Hi Everyone. I am looking to overclock my AMD 3500+ a little more and can’t seem to cant it any further. It is a Winchester core. Right now it’s running at 2.62 GHz (237x11)
My Specs are:

Asus A8N-Deluxe
AMD 3500+ 237x11 @ 1.5 volts
2 gb Corsair XMS 2.5-3-3-7 @ 2.85 volts

Temperature right now is not an issue. It running at 30 idle and about 40 at load. I basically want to get it as high as I can. I am kind of new to overclocking but I do know some. Thanks in advance.

After setting my ram to ddr333 I was only able to get my FSB up to 241 before Prime95 started to have errors. Im guessing that i hit the max for the processor. My voltage was 1.55 and that is as high as my Asus A8N will go. Im guessing that over clocking my memory is prob better than getting that extra few mhz. Meaning that when my FSB is 237 and ram is at DRR400 is better than having my FSB at 241 and my ram at DRR333.
When at 237 my ram timings are 2.5-3-3-7 which is still pretty good, but when i go to DDR333 i can set them to the stock 2-3-3-6 because my ram is no longer overclocked.

Any insite would be great!

I may have gotten lucky but I could send my 3500+ to 2.55Ghz without pushing it much or even touching RAM and timings. Maybe mine is just juicy.

edit - Asus A8N-E.

Is that a "Venice" core?

Yeah, I just saw he has a Winchester.

I was able to push my Manchester 3500+ to 2.64 Ghz with 11x multiplier 3x HT multiplier and 240mhz FSB. Voltage @ 1.46.

Lowering the HT multiplier to 3x was really the key. I increased my max clock from 2.45 to 2.64 Ghz after that.

Need to play with RAM today. 2-2-2-5 @ 200mhz lousy. More is possible. Using an Arctic Cooling Freezer64 Pro.

Temps have become a problem: 35C idle and 58C under prime95 load. Any suggestions there? Using the Coolermaster Centurion case, wiring is a bit ugly due to having a server PSU with many leads. Zip tying the wires out of the air path decreased temp 3-4C.

Also, when I push the voltage above about 1.5, the system will switch off immediately after saving BIOS settings. PSU or MoBo problem? Anything I can do here?

I should repost some stuff:

244x11x4 = 2.685 Ghz
1 gb valueselect PC3200 @ 2.5-3-3-5 200mhz (i.e. 400)
1.54V CPU
2.93V RAM


Full load = 64C. Hot but stable in SuperPi, Prime95, and Call of Duty 2.

Those temps are to be expected, I would say, and not abnormal or really that bad at all. 58C under prime95 isn't that rough.
