OCZ Platinum PC4800 - Overclocking
(Page 3 of 6 )
The PC4800 is practically the opposite of the VX as far as overclocking. The VX loved the volts, but this memory doesn't do much better with more voltage; in fact, it might even do worse. The VX gained nicely from a burn in; with the PC4800, whatever you get out of the box is what you get.
I have seen the TCCD marketed in two different ways. The first is with a low speed, but also low latency. TCCD was the first memory after BH-5 to be able 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 commonly hit 200 MHz 2-2-2-5, and 260 MHz 2.3-3-3-7. OCZ guarantees these to run 2.5-4-4-10 at 300 MHz. I don’t expect these to go much higher than their rating. OCZ also sells a PC5000, at 625 MHz, so anything that could run at that speed most likely was thrown into the higher speed bin. The memory should have a little more head room; the lower latencies go untested, so there might be some nice speeds in this RAM. For stability, I ran each speed and latency through a few loops of Memtest86+. Here is what I got with my OCZ Platinum PC4800:
- 225 MHz 2-2-2-5
- 290 MHz 2.5-3-3-7
- 305 MHz 2.5-4-4-10
I wasn’t able to get much more than the stock 300 MHz. I tried to loosen the timings to that of the PC5000 version, and tried to reach that level. I ran memory through Memtest86+ and got tons of errors. It looks like this memory doesn’t have a lot of head room. If you want the little bit of extra speed you can achieve with the PC5000, you will have to pay for it. OCZ hand tests their memory, which is normally a good thing, but here it keeps you from getting some better speeds.
These modules are warranted up to 3.0 volts, but TCCD doesn’t like extra voltage, and the results with more volts than stock weren’t higher. The lower latency speeds are a little higher than comparative memory. Relaxing the timings gives great boosts in stable speeds.
Testing
My Pentium 4 CPU could not even boot at 300FSB, so I used my AMD computer. While it is not a great overclocker, it can still reach 300 MHz FSB thanks to its unlocked lower multipliers. Here is what the test computer looks like:
- AMD Athlon 64 3000+
- DFI nForce 4 Ultra-D
- X300SE
- Samsung 120GB SATA
- OCZ Powerstream 520 Watt
- Windows XP x64
The A64 has a Winchester core. There is also a fan blowing on the memory during these tests, as I recommended above. The memory was tested at 300Mhz with 2.5-4-4-10 as well as 290Mhz 2.4-3-3-7.
