Overclocking The Crucial PC2700

Our overclocking adventures didn't start off very well which was a bit of a downer, but then again a challenge is just as fun sometimes. We were originally going to use the Abit KR7A-133RAID to test the Crucial PC2700 but we weren't able to get the RAM to run properly with the board.

At 133 MHz the memory didn't have any problem, but at 166 MHz we were not able to get the RAM to run properly with the most conservative memory timings. This might have been an Abit glitch as we even set the voltage to 2.85V in a fruitless attempt.

Because of the performance issues associated with the VIA KT333CE chipset, we were a little bit hesitant about using the 8K3A+ for these tests, but decided to go a head anyway as this is a pretty popular motherboard at the moment.

The Crucial PC2700 seemed to like the 8K3A+ much more then the ABit, and ran at 166 MHz FSB without any problems. Unfortunately our PC2700 DDR wasn't very overclocker friendly. We hit our first barrier at 170 MHz FSB; over 166MHz, but not by much.

The system would post at this speed but would blue screen when loading up Windows XP. We had to bump the memory voltage up to 2.7V for the system to run stable. With the most aggressive timings, we were able to get the Crucial PC2700 to run at 180 MHz FSB, but any higher and we would BSOD once we hit the Windows desktop.

The 8K3A+ does allow for voltages to go up to 3.2V which is nice, but it didn't help us overclock any higher. Setting the RAM by SPD allowed the Crucial PC2700 to run at 190 MHz FSB which sounds really good, but because of the relaxed memory timings the RAM didn't perform as well.

Sandra is designed to test the theoretical power of a complete system and individual components. The numbers taken though are again, purely theoretical and may not represent real world performance. Higher numbers represent better performance.

Memory Benchmark (FSB/Memory)

1. Integer ALU - 256MB Crucial PC2700 DDR (166/333 MHz) 2546 MB/s
2. Integer ALU - 256MB Crucial PC2700 DDR (180/360 MHz) 2621 MB/s
3. Float FPU - 256MB Crucial PC2700 DDR (166/333 MHz) 2361 MB/s
4. Float FPU - 256MB Crucial PC2700 DDR (180/360 MHz) 2604 MB/s

The Crucial PC2700 DDR performs quite well in Sandra - the bandwidth is on par with KT333CE based motherboards. We decided to use an actual 166 MHz FSB instead of a 133 MHz with the RAM running +33 MHz since the bandwidth there is only a lousy 2102 MB/s ALU and 2047 MB/s FPU.

PCMark 2002 Source: MadOnion

PCMark is a new benchmark from our pals at MadOnion which a whole system benchmark. It can be used on desktop PC's, Laptops and even Workstations and tests everyday computing from home to office usage. PCMark specifically stresses the CPU, memory subsystem, graphics subsystem, hard drives, WindowsXP GUI (if WinXP is used), video performance and even laptop batteries. This benchmark was released March 12, 2002 and can be downloaded from Madonion if you would like to give it a test run on your computer for comparisons sake...

PCMark likes those high FSB's and the Crucial PC2700 does very well also. Overclocking brings a nice speed increase.
