Active Memory Cooling and other issues....

post #1 of 40
Thread Starter 
Came across this little gem in my search of online retailers



http://www.overclockers.co.uk/showpr...odid=MY-123-CS

It is designed for the purposes of cooling the new high voltage corsair Dominator DDR2 modules but thought it would make good cooling for both DDR2 and older BH-5 type memory modules which require higher than JDEC SPD specs.

If I can find a way to fit this around my Thermalright SI-120 or replace the HSF for something that will fit in conjunction with the Corsair cooler.

At this moment in time I dare not put more than 3.2v through my BH-5 as they get toasty.

This is how much space I have, bearing in mind the fan is 80mm and the motherboard is not mounted in a case at this point.


Any CPU coolers that will not impede the memory modules or the fitting of the corsair fan but still perform as well as the SI-120 or better. Jesz I wish I had a WC block on that CPU, it would cut out all this hassle.

What are your thoughts guys?

Has anyone seen proof that active memory cooling is necessary? Not just hype for memory companies to jack up prices. I have only seen two overclocking tests comparing memory cooling. The results were 0-3MHz gain... hardly compelling to pay extra for OCZ watercooled memory.
Once again...

You could epoxy a couple 40, 50 or 60mm fans together and find a way to rig them over the RAM

Yes

It means I can run my memory at >DDR400. Since I need ~2.9v to run them at stock with 1.5-2-2-5 timings. If I increase the operating frequency of the RAM to say DDR500 @ 2-2-2-5 I need 3.4v which without active cooling they would burn out

Memory cooling is only needed if you exceed JDEC SPD specifications for DDR and DDR2

Yeah thought about this but I move my PC round a fair bit so it needs something that is fairly robust mounting

It is necessary when you run +3.3V on DDR1, and +2.2 w. DDR2

Yeah since the Corsair DDR2 modules that this fan was designed for run at 2.4v then thats why its nessessary

Here is another option:

This is nice as it is not hardware specific. I picked one up for like US$13.99 to experiment with.

Have a look at this then.... preinstalled watercooled memory by OCZ that can run 1200MHz+.
Once again...
