Here are the pics of the heat pipe taken off and the paste/contact. Also readings before and after reapplying. It looked pretty good to me. I replaced the tim, but I think tightening the bolts on the sinks did the most good for the temps.

So quick question. If I wanna pull off the North bridge heatsink to water cool it, I gotta take all of it off? Is the whole thing connected or can you take off one and not the other?

[turtletrax]

The heatpipe is all soldered together. If you want to WC the NB, you have to find replacement heatsinks for the SB and PWM.

Sucks, I know. but just be thankfull the stock cooling actually works

I wish i could rotate my Ultra eXtreme like that. Don't have any room in my case for such a feat..

Ah damnit, was not counting on having to get cooling options for the south bridge and the PWM. Have no idea what I'm gonna use for cooling those parts, gonna have to do some reading. Anyone have any proven suggestions for after market air cooling the south bridge and the PWM?

[turtletrax]

Not sure about the SB but the PWM I would look into the HR-09 S TYPE 2.

I guess you could always put the HR-05 (which ever one works best for you) on the SB.

[nzbleach]

PWM does not need any extra cooling guys, Its not even warm to the touch after thrashing my CPU, VTT, and pretty much all voltage controls to near max during benching. My ambients are near 30 degrees aswell. I'm not using a transpiper, and I have the non-heatpiped P35 LT board.. Good case air flow is all you need. Chipset is a good idea to have some direct airflow over, or replace with something aftermarket. Southbridge needs nothing. I dont understand why people raise SB voltage more than 1 notch, it will do nothing for your OC.

Is this the absolute and ONLY change? This bios is running so well for me I would hate to have anything else changed that could bugger up my stability. If an updated Matrix version is the only change I may give it a shot. Where did you get the latest version and who exactly did the mod? I wonder why DFI themselves didn't include this in the bios.

Yes this is the absolute only change, me and a VERY TRUSTED freind of mine used a piece of software called CBROM (http://www.ryston.cz/petr/bios/cbrom111.pdf) which is a bios editing tool, used it to update the Matrix ROM in the bios from version 7.5.0.1017 to 7.6.0.1011.

First used the cbrom ***.bin /d command to see the diff modules
then used the RELEASE command to release the PCI rom for the RAID
and replaced it with the 7601011 rom
Renamed the bin file to 1.bin for ease
cbrom 1.bin /d
cbrom 1.bin /pci RELEASE
cbrom 1.bin /pci 7601011.bin
and then checked to see if it was really there
cbrom 1.bin /d
Renamed the bios file back to LP35DC24-mod.bin

The only reason I will not flash it myself is because I only have the one bios chip, I would only recommend this to someone who has a spare, so if it did go wrong they could swap it out and then maybe hot plug / flash the buggered one.

This is the link to the bios file: http://www.mediafire.com/?bydfm9z1dgk
If you do choose to give it a go, please report back so I will know wether to flash it myself or not.

This RAID ROM Version is all over the internet, I dont know why DFI havent chosen to add it into their bios, after all they added the ACHI one, however all other top motherboard manufacturers appear to be adding it themselves, Intel, ABIT, ANUS, MSI etc.

good to know, I've never added any Vs to the south bridge but I was only guessing that they needed some type of cooling. I may just add some mosfets just to make it look cool then lol.

[C-N]

PWM need a 1/2 decent fan with quad, dual cores dont push the PWM so hard.

[mrcape]

Yeah it's not worth removing the heat pipe, just tighten the bolts on each sink and point a fan at the nb.

Good to know but I just got done relooping I would have tossed an MCW-30 on there. Next time I guess.

[mrcape]

Well with most stuff set to auto I got my e6600 to 3.7 9x411 4 4 4 12, and really stable and swell at 8x450 and 9x400. the most vcore was 1.42v. That's enough for the first night. I want to go to Boston tomorrow and grab an e8500.

I'd still love to see some dual core bios settings so I can see how you guys are getting it done. I looked at Evas which are great but they are older bios.

