bios update perhaps?

well it the same, just lower the CPU multiplier.
start from ddr2-667, just push the HTT way up with max vdimm.

Bro.. its AMD.. the ram clock is depend on the divider itself..
for example:

250FSBx10 = 2500Mhz - RAM = CPU/6 - 416Mhz(DDR832)
270FSBx9 = 2430Mhz - RAM = CPU/6 - 405Mhz(DDR810)
250FSBx10 =2500Mhz - RAM = CPU/5 - 500Mhz(DDR1000)

so wat i need to get my ram running DDR1000 is either my proc can reach 3000Mhz( which is nearly impossible ) or get the CPU/5 divider (which is i dunno how to get it )..

anyone with DDR667 with Biostar Tforce 570U can change the divider to CPU/5??? and yet still couldn't find any update for my bios..

The divider cannot be changed. It have to depends on ur multiplier and ur ram divider.

Refer to the first page diagram, for multiplier 10, u need 800 ram divider with 250 FSB to achieve 1000.

u cannot change the divider.. the best u can do with ur ram.. just tight the timing..

or u mean.. cannot set 800 divider when doing 250fsb?
maybe something wrong with the bios or the board itself limit it..

ya my bios got option for 800 divider but it limit me to my ram spec that is DDR667 looks like i need DDR800 ram to archived that.. lol

My mobo does not allow me to use DDR2-800 divider as well... kinda weird.

I have no problem using DDR2-800 divider on my previous UltraII-M2, with the same RAM.

same with mine too Kn9 ultra.cant use ddr800 divider..it will not boot at all.

guys..
try to raise the vdimm... and use 2T CR first.. loose the timing a little bit..
sometimes dual channel also give some prob...
is it becoz of nf570?

but i think 667 ddr reaching 1000 on 250fsb quite high..

i've tried 800 divider works fine on 200fsb.. but need more vdimm, maybe on 250fsb require more.. which i cannot try coz my board limit it..

thinking to grab nf590 instead..

@8tvt, prolly you did not understand what i mean

the board does not let me use DDR2-800 at all ... if i put DDR2-800, it will revert back to DDR2-667 but the timings remain the same.... as if DDR2-800 divider never existed.

it's not about ram not stable or whatsoever.... hey... i've been using AM2 long enuff

yup.. that's right.. its not the ram problem but the mobo itself do not let me use the 800 Divider
My Kingston is DDR2 with Hynix chippy but dunno wat type..(lazy to open my case to take a look as my NT06 fully blocked my DDR slot )
that why i want to try how far my ram can go.. right now max till DDR940..

that's why i really think.. got something missing on nf570..
i just can't elaborate more.. coz mem controller on the cpu itself..
either bios or the mobo...

i read somewhere.. other brand that using nf570 give problem with 800 divider..
maybe here http://www.hexus.net/content/item.php?item=6150&page=5

Much better than m2ne. No more cold boot problem and a couple of issues regarding starting up my system when im O/C. More than 1.95v dram. And umm donno la maybe because i paid more so i feel its better

aiseh..late reply la abg duarnt..
edi bought it tadi...
rm 420 viewnet..will test tonight..
hoping don't have any problem lahh..

Has anyone had any problems with the 2.2vDimm jumper on this board? For some reason it only locks it at 2.0v, not 2.2v like its supposed to. Really sad la, since most DDR2 can easilt survive up to 2.2-2.3v.

Btw, what should I google for when searching for the modded BIOS? So far I've only seen modded bios for the 754 and 939 versions, not AM2.

lohwenli... check out this link, might be helpful

Same shop la even the same price. Other shop dont have DFI or dont have the nf570. With u using ddr800 i confident u wont regret it.

ddr533 without manual timing isn't gonna work...

Some interesting updates with my processor in the past few days. Here's the log (sorry no screenie)

Wednesday
1. 280x10 @ 1.475V - SP2004 failed after around 10mins.
2. Increased voltage to 1.5V - SP2004 failed after around 1 hour.
3. Ran SiSandra burn in for a few hours.
4. PC turned off to rest.

Thursday
1. 280x10 @ 1.5V - SP2004 failed after around 4 hours.
2. Ran SiSandra burn in for a few hours.
3. PC turned off to rest.

Friday
1. 280x10 @ 1.5V - SP2004 failed after around 8 hours.
2. Ran SiSandra burn in for a few hours
3. PC turned off to rest.

Saturday (today)
1. Ran SiSandra burn in for about 2 hours.
2. PC turned off to rest, went out.
3. Lowered voltage to 1.475V (280x10)
4. Running SP2004 - still running after 2 hours
