best 1333 fsb mb and 1066 ram

nforce 650i SLI and 680i SLI motherboards supports 1333fsb chips, u dont need 1066 ddr memory as 2 sticks of 667 or 800 in dual channel will be fine as u can get a gig for £22(UK price) $30(US price), and u dont need to buy ddr2-1066 or ddr3 memory

u can get a 2gig ddr2-667 kit for around $60-70 on newegg

buying ddr2-800 dual kit will still give u headroom if u want to overclock your cpu from 266/333(1066/1333) to 400mhz(1600)

i have an ASUS P5N-E SLI mobo with 2x 512meg ddr2-533 ram and soon i will have a Core2 Quad Q6600 chip and that cost me peanuts

so with ddr2 800 ram the max fsb that would make sense would be 400 right?

fsb 400. so thats cranked up to fsb 1600 for advertising purposes or cause it multiplies it by 4.

i'm seriously still confused at how this works. i get that the clock of a cpu is the fsb times a multiplier. 266 x 9 is common on the c2d's. or 266 x10.

so if i pushed the fsb up to 400, itd be a 3.6 ghz processor now. and 400 fsb is the farthest youd want to go with ddr2 800. but with ddr2 1066 you could push the fsb up to 533 right? and then the cpu would be like 4.8 ghz! wouldnt it?

is that too hard because of cooling? or because you need a really expenive board?

if i use ddr2 800 and push fsb to 400 then the fsb ram ratio is 1:1 right? but then does it matter if i use a 1066 fsb cpu or a 1333 fsb cpu?

thats confusing to me

true, but the cpu does 4 instructions per clock so when the base clock is 266 it would effective do 1066 as it would do with a single instruction and the memory only do 2 instructions per clock (hence ddr) but memory speed is half of the cpu speed so thats why u need 2 sticks of them, and now memory speeds are getting faster


your on the right track


some boards can do 500mhz or more but its difficult and also u need expensive cooling to acheive that speeds, but about 400 is a decent overclock, but i believe 3.0Ghz+ is attainable on stock cooler


yeah thats right, and it doesnt matter if u use a 1066 or 1333 fsb chips and if u have 2 sticks of ddr2-800 which makes it 1600 effective and gives u room to overclock the cpu

dont forget u need to divide the fsb by 4 to get the actual core speed and so the memory would only need to be half the fsb but u need 2 sticks to run in dual channel

in my system which is being upgraded over the months, im running a p4 on a 800fsb, and i had 2 sticks of ddr-400 in dual channel effectively making it 800, but now ive changed motherboard and memory am running 2x ddr2-533 making it 1066 which in turn would be enough when i get a core2 quad cpu 1066fsb, and possibly get some new memory at 667 or 800

i hope that helps u

ok thats helpful. so if the fsb is pushed up to 400 ddr2 800 makes the most sense. but since i do plan on getting a good cpu heatsink fan thingy, then maybe i could push it up a bit more. with ddr2 1066 the ideal is 533 fsb, but if say i only got to 475 fsb, would that be a negative over ddr2 800 w/ 400 fsb or just not as much of a benefit as ddr2 1066 w/ 533 fsb?

so lets say i get ddr2 1066. its not much more expensive now and itd give me more room to play. so it looks like all the mb's id consider are fsb 1066/1333 so that part doesnt matter much. so then whats the difference between getting a cpu w/ 1066 fsb and one with 1333? would they both be able to achieve the same overclock? would one oc more than the other? im thinking that if, say, i was to hypothetically get my fsb up to 500, which would be close to optimal for my memory, then theyd both get cranked up to fsb 2000, right? but would one require more cooling? im assuming that the fsb 1333 chips would be even easier to oc.

does quad affect any of this? im pretty much decided on a q6600 on july 22ish.

lmao. whats best about all of this is im really worrying way too much. im sitting on an almost 2 yr old hp with an amd 3800 1 gig of ddr400 with cas 3 i think and a mb thats probably pretty crappy. whatever i buy is going to be a colossal improvement. but i want to get it perfect for me so im being anal.

thanks!

i dont think u can overclock that far without it being unstable. ive never overclock my chip and i dont plan on doing it to my new quad core chip

also having a good heatsink will make the chip run slightly cooler maybe 5-10 degrees, so u can overclock it back to its normal heat, say if the chip is 60 degrees with intel cooler, and 50 degrees with a better cooler, then u can overclock it so that it reaches 60 degrees


i dont suppose so, if the 1333fsb chips are still on 65nano, then u have little headroom but maybe possible with a 45nano chips. i dont know, only time will tell


same here as im getting mine as soon as it happens, and i dont think a quad core would affect much, but may not overclock as well as the dual core ie using more power and being more hotter

i would say overclock it with a good heatsink to 3.0Ghz from 2.66Ghz, so thats 300Mhz core speed(1200) up from 266Mhz(1066), well within ddr2-800 dual channel(1600)

If you do get a Q6600, there's not need to get anything faster than DDR2-800 because there's no way you're getting the Q6600 to 400 Mhz FSB without using water cooling at the very least, and if you're using water cooling, you can afford the faster RAM.

further to the reply, ive heard people here on tg forums, some successfully overclock their cpu's, others have problems, so your best bet is clock it to say 300Mhz(1200) with 400Mhz(1600) at a push but may have stability issues, 500(2000) would be overkill unless u bolt a freezer on it!

having a very good heatsink and clock it to 300Mhz(1200), u would be fine, and the chip will be at its recommended temp and still have ddr2-800 memory in dual channel

ok well i need a mb. if i got a p35 i think id get the gigabyte ga-p35c-ds3r. not too expensive with tons of room for future upgrades. i mean ddr3 capability and 45nm cpu compatibility, i could have that mb for a while. or i love the evga 650i ultra. or some not too expensive 680i.

ive decided on some nice ddr2 800 gskills that have great reviews, but i still need my board.

relatively easy question you all have seem to confused and bogulated, non the less here are your answers.

You odviously want to upgrade to penryn when its availble, so you waqnt a P35 board i recoomend the gigabytes varient on the DS3, you find on new egg or scan (UK) its P35 DS3 and should provide the same OC'ing the eariler DS3 could.

Secondly you want FAST RAM so go for the dominator the stuff great its as faster as you want it to be with extra OC room. however you might just as well go for the full hog and get DDR3 from corsair

hope this helps

well i guess thats my motherboard then. but the dominators are a bit too expensive, and thats the lower models, the better ones are way too much money. those gskills are ddr2 800 with timings of 4-4-3-5 and they have the better d9 chips in them or w/e. they're reviewed very well for price/performance ratio. and they're 100 bucks. so I guess i got it...

after july 22:
q6600
gigabyte ga-p35c-ds3r
2 gig gskill f2-6400cl4d-2gbhk
apevia x-pleasure black case


lets see if this configuration is the same when july 22 rolls around lol.

thanks to all
