OCZ Platinum Edition PC2-4200 EB - Overclocking on the AM2 Platform
(Page 5 of 5 )
Those who have used both Intel and AM2 platforms will know that overclocking results can vary vastly between the two. I’ve included this section so that AM2 users can know what to expect from this memory.
The sticks were equipped in dual channel configuration on the below set up.
The test bed:
- DFI Lanparty UT NF590 (nForce 590 SLI based)
- AMD Athlon 64 X2 3600+ AM2
- Gainward 7300GT
- 2x1GB OCZ Platinum Series PC2-4200 EB (533MHz 3-2-2-8)
- Windows XP-64
- WD 74GB Raptor
I was still unable to provide greater than 2.2V, definitely indicating that the problem was in the sticks, and not the board. In addition, I was not able to POST at a tRP or tRCD of 2 on this board.
The following table shows the maximum clocks I was able to reach at each respective timing set.
Timings (tCl-tRC-tRP-Command Rate) | Maximum Overclock |
3-3-3-1T | 700MHz |
4-3-3-1T | 820MHz |
5-3-3-1T | 835MHz |
5-4-3-1T | 835MHz |
5-5-3-1T | 835MHz |
3-3-3-2T | 700MHz |
4-3-3-2T | 920MHz |
5-3-3-2T | 986MHz |
5-4-3-2T | 990MHz |
5-5-3-2T | 996MHz |
Though 2T does cause a significant performance loss, it did allow me to overclock this memory to astonishingly high levels. In fact, I was able to get Super Pi 1M stability at 1000MHz, however we could not past 32M at higher than 996MHz. Though I’d have to say being within 7% of the magic 100% overclock is nothing to snarl at. 1T, however, offered less than impressive clocks, being topped by the Intel set up at every timing level.
Conclusion
Without a doubt, these are some fantastic sticks, both at default clocks and especially when overclocked. Though they are beaten by their fellow D9 based rivals at both stock and overclocked, they are probably the cheapest Fatbody D9s on the market and with little doubt, the best PC2-4200 sticks on the market.
Pros
- Very tight timings at default clocks.
- Great value to overclockers at tight timings.
- Very cheap for Fatbody D9 based memory.
Cons
- Far more expensive than the average PC2-4200 kit.
- Low quality PCB limiting vdimm, thus limiting overclock.
