** OFFICIAL ** Intel DX38BT & DX48BT2 BoneTrail Thread

[Randy]

I need a little help here, Ive been trying to overclock with Bios's newer than 1478 and have been unsuccessful

Bios 1478 Settings
Fsb 450
Ref Freq 400
Mem Freq 1333
Mem Timings 7-7-7-20 2T




Bios 1521 & 1554 Will not operate at these settings, I think its the sub timings that are hanging me up but I have not been able to find the right settings.. It looks like with Bios 1478 my sub timings are 60,4,10,5,5 (from everest under chipset), I cannot run these timings with newer bios's and I've even tried 88,5,12,6,6 and still no go..

If anyone can suggest some different settings I would very much appreciate it, fornow I'm just sticking with ver 1478..

Try:

10 X 380
333/1333
MCH up to 1.425
CPU @ 1.35V

That should get you to 3.8 with the memory @ 1526. Leave the memory sub settings auto and run the memory @ 7-7-7-20 at your 1.82V.

Also try 60,4,15,7,7

[Randy]

Also try 60,4,15,7,7

And since GTJ actually knows what he is doing, try his suggestion first.

I was trying my damnedest to hold out for a BT2 deal, bit I bit on this, to hold me over until my Intel hookup can wrangle a Q9450. Credit card companies love me.

Down the road, I may move to a Maximus2, or a BT2, but I'm gonna start playing now.

Now to go pickup some DDR3....

Hey PM me if you are interested in some Patriot 1333.

[rchelicopter]

Also try 60,4,15,7,7

Well I tried those sub timings and at:

Fsb 450
Ref Freq 400
Mem Freq 1333
Mem Timings 7-7-7-20 60,4,15,7,7 2T

It loads all the way up to just logging in and then it just goes blank, I tried changing the timings from 7-7-7-20 to 9-9-9-24 and it actually let me log in but froze up shortly after..

I'm running at 400fsb now and it runs OK, any other sub timing suggestions? I would really like tio get it running at the same clocks as i did successfully in Bios 1478. Also i must mention that I'm running 4 stick of DDR and not just 2..

RC,
Does your memory have an XMP profile? If it does, then under the Performance Memory Profiles option on the memory page you should see Automatic, Manual, Profile1, Profile2, etc.

This might be useful, if you have XMP memory. If you select automatic, press enter, then select manual press enter, it will load the default SPD settings for all the timings and sub timings into the manual setting. If you select Profile 1, press enter, then select manual it will load all the XMP profile timings and sub timings into the manual setting.


You sig says 4GB DDR3-1600, is that 4 x 1GB sticks, or 2 x 2GB sticks?

The Corsair 1600 XMP that I have has loads 88, 5, 10, 6, 6 for it's subtimings when selecting Profile 1.

The OCZ 1600 XMP that I have loads 72, 5, 10, 6, 6 for it's Profile 1.

One thing to keep in mind, for tRFC, the first number in the subtimings list a larger number is faster/more aggressive. All the rest lower is faster/more aggressive.

From the timings you last posted 60, 4, 15, 7, 7 you might try raising tRRD up to 5 or 6.

i doubt this would make the difference, but i run my vFSB at 1.35 instead of 1.325. i doubt that's your problem though.

[rchelicopter]

Thanks for the tips Anubi, yes my memory does have the Intel XMP profile (profile 1 in bios) and I have tried that as well, unfortunately it uses the same timings and sub timings i have tried previously. The info regarding the first sub timing (higher number=faster timing) I was un aware of, this could be very helpful as I was always increasing that number to try and get stable..

P.S. I'm running 4x1G sticks of DDR3-1600

I guess what I'm missing is some sort of "proceedure" to set the sub timings to a workable setting, is it recommendable to change multiple sub timings at once or is it better to change just one at a time?

[Anubi]

RC,
Just read your last few posts again. Are you sure it's memory frequency that's causing your trouble? A good way to verify would be to set the memory frequency to 800 (really slow) and see if you still have problems.

