** OFFICIAL ** Intel DX38BT & DX48BT2 BoneTrail Thread

[djs357]

Sean-E-Boy,
I find this always works. After you shut it down, turn off the power (ie. pull the plug) then push the start button. This will drain the caps in the PSU and allow you to perform a truly cold boot when you turn back on power.

[enigma96]

New here 2nd post :-) I've got the X48 Intel board, and its been rock solid up till now. I installed the latest bios and the latest Intel Matrix driver, not the one for windows, but the one for the floppy drive when you first install a fresh copy of Xp. I run my HD using ahci and its always been fine until this latest version. It will install Xp fine and running 2d stuff its fine also, but when gaming after about 30 minutes or so my system reboots and when I check the event viewer I get a IASTOR.SYS error timed out. I never got that with previous versions. Anyone else with this problem???

Hey, I wounder how you can clock your CPU over 380FSB ?
I read in test with Dx48bt2 and they said it takes stop at 380fsb and it is exakly what happens when i clock my computer, i had Dx48bt2, E8500 @ 3.6 (379), corsair 1333Mhz 2gb.

When I chose something over 380FSB I cant start my computer, the bios said a "post" in bios i wrong and I most take my previous settings again.

I been really happy if someone can help me so I can clock my computer over 380FSB, I want to drive the CPU in 4GHz 24/7 ! =)

[Ramerix]

Hey bro

Hey, i wounder how you and the other guys can overclock your CPU over 380FSB ?!

When I change my FSB to something over 380FSB it doesent work, something in bios is wrong so I need to choose "N" and load with the prevoius setting !
I have read in some "tests with Dx48bt2" that is Difficult to clock more than 380FSB also !

I have the latest bios 1893!? Is it bad ?

I be REALLY happy if somebody can help me to overklock more than 380FSB !

Ramerix,
I got this mobo working even with 500fsb (posted successfully, with increasing the NB voltage)
My opinion is that these mobos (DX38 and DX48) are sensitive to some frequencies!
Try to disable "Watch Dog" in BIOS, because it shows the unsuccessful messages and prevents you from gaining more FSB speeds.
At least doing this, worked for me, hope to work for you too
And if you don't know, first change the Mem/FSB ratio to 800/400 and decrease your CPU multiplier to lowest value, before trying to find the highest working FSB settings

Good Luck

Thanks alot, i tried and it WORKED !=DDD
I run the FSB at 423 and 9 multiplier = 3.8Ghz now.
But Windows could not boot when I have the Reference Frequency at Defualt, 1516Mhz at the memories. So I change the Reference Frequency to 400. And it worked!!
I hope I can rise my FSB to nearly 445 !

Do you think I need to change my Core VID at 9 x 445FSB = 4Ghz ?
I have 1.250 V and the lowest I can choose AFTER 1.250 is 1.28xx ??

And I drive my Mem in orginal FSB now, should I clock them later when I am satisfied with my clock ? :P It will rise the performence to clock the memory ? Aight?!
But I dont know how I clock them without the "automatic" clock when I rise the CPU FSB!

I`m really happy that you help me!!!!

[enigma96]

What slots should I use for memory? I have 2 sticks at 2gb each ddr3 1333. Should I use the black or blue slots?

[Sean-E-Boy]

Enigma,

Not sure how it matters, but Corsair (when talking about using Memory XMP's) says to use the black sockets...sorry I dont have a better answer for you.


Questions for the rest:

With a DX38BT, do we know if there is a FSB limit? I know that in the BIOS it can be adjusted way above 500, but what kind of limitations are there with the internal workings of the MCH or some other component considering that the board's maximum supported non-OC FSB is 333?

What about with memory? Would the x48 be better able to handle keeping the resulting memory frequency in synch with the quad pumped FSB than the x38, or is the frequency/latency of the memory:MCH:processor still going to have the same issues with the x48 at the same FSB?

For instance, when running a Q9550, which has a native FSB of 333, at ~450 (1800 Mhz) on the x38 i cannot keep the system stable if the resulting memory frequency is 1800 Mhz, regardless of the strap used, and memory capability is not the issue. Would the x48 with the same processor, same memory, at 450 FSB, and with the memory running at 1800 Mhz (resulting frequency) have the same instability?

You're Welcome Ramerix
and sorry for delay
I have 2x1GB 1333 Mem,
and once I had my DX38BT, I was unsuccessful in overclocking the memory above 1550MHz, even when I increased my ddr voltage over 2.3V
(I should be honest and say that I didn't test increasing Timings in this level to gain more mem speed)
So I kept the Mem Ref/Freq ratio so that the resulting frequency was below 1550.

Do you think I need to change my Core VID at 9 x 445FSB = 4Ghz ?
I have 1.250 V and the lowest I can choose AFTER 1.250 is 1.28xx ??

