My guess is they are ,Has anyone else used ram sinks ,I use them on my pc3200(valuram) and they let me OC my ram 20% stable and with tighter timings.
Without them I had a 10% OC but only stable with the timings loosened a tad.

The reason I want feedback is that ive ordered some DDR2 6400 that come with heatspreaders and I want to know if it would be worthwhile to rip off the spreaders and apply some low profile bga sinks instead.
Has anyone done this ???
I realise this may waste some slots but I can get by with just 2gb for a while

Im assuming the ram chips are square like these?

If the spreaders are held on with anything like arctic epoxy I'll give the whole thing a miss

its all based on surface area. but if your memory doenst really get that hot, then it shouldnt make much of a difference. it should work, as long as you dont drastically cut down on the surface area of the heat spreader. and yes, the chips are square/rectangular. however, they are not the same size as VGA memory chips. those tend to be literally square, while the RAM chips are usually a little rectangular. (someone can correct me if things have changed since i have looked at them both, havent seen either in a while thanks to enormous heatsinks lol)

also, you might want to get a small fan to blow some air over the sinks since the area is more compressed with those heatsinks.

yes, they are useless. You can usually pull them off and get better temps with a simple fan over the chips.

if you dont have any airflow going on there worth while. otherwise there pointless

If I find some sinks to fit ddr2 im gonna try it.

Is this what my Corsair will look like under the bonnet?

How can they do that?????

Says in the review they are bonded now ,quite an old review though...
Should have bought Micron ,sans spreaders.

i saw an article, cant find it now, they tested the same ram with and without heatspreaders, OC difference was about 5mhz

They're nice for protecting the chips but thats really about it, especially if they aren't adhered to the surface correctly. About 5 years ago I had some fly-by-night place sell me DDR266 labeled as DDR333. They used regular 3M double sided tape to hold the heatsink on. When I finally ripped the damn things off I found out about the misdeed because the DDR266 label was still on the damn stick!!! Of course it said DDR333 on the heatsink...

No wonder I had half a year of instability. This is my story of how I dislike heatsinks on ram. ;)

Now that's a no-no.

The DDR I bought 2 years ago had double-sided (thermal?) tape on them. Is Corsair going bad? :(

Those ram sticks look pretty ancient ,I think they smartened up their act since then.
