| 517246 | 2007-01-18 04:56:00 | As seen in my signature, my cheapo Auspis DDR2533 couldn't handle speeds above 575MHz when I overclock my CPU to 214MHz FSB. Can anyone recommend me a good RAM? |

You've got a fairly hot computer, why saddle it with things that may not work or worse, cripple what you've already got? Try this site: www.crucial.com and let them scan for you..it's free and you can print it out for future reference and buying happiness. |

| 517248 | 2007-01-18 08:55:00 | Have you loosened the timings? cause NO RAM at stock timings can go to a large OC, you need to play with the timings, if you have maxed them out (highly unlikely) [I am running my Legend (cheap) RAM (DDR400) at DDR490, that is with a little tweaking of timings, with more tweaks I can probably get DDR500, but I am happy cause everything is opmimal ATM] You will need to put in a RAM:FSB divider and then you are able to ramp up the CPU more, but the RAM will be lowered till you OC the FSB again, but atleast you can run the CPU harder. But as SJ said... "good", "cheap" and "overclocking" do not go togrether... Just my :2cents: |

So is all I need to do is loosen the timing of my memory, than let its speed overclock with the FSB? Mine is set at 4-4-4-11. Will 5-5-5-12 let me reach up to 600MHz? Indeed, motorbyclist, I mean an overclocking RAM good for its price. |

| 517251 | 2007-01-18 13:01:00 | Wait....so if I wanted to have my FSB on 233...meaning my CPU will be at 3495MHz (233x15), and I still want my RAM to run at 533MHz, what would the ratio be for 233/266? I'm not getting the hang of this ratio thing. How do I set this ratio? |

| 517252 | 2007-01-18 13:47:00 | twinmos is not overpriced and does o/c pretty well | drcspy (146) | ||
| 517253 | 2007-01-18 18:52:00 | How do I set this ratio? I can't tell you cause I don't have that mobo... there should be an option in the BIOS under the RAM config section that should say something to the effect of DRAM:FSB,CPU etc and will be 1:1 ATM, I am running cheap stuff on a 270 FSB with a 10x multi (2.7 GHz CPU) and running a DRAM:FSB ratio of 11:12 (11 clocks of the DRAM for every 12 of the FSB) giving me DDR491 at timings of 2.5-3-3-7 1T, now that is really quite good, cause those are the stock timings for DDR333 speeds!! and are tighter than DDR400! All I can really say about OCing is READ, go and troll overclocking forums such as http://forums.overclockers.co.nz/ and do Google searches, that is how I have learnt. Oh and it is also a very good idea to keep the HDD clear of any important data cause corruption is highly likely when overclocking. I will admit I know very little about Intel OCing cause I have never done it... but ask at OCers and Google Oh and one other thing... DO NOT be scared or surprised if you get any BSOD while OCing cause you are pushing something past its limits... |

LOL, are you sure its the RAM? You are working with an already hot chip there. Pentium D chip were slower than AMD dual core for a reason, they couldnt run at high speed. You have to take the RAM out of the question 1st by underclocking it, then increasing the FSB to find the max safe cpu overclock 1st, once that is established, take the cpu multiplier and decrease by at least 3, then wind up the FSB again to find max RAM speed. Once established, use RAM:FSB divider to set max OC |

| 517255 | 2007-01-18 22:08:00 | Nah, my Pentium D stays around the same temperature at 3.22GHz at 35-38 while idle and up to 50 under load. So I don't think overclocking it to 3.5GHz should hurt it. I read that it should be able to get up to 3.8GHz on stock cooling and voltage, but I'm noy gonna go there yet. My money is still needed somewhere else lol. Oh, and I can't underclock my RAM. My BIOS will only let me overclock it to 667. And I also can't change the CPU multiplier. It's locked. By Intel themselves. Now, I just need to find that ratio option in the BIOS..... |
