 200mhz try stepping back a notch and then taking your cpu further, if you do not have such a straightforward option try looking for a cpu/fsb:ram ratio setting and lowering that. Last of all if you have one make sure to lock your pci-e bus speed, if not then its not really a good idea to be overclocking your system as an overclocked pci-e bus is just waiting to go wrong.

    Well i have my pc running 24/7 and with background services i regularly (for hours on end) play gmod as a server with clients connected whilst recording with FRAPS or encoding movies in the background.
    I have also run 3dmark 06 & 05 through with no crashes (im not saying i got constant 60fps but i did it).

    ps. if it seems i told you some obvious points freebird just ignore them.

    hehe ok guys thanks very much for the advice .. even though this is not my thread..
    V sorry for hijacking
    Im a bit of a n00b at overclocking..

    I havent tried increasing the voltage .. but im not really sure how , or what the consequences of doing so are..

    I ran 3dmark 05..

    Score 10050 .. not bad .. go me.. lol ..

    Its quite nice at 2.66 .. but i would definitely like it at 2.8 since im sure it could handle that, ram/temp wise...

    So if i could just have a lil advice on voltage increase tht would be great

    Ty very much guy s

    Sorry i didn't read your post properly before. Since i have always been with budget boards (as im a teenager with no income) i have only been able to perform small voltage increases. But i havent really noticed much of a stability change i just run higher to keep me feeling safe with my cpu. I still strongly recommend lowering your ram speeds.
