Ideal system?

[hurrikaane]

From all my research it seems like this would be, *on paper* the ideal system:

2.6c
Mushkin L2 3500 @ 2 3 2 6
Abit IC7 or ASUS P4C800
Divider 5:4
Result: FSB 270mhz CPU 3500mhz

This system basically has it all: exceptional CPU/FSB speed as well as tight memory timings. Would however need a new HSF.

The question is: how many P4 chips can be pushed that high? Would water cooling be necessary?

For money you are right but to be true the ideal system would be running 1:1 with memory insynch with fsb....

in this instance though

2.8c@250fsb=3500mhz
pc4000 at 500mhz ddr

the resulting timings may be so poor since they would likely be cas3,4,4,8 or something.....


NOt that many of the chips will hit 3.5ghz...many still don't get much over 3.3ghz...I have seen a few 3.5-3.6ghz (air cooled) range chips and they were mostly 2.8's or a handful of week21 or later 2.6c's....

Watercooled I have seen many 3.6-3.9ghz range.....

Like you said, the memory timings on synch OC'd systems are poor. And in your example, the FSB is only at 250mhz, whereas 270 is quite achievable at 5:4 at tight mem timings.

One of these, fully decked out, running about a hundred Seti@Home clients...


Ideal system for what?

 

[hurrikaane]

I personally do a lot of photo editing (Photoshop) and gaming. So for me an ideal system would handle those two jobs flawlessly.

but if we are talking bandwidth then eventhough the fsb is 270 or 1080 with a theoretical bandwidth of near 8.8gb/sec will not be met by the 432mhz or pc3500 ram in Dc delivering 7gb/sec....So you really are not taking advnatage of the greater system bus especially when overall clockspeed in both examples would be the same at 3500mhz....

At 100fsb the bandwidth would be theoretically 8.0gb/sec with the ram theoretically delivering it. The potential is for 1gb/s of bandwidth. At same clockspeed this may be neglible cause of the low cas timings of current pc4000 dimms, but I think most wil agree if same clockspeed is achieved 1:1 insynch memory may always be the more ideal situation.
