** OFFICIAL ** Intel DX38BT & DX48BT2 BoneTrail Thread

[Randy]

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.

[Randy]

Well,
after trying a bunch of combinations of settings, I just don't think my memory is going to get me where I want to be (wherever that is!). If I get the CPU close to 3.8, Orthos halts with memory errors.

You know, the farthest memory slot is packed so tight in my case. I may try mounting a fan over them temporarily to see if that helps.

This memory is funny. If I bump it over or under 1.82 it's totally unstable. Of course, with this board I never really know where voltages are anyway.

[gtj]

At 380 FSB, your pc3-10666 memory is running at pc3-12160. If it's rated at 7-7-7-20 at 10666, you're right on the edge. You may have to loosen the timings slightly to compensate for the extra 2 sticks.

[gtj]

OK, I got my BT2 up and running.

First, the bad news...
Don't expect it to fix any of the quirks if the BT. It's the same board with a "DX48BT2" sticker over the "DX38BT" painted on the board. Same BIOS as well, of course.

Now the good news...
Combined with the E8500, this thing is running at 460x9.5 with less vMCH. Of course the E8500 needs less vCORE as well but that's not related to the board. I haven't started tuning the memory yet.

[down8]

Definitely keep us updated!

I was looking forward to a BT2, but I'm thinking on waiting until Nehalem now.

[RRGHOST2006]

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.

[Sean-E-Boy]

RRGHOST2006,

In OCing to 1333 as you have done, have you tried running it with both sticks individually? The series of 3 beeps, in my experience, generally refers to faulty ram or not a powerful enough PSU, but you seem to have that one covered.

one trick with my setup that i have noticed, and posted recently, is that i cannot overclock stepwise (gradually increasing my FSB) to where i am currently (375x10) with my memory running at 333/1333.

i have to run the memory at 333/800, with the FSB at say 360, then boot, then shutdown, then up the memory to 333/1033, then boot and shutdown, then up the memory again to 333/1333 boot and shutdown followed finally by upping the FSB to 375.

any other method of getting to this combination 10x375, 333/1333 results in failure to POST.

but again, as far as the beeps go, havent had any issues since i first got my system and had to RMA the memory because one stick was bad...individually they both would boot to stock settings, both FSB and MEM, but not together...would get the 3 beeps.

Can you add your system specs to your sig?

what are your vMCH and memory voltages? and what memory ref are you using? ie 400/1333, 333/1333, etc

[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

Hi GHOST and ,

You may have to boot with 1 stick, then increase some voltages a little before you get stable with 2x2gb sticks. Let us know what the rest of your gear is and we'll help you out.

I changed the title of this thread to include the DX48BT2 since it's the same board and BIOS.

I've started tuning the memory and it's looking pretty good. I'm now at 450x9.5 1333/333 7-7-7-21 1T with 1.425 vMCH (prime95 12hr stable). I was not able to get close to that with the X38.

[xMrBunglex]

Ghost, check your memory settings. if you have it set to Auto by SPD, it might not work. better to manually set your timings anyway. also, i had to overvolt my RAM by .1V to get it to run at advertised settings. i'm not sure if that was the fault of the Bone Trail or my RAM.

[RRGHOST2006]

These are my SPECS

Thanks for the welcome George
I've been looking all over the net to get this matter resolved and
still no luck so im hoping you guys can point me in the right direction
But first i have to ask is the DX38BT2 available to buy yet?
Second is how can i with these system specs get the 4 Gb i bought
to run properly with this mobo

2 sticks of ram

Thanks for all the help everybody
i will try whatever you suggest to solve this dilema

The DX48BT2 is available now but you won't see any benefit with a Q6600 and the DDR3-1333 memory.

So, here's where I'd start...
On the Processor page
vCORE: 1.3250
FSB: 333
leave everything else at default

On the memory page...
266/1066
7-7-7-20
vDIMM: 1.74v
Leave everything else at default

Let us know what happens.

Oops, one extra thing... Move the config jumper to maintenance mode and reboot. On the Maintenance screen, disable the watchdog.

[rchelicopter]

Do you think i would see any benefit with the x48? I've been dying to buy it.. I'm currently running at 450x8 and mem at 1500. No matter what I try I cannot get my memory to run any faster than 1500 at any ratio..

The X48 isn't really going to help get the memory running at better than 1500. The X38 is pushing mine to 1800 (but they're 1800's).

I think you just have to find the right balance between FSB and memory speed. 1600 doesn't really "fit" evenly.

