** OFFICIAL ** Intel DX38BT & DX48BT2 BoneTrail Thread

[xMrBunglex]

your memory benchmarks are low. my memory is running a lot slower than yours and my Everest benchmarks are a lot higher. timings vs. MHz?

[oldsarge]

Yeah, this is the best I can do with four dimms. I can tighten up the timing if I remove two. I got some improvement above by raising Vmch which is working harder with four modules. Also, maybe you have better memory with the new Micron chips? I have the D9GTR ICs.

[down8]

What other programs should I try, to check the RAM speed? Everest won't work, CPU-Z is unreliable, and IDCC is questionable.

[xMrBunglex]

Down, use SiSandra. the free version of their program has a memory bandwidth and latency benchmark. expect your Sandra scores to be lower than our Everest scores though. i get about 9000 MB/s on the Sandra memory bandwidth test compared to 9800 on Everest.

Sarge, i don't know why kind of chips my Patriots use and forgot the website that listed all of them. if anyone wants to link me, i'll give you a quarter. i don't think my RAM has the best IC's though. i can score over 10,500 when i clock my memory higher, but i found better overall real world performance with slower memory and tighter timings. that's just based on my own testing though.

[oldsarge]

MrBunglex......just to see if the NB was bogging down because of the 4 sticks in my system, I pulled two Dimms and set the memory to your exact readings.
My numbers are still much lower than yours even with a higher cpu speed. I actually was surprised that my Crucial would run at 6-6-6-16! Incidently, all the sub-settings are the same as yours as read on memset.

The one unknown is what memory slots you are using. I am in the blue slots which is correct according to the manual. I have read somewhere that the black slots give better performance, but I wouldn't know why since Intel specifies that the first slot must be populated.....any comments?

This is interesting in that it shows four Dimms apparently do not load the north bridge if you raise the voltage. Maybe I will try the black slots later.

[oldsarge]

MrBunglex........I gave the black slots a go with no improvement. I am giving up. Back to 4 Dimms. At least I found that my Crucial Ballistix would run at the tighter timings, but not as good as yours. Who knows why???

[xMrBunglex]

no clue. i'll put up all my BIOS settings sometime in the next few days so you can compare yours to mine if you want. i do use the black DIMM slots for my memory, but i think it's only necessary if you want to automatically use the XMP profiles.

[down8]

My XMP profile showed while using the blue slots.

Neither showed to work, however. The blue actually was closer to 'working' XMP.

[Nerea]

Hello everyone,

My XMP profile showed while using the blue slots.

Neither showed to work, however. The blue actually was closer to 'working' XMP.

Well I have the same Crucial Ballistix 2 x 1GB as you, and of course neither works here.

I have the DX48BT2 tho, and the processor is the QX9770. I got everything matched for a FSB at 1600 mhz at stock. (My idea was to get a 4 GB kit of memory, but since I saw that the memory is not there yet - is just this gamble with this profiles and stuff I only got this until the "true" JEDEC DDR3 1600 is released).

Ok in my case the computer boots right away as long as I don't load any of the profiles; whenever I load any of the 2, I got in the infamous boot loop (yes watchdog is off), but every time it managed to boot with the profile even if it takes it a while.

I tried with more than one bios with the same exact result.

I ran memtest without any errors with the first profile I imagine would do too with the other, the modules seem to be error free.

I contacted Crucial and was a waste of time, the person said that they didn't release yet XMP parts, (.....?!) and to just load the basic timings and voltage and set the advanced timings in auto... well too bad there isn't auto for the advanced timings, neither I think would do any difference.

How many of you are affected by the boot loop problem, and what modules are you using? This Crucial works right away here if NOT profile is loaded, otherwise might boot at first try but most likely will not if is a cold boot.

I halted to move the system there until I find a way to solve this, since I don't like the stress this issue puts over the system.

Please any settings to make this work at stock settings for me (That is 1600 mhz FSB at 1:1 ratio) and alternatively if there is any memory that really works?

Thank you for your help.

[down8]

So, you got it to boot @ 1600 w/o touching anything?

I had IDCC show me 1600 once, though CPU-Z showed 1333.

Yes, memtest confirmed it. It is running at 1600 mhz.

But it takes a while for it to boot. That is what I am trying to solve.

It boots with any of the profiles from 1.9 (as it read in the profile) to much lower 1.74 ... tried all that to see if I could solve it. I left it at 1.78 V.

[down8]

Which version of memtest shows you the RAM speed?

I still can't get it to boot @ 1600/1.9V anymore. I may move it back to the blue slots and see if that helps.

I used the blue ones and I am using now the black.. but didn't notice any difference.

in your case I would try 1.78V, 1.9 is too high for these modules.

I am using the latest memtest, bios also shows 1600 mhz memory and FSB.

[Nerea]

down8, by chance I found something that might be relevant, see this memory from OCZ:

http://www.ocztechnology.com/product...0_gold_edition

Notice the note they put there regarding the speed:

1600MHz DDR3*


* Test specifications are based on dual core CPUs only. If quad core CPUs are used, higher bus thresholds and core arbitration may necessitate lowering the memory frequency below tested specs.

This could explain something I noticed while trying settings here the past days, when I tried 333/1333 the computer didn't take as much to boot (from none to max of 4) with the default 400/1600 can be much worse.

Since I want to keep 1:1 ratio I am still trying to see what if any settings for 400/1600..... but if you notice most people running the higher memory frequencies here are using dual cores.