As my overclocking notes shows, I had my Vcore at default settings (System Monitoring Showed 1.183V) below FSB Value=420MHz (@9x),
and after that I had to increase the Vcore (1.300V for FSB=423MHz and Vnb=1.350V)

And I drive my Mem in orginal FSB now, should I clock them later when I am satisfied with my clock ? :P It will rise the performence to clock the memory ? Aight?!
But I dont know how I clock them without the "automatic" clock when I rise the CPU FSB!

Yes, I suggest to keep the Mem Ref/Freq @ 400/800 (1/1), to obtain your system maximum working FSB value,
then you can lower this ratio for gaining more System Memory Override Freq.
Look @ the below link, then you can calculate all you need.

Is it me or does the Intel X48 board not like Corsair Xms memory? I have 2 sticks of 2gb each and they seem to run very unstable at default settings. Do I need to change anything like vdimm or the northbridge voltage and what timmings are good??

[redphil]

Is it me or does the Intel X48 board not like Corsair Xms memory?

The board set the voltage for my corsairmemory too low, I had to increase it.

[enigma96]

What should I set the voltage too? And are most of the problems people are having with this board memory related to corsair? And what are these power cycles issues everyone is talking about?

[redphil]

Look on your memory, maybe they printed the advised voltage on it, or you should be able to find it on the corsair-homepage.

[Sean-E-Boy]

Hey gtj,

Regarding my above post-1733, and since you have both the x38 and x48, have you tested or noticed any difference in the ability (or stability) to push the FSB higher on the x48 vs the x38 with the same processor (non-400 FSB) and memory and keeping the memory bus frequency the same as the FSB?

I do a lot of video editing (encoding, re-encoding, transcoding, etc.) and would like to be able to have the memory at 400/1600 or 333/1333 for the increased bandwidth and yet get the processor closer to its limits.

Since the x48 is designed to handle 400 FSB processors and 1600mhz memory, is there more headroom in the MCH for keeping the memory at 1:2 than with the x38?

any insight would be helpful

Thanks.
You wrote that you have Vnb=1.350V, Voltage North Bridge ? If, Witch one should I change in my bios "Front Side Bus Voltage Override or
MCH/ICH Voltage Override"!?

Thanks for all your help !

[Mahyar.FF]

Thanks.

MCH/ICH Voltage Override"!?

Certainly, MCH/ICH Voltage Override=Vnb
But be carefull! I didn't change the "Front Side Bus Voltage Override" in all of the tests, and nothing disturbed me all along.
I don't know if this was my mobo problem or not (will never know either), but you should test this voltage on your own.

[Wesker]

I've been eyeing this board since it was launched, but I already had a Gigabyte X38-DQ6 when the board came out. However, a friend of mine has offered me the X48BT2 for cheap so I've been thinking about setting up a spare gaming/OCing rig with the board (if I get a good hang of things with the X48BT2, then I'll just replace my X38-DQ6 with it).

I've got a question regarding this board's memory compatability though; would the newer low voltage (<= 1.65v) DDR3 sticks work with this board? In theory I know it should, as the new DDR3 RAM follows the exact same JEDEC specs as their higher voltage counterparts (apart from the voltage, obviously).

It would be nice if I could get 2 x 2GB 1.65v DDR3 now for the X48BT2, then another stick later should I decide to upgrade to Nehalem.

Thanks in advance.

I'm starting to get a bit tired of those guys at Intel.
Not only haven't we seen any BIOS update for over 2 months now, at least to correct the power issue and provide some more mem tweaking, they haven't updated IDCC for even longer. It's beta from the beginning and I guess it'll stay that way. The stupidiest thing is that the latest 168 version will not work with BIOS 1893 and a version that will is promised in the website. So far...
But I'm really pi**ed (sorry for the lango here) is that it seems it's not lack of time since for the SmackOver there was a final v4.3 from the start almost and now a new beta v4.4.0.609 with auto-tuning even, imagine that for us too!
Come on you Intel guys, I know you're reading this, give us something for xmas.

[mryerse]

No kidding. Just because X58 is out doesn't mean they should ditch us X38/X48'ers. I'm glad I got a good deal on this board, but it really has been a pain to work with. I finally have it stable. But every time I need to reboot I am so tired of having to reboot 3-4 times just to get it to post. Once in Windows it runs stable as ever for days. But reboot for a security update and you're in for some fun. I can honestly say I will not be buying another Intel board in the near future. Intel chipset, yeah, but not Intel board.

