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.

Hi, this is a great article. I'm really disappointed that the issues with the new Winchesters and the MSI board were not uncovered. The new CPUs will not post past FSB of 219, which is far below the 250 many get with other boards. Someone with the depth of knowledge, experience, and understanding of all these little options in the BIOS could help us uncover the real problem. Here's the best thread devoted specifically to the problem on Rebel HQ:http://www.rhcf.com/sisubb/ultimatebb.php/topic/21...

Hey,I enjoyed the round up of the SLI boards very much and thought it was very thorough.
I own an A8N SLI Deluxe board, and too have been thoroughly disappointed with it's overclocking performance.
On behalf of tens of users on the Anandtech - Motherboards forums, would it be beyond Anandtech's power to get a statement from Asus about the issue???
At a 2T Command Rate the board will overclock to 316, 1T however just 249. The sudden BSODing as you approach 250 smacks of something that could be fixed with a BIOS update.
Please Anandtech, A8N users are begging for this to be fixed, or at least be told it can't be.
Many thanks, and again, a great article.

is it true that the MSI board doesnt have a PCI Express x1 slot so that when the new Creative PCI express sound cards come out it wont fit?Viper4185 - Monday, February 28, 2005 - link
Thanks for the review guys, just what I wanted! Although I am interested in the Ultra versions its still very similar...I was wondring if you could comment on the stability/stress testing of the DFI board as Hardocp seems to have had some issues...

Also would have been good if you included the Abit Fatal1ty board to make the review 100% conclusive for me.

dang, I wasn't first, oh well.one more thing....I no longer chase the FPS demon, and I am better for it (mentally and emotionally). To be honest I don't expect SLI to become a standard in MB design.....even for high end gamers. Isn't the price just too high?
nzimmers - Monday, February 28, 2005 - link
First post!I was actually really (plesantly) surprised that DFI did so well. I know that they have been improving lately but isn't it great to see another MB manufacturer improving for once?

finally...., thx 4 your reviewjkv71 - Saturday, June 3, 2017 - link
My DFI video quit. I use an adapter to run hdmi on my tv. I replaced the video card and still nothing. I replaced the mother board. Still nothing. Any ideas?