I hope that when they release the official memory (JEDEC) PC3-12800 they will accommodate the quad cores... otherwise we would be in the same joke.

[Sean-E-Boy]

well, been a while since i had the time to visit...looks as though things with the newbies are falling apart and gradually being put back together again as usual (dont want anyone to feel like they got cheated because they didnt get to "experience" this board!).

anyway, updated BIOS, and still cannot lock multi.

sean

and GUEST, i think that we are the only 2 with q6700's in here, so when i get some time i will look at what your settings are and see if i can help. right now i am at 362mhz, or somewhere around there, and will probably stay there for now...i have a testy core and really have to crank up the juice to keep it stable.

[down8]

I have a Q6700.

Nerea, are you using:
http://www.memtest.org/
http://www.memtest86.com/
http://hcidesign.com/memtest/ ?

That is interesting about the speed being reduced while running a Quad. I have an E2180 I may be able to test with later, but I don't want ot tear down both machines right now (again).

Hello (I think I solved the problem here)

I am using http://www.memtest.org/

Well today I tried to set just in case 400/800...... the computer enters an endless boot loop with that, I needed to use the jumper. There I set the 333/1333 which used to more or less work (would boot after a very few tries)

Not anymore, it took it way too long and by then I was thinking in getting any other memory since this one was not compatible with this X48. But once I managed to enter the BIOS I tried leaving the reference frequency in auto, still keeping the memory frequency at 1333. It worked at the first try..... but the computer was left with memory at 1333, tried just in case with memory frequency at 1600 (remember leaving the reference frequency for it in auto)

To my amazement it works, works at first boot, cold boot, after turning off PSU etc. I tried booting several times and every time it booted right away.

So no idea if that might work there, but try leaving the memory reference frequency in auto instead of 400 or 333.... while setting the memory frequency where you want it. See if that works.

[down8]

Default/1600 locks - jumper city.

400/1600 => 1333.

Weak.

[Nerea]

(Sorry about the lock :S)

400/1600 => 1333

For 400/1600 and getting 1600.... you need to have the FSB oc to 1600 mhz too. But I have no clue about FSB oc nor CPU, when I build a computer I keep it for a long time..... from 4 to 5 years. So I go for something bleeding edge when the time comes, but I try not to force stuff because I want it to last while being very reliable (my current computer works perfectly after all that time, only upgrading the graphics card) and so did the one before this one.

I always get Intel mobos because of the reliability, and for me was very strange to deal with this memory problems. During these days I tried to see the very basic of what is what in the memory settings, but since I don't oc the system I am the last person to advice on that.

But check this out if you still didn't, is the memory guide for the BT posted by gtj. There you see what numbers you need to get a target memory frequency working.

http://www.peakin.com/x38/calculator.html

I know tho, that computers default to the processor FSB and that is the barrier you need to see at to what point can be overcome. With your processor defaulting to 1066, the mobo at 1300 might be difficult to get the system stable at 1600 mhz, Intel mobos aren't too good for oc.. yet might be possible, the other folks here know how to oc.

Here are my Everest results for my X48

[Pontius]

Hi everyone, I just got this board, and i just found this forum. I'm not really intrested in OCing it that much, I guess I might be having the same problem with the FSB speed and the memory, i set it to 1333 and 9-9-9-24, 1.7v. and it works now, however when I did that, and pretty much anytime I change any settings with the memory, (havent messed with the cpu until i get a better HS and Power supply), I cant get anything to display, and it takes what seems to be a random combination of changing the jumper, and for some reason unplugging and plugging back in my video card. It just seems to be a very finicky board as far as settings go, but I know its a solid board and it had everything I wanted in a board.

Heres my build
I flashed the bios to 1610 or whatever the newest one is.
CORSAIR 2GB (2 x 1GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10600
Core 2 Quad Q9300
Geforce 6800 GS (Im replacing that soon!)

Basically if anyone has a similar build, I wanna know whats a fast, stable setting for my memory, and what the best way to check that it is indeed running at 1333, I dont really want to make it unstable cause Ill probably be running it most of the time.

[Nerea]

Pontius, I wasn't oc either and as you only hoped to get the memory working at rated speed with the rest of the system without problems. Nothing worked for me until yesterday, by chance solved I it by setting the reference frequency in auto, while setting the memory frequency at the rated speed. In your case try auto in the reference frequency instead of 333, and set 1333 in the memory frequency. Also check the voltage.

Besides this, if your system boots without display can be a problem with the graphics card or PSU as you are guessing.

At present I have E6320 1.84 GHz CPU 1066 overlocked with DX38BT:

1. Host Clock Freq 498 MHz
2. Multiplier 6x
3. Memory 400 MHz

The BIOS and Intel Desktop software reports the CPU running at 2.99 GHz.

Windows reports 2.32 GHz

BIOS also reports a different voltage which is setup correct.

Intel Desktop reports:

RED CPU Volt .80
RED MCH Volt .80
RED Power Supply -

Help, the system seems stable, but something is wrong!

If ti's RED, it's not working. Try restart IDCC. Mine goes back and forth from green (working, with correct #s), to not working (red).

[Pontius]

yeah now that you mention it, its more than likely my power supply. everytime ive seen a computer not display something 9 times out of ten its the power supply :P oh well the new one comes in on monday. I'm pretty shure my memory is running at the right speeds now, I know I'm using less memory in windows now so it must be :P thanks

great thread btw I'm super impressed and a little intimidated ha!
