pc5400 better than pc6400?

post #1 of 11
Thread Starter 
Something I am curious of...

I've played around quite a bit with my 5400C4 xms@'s and I don't quite understand the improvement I would get from getting some 6400 ram. I hear a lot about people almost hitting 1000Mhz with their 6400, almost... Thus far, I've hit 980 at 5-6-6-17 timings. Although the timings may not be that great, what exactly would I expect from a 6400 cas5 kit??? Thank you to all who post advice.

What I'm trying to get from this is whether I should even bother buying 6400 ram... Thanks...

Is it your ram slowing your overclock down or what? If it isn't your ram then there is no point, if it is your ram then you could if you feel the need and sell your current, it shouldn't cost you much

Are you sure that you've hit DDR2 980 with the 675 kit? That's a 490mhz which originally are 333mhz, a 157mhz overclock. Sure about that one? And is it stable?

I got the same RAM as you and the highest they can get is 442mhz with 4-4-4-8 timings and 2.20v.

you don't have the same ram, mine are matched 512's, not 1024's...

Well, I guess I'd need to try with those timings then, I did try the 5-5-5-12 at 1000mhz but no luck, I didn't try anything below that, so the only two I tried were 442 and then I tried the full 500mhz and no luck but I guess maybe mine could do the 490 as well.

Wish I had an E6300 to test them on a 1:1, I don't really like to change the ratio on my E6600.

I will try a 245mhz with a 1:2 ratio on my P5WD2-Premium and see if that is stable, and it should be DDR2 900 speeds with that ratio. I'll do some time. I'm not trying 5-5-5- though, I'll try a 5-4-4-9 and see what happens.
