Overclocking and Thoughts
With a maximum of 1.5875V Vcore available to feed the 3.4 Extreme Edition (up from 1.5V standard), maximum speed testing was never on the cards. So I turned to the PF4's working multiplier adjustment for the ES CPU, keeping the target speeds on or around 3.4GHz while dropping the multiplier and upping the front side bus speed.13 x 260 for 3.38GHz (DDR692 @ 1.90V) wasn't a problem with the unstable limit hit at 263MHz, with the CPU at a shade over stock voltage at 1.525V.
Retesting ABIT's AG8 with the most recent BIOS shows a similar front side bus ceiling, so the PF4's potential for overclocking using Prescott CPUs and good cooling is there. More than applaudable and ECS not getting stung by the supposed clock limit on the new core logic.
Thoughts
Excellent performance, a nice BIOS, brilliant extra hardware and software bundle, great features (including HD Audio and Matrix Storage), sensible layout, good overclocking. What's missing? Ah yes, price. At just under £105 including dreaded V.A.T in the U.K., it's the same price as an ABIT AG8 and significantly less than the DDR-II toting ABIT AA8 DuraMAX, with better performance, features and a better bundle. That's not all. It's nearly £50 cheaper than ASUS's DDR-II Grantsdale board which has a comparable feature set. Providing you've got no trouble investing in DDR-II memory, the ECS PF4 Extreme looks to be the best LGA775 mainboard we've yet tested at HEXUS, by quite a distance.I'm struggling to fault it, bar being slightly annoyed it didn't have more Vcore range for the 3.4 Extreme Edition I use for testing. Given the number of those on the market, does it really matter?
Like the AA8, AG8 and ASUS's boards, the PF4 suffers from the downsides of the new Pentium 4 platform. Short supply of graphics cards and CPUs to fit are the main problems, but with DDR-II starting to come into its own in terms of overclocking and tempting prices. I still can't really recommend the platform because of those issues.
However, if you're keen, slap the PF4 Extreme at the top of your shopping list, because ECS's Computex promise seems to have carried over to the boards that are reaching retail.
Excellent stuff. Snag one from Protac (phone sales only, ring 08701 205370) until ECS sort out some more U.K. resellers. Non-U.K. readers, pester your local hardware vendor.