[zbogorgon]

anyone got vcore for this mobo ?

[Anubi]

CPU Core voltage can be set up to 1.9v. Is that what you wanted to know?

[zbogorgon]

nop, vcore, 1.9V in bios, is 1.84V real and that is way to low

Well, I'm not 100% sure the problem is the memory, I just assumed so because I was unable to get to my standard overclock (with Bios 1478) in any bios newer than that. One of the reasons I thought that was the addition of sub timings in the bios.

I'm still just struggling along to get to a stable overclock in any bios newer than 1478, which now that I think about it its not absolutely neccessary, I can just stick with the older Bios unless I'm bored and want to "fiddle".

I'll let you guys know if I'm ever successful.

[Manel]

Has anyone tested the 1554 yet? I see no comments on what changed. I've seen the log, know what's new but wanted to know how it feels, any better than 1521?
I guess tRD/Performance Level still not there, right? Hardware monitor still the same?
I wonder if anyone ever get to use the power button on the board, the little switch that's in the board. I have occasionally but what I really wanted to know was if anyone, those fearless ones, have tried soldering a similar switch to the existing but unused reset switch next to it, and if it works. I believe the board is prepared to have it installed, can't understand why Intel wouldn't bother to put it there, would be helpfull.

Looks like you were right my memory speed passes occt and memtest its just now my proc doesnt want to be stable at anything over 3.4Ghz, I'm working on that now..

[rchelicopter]

Well i figured out the problem, the voltage isnt changing when I set it. I verfied this with everest (my old board displayed correct voltage), also when i set voltage offset it does work but it runs way to hot as the voltage is too high. Is it time to RMA my board?

It looks like GJW had this problem as well, did you ever get it resolved.

[Manel]

Windows update has mentioned that there is a driver update for Vista Audio drivers from IDT. However, the drivers available in Intel website are still the same. I guess they didn't have the time to get them there still.
I was reading an article regarding the new Gigabyte boards to be released with the P45 chipset and it seems they are also jumping on the UEFI (aka The Framework) bandwagon, as an alternative to the good ol' BIOS.
Why is it that Intel, which was the initiator of this long awaited (at least by me) BIOS killer, is the only one not working on it, or, at least, talking about it? They have started it and then spawned it as the Tiano project, but no news or improvements have been known of.
I would like to see it for our BT, I keep saying this with hope that the Intel guys are reading this forum.

[GJW]

Yes I had that problem. I received a new board from Intel and it went all bad. So I bought an Asus Maximus Extreme and moved forward with that. Eventually Intel did offer to exchange the DX38BT I had for a DX48BT2, which I accepted. Last week I put together another machine with that board and a QX9770 CPU. I am still running the 1521 bios version. It has the exact same problem, can't change CPU voltage. I get back home tomorrow and I will load in the new bios and see what I can do. I also could not get the beta version of IDCC to work (running Vista Ultimate 64 bit) but there is also a newer version of that. If that works, I'll try to change the CPU voltage through that as well. I'd rather do it in the bios, but if that's the only way that works.....

I'll report back when I have answers.

So you had this problem on an X38, because my previous X38 was fine it's only this X48 I have that doesn't change voltage. I'm starting to get nervous because I'm recieving a new board today, I hope it doesnt have the same problem..

[GJW]

So far I have had this problem on the one DX38BT that I had functional for a while and now I have it on the DX48BT with all totally different hardware. Different CPU, different RAM, different everything.

I do have another DX48BT that I will build up in the next few months, but I'm going into it thinking that I won't be able to change CPU voltage.

[down8]

My DX38BT should be arriv9ing any minute now.... Sweet!

Time to break out the Rocketfish & HX620, and order some H2O kit.

Now just waiting on Aeneon DDR3 to arrive....

[xMrBunglex]

no one told him about Voltage Offset

[GJW]

Latest bios still no control over voltage. I'm glad my primary machine is an Asus board.....

I found I can control the voltage only if i completely remove power from the computer for a few minutes after making any changes.. This goes for any changes made in the Bios.
