Performance Shootout: DDR3-1800 from Different Memory Makers
All in all, we have already tested five kits of overclocker DDR3 SDRAM designed to work at 1800MHz+ frequencies. Besides the solutions from Cell Shock and Patriot we have just talked about, we have also reviewed memory kits from Corsair, OCZ and Super Talent (see our article called DDR3 Accelerates: DDR3-1800 SDRAM Roundup for details). So, we decided to compare all the memory kits so that we could make more justified conclusions.
The diagrams below show the maximum frequencies achieved in our lab with different memory kits. The first diagram sums up the results obtained with timings set as 7-7-7-20.
Low (for DDR3 SDRAM) memory timings of 7-7-7-20 are defaults for Corsair Dominator TWIN3X2048-1800C7DF G modules. That is why this particular memory performs best of all here: it can run stably at up to 1860MHz frequency. Cell Shock kit took the second prize. These modules remained stable at maximum 1808MHz. Other modules failed to overcome the 1800MHz barrier with their timings at 7-7-7-20.
The tests revealing maximum frequency with 8-8-8-24 timings showed a completely different picture.
Here the laurels of a leader belong to Patriot PDC32G1866LLK: this memory has almost hit the psychologically important 2GHz barrier. The second place is against taken by another today’s testing participant – Cell Shock that runs at up to 1908MHz speed.
In conclusion I would like to sum up the most aggressive timings with which our tested memory kits can run at the “base” 1800MHz frequency:
DDR3-1800MHz: best timings (2.0V)
Cell Shock CS3222580
Corsair Dominator TWIN3X2048-1800C7DF G
Super Talent W1866UX2G8
OCZ PC3-14400 Platinum Edition
I don’t think any commentary is needed here: the best latency combination at 1800MHz belongs to Corsair and Cell Shock kits.
We have already discussed the performance of systems with DDR3 SDRAM, which frequency and timings were configured differently, in our previous articles. Please see the following reviews for more information on the topic:
