Live MB OC Report :: ASUS Rampage Extreme

I removed those washers and I changed the thermal paste and it is OK all

Sounds good Kimi, What temps are you getting now on the NB? and are you on air or water?

Temperature 65 degrees to air and with 1.65 of voltage on x48

Hi All,
Just had the stock cooling of the MB, and yes the TIM is the same on mine as on others shown.
Also noticed that on the bottom of the stock metalwork on the screw holes that there is a little black plastic washer of ~1mm thick, do you think that removing them after reapplying TIM would get better cooling results on the stock cooler?

A few points to note here, does the Asus plastic washer insulate the board from the springs ? - probably not if Kimi's is still working.

Secondly, if the screw are designed to bottom out in the heatsink then removing the washers will not compress the springs as much causing a reduction in contact pressure between the heatpipe assembly and the NB & SB chips.

Just my thoughts but I added a second plastic washer to increase the spring pressure and to prevent the screws from bottoming out if indeed they do.

So pester Asus to add DQ drive etc bios and the Micron based memory etc that may not work so well will stand a chance.

excellent insight as always Tony. this is what i was eluding to but didn't know what the issue was. but...why then does some Micron seem to have no issues...

1120MHz 32M stable at 8-8-8 is mighty nice and very much 790i like. is it possible that D9JNM is unlike D9GTS or the like and works well with low drive strengths?

Right, managed to get a chance to put 3rd party cooling on this board! I think this was mentioned by someone else between my last post about SB cooling and now, but I can confirm that the Enzotech will not fit - screws dont line up:



Not to be beaten, ive used a mix of AS5 and AS Adhesive in a square in the centre, surrounded by MX2 (so hopefully I can get it off again! LOL) ive used the old AS5/Adhesive mix trick a few times and not had a prob.

Anyway... here's my board as it stands:



Quick quetion - How important is it to cool the chips on the far side of the NB Power regs? i.e the ones that would be underneath the two ramsinks furthest away from the NB? Im using some thermal tape on the ramsinks which is working fine on all the others, but because of lack of surface area, those two keep falling off - I have an 80mm fan blowing over that area atm to be on the safe side.

How have u guys got your ramsinks on there? Used adhesive? I wasnt sure on such small chips that they would survive when u removed the ramsinks again when using adhesive.

MikeMK why cant you just angle the SB cooler a little to make the holes like up? as long as the Central part of the core is toutching the HS then it should be fine.

[MikeMK]

I tried it, and that wont work either - the holes are just slightly in the wrong place. I guess with a bit of modding you could prob make it fit, but im not guaranteeing that!

Here's a pic showing the Enzotech on the SB. THe video cards are in the way, but you get the idea.

Hi Rob,
I did remove those plastic washers and yes the screws did bottom out, and the springs were fully compressed, in fact from the back of the board it looks no different! So I will now have to wait and see as soon as i get the rest of the parts i need.

It is not because there isn't enough surface area over the NB MOSFETs. If you look carefully there are 2 small resistors that are slightly higher on the motherboard then the FETs preventing proper contact of the ramsink with it.


I had to use a plyer to slowly dig away underneath the ramsink to create a gap for the resistor. Becareful though that you actually make the gap high enough to avoid the resistor or you may bridge it when you stick on the ramsinks.

Weather you need to cool the northbridge's VRM is debatable, as the components there are quite capable of functioning at high temperatures. It doesn't run as hot as the FETs for the CPU, but hotter then those for the RAM. It tends to hover at around 60 degrees for the NB VRM, and the RAM FETs around 40 degrees. My theory is that because as FETs gets hot, it's internal resistance increases, so you will need to set higher values in the BIOS to acheve the same end voltage. It might be total nonsense, but never a bad idea to cool a hot component. You can see on many higher end DFI boards they have small heatsinks for the MOSFET of the RAM and northbridge.


Here is what I did on my Maximus Extreme NB MOSFET some time ago and trust me, the ram sink gets HOT!!:


I use a infared surface temperature thermometer to measure temps on the motherboard and see how hot each component gets:


And finally here is my current setup for NB VRM cooling:


The chokers and ML cap I left as is cos I don't feel they run as hot as the MOSFETs, and looks a lot nicer/tidier then burying the whole VRM area in ramsinks.

