ASUS Striker II Extreme: Mucho Bang, Mucho Bucks

Intel 45nm Quad-Core Overclocking
Perhaps the greatest ability the ASUS Striker II Extreme has to offer is its amazing performance when overclocking 45nm dual-cores, 45nm quad-cores, and high-speed DDR3 memory. We have tested numerous motherboards built on many different platforms with several different chipsets but none has performed as well as the ASUS Striker II Extreme when it comes to overclocking our Intel QX9770. A little time spent with tweaking the GTL reference voltages and we found ourselves starting at a Prime95 stable system running a 45nm quad-core at 500MHz FSB.
 A 45nm quad-core at 500MHz FSB? Doth my eyes deceive me? |
We then turned our sights to memory overclocking and decided to see just how far we could push 8GB of OCZ DDR PC3-14400 Platinum Edition memory. One of the secrets to running high physical memory densities - whether DDR2 or DDR3 - is tRFC, an important memory timing parameter, necessary for the proper refresh of SDRAM circuitry. Although JEDEC provides different tRFC minimum value specifications for each device density, most overclockers ignore these values when it comes to achieving maximum system performance.
 While DDR3-2000 memory speeds may no longer be impressive to some, we tend to believe seeing this with 8GB of DDR3 is quite an accomplishment for today's boards. |
Because of the design of memory, SDRAM must be periodically refreshed in order to retain the validity of data stored in each memory cell. All banks of the SDRAM must be precharged and idle for a minimum of the Precharge Time (tRP) before this refresh command can be applied. Once the refresh cycle has completed all banks of the SDRAM will then be in the precharged (idle) state and a delay between the Refresh Command and the next Active Command or subsequent Refresh Command must be greater than or equal to the Refresh Cycle Time (tRFC).
Higher memory device densities with a greater number of SDRAM banks require more cycles to complete this refresh sequence. The number of clock cycles needed to satisfy the tRFC minimum specification for a system configuration consisting of a pair of 2GB modules, although not double that of 1GB modules, is still significantly higher - about 53% higher according to JEDEC figures - and installing four separate modules in place of two makes consideration of this timing even more critical.
 This is just the level of performance we have come to expect from DDR3. The fact that we can achieve this with 8GB though is simply awesome. |
Our greatest memory performance point actually came at DDR3-1600 (500MHz FSB and a 5:4 divider) with 8GB of memory. We could not get the system to run without errors with 8GB at DDR3-2000 with "P1" and "P2" enabled (we will talk more about these particular settings later in the BIOS guide). Backing down to DDR3-1600 and enabling these values boosted our memory read scores to almost 12GB/s.

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
1x Seagate 400GB Sata
X-Fi Platinum Fatal1ty Champion
24' Benq FP241VW Gamer
Innovatek XXD Rev 2 + G-Flow water cooling
CoolerMaster Cosmos 1000 case
Saitek X52 Flight system
TrackIR 4 + Trackclip Pro
Windows Vista Home Premium 32bit

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?
seamusmc - Monday, April 14, 2008 - link
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!
