If you had a choice what would you buy and why?

Keep in mind bot have the same timings at 5-5-5-15 T2 and both use Micron D9

I'd get whatever is cheaper.

Unless you're going to be pushing your CPU past 533Mhz FSB their overclockability will not matter. As to the performance in general, there probably isn't any noticeable difference between DDR2-667 and DDR3-1866.

I am only asking to see what others think I actually have both kits sitting on my desk :D Both have been benchmarked and there is only 1 clear winner :cool: More on that latter tho lets see what the forum members think first

There's none at all. According to some benchmarks I read recently, in games, the difference between DDR2 800 and DDR3 1366 - and this is memory costing around 10 times what DDR2 costs - is 0.26%. That's a quarter of a frame per second faster if you're running at 100fps. For 10 times the cost.

I'm sure they only sell the stuff for the lulz.

Both kits provided the same numbers so you gotta wonder what tis the better buy? Well the OCZ has a higher voltage tolerance for OCing and to top it off they have a better heat sink design :)

I'd use the one that is worth less on ebay.

I'm sure you can see where I'm going with this... :lol:

If you aren't selling anything though, the OCZ heat spreaders are pretty nice. I liked that on the 1066 I had. Then I sold it on ebay for $125 and bought twice as much memory of a different brand for $170. :lol:

No idea. I don't overclock my memory because it does nothing, so I don't even worry about it. :p

Buying expensive memory is like buying expensive rims for a car you leave in your garage all year... :p

11-27-07, 02:23 PM
that depends I bought these D9's so I can run at 1066 with 5-4-4-12 timing VS 5-5-5-15. I know its a high price to pay $250 for 4GB vs $160 for cheap-o ram but It gives me a edge in benchmarks and e-penise rep. :D

Yeah, I guess if you benchmark and need every last point you can get then ram is one (extremely expensive) way to boost your scores a bit.

I don't really run synthetic benchmarks too much any more though so I don't worry about it.

Its saved me an awful lot of money, thats for damn sure. :o

I love there new sexy black PCB's they been using them now for 2 months (nana2)

You get used to it. I mean heck my mobo says Nvidia/EVGA, my GPU says EVGA, Nvidia SLI on the connector... it only makes sense that my memory says it. Even my north bridge chip set fan glows green (nana2) I'm half tempted to chuck the 120 Ultra and put a green Zalman in there!!! :p

I had that same stuff. Didn't have the black PCB though.

Worked great while I had it. This WINTEC stuff doesn't run any different though.
