Is there any advantage of using memory that has a heatsink? IMHO this could possibly have a negative effect say if you had a bank of 4 each with a heatsink. These are obviously close together, ie less airgap between chips than if without a heatsink, just somethin I though of when nothing better to do

If you get something with fins sticking out of the top (like Corsiar dominators or something) you can fill them up without hurting cooling performance.

You can happily run, even overvolted D9 RAM with no heatspreaders, as long as you have a fan blowing over them.

Heatspreaders = Myth
I havent seen any benefits at all when using them
Clunk has a good point, it really does depend on the thermal profile of your system, however. But I think I saw GeiL doing high performance RAM without any heat spreaders at all, good quality chips shouldn't need a heat spreader, since it goes without saying that cooler chips use less energy and have a greater chance of overclocking nicely, if that's what you want to do with them, but generally RAM runs laps around the FSB anyway so that's a bit pointless.
what about the OCZ Flex stuff with the water-cooling barbs on them? worth it?
There are 2 different types
Heatsinks and Heatspreades
Most companies have heatspreaders - some sinks are out there, the Corsair DHX does make a thermal difference but it can come down more to IC/Mainboard combination but most of the time you are doing these things to give you more chance and eliminate something else being the fall over.
I'd like all my memory to have some sort of spreader on it - for protection at the very least...
I would recomend DHX especially when using on 680i chipset mothrboards, the fans are good with DHX but as clunk suggests if you can get a good normal fan blowing on these it tends to be quieter.

I seem to recall a test/review that Crucial themselves did where they stated that adding wrap-round heatsinks to memory modules had no real benefit and if the heatsink/contact with the memory chips was bad could actually result in heat-spots and heat vortexes under the sink due to trapped heated air.
Have to admit that this was at the time that Crucial RAM came with no heatsinks so maybe they were justifying this as no adays their Ballistix range comes with heatsinks.
Actually, those were the ones I was talking about.what about the OCZ Flex stuff with the water-cooling barbs on them? worth it?
Mine used D9GMH chips, which OCZ have given a rating of 2.2v - 2.4V, which, as you can imagine, gets very hot.
The odd thing about those heatsink things, is that they dont get hot at all, even with 2.4V going through them, apart from the very tip of the heatsink that is closest to the RAM slot.
They died pretty quickly, and I can only conclude that the heatspreaders kept the heat in.
The same thing happened with Teamgroup RAM that had D9GMX chips, rated at 2.3v-2.45v, these had the Thermalright heatsinks on them, but the same thing happened again, and on these, the problem was more apparent, and it was the thermal pad that sandwiches between the heatsink and the RAM chips. It was too thick, and was acting as an insulator rather than a conductor of heat, so naturally, the chips died, however, I had another set that I didnt use with the heatspreaders, and they lasted much longer.

B*gger! I've got two of these - I'm on my second set too - the others.. died...
Depends what model you go for, I think the PC2-6400 ones use promos chips, and they dont even need heatspreaders.B*gger! I've got two of these - I'm on my second set too - the others.. died...
Its the 9200 and 9600 with the D9 chips
Which were yours?

9200s Clunk.. 'tis a long and sorry tale, I usually build my own systems but bought a custom one for my 35th birthday as a treat to save me the hassle.. Never again! (Let's just say I have a quad core and an early revision EVGA 122-CK-NF68 board.)
Ah well, thats probably the EVGA board that killed them with overvolting..ouch!
Cant you RMA it to evga and get the updated version?

Simple answer: Yes, probably!
More complicated answer: I initially had big problems which (it eventually transpired) were caused by a short from a sensor on a fan controller (it tooks weeks to get the bloody thing stable) so by the time it was running stablyish I'd had the board too long and also didn't want to be without a PC for x number of weeks again (personal choice) whilst they shipped a replacement. Also the wiring to the controller (a T-Balancer) looks pretty fiendish and I've always been bloody awful at cable management so the easier option was to leave it as it is.
I'll probably repent at leisure.. I already have, I suppose.. ah well..
It works now, just about, I just can't do too much with it overclockwise and it's a pretty warm system, despite being a TJ09 case with good airflow.. At some point I'll probably get a different mobo.. we'll see...
Heat spreaders are supposed to offer some protection against static, which lowers the return rates for the manufacturers. Hence Geil value ram has a spreader (or the DDR400 I have kicking about has).
I guess "static protection against Loser customers" isn't such a selling point.
