Stable E8400 OC - stock voltages

[Outer Marker]

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.
Thx for post.

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.

Thanks for the help.

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

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.

[ky0t0]

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.
