Sparkle Computer has pulled another Doctor Frankenstein mode and managed to make a full line-up of GeForce 8400 GS cards that feature not AGP, PCI or PCI-Express x16, but PCI-Express x1 connection interfaces. No less than eight PCIe x1 cards are prepared by Sparkle and they have either 256 or 512MB of onboard memory and make use of active or passive cooling systems.

Apart from those mentioned, the SX84GS256D2LE-HP, SX84GS256D2LE-HPP, SX84GS512D2LE-HP, SX84GS512D2LE-HPP, SX84GS256D2LE-HM, SX84GS256D2LE-HMP , SX84GS512D2LE-HM and SX84GS512D2LE-HMP all feature the same clocks - 567 MHz for their GPU, and 900 MHz for the shaders and memory, have 64-bit memory interfaces and offer both DVI and D-Sub outputs.
