EPOX 5LDA+GLI: Overclocking

FSB Overclocking Results

Front Side Bus Overclocking Testbed
Processor: Pentium 4 Prescott LGA 775
820 Dual Core 2.8GHz
CPU Voltage: 1.4500V (1.3000V default)
Memory Settings: 3-2-2-8 at 667MHz
Memory Voltage: 2.15V
NorthBridge Voltage: 1.60V
SouthBridge Voltage: 1.00V
Cooling: Intel 840EE Heat Sink
Power Supply: OCZ Power Stream 520
Maximum CPU OverClock: 257fsb x 14 (3598MHz) +28%

This board is a very good overclocker, considering that our best FSB x 14 was at 267 on the Asus P5LD2 Deluxe. At this overclock setting, the system was able to complete all of our benchmark test suites and also run Prime95 and SuperPI without issue. We were able to overclock the FSB to 265 at the 14x multiplier, which resulted in CPU operation of 3710MHz, but we were unable to complete the benchmark test suite. However, even at this setting, the board was stable enough to complete all of the gaming benchmarks. It must be noted that we utilized a newly released BIOS, as the first BIOS release would not overclock the FSB past a setting of 222. We are sure that Epox will be able to coax more out their BIOS in the coming weeks and hopefully will allow additional memory voltage settings.

Memory Stress Tests

Memory stress tests look at the ability of the Epox 5LDA+GLI to operate at the officially supported memory frequencies of 667MHz DDR2 at the best performing memory timings that the Corsair CM2X512A-5400UL revision 1.3 will support.

Epox 5LDA+GLI
Stable DDR667 Timings - 2 DIMMs
(2/4 slots populated - 1 Dual-Channel Bank)
Clock Speed: 200MHz (800FSB)
Timing Mode: 667MHz - Default
CAS Latency: 3
RAS to CAS Delay: 2
RAS Precharge: 2
RAS Cycle Time: 8
Voltage: 2.1V

The Epox 5LDA+GLI was completely stable with 2 DDR2 modules in Dual-Channel at the settings of 3-2-2-8 at 2.1V.

We will now install all four available memory slots, which are usually more strenuous on the memory subsystem than testing 2 DDR2 modules on a motherboard.

Epox 5LDA+GLI
Stable DDR667 Timings - 4 DIMMs
(4/4 slots populated - 2 Dual-Channel Banks)
Clock Speed: 200MHz (800FSB)
Timing Mode: 667MHz - Default
CAS Latency: 3
RAS to CAS Delay: 4
RAS Precharge: 4
RAS Cycle Time: 8
Voltage: 2.15V

The Epox 5LDA+GLI was completely stable with 4 DDR2 modules in Dual-Channel at the settings of 3-4-4-8 and needed the voltage increased to 2.15V. This is a very good accomplishment for a board targeted at the mainstream market.

    The other reviewers here at Anandtech offer their own style, thereby providing the "mix it up" factor. I personally don't think you need to adjust your style, as I happen to like the cultural infusion supplied by your literary quotes.

    Fair enough, I was just giving my personal opinion on the matter.

    What's wrong with being exposed to what the author believes to be wisdom? Surely you don't read these articles simply for the technical specifications; otherwise, you would read the spec sheet. Why, then, do you object to the author trying to relate an idea to you?
  • Furen - Tuesday, November 15, 2005 - link

    I read the articles for their technical merits. Spec sheets do not show how the different components interact with one another nor can they show performance, stability, etc; and, most importantly of all, they're made by the manufacturer, who is hardly to be considered an unbiased source. The problem with throwing a strong idea in front of the reader before giving him article is that this idea becomes the filter through which the rest of the article is viewed. This is, of course, very effective if you are trying to persuade the user to reach the same conclusions as you, but it skews the reader's ability to analize the purely technical merits of the products.

    What makes you so sure Conroe is the last P4? ;)

    Conroe isn't a P4. It's the next generation architecture that Intel has not yet named - also referred to as the NGATIHNYN. :p
