there's no 9.5 multiplier table there.

having problem with low divider on high fsb? iinm, i read somewhere that you need to tweak the trfc if having problem with low divider on high fsb on Biostar mobo. not very sure though...

Guys, I am quite new at OC and AM2 but I have done enough reading. My upcoming rig is sth like

AM2 3600 Brisbane
Asus M2N-E
Kingmax 1gb X 2 800mhz
Asus Nvidia 8600GT

Why most of you didnt increase CPU multiplier to 10? And how come most of you guys not using 800mhz memory since it's cheap?

Kindly advise. Thanks.

most of the time i tweak basic timing.. sub option i'll leave it auto..can save much time..
since tighter timing make more transfer rates.. so it won't interest me much to try higher with loose timing..

brisbane 3600+ cpuMul is 9.5.. we cannot increase it, only can change downward..
800Mhz ram won't cheap.. it's RM100 more than 667 DDR2 for 1gb..
if 2 for dual channel will cost RM200 more..

i know kingmax is cheaper... only recently.. but other brand price not drop yet..

Go for others board because Asus M2N-E got limited vdimm if not mistaken

Should be Year 07 Week 09

max 1.95v to be precise...

see frontpage for OCable mobo refference...

nice..ok thanks...been selling a few of this ade..didnt know how they high they would oc lol...which batch is the best for ocing?

Brisbane up to 3GHz, do I need to change the voltage? At stock volt, how high Brisbane can go, in range? Board, thinking of Biostar TA690G

Biostar has released AM2+ board, but HT up to 2GHz only while Phenom HT 3GHz

Don use Asus M2N-E if can i think vdimm problem still not solve max 1.95v althought it look cool

limited for OC

And DDR2 800 not cheap ler~ better get DDr2 667 and oc it. some of it can do till DDr 1000
if i not mistaken it is crusial~ and got bulks there quite cheap~ use Micron D9 more~

Didn't notice until you mentioned. But anyway, here's the formula to calculate

Ram speed = multiplier * 200 / lowest number that does not overclock ram * 2

The memory controller will only accept the following speeds DDR400, DDR533, DDR667 and DDR800. The lowest divider (meaning highest ram speed) is 5.

Therefore if you set DDR800,
9.5 * 200 / 5 * 2= DDR760 -ram can't be set any higher because no higher divider than 5. Ram is not overclocked, so this will be used

For DDR667
9.5 * 200 / 5 * 2= DDR760 -CPU thinks ram is overclocked, so it will used a lower multiplier
9.5 * 200 / 6 * 2= DDR633 -CPU thinks ram is not overclocked, so this will be used

For DDR533
9.5 * 200 / 7 * 2= DDR543 -CPU thinks ram is overclocked, so it will used a lower multiplier
9.5 * 200 / 8 * 2= DDR475 -CPU thinks ram is not overclocked, so this will be used

The memory controller will choose the divider based the ram speed setting and CPU multiplier with the aim of having a ram speed as close as possible to the ram speed setting while not overclocking the ram while assuming base clock is 200. The base clock does not affect the choice of ram divider, which is why overclocking ram is possible even for DDR800 which does not have a higher speed setting to use.

iinm, trfc is not timing, more to drive strength. Some Tforce 550 user on other forum verified that with loosen the trfc, you can set low divider(400/533) on high HTT. increasing the cpu speed while limiting ram speed(so that u can tighten the timing).

i might be wrong..



that means, my actual divider on DDR533 setting is /8 ?

What I'll really like to know is how high it will overclock (don't we all want to know?). If it can reach at least 3.6GHz it should be enough to keep neck to neck when intel's Penryn comes out. Pretty much guaranteed Penryn will be able to clock 4Ghz or higher. With a probably IPC advantage of at least 20% (about 30-50% advantage vs current C2D) a 3.6GHz Agena might be able to hold up against a 4GHz Penryn.

AMD needs to revamp their transistor tech fast and get their production line running faster. Intel has learnt its lesson after Pentium got burned by Athlon64 for nearly half a decade; and they seem to be taking it quite personally. It would be very sad if AMD got knocked out, then there would be no competition in the market to push prices down and technology developments up.

Added on June 12, 2007, 9:53 pmMost likely, because on /7 it will be faster than 533 while on 200HTT, and the processor won't allow that.

that means cpuz reading is wrong?

Possible..

hey its crucial ok u sounds like cursing my sexy rams haha jk
yeah u should get crucial rams
im using the 800mhz and my 3600+ 90nm junk can go till 2.5ghz with just a capalang gigabyte mobo..
go grab those sexy rams from shawty's threads

hah, looks like brisbane 3600 is being very common nowadays, even newbie manage to found it.

seen all those 3ghz clockers, keeps me drooling..i really feels the need to feel the sensation.. sigh.

ya, go grab one syarat.

worth the upgrade IMO

capriodimitri, why u insist to run at full bus speed? just wonder.

Gigabyte never good in Am2 OC, Intel yes.
For AM2, the brand u should target are biostar/DFI/Abit.

but becareful not to grab the 65w windsor version...
always check for Ordering P/N number is ADO3600xxxDD (tray) and ADO3600DDBOX (PIB) before pay..

save ur hassle just get biostar TA690G.. should around 3++..
if cannot get in ur place just buy it here n courier..

yes u can drop the cpuMul...

M2N-E is a stable mobo... only the limited vdimm make it not a choice for OCer

brisbane 3600+ not only DD but some DL..

i second that..
