all DDR 400 is slower that DDR 333

Well... the ddr400 memory capsels aren't slower than the ddr333, but the current motherboards that support ddr400 through the KT400 chipset perform worse then the motherboards with KT333 chipset.

All (except gigabytes)mobo work faster with DDR 333 with KT333 or KT400.Sis and via will not back uop DDR 400 any more so.

Now what to do??

It depends on what chipset you are using, and for which processor.
but either way if you can run it at cas2 then you will get better performance.
On AMD chipsets its often better run PC2700 on hard mem timings instead.

Sambsung chips are known to overclock well, so its possible that you could run that cas3 at cas2 right outta the box.

If Slvr_phoenix read this thread, he'd be having nightmares at night. Please people, stop reminding us of the infamous "3" in CAS history! :wink:

Cas 2.5 ddr400 runs at about the same speed as cas 2 ddr333. In theory case 3 will run slower than ddr333, likely it will run at ddr266 speeds.

**ROFL** Luckily my mobo and BIOS both don't even give an option for CAS timings, so I'm not contstantly reminded visually of the horrible latency of my PC66-spec northbridge.

You just wait though. One of these days I'm going to actually have the money to get a P4 and 32ns PC1066 and replace that old Celeron 500 box! Hopefully by then I'll be able to get a gigabit network, USB2, firewire, AGP 8x, and serial ATA all built into the motherboard. ;) 

(I know, maybe I'll go AMD if they can ever pull their head out of their arse, but I still have qualms about VIA, so I'd probably have to kill my price/performance ratio by using an nForce2 mobo and then, what's the point?)

CAS2 is, of course, faster. ... In theory. If you're using a VIA motherboard though, DDR400 is a pretty pointless investment.

If it's a true Samsung stick, then you'll probably be able to run it at a better CAS than it's rated at. If it's just Samsung chips on another company's stick or rebranded Samsung, then chances are at best it will only perform as advertised.

IT´s!!... Not true. Cas3 pc3200 is not slower than pc2700 cas 2.5. Actually there isn´t much difference between the cas level with these high speed memory. Although yoou get 10% performance boost with pc2100 it´s much less with pc2700 and it´s not enough, to reach the remaining mhz up to 400mhz. There is actually only one chipset that can run with pc3200 that´s the new Nforce2 and theres is some of the Sis648 which runs stable at 400mhz but with only one 256mb block. Corsair pc3200XMS is the only known to me that runs stable on mobos who unoficially supports pc3200(or 355mhz), the reason is of course the have the legendary Samsung CTL pc2700 underneath the heatspreaders.

You can get PC3200 Cas2 from www.newegg.com which with the 648 chipset is faster than PC2700. The only board I know of that can support 2 sticks (officially) or three sticks (unofficially) of the stuff is the Gigabyt GA-8SG667, and the only memory brand I've see it tested working with three sticks mounted is Corsair.

The Gigabyte GA-8SG667 can run two sticks officially, and was tested successfuly with three by Anandtech. I hate having to police these forums.

I´m using a board from DFI (PE21-EL) and 256MB PC3200 from Samsung and it´s working fine with CL2.0. According to DFI it is supposed to be able to handle 3 sticks from Samsung but I have yet to test this. Have to recomend DFI since I got really good support from them.

The way I look at it:

You buy a 120hp tractor, and run it at 98% for the entire season. 10,000 hours.
That tractor is hammered. Completely.

You pay out the ass for a 280hp tractor, and run it at 50% the entire season. 10,000 hours.
Still in very good shape. Good for another season of disking and sewing. Gotta grease the zirts, and swap out the oil, but it's still a good tractor.


Don't get the minimum. Even name brand minimum. Move up to the next level. Get the cheapest PC3200 you can find, and run it at 166mhz. Or buy PC3500, and run it at 200mhz.

It's not the memory that's slow. The memory is performing as designed. It's not the processor that performing slow. It's working as designed.

It's VIA. KT400 just doesn't work as designed. Or touted. It's really a KT333 chipset, with some neat glitter paint on the cheeks, a clit ring, and some nipple rings.

Which can actually be very kinky if you use it properly.

Or you can be like me and run your DDR333 at DDR355.
