Happy new year

If you can tell me how to measure it i am actually taking my NB/Mosfet sink off now to replace the TIM...hoping to get the temps down ...i don't guess there is any magical way to measure it and i don't know if i have any measuring tools on me

On another note i just took mine off and the stock TIM looks looks like bubble gum...there was TIM all around the NB chip itself yet almost none was on the core of the NB...cleaning the TIM off now and installing AS5

Edit: Ok from what i can tell there has been a big drop in temps...i am adding .09v to my northbridge voltage so it will be comparable to a screenshot i took last night...for the record i am actually stable at around 1.30v i believe

Anyways i am going to do 50 runs of IBT which is what i had ran last night when i took the stock TIM screenshot and the NB temps where topping out at around 60C...keep in mind though my ambient temps where lower at the time

After 5 mins of IBT my NB is loaded at 50C....so considering the ambients its at least 10C cooler then the stock TIM

Edit: Ok here are the tests...i am pretty sure i used too much TIM as well as the NB Vcore is a little higher for the AS5 run

How clean did you manage to get it? The tape on the bottom is what frightens me as it will disolve the moment the cleaning solution hits it, however the regular tim is hardened and retardedly hard to scrape off.

Yawa -- I talked with MSI Tech and asked again about the NB temps. His response was this, "Yes, 80c is the max safe temp, but it would be best to keep it under 70c." Mine, when folding on both cards has gotten over 70c, so you are ok, but nearing the high side.

If anyone is going to be looking for 'other' cooling solutions to the NB, I will be putting my NB and MOSFETs under water soon, so I'll let you know how it works out, and what I used, because there are no pre-designed/packaged blocks for AMD 790FX chipsets. Ironically, there are a few options for 790i (nVidia) chipsets.

Definitely let me know how that goes, and yeah these boards can take a great deal of abuse.

Good question and SPEC, what's the best TIM to put on it? I wouldn't mind slapping some better Crap on mine!

I'm only running at 45-46*C @ full load with 1.30v on the NB Chipset, so I most likely don't need it.

Just so everyone knows, Even bumping the NB Chipset voltage by .05 can easily add a good 4-6*C.

I have my Stock CPU Fan Mounted right to the Section of the NB/MOSFET Heatsink that is directly above the NB Chipset. Also, with a side intake casefan that is angled slightly towards it (HS) to blow cool air right at the section above that, which is above the MOSFETs area of the heatsink.

It's seem to be pretty affective. I'll take some pics post them in a minute of it.

EDIT: PICS added of NB/MOSFET cooling

1.) This shows the side case fan blowing in from the outside.



2. the side case fan with the Panel open, showing the level of life from the panel to properly aim the airflow at the HS.



3.) Same fan but viewed from the top. Shows a better view of the difference of the angle.



4.) Shows the position of the Stock PhenomII CPU Fan over the NB Chipset section of the HS.



5.) Shows the difference in placement between the two fans and how the case fan directs airflow onto the MOSFET section of the HS.



So these two fans keep that sucker pretty cool and keep the loads temps down as well.

Ok. Taking off and reapplying the paste (even in a somewhat sloppy fashion) comes highly recommended from me. I have just taken apart my, and my girlfriend's future GD-70 just to see if they were about the same.

They are. It seems the thermal paste MSI used on these boards could not have had two worse things happen to them. Not only had the paste hardened to a rock solid substance, in both cases the the paste wasn't even on the chips, it had slunk off and hardened to the side of each one.

This certainly would explain the horrific temperatures I have experienced in my north bridge and south bridge.

Time to fix it.

-Removing the sink is not hard at all really. Just unscrew it from the bottom. I laid down the piece of plastic the motherboard came in and just flipped it upside down. The screws are tight, but not too hard to loosen.

-On the bottom of the sink when it is off. Be ready to use your cleaning product of choice, and what ever you do not use anything sloppy on the heat sink itself (you do not want to dissolve the sticky tape on the bottom, or maybe you do who knows, I just don't want you to do it because I forgot to tell you not too). Also be prepared to scrape the old TIM (You heard me right) SCRAPE it off the heat sink itself. It is mostly likely rock solid. Mind you, if you don't care about dissolving the tape, then by all means douse it in your cleaning solution of choice till your hearts content.

