Ooooold OC Guides (athlon 64)

post #1 of 7
Thread Starter 
I've not had much luck looking but I've got this old Athlon 64 Venice 3500+ CPU that desperately needs some punishment.

But... I've never OC'd an AMD chip before so any old guides people know of would be a great help.

Other than that
From what I've read CPU temps needs to be below 65oC, but what about the NB, how much cooling is that likely to require?

I've modded a larger heatsink with a fan to cool it however I'm wondering if I might need to extend my liquid loop.

On top of that it would be good to see other people's voltages/clocks for this type of processor if anybody has any.

Well, AMD chips are sort of simple IMHO. I never owned an Athlon 64, but have owned/OC AMD chips since the first Phenom chips.


First
I would go to the bios, and up the multi by a notch and try to boot, if it does, run Prime 95 or some other stress test to check for heat, and stablity. For these, I would test for at least 5 minutes, to get a rough average temperature.

If it fails to boot....
Bump the voltage up by a notch and try to boot, if it does, follow the instructions above. If it still doesnt, keep bumping the voltage up one and booting till it does.

If it crashes on the stress test, or gets too hot
If it crashes, you need more voltage. Go back into the bios, and bump it up one, stress test, until you are stable. If it gets to hot, try to reseat your cooler, it looks like you got a nice setup there, should do the trick fine.

Second
Once you are stable at that first multiplier bump, feel free to bump it up 2 at a time if you are impatient. If it doesnt boot, apply a little more voltage till you do, and if needed, more until you are stable.



WARNING
Unless you are doing this for ****s and giggles, 1.45 is about the max on this chip for 24/7, 1.5 being the absolute most you should think about going. If its a suicide run, then have at it.

I have seen these chips run at 2.9ghz at about 1.45/1.46v, but your milage may vary. You may be able to reach 3.3ghz or so, but don't expect more than that haha

Forgot to mention, temps under 55 is the sweet spot, but 62 is the limit. If you are just benching for a few minutes, 65 should be fine, hell, 70 might be. But for prolonged usage, keep it under 60 is my rule of thumb for all my AMD chips. I dialed back my 4.9ghz clock because I reached 64* sometimes in-game, but hovered right above 60.

Check out Durches AM2 OC guide. Although it is not a socket 939 guide, most of the steps are exactly the same, but socket 939 uses DDR1 instead of DDR2.

Also, for max voltages on a venice core? You can go quite a bit over 1.45v, seeing how the stock voltage is 1.35-1.4v. Back in the day it wasn't uncommon to see people get close to or just over 3GHz with one of these, and the voltages of around 1.4-1.6v were super common. Anything past 1.65v or so though and I'd start worrying about longevity. Its because these are older chips made on a larger manufacturing process (90nm instead of the current 28-32nm we're seeing on Kaveri/trinity/richland/bulldozer/piledriver), and those larger transistors can take more voltage.

Source

Also, you'll notice that the max temp listed for that processor is 49-65c, which is fairly low. So keep an eye on the temps. I've historically tried to keep the temps under 55c max, but have always rested better if I can keep them under 50c.

I ran my Windsor core Athlon x2 4600+ at 1.55v for two years, and its made on the smaller 65nm node, so I feel anything under ~1.6v should be fine for that venice.

Good luck smile.gif
