The Maximus Formula Thread - Help/OCing/Guide/Rampage conversion

Just removing and re seating your NB will lower the temps about 5deg I bet, they aren't set very well stock. Also if you have the Std edition Formula without water cooled NB then your SB is gonna get hotter being in that heat pipe with the NB, its better off without being attached to the NB pipe.

I have just a heat spreader on my SB and its running around 34-38 where as before when it was on the heat pipe with the NB it was running 50, same as the NB temp.

Ewwwww shame on you Asus. That is horrible design. Why would you punish the SB with teh NB high temps by putting it on the same heat pipe.

[Prodigys]

Northbridge :

Ambient = 25.6°C (PC + heater = warm room )
NB temp = 33°C STRESSED
Voltage NB = 1.57V
Cooling = P5E stock cooling + 120mm fan pointed on it

Mods done : did a extra twist on the mounting screws that's it...

(Besides that, I'm running 445 x 8 on AUTO settings again, and it's now 5 hours prime stable. But 445 x 9 gives me after 5 min a error...)

Could this be the CPU ? He did 4Ghz on 1.40Vcore, and on 1.42Vcore he was 3DMark stable...

So the NB can handle the FSB, also the CPU can handle so far 475 FSB.
But high speeds give me lockups, so I think PLL or GTL ref is not good, am I write ?

[Robin77]

Yes, 96C.

The Northbridge is sensitive and can become damaged if it reaches over 54C with high overclocks from my studies.

The Optimized temp for the X38's is 40-45C, If you can get lower then that, Then

Than you had low quality boards for your studies. My NB runs even idle on 67 C and my PC runs round clock (cause of downloading ;-)). I've not a single stability issue or even anywhere near.

As said, look at what Intel says what is the max temp (96 C) and look again what I wrote regarding my NB tems and the rockstability with it. Believe me, if you get issues with low NB temps of even under 60 C then you should really RMA your board, because the NB is built to run rockstable up to 96 C. This is not a peakvalue for jus 1 sec or so, it's the max. value for longtime usage.

The Thermal Letter is alot different then real world performance. Just Like CPUs. Just because the Thermal Letter on a Q6600 G0 is 85C doesn't mean you'll get the same performance from the CPU running at 80C then 30C. Because Ultimately for any Computer Technology, Cooler is better.

My Studies are also based of what I've seen from other people and reviews. Unless you are running a 3.8Ghz - 4.0Ghz+ Overclock, I wouldn't call your answer "rock solid" lol

I've never understood this trend towards a roller coaster heatsink design. It's just awefull, but they have made it too hard to go 3rd party now and get everything covered without cutting up the stock sink. I just keep fans blowing all over the entire board at this point.

[iadstudio]

what's the safest way to get the NB heatsink off? I did the freezer ,ethod on one board, but I'd rather not do it again as I think that damaged my VIA firewire chip.

[xgman]

In bios 907 if I set my cpu "pll" voltage to 1.7v, in hardwrae monitor it reads over 1.8x volts in red. Anyone else see this over volting?

yep. the board overvolts the pll and just about everything else.

[xgman]

Well, except the vcore which droops a little. Actually, I just saw that my question was answered in the 1st page of this thread. I've never noticed if all recent asus boards overvolt cpu PLL, so should I set it to 1.6 to get 1.7 if I'm used to running other asus boards at 1.7v PLL?

Hi all,

I have just got 8gb of OCZ reaper memory with spd of 4-4-4-15 at 2.1 800 mhz I set this but my system is very unstable in games. Its weird becasue it can run prime etc all day just no games. Anyone else experiencing this and have a workaround? I have fiddled with all voltages so I dont think that will help.

Whatever you say. I find it a little bit confusing, when I have 67 C idle and far above 70 load temp on NB and I run my 6850 C2D rockstable @ over 3,9 GHz. I'd call this a proof that at least in this case the Intel engineers know more about technologie than you.

What you do is to make people think omg my NB temp of lets say 55C will destroy my Mainboard and maybe my whole PC. This simply isn't anywhere near truth and facts profe it wrong.
So I think it's important for keeping up the level of this forum to post facts where there are facts and mark "I think, and out of my experience" things as such and not as facts.
If that wasn't your intention than it didn't come clearly enough.
But I will tell you when my NB should burn far far away in future.... ;-)

I have experienced something similar with a pair of G.Skills 4Gb set. It passes memtest and prime95 blend for hours but I found that doing a CRC check (with .SFV files) show randomly corrupt files.

At first I thought my partition was corrupted or the HDD was failing, but the same data checked on another machine resulted in no errors found.

I lowered the timmings, upped the vmem, set bios at default, nothing helped. The most weird thing was that each time I did a SFV check (on big rar files) a different file resulted in checksum error. Not the previous one that had errored out.

So thinking my Gskill sticks were bad, I installed them on a G33 gigabyte motherboard and there was no CRC checksum errors whatsoever (on the same set of RAR files). Even on their stock timmings of 4-4-4-12.

So I believe that either the BIOS subtimmings on the Maximus are too stiff or there is some incompatibility with these sticks. I also tried BIOSes 505, 802 and 907.

Im currently running my mobo with a pair of cheap Gskills 2Gb 5-5-5-15 kit without problems.

Have we not had this useless argument b4?

Can you post your "FACTS" and then this argument can be put to rest

[Zucker2k]

I'll be scared sh*tless if my cpu idled at 67, much more my NB.

My NB temp is ALWAYS lower than my cpu even though it is after my cpu in my loop.

[Sources]

I'm pretty sure that is already a fact that electronics produce better results when under load keeping lower temperatures. =P

Ummmm I was worried when mine idled at 52, yet alone 60 something, LoL

It's all about the heat gun. Here's a recent post on [H] I threw up on the issue. There's some pics of my setup which show echo...

I just keep fans blowing all over the entire board at this point.

...that.

The power sinks are fine, but I would like to see pipes come from the board to the right side and then fin out like an HR-05. That would keep them off the boards and out of the way of add in cards/cpu coolers. Ideally, they would blow up and exit from the top/rear of a case.

[CERO]

Mine board is sold 2day, so I am leaving this part.... I am waiting for the rampage.

[binormalkilla]

I would suggest throwing a fan in front of your memory/NB. I just angled mine against my PCI-E1 and my 24 pin ATX so it hits the memory and the NB, and it dropped my NB temps from 52-55 to 40-43! I pretty much idle and load at the same temp now.

[iadstudio]

antec spot cool on low brought my NB from 55c to 42c

Download PCPROBE from ASUS:

ftp://ftp.asus.com/pub/ASUS/misc/uti...eII_V10429.zip

and OCCT for stability testing:

http://www.ocbase.com/download.php?fileext=exe

Run PCPROBE to monitor your Northbridge temps. Run OCCT on Infinite mode for a minimum of 12 hours. Post your sceenshot as proof of your claim.

EDIT: I'm really intrested to see this screenshot.

[theonlybabyface]

I'm running 4 X 2GB G.Skill PC 8000 with no issues. This is the best board I've ever had. Easiest overclocking too. Others have had nothing but trouble. Good board/ Bad board? Or Extreme users being too extreme? Maybe a combination? Build it. Run it. You'll love it or RMA it if it doesn't work with known good components. Isn't that always the case though???

Hey WFO,

Just picked up 8GB's of the same ram. Care to share all of your settings with me?

[pazza316]

Ultra Nexus what subtimings does the G33 set? Could you take a memset screen shot for me?

Thanks
