slow timings: 203MHz slower than 179MHz?

I finished testing my new memory now!


I have a better score w/ 179x13 = 2327MHz than w/ 203x11.5 = 2335MHz. I think, the timings are the reason for this: at 179MHz I have CAS-TRP-TRCD-TRAS=2-2-2-7 as the fastest timings that work (Tras 7 is faster than Tras 5 and 6). At 203MHz the best is 2.5-3-3-8. The biggest difference makes the TRCD-timing.


Benchmark results (3DMark01SE, RAM:FSB=1:1 in all test):

179x13 = 2327MHz (2-2-2-7): 14238 (Prime stable 24 hours)
179x13 = 2327MHz (2-2-2-5): 14201 (not tested for stability)
181x13 = 2353MHz (2,5-2-3-7): 14102 (not tested for stability)
181x13 = 2353MHz (2,5-2-3-6): 14042 (not tested for stability)
181x13 = 2353MHz (3-3-3-8): 13947 (Prime stable 6 hours)
188x12,5 = 2350MHz (2,5-2-3-7): 14053 (not tested for stability)
188x12,5 = 2350MHz (3-3-3-8): 14057 (Prime stable 6 hours)
203x11,5 = 2335MHz (2,5-3-3-8): 14043 (Prime stable 30 min.)
203x11,5 = 2335MHz (3-3-3-8): 14081 (Prime stable 6 hours)


My question: Can I also expect in games, that 203x11.5 is slower than 179x13, just because the timings are lower althought FSB and overall clock are faster? What setting do you think is the fastest in games?


About memory-voltage: I use 2.77V and this will not change, if it isnt stable at a lower voltage: I have posted in 32 forums what voltage I should use and 32 people gave replies, which answered the question: 16 (50%) said, that I should use 2.9V or more, 13 (40.6%) said I should use 2.77V and 3 (9.4%) said I should use 2.63V. I will test, if 2.63V is also stable at the best setting I can get w/ 2.77V.

If someone wants to know something about my memory voltage or finds a different voltage better: please post here.

It looks like most of your 3dmark scores are all well within the error margin.. looks like you'll just have have to try on the games yourself and see if there is any difference.. although i seriously doubt there is.

The biggest differenc I got when using 3DMark01SE w/ the same setting was only about 40 3DMarks.

Also the result, that 179MHz w/ lower timings was better than 203MHz w/ higher timings was repeatable, I made 5 benchmarks w/ different timings w/ 179MHz and 4 w/ 203MHz, the worst timing w/ 179MHz was 2.5-2-2-6 (141170), the best timing w/ 203MHz was 2.5-3-3-8 (14043, I dont know why I get a lower score than w/ 3-3-3-8). The only timing which makes a big difference is TRCD (at least 200 3DMarks).
