Gigabyte 8N SLI Quad Royal: Overclocking

FSB Overclocking Results

Front Side Bus Overclocking Testbed
Processor: Pentium 4 Prescott LGA 775
840EE Dual Core 3.2GHz
CPU Voltage: 1.4125V (1.4V default)
Cooling: Gigabyte G-Power
Power Supply: OCZ Power Stream 520
Maximum CPU OverClock 245fsb x 16 (3920MHz) +23%
Maximum FSB OC: 272fsb x 14 (3808MHz) +36%

Oddly enough, the ability to increase the front side bus even further than stock when dropping the multiplier to 14 just wasn't there with the shipping BIOS on our test board. We contacted Gigabyte about this issue and they were able to implement changes within a new BIOS that allowed the 840EE to reach 272 fsb with a 14x multiplier.

Memory Stress Testing

Memory stress tests look at the ability of the Gigabyte 8N SLI Quad Royal to operate at the officially supported memory frequencies of 533MHz and 667MHz DDR2 at the best performing memory timings that the Corsair CM2X512A-5400UL revision 1.3 will support.

Gigabyte 8N SLI Quad Royal
Stable DDR533 Timings - 2 DIMMs
(2/4 slots populated - 1 Dual-Channel Bank)
Clock Speed: 200MHz (800FSB)
Timing Mode: 533MHz - Default
CAS Latency: 3
RAS to CAS Delay: 2
RAS Precharge: 2
RAS Cycle Time: 4
Voltage: 2.1V
Command Rate: 1

The Gigabyte 8N SLI Quad Royal was completely stable with 2 DDR2 modules in Dual-Channel at the settings of 3-2-2-4 at 2.1V.

Filling all four available memory slots is usually more strenuous on the memory subsystem than testing 2 DDR2 modules on a motherboard.

Gigabyte 8N SLI Quad Royal
Stable DDR533 Timings - 4 DIMMs
(4/4 slots populated - 2 Dual-Channel Banks)
Clock Speed: 200MHz (800FSB)
Timing Mode: 533MHz - Default
CAS Latency: 3
RAS to CAS Delay: 2
RAS Precharge: 2
RAS Cycle Time: 4
Voltage: 2.1V
Command Rate: 1

The Gigabyte 8N SLI Quad Royal was completely stable with 4 DDR2 modules in Dual-Channel at the settings of 3-2-2-4.

We will now increase the memory frequencies to 667MHZ to see what effect this change has on the memory timings and stability of the board.

Gigabyte 8N SLI Quad Royal
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: 3
RAS Precharge: 3
RAS Cycle Time: 8
Voltage: 2.1V
Command Rate: 1

The Gigabyte 8N SLI Quad Royal was completely stable with 2 DDR2 modules in Dual-Channel at the settings of 3-3-3-8 at 2.1V and leaving the Command Rate at 1. We will now try 4 modules at this speed.

Gigabyte 8N SLI Quad Royal
Stable DDR667 Timings - 2 DIMMs
(4/4 slots populated - 2 Dual-Channel Bank)
Clock Speed: 200MHz (800FSB)
Timing Mode: 667MHz - Default
CAS Latency: 4
RAS to CAS Delay: 4
RAS Precharge: 4
RAS Cycle Time: 16
Voltage: 2.2V
Command Rate: 1

The Gigabyte 8N SLI Quad Royal was completely stable with 4 DDR2 modules in Dual-Channel at the settings of 4-4-4-16 at 2.2V with the Command Rate left at 1. This resulted in a slight decrease in benchmark scores during testing, but did not have near the effect of decreasing the scores when changing the command rate to 2. The command rate had to be switched to 2 once we passed the 675MHz level on this board.

    WTF?? Man who cares about gaming? As if it matters that u have 10 displays for a game?? This has to be designed to be perfectly suited to multichannel VIZ and Sim, a graphics cluster killer before clusters even took off, AKA where SGI and E&S have played for ever. This could be the final nail in the coffin.... my heart bleeds ;) think about it 4 genlocked quadro’s for 8 edge blended quad buffered channels, this is the sort of thing you drive planetariums and VR centres with *NOT* games.

    Where can I get one ?

    No mention of an (Athlon CK804) driver for the South bridge: http://www.anandtech.com/mb/showdoc.aspx?i=2561&am...">http://www.anandtech.com/mb/showdoc.aspx?i=2561&am...
    Only for the North bridge:
    "System Platform Drivers: NVIDIA nForce4 SLI Intel Edition 7.13"
    Also: was the automated driver installer used, or was a manual "Device Manager driver" install routine required? Due to the mix of the Intel N. bridge and an AMD S. bridge?
  • Gary Key - Friday, October 14, 2005 - link

    Actually, only the Intel driver set is required. I will post a more detailed response later today. We used the automated installation program and you will find the Intel MCP is just a subset of the AMD CK804. I have actually used the Intel IDE drivers on my Nforce 4 board as an example.

    one 2405FPW and two 1704FPV's.

    and the answer is..................

    Email me and I will setup a test configuration for you as I will have that same monitor delivered next week.

    I couldnt find the link in order to download the BF2 AT demo, so I can benchmark myself.
    Anyone found it?

    Nice review, BTW, Hope Nvidia support this board in future drivers just to see 4 Video Cards Benches.
    BTW, I wouldnt buy this board, it isnt available for the best Gaming Processor.
  • JarredWalton - Thursday, October 13, 2005 - link

    It's still "beta" from my perspective, and it hasn't been published. My next article with benchmarks will hopefully include the demo and other required files for running the BF2 benchmark, but just FYI, it isn't meant for non-technical types. You'll have to edit a batch file, and it doesn't automatically set BF2 settings (other than resolution) - it just runs with whatever settings BF2 is currently using. Stay tuned....

    Good stuff on adding to the range of games used for benchmarking, and a most excellent choice in BF2 as AT reviews have been lacking in benchmarks using FPS games lately. Adding a seventh FPS title when there are none from any other genre (except Aquamark 3 which is dubious at best as a representative sim) was a great idea as FPS games are all anyone plays at AT. If the recently released Serious Sam 2 is as fun as the two episodes of the original Serious Sam, it might be worth adding that too.

    But seriously, whilst taking the time to add BF2 to the benchmark suite is probably a good idea as it is very popular, you really should consider games other than what you like-- such as racing, flight/space-sims, above-view RPG, RTS, etc. It's no wonder the benchmarks are all so predictable with the main difference between gfx-cards being OpenGL and Direct3D games, when all the games are basically displaying the same kind of scenes.
  • Gary Key - Friday, October 14, 2005 - link

    I actually ran benchmarks on Nascar SimRacing (Daytona on four monitors is incredible), LOMAC, Falcon 4- Allied Force, GTR, and Call of Duty 2. We firmly believe the standard benchmarks need some additions to represent the overall gaming experience. You will see some of these results (plus a couple of RTS/RPG) shortly in the next "SLI x16" review. As noted in our sound test we will greatly expand the information provided for on-board solutions shortly to also include the new Dolby Master Studio suites shipping with the SigmaTel 922x and Realtek 882m audio options. Once this board is released for production we will do a complete follow-up that will concentrate on multiple-monitor usage.