[RRGHOST2006]

ok george using the settings you gave me i booted it with 1 stick and
it booted xtremely fast as though it was going to windows then it would reboot, this occured about 3 times til i said the hell with this..?!

using 2 sticks it booted windows loading screen and then rebooted itself
upon loading again it stuck at a black screen with EB_ at the bottom of the screen?

what next George .......and again i want to thank everyone for their help !

AND also George the term vCORE refers to the
CPU voltage Override .............CORRECT???????????

also i remember reading something about the Command Rate what is that
and what should it be set at ????

as of right now it is at auto...

im sorry for all the questions...

GHOST

also while typing the post above the screen froze in bios on my other pc
while at those settings with 4Gb RAM

You're getting close...
Go to www.memtest.org and download the bootable ISO for version 2.01 and burn it to CD or DVD. Booting to memtest will give you a quick way to test without booting all the way to Windows.

Next put both the sticks in the BLACK slots and increase the vCORE by 2 steps. Now try varying the vDIMM up and down from 1.74 1 step at a time and boot to memtest.

If memtest passes 2 minutes with the default test, run test 7 and see what happens. (Press C 1 3 7 to run the test). If it survives at least 2 passes without errors, boot the machine to Windows and run Prime95 and see how it goes. If it fails at any time, go back to the BIOS and try varying the vDIMM a little. It can only take 1 step to go from stable to unstable.

AND also George the term vCORE refers to the
CPU voltage Override .............CORRECT???????????

Yep. I couldn't remember exactly what it was named.

also i remember reading something about the Command Rate what is that
and what should it be set at ????

GHOST

Auto is OK for now. With 2 sticks it's probably doing 1T which is good.
No worries!

Keep at it! It takes a while to get this board tuned in.

Wow, when you said 1600 doesnt really "fit" I tried 1800 (333/1333) at 450 and it worked better than at 1600. It doesnt quit pass OCCT yet but I feel like I could get it with alittle more trying. Also, I was always wondering are you running 4 mem sticks or only 2, as I'm running all 4..

Also I'm currently havibg the best success with Bios 1478

333/1333 @ 450 FSB is a great place to be. If you can boot Windows at all then you're very close. You may have to loosen your timings or raise your vDIMM a tad to be stable.

I'm running 4 sticks. I had to raise my vMCH a notch or 2 to compensate for the extra sticks but it's been fine otherwise. If you don't have a fan on your MCH it might be a good idea.

i'm stuck at the same place you are. i'm running 450 FSB and can't get my memory to 1800 for that 1:2 ratio. i've upped vMEM and vMCH both to levels i wasn't entirely comfortable with and loosened my memory's timings all the way up to 9-9-9-28. still no love.

unfortunately, i have to run my memory underclocked at DDR1500 until/if i get this straightened out. i'm surprised that my DDR1600 memory can't overclock that little bit more. i may have overlooked something though. i haven't given up yet.

[bobov]

I've started tuning the memory and it's looking pretty good. I'm now at 450x9.5 1333/333 7-7-7-21 1T with 1.425 vMCH (prime95 12hr stable). I was not able to get close to that with the X38.

So you are running at 900MHz 7-7-7-21-1T with 4x1GB memores?

[RRGHOST2006]

OK with 2 sticks of ram at 4 gigs
processor over clocked to 333
vcore 135.0
ram 1066/266
BOTH STICKS IN THE BLACK SLOTS
ram voltage at 1.78

PC wont boot into bios again
just sits at a black screen with a white underscore at the top right corner

when rebooting it a couple times it will also boot to a black screen then
the monitor will shut down completely

ALSO sometimes the monitor wont turn on at all ?

ive just gotten it as far as the intel logo AND it froze

[gtj]

So you are running at 900MHz 7-7-7-21-1T with 4x1GB memores?

Nope running 2x1gb right now. I wanted to see what it would do with only 2 sticks before putting the other 2 in. I'll probably do that tonight.

[gtj]

I think you're just going to have to tweak a little at a time to find a good spot. Try, 8-8-8-24 for the timings, moving vDIMM up or down a notch, moving vCORE up or down a notch, etc.

Leave the reference and memory frequencies at 266/1066 and the FSB at 333. Also, don't change the MCH or FSB voltages. At 333 FSB they're not overclocked.

You can also try setting your multiplier down a notch. If you're system boots fine then the problem area is the processor. If it still doesn't boot correctly, then the problem area is the memory.

Whatever you do, only change 1 thing at a time.

[xMrBunglex]

what's the purpose of putting the RAM in the black slots? does that force a 2T command rate or something?
