amd athlon 64 3000+ overclock fsb and dram timings

post #1 of 56
Thread Starter 
hey guys, im trying to overclock my amd athlon 64 3000+ as i know it has alot of overclocking room. it runs 35 degrees idle and about 50 under FULL load on a stress test. this cpu is rated i believe to 65 on my motherboard and i have heard of people overclocking this to nearly 3ghz. the problem is that this cpu is clock locked at 9x and there is no way to unlock it. the pencil trick does not work on this cpu. the only way that i can see this proccessor being overclocked is through the bios and increasing the fsb. i am completely comfortable working in the bios as i have been for the last while. i can change the fsb to whatever i want in my bios and its great and all but my computer wont boot if i go past 225 so i leave it at 220. the stock fsb is 200 so i did overclock by about 10 percent but i would like to go alot higher than that. now what i mean by it wont boot is that it will display the logo screen as normal(the mobo loading screen) then when it would normally boot windows 7 it just shows the mobo information and after 3 seconds it restarts. i have control over the dram frequency and i set it for a max of 110 mhz and i went to the os and sure enough it is running at 110mhz my dram supports up to 200 mhz as it is ddr-400. i set my dram timings and dram settings all to auto and my motherboard is made it 2.5-3-2-5-7. my ram isnt limiting this so i would like to know how to push the fsb higher.

my computer specs:

motherboard - lanparty nf4
memory - ddr 400 value select 2 512 mb sticks
proccessor - amd athlon 64 3000+
gpu - NVIDEA geforce 6600 GT
bios - phenix award winning bios

im not sure about the psu specs but it is a good one so dont worry about me running outta power here.
also my cpu has a huge heatsync with a large fan on top and the case has numerous exterior fans to keep it cool so the ambiant case temperature is very cool and i believe that will help me achieve a higher overclock.

TO SUM ALL UP I NEED TO PUSH FSB HIGHER AND NEITHER RAM OR CPU IS LIMITING SO WHAT IS AND HOW DO I STOP IT?

really confuzed i still cant get this overclocked....

So.... What's the problem? You said you know how to push the fsb up and neither the ram or CPU is limiting...

its becase of your cpu voltage AMD has it set on the K10 chips not to go over 1.55 volts and your right thier you hit the wall with that cpu and motherboard

actually ive seen many people push their amd athlon 64 3000+ to nearly 3 ghz. the cpu isnt limiting and i know it isnt. the ram isnt. i really dont know what is limiting me raising my fsb???

btw i have the option to raise the fsb but i cant raise it over 220 (200 stock) otherwise it wont boot

so im still trying to overclock it and im wondering if it is the ht link holding me back or as the old boards use to call it the ldt.... im not sure if they are holding me back but the ht seems to be running at the same speed as the fsb when i open cpu z so the ht is running at 220 mhz... is that to much?

but i looked at a website and it said that the ht link should be around 1000 mhz.... so is mine to low, btw i have control over the ht link multiplier in bois so no issue there

1 not all cpu's are equal thier are alot of factors to it just becase one over clocks to 3MHZ dosent mean they all will its why they are underclocked by the factory so they know all of the same will hit a cirten mhz or ghz
2, the mobo is part of the equation and just like the cpu they are advertized at lowwer sppeds so they can say our board will peform at this level
3. ram same thing as the cpu and mobo
your over clocking thier is no set in stone number you will get it all depends on a whole setup it all works together in a syteem anything you get over factory settings is good but thier are some things set in stone you get over voltage settings things burn up or crashs the same is true for frequancy setting things dont work you change 1 thing and it has afect eles where

ddr2 ram waxs at 1000mhz on ht and you wont get the cpu faster rasing it but it needs to go up in perportion to how much you raise the cpu as you make it faster you ht needs to go up to handle the faster cpu but rasing just the ht wont make the cpu faster or make you able to make the cpu faster your mother board has rasied your cpu voltage to acomadated the higher over clock you put on the cpu you are at the max voltage for the cpu on that motherboard on a diffrent mobo you maybe able to get that cpu up to 3 ghz and maybe not it could be the cpu itself may not be able to get to 3 ghz

btw im not at the max voltage i have about .150 volts to go and also i think i should be able to raise the fsb up just a bit more than 220 because at 220 i can run a stress test and it runs perfectly stable but then at 221 it wont even boot? also my ram and my htt both have there own multiplier and i can limit their frequency so im not affecting the ram nor the htt... what is holding me back?
