The PC4800 is basically opposite of VX as far as overclocking. The VX like volts, but this memory does not do much better with more voltage; actually, it might even do worse. The VX gained well from a burn in; with PC4800, anything you obtain out of the box is what you get.

I have seen TCCD marketed in two various ways. The first is with a low speed, low latency. TCCD was first memory after BH-5 enable to run 2-2-2-5. The other way it was sold was at a much higher speed, but also a higher latency.

TCCD can generally hit 200 MHz 2-2-2-5, and 260 MHz 2.3-3-3-7. OCZ assured these to run 2.5-4-4-10 at 300 MHz. I don’t anticipate these to go higher than their rating. OCZ also sells a PC5000, at 625 MHz, so something that could run at that speed probably was thrown into higher speed bin. The memory must have a little more head room; the lower latencies go untested, so there might be some good speeds in this RAM.

For stability, I ran every speed and latency through a few loops of Memtest86+. This is what I obtained with OCZ Platinum PC4800:

• 225 MHz 2-2-2-5

• 290 MHz 2.5-3-3-7

• 305 MHz 2.5-4-4-10


I was not able to obtain much more than stock 300 MHz. I tried to loosen timings to that of PC5000 version, and tried to reach that level. I executed memory through Memtest86+ and got many errors. It seems like this memory does not have many head room. If you want bit of extra speed you can get with PC5000, you want to pay for it. OCZ hand tests their memory, which is generally a good thing, but here it keeps you from getting some better speeds.

These modules are acceptable up to 3.0 volts, but TCCD does not like additional voltage, and results with more volts than stock were not higher. The lower latency speeds are bit higher than comparative memory. Relaxing the timings gives great boosts in stable speeds.
