Testing / comparing : Intel D975XBX2 / Asus P5B DX ***56K WARNING***

[nealh]

I've got an odd one. I am using Vista 32 Ultimate, and was using my Logitech Quickcam Vision when my computer blue screened and went to restart itself. When it went to load windows it claimed one of the loader files had a bad header and that I would need to do a repair from the Vista DVD. Ya right!

I power it off again, but then it failed to POST! I have a minor OC of 333fsb, 1.38vcore, 266/800 4-4-4-12 @ 2.32v memory (4x 1gb ocz titanium alpha). I move the jumper to maintenance mode and power back on and it gives me memory error beep codes! I had to pull 3 sticks to make it into the bios! I reset the memory voltage back to 2.32 in the bios and save but it still won't POST in normal mode.

I had to change my memory divider to 266/533 for it to boot in normal mode! Vista loaded just fine (I knew the files couldn't have been corrupt).

What gives? Any suggestion why my memory will no longer run at 266/800 on 333fsb? Is it possible the MB is damaging the modules?

Regards,
Sker

I found on my board I could not get 266:800 or 333:800 to work...not sure why(well 266:800 is way too high mhz on my ram)..but 333:800 should be fine since my ram would have be at like 460(it will run winxp at 487 or 266:667)

not 50 passes of all the tests..ugh

50 passes on test 5...this about 1 hr -1.5 hr max

test 5 ..always seem to be the one that failed for me if I pushed too much and if I dont get 50 passes(like i said once i hit like 38 passes amd then got memory errors), i get issues..ie dvd burns for example..yet Prime 95 passed fine

I personally like Prime 95 version 2.51....but orthos is fine but uses older version of prime, FWIW

when i set 3500..390x9 with ram at 487mhz(266:533) 2.16v 5-5-5-18...I can pass 50 passes on test5 but I could not get 3Dmark05 to run without pushing vcore up...it seems the cpu is getting stressed but I thought the memory controller was on the nB and not on the die of the cpu
with the opterons/A64 dual cores...if you pushed ram speed/timings this was common problem and I would need more vcore
I was surprised this happened on my C2D

I did not push past 1.6v on mch to see if I could get 266:533 stable at 5-5-5-18(also it maybe the 18 should be lowered ...sometimes it is weird how a lower timing may help too)

How do you get 487mhz (266:533) at 390x9? According to the strap calculator it should be 391mhz.

Anyways I think it was my Everest version. Woke up this morning and I passed Orthos 8 hours with load temps right at 60 degrees. Saw gtj's post so I went and downloaded the newest Everest trial and refreshed the benchmarks a few times and no crashes yet. This is at 5-5-5-16 though so I'll have to test more later

sorry should have typed 390 fsb........266:667=487

I have no issues with 266:533 and 390 fsb...3500 9x 390..1:1 ram 391 4-4-4-12 2.0v

Try 266:533. I cant get 266:667 on 390+ FSB.

D9GMH, DDR1200 with P5B-D (Gskill 6400HZ)

EDIT: Now i see, 266:533....Maybe your E6600 cant run at 400FSB.

Been running 266:533 all this while. No boot on 266:667. Orthos error in 333:667 in 15 secs time.

Are you in the club ?

Been running 266:533 all this while. No boot on 266:667. Orthos error in 333:667 in 15 secs time.

My old E66 (L630A) can do 3500 @ 1.49V.....3600Mhz maybe with DI and 1.8Vcore . I never get it stable @ 3.6Ghz

My new E6400 (L626A) can run at 3600Mhz @ 1.42V, 3700Mhz @ 1.48....My BX2 tops around 440FSB on 266 strap, and 465 on 333 strap. Orthos stable.

It's just luck...

So...now what ? End of the line?

your temps seem high
shouldnt need more than 1.6 mch and 1.4-425 fsb for 400

[Lome]

about memtest
I find test 5 and 8 to be the ones i get errors in if something is wrong
for me 5 tends to be NB error and 8 tends to be the ram

ddr2-1000 tracerx

tried 1.6 and 1.4 as well. didn't work. thought u need higher vfsb when yo uare goign for higher fsb

not in my experiance with 3 boards those volts where all that was needed to attain 400

[Skerlnik]

You may have to increase the vMCH with 4 sticks. I had to.

You might also want to update your signature with your specs. It'll help the rest of us help you.

Perhaps I'll give that a try. Strange that it's been working stable for weeks at my vMCH of 1.55v. I'd love to know what happens in the MB when a blue screen occurs. Seems like USB devices play some kind of role.

p.s. I finally managed to get around to updating my signature

My memory can run 500mhz no problem, and the funny thing is that it was running at 266:800 @ 333fsb for weeks. I'm wondering why it suddenly decided to stop

[MuttonFlanks]

Well my comp is 20 hours Orthos stable at 3.42 GHz. Just ordered the Thermaltake Ultra 120 Extreme so I'll wait to get that before I try for 3.6. Pretty happy where I am now, temps on load are at 59-50, idle 41-42 or so.

vcore 1.4500, vfsb 1.350, vmch 1.550, memory was at 5-5-5-18 2.20v. Now it's time to try and tighten the memories. Hopefully they will still do 4-3-3-4 like it did at 3.24GHz.

[Skerlnik]

Ugh. So I updated the BIOS to 2692 using the Express method. I figured I might as well since I had to get in there to change my vMCH setting anyway.

BIOS update worked alright, until it went to load windows... or more like DIDN'T want to load windows.. or anything. It would give me a black screen with a blinking prompt, and that's it. Wouldn't boot from any device (even USB). My RAID & boot device settings were all good, it was driving me nuts. After maybe 15 tries with various settings, I finally disconnected all hard drives and left a bootable CD in the Plextor.

What do you know? It booted. No idea why it was hanging up before. I plug my drives back in, and well... here I am. Back in Windows.

This board is a real headache sometimes! I don't know why it was doing this.

On a happy note, I am running again at 266:800 @ 4-4-4-12. I had to up my vMCH to 1.575.

i think the board laods you custom defaults when you flash bios

[aamsel]

Excuse me, I am a newb to this board (just getting ready to unbox mine) but after reading about the BIOS versions, I am wondering why you would want to use anything past 2333?
Just curious.

Vista compatibility.

[Lyshen]

Since there is a price drop coming, I've decided to get the Badaxe2 and get a quad core.

My question, is there any real difference between getting a Q6600 and the Xeon x3220? I've tried searching around the forum but haven't found much info regarding this. Supposedly the Xeon is more rugged in a sense, more testing done.

Anyone have thoughts regarding this? Already got the motherboard and g.skill ram, now just waiting on the price drop.

[aamsel]

What version needed for VISTA 32?

you shouldn't need more than about 1.4 vfsb and 1.625 vmch. these were the values i used to get 9 x 400 with mem at 3-3-3-8 timings 1:1.

only other thing i can suggest you try is to put a fan over the NB assuming you haven't changed it out for something else.
