KT400 Conspiracy??

[AlphaFox]

I have a MSI KT7V Motherboard.
I have DDR3500 from Corsair
I have a Athlon unlocked / FSB 166
With this combo, you cant run the CPU FSB at 166 and run the memory at 200. according to MSI, its a 'chipset limitation' as indicated in a tech doc. on there site. e-mailed tech support and they said 'with a fsb of 166 you cant run memory at 200' bluntly.
Does this go for ALL KT400 motherboards?? if not which boards allow this, or is it realy at 'chipset issue.' if another MB manuf. that uses the KT400 can do it, the its just the MSI boad that has some issue. please help me out here.

this motherboard DOESNT support DDR400 with FSB @ 333 according to "tech support"
MSI SUCKS!!!!!!!!!!!!!!!!
chipset problem my @ss, they just dont know how to make motherboards. AAAAAAAHHHHHHHH!!!!!@#$@#$@#$ @#$ @#$ @# $

I'd like to support Wusy with this. I'm not a big fan of samsung in general. Winbound and Nanya were 2 of the first companies to release DDR 266 (PC 2100) RAM with CL 2 (CAS Latency of 2.0, rather than 2.5).

It seems a good idea to trust Winbound with memory vendoring over samsung.

If it is a chipset issue, NO board will be able to support this. It is a vendor issue, you may want to try and get a refund on that MSI board and go for ASUS, or Abit.

I thought that with both the KT333 and 400 memory support was asynchronous with the FSB up to 166, beyond that it had to be synchronous.

Thus you could have 266FSB and 333 or 400 memory, but with 333fsb you could only have 333mem

Probably.
One has to realise the benefits of PC2700 to PC3200 are limited at the best of times if the system bus is stuck back at 133Mhz.
And it worse when PC3200 can't be ran at the same hard timings as PC2700 due to signal intregrity.

Ive also heard that the KT400 has hidden memory timings that are more lax when a memory speed of 200mhz is selected.

for this board at least, no, you cant asyncronously set the fsb and memory past 333.

the Corsair ram is supposed to use winbond anyways, so im not sure what your referring to as far as memory instability.

I am running wiht the tightest timings now and get around 2450 - 2550 in sandra for memory speed. not that bad. if fsb is 133 and ram is 400 its horrible, less than 2000.

oops, your right. its a KT4V (MS-6712)
tech sup. e-mailed me back saying that the KT400 chipset didnt support a FSB higher than 333 thats why it wouldnt work. Im not sure this is true, ok officiall it doesnt support 400 fsb, but im sure if they only allowed asyncronous operate past 333 it would work.
