Gigabyte 8GPNXP Duo: Overclocking and Stress Testing
FSB Overclocking Results
| Front Side Bus Overclocking Testbed | |
| Processor: | Pentium 4 Prescott LGA 775 560 ES (2.8GHz-3.6GHz) |
| CPU Voltage: | 1.425V (1.3875V default) |
| Cooling: | Thermaltake Jungle 502 |
| Power Supply: | OCZ Power Stream 520 |
| Maximum CPU OverClock: | 218x18 (3996MHz) +9%/td> |
| Maximum FSB OC: | 218FSBx14 (+9%) |
With the recent introduction of Intel Speedstep, overclocking an Intel 775 CPU can be done by raising the FSB at the stock multiplier or by lowering the CPU to 14X ratio and then raising the FSB more. Therefore, we ran all OC tests at the stock ratio and at the 14X Speedstep ratio. The ratio really didn't matter on the 8GPNXP-Duo as we could only reach 218 at any ratio. It appears that Gigabyte has more work to do on the 8GPnXP-Duo to get around the 10% OC lock. Since Gigabyte managed this task on the sister 915X chipset 8ANXP-D, this may still be possible with BIOS updates.
Memory Stress Test Results:
The Gigabyte can use either DDR or DDR2 memory. Benchmarks were run with DDR2 memory and a memory stress test was run to measure the ability of the Gigabyte 8GPNXP-D to operate at its officially supported memory frequency (533MHz DDR2), at the best performing memory timings that Crucial/Micron PC2-4300U will support. Memory stress testing was conducted by running DDR2 at 533MHz (stock 3:4 ratio) with 2 DIMM slots operating in Dual-Channel mode.| Stable DDR533 Timings - 2 DIMMs (2/4 DIMMs - 1 Dual-Channel Bank) |
|
| Clock Speed: | 266MHz |
| Timing Mode: | 3:4 (200:266 - Default) |
| CAS Latency: | 3.0 |
| Bank Interleave: | Auto |
| RAS to CAS Delay: | 3 |
| RAS Precharge: | 3 |
| Cycle Time (tRAS): | 10* |
| Command Rate: | N/A |
Like the other motherboards in this 915 roundup, the Gigabyte was completely stable with 2 DDR2 modules at the best performing settings of 3-3-3-10 at default speed and 1.8V default voltage.
Since the Gigabye can run either DDR or DDR2, but not both simultaneously, we could not test with 4 DDR2 DIMMs.

I been a Intel user since the first Pentium 3 came out now I have a Intel P4 3.0C I refused to spend more money on things I had already bought so I stayed with the 478 socket, seeing as Intel wants me to move to an expensive platform, I say I'll ditch Intel head with the AMD crowd, I'm sure I won't be the only one, maybe legions of intel campers will leave.ChineseDemocracyGNR - Tuesday, December 7, 2004 - link
About the config I put together in the previous post; does anyone know if the overclock lock on the 915P chipsets apply to lower FSB's too? Could I overclock the 133MHz Celeron D to 200MHz on any 915P motherboard?ChineseDemocracyGNR - Tuesday, December 7, 2004 - link
The 915P chipset provides good value for the money. For example:ECS 915P-A $79
Intel Celeron D 325J 2.53GHz $88
Albatron GeForce 6600 128MB $120.50
or
Albatron GeForce 6600GT 128MB $190.50
(newegg prices)
The processor can be overclocked to 3.6+GHz very easily, much like the Athlon Mobiles.
That makes a good budget gaming rig, better than anything you could put together with an AMD processor for the same money. So, at least in my opinion, AMD has a better mainstream/high-end processor, and Intel wins the value segment. Who would say?

I have now read the entire article, and oh boy! Though I prefer to read about socket 754/939 motherboards, this has to be the best motherboard roundup I ever read. Ever. Well done.

#22,
thank your fixing it. The typo I wrote about on page 10:
"The fact that Asus manages a higher OC than more recognized OC boards like DFI and Asus "
Don't you mean ABIT in the last word there?

#21 - The Foxconn results have been corrected on p.20. Thank you for bringing it to our attention.ChineseDemocracyGNR - Tuesday, December 7, 2004 - link
A few typos:"The fact that Asus manages a higher OC than more recognized OC boards like DFI and Asus "
page 10.
On page 20, the "Front Side Bus Overclocking Testbed" table is probably wrong.

Good article.

Why does only the socket 915 get a 16mb cache Hard Drive?danidentity - Tuesday, December 7, 2004 - link
Wes, I said thanks before but I'll say it again, great roundup. We appreciate your hard work, always.danidentity - Tuesday, December 7, 2004 - link
Live -The P5GD2 is expensive compared to most boards, but it includes a ton of stuff, like 8 SATA ports, dual gigabit LAN, on-board 802.11g/b, and on-board hi-def audio with Dolby Digital Live (realtime encoding, like SoundStorm).
Most 915P boards aren't as close to as expensive as the Asus. The Abit AG8 is ~ $130, equal or cheaper in price than the K8N Neo2.

#16 - After I did the price analysis today I changed "outstanding value" to "good value". Thanks for the comment about the review being good reading. It is appreciated as a huge amount of work went into this roundup.
