And i also noticed that hibernating has the same affect as soft booting , black screen. Apparently i have to hard boot every time, or shut the power supply off every time if i soft boot. I guess i dont mind hard booting every time, but it's not particularly great for the computer from what i know. If i close all windows prior to hard booting is it still harmful? Either way not a good long term solution

Ok, so i kept everything unchanged but put the ref freq back down to 333 from 400, resulting in an effective memory clock of 1333. Same results as other clocks, system hanged at a black screen, this time i was able to get lucky and reboot 5 or 6 times until i got back to the bios, didn't have to jump it.

So the settings i posted previously are what i am using for now, but my memory is clocked under its rated 1333 memory, and a bit over its SPD of 1066, at an effective memory of 1150ish. This is now on windows xp 64, i was on 32 bit earlier and upgraded.

Hmmm. There's no way that the board should have problems with 333/1333 at 333FSB but if 400 gets you stable, so be it. You could also try 400/1600 as that'll give you the same ratio as 333/1333.

Never tried hibernate so I can't comment there, but your correct in that the hard power cycle isn't a great long term solution.

Also, update your signature so we can see what you're running.

EDIT: Other things to try...
Raise the vFSB slightly and see if that helps
Lower the GTL CPU0 and CPU1 reference voltage percentages by 1 notch or 2.

I'll give it a shot again -- these boards are not particularly user friendly. I don't think I'll mess with intel again on the next go around. I also wish the board was SLI ready so i could be a bit more future proof, maybe in retrospect i should of got that 4870 x2, just didn't care for ATI and i thought nvidia would pull their heads outta their asses and enable SLI eventually on this board.

I used to have the problems you mentioned and then my older PSU went "poof".

When I purchased a new PSU with better specifications than my previous one, both S3 Standby and Hibernate worked much better. It's possible that the +5vbs line may be not providing sufficient current to the board.

What made the S3 Standby totally solid with no further problems of any kind was to also make sure UEFI boot was not enabled (you'll see it in the boot menu of the BIOS).

Hi guys, Nice to join the group.

I couldn't log in for a month and finally was able to.

I read alot of this thread. I have Patriot Extreme 1600, but it doesn't seem to be the favourite mem here.

I wanted to go for ReaperX 1333 6-5-5-18.

Just wanted to know is it worth it??

Besides I can't even get my mem to run at 1333 without being unstable.

[xMrBunglex]

i had 2 gigs of Patriot Viper Extreme 1600 and it was good memory. i ran it at 1600 7-7-7-18 1T and 1500 6-6-6-16 1T. it would probably be a waste to buy memory with slightly better timings.

make sure UEFI boot was not enabled (you'll see it in the boot menu of the BIOS).

i enabled UEFI and it just turned my USB ports off until Windows started to load. the only way to get back into BIOS was to reset the frigging jumper.

Thanks for the reply xMrBunglex.

I imagine that you had to raise cpu timings to run that mem at those settings because it shows 1066 @ stock settings. I can run @ profile1 but had to raise cpu settings and got a stable 1600 XMP.

I don't want the Reaper for faster timmings but rather because I only have 2048 and got a few low mem issues, so I want to go up to 2X2Gig

Is it worth it or just stick to OCZ Gold?

Thanks

[xMrBunglex]

if you want 4 gigs of memory, 2x2 gig is definitely the way to go. i tried 4x1 and it really limited my overclock. i ended buying this G.Skill kit and it rocks. good overclocker, tight timings, cheap price tag. i'd recommend it.

[Zardoc]

Thanks for the input.

i enabled UEFI and it just turned my USB ports off until Windows started to load. the only way to get back into BIOS was to reset the frigging jumper.

I found however, while in standby mode that the USB ports were turned off again. As both keyboard and mouse were USB it forced me to use the power button. That's why I refer to the UEFI when one encounters S3 Standby issues. It wasn't 100% consistant, but majority of the time you'd pound away on the keyboard or run the mouse all over the place with no awaking response.

