Crucial Ballistix Overclocking
I was able to get the Crucials to run to 217MHz before I had stability problems. This was running at the very aggressive 2-2-2-10 settings Anandtech recommends for Athlon 64.
To get farther, you have to relax timings, I was curious to see what others folks experience was. The Crucial Ballistix 512MB Low Latency PC3200 DDR at www.bigbruin.com =- was a good guide.
bq. At 200 MHz, the timings on the Ballistix DDR were the afore mentioned 2-6-2-2, at 220 MHz I had to relax them slightly to 2.5-6-2-2, and at 240 MHz they were run at an impressive 2.5-8-2-2. Beyond 240 MHz I experienced various errors before, and once into Windows, no matter what combination of timings, voltages, and other BIOS settings I tried. _All of these were at stock 2.6V_.
“Anandtech”:http://www.anandtech.com/memory/showdoc.aspx?i=2145&p=9 had a similar experience in their review of the Ballistix. This was also on a Pentium 4 system. In that test he had:
| Speed | Clock | Timing | Voltage | Quake 3 (fps) |
| DDR400 | 200MHz | 2-2-2-5 | 2.5V | 329 |
| DDR433 | 216MHz | 2-2-2-5 | 2.65V | 359 |
| DDR466 | 233MHz | 2.5-2-2-5 | 2.65V | 384 |
| DDR500 | 250MHz | 2.5-2-2-5 | 2.65V | 410 |
| DDR514 | 257MHz | 2.5-2-2-5 | 2.85V | 419 |
Both of these test showed that the timings have to go from CAS of 2 to 2.5 somewhere in the 220MHz-233MHz range with an Athlon 64 and the MSI K8N Neo2, so hopefully, the Chaintech VNF3-250 will do as well.
Here is what I actually got. I haven’t benchmarked yet, but got these to run with stability. So a little less than the above, but certainly in the range.
| Speed | Clock | Timing | Voltage |
| DDR400 | 200MHz | 2-2-2-5 | 2.6V |
| DDR420 | 210MHz | 2-2-2-5 | 2.9V |
| DDR450 | 225MHz | 2.5-2-2-5 | 2.7V |
| DDR500 | 250MHz | 2.5-2-2-5 | 2.9V |
