MSI K8T Neo2-FIR: 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) |
200FSB x12 2600MHz (+10%) |
|
| Maximum FSB: (Lower Ratio) |
263FSB x 9 at 1:1 Memory | |
While the K8T Neo2 reached the next performance level of 2.6GHz at a 13 multiplier, it was not the CPU frequency overclocker that we see in the nVidia-based K8N Neo2. No matter the multiplier, the top frequency that we could reach with stability was 263, much lower than the 290 on the K8N Neo2, or the 280 reached on the Abit AV8.
Memory Stress Test Results:
The memory stress test is very basic, and simply tests the ability of the K8T 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 in a Dual-Channel configuration with a Command Rate setting of 1T.| 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 (10T for Best Performance)* |
| Precharge Delay: | 2T |
| Command Rate: | 1T |
The K8T Neo2 had no problem at all with 2 dimms at aggressive 2-2-2-10 timings and a 1T Command Rate. We were frankly surprised at how well all the boards handled our BH5 memory, since it has sometimes been a problem memory on Athlon 64 boards. We do have to wonder if this is really the memory, however, or just the truly excellent memory controller on our replacement FX53.
Filling all four available memory slots is more strenuous on the memory subsystem than testing 2 DIMMs on a motherboard. We really expected to have to make concessions to memory timing with 4 DIMMs on all the 939 motherboards, but in fact, every board in the roundup had no problem with 2-2-2-10 timings at 1T.
| 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 K8T Neo2 was able to run with all 4 DIMM slots at the same aggressive 2-2-2-10 settings used for 2 DIMMs. As we have seen on the other 939 boards running all 4 DIMMs, the Command Rate must be reduced to 2T when filling both Dual Channels.

Also, networking benches would have been nice (throughput and CPU utilization). It would be interesting to see what kind of impact Gigabyte going with a 3rd party ethernet controller has in comparison to the MSI board using the NF3's controller.On a somewhat related note, when will the Neo2 actually be available for purchase?

How about telling board makers to use better Sound for their boards.I got my board as it came with a VIA Envy soundcard. When I see RealTek sound that tells me they don;t care about quality, but about what they can say comes with the board.
Even C-Media has a new full (non-ac97) soundchip out now that can;t be that much more then a realtek 850/650/655 chip.

#7,8,9 - Corrected. Since ECS did use a SiS chip on their VIA board for secondary RAID, I got confused and spread the chipsets around :-)Stefpet - Tuesday, July 20, 2004 - link
...but when will we see K8T890 or nforce4 motherboards?I don't want to be forced to replace the motherboard with a new one to get that top performing PCI Express card later...

Final words, somewhere in the middle of the page:"The ECS is a remarkable step forward for ECS"
:c)
Great work, though.

Silly me, I meant ECS, not Epox.RyanVM - Tuesday, July 20, 2004 - link
"8 USB 2.0 ports supported by nF3-250" for the K8T800PRO-based Epox KV2?Wesley Fink - Tuesday, July 20, 2004 - link
#4 - Corrected. With more than 9000 words a number typo seems inevitable.BLHealthy4life - Tuesday, July 20, 2004 - link
Still can't find the MSI K8n Neo2 mobo for sale anywhere.Been waiting and waiting....and waiting some more...

Our FX53 topped out at about 2.59 GHz on the ECS KV2, which is slightly below the 3.6+ achieved on the top 939 boards
