Asus A8V Deluxe: Overclocking and Stress Testing
FSB Overclocking Results
| Front Side Bus Overclocking Testbed | ||
| Processor: | Athlon 64 FX53 Socket 939 2.4GHz |
|
| CPU Voltage: | 1.5V (default) | |
| Cooling: | Thermaltake Silent Boost K8 | |
| Power Supply: | Antec TruePower 430W | |
| Maximum OC: (Standard Ratios) |
204 x 13 2652MHz (+10.5%) |
|
| Maximum FSB: (Lower Ratio) |
289x9 (2601) at 1:1 Memory | |
The A8V Deluxe Revision 2 has come a long way from the first revision that didn't even have an AGP/PCI lock. Revision 2 is in a virtual dead heat with our top-performing MSI K8N Neo2 at 289 x9 with our Shikatronics DDR550 memory. The A8V also matched the highest OC with this FX53 at 204x13 at default voltage. This overclocking performance is as good as we are accustomed to seeing on the best nForce3 Ultra boards, and can only be called superb when achieved with the VIA K8T800 PRO, which is not always the best overclocker. To achieve this overclock level, we needed to reduce the base Hyper Transport frequency to 800.
Memory Stress Test Results:
The memory stress test measures the ability of the the Asus A8V Deluxe to operate at its officially supported memory frequency (400MHz DDR) at the best performing memory timings our Mushkin PC3500 Level 2 or OCZ PC3500 Platinum Ltd Modules will support. Memory stress testing was conducted by running RAM at 400MHz with 2 DIMM slots operating in Dual-Channel mode. The memory configuration of the Asus is the more standard setup with slots 1 and 3 are the first Dual Channel.| Stable DDR400 Timings - 2 DIMMs (2/4 DIMMs - 1 Dual-Channel Bank) |
|
| Clock Speed: | 200MHz |
| Timing Mode: | N/A |
| CAS Latency: | 2.0 |
| Bank Interleave: | Enabled |
| RAS to CAS Delay: | 3T |
| RAS Precharge: | 10T* |
| Precharge Delay: | 2T |
| Command Rate: | 1T |
The Asus K8V Deluxe Rev.2 was completely stable with 2 dimms in Dual-Channel at the settings of 2-2-3-10 at 2.6V default voltage with 1T command rate. This is very slightly slower than the timings than worked on other Socket 939 boards. While we could run the majority of benchmarks at 2-2-2 timings, there were a few that were not completely stable until we increased Ras-to-Cas delay to 3. It should be noted that the BH5 memory modules we used for testing are no longer available for purchase, but we have not yet established our standard memory for future testing. We will be using a new standard memory in future motherboard tests.
As we first found in our latest Socket 754 roundup, the Command Rate is very important for top performance on a VIA chipset motherboard. The best performance is at a Command Rate of 1T, and the Asus A8V was completely stable at a 1T setting with 2 dimms. We set 'Bank Interleave' to 'Enabled' in the BIOS, and Sandra 2004 SP2 reported a 2-way Bank Interleave was being used by the memory controller. With an on-CPU memory controller with Athlon 64, this is not as important a setting as it is on with chipset-based memory controllers.
Filling all four available memory slots is more strenuous on the memory subsystem than testing 2 DIMMs on a motherboard.
| Stable DDR400 Timings - 4 DIMMs (4/4 DIMMs - 2 Dual-Channel Banks) |
|
| Clock Speed: | 200MHz |
| Timing Mode: | N/A |
| CAS Latency: | 2.0 |
| Bank Interleave: | Enabled |
| RAS to CAS Delay: | 2T |
| RAS Precharge: | 10T* |
| Precharge Delay: | 2T |
| Command Rate: | 2T |
We see a very interesting result with all 4 dimm banks filled. The Asus A8V was able to run with all 4 dimm slots at more aggressive 2-2-2-10 settings than the 2-2-3-10 required for 2 dimms. Please keep in mind, though, that the Command Rate must be reduced to 2T when filling both Dual Channels, and the memory is actually a bit slower even though the other timings are slightly faster. The A8V Deluxe is also very picky about the settings that are used with 4 dimms in the 'Enable 2T' option in BIOS. If an Auto setting is used with 4 dimms the board tries to set 1T and single channel memory at a lower memory speed. If 'Auto' is selected and memory timings are forced to DDR400 the board would not boot. With 4 dimms, you will need to set the 2T option to 'Enable 2T' for proper Dual-Channel operation at DDR400.

