DDR3 SO-DIMM sticks with thermal monitoring

Hi, I'm looking for some 8GB 1333mhz+ SO-DIMM sticks that have temperature monitors on them, if anyone knows of any, please share

 

Never heard of such configurations of RAM.

 

I have it's called gimmick that is for looks and doesn't function.

 

It's up to the motherboard as far as I know. On my DC 8740w there are thermal sensors, on my nonDC 8740w there aren't. Both are quad-core with 4 RAM slots, so I guess there's variation between quad boards as well (there are dual core (the only difference is the lack of two RAM slots, they still support quads) and quad core boards).

 

Let me try this again. Idk how it's a gimmick or just for looks, but being able to monitor internal ram temperatures would be kinda nice. If you ever looked at some of these Micron sticks, they have On Stick Thermal monitoring, I have a 4GB stick right here, 16JSF51264HZ-1G4D1

Right from my data sheet

• On-board I2C temperature sensor with integrated serial presence-detect (SPD) EEPROM

It has an SMBus address and everything, I can read it with HWinfo

 

Where the link?

 

I figured you could Google the part number

OK, let me try again as well - with the same modules it was showing readings on one machine and not on the other.

 

Are you sure it's not the possibility your motherboard haz a thermal zone? Do your sticks actually have thermal sensors integrated into the SPD EEPROM? I have taken this one stick and every single laptop, mini it motherboard it has been put in, every single one has shown it as a sensor, My HP Touch smart 15, my D900F, My GT660, my friends GE70, My other friends GS70, my awful HP G72, even the boot camped MacBooks lying around, my H81T board, my Sony Vaio VPCF-1, And I assume any other machine it's put in.(I cannot be sure, I haven't tested every machine ever) It registers as a sensor via the I2C bus which every single machine that has SPD on the ram slots has, because it is required to in order to be JEDEC compliant.

What sticks do you have?

I'm asking if anyone knows a model of an 8GB stick of RAM with a Thermal Sensor on the EEPROM. That was all.

 

By schematics my MoBo has to has a single thermal sensor and it is missing (not soldered). Anyway, it shows the readings of all 4 - 2 are Micron 4GB (each), came with the system, the other 2 are crucial Ballistix Sport 1600MHz 8GB (each).

 

Odd. I don't get why it wouldn't work on some boards unless it doesn't pass data to the Bus?

Anyways, I am looking for 8GB sticks if possible, I have 4GB sticks with monitoring, I'd like 8 if possible?

 

The Ballistix are 8GB (16GB kit). It's odd indeed, especially on what's supposed to be the same boards.

 

Problem is the thermal monitor is not on-die. It's an external temperature sensor connected the the SMBUS and place somewhere on the DIMM PCB at a location that hopefully has some semblance to the overall ambient temp of the module. The second problem is you need an app that is aware or can find the sensor. HWINFO does a good job and there are several others. It's not a gimmick, there are genuine use cases in industrial and server apps but in a home environment it really isn't a problem unless your cooling is cr@p!

 

I'd encourage you to check out the D900F heatsink positions... With the ram under the huge heatsink, I want to monitor ambient temperatures(also adding a small metal plate to act as ram heatsinks would provide a reading more reliable but seeing area temperature is useful to me)

 

if you want to monitor something in your motherboard then use an usb thermometer. you can connected via an usb to mini pci-e adapter. you can also add cables. it's cheap and effective and doesn't ruin the battery or it's dangerous. just make sure you don't make any short circuit and isolate the wires and pcb with exception of the probe itself. that's the best way.

as for metal plates there's copper heat sinks for sodimm ram. I used it. there's copper and aluminium. obviously copper is better. but the mobo has to have room for it. sometimes you can only add it to 1 side.

 

While I greatly would prefer a more compact solution, that is amazing!!! I have an unused mPCI-e I was gonna put a microsd in but seeing that is awesome. Does it show up as an SMBus device that I could add to my RTSS display via HWinfo? Also, can I monitor 3 sticks? And last would be, do you have links. That's the best usr for this Robson port I've seen yet! Flash Cache was dumb lol. Thank-you for your help!

 

the ram heatspreaders, it's sunbeamtech NMHS-C. but imo it's just a sheet of copper with that cut out. you would have similar results with a rectangle copper sheet of the similar size. there's aluminium version, obviously copper is a better heat conductor.

the usb thermometer I just have 1 stick. they are cheap. I bought it for 5€ to work as a remote weather station (among other sensors). if you can monitor 3 sticks? you can monitor 3333333 if you want. it's usb. if it works with SMBus? depends on the model. some do (if not all)
some have a prove some don't. you obviously have to disassembly the thermometer out of the enclosure to make room so it can fit inside the notebook. unless you make it work by using an usb cable. if you have and don't mind removing the optical drive or 2.5 HDD it will give you a great room for mods, you can even add an usb hub and make more ports if you cut the case. or even leave it as it is inside the 2.5 bay and add your mods. it's usb it has no limits. gps, 4g modem, tv reciever, sdr, anything really.

you have tons of others on ebay and similar

for the mini pci-e. it's tricky if you want usb3.0 cause those are hard to find and needs to have drivers for your OS. for usb2.0 anything works. there's several sizes. the one I saw can be cut down into half mini pci-e which is great to save space. but there's others full size with 2 ports

a tip, if you want an usb hub, get one of those octopus or squid type. they have separate usb cables connected to a very small pcb hub. it may be a lot easier if you want to mod things. looks big and bulky but pcb inside is really small.

also don't forget to shield everything. don't just have the pcbs on top of the motherboard. if they touch in the wrong spots you may fry your notebook. just isolate everything. kapton tape or electrical tape. it does the job
