nForce4 SLI Roundup: Painful and Rewarding

Asus A8N-SLI Deluxe: Overclocking and Stress Testing
| Front Side Bus Overclocking Testbed | |
| Asus A8N-SLI Deluxe | |
| Processor: | Athlon 64 4000+ (2.4GHz, 1MB Cache) |
| CPU Voltage: | 1.5375V (default 1.50V) |
| Cooling: | Thermaltake Silent Boost K8 Heat sink/Fan |
| Power Supply: | OCZ Power Stream 520W |
| Memory: | OCZ PC3200 EL Platinum Rev. 2 (Samsung TCCD Memory Chips) |
| Hard Drive: | Seagate 120GB 7200RPM SATA 8MB Cache |
| Maximum OC: (Standard Ratio) |
234x12 (Auto HT, 2-3-3-7, 1T, 2.8V) 2808MHz (+17%) |
| Maximum FSB: (Lower Ratio) |
255x11 (2805MHz) (4X HT, 2.5-3-3-7, 2.7V) (1:1 Memory, 1T, 2 DIMMs in DC mode) (+28% Bus Overclock) |
Asus has been the overclocking leader in many of our recent Intel processor roundups, so it was certainly a disappointment that the Asus turned out to be a below-average overclocker in the SLI roundup. The highest CPU speed that we could reach with stability was 255, but performance at the stock 12 multiplier of our 4000+ was a respectable 234. With two of the boards in the SLI roundup going well above 300 in the same configuration, this was hardly impressive overclocking.
Memory Stress Test Results:
Memory stress tests look at the ability of the Asus A8N-SLI to operate at the officially supported memory frequency at the best performing memory timings that our standard OCZ PC3200 Platinum Rev. 2 will support. Memory stress testing was conducted by running 1:1 at DDR400 with 2 DIMM slots operating in Dual-Channel mode.| Stable DDR400 Timings - One Dual-Channel (2/4 DIMMs populated) |
|
| Clock Speed: | 200MHz |
| CAS Latency: | 2.0 |
| RAS to CAS Delay: | 2T |
| RAS Precharge: | 7T |
| Precharge Delay: | 2T |
| Command Rate: | 1T |
The Asus SLI was completely stable with 2 DDR modules in Dual-Channel at the settings of 2-2-2-7 at default voltage. This matches the best timings that all of the SLI motherboards in this roundup were able to achieve.
Filling all four available memory slots is more strenuous on the memory subsystem than testing 2 DDR modules on a motherboard.
| Stable DDR400 Timings - 4 DIMMs (4/4 DIMMs populated) |
|
| Clock Speed: | 200MHz |
| CAS Latency: | 2.0 |
| RAS to CAS Delay: | 2T |
| RAS Precharge: | 7T |
| Precharge Delay: | 2T |
| Command Rate: | 2T |
The Asus K8N-SLI was completely stable at 2-2-2-7 memory timings. We did have to lower the Command Rate to 2T, but this is a function of the on-chip Athlon 64 memory controller. It is rumored that upcoming Rev. E chips will have an updated memory controller capable of driving 4 DIMMs at 1T command rate, which would definitely improve memory performance when running 4 DIMMs.

Wesley did you spend any time at all on this link, I consider this to be a serious issue

When I set up my MSI board I cannot get surround sound out of the optical digital cable except for DVDs. I verified this on a few web sites. Not why there is conflicting information but mine is real world experience with current drivers (did not use packaged CDs)

#28, 31 and 32...The onboard Creative Sound Blaster Live! 24-bit samples at 192 KHz instead of 96 KHz (like Realtek's ALC880/880D and 850) and features full support for Creative's EAX HD technology. Additionally, the soundcard has also passed Dolby certification for Dolby Digital and Dolby Digital EX and has an integrated Dolby interactive content encoder!

#41 I've got a TT WS0049 PS, so I should be good with the -5v.#43 I've already cancled my DFI SLI DR board. MSI here I come ($238 cdn... so it's cheaper too) :D

#42 - The on-board nF4 LAN requires a PHY (Physical Layer) gigabit LAN to function properly, but is specified as PCIe. All 4 SLI boards implement PCI Express Gigabit LAN with the PHY chips (Vitesse or Marvel). If you check all 4 manuals you will see Gigabit PCIe LAN specified by all 4 for the on-chip LAN.#40 - From the MSI manual Audio specifications:
"Dolby Digital Encoder. 24-bit/96-192kHz audio quality. Up to 100db SNR. 7.1 channel H/W audio."

Wesley,"all 4 SLI boards implement PCIe on Gigabit #1"
I don't think the onboard LAN on the nForce4 chipset uses the PCI-E bus, are you sure about this?

Here's the address for a MSI forum note concerning the problem with the Creative onboard sound and power supplies without a -5 volt connection.http://diamondclub.msi.com.tw/eng/forum/viewthread...
And, if you take a look at the ATX12V Power Supply Design Guide, you can see that the lack of a -5 volt connection on many current power supplies should not have come as a surprise to MSI.

WOW! This is looking good...Manual available here:
http://www.msi.com.tw/program/support/manual/mnu/s...
Page 5-1 of the MS 7100 manual (At MSI)
CA0106
Brand new Azalia Spec
8 Channel & SPDIF audio effect
Page 5-8
After installing teh creative audio driver, you are able to use teh 2-,4-,6- or 8- channel and the SPDIF audio featre now..
Page 5-11
Decoder shows SPDIF Passthrough option!!!
I am not familiar with the old Creative Live 24 hardware or menu settings, but is this new?

BTW: If this is the case, I am canceling my DFI preorder (I've been waiting almost 1 month for this board to become available....)Good things may indeed come to those who wait! There is no better way to hook up to my Z5500's if the encode is supported!

#28, #31, I'd really like to know as well...#32, I guess this is brought up, because of this statement in the roundup (on the first MSI Page)
"The Audio also fully supports Dolby Digital encoding, which will matter a great deal to some users."
Anand, is this some sort of typo, or can the onboard solution in facte ENCODE dolby digital audio. The ENCODE assumes that it can take .wav audio and encode it to dolby digital and place it on any (analog/SPDIF Coax/Toslink) output (ala IntelHD and SoundStorm)
Let us know :D
