VRAM heatsinks

[Lays]

Does anyone have any recommendations for VRAM heatsinks for my card?  I'll need 12 of them.

I heard some are really hard to remove, I'd like to easily be able to remove them, but I don't want them to just fall off randomly. 

Also my card sits in a testbench, if that matters at all for whether I need stronger adhesive or something.

 

This is what I mean btw:

 

 

I'll be putting my universal waterblock on this week, I doubt I'll need the heatsinks, but I may get them anyways.  My card doesn't have active VRAM cooling, they are cooled by the air that comes through the heatsink, so when I take the heatsink off they won't have that airflow anymore.

 

They only hit 65c max with a measly ~40% fan speed after folding for nearly 10 hours so it shouldn't even be an issue if I just point a fan at the card, but they seem cheap so I may just buy a set for the hell of it.

 

Here's a picture I took to show temps of VRAM & VRM after 10 hours of folding at ~40% fan speed

 

 

I won't need VRM heatsinks since my card has a VRM heatsink that's separate from the cooler.

Pointless since the heatsink doesn't feature VRAM cooling in it's design

btw, don't overvolt your memory like that >.>

It's not overvolted, ~1.6-1.64v is stock voltage for memory on 980/970/980 ti/titan x.

Still seems high. Most cards use 1.5

[TheGamingBarrel]

really? Do you have experience with lots of GPU's and reading voltage with digital multimeter?

You must have not much experience with cards then, 970,980,980 ti, titan X all have 1.6v memory voltage stock.

 

680 Classified has 1.6v stock, 780 & 780 TI & 770 are all 1.6v as well.

AMD cards tend to be at 1.4-1.5. Odd

not odd at all, nvidia cards tend to have higher memory frequencies.

[don_svetlio]

1500Mhz at 1.5 on the 280X.

[Lays]

1500Mhz at 1.5 on the 280X.

 

 

That's only 6000 mhz effective, most nvidia cards right now are running 7000 mhz effective, some are at 7200 on aftermarket designs.

6700 was 6000MHz effective at 1.6?

[harrynowl]

6700 was 6000MHz effective at 1.6?

AMD 1.5v -> 6000MHz effective

 

Nvidia ~1.65V -> 7000MHz+ effective

[don_svetlio]

AMD 1.5v -> 6000MHz effective

 

Nvidia ~1.65V -> 7000MHz+ effective

670 was 6000MHz IIRC as the 7950 was 5000MHz back then

[Jumper118]

Yes a full cover block is a great vrm heatsink.

[TheGamingBarrel]

Almost a 100% clock speed improvement on darrens old card, almost 9300 effective.

Btw, almost every cooler design from the 950 up has integrated vram cooling, whether it be via a front plate on evga cards or being directly integrated into the cooler like gigabyte or asus cards. To say that his top of the line overclocking card doesnt account for cooling the vram is idiotic.

Asus have never and will never cool VRAM.

[Lays]

They clearly do, airflow from the heatsink cools it, and obviously cools it perfectly fine as with 40% fan speed and 10 hours of folding, the memory is only hitting 65c.

I meant with a separate heatsink or direct contact plate like the ones EVGA and Sapphire use
