Watercooling w/ Newcastle or Clawhammer CG?

[acivick]

I'm curious what you guys think. Here's the choices for OCing:

1. Clawhammer CG: Has full 1MB cache and can theoretically clock as high as the Newcastle cores

2. Newcastle: Half the cache, but with higher multiplier to achieve faster clocks given same FSB as Clawhammer.


Now the seemingly obvious choice is to go with the Clawhammer due to the extra cache, but due to the need of the higher FSB to achieve the equivilant clock, it may tax other components of the system (such as RAM)

Assumptions:
1:1 ratio is aim for the FSB/Memory clock
Watercooling will (hopefully) eliminate temp restraint for both
RAM capable of 250-260 MHz memory clock

Clawhammer. my memory does fast timing past DDR 500 fine and you can always adjust FID to match memory. You can oc for mhz but you can't add cache. Besides, my MB does past 290FSB fine so least of my worry is the limitation on FSB... (3.4 Clawhammer here... doubt I will get 50% even on phase cooling)

when u say ur ram does 260 is that what u put ur fsb to say from 200 and ur overclocked from 200 to 260???

Basically saying the ram is rated for 250 (say it was a Corsair XMS4000 or Kingston HyperX PC4000, for instance) but you could probably comfortably clock it up to 260, maybe even higher with more voltage and you would set the FSB to that speed. Perhaps an added assumption would be that the MB can handle any FSB to 300.

I would go for Clawhammer

i'm gonna say newcastle

and fsb's don't exist on A64's... it's called HT

ADA3000AEP4AX
CBAEC 0426UPMW

2.6 Ghz, HTT=260, mem 166 = 215.

Havn't seen to many claws doing this. Probelm is they are crappy stepping made a long time ago...maybe the 3700 is the way to go$$$

oh and good luck finding mem 260+mhz stable in a64 boards... I hav'nt seen it. Has anyone? What I have seen is almost all new NC can OC 2.5+ on air making the clawhammer not so attractive when they have difficulty hitting 2.4.

I'm using FSB loosely here because many people don't realize that important fact. But you are 100% correct.

But then again, probably anyone who would be able to intellegently comment on this topic would know this piece of info, so yeah it's HTT 🙂
