18 is #1 showed us that in raw benchmark performance, DDR2 1066 provides substantial performance gains, even at 5-5-5-12.

What RAM were you using, anyhow?

Intel processors almost always perform better with more RAM speed vs. tighter timings (as the image above illustrates).
Now that I think about it, my RAM changed from about 740 to 780 MHz around that time too. I was struggling with computer instability, but it turned out to be an undervolted CPU. I should play around with my RAM tonight...

You won't hurt anything, but those are Powerchip ICs and won't do 900 MHz at 4-4-4.

Change the RAM/FSB divider. Try 5:6 5-5-5 and 4:5 5-5-5.
Measure with Everest instead of 3D and you take the VGA card out of the equation.

Anyone with benches, perhaps? Any testimonials regarding a speed increase with an upgrade from DDR2 800 to DDR2 1066?

So, worthwhile or just a waste of money?
1066 @ 5-5-5-15 is better than 800 @ 4-4-4-12 in almost all cases... especially with intel, which tends to favor memory clock over tightened timings... will you see much difference between the two though? yes - you'll probably notice slightly faster load times... but in game performance probably won't raise a single FPS

It's really your call as to whether it's worth the extra cash.. personally, with 4GB of DDR1000 (5-5-5-15) @ $45, how could you say no?

1066 @ 4-4-4-12 would require some very nice chips... infamous d9 ballistix for example... I highly doubt your memory will handle it personally, but if you intend to test it, make a bootable version of memtest to avoid corrupting your OS

try it and find out. bench it yourself lol. My 1066 chips run MUCH faster at 1066 (5-5-5-15) than they do at 800 (4-4-4-12)

Real world performance wont be huge, but slightly noticeable. I ran my 800mhz ram at 6-6-6-18 and didnt notice any difference from 4-4-4-12 at 800, so now that you have read all that, simple answer:

YES. ITS WORTH IT TO GO 1066 AND LOOSER TIMINGS

All right, thanks guys. I'll expend some more cash for the 1066 RAM.

If your on an intel platform, higher frequencies are more beneficial than tighter timings. So go for higher than tighter.
