Axp-100R ram list?

post #1 of 23
Thread Starter 
Have the 100r on my cpu for a mitx build. Is there a list of which ddr4 kits fit?


Edit I'm asking because I can't find reliable heights on the product pages on newegg, and I don't want to have to keep taking the cooler apart to try different ram

There is no list I know of.

Generally a search for RAM by name with 'tall' or 'height' at end will give results that show ram size.


Distance from top of CPU to bottom of fins plus 5mm it maximum RAM height that will fit.
Top of CPU is 8mm above motherboard
RAM socket raises RAM 3mm above motherboard.
RAM clearance is 5mm plus CPU to fins clearance.

Thank you but I don't follow/math. From the bottom of that cooler to the bottom of the heat sink in ur diagram is 27.15, is that it?

Smallest Ive seen are corsair with 34mm low profile kits, and I really don't want those. I'm looking for aesthetics, but most of the ram I know won't fit because their heatsinks are huge (adata/geil)

Honestly, 34mm tall RAM is not 'low profile' .. except in the mind of those who have only used hi-profile RAM with big heat spreaders that are basically worthless because modern RAM does not generate enough heat to need them.

Normal height RAM is basically normal RAM PCB (printed circuit board) height.

The normal sizes of RAM PCBs (printed circuit boards) are
DDR4 RAM PCBs are 133.35 mm long and 31.25 mm tall
DDR3 RAM PCBs are 133.35 mm long and 30 mm tall.

27mm + 5mm = 32mm
32mm RAM will fit under the fins.

Low profule RAM is like Samsung Green which is 21.4mm tall.
According to Corsair, the Vengeance LPX is 31mm tall

I know how you feel. Trying to find the physical mesurements of RAM is stupid hard. I'ts like trying to find dragon teeth. biggrin.gif
To much marketing hype with names like 'low profile', 'normal height' and 'high profile' .. which mean nothing without a physical measurement .. which they almost never give. mad.gif

sorry this is off-topic, but i'm interested in seeing the rest of your mitx build. i like what i see so far!

Its going very slow since I've been busy with other stuff. It's a secondary pc I'm building for fun

Pretty much just have what you saw + a m2 in the back. No cabling done since I want to order some colored cables

I'm just going off newegg, since I have free 3 day shipping + discounts , they simply have them as desktop memory so can't really find which are actually low profile.

That sucks lol I wanted to get some tridentz, I have the lpx in my atx build and to be honest they're kind of ugly looking.
32mm really limits me.

It does definitely suck. The actual working components are 33mm or less, but the foo-foo /gaa-gaah 'look pretty' "stuff" they add on that is too tall.

Usually if you google the ram you want with "tall' in the search there is the physical size somewhere in results.

In vertically challenged installs, I've used Crucial Ballistics DDR3. The Tactical LP series is 18.75mm tall and the (prettier) Sport VLP is 25.50mm

In their DDR4 range, because it's a new lower voltage package, each stick must be bigger, because bigger is better. The Ballistix Sport LT DDR4 is 33mm. A whopping 2mm higher than the LPX.

Expect as the DDR4 market matures (read: saturates) most 'Consumer' brands will offer breakthrough low profile DDR4. At a huge premium, of course. Because less is more.

Please note: Due to CMC (Consumer Memory Cabal) restrictions, the measurements in this post will self-destruct in 5 minutes. What were once known as physical specifications are now Trade Secrets. Thanks, Consumer Memory Cabal!


Uh-oh...This company is actually publishing physical dimensions of their low profile DDR4 on a public facing website - 18.6mm. Yikes! However, since their target market is commercial, not the Corsair'd consumer realm, they are exempt from the moronic dictates of marketing goofs.

The paranoid among us might suggest the rise of stupid high (and useless) memory heatspreaders from CMCs follows a similar timeline as the rise of Asetek clone CLCs. Probably, just a coincidence. Why would a CMC memory supplier want to sell a product that specifically disadvantages air cooling specialist companies?

So....the RAM will be under the heatsink, so you need shorter RAM. And the RAM will be under heatsink....where it can't be seen. But you are concerned with what the RAM you won't be able to see looks like . Am I following?

Sounds about right. However, you are missing the key assembly stage trauma. One would see those hideous green PCBs while installing the RAM. And in-use, we know those green monsters are hiding under the bed. That can eat away at the mind. And no one wants their mind eaten by green PCBs.

This sort of avoidable distress is why I assemble my systems blind-folded. Sure, cable management isn't ideal, but I sleep better at night ignorant of the shades of green lurking beneath the chrome and glass.
