Thanks to C-N for the Memory link
[QUOTE=C-N;2561489]Don't know how up to date it is as I haven't used it for some time but here you go http://ramlist.ath.cx/ddr2
Has anyone had experience with the Geil 2GB(2x1GB) PC2 9280 1160MHz Plus 4-4-4-12 2.45v Metallic-Orange Aluminum memory modules?
Their timings and rated frequency are very good, and I can order them for about $200. The problem is I am unsure what memory chip is inside them, and as this MB doesn't seem to like Micron D9 GKX chips, I want to ensure I don't end up with them again in my new modules.
My other choice would be the OCX Flex XLC PC-9200 2 x 1 GB modules, but they are about $80 more...
Ideas on Mounting additional cooling to Northbridge

I get nervous strapping something so top heavy and conductive so close to the video card
I am going to have a closer look at this myself over the next day or so. I just picked up a Thermalright HR-03 R600 VGA cooler for my ATI HD2900XT card, and need to mount it first to see what clearance issues it might create. I have a Swiftech MCX159 HSF and a Noctua NC-U6 HS in my "spares" bin, so I can trial fit them both. I will see what works best, and can give you all my impressions by about this time tomorrow.
I used to work as a mechanic and am pretty good at making things work. Unfortunately, unless a person is willing to just use cable ties to mount the HS on to the Northbridge, I don't see a way around having to remove the DFI heatpipe assembly in order to mount the HS on it.
The choices to properly mount the HS on to the top of the DFI NB comes down to two basic methods:
1) If a person uses thermal adhesive, it will create a permanent bond to the top of the NB cooler. This will allow very good heat transfer, but it is a PERMANENT mount. In addition, you would want to mount this with the DFI Heatpipe assembly off the motherboard because you would not want to run the risk of getting thermal adhesive stuck on the motherboard itself.
2) If a person mounts the HS to the Northbridge via machine screws and nuts, he/she will find that if the thermal paste was applied correctly the higher mounting pressures of using fasteners will ensure there is decent heat transfer. The added benefit here is that the HS will be able to be removed if necessary at some future point.
NOTE: The top of the NB cooler on the stock DFI heatpipe assembly has a protective finish as well as paint on it. It also has some stylized ridges that would probably need to be dealt with. In my opinion, if you were using thermal adhesive, you would need to at least sand the finish off the top of the NB cooler to give better grip for the thermal adhesive to adhere to.
If you were going to mount a HS with a flat surface using machine screws, then the top of the NB heatsink would probably need to be lapped to get rid of the little ridges that are on its surface. Otherwise, these little ridges would leave a pretty large gap that would have to be filled with larger amounts of thermal paste, and heat transfer would be adversely effected.
Initial inspection leads me to believe that mounting the Noctua HS with machine screws will work best for me. This HS has a lot of surface area and uses heatpipe technology. Because I have mounted my Thermalright Ultra 120 Extreme so the fan blows up through the CPU heatsink and out the top of my case, the Noctua HS assembly will sit just in front of the 120 mm Scythe fan, where it will get lots of airflow.
The tradeoff is that there is very little room to work with. If I ever have a fan problem or want to put a bigger fan on the CPU HS, I will need to remove the Thermalright Ultra 120 Extreme and my Scythe SFF-21F fan as an assembly first.
rationalization cooling NB on the our DFI /water
Hi, 92mm cooler on water cooling block CPU.
about 10`C lower on NB than without ..

About adding northbridge cooling...
I did my upgrade to the Thermalright R600 VGA cooler. While I had things out, I determined that the Swiftech MCX159U cooler was too large to effectively mount on top of the DFI NB cooler.
Then I looked at the Noctua cooler I had, and it will fit IF you have a Thermalright 120 Series cooler and IF you orient the cooler so its flat face is pointing to the top of the case.
I think the Noctua cooler would also work around something like a Tuniq Tower 120, but again that would be IF the cooler was oriented so that the fan pointed towards the top/bottom of the case.
What I did instead was mount my fans at the top/back of case so they are bringing cool air into the case, and then flipped my PSU so its 140 mm fan draws warm air from the bottom of the case.
I also used the DFI copper plate sandwiched between the CPU and HSF and mounted the Transpiper assembly off the PWM at the back of the case.
Doing this has reduced my load temperatures in Prime95 by about 5 C, and my idle temeperatures have dropped by about 6 C. In addition, my PWM temperature is now about 12 C cooler at idle AND under load.
So, all in all, I am pretty happy with things as they are, and will no longer worry about adding an "extra" heatsink to the NB.
