Albatron PX915P Pro: Overclocking and Stress Testing
| Front Side Bus Overclocking Testbed | |
| Processor: | Pentium 4 Prescott LGA 775 560 ES (2.8GHz-3.6GHz) |
| CPU Voltage: | 1.425V (1.3675V default) |
| Cooling: | Thermaltake Jungle 502 |
| Power Supply: | OCZ Power Stream 520 |
| Maximum CPU OverClock: | 222x18 (3996MHz) +11% |
| Maximum FSB OC: | 250FSB x 14 (+25%) |
The Albatron 915P Pro was an above-average performer in our overclock tests, reaching 3996MHz at the stock 18X multiplier. At the Speedstep 14X ratio, the Albatron performed fine to a 250 FSB setting. Above 250, the SATA drive disappeared and it was not possible to boot at higher FSB settings. Since the Albatron continued to boot to the hard drive initialization stage at higher FSB, the Albatron may reach higher overclocks with an IDE drive.
A few weeks after the launch of the Intel 915/925X chipsets, Albatron made some claims that the key to high overclocks on the 915 chipset was increasing Northbridge voltage. We did not find that further increases in NB voltage allowed any higher overclock with SATA drives - 250 was the limit for our components on the Albatron.

Memory Stress Test Results:
The memory stress test measures the ability of the Albatron PX915P Pro to operate at its officially supported memory frequency (400MHz DDR), at the best performing memory timings that OCZ PC4200 Platinum Rev. 2 will support. Memory stress testing was conducted by running DDR at 400MHz (stock 1:1 ratio) with 2 DIMM slots operating in Dual-Channel mode.| Stable DDR400 Timings - 2 DIMMs (2/4 DIMMs - 1 Dual-Channel Bank) |
|
| Clock Speed: | 200MHz |
| Timing Mode: | 1:1 (200:200 - Default) |
| CAS Latency: | 2.0 |
| Bank Interleave: | Auto |
| RAS to CAS Delay: | 2 |
| RAS Precharge: | 2 |
| Cycle Time (tRAS): | 5 |
The Albatron was completely stable with 2 DIMMs in Dual-Channel at DDR400 settings of 2-2-2-5 at 2.6V default voltage. These are the fastest settings available with the DDR400 test DIMMs.
Filling all four available memory slots is more strenuous on the memory subsystem than testing 2 DDR2 modules on a motherboard.
| Stable DDR400 Timings - 4 DIMMs (4/4 DIMMs - 2 Dual-Channel Banks) |
|
| Clock Speed: | 200MHz |
| Timing Mode: | 1:1 (200:200 - Default) |
| CAS Latency: | 2.0 |
| Bank Interleave: | Auto |
| RAS to CAS Delay: | 2 |
| RAS Precharge: | 2 |
| Cycle Time (tRAS): | 5 |
The system was stable with 4 DIMMs at the same aggressive settings used for 2 DIMMs.

Of course the Pentium 4 560 is gonna be outperformed, The Pentium 4 560 is designed to compete at the 417US price point while the Athlon FX 55 is designed for the 827US, were talking double the P4 560 in price. i believethe closest competitor for the Pentium 4 560 in price is probably the Athlon 64 3700+ even though it is on Single Channel DDR.danidentity - Tuesday, December 7, 2004 - link
Even the 3800+ could be included, but that is still about $180 more expensive than the 560, according to Newegg.danidentity - Tuesday, December 7, 2004 - link
I know comments like I'm about to make have been made before, and I am not biased, but I wanted to reiterate.Why is the FX-55 even part of the benchmarks in this review? Why not a 3500+? The FX-55 is TWICE the price of the Pentium 560 according to current Newegg prices.
I know the argument will be that the FX-55 and the 560 are two of the highest performing chips from the two camps. But the fact of the matter is that most people shopping for a 560 aren't going to be shopping for a FX-55. It's in an entirely different class.

Can you do a comparison between soundstorm and dolby digital live? What is the bitrate of the encoding? Frequency range? Overall quality?It seems like this may be the second time I pass on AC3 encoding though. Last time I chose a northwood platform over AMD and NF2, and this time I'll likely choose the NF4 over intel and dolby digital live.
Would be nice to be able to easily hook it up to my klipsch dolby digital decodor though...
