Wowch, that's nice.
I can recall overclocking my San Diego 3700+ to around 2.8ghz at stock cooling without any uppage in the voltage or tweaking the memory. I never left it at those speeds because I thought i'd do quite a bit of damage.

Thanks for the suggestion by the way mate :)

No, it wont do any damage. So long as you don't go over 50*C, you wont hurt anything. Heat is really the only factor in damaging a CPU, so long at it stays low, you will be fine.

The only problem now is that I can only really get it to around 2.4ghz
I've dumbed down my HTT Link to around 600mhz, got my CPU Frequency to 230mhz.
Turned up my CPU Voltage to 1.50v and turned down my RAM to 166mhz.

Is there a detailed guide to Overclocking the AMD64 Range?
If i am able to get the CPU to around 2.6ghz i'll be happy :)

Cheers buddy

The Arctic Freezer pro 64 is what i use there a bit bulky but do the job great i could go even higher on my oc if i really wanted as top temp under full load is only 42c @ 3ghz seems as The Arctic Freezer pro 64 pushes air streaght out the back fans ive made my side fan suck air in so it feeds The Arctic Freezer pro 64 cool air all the time as well as the front fan which mainly cools my hard drive pushing hot air out the back is a great design to manage system air flow alot better i think.

Thats a pretty sweet OC on that 3000+. I never could get mine to go over 2.4GHZ.

Me neither until I dropped the multiplier from 9 to 8 which allowed me to increase the FSB by a lot. It's currently very stable and I could push it farther no doubt about that, but happy with it as it is.

Not bad mate, I'm going to give it a go on my AMD Athlon64 3700+ San Diego.
Apparently the San Diego Core is the same core used on the FX line of processors, well the early ones anyway.. I should be able to push it to around 2.6ghz with stock maybe.

I definately need a Heatsink though, I'm looking at the ASUS line.. What do you guys think is good from ASUS.. or is there any other manufacturer out there that you guys like.

Cheers,
boecke

no, the san diego is a newer core than the early fx's i think the early fx used a 130nm core, and didnt have sse3

the 3700+ on 754 used the clawhammer that was in the fx's, but without dual channel memory

Hmmm, fair enough :) Glad to hear it, heh.

HTT could also be called Hyper Transport. The ram speed should be under dram options and it's usually set to "auto".

Question:

I have a 3000+ 130nm socket 754 core on an Asus K8N mobo. I was reading this guide over since I'm considering OCing. But when I went browsing through my bios, it already had an option that would allow me to OC between 1-12%, 12% landing me around 2.4ghz. If I choose to use my bios' OC option, do I still need to play with the RAM's speed as well?

The BIOS SHOULD automaticly do that for you, I know my Tforce 550 will. Shouldn't 12% put you around 2240MHZ? Either way the bios almost certainly will downclock your ram.

Whoops. It is 2.24ghz. Would that extra 240mhz give me a noticeable performance increase? Also, I changed my RAM voltage from 2.5V to 2.7V as was suggested in the manufacturer's forum. That shouldn't affect anything right?

Yeah, that should give you a decent boost. What kind of RAM is it? It should be able to take 2.7 just fine, my corsair XMS DDR400 ran 2.8 default.

Ok i have a athlon 64 4000 san diego which im able to overclock in windows to 3ghz with the software that came with my Foxconn winfast 6100k8ma mobo. But when i try in the bios the cpu fsb resets to 226mhz from 250mhz is there anyway round this or is it the motherboards Bios limit?

cpu @250 oc = 3Ghz
multiplyer = 12
memory @ 166mhz = 400mhz normal operation
HTT 4x @1000mhz = Normal operation
voltage 1.376v
idle temp = 32
load temp =42
100% stable

I can now oc to 3gz from the bios after updating to latest bios thanks for your help guys:toast:
