ASUS Striker II Extreme: Mucho Bang, Mucho Bucks

Memory Access Latency and Read Performance
Each of the DDR3-based motherboard showed about a 10% reduction in random memory access latency figures. As expected, the board with the Intel X48 Express chipset, the ASUS P5E3 Premium, takes the gold in this event.
400MHz FSB showed additional small improvements with even lower memory access latencies. Unlike the boards with an NVIDIA chipset, the ASUS P5E3 Premium showed another nice drop in latency simply by moving to the higher multiplier (overclocking our QX9770 from 3.20GHz to 4.00GHz). As previously noted, these low access times are precisely the reason why UT3 runs so well on our X48 board.
We saw the best memory access latencies of the day with our X48-based P5E3 Premium at 500FSB. The real surprise however came from the EVGA NVIDIA nForce 780i SLI, which showed DDR2 could be nearly as effective at producing low access times as DDR3 when properly tuned.
NVIDIA really surprised us with the quality of their first DDR3 memory controller; besting Intel's X48 design was the last thing we expected to see from 790i. According to these results, even DDR3 value memory outperforms the midrange DDR2 modules flooding the market.
Both EVGA's and ASUS' 790i boards absolutely demolished the P5E3 Premium when it came to raw memory read bandwidth - 500MB/s is a big lead to hold when comparing memory controller performance with memory running at equivalent speeds. The extra 10% memory read throughput seen with DDR3-1600 over DDR2-1066 shows up well in some of the gaming benchmarks. This goes a long way towards dispelling the early, unsubstantiated rumors of lackluster performance from DDR3 memory.
The 790i pulls even farther ahead when the FSB is increased to 500MHz. Intel's X48 Express chipset begins to run out of steam at around 465-475MHz FSB. The same would be true for NVIDIA's 790i Ultra if it were not for the cryptic "P1" and "P2" BIOS options.

Can anyone here indicate how to reach FSB 500 (2000) with Striker II Extreme & QX9770 C1, most I can get is 1900FSB.I've seen Kris reach this speed in this article & was eager to get to this speed as soon as I received my new CPU, but it has been more difficult than I thought, I was sure that if with my previous Q6600 G0 y could easily get 1900/1950FSB, now with QX9770 would be peanuts. The main reason I bought this CPU was to run 2000FSB linked & synced with Ballistix 2000 SLI.
Please give all detailed BIOS setup options for this CPU if possible
Nobody in Asus forum using this setup has been able to reach 2000FSB, but I have seen a few reviews (like Anandtech's) & posts showing it's possible
By the way, memory has been tested unlinked at 2000Mhz 9-8-8-24, 1.9v P1/P2 Enabled & works great
System:
QX9770 rev. C1 3.2Ghz (watercooled)
Asus Striker II Extreme BIOS 801, ver 1.02G (watercooled)
PC Power & Cooling Turbo Cool 1200W
4 x 1GB Crucial Ballistix PC16000 SLI EPP2 , 2000Mhz 1800 8-7-7-24- 1T - 1.9v
SLI Leadtek PX8800 Ultra Leviathan (factory watercooled)
SLI Leadtek PX8800 Ultra
Asus Physx card (removed)
Dlink DWA556 PCIx Xtreme N Wireless card
2x WD Raptor 150GB Raid 0 300GB

I used the same motherboard and cpu, but I liquid cooled it using the gigantic Kandalf Liquid Cooled case. My memory is different as well since I use 4 GB of Patriot Viper memory (2 x 2GB). Other than the memory settings in the BIOS, I set everything to match this guide. My system runs at 4.0Ghz and the cpu runs at no more than 88 degrees fahrenheit even while playing something like Crysis with everything set to Very High. Crysis runs between 35 and 60 fps on Very High on my system using a single 9800 GX2 at 1280 x 720. It's a HTPC connected to my older 56 inch DLP set via DVI, so I can't go any higher than that, but I fully expect to run great at 1080p when I get my new large screen set later this year. I don't have my bios settings in front of me, but setting everything to Auto for the memory works PERECTLY at 4.0 ghz. Pretty cool. I think it's running at 8,8,18 or so and 1.9v.Also, Asus just released a patch to the bios that fixes the data corruption issue mentioned in this artcle. Released on 5/29/08 I think.

The water block seems to have leaking issues , I am wondering why it was not covered in this review since it is a major feature of this board ......Heatlesssun - Sunday, April 20, 2008 - link
This is a sweet motherbaord! Now I've not overclocked the FSB, just bumped up the multiplier of my QX9650 from the default of 9.5 to 10, and I'm not running RAID. We shall see but I feel good. To get this up and running with Vista x64 in a day so smoothly was pretty good I thought.electricx - Tuesday, April 15, 2008 - link
So this board is going for the aforementioned amount on newegg... The EVGA and the XFX 790i boards are going for $350... The ROG name carries that much of a premium? I mean, come on?! I'm sure ASUS will fix this data corruption issue and you typically do pay more for the privilege(?) of being a beta tester for high end hardware but $1000 over competing products seems a bit much... The EVGA board is looking to be a clear winner here to me. Time will tell I suppose.FightingEagle - Friday, April 18, 2008 - link
After the second EVGA 790i and full of bugs I just sent it back. I was interested in the ASUS X48 and the 790i, but the 790i over $400 is hard to grasp. EVGA has good looking heat sink but not very good at cooling. I may wait for all the bugs to leave but as now im sitting on $320 dollars worth of DDR3 and a E8400.electricx - Tuesday, April 15, 2008 - link
Edit: That should have been $100 not $1000UK1Man - Sunday, April 13, 2008 - link
Help please!!I'm currently in the process of building a computer but can only afford to buy a couple of parts a month, I have already purchased some DDR2 (1066) memory for an FXF 780 motherboard (not yet purchased) but am now considering the Asus striker II extreme.
Will my DDR 2 memory work with this?

This board/chipset, 790i, only supports DDR3.ianken - Saturday, April 12, 2008 - link
Can it go into S3 suspend and come back out and have the NICs still work? The Striker 2 Formula cannot.Can the SATA controller handle hot swap? The Stiker 2 Formula and the previous 680i boards could not. The 680i bios even had an esata setting that did NOTHING.
The latest crop of Asus boards, particularly the NV chipset rigs, have been pretty buggy and basic functionality has been borked.
But hey, who cares of the basics don't work right? it's got a water block for X-TREME OVERCLOXORS! YO! VTEC!
