The 2 Gig Ram Question/Issue

Question

So MSI tested this board and rated it to support 2 Gigs of RAM but the biggest stick tested was 512.  That means that the most you could hope for would be 3X512 and that ain't 2 GIGs.  Here is the MIS link to memory modules you may want to reference:

Here is the exchange I had with the OFFICIAL tech support guy at Corsaire:

I have these two:

I have 3 memory slots (2 currently occupied), but I can only have 4 banks total of memory to stay at 400 mHz FSB. I want to add this stick to take me to a gig of RAM:

This would then occupy my 3rd slot giving me over a Gig of RAM. This is my setup:
K8T Neo FIS2R Bios 1.7 (made by MSI)
Athlon 64 bit 3400
2 X 256 Corsaire XMS PC3200LL
Slots 1 & 3 (timings: 2-3-2-6) [2.7 V]
Antec Tru Power 550
Windows XP Pro
*added*
I have ver. 1.1 I believe.
also, I can run 4 banks and still have 400 FSB. I am pretty sure that the sticks I have now are only 2 banks total. So the stick I want to buy CANNOT be more than 2 banks but should be safe.
MIS and my board have major issues with Corsaire. Many are told to steer clear, but I already own two sticks and they were expensive and I will be damned if I have to go with something else. Here's my rig:
K8T Neo FIS2R Bios 1.7
Athlon 64 bit 3400
2 X 256 Corsaire XMS PC3200LL (Twinx)
Slots 1 & 3 (timings: 2-3-2-6) [2.7 V]
this is exactly what my RAM sticks say:
CMX256A-3200LL
XMS3205v1.1
0308120

You would need to match the module exactly to what you have now only CMX512-3200LL Rev 1.1 The Pro version will not work in this MB with the modules you have now! Sorry! The other choice would be to find another use the memory you now have and just get a Twinx1024-3200LLPro instead!
Look, I just want 2 Gigs or 1.5 gigs of RAM and I want to run it at CAS 2 like I am running right now.  The KingMax RAM is CAS 3!  Other than Kingmax and Apacer (the Crucial 512 stick is not at Newegg) the other RAM ain't available from Newegg, so where am I supposed to get this RAM from.  And the Apacer is CAS 3 too!!!!!

ah but what about using 2, 1 gig sticks.
that will get you 2 gigs of ram and using only 4 banks should allow the speeds to remain at 400, when you use 3-512's you usually have 6 banks which the mem controller doen't like and gives you 333.....
really, it's 6 banks?1 damn.  I'll have to scrap that. and yet 2 one GIG sticks are still only 4 banks??
aside from what the poster right below you has, what do you think about these two sticks:
