Asus Blitz Extreme P35 Socket 775 Motherboard

Introduction & Specifications

Introduction & Specs

Back in June Overclock3D was given the opportunity to sample one of Asus' very first Intel P35 chipset based motherboards. Continuing the naming convention of many Asus predecessors, the P5K (DDR2) and P5K3 (DDR3) were both rock solid performers and managed to obtain several awards during our tests. In addition to this, both motherboards gave Asus a good chance to get to grips with Intel's latest chipset and the impending DDR3 technology.

Today we're back again, but this time looking at Asus' latest motherboard in the "Republic of Gamers" (or ROG for short) lineup. Based on the P35 chipset and utilising DDR3, the catchily named "Blitz Extreme" motherboard intends to build on the success of the P5K3 series whilst also adding plenty of extra features and performance tweaks synonymous with the ROG brand. For those of us who haven't made the jump to DDR3 yet, Asus have also created a DDR2 counterpart named the "Blitz Formula" (who thinks of these names??).

Anyway, enough of my ramblings, lets see what Asus have to say about the Blitz on their website:

The Blitz Extreme motherboard provides awesome Overclocking speeds and challenges performance limitations. Equipped with the innovative Crosslinx technology for increased performance, it utilizes the Fusion Block System - an effective 0dB fanless design cooling system with a chipset waterblock that adds onto a power user´s existing watercooling circuit to help keep operations cool. Additionally, SupremeFX II not only increases the sound quality, it also enhances aesthetic value. The Blitz Extreme also adopts the Intel P35/ICH9R chipset and supports cutting-edge DDR3 dual channel memory and CrossFire Technology - making it the Overclocker and Gamer´s first and best choice.

The Republic of Gamers consists only the best of the best. We offer the best hardware engineering, the fastest performance, the most innovating ideas, and we welcome the best gamers to join in. In the Republic of Gamers, mercy rules are only for the weak, and bragging rights means everything. We believe in making statements and we excel in competitions. If your character matches our trait, then join the elite club, make your presence felt, in the Republic of Gamers.

Two main features that seperate the Blitz Extreme board from some of it's P35 based counterparts are Crosslinx and the Fusion Block System. Firstly, Crosslinx is a technology designed by Asus to alleviate the performance issues when running Crossfire (2x ATI cards) on a P35 chipset motherboard. By design the P35 chipset is only able to run the 2nd PCI-E slot on the board at 4x (electrical), thus creating a substantial bottleneck and dramatically reducing the performance of the Crossfire configuration. Crosslinx reconfigures both PCI-E slots to run at 8x (electrical), greatly improving performance and allowing Crossfire to function without any issue.

Next is the Fusion Block System. Essentially a water block placed on the NorthBridge chip, the Fusion system also has the additional benefit of being connected to the SouthBridge, Mosfets and Crosslinx chip via heatpipes. Obviously you'll get a chance to take a look at this yourself later on in the review, but it's good to see Asus implementing new cooling techniques to keep the core parts of the motherboard cool and in turn aid better overclocking.

With these two main features out of the way, let's take a closer look at some of the more detailed specs:

they've taken there previous motherboards, and just tweaked them to make them slightly better, added a higher pricetag, and shoved it on the market, genious really

oh, and great review

I think ASUS fans will like this especially, for the reasons ionicle states. Though it does imply that this latest tweak will allow u to get that much more % of an oc.

Outside of this review, I`d like to see a study where some1 takes 1 set of a full pc hardware install, and install the OS on it a large number of times. Each time take the benchmarks like XMS has used, and find out how much a difference u get in terms of a % each time. It`ll be small, I`d think, but it would add proof to my thinking that one board beating another in a finite benchmark doesn`t necessarily mean anything, unless it goes over a %.

My theory being, u build a setup and install u`r OS fully and u`ll get 1 result. Next time around, wipe the drive, and re-install everything and u`r result will be off by a few %.Quote

No generally that's not the case actually as I have done that a couple of times for varying reasons. You get a score almost exactly identical, shown especially by the benchmarks on these three boards that are exactly the sameQuote

Big question:

Is it better than the IP35 Pro Quote
