  • Stable E8400 OC - stock voltages

    Just posting this in case it helps anybody out there with a similar configuration. This represents a 20% overclock on stock voltages for the E8400 E0 stepping. Full credit goes to LSD for the original template, I just made it a tad easier to read (I'm anal like that ). Perhaps it will help some noobs like I still am

    Looks good, thanks for posting for others!!

    tRRD and tRTP of 3 should work fine for you, just incase you were not done tinkering

      How did you figure out the System Memory Multiplier to be 2.66D?

      My memory is DDR2 800 (PC2 6400) 4-5-4-11 2.1V - 2.2V. I am using the GA-EP45-UD3P and the E8400.

        Nice ..hmm so D will work on 333mhz cpus. I might experiment again tomorrow,its not like im going to blow anything up..I hope.
        399/401 fsb wouldnt be much use to me .. grr low multiplier but maybe ill get some good action.

          Well for me it wasn't so much of figuring it out as what would work with my memory. D represents the 400 Strap. Since I have 1066 MHz memory, 2.66 x 401FSB =1069 memory speed. It fits nicely. Anything less than 2.66D would have underclocked my memory. Not saying that I couldn't have done that, but I just figured 400 strap would be great for some nice loose timings, nothing hard core, just a great overclock with stock voltages. Since you have 800 Mhz memory, I think you could do the 2.00D memory multiplier at 401 FSB quite famously. At that point you would have a 1:1 FSB:DRAM ratio which some people seem to love.

              Yes, you can use 400/D multi's anytime you wish, you just need to find the correct MCH Voltage and tRD Setting to allow it to run, same applies with 333/B Multi's

                Re: Stable E8400 OC - stock voltages

                Hi everyone, i've read the bios settings for this system, and they seem great, can I use those same settings on my system?

                The difference, is that my system has an E8500 Processor, my motherboard is the EP45-UD3P, and memory is the corsair dominator 1066.

                Thank's in advance.

                Cheers

                  Absolutely. You should be able to use these with the same success as I did. If not, they'll give you a very close starting point. Can you post a link to your exact memory type? It would help for us to see the rated memory timings and voltages in the specs to make sure they will work well.

                    Thanks for the fast responce.

                    Ok, by memory modules appear on CPU-Z as, Corsair Dominator cm2x2048-8500c5d, i can't find a correct link with this reference, but they where bought as a 2x2 Gb kit, i think the link is this: http://www.corsair.com/_datasheets/T...96-8500C5D.pdf (from the official web page of corsair).

                    I hope it helps.

                    Thanks again.

                      Re: Stable E8400 OC - stock voltages

                      OK, the only change I would make to the above settings would be to run your memory DRAM volatge at 2.1V per the specs Like this:

                      Code:
                      DRAM
                      DRAM Voltage............1.800V.........: 2.100V
                      My memory says 2.0~2.1 so I got lucky by using the low end at 2.0V. From the link you sent me, it seems that your Corsair wants 2.1V so best set it to the specifications. That will give you the stability you seek.

                        ok, thanks, my memory is set on bios with that voltage.

                        I'll try that bios settings, and hope everything goes fine with me.

                        I'll be back with results.

                            This is great. I'm just starting to look into OC'ing and you've given us a great starting point. Only problem is I'm not certain if you have the same HSF so your settings may not work for me!

                              I have the Arctic Cooler Pro 7. However, this should not matter one bit. My point was that the settings I gave should result in a stable overclock at stock voltages, so no additional heat should be generated. A stock Intel cooler will work fine, even if you had to bump a few settings up a bit.

                              With the rig in your signature, you should be in fine shape!
