Looking for a chipset which can have a high FSB yet low RAM

First, the setup:

ASUS P5B i965, S775, PCI-E (x16), DDR2 533 / 667 / 800,
Intel Pentium D 805 Socket775 , Smithfield Core, 2x2.8 GHz , 2MB Cache, Retail
2x1Gb PC2-5300 DDR2 533MHz @ 667
256MB Palit 7600GT Sonic, PCI-E(x16), Mem 1500MHz, GPU 575MHz, 12Pipes, D-Sub/Dual Link DVI/HDTV SLI
250 Gb Maxtor STM3250820AS DiamondMax 21, SATA300, 7200 rpm, 8MB Cache, 11 ms
Coolermaster Aquagate Viva Water Cooling Kit
600W EZ-Cool Silent pPFC Power Supply PCI-E + SATA AMD & P4 Ready 12cm Silent Fan ATX12v Ready
XBlade Silver Ultimate Gaming Case With 450W PSU & Side window
NEC AD-5170A-0S Silver x18 DVD±RW Dual Layer DVD-Writer OEM UK

Normally hit a 3.8-4.2 OC pretty easily, but the thing which is maxing out is the RAM. The lowest divider the 965 does is 1-1, so I was wondering what other chipsets could be used instead?

This is a setup for customers, so price is quite a big factor. Of course if it can be justified...

The nvidia chipset boards can do it...

680i and 650i, they allow for unlinked mem and fsb settings so you can clock your ram lower than your fsb

Hmm, ok. The only problem is the 650is low max FSB.
