ASRock P67 Extreme4
Always striving for the best apparent value, ASRock loads its P67 Extreme4 with three PCIe x16-length slots and four SATA 6Gb/s ports, plus dual USB 3.0 controllers to address both front and rear panel needs.
Yet, the extra features aren’t completely without at least some minor compromise. The third graphics card slot, for example, is limited to four pathways, while the other two switch from single x16 to dual x8 connections whenever a card is added to the middle slot. An eSATA port is also shared with one of the added SATA 6Gb/s ports, so that builders must decide whether or not to sacrifice eSATA for the sake of an extra internal drive.
A PLX controller keeps onboard PCIe devices operating near full performance levels, while an ASM1083 bridge adds PCI support.
ASRock knows that Windows XP hasn’t been completely abandoned by the gaming market yet, and those few holdouts can get AHCI support during OS installation thanks to an included floppy port. That port comes free via the Multi-I/O controller, while the added-cost Ultra ATA connector is instead removed. We suggested this move a few years ago when Vista’s performance problems made the elder OS desirable, but Windows 7’s improvements have significantly reduced the XP market. The presence of this connector in such an unobtrusive location doesn’t bother us, and the pin cost is insignificant.
There’s very little in the entire P67 Extreme4’s layout that we could criticize, though the bottom-rear-corner front-panel audio connector is still inconvenient for the connections of some cases. More worrisome for those considering a triple-card CrossFireX configuration is that every front-panel cable end will block the insertion of most performance-oriented graphics cards. Determined builders can usually force the card to the bottom by using the side of its cooler to smash front-panel cable ends flat, but we’d rather not tempt fate.
ASRock was the first to respond to our industry-wide pleas for a “universal” front-panel USB 3.0 port, and had already taken us up on the suggestion to include both drive bay and slot panel brackets. The company has further improved the P67 Extreme4’s installation kit by adding a 2.5” drive tray to its front-panel bay adapter.
I'm just missing benchmarks like SATA/USB speeds etc. Please Tom's get those numbers for us!
1. SLI "support". Do not understand why end-user has to pay for mythical SLI "sertification" (all latest Intel chips support SLI by definition) and a SLI bridge coming with the board (at least 75% of end users would never need one). The bridge should come with NVIDIA cards (same as with AMD ones). Also, in x8/x8 PCIe configuration nearly all NVIDIA cards (exept for low-end ones) will loose at least 12% productivity - with top cards that is about $100 spent for nothing (AMD cards would not see that difference). So, If those cards are coming as SLI-"sertified" they have to be, in the worst case, equipped by NVIDIA NF200 chip (though, I would not recommend to by cards with this PCIe v.1.1 bridge). As even NVIDIA GF110 cards really need less than 1GB/s bandwidth (all other NVIDIA and AMD - less than 0.8GB/s)and secondary cards in SLI/CrossFire use no more than 1/4 of that, a normal PCIe v.2.0 switch (costing less than thrown away with x8/x8 SLI money) will nicely support three "Graphics only" x16 slots, fully-functional x8 slot and will provide bandwidth enough to support one PCIe v.2.0 x4 (or 4 x x1) slot(s)/device(s).
2. Do not understand the author euphoria of mass use of Marvell "SATA 6G" chips. The PCIe x1 chip might not be "SATA 6G" by definision, as it woud newer be able to provide more than 470GB/s (which is far from the standard 600GB/s) - so, I'd recommend to denote tham as 3G+ or 6G-. As it is shown in the upper section, there is enough bandwidth for real 6G solution (PCIe x8 LSISAS 2008 or x4 LSISAS 2004). Yes, will be a bit more expensive, but do not see the reason to have a palliative solutions on $200+ mobos.
