nForce2 & DDR500

[TheMASK]

If i buy DDR500 RAM, wud it be possible to run my Barton 2500+ at 400FSB and RAM at DDR500 on my A7N8X Dlx 2.0?

Why?

It would help absolutly nothing, a little math...

Max bandwith of an AXP cpu with 200mhz bus
3200mb/s
max bandwith of 64 bit (single channel) pc3200
3200mb/s
max bandwith of 128 bit (dual channel) pc3200
6400mb/s
max bandwith of 128 bit (dual channel) pc4000
8000mb/s

Can you say overkill? Just get some pc3200. My guess is that performance would actually be worse (with pc4000) because if you want to run pc4000 speeds you will need a memory divider. Also don't count on overclocking your fsb to 250mhz, because without exotic cooling i dont think the nforce2 can take it. But if you must know it will work with a 5/4 mem to fsb ratio.

With a 400MHz/500MHz FSB/MCLK ratio you'll take a performance hit because of latency. Sync FSB/MCLK is highly recommended for the nforce2 chipset.

Why not run the DDR500 at 400, then overclock from there?

(u cud skip reading thru the following 2 paragraphs and direclty go down to the text in <b>BOLD</b>)

hmmm... i have done my math. I am stuck with DDR333 for the time being. So i planned to buy DDR500 now as that is the highest speed available here. I know there wont be much performance gain with this RAM, b'coz my motherboard does not like more than 210FSB. So, I cud run the CPU (a Barton 2500+) in sync with the memory at lower latency (the DDR500 Kingston Hyper-X is rated 3-4-4-8). I am planning to run it at something like 2-2-2-5 at DDR400/DDR420 speed (in sync with CPU FSB, as much as my mobo wud allow me).

The reason i opted for DDR500 over DDR400 is, i plan to buy a <font color=blue>P4<b>C</b></font color=blue> with a good mobo in about 6-8 months time (by then the prices of P4 2.6/2.8<b>C</b> wud have come down, hopefully) and overclock the heck out of that CPU. I dont want to invest in a good set of memory sticks again then. Hence i am getting DDR500 now.

<b>I cud run my CPU at 333FSB and RAM at DDR400 by suitably tweaking the BIOS settings (Memory FSB = 120% of CPU FSB). So i was wondering wud it be possible to run the RAM at 120-125% of CPU FSB even when the CPU FSB is 200, which wud be runnning my RAM at DDR500. I just wanted to know wud this setting work? wud the nFOrce2 take that much load with the stock north Bridge passive heat sink? Wud there be any appreciable performance gain?</b>

i guess my question was incomplete... read the above post, that makes sense now

yep, thts what i plan. but read my reply to piii_man. it makes more sense.

[pIII_Man]

I answered all your questions in my first post, i dont see what the problem is?

[TheMASK]

yup, u did. my reply to you shud have been my very first post. since my first post was vague, i put in the questions again.

Tnx a ton.

[pIII_Man]

ok, i am still confused by your posts but whatever...

Why do you advertise the THG irc channel but i never see you there?
