Soltek has announced that its mainboards powered by Intel’s previous-generation chipsets now support 800MHz Quad Pumped Bus despite of the fact that originally the devices only provided 400MHz and 533MHz QPB.

Thanks to Soltek’s BIOS department and R&D efforts, SL-85DR-TC, SL-85DR2-DC(L),  SL-85DR2-TC as well as SL-85LIR-C(L) mainboards based on i845D, i845E and i845GL with ICH2/ICH4 I/O controllers, are now able to provide PSB overclocking of up to 800MHz Quad Pumped Bus. No idea if Soltek actually makes any warranties or no, but, at least, those of you, who already have one of such mainboards and plan to buy a shiny new Intel Pentium 4 processor with 800MHz Quad Pumped Bus, now can try everything out.

As far as I remember, i845D and i845GL cannot support Intel Hyper-Threading technology, hence, the only performance boost you will get will be from higher FSB speed. Note that it will not be really substantial since the chipsets only support single-channel DDR SDRAM PC2700 or even PC2100, so, there are doubts that you will ever notice any speed gains with such upgrade except boosts from higher clock-speed of a CPU. Keeping this in mind, there is practically no sense to buy new Intel Pentium 4 2.40C, 2.60C and 2.80C processors for such mainboards. Also you should remember that not all outdated mainboards can support 3.0GHz processors and above because of inability to provide sufficient power for these CPUs.

PS. Any i845 with PC133 SDRAM mainboards with 800MHz Quad Pumped Bus support?
