How much can a A64 3200 be overclocked?

[marginalclue]

CPU-Z calls it a Manchester E4, CBI calls it a Venice E6 like the seller did. In any case, I'm running it at 2.4GHz stable (Prime95 for 14h 45m ) at 1.39-1.42v up from 1.36-1.39v. Current temps 38c idle, 49c stress.

I'm either going to up the HTT to 250 and stop, or buy an Arctic Cooler Pro 64 for my A8N-SLI board and shoot for 3.0 GHz. I figure I'll get to at least 2.8 around 1.5v, hopefully higher. Is it possible to clock a 3200 that high, and is it a good idea?

dont get asus if you want to oc instead get a dfi board

3200's have run as high as 3ghz.

Alot of people have hit the 2.4-2.6ghz area though, which it appears you already have. Which Asus a8n-sli board do you have (Premium, Deluxe, other)?


DFI lanparty series has been about the best board all around for overclocking on the 939 series, but alot of man. have a board that can do 300 1:1, and that's higher then most people are interested in oc'ing in any case.

I have the basic A8N-SLI, running BIOS 1014. However, it seems that pride goeth before the fall, or that I counted my chickens early, or something..... the system is stable as follows:

240 CPU, 10x multiplier, 1.40v
5/6 RAM divider, 2.5-4-4-7-1T timings, 2.7v
4x HTT

I changed the RAM to 2.5-3-3-7, failed Prime95 after 8h, 1m. Reset it and turned my attention to the CPU. Using ASUS AI Booster, if I move the CPU from 240 to 245, I get an instant reboot (same with 250). If I leave the CPU alone and up the voltage to 1.425 (2 "notches"), I get an instant reboot. The voltages can't be adjusted in the BIOS, only monitored (options: enable, disable). Next, I guess I'll loosen up the RAM....

to be continued

That's not a bad oc at all considering you can't mess with the V. You're probably hitting the limit of your cpu. I had to up the voltage at around 235ish. However that said, with my deluxe i hit a ceiling between 240-250 at 1:1, where voltage wouldn't do me any good. Most people using the deluxe have run in to the same problem, unfortunately. I don't know if you have the same issue with the basic or not. But it's something to think about.

Why thank you. I have the A8N-SLI vanilla. I actually did adjust the voltage from (according to AI Booster) 1.36 to 1.40. I've done some more research and I've found out that the A8N-SLI boards will not allow a Venice CPU to boot at a frequency over 240MHz with a memory divider. I probably got lucky in that I upped the voltage, changed the divider and tried for 2.4 GHz out of the gate. From all that I've read, you should be able to proceed with a 1:1 divider, memory permitting.

The odd thing now is that when I change ANYTHING in AI Booster, everything freezes. That includes the voltages to the CPU/RAM without touching the frequencies. Apparently I'll need some overclockable ddr500 ram or a new mobo if I wish to proceed. Then again, I'm pretty happy now... I would have had to pay double what I did to get a CPU running at 2.4 out of the box.
