Awesome thanks!

The divider goes from 100mhz to 250mhz.

I dropped it down to 100 and have my HTT up to 280 and so far its stable

Edit: I put the multiplier back up to 9 and Im running prime 95.

Okay, that is RAM speed non DDR. So 100 MHz = DDR-200, 133 MHz = DDR-266, 166 MHz = DDR-333, 200 MHz = DDR-400, and 250 MHz = DDR-500. Since you are limited by a 9x multiplier, to get 3.0 GHz, you would need an HTT of at least 333 MHz, which could be hard for some boards. (Do not expect to be able to get that high with a 9x either.) Most people need to use the DDR-333 (166 MHz) to get their RAM to acceptable speeds while overclocked, some need DDR-266 (133 MHz). For now, you want it where you have it to find the limits of your HTT; reduce your multiplier to 5x to test. Once you know the limits of your HTT, write it down and drop back to about 235 MHz HTT, put your CPU multiplier to 9x, and increase the HTT again until you are unstable. Reduce the multiplier by 1 (to 8x) and repeat until your are unstable. Keep doing this until you hit your maximum HTT. Take note of your maximum CPU speed (multiplier x HTT). Once you do this, put your CPU back to 5x, your HTT back to 235, and your RAM to 200 MHz again to find the limits of your RAM. With the limits of your RAM, HTT, and CPU, you can compute the "ideal" overclock.

Optional step: Set the HT Frequency to 5x, RAM to 100 MHz, CPU to 5x, and increase HTT until you are no longer stable. Reduce HT frequency to 4x and continue. This will yield your maximum Hypertransport.

Again thank you so much for the help. Its gonna take me a bit to do all that but I couldn't have gotten this far without you guys

here is my latest Cpu-z

Wish me luck

Good luck! The best overclocks need time, patience, and of course, love to get perfect. Overclocking is not something you can do on a whim unless you have an unlocked multiplier, but instead something you want to do for your personal enrichment.

I've already hit what I was hoping to get 2.5 ghz so anything from there is just icing for me. On another note with my HTT at 280, my multiplier at x9, and my Mem at 100mhz I decided to run bioshock and my fps were at 60 were the best I had seen previously was around 24 so thats freakin awesome for me!! These settings are the ones I had linked with my last cpu-z score. Prime 95 ran fine for the 21 mins that I let it go but my cpu got up to 57c. I believe thats acceptable but I was hoping for a bit better. I have 7 fans in total (including the gpu, cpu, and one removable hard drive fan) so I'm not too worried about the temp. I have a fan blowing directly on the ram also.

Yes, your Opteron 165 can run up to 65º C no problem. Once you get the RAM back up to speed, you should see your framerate go even higher. (Also do not forget, you are used to playing Bioshock with a single-core CPU; you have a dual now.)

Very nice fallout. Glad to see that you were able to find the settings that work for you.

Fa11ou7 · 1 Week Ago

The interesting thing, to me at least, is that as I am adjusting settings if I windows will boot its stable. I never have a problem in Prime 95. But if its unstable, the system will either not post at all or when xp tries to boot it blue screens and reboots itself.

One question tho, I'm having problems getting it to boot with the HT at 5x at the mid to upper ends of the HTT scale. This doesnt matter if the multiplier is at 4x or 9x, any ideas?

You can turn off the auto reboot by right clicking on "My Computer", then click the advanced tab, then in the "Startup and Recovery" box click settings. Then in the "System Failure" box un-check "Automatically Restart", click ok. Then it wont reboot.

As for system testing, prime is good for testing an overall system overclock or incremental HTT bumps.
For 939's I personally prefer to use S&M v1.9.1 (scroll down until you find it). It stresses the system harder than Prime. If there's a failure it'll tell you where it is. For instance, if I get an L1 cache failure, I know that my CPU needs more voltage. If I get an L2 or an FPU failure I know my temps are too high.

Prime doesn't really tell you much other than it failed.

If you decide to run S&M, for your first initial run make sure you choose short duration. You don't have to test the RAM (unless you want to) and the HDD test takes for freakin EVER!

Good luck.

I would recommend NOT running the HDD test unless you have a reason to. Else, you are just shortening their lives pointlessly.
