6400 conroe with twinx 800mhz cas5

[markymoo]

I ordered a 6400 conroe (2.1ghz 266mhz x8 multiplier) and
2gb (2x1gb) corsair twinx xms2 ddr2 6400 800 mhz CAS 5-5-5-12
I went for the cas5 because cas4 was out of stock and i couldnt wait plus if they still run at 800 like the cas4 they still quality. my thoughts were they can be overclocked still if im running them on the p5b and save some money in the process. I understand the timings between them are marginal. If you overclock the cas4 they end up as cas5 timings anyway. This made sense to me. Am i right? Or is the cas4 better overclockers outright.

I'm trying to understand the best overclock before i get my conroe. I'm aiming for say 400 or even 500 fsb. I realise if i flash with the 507 bios. Theres potential...
Can i do it with this memory? Its cas 5. I have giant noctua-nu12 cooler so im hoping for good results. I want to run the memory in dual configuration mode. Is the ram timings different when im running in dual? I know i get the best o/c running the memory at 1:1 but what speed do i run the memory at? Is it better i run the fsb at 400, 800 , 533 > Default voltage is 2.1 so i take it upto 2.3 but i hear not good idea to take it past 2.3 Whats the possible configs to maximize fsb to the limit. I understand you can drop the multiplier now but if it increases the fsb but the overall ghz drops that cant be good can it.

Say i set fsb to 400 do i set memory to 400 or 533 or 800

Say i set fsb to 500 do i set memory to 400 or 533 or 800


Many Thanks

Those Corsair Twinx ddr2 800 cas5 kits overclock pretty decently, I've seen a lotta peeps doing over 450mhz with them, more like 470-480mhz. With the E6400 you got, 8x450=3.6ghz already so if your motherboard allows that kinda FSB then you're in good shape with that combo.

3.6ghz is a very good oc already and some don't even get up to that on a sustainable vcore with good air cooling, so you got some decent headroom with that ram.

yes thanks. if i can hit 3.6gig i be happy. If my 800 memory can really hit say 900-950
theres a chance.

so 3.6 seems my limit then on my good aircooler.

so is it possible to set the ram at manual setting of 266? so it exactly equal to the cpu. i guess this give it the maximum potential to oc

 

[silentvois]

I would say 450mhz on the memory to be safe.
3.6ghz on the cpu if you get a good batch and a permitting motherboard.

You know, technically the 6400 isn't a Conroe lol. The E6400 might be a Core 2 Duo, but it's an Allendale

 

[markymoo]

once i overclock it be faster than a default 4mb conroe so lets say it is lol

can i reach 500fsb with overclocked 800mhz ddr2 memory?

this guy did but used GSKILL DDR2 1000 HZ to do it and excessive 1.65 voltage

Those gskill hz kits can do 1000 with volts, so can the teamgroup kits but would you really wanna spend more on ram when what you have already provides you with probably more than you need?

If you're building a computer to use then don't spend that premium for high performance ram, people only buy that kinda stuff to squeeze every bit outta their setup to bench and showoff to fill a deficiency in life.

yes my memory fine, just want to maximize what i got. im not changing the memory

i settle for 3.6 , it will fly if i can.

going to use AS5 to cool the northbridge