I am using the Gigabyte 939 NF3 board for the past week now. It appears that their are two lan connections listed as Marvell (lan 1) and Nvidia (lan 2). I have been using the Nvidia one?To get the firewall to function with the Gigabyte board all you have to do is download the Nvidia 4 in 1's after installing the Gigabyte drivers.
Of course I'm a noob.

#70 - The nVidia fiewall is a port on the chipset that allows for direct communication with the Gigabit chip PHY layer. It is therefore very difficult to determine if the on-chip port is being used just from looking at the specifications.Earlier this week we asked nVidia for help in identifying which motherboards were using the on-chip gigabit port. nVidia is looking into the list of boards we supplied and said they would be providing us with updated information soon. When we receive that info we will post it.

Any chance to have tested the OCZ 4000 gold rev 2, with the 2.5-3-3 latencies and compare that to the 3700 EB?Curious as I narrow down things.
Any news on Pci-e for AMD64's?
Thanks!

i too would like to know whether the Gigabyte NF3 board uses the nVidia NIC/firewall, and if not not, why anandtech failed to mention the fact?geogecko - Thursday, July 29, 2004 - link
What is the noise difference in the retail packaged CPU fans in this class (S-939), and the Thermaltake Silent Boost K8 used in the reviews.I notice that Thermaltake also has another CPU cooler using heatpipes, the SilentTower 4-in-1 CPU Cooler. Have you guys tested this out?
My current PC (AMD XP 1800+ with the equivalent of a Volcano 9) gets too loud for me when it gets warmed up, and that's with it sitting on the floor next to my desk.

#62, you must have read the post incorrectly. I was hoping you would have used the same CPU, which you did not. Somehow you read the opposite. I figure in comparing the chipset to the other, using a different CPU throws in a ton of extra variables. Now if you are looking at it from a prospective of which is faster, then your setup is fair. Of course most people would buy the Northwood on the 875 but it becomes more of a platform benchmark rather than anything that could be called a chipset competition.About the FX53, one reason I do not like you using it is because it is AMD's flagship product and at least from what I remember, the Presscott that you used was not an EE. Even so, the biggest bother is that the FX53 will always cost more than $500 and very few people will actually ever buy it when they can get so much more band for their month with just a regular class AMD64. This is the case with the EE too, they will always cost an arm and a leg so I'd say only about 5% of people will be buying the FX and the EE series chips. By an overwhelming majority, most consumers will be buying the non-enthusiast parts.

Please take this as the official responce to the rumours about 3500 and 3700EB.We have NOT stopped production of these modules, it sells quicker than we can produce it..that is the only real issue.
We have just shipped another huge order so please go bug your favourite stores to stock it..
EB is here to stay at least for the time being.

Also, has the performance discrepancy with Halo and the nforce boards ben figured out yet? If it somehting that may resurface in other games ill get an nforce board. If it is fixable or just a one off with halo, i can save a few $ and get a via board while i am waiting for PCIx...John

Does the Gigabyte board use the Nvidia LAN as well? I see it says marvel but after the last series of posts with the marvell/nvidia chipset i am confused now...Anemone - Monday, July 26, 2004 - link
Thank you for enlightening on the LAN issue with the NF3 ultra - for me I'm getting and FX.Since this article is getting referenced a lot with people I talk with and such, can we keep a front page link to it for a while?
Also looking forward to memory reviews as well. Rather sad the 3700EB has been discontinued :(
Hopefully OCZ will have something better to take its place in not too long, but that might be impossible.