[daleorama78]

I noticed a few threads back you guys were talking about the CPU voltage issue where it wouldnt adjust at all. well I also had this same problem but I figured it out and it may help you guys if you dont already know. My problem was that i was using the absolute newest INF update utility,after I used the older one listed with the board in the DX48BT2 section on Intel's website CPU-z was able to read the correct voltage and I was able to change it in the bios and it actually changed. So then I tried to use the newest INF update on the site which is the one that says INF update utility-Primarily for Intel 4,3,900 series and it gave me higher 3Dmark score and I was able to still change the voltage. Dont know if this helps or not but I spent quite a few hours tryin to figure it out. I dont know how many screenshots Ive seen where people are havin the same problem,even the guys at Tomshardware was having the same problem when they tested the board and even wrote about it. Maybe alot of you guys that cant get stable clocks are having the same issue,you need to use everest to actually see if the CPU voltage is actually changin.You want to look under the sensors tab under computer and look at the CPU core voltage.

[Manel]

First of all, merry xmas everyone.
New updated for LAN drivers v13.5 on Intel's website. They've been working hard on those LAN drivers I guess.
No new BIOS or IDCC versions though. I though Intel would give us a xmas present, but no cigar yet.
Maybe with the new year coming up...

Hi,
I posted a couple months ago with my problmes:
http://67.90.82.13/forums/showpost.p...postcount=1640

I got too busy at work, and hadn't done anything since. Now with the Christmas break, I am back on the job. Two months had gone by, and Windows XP Media Edition didn't want to let me log on, because I had not registered the OS installation.

So I reinstalled the OS, this time on the second hard drive, and that allowed me to log on. Nicely, this also remedied the problem of not being able to "see" both hard drives when in the XP file explorer.

But during the installation, as happened before, I was prompted, "Please insert the Compact Disc labeled 'Windows XP Professional Service Pack 2 CD' into your CD-Rom drive D: and then click OK." I don't have that and it didn't come with the version of XP Media Edition I bought from Tiger Direct. I hit "Cancel" and the installation continued. I didn't think this would be a severe problem but maybe I am wrong. I guess I should follow up with Tiger Direct or MS on this.

After the OS installation was done, I 'woke up' and used the Intel installation disk, and installed the Ethernet drivers the Bonetrail motherboard needs.

So now, I have two problems solved, the 2 hard disks, and the Ethernet drivers.

The problem now is that the Internet Explorer is not installed, and the IE choice in the program browswer is not associated with any application. I can't access the Internet. And perhaps because of this, or maybe not, when I try to register my installation of the OS, it says I can not. So, I have 30 days to get this figured out or the OS is going to shut me off again.

Someone earlier suggested I get the latest BIOS for the mobo. I brought BTX3810J.86A.1893.EB.EXE to the desktop with a thumb drive, and double clicked, to try to do the mobo BIOS update. So it told me in response, "Intel(R) Express BIOS Update Setup failed to launch installation engine: The RPC server is unavailable".

Any thoughts on this? Am I in need of professional help?

I'm trying to set this up for a deaf 11 year old boy with a cochlear implant. I want to add a Video Camera to the system, so that he can try to use it as a speech therapy workstation. So if anyone has any SW ideas for that application, I am 'all ears'.

thanks,
Shemp

[petr0id]

Shemp! Looks like you have bad Micro$oft Windows Install. And try to update your BIOS with bootable CD (.iso available at Intel's web site).

Manel! Not so fast! There is no new LAN drivers:
The file that you are trying to download has either been moved, renamed or archived.
They still work on it.

[Sean-E-Boy]

Shemp,

One thing you could try re the IE issue is to download IE7 on another computer and then move it via usb drive to the problem computer and see if it will install. link to dl: http://www.microsoft.com/downloads/d...displaylang=en

Now I have not used media center edition of xp before, so not sure how it differs from plain old xp, but I would investigate the following: control panel> add/remove programs> left hand side click on the option to the effect of turn on/off windows components. it may take a while to populate, but at one point in time you could disable IE from here...so maybe you can enable it from here too.

However, I think that the RPC error is the crux of probably 99% of your problems...without it "start button based" microsoft OSs make your computer kinda like a viper without an engine...an expensive chunk of nearly worthless metal. ANYWAY, if you can, right click my computer in the start menu and choose manage. on the left there should be an option like services and applications, click that. now in the main frame of the window, double click services and you should get a list of things. browse down to "remote procedure call" and take a look at its status. if it is started DO NOT stop or disable it. if in the status column it says stopped or is blank, double click it and in the pop up window make sure that automatic is selected for startup type (although this will probably be grayed out and you wont be able to do anything) and click the button that says start.

If it starts, try browsing the computer to C:\Program Files\Internet Explorer and see if it exists and if so if you can open IE by clicking on iexplore.exe or try updating the BIOS and see what happens. If you were unable to start the RPC service, or it wasnt there at all, this is probably why windows wants you to insert the SP2 disc...so it can reinstall the files needed to get this working properly. Now you should be able to use any xp disc here so windows can get the files it needs, even if it isnt media center edition.

I am sure I can come up with a few more ideas to try if none of this works, so just let me know whats going on. feel free to PM me too so we dont upset the forum gods.

Hi petr0id, yes I know. Been trying to dl it but so far no go. I guess some last minute update/correction was in order.
