The ultimate in cooling. Phils next massive project

Never be afraid of trying something new everyone says to avoid watercooling there ram but no one i know has done it,so how do thaey know not to.Im going to give it a go for sure,im going to give it a bit of chiller action.

Looking forward to seeing the custom case,will it be losely based on the MM cases?

I know plenty of people who have done it and no benefits were reaped. U just ain't been in the scene long enough to. There used to be articles over at XS (when it first started) where they LN2'd ram... and didn't get it any higher than they could get on aircooling. Custom Phasechange was also tried. Last experiment I remember was done on Abit KX7-333R by MrIcee I think... This is all from YEARS ago, before nVidia were making mobo chipsets... and no longer shows up in most archives etc... gotta remember folks have been using watercooling, chilled water, and phasechange for near on 10 years now... takes some hunting to find the records of it all, but if it isn't in use in mainstream NOW, then it's cos it was proved to be pointless then and nothing has yet changed. In the case of memory and storage, any cooling over air is pointless unless you're talking a case where ambient temps are SERIOUSLY high.

Whether it be video or system ram, its cooling isn't what holds it back.

S'the usual problem in this scene... as the next generation comes along, the old generation disappears... along with their experiences inevitably.
 
I remember the Phase and LN2 cooled RAM but don't recall anyone trying water. Probably brushed over it tbh.

Thats good info there Marci cheers for that, think I'll wait till scorchio gets his blocks etc before I get mine.
 
What about using it to cool high voltafe ram like bh/ch5, ut? I know my redlines run 4mhz faster with a 120mm fan than with a 80mm fan. with the 80mm fan they produce errors in memtest at 540mhz but with the 120mm fan they dont error until 546mhz at 2-2-2-6 1t.
 
You maybe wont see any significant gain using watercooling on the ram but it does look the choppers. I havent decided yet whether we will go down the ram watercooling route or not. I will be speaking to the customer about it in due course.
 
I think the water would just keep them at a constant lower temp. I don't know and am speculating on it, only Scorchio will b able to tell us as he has blocks on the way :D
 
Hmm... just been back as early as XS gets (2002) and it ain't early enough for that particular article... but the basics were, once they'd voltmodded and applied heatsinks and a fan to the ram, they maxed it out. They then went onto extreme cooling... and could get it no further. Test was repeated on both vga and system ram with various methodologies, and in each case, the best achievable on aircooling was also the best achievable with any other method. They then went on to explain the whys and wherefores, and how no matter what happened with solid-state memory architecture, nothing would change until RAM itself changed... and it hasn't.

So, watercooling etc ram WILL work, but won't get you any better than aircooling so therefore fruitless from a performance angle....
 
I agree, I remember them designing blocks for watercooling the RAM, also peltier cooled ones... the temperature doesn't seem to have that much of an effect on memory speeds. My BH-5 at 266MHz during their current burn in don't even feel that hot with the fan on them...

Although on the other hand, it can look really funky! :D
 
What about watercooling high voltage RAM to allow more juice to be pumped through the sticks safely? No benefit there either?

:)

Nope... they ascertained that there was a max ram speed, to a point where even giving it 100% more voltage wouldn't get another 1mhz more... and that point was reachable with sinks and a fan blowing over em... and was also reachable WITHOUT any ramsinks etc... but minor stability issues.
 
Thanks Marci. :) That also makesme feel better about not having the best possible airflow over my RAM. As long as the voltage wont kill the sticks, I`m happy.

Anyway...lets give this thread back to the project :)

Well just got 6 of the new revision chilly1 heads turn up today 2 will be used on this project and I dare say one will go on my cascade :D

I remember reading this too, and this is why i am generally against full card waterblocks.

IMO watercooling RAM is only ever worth if it if you are looking for very low noise levels and have a seperate loop for things like the harddrives, power circuitry, RAM etc so that the added restriction and heat doesnt affect the CPU or GPU temp.

My 7800 GTX with DDR3 has not benefited from any kind of passive cooling ive tried
 
Even though air cooling keeps the ram cool it still runs at 35 degrees,well my bh5 did.No matter how i do it 1 120m fan or 2x80m it looks a mess the waterbloks should look cool;)
 
It depends on the ambient temperature I think.

If the PC room is lower than 20 degrees Celsius then direct air cooling onto RAM sinks is as good as you'll need to realise the full potential of the RAM.

Watercooling will add some benefit (I think) to warmer work areas being able to realise the maximum overclock (especially true if you are just looking for a single stable Mhz above where you are now).

Ram cooling is only restrictive if you have a line that goes 'cpu-ram-gpu's-pump-rad-res. If you installed a threeway manifold (like I know scorchio will) you will have one main feed branched into 3 lines (one for each GPU and one for the ram) and then the three return lines go back into a single manifold before returning to the RAD (or in scorchios case - chiller).

I also know in scorchios case a few degrees is the difference between the BH6 ram doing 270Mhz or 268Mhz - the latter being at sub 20 degrees ambient.

Being right on the ragged edge of how far the ram will go is ideal for trying the watercooling (or chilled water cooling route).

Having said all that Marci has been at this a lot longer than I have and has much more experience and I respect his knowledge and advice. It's lilel;y that hardly anyone will benefit from this but I know scorchios rig and hos ram and I know that few degrees of cooling will help him - but let scorchio try it first and see if we all need it :)
 
Any update?

I just found this site doing research on a possable Prometeia buy. I found this thread and really want to find out what happened with this monster:?

Still in development, I told Phil to take his time with this project as I'm in no rush and I wanted perfection :-)

There have been delays getting some custom parts made in america. Baring any problems this should be finished by end of July. Hopefully we should have some pictures to show you guys soon.

Sorry for the lack of info over the last few months, I've been working at a new job and haven't been at my computer much at all. I'll try and keep everyone up to date as we finsh this monster off though. It's going to be be great!
