Overclocking Athlon 64 3000+ Venice Core Socket 754
Has any one here tried overclocking a Socket 754 Athlon 64 3000+ Venice
Core? It's running in an Asus K8N-E with the latest BIOS, 2 x 512MB Corsair TwinX C2 memory and an older nVidia GeForce AGP 4x video card. Everything is running at stock settings except I have the memory at 2.8v and the timing at 2.2.2.5. I initially had some problems with this CPU and was about to RMA it. It started working OK (tried it in 2 different boards). Now that the system is up an running I decided to see what the Venice core would do, especially since I have a 3 year warranty. Just changing the multiplier, the most that I can get is 2100MHz. Beyond that it wont post and I have to reboot and reset the BIOS. How fast should I be able to run this CPU? Chas. |

Should be able to get it up to 2400.

Overclocking Athlon 64 3000+ Venice Core Socket 754
As you'll see from those articles,
the multiplier is locked upwards (not downwards to allow cool'n'quiet) but you raise the clock from 200 upwards. This drags the hypertransport and memory along, so you set them slow such that the clock brings them up again. Don't pass their normal speed when beginning. First lock the memory timings or when you set it slow they may tighten up, not expecting that you're about to speed up the clock. The cpu may need a little more voltage. If you can run prime95 overnight with no errors it's pretty stable, but continue on for 24 hours. That's the very basics. Best to read the articles before beginning. You might first aim for a clock of 240. If you set pc3200 back to pc2700, then at 240 it will be at or near pc3200 again. You would have set your hypertransport back to 3x from 4x, so it would be 3x240 or 720. It's ok if the hypertransport runs slow because it's overkill already. Good luck. -- Ed Light Smiley :-/ MS Smiley :-\ Send spam to the FTC at Thanks, robots. Bring the Troops Home: http://bringthemhomenow.org Fight Spam: http://bluesecurity.com |

But that was a long time ago when others couldn't figure out how to do it on any board.:-) Just changing the multiplier, the most that I can get is 2100MHz. Beyond that it wont post and I have to reboot and reset the BIOS. Now I'm wondering how you changed the multiplier. I thought it was locked at 10x max. So it worked at 10.5? How fast should I be able to run this CPU? Well, if it's a Venice core it should go pretty high. With one exception it's the same as overclocking any cpu. multiplier times system clock = CPU core speed. You know you may need to raise vcore and lower the base ram speed to keep it in limits. The only other thing is the FSB HT link speed. it defaults to either 4x (800), and it must be lowered to compensate for the raise in clock speed, so lower it to 3x (600) and you should be good there for up to about a 275 or so system clock. -- Want the ultimate in free OTA SD/HDTV Recorder? http://mythtv.org http://mysettopbox.tv/knoppmyth.html Usenet alt.video.ptv.mythtv My server http://wesnewell.no-ip.com/cpu.php |
