Can Corsair PC2400 do 333Mhz CL2?

Can Corsair PC2400 do 333Mhz (PC2700) CL2?

 

[Dunbar]

That's about 166Mhz and it can do that, most likely your PCI components won't like it though.

I read in a review that it could do 166FSB @ CAS 2, and over 180FSB @ CAS 3...

A stick of Crucial PC2100 was used in the same comparison and that could reach 161FSB @ CAS 2...not bad!!

My K7S5a has a 1/5 pci divider.

 

[igowerf]

180?! How did they even test that?

 

[Dunbar]

Most likely they have a 1/5 divider like you, as long as the ram can do it it's just a matter of unlocking the multiplier on the CPU.

So do you think just about any new TBird can hit such a high fsb? I'd really like for my 1.4 to run on a 166 fsb is possible.

EDIT: I'd lower the multiplier first of course.

The cpu doesn't "hit the high fsb", your memory/fsb bus does. So to answer that question, NO I don't think many can. Not many people have had success above 160FSB on a DDR motherboard. However on my KK266-R (KT133a) I can do 167FSB.

K7S5A has 133/166, and 166/166 fsb/mem settings in a BIOS version (dunno which).

I'm confused, assuming you have a 1/5 divider and your memory can hack it, all PCI components are still in spec (dunno 'bout AGP 'tho) so what would be the problem? Im a couple of generations behind (P3-700 @ 933, Asus CUSL2) but will be upgrading soon so I need an update

 

[igowerf]

Hmm... I always thought that how high your fsb can go is also dependent on the processor. My friend's Duron 750 on his A7V133 wouldn't go past a 111 fsb even if he dropped the multiplier to 4.

True, but an increase in fsb obviously affects the speed the processor is running (assuming you don't lower the multiplier). I'm sure that's what he meant.

Your fsb is going to depend on what your motherboard allows. Whether your processor can handle the increase is a different story.

Well, my motherboard supports a 166fsb with a 1/5 PCI divider. Everything will run nicely in spec (except the processor I guess). The overclock from 10.5x133 to 8.5x166 is still not guaranteed because the processor may not be stable running on a 166 fsb right? This is assuming that I get some Corsair PC2400.