[Manel]

Don't enable UEFI on this board, unfortunatelly this board will not, almost for sure, have a version for it.
UEFI is supported in Vista SP1 already, but not before anyway.
UEFI will eventually replace the good old BIOS, some manufaturers have already started to sample some boards with it, like MSI, but still not mainstream.
Intel, the project initiator, has it in workstation and server boards, but not in desktop boards. I asked them if there would be UEFI for BoneTrail but the answer was evasive as usual.
Another review is up for the DX48BT2, check it out in: http://www.hothardware.com/Articles/...US-ECS--Intel/
As usual, when it come to oc'ing everyone gets an headache. It takes time and patience, this baby needs a lot of attention first...

I love reviews like this one. 13 pages of absolutely no useful information.

Guys, i´m having problems whit the OC of this mobo... i can only reach 3Ghz 380mhzx8 whit my Q9450, in everest the Vcore seems to be alive.... it change i already disable C1, wachdog so i don´t really understand whats going on because in CPU-z the vcore always is 1.213 no matter what.....also i want to learn the meaning of all setings on bios, does any one knows good documentation other than intel´s one?

my setup:

BX38BT bios 1814
Q9450
2x1Gb Gskill PC12800 7-7-7-18
4870


sorry my bad english

[Manel]

gtj, I posted the link but like you said, it's just another crappy review, like so many nowadays. Grab a couple of mobos and just through a few benches at them and there you have it, a nice review.
Just posted it for you guys to check out if you want.

[Avantlord]

after few atempts to get this mobo with better oc i made a few changes, CPUv= 1.450 FSBv= 1.275 MCH/ICHv= 1.350 multi=8 CLock=415Mhz with this i´m able to boot even to run win but not pass the stability test on everest can anyone help me?

your vCPU may or may not be a little high. it's a lot higher than i run my dual core at though. your vFSB and vMCH seem low to me. with 1.35 vFSB and 1.425 vMCH, i'm able to go as high as 450 FSB without running hot. i'd suggest upping your MCH and FSB volts a bit. you might find you can lower your vCore after you've confirmed stability.

Thanks xMrBunglex great results with your help, my new sets:

vCPU= 1.375v
vFSB= 1.350v
vMCH= 1.425v
FSB= 430Mhz
multi= 8
memory= 1718Mhz
Ref= 400Mhz
idle= 34ºc
load= 51ºC
Aux(i think this is northB?)= 33ºc

i want to go 450 FSB but i dont really want vCPU to high..... so what do you guys think?

[xMrBunglex]

i think that's a pretty nice overclock for a quad. you could probably go higher if you wanted, but i can't imagine why you'd need to. you can always leave a little headroom in case you get bored on a rainy sunday sometime in the future

What the FSB Voltage stands for?
I got overclocked to FSB=423MHz (CPU:9x,3808MHz) with V_FSB=1.200 (Default), V_MCH=1.350 and V_CPU=1.3500 (Not sure for stability on this cpu voltage, but I'm testing)
What Errors or unstabilities I should encounter, if I'm at low FSB Voltage?

[DualCpuUser]

FYI,

I found I can lower my vCPU than using Intel's "Auto" setting, which is nice how it predicts upping the vCore for you. But I found it a bit to aggressive than needed for my qx9770 version. I can run 24x7 at 1.33 (bios) and Enh. power curve along with F@H... I still run 400x9 for 3.6Ghz.

What I hate is their "auto" on GTL ref's are useless.

Unfortunately it'll be general in nature. It might look like a CPU problem or a memory problem. If your system is otherwise stable, I'd leave it. If you wanted to increase it a notch or 2, it won't hurt anything.

[Avantlord]

some people told me that 1.375 vCPU is actually the max vtt for a Q9450..... so i get lower my vCPU and it is stable now at 1.3 on bios, everst CPUID shows me 1.242 and 1.253 variance value for ide and a 1.230 for load
i´m a litte bit scared with the idea of electomigration..... how do i know if i have it on my 45nm quad?

How do you now? It might start out with having to lower running freq. and possibly more volts, which compounds the problem.

OR, the chip just fails.

[Avantlord]

a guy on this thread told me XD

in my case it was a matter of vFSB and vMCH so they fix my stability

[Avantlord]

gtj can you post your vcore, vtt, vmch, gtl´s of your BX38BT with the Q9300 please?
