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.

Asus USA did block sales of the A8V but some US resellers decided to go it alone with imported european boards.While it does p1$$ me off that there were still boards in europe not upto scratch you have to commend Asus USA for blocking sales and trying to at least look after some customers...they are also honouring RMA's also.
So #1 it does show some resarch was needed before you bought your board as i tried to let everyone know that the first boards available were not PCI lock fixed although any of them do work with the lock and work VERY well.

#1 - Asus never advertised or listed an AGP/PCI lock as a feature on the original release of the A8V Deluxe. That is the only reason we have not yet reviewed this board. While we did have a sample with a working lock, we have stated in every comment about the A8V in memory reviews and articles that Asus had not yet released a production board with this feature, but that they planned to implement this feature in the future.It is also our understanding that the US office even held release of the board to the US market, but many huge on-line vendors direct imported this board or brought it in from European sources. Since we were working with Asus, we know they tried very hard to hold release of this baord until they could work through issues of adding a stable PCI/AGP lock to the A8V.
It is our understanding than Revision 2.0 will implement an AGP/PCI lock, but we have not yet seen the production board, which we expect this week. We will confirm the new feature when the board is received.
We tried to caution readers about the AGP/PCI lock on early VIA boards as loudly as we could. In fact we got a lot of flak from manufacturers and VIA about our articles on the problems with the AGP/PCI lock on early VIA boards.
Asus did not even list the AGP/PCI lock as an option on the AV8 Deluxe. Our suggestion is to contact Asus, but you got the features Asus advertised and listed for this board.

I bought a ASUS A8V like 3 weeks ago, but in the article it says they are re-releasing it or something, does anyone know if they are going to patch that with bios updates, or did I just get the shaft?
