| 785837 | 2009-06-27 04:14:00 | Good stuff, what are your temps like? I tried to get mine further but it just wont. Have to settle for 3.6ghz. It did boot to windows at 3.7ghz though. then bluescreen when opening orthos |

| 785838 | 2009-06-27 06:08:00 | now FSB at 370MHz with multiplier at x7... testing stability with prime95 for hueybot3000's info, with a stock cooler, with the prime95 torture test running, temp is about 57 to 60 degrees. Idle temp is about 38 to 40 degrees. To me personally it is getting quite hot now, I believe once I start increasing the multiplier it will get much hotter, am i right? By the way how long should I leave the test running? I sometimes leave it over night, but sometimes if I get too impatient I just leave it for 4 hours. Is that long enough? and what i discover, each time I increase the FSB by 10MHz, it will push the 3Dmark vantage CPU test score up about 500 to 600 points. cheers everyone :thumbs: |

| 785839 | 2009-06-27 13:11:00 | Nice going :thumbs: Similar methodology to what I used - except for my Q6600 I started at top multiplier because I wanted to know what safe ceiling I could reach. Then once I was stable, I re-enabled stepping - so that it clocks down when not required. Your other issue I think is that (for example) if you get to 450ish fsb on the board (big if) - then you'd be running @ just under 3.2. If you then try to increase from 7 to 8 or 9 (eg 3.6 or 4.0), you're almost guaranteed to need more voltage and your 'stable' settings go out the window. Have you thought about what clock you're trying to achieve? Because then you can work out best way to achieve it (fsb/multiplier). By going lowest multiplier - unless you stick to it (7), as soon as you jump up, stability is likely to be a major issue (as is heat, voltages etc). If I was you - and your target is say 3.6, then I'd be aiming for 400*9 (or 450*8 full time). If you get 400*9 stable, you can later re-enable stepping and run cooler when not required. Also - before you go too much further, I'd really think about an after-market cooler. You're currently @ 60C under load @ 2.5 (360*7) - so a 30% increase in speed is likely to jump that exponentially. FWIW (and I know every set-up is different) - under load (Prime95) @ 3 Ghz stable all my cores are ~ 55C (idle @ late 20's / early 30's). And the Q6600 is a toaster compared to your Duo. From your posts, it looks as though you want to do this properly - so I'd look at getting a decent cooler soon. |

| 785840 | 2009-06-27 21:47:00 | sweeeet Brooko, thanks for your advise. I dont really have a target, maybe 3.8 to 4GHz?? I am looking at something like this: www.trademe.co.nz should be sufficient.. and I won't buy it until I sell my lappy... I probably won't increase the multiplier until I got a new cooler. another thing to think about is to OC my memory, they are only good for 400MHz FSB, so once I go pass that I need to OC them to keep up as well... FSB at 380MHz, with prime95 running overnight, no warnings no errors. later in the day will do a benchmark test using 3dmark vantage again, then increase FSB to 390MHz. downloaded rivatuner, getting ready to OC my GPU. :) cheers guys :thumbs: |

| 785841 | 2009-06-28 01:38:00 | !!! at 380MHz the 3dmark vantage score dropped around 200 point when compared to the FSB at 370MHz!! what is going on here?? | powerover (12121) | ||
| 785842 | 2009-06-28 07:03:00 | Once you get into higher overclocks you need to start overclocking the memory to keep up. When you switched from 370 to 380 did you have to drop your memory speed? To try keep the memory speed up increase the voltage on that to 2.1 and set the timings to looser than standard and see if it'll let you ramp the mhz some more Can you give a link to your ram or some more specs? |

| 785843 | 2009-06-28 07:42:00 | umm, thanks ScreaminGherkin. here is a link to my ram: www.playtech.co.nz the speed of my ram and the FSB is unlinked, I set that in the chipset setting, they are actually running at 760MHz I think. I had the FSB set to 390MHz and was going to do the prime95 torture test again, then it failed to recover from sleep (gave me blue screen). So now I dropped it back to 370MHz (380MHz gave me a lower CPU score on 3dmark), will start to increase mulitplier soon... cheers |

| 785844 | 2009-06-28 10:00:00 | With my nvidia board (which is only a 650i sli) it's much faster and more stable when the ram is linked to the fsb. With that ram set the voltage to 2.1 and the timings to 5-5-5-15 and it should clock to about 1000. Also the nvidia chipsets are known for running rather hot so keep an eye on it's tempereatures if you can and perhaps some additional cooling over the northbridge. |

| 785845 | 2009-06-28 10:17:00 | ok..thanks for the advice screaminGherkin.. forgive me for my silly question, but where is the northbridge? in the mobo manual they only mentioned NVIDIA SPP (with active fan) and NVIDIA MCP (with active fan), which one is which??? I will try your recommendation once I find an empty CD so I can burn the ISO image of memtest86 on it to test my memory.. :) cheers |
