overclocking question

post #1 of 14
Thread Starter 
ok, i have a p4 prescott 478 @3 ghz. i have a 15x multiplier and 1 gig (2 sticks) of pc2700 memory @ 2.5-3-3-7. so, since my memory is rated at 166 mhz, and my FSB is 200mhz, do i loosen the timings on the memory to achieve that 1:1 ratio?

help is appreciated, thanks ahead of time

Yes, since it's rated at PC-2700 with the timings of 2.5-3-3-7 your going to have to loosen them up to 3-4-4-8 or around there to get them to run 1:1

there should be a setting to set the ratio to 1:1, do that, and yes lock your agp/pci bus to 66/33, or it can cause instability or possibly damage you hardware..

if your just starting to overclock for the first time i would suggest reading this faq... and just satrs slow keeping a cloase eye on temps.... other than that good luck and if theres any more questions ask!

OH and one more thing... after you have oced to where your happy and it seems stable, run Prime95 for atleast 8-12 hrs and if it passes without any problems then you have a stable OC

no, this wont raise the temperature of your CPU, just the temp of your memory (don't be conserned)

I don't think your motherboard has that option
The micro ATX boards with the SIS chipsets arn't very good overclockers to start out with. I would invest in a new motherboard if you want to get a decent OC. I mean if you run your memory on a devider with this current setup, you might squeeze 3.2GHz or 3.3, but not much. I would put a new motherboard on top of the list for future upgrades.

oh snap o well i didnt set my mind on oc'ing to much, just fixed on learning, you know? thanks for the help. sadly, upgrading the motherboard isnt really in question right now because of money lol. im jsut a teeen maybe it will be an option once i get a job. since my current card is agp, and i'd want a pci-e board, id have to buy a new card, and maybe even an AMD cpu :-P, and i think a new PSU because isnt their a specific psu for pcie?
