Hey i recently called OCZ and had an interesting chat with the tech. support. I first thought going into the conversation, to get your ram at its speed in my case ddr2-800 4-4-4-12 2.1 V, then just bump up on the mhz a few to like 2.6 on an e6420 and thats an oc!. He however, added an extra step. He said that if you were to get the 2.13 to 2.6, you would have to first bump your ram MHZ down to 667, then when you get the FSB to 325 (2.6) The ram will go back up to a bit over 800 MHZ. Is he correct? Should i do this? Do i have to enable some feature to make sure the ram goes back to 800 a bit over when i bump up the CPU FSB? HELP

What tech said for right. 8O (usually they are wrong). This should give you 2.6Ghz on the CPU. Btw what is your motherboard?

965 P ds3. So they are right?

Computers, RAM, and motherboards all work using Magic. That's it.

Yes he was right. You do need to lower the RAM speed so that when you raise the fsb, the RAM speed increases back to its rated speed.

that sounds about right.

Yup yup, it has everything to do with multipliers :)

never argue with jack, and, yes- :twisted:

ah ty, but do u have to enable something to make sure the RAM gets Oc'd back to 805 as well?

No that is done when you increase the fsb.

What you could do to see this effect for yourself is too install cpu-z then decrease the ram speed and increase the fsb a little. Then boot into windows and check the ram speed in cpu-z. Then do the same again and you should see the ram speed increasing each time you increase the fsb. You could even do some of the calculations that Jack mentioned.

wait, so there is no manual OCn option for the DS3?
May 4, 2007 2:39:07 AM

Yes there is. You increase the fsb...manually. Which in turn increases the speed of the ram due to the RAM divider. I'm pretty sure its the fsb that provides the base frequency, everything else is a multiple or ratio of that.

Nope.. none.. it's all done by the magiks in the air
