Do I buy PC6400 or PC8500???

post #1 of 13
Thread Starter 
How come I never really read about people buying DDR2 PC8500? Is it due to the limitations of the motherboard or that they are too expensive .... or a third reason?

As I haven't decided on a mobo yet I can't really decide on whether to get the 800 MHz or the 1066MHz. All the recommendations I read about are for the 800 MHz, so I was wondering if that's what I should be looking for?

I was planning on going with a P35 board but was wondering if it would be too difficult to find one that allows for PC8500 RAM?

Any recommendations/suggestions/opinions???

Cheers.
Anders

A lot of PC8500 RAM timings and voltages can be matched on PC6400 RAM overclocked, so if you're aiming for those sort of speeds, you can buy some good PC6400 and overclock it. If you get the PC8500 RAM you can get even higher clocks.

Sometimes* , because they have a 190$ rebate !!!!!!!
Other wise stick with a nice set of highly overclock-able 6400 ram.


*It's frustrating though because they require more voltage, so clearing the cmos becomes even more of a chore because you need some back up ram.

Don't you get a much higher overclock % when buying good PC6400 than you'd acheive from PC-8500?

6400= 400*2=800mhz 8500= 533*2=1066mhz so if you get a board tha supports 800mhz and you oc it to the point of where (you are using 8500) you actually oc is the standard for the 8500 ram it makes for a more stable oc and still leave room to oc the ram past factory setting to get high oc if i am correct

If you run "Linked > Sync Mode" (1:1) you don't even overclock PC6400 ram until you hit 1601Mhz FSB

And in most cases people go for the easy 1600fsb anyway and stop there.

From what i see PC8500 a lot of the time is just overclocked PC6400 unless it has tighter timings or uses less voltage then it's higher binned.

He's right, chip makers don't make IC's over 400Mhz (well in DDR2 anyway, that is changing with the DDR3). The stick makers use good binned IC's and rate them higher but it's still a 400Mhz IC certified by the stick manufacturer to run at an overclocked rate.
