PC2-5300 worse for (stock) Conroe?

Great link, have been looking for an article about this for a while :) Sounds like u have to have to decide whether to buy cheap pc4200 and never overclock or buy more expensive pc5300 or pc6400 and overclock straight away to get the best out of it.
 
If you look in the offers section on the main pages, they're selling 2 gigs of G. Skill PC2-6400 RAM for £125 inc. VAT. Not a bad deal, so I snapped some up for my E6600. Admittedly, I was also ordering my case and graphics card at the same time, but that price is as much as you would pay for some PC2-5400 normally.

I prefer Corsair but im sure others will say G.Skill, personal preference really. Before i read the madshrimp article above i was going to get pc5300 as it was cheaper, now i want to go for the 4-4-4-12 Corsair stuff but dont want to spend £200 on memory! And im not sure how good the 5-5-5-15 stuff will be?
 
Yeah reading that link makes me think i will probably get the pc6400 5-5-5-15 stuff as it should still be faster than any pc5300 memory and allows for overclocking. And even though i usually prefer Corsair, the G. Skill RAM for £125 looks very tempting...
 
I'm still a little confused. So is it best to get the fastest memory you can afford and run a divider on it?.

If i bought say 6400 800mhz will the memory actually be running @ 800mhz? or does the divider actually underclock the memory to 533mhz?

If this is the case then when is memory not syncronised with the fsb!

Cheers.

It depends on the board but with my DS3 you can put the ram up to its stock speed or above without clocking the cpu if you want

I see, so I guess this would be unsyncronised. How much performance impact would there be not running syncronised?

What would be better:

4200DDR @ 533 sync.
5400DDR @ 667 no-sync
6400DDR @ 800 no-sync

Thanks.

I would go for the PC6400 it will be faster than the other 2 even though it will be out of sync
 
4200DDR (533) is faster than 5400DDR (667) due to the non sync of 5400DDR. But 6400DDR (800) is faster than both as it runs quicker and can make up for being non sync. Mind u when i say faster we are only talking very marginal amounts. So basically i would say if u are on a budget and dont want to overclock get some cheap 4200DDR, otherwise get 6400DDR.
 
In any case, couldn't the 5300 memory run in sync with a core 2 duo @ stock by making the speed of the memory lower i.e. @ 533MHz? I'm still confused by this stuff, but I thought if you weren't using a divider thingy (i.e. CPU to RAM ratio is 1:1?), whether you were using 4200, 5300 or 6400 memory, they would still run at 4200 speeds.

Yes, you could. You could if you wanted then increase the FSB to 333mhz to have the memory running at its rated speed, while keeping it synchronious (this would have course also overclock the CPU).
