mr ah khoo... did u try lowering HT link and NB both to 1600mhz when trying to oc ur B2?

mine could boot at 2.7ghz at stock volts... not prime stable
voltage might not be the issue since no matter how much I add also won't be stable..

That is very hard to answer u
Take mine as an example.... a B2 9500 ( 2.2ghz default )

210 HTT = ( 2.310ghz ) prime stable stock volts
220 HTT = ( 2.420ghz ) prime stable stock volts
230 HTT = ( 2.530ghz ) prime stable stock volts
240 HTT = ( 2.640ghz ) prime stable only for 1 hour on stock volts ( no matter how much I increase vcore its not stable )
246 HTT = ( 2.706ghz ) stock volts able to boot into windows ( BSOD or freeze after a few minutes using windows )

haha.. mr ah khoo, are we both going to take a dive and grab BE?
i'll freakout if after i buy BE only can oc to 2.7 or 2.8... waste money then LOL

@8tvt
my vdimm now is 2v. might try 2.1v and unganged tonite to see if things get better

That is indeed my plan. But you know la, sometimes feel the rush or impluse to buy.....

I might not even buy SB750, i'll see how reviews look on it first.
Its a hunch, but I think SB750 will not help oc phenom better actually... marketing gimmick.
Change mobo and proc just to get an extra 200mhz??? hmmm....

Hmmm i remember i've read at tgdaily and also at fudzilla that sb750 supposed to bump phenom multi higher abit.. giving us free 200-300mhz?

some news about unlocking the 6 hidden multi pins on a phenom.
I wonder does it apply to B2's...

Something to do with this.

I think will only support 1066 when u using a phenom with this mobo.
Either that or capable OC to 1066.

For fun, benched 1M on 240HTT stock vcore


Able to boot and see my own CPUID at 246HTT, not even Super PI capable yet...


Loosen memory timings in hopes of stable OC? Any sifu here to help?

Its more to NB multiplier... so when I lower the multi I must lower HTT link too. HTT link cannot be
higher than NB if I'm not mistaken?

Can only post until 250HTT which nets me 2750mhz.. somemore post not stable.

Erm, will show rams later tonite or next week. Working on the weekends +_+

Nope. Infact if my mobo can undervolt, I would go to 1.1v or 1.15v...

Any phenom (not 9350e/9150e ar...) he puts on his mobo will fly hehe, come on 8tvt... take the dive and suffer with us

If only phenom is like F3... stock volts oc kao kao....

LOL... i'm still putting hope in my B2.
Target now is stable on 2.64ghz on stock volts...
Then 2.7ghz stock volts...
Then 2.8ghz stock volts...

I'm dreaming LOL

Nope.... should not be that high while idle.
Touch the HSF to double confirm....

Random fun before I sleep.

1.15v vcore at 240HTT
SuperPI 1M bench......

Thanks mr ah khoo... actually got another one.
1.15v vcore / 246HTT / Tighter memory timings = SuperPI 1M


....ok now I really sleep. Phenom too confusing to mess with.
enuff got today. Gudnite

Thanks bro. It seems that lowered vcore makes it abit more stable at 2.7ghz

Not prime stable...

My mobo sets the vcore at 1.25v at default. My bios does not allow undervolting, but
i found a way to set it in the bios anyway LOL

Yeah 1.15v considered undervolt...

Anandtech has a little preview/teaser on the platform already.
Nice looking new AMD overdrive... red color skinned.

Used rebel's haven modded bios ver612. I never had to clear since I've used it.
Not only that, but booting up is faster too

I'm closing in on why phenom clocks up terrible.
At first I thought it has nothing to do with the SB600 mobo of mine.

Seems like it has everything(well nearly...) to do with the southbridge.
When my phenom clocks up to 240HTT, my 9600GT starts to crap out when running stability tests.
Previously fine when i'm at 220~230HTT. When pushing up HTT, PCI clock gets bumped up too??
Well I have no way to adjust the PCI clock or lock it at the bios...

Hitting 250HTT, internet explorer starts to go turbo mode, audio is out of synch.
Its as if when I bump up the HTT, the southbrigde bumps every other clock up, causing everything
to be unstable. If I were to leave my HTT on 200, suddenly my 9600GT can overclock higher than usual.

When(or if) SB750 or a fixed SB comes out, i think we all phenom owner's (B2, B3) should have no problem
running phenom up to 2.8 ~ 3ghz on stock volts by upping the HTT. Else we'll have to go the black edition way..

Anyone knows more? I may be wrong though.

so far no issue with my mobo hehe... feel sad to let go my mobo if really SB750 that good.
rebelshaven moderator used 9850BE on TA770.. he got up to 3.3ghz
another forumer there using 9950BE... hitting 3.5ghz..

so far no reports of RMA yet from them

Welcome to the phenom team....

For starters, go into bios, under the page where you can change CPU settings.. just input 220 instead of the default 200 value.

So your phenom will get bumped up to 2.42ghz instead of 2.2ghz.

You should have no prob with that