[Darkmind]

I'm removing it as to add a water block. Seeing as I wanna see some high FSB and I'm gonna water cool this build i'm working on it seems only right to water cool the NB.

This is my build log: http://www.xtremesystems.org/forums/...d.php?t=173936

Adding a good thermal compound (MX-2, AS5) would also help a lot.

Hey, Warren You ever send that board into DFI?

Nah man. DFI policy on RMA is the suck. Asus will take back a board for three years and replace it. DFI gives you 90 days to exchange then only offers to repair it. That's hardly a decent policy IMO.

I don't want a God Damn Repair I want a New board. How the hell are they gonna repair it? They'll just waste my time and send it back and say there was nothing wrong..total BS.
So I just live with it.

I got that word from MotherBoardPro...and me a "reseller" too... so much for special favors...

It works...just resets once in a while. And since I am running a single drive the RAID issue is a non issue.

If I do build it back up to run at the benches it will be a suicide run...

I have been running my boards 24/7 100% load for YEARS. I've been Folding since 2005 and before that ran SETI. This is the first board I've owned that resets at stock speed. I know you love you some DFI but call a spade a spade man...My P5K Deluxe is functioning flawlessly 24/7 100% load 3.6 ghz for almost a year now.

In fact I have never had an issue with Asus. But I have always found the DFI boards to be twitchy. They are great performers and balls of fun to OC...but not what I would reccomend for ultimate stability in an OCed desktop PC.

Adding a good thermal compound (MX-2, AS5) would also help a lot.

That's what I did in the pictures above, removerd everything, cleaned with arcticlean and replaced tim with Shin Etsu TIM. I did get 4c lower cpu, 7c lower PWM and 6c lower NB temps.

The thing that skews the temp data I got is that the screws on the NB sink weren't tight when I did the tests at first. Once I added new paste and tightened NB sink I got two great things - better temps and clearance to put the Ultra 120 vertical.

Is a hang on the logo screen common? I think there's a pattern to it but I can't quite figure it out.

Here's the symptom -

1. Go into bios with stock bios settings
2. Change settings to get your overclock
3. Save and load new settings
4. Loads new settings, boots into windows and works fine
5. Restart, hangs at logo screen
6. Another reset when stuck at logo screen and it loads fine

Anyone experience this? Just want to be sure it's part of the cycle and not unstable.

[Praz]

Most likely NB, VTT or memory voltage too low.

[mrcape]

Most likely NB, VTT or memory voltage too low.

Thanks! I guess I'm still trying to get the right balance of those. Will orthos blend and large fft be a good indicator of stability? I did some 5 -10 minute runs of those and everything worked fine, that's why I was confused by the hang. Maybe I need to let it run a few hours.

Right now I have set -

CPU - 1.41
VTT - 1.35
NB - 1.45
Vdimm - 2.09

e6600 / Gskill 6400 HZ

Thanks!

Assuming you're running 400x9 the voltages should be plenty. Might try increasing then one at a time and see if one solves the issue. A quick check if NB voltage is the issue is setting PL. Set it one higher then it is currently set at and see if the hanging at boot stops.

Thanks Praz, I'll try that. Also, thanks for keeping the thread up with that new bios info.

You made a big mistake parting out your P35/intel rig for an AMD rig.

Why? I am very happy with this AMD board. Now if I idn't have this Raid Card and had to use the onboard controller yes that would cause me to shoot myself

5-10 mins run of prime doesnt even pass the first test completely, and definatly does not signify stability, you need at least 8-10 hours run, the first set of tests (1024) is the easiest run out of all the tests that prime runs.

It takes Prime approx 9-10 hours, to run all the tests from 1024 (8k being the smalest) through to 4096, and then start from the begining again, if your just using your machine for everyday basic things then one loop should suffice, if your designing rocket parts for NASA's Shuttle then 1 weeks worth will be in order.
