This is for geil DDR2 6400 btw with an e6300 @ 3.15ghz.
I've finally managed to get 450mhz (3.15ghz) on me e6300 with the timings at 5-5-5-15. The geil won't run 4-4-4-12 at that speed (900mhz) so its the slacker timings for now. I know its accepted that amd processors like tight timings, and I assume core2duo processors like high speeds with slacker timings, is this correct.
If so, what is the max speed (about) this memory can do in the system below at 5-5-5-15 @ 2.1 Vdimm.
I know this is a general query, but I'd like a sort of ball park figure to aim for to save a bit of time finding the "sweetspot" as it were.
Thanks.

Just user SuperPI to bench different settings and see which gives you the best times.
 
I don't know how well C2Ds perform on a divider, but CPU speed is more important than memory bandwidth usually.

So slacken the timings to push the RAM and CPU as far as possible really.
 
Well atm I'm running 1:1 with me e6300 @ 450mhz, so the memory is at 900mhz, 5-5-5-15.
Incidentally, I've tried superpi and run it, but where do you view the results? All I've got is a few notepad docs with nothing in them showing times :confused:
 
The results are just the time it takes to do a run, the quicker the run the faster your system is running.

I use 1MB as it gives quick results, though I guess the larger tests like 8MBs or bigger would be more memory dependant.

Thanks mate, I just didn't know where to view the results. I ran 1meg and 512 and got 18secs and 7secs respectively. how do those results look to you?
 
ddr2 at 3.3.3.8 pc6400 speed is the excact same as running
ddr2 1000 at 4.4.4.12 so the intel do like tight timings.
