Asus P4S800D-E: Stress Testing
We performed stress tests on the P4S800D-E in these areas and configurations:1. Chipset and motherboard stress testing, conducted by running the FSB at 264MHz with synchronous (1:1) memory speed (DDR528) with OCZ 4200 EL memory.
2. Memory stress testing, conducted by running RAM at 400MHz with 2 Dual-Channel (1 bank) DIMM slots filled and at 400MHz with all 4 Dual-Channel (2 bank) DIMM slots filled at the lowest memory timings possible with Mushkin PC3500 Level II memory.
Front Side Bus Stress Test Results:
We ran a full range of stress tests and benchmarks to ensure that the Asus P4S800D-E was absolutely stable at each of the overclocked FSB speeds. This included Prime95 torture tests, and the addition of other tasks — data compression, various DX8 and DX9 games, and apps like Word and Excel — while Prime95 was running in the background. At default voltage, 267MHz was the highest overclock that we were able to achieve with an asynchronous memory setting; 264 was the highest overclock that we could achieve with a synchronous memory setting.Memory Stress Test Results:
This memory stress test is very basic, as it simply tests the ability of the P4S800D-E to operate at its officially supported memory frequency (400MHz DDR) at the lowest supported memory timings that our Mushkin High Performance ECC Registered Modules will support:| Stable DDR400 Timings — 2 DIMMs 2/4 DIMMs populated — 1 DC bank |
|
| Clock Speed: | 200MHz |
| Timing Mode: | 128-bit DC |
| CAS Latency: | 2.0 |
| Bank Interleave: | N/A |
| RAS to CAS Delay: | 2T |
| RAS Precharge: | 6T |
| Precharge Delay: | 2T |
| Command Rate: | Auto |
We had no problem running 2 DS 512MB DIMMs of our standard Mushkin PC3500 Level2 and OCZ 3500 Platinum Ltd in the P4S800D-E at the most aggressive timings. To achieve complete stability at 2-2-2-6 timings, we did have to slightly increase vDIMM voltage to 2.65V.
Filling all available memory banks is more strenuous on the memory subsystem than testing 2 DIMMs, but we had no problem at all running with all 4 DIMMs filled providing 2 Dual-Channel Banks.
| Stable DDR400 Timings — 4 DIMMs 4/4 DIMMs populated — 2 DC bank |
|
| Clock Speed: | 200MHz |
| Timing Mode: | 128-bit DC |
| CAS Latency: | 2.0 |
| Bank Interleave: | N/A |
| RAS to CAS Delay: | 2T |
| RAS Precharge: | 6T |
| Precharge Delay: | 2T |
| Command Rate: | Auto |
The required memory timings with 4 DIMMs were the same as 2 DIMMs, the fastest 2-2-2-6 timings our memory could achieve. For maximum stability, we had to increase vDIMM to 2.65V, the same as our 2 DIMM setup. The P4S800D-E was completely stable at these timings and voltage.
As a side note, at default 2.5 vDIMM, the fastest stable memory timings with both 2 and 4 DIMMs were 2-2-3-6. While most tests were fine at 2-2-2-6, long-term stress testing eventually caused memory failures unless the settings were slowed to 2-2-3-6 or memory voltage was increased to 2.65V. Prime95 torture tests were successfully run at the timings listed in the above charts. We also ran Sciencemark (memory tests only) and Super Pi. None of the three stress tests created any stability problems for the Asus P4S800D-E at these memory timings and 2.65V.

Q? to Wesley does these mobos have control of CPU fan speed (again like MSI Neo2), so it run more slow with low CPU load (= more silent)?Another one is how it's compatible with Radeon 9700 Pro? F.e. My SIS648 even with latest SIS-AGP drivers have have a conflict with Hercules R9700Pro when Fast Write is turned on...
Competition is G R E A T E thing,... but you know we also want stability :))) So far, as I know Intel chipsets before were far more stable and compatible with other hardware...
The bottom line "as fast" does not always mean "as good"... :(( And since I also love competition let's hope that SIS655TX as good as 875P.

A good article on a serie of good boards, I'm very happy you took the P4C800-E dlx in the test.I'm more then happy with the increased competition these boards bring, the P4C800-e dlx is still about 199 in euro land.

When is the Asus P4S800D-E coming out? Nada on pricewatchWesley Fink - Wednesday, December 10, 2003 - link
Several of the cells in the Feature Table on page 3 were reversed and have now been corrected.Dual Channel (2x64 bit) is called 128 bit mode on the SiS. The BIOS has the option to run 128-bit (Dual-Channel) mode or to force Dual 64-bit.

Also, as I remember VIA VT6307 support 3 (not 2) 1394a FireWire ports (as on MSI Neo boards), so why Gigabyte would cut them to 2 ???And besides Wesley always trying to stress out color-coded panel connectors.
For me it's more important that you can change RAM without taking off videocard and ASUS had such problems with some of their mobos (now it looks better... but talking about overclocking ... hmmmm.
Even it's damn stable: heatsink on ASUS SiS 655TX is passive (already -) and too close to CPU (plus wrong orientation - same mistake as with original
P4C800 Deluxe. So - NO oversized cooler for CPU on this board.

Realtek ALC658 codec AC '97 2.36-Channel with UAJ Shoud go to Gigabyte and vice versa...
Oh well.., I had my SIS648 for a while and .. so now I'd rather prefer to pay eXtra for board with Intel chipset :((
Plus Gigabit LAN will work faster(=better) with CSA...

Hey guys... In the features table on-board audio codecs are mixed up :)Shalmanese - Tuesday, December 9, 2003 - link
Er, I don't think Sis supports 33Mhz Memory speeds... (pg 5) ;).What happened to the tech support turnaround time bit? That was always the favourite part of your reviews.

On page 3 it says its the Gigabyte MB that uses the Marvel Gigabit controller, while on page 4 it says its the asus board that uses the Marvel controller... My guess is it is Asus that uses it and its wrong on page 3.FishTankX - Tuesday, December 9, 2003 - link
What on earth is the difference?There is no commercially avaliable 128 bit DDRSDRAM. All DDRSDRAM is 64 bit.