Have fun modding!

@EF: are those mounted with thermal tape?

[eternal_fantasy]

@EF: are those mounted with thermal tape?

Used what came with the ramsinks, so yes I guess.

[maxxx]

@EF: thanks for the response. Looks like I have to get rid of the stock cooling as well. Still aircooling though. Will see if those sinks are locally available here. Though the added washers seem to work, I think 3rd party coolers are doing a better job.

so far so good with the G.Skill 2x1GB 2GBHZs (D9GTR)...but CL6 clocks aren't what i am concerned with, it's getting over the 1030MHz bump that i interested in.

800MHz :: 2.00v | 822MHz :: 2.05v | 842MHz :: 2.11v | 860MHz :: 2.15v
With all this talk of D9GTR doing well I figured it was time to give it a proper shot and so far so good at CL6, but that isn't the issue with D9GTS. I still get the weird boot issue once in a while with the D9GTR kit and after putting them in, I couldn't get POST without removing a single stick, loading BIOS defaults, then POSTing. Then the second stick could go in and I could get POST. I didn't have to change anything in the BIOS, just POST with a single stick first and save & exit. Also, don't mind the LN2/Dry Ice container, the fan on the stock heat sink went so I am improvising

[eternal_fantasy]

3oh6, what was the limit of your G.Skill D9GTR kit in terms of pure frequency on any other intel platform? and I assume its limit on the RE is just under 1030Mhz?

on the Maximus Extreme they did 1034MHz 8-7-6 dual32m SPi but at only 2.00v DMM measured. i never took them over 2.06v back then as it was when we didn't know how much voltage D9GTR could take. if i remember correctly though, more vDIMM didn't really help get further i don't think because i have screenshots at CL6 & CL7 up to 2.06v. at CL6, up to 2.06v, they are clocking identical on the RE as they did on the Maximus Extreme. this is the first Intel board to see them since then.

as for on the RE, no idea as i just started working with them tonight and so far only at CL6. on the 790i they run single 32M at 1110MHz 8-7-6 2.175v DMM measured.

[eternal_fantasy]

Ah I see. Looking forward to your results!

[3oh6]

Ah I see. Looking forward to your results!

yeah the G.Skills aren't even booting into Windows at 1000MHz 8-7-6 on the 266 Strap at even 2.10v vDIMM. drop vDIMM down to 1.96v and the Ballistix go right into Windows and run dual32M with nothing else changed in the BIOS.

so my board likes my D9GTR even less than my D9GTS for high clocks

Thanks EF, I've got plenty of old ramsinks lying around to mod around here so I'll give that a go in the next day or 2. At least its gonna be alright to use the PC without them for a bit - that was my main concern - but like you, if it gets hot then I want it cooled! LOL.

[Clump]

Clump, in relation to my question a couple of posts back, out of interest how are you cooling all the chips by the NB?

I have a Thermal Take Spirit II Extreme on the NB. The stock cooler was removed entirely. There is a large copper colored heatsink over the power converters that I left alone. There's a 120mm exhaust fan right there, so there's plenty of air flow.

Not the best pic:

[maxxx]

@Clump, what temps to you get in the NB? (and voltage used please)... thanks in advance...

With the stock cooler my NB temps @ 1.39V were pretty bad, loading in the high 60s and sometimes 70+ and that was with 2 40mm fans kluged onto the NB heatsink. With the new cooler it's idling at the same temp as the motherboard sensor (50C atm) and loading up to 56 - 57. There's a triple rad dumping heat from the CPU into the case, so ambients in the case tend to be a bit higher. One of these days I'll reverse the fans to have the rad fans blow out of the case and make the rear exhaust an intake and see what that does. It's a pita flipping the fans though.

OCCT graphs 1 hour with stock cooler:



OCCT graphs 1 hour with Spirit NB and Enzotech SB:



Room ambients were within 2 C for these runs. The SB was actually better on the stock cooler, but there's no comparison on the NB.
