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.

If you are looking for the K8NN939 beta M03 again its availabale at bleedinedge.com on bigtoe's bios bin.http://www.bleedinedge.com/forum/showpost.php?p=32...

The msi K8N Neo2 will hit the states in 2 weeks according to MSI.How will the A8V rev. 2.0 be sold in terms of order by model #. Same or different? Rev. # is only printed on the PCB, not the box.

I love my new Gigabyte 939 board! It kicks a*s and is perrrty in the dark! :)Wesley Fink - Wednesday, July 21, 2004 - link
#36 - The new Gigabyte BIOS DOES have multipliers in BIOS as I detailed in the review specifications. See the link in #35.RyanVM - Wednesday, July 21, 2004 - link
With performance getting so similar between the various boards/chipsets, it seems to me that AT is overlooking some of the bigger differentiating factors: integrated features. It would be nice to see how the USB, Firewire, IDE/SATA, Ethernet, Sound, etc. implementations differ in CPU utilization and overall performance.For example, the Gigabyte (inexplicably) uses a 3rd party GigE controller instead of the NF3-250's controller. What impact on throughput/CPU utilization does this have? How is VIA's SATA implementation compared to nVidia's?
It seems to me that those are become more relevant of questions than "Which board has a higher Winstone rating?"

I had heard the Gigabyte board would not let you adjust the multipler in the bios but I saw a picture where it could be adjusted from the software in windows? Is this true? Any disadvantages to this? Also just how bad is the voltage limit holding the Gigabyte board back? Is there anyway Gigabyte could allow you any more voltage adjusts through the bios in the future or is this board hopeless for volts?bigtoe33 - Wednesday, July 21, 2004 - link
For all who want the AV8 bios...first join the forums over at www.bleedinedge.com, then look in bigtoe's bios bin. you will find the bios under abit amd boards.http://www.bleedinedge.com/forum/showpost.php?p=32...

#31 - A friend will post a host for the BIOS soon, as I can't handle all the individual requests. Until then email me and I will be happy to send it to you.#32 & #33 - The Socket 939 boards WILL handle ECC and non-ECC memory, but I suspect the question is larger than this. Socket 940/Opteron requires REGISTERED memory and the ECC can be on or off. We have tested the 939 with Registered memory and it is definitely NOT compatable with Registered memory. If you want to keep using Registered memory (Which you may have bought for 940) you will have to stick with an Opteron.
