Nope. You have to tweak the memory freq, reference freq, fsb and mult.

Adding memory puts more stress on the MCH so that means increasing the vMCH, increasing the strap (reference frequency) or both.

I stopped at 1.35 for the MCH. Do think I pulled the plug too soon? What is the "strap" ?

Also,
I have to volt my memory @ 1.82 for stability. That seems high based on others I have read. Is there any corellation between a higher memory voltage and the need for a higher MCH voltage ?

Sorry for all the questions, but any help is appreciated.

With 1.35 vMCH you've got plenty of room. Try 1.4 and see what happens. You shouldn't need any more than that at 380 FSB. The "strap" is the equivalent of setting the internal timings of the MCH. Just like memory...the lower the numbers give you lower latency but you have to keep the speed low to get it to work. The strap is actually the reference frequency. How do you have the reference and memory frequencies set now?

Generally speaking, if the system is running fine with 2 sticks then increasing the vMCH a bit can usually get you over the hump with 4 sticks. Both the vDIMM and vMCH are related to speed but the vMCH is also related to how many sticks the MCH has to manage.

Added additional 2GB.

MCH @ 1.375
10 X 350 FSB
CPU @ 1.375, but Everest reports 1.32

333 ref/1333freq

Orthos fails almost immediately, but Windows is stable ?

I will go to 1.4 on MCH and see what happens.

I'm really hoping someone can help
me out here I'm trying to oc my
dx38bt mobo

I have read this forum many of times
now and still no luck

My system specs are as followed

Mobo : DX38BT
Ram : Patriot DDR3 Viper Fin (1333) pc310666 2x2gb
Cpu : Q6600
Psu : OCZ gamer extreme 1100 watts

My problem is this I am trying to get all 4 gigs of ram to register in my bios
while oc'ing the CPU to 1333, .... I can and have oc'd my CPU to 1333 by increasing the clock speed (fsb) to 333 but and leaving the ram settings at
default BUT this can only be done using 1 stick of 2gb of ram
I bought 4 gigs of ram with the intention
of using all 4 gigs but as of right now I have
not been able to.
I have tried numerous of times constanly changing
the settings in bios but no luck I'm really hoping
someone can help me out, thanks

Ram : specs are as followed

7-7-7-20 1333mhz DDR3

Upon my many times of trying I encountered errors
consisting of 3 beeps, multiple involuntary reboots, no display, ECT

Now it is running windows xp home sp3 no problem but
with only 1 2gb stick of ram.

[RRGHOST2006]

well thanks for the fast response
Sean
As of right now my specs are all
default ... But as that is only with
1 stick of 2gb ram

1066/default
vmch for the ram is 15.4
whatever default is I don't have
my system at work with me
when I get home I will give you the
exact specs when I do

I have tried multiple combinations
such as 1333/400 , 1333/333
800/333 all while keeping my fsb
to 333 raising the vmch I not sure
what needs to be set in order to
proceed in all this.

Processor multiplier is at x9

As far as the 3 beeps I think there
is a bug in the bios because it did
that for a while with both sticks and using
The same ram it is fine now so I don't know
why but anyway at one time I found that
if I unplugged the 4 additional plugs from
the Psu to the mobo basically turned the
24 pin plug to the mobo to 20 the beeps
Stopped I don't know why but it worked
then after going to bed when I woke up
I had to plug them back in to make
the beeping stop
but when all settings were back to default
using 1 2gb stick everything works fine now...

But i will try your methodvand I
hope it works I really want to get
both sticks of ram in there
I would have 4 gigs then

I have read before that post you
are refering to but I have not yet
been able to accomplish it in full
due to the system not posting
if you can please leave me step
by step instructions on exactly what
to do and I will try that
and reply with the results
3.0 is good enough for me
So I know the fsb has to be 333
but I am lost after that

Thanks again GHOST
