HD 4870 CF on P35 -- P45 --X48 Chipset - OCF Testing


So there has been a lot of people asking about how much CF (Cross-Fire) on a pair of high end HD 4870's will be impacted by dual x4 , dual x 8 and dual x 16 PCI-e lanes.

I will be starting to test just that late this week so we can see just how much the various chipsets and lanes impact and potentially bottleneck 4870 CF.

System Spec:

CPU : Q9650 (450 x 9)
RAM : Crucial Ballistix D9 DDR2-1066, OCZ Platinum DDR3-1600
GPU's : 2 x Visiontek HD4870

Motherboards:

GA-X48T-DQ6 - Intel X48 Chipset - Dual x 16 PCIe 2.0 slots

ASUS Maximus II Formula - Intel P45 Chipset - dual x 8 PCIe 2.0 slots

GIGABYTE GA-EP35-DS3P - Intel P35 Chipset - Dual x 4 PCIe slots

CPU will be a 45nm quad.

I will only run at 1680x1050 and 1920x1200 res and a couple of synthetic benchmarks and a few gaming benchmark, not too many as it takes too long to report on the results.