-On the chip treat it as you would reseating and reapplying TIM on your graphics card. Clean it off gently with a bit of solution then polish the north bridge and south bridge to a mirror shine. (Obviously take care not to short anything out).

-Reapply your paste directly on the chip (I used MX3) then holding the board sideways so the heads and the screws line up and the heat sink does not wiggle itself free from your chips, put a screw in the north bridge and then the south bridge so it stays in place. When they are in, flip the board back upside down and start screwing things down as even as possible making it as tight as possible (without damaging anything of course).


Is it worth it? Certainly if you were having the temperature problems I was having, especially knowing that 70-80C is the absolute upper limit the bridges should ever reach.

My North bridge and South bridge were both idling around 60C (Undervolted no less).

Now check them out...



Probably the easiest blind mod I've attempted so far on my new rig. I recommend it to ANYONE who bought this board. From what I read it's a chronic problem.

Very nice yawa! If we can get a confirm from someone else that this truly drops temps like that I will add to OP.

I realize now the folly in not taking a before picture .

I promise it works. Though I understand waiting for a confirmation. Another word of caution be VERY careful removing the old TIM from the heat sink, I was not exaggerating when I said I had to scrape it off (chip is more like it).

Good Deal Yawa!!!!

That's gotta be a good feeling knowing that you're in the safe zone.

I wanted to verify my finding first as well!

I ventured out and flashed to BIOS 1.84b and there is a pretty significant differnce in temps on th CPU, NB Chipset and motherboard readings. Let alone feeling more stable!

Here is a picture of my desktop at idle on the 1.7 Official BIOS. Compare the Bold print numbers of BIOS 1.7 to 1.84b

My Settings here were as follows:

1.) CPU @ 3400 (200 x17) @ Auto v (CPU-Z says 1.392v and 1.376v w/ Full Load)
2.) CPU-NB @ 2.6Ghz (200 x13) @ 1.25v in (BIOS) 1.26v (In Everest)
3.) Ram @ 1.6ghz (1:4) @ 6-7-7-21-28-1T @ 2.02v
4.) NB Chipset @ 1.25v
5.) HT Link @ 1.25v
6.) SB Chipset @ 1.25v

Check out the lower Rigth hand side of the screen for Idle stats. (SS was originally for my 5770 OC Records)




Now the Picture of my Current Desktop with BIOS 1.84b!!!!!!!!!!!!!

Settings are:

1.) CPU @ 3.8Ghz (200 x19) @ Auto v (CPU-Z says 1.392v and 1.376v w/ Full Load)
2.) CPU-NB @ 2.8Ghz (200 x14) @ 1.28v in (BIOS) 1.29v (In Everest)
3.) Ram @ 1.6ghz (1:4) @ 6-6-6-21-27-1T @ 2.02v
4.) NB Chipset @ 1.32v
5.) HT Link @ 1.25v
6.) SB Chipset @ 1.25v



What's the difference you ask.... Well, with BIOS 1.84b

1.) CPU is running 400Mhz Higher w/ same volts BUT is Idling 3*C LESS!
2.) CPU-NB is running 200MHz Higher w/ .03 Higher in volts!
3.) Ram is Running tighter timings!
4.) NB Chipset is running .05v higher BUT 4*C Cooler!
5.) After all of this, the Motherboard is even running 5*C Cooler!

Now I think that like E said, it would be BEST to have someone else confirm this first by flashing to the 1.84b BIOS and checking the difference in temps.

If someone wants to be proactive, then by all means go ahead. it will be interesting to see the difference on someone else's system... Just make sure to take before and After screenies as I did!

HERE is the link to download the 1.84beta BIOS.

Just click on the "Free Download" button.

Hmm that's fascinating I wonder what they changed in it.

Good for you though, seriously. I might try this tonight or tomorrow.

Yeah, it only takes a couple minutes to do with a USB device and M-Flash. Or through the USB device with the software on it.

Either way it a benefit. I'm just not sure if temps are lower or the BIOS are reporting them more accurately? Anyone have anything to say about this?


WHERE THE HECK IS EVERYONE??????

I get surgery done on wednesday of last week and come back to CRICKETS and TUMBLEWEEDS?
