Watercooled my 7800GT, hot memory though!

I've stuck a DD Maze4 Low Profile block onto my BFG7800GT along with some ramsinks on the memory, I can't believe how much quieter it is :D
Temps are nice and low with the core not getting above 35 degrees under load but i've noticed the memory on the card is getting REALLY hot.

I had the card overclocked to 500MHz core and 1200MHz memory but after an hours gaming I started getting graphics corruption so had a quick poke around the card with my finger and found the memory was burning hot. I've dropped the memory speed down to stock and I'm not getting corruption anymore but I can't help feeling that with more airflow over the card (kinda against this as that was the point of water cooling in the first place) or with a larget block like the DD NV78 I could whack the speed back up again.

Anyone else experienced high memory temperatures? What did you do?
 
if Nvidia/Ati make stock coolers that cover the memory and keep it cool, i think that means its designed to be cooled.

This applies to ATi more than Nvidia, as now with ATi all the memory is on the front of the cards.
 
I really thought it doesn't kick out much heat. You just wait, you'll have about 6 guys jump in and say "It shouldn't be hot, I run mine oc'd and with no sinks". Mine doesn't get hot on my card :\ So either something weird's going on with your card, or people are wrong :S
 
why would ATI/NVIDIA and countless watercooling companies make full cover cooling solutions if it wasnt designed to be cooled?

Surely its common sense.

Even a zalman cooler that doesnt cool the ram, comes with ramsinks

I know, I know, but many people state that their RAM is left alone and it's fine. AS I've said, mine doesn't get hot either. And btw, Nvidia/Ati's HSF design is NOT all knowing. Why pull air from the rear of the case and chuck it straight back out into the case :\. I though at first it could be something to do with Arctic having a patent on the DHE system, but ATI are doing it now so that rules it out. This suggests that the designs alone aren't proof that they know what they're doing when it comes to cooling.
 
I'm of an opinion the same as welshtom at the moment, if its cooled by the stock cooler then it needs to be cooled. Unfortunately I don't have the space in my case to get a 120mm fan below it (too many PC cards and a pump in the way) but i'm thinking i might be able to fit a 80mm fan perpendicular to the card blowing accross it. Though i'm tempted to get a block that covers the memory as well when i have some money...
 
well, they prob know more than us :)

my x1900xt has ramsinks on it and they are warm to touch when im playing games. and thats with good airflow.
 
The reference designs are pretty poor. My 7800GT blow's air towards my HDD's and against the intake fans, not good. Just as well the Fusion is going on soon, with no ramsinks I might hasten to add. :p

So you all agree that Nvidia's design is the be all and end all of cooling theory?

Not at all but if you were nvidia would you bother spending extra cash on a cooler that covers the memory as well if it wasnt needed? Granted it probably doesnt cost them much extra but its still money that could have gone to pure profit if it wasnt needed ;)

Keep us posted on how hot your memory gets :)
