Benchmarks at highest speed using tightest timings
Overclocking these Samsung TCCD “f” revisions chips proved to be quite different from others when it came down to voltage tolerances. Whereas Winbond’s chip loved high voltage up to 3.6VDDR, you generally won’t gain any overclockability going past 2.8v. There is also potential to decrease OC at volts even from 2.7-2.8v. Keep in mind to vary vdimm through all testing to make sure your set is being given the voltage that best fits your individual modules. That said, according to a member of
a performance ram manufacturer, recent production of TCCD based chips could potentially benefit from voltages over 3.1v. The memory sticks in this roundup did not react to these higher voltages, leading me to believe they still have the earlier revision.
The OCZ EL PC4400 sticks were also tested with different voltage settings with the aid of an OCZ DDR Voltage Booster
unit, but no difference in performance was obtained by going from 2.7 to 3+ VDDR.
In this first OC test we leave the timings at CL2 2-2-5 (except for the OCZ PC4400) and by using Memtest86+ 1.27 try to find the sweet spot for each pair of memory sticks, we then booted into Windows at the maximum speed and ran through our benchmarks to check on stability, PiFast, 3Dmark2001SE, Sisoft Sandra 2004 and UT2003 were used to evaluate performance increases.
While most sticks delivered equal performance, it was OCZ Platinum Rev2 which takes the lead here. The OCZ PC4400 scores high here due to its more relaxed timings.
PiFast not only likes low timings, but also high CPU speeds, this explains the lead of OCZ PC4400 gigabyte kit. Plat Rev2 follows closely.
The OCZ Plat Rev2 takes the lead again, but only with a small margin.
Sisoft Benchmark reflects the results from the 3DMark2001SE run.
Here performance difference in Flyby is negligible, but the Botmatch sees a larger difference between the top performer and the rest of the pack!
Overclocking at tight timings with the Samsung TCCD tested today does not make us relive the Winbond days of yore, with an average of 209-216Mhz it’s a far cry from those 230-240Mhz overclocks.
Is this current crop of Samsung TCCD no good then? Let’s turn the page ->
