MSI K8N Neo2 Platinum: 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) |
204FSBx13 2652MHz (+10.5%) |
|
| Maximum FSB: (Lower Ratio) |
290FSB x 9 (2610) at 1:1 Memory (+10%) | |
The K8N Neo2 allowed our DDR550 memory to reach the highest 1:1 performance that we have tested on any motherboard - P4 or A64. 290 Frequency (1160 FSB/HT) was the limit of our memory and the K8N reached it rather easily. By reducing the memory ratio a bit, we were right at the board limit of 300, and we could likely reach even higher OC levels with a wider range of frequency choices. The MSI K8N Neo2 was clearly the best overclocker of this roundup.
Memory Stress Test Results:
The memory stress test simply checks the ability of the K8N Neo2 to operate at its officially supported memory frequency (400MHz DDR), at the best performing memory timings that 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 filled.| 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: | N/A |
| RAS to CAS Delay: | 2T |
| RAS Precharge: | 10T* |
| Precharge Delay: | 2T |
| Command Rate: | 1T |
Like the other 939 motherboards in this roundup, the K8N Neo2 was completely stable with 2 DIMMs at the best performing settings of 2-2-2-10 at default speed and 2.6V default voltage. While a full memory comparison of the nVidia and VIA chipsets is beyond the scope of this roundup, we did run several SiSoft Sandra 2004 SP2 runs of the memory test module. At default settings, and the aggressive 2-2-2-10 timings on the FX53, the nF3-250 Ultra showed memory bandwidth in the 6100 range for FPU and Float. The same test on the VIA K8T800 PRO boards showed memory bandwidth in the 6000 range. Performance of both chipsets at the 1T setting was very similar. 2T Command Rates, with everything else the same, generated bandwidths of 4900 to 5000Mb/second.
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: | N/A |
| RAS to CAS Delay: | 2T |
| RAS Precharge: | 10T* |
| Precharge Delay: | 2T |
| Command Rate: | 2T |
The MSI K8N Neo2 was able to run with all 4 DIMM slots at the same aggressive 2-2-2-10 settings used for 2 DIMMs. However, as we have seen on the other 939 boards running all 4 DIMMs, Command Rate must be reduced to 2T when filling both Dual Channels.

#32 Socket 940 boards require ECC memory. 939 don't but they might run it. Go to AMD's website and see.FactorOfTwo - Wednesday, July 21, 2004 - link
Do any Socket 939 boards support ECC memory? I am having a hard time finding a definitive answer to this question.TheLiquidH20 - Wednesday, July 21, 2004 - link
Quote - The general performance of the VIA and nVidia-based 939 boards was virtually the same in DirectX 9 games, with one notable exception. Microsoft's Halo performs almost 15% better on the nVidia nForce3 Ultra .Could this have something to do with Halo being a direct port of the xbox ? Seeing that the Xbox is basically one , big intergrated nForce ? . Would explain microsoft adding some optimazations for niVdia hardware .

Ive got an ABIT AV8 and I wouold like to get a copy of that 1.3 bios you claim you had.rjm55 - Wednesday, July 21, 2004 - link
This is the first time I've seen AnandTech use color in the benchmark graphs. It really makes reading the data a LOT easier. Thanks!Wesley Fink - Tuesday, July 20, 2004 - link
#5 and #26 - I received a retail K8T Neo2 about 10 days ago and the board is now entering retail. I received the retail K8N Neo2 about 4 days ago and I am told it should enter retail in the next week to 10 days. That is the best information I have, but the date has already slipped from early July to the end of July. MSI should have the most reliable information on when the board will finally hit the retail channel.kmmatney - Tuesday, July 20, 2004 - link
Thanks for using the AutoGK encoding benchmark! I prefer the XVid codec, over DivX, but I very much appreciate the benchmark. AutoGK is by far the best freeware encoding suite I've come across.kd4yum - Tuesday, July 20, 2004 - link
See #5ibid
Where is the MSI 939 board?!
Wesley, I asked same question in another Comments section. I can't get answers from MSI (phone) or Newegg (phone). Can you?

#23 - I am now working on a 925X roundup and had switched mental gears. It looks like I need to check my mind set before correcting reviews :-) Now fixed.kd4yum - Tuesday, July 20, 2004 - link
