DDR2 needs to evolve as high-end memory

post #1 of 9

DDR2 IS INCHING close to the 600MHz clock /1200MHz DDR throughput/PC9600 grading - let's use the correct description after a complaint from a Micron guy - but are all these complex looking heat sink and cooling systems really helping you crank up the last MHz?
The argument is that, to overclock more on the bandwidth side, you have to up the voltage, and so increase the heat output of the DIMMs - and yes, huge, finned heat spreaders or liquid cooling or whatever are needed to take away that heat.

How much do they really help? Early this year, I had a 2x1GB set of Micron DIMMs, declared DDR2-667CL4 - standard fare without any heat spreader. There was also Crucial Ballistix DIMM set, same 2x1GB, with full heat spreader and, supposedly, same declared speed and chip type (both were out of the fabs in the same 4Q 2005). Guess what? both overclocked to DDR2-800 CL 4-3-3-10 at 1.9 volts easily, but higher voltages of 2.0 and 2.1 volts didn't help get better latency. Of course, the Intel 975X couldn't exactly do more than DDR2-800 on an Intel board anyway, so I couldn't push the bandwidth further.

Bump. I'm not smart enough to understand.

you can get the same oc on the ram with or without good cooling... true

but running the ddr2 at 2.4v with no heatspreader is pretty retarted if you ask me and im sure the temps have to be degrading the memory somewhat

most people dont keep ram sticks long enough for it to really become a factor...

but the one time your ram stick does die 1 year after and you try to get the warranty and they are like "wheres the heatspreader?" you are going to feel like a real badass

overclocking the **** out of some ram without a heatspreader is like doing 150 on a motorcycle without a helmet... something is going to die

dont say i didnt warn you

i like the inquirer most of the time, they stay on top of their game more than most websites and aren't afraid to post 'rumors'

however when reading it you have to take it with a grain of salt and use your brain

uh ok, so how exactly does a heatspreader with 1/4" wide piece of thermal tape actually help cool anything, sure it may help that little spot but itll insulate the other sections of the ram,

as for me i dont think that heatspreaders are worth it if you have any type of active cooling, i took my heatspreaders off my ram and i use two amd stock hsf's that sit over them to keep them cool, most thermal tapes dont have a decent thermal conductivity worth using (imo) and noones has used opper heatspreaders since ocz way back when, everyone uses aluminum now that is about literally half as good as copper

get decent cooling in your case and you dont need them

Heat spreaders are just for show. I leave mine off @2.3V 24/7.

Plus it looks good when you see D9MGH on it.

Mmmmm, naked ram.

i like the look of heatspreaders, looks like your ram is tanked

I would be afraid of taking me heat spreaders off due to the led's but from my stick of non heat sink ram vs the stick I have now with heat spreaders they seem to both get just as hot at the same voltages.
