Where To Buy Ram Board


This board will be a little harder for people who might be newcomers to soldering, not so much because board is pretty much all SMD components, but because the the the SMD resistor arrays are a bit tricky to solder correctly.

I had too much work to do. I needed to get the main floor board up and see what was underneath. I was relieved to find that, for whatever reason, this board and tape came up much better and there were only a couple spots with Tuck Tape residue left behind. Wow, must be my luck day, I thought. But then I stepped back and surveyed the great room. Sonuvabitch.


Upgrading the memory in a computer is usually a straightforward case of swapping out a few DIMMs or SODIMMs, with the most complex task being to identify the correct type of memory from the many available. But sometimes a laptop manufacturer can be particularly annoying, and restrict upgradability by soldering the RAM chips directly to the board. Upgrading memory should then be impossible, but this reckons without the skills of [Greg Davill], who worked through the process on his Dell XPS13.


> restrict upgradability by soldering the RAM chips directly to the boardThe data rates are getting so high that soldered on to the board provides the most reliable and is the cheapest option. The alternative would be to add a 204 pin gold contact SO-DIMM edge connector coated with a thick enough layer of gold plating to last at least the specified minimum 25 mating cycles. That probably adds 5 to 10 bucks to the BOM and it is a through hole part that needs to be hand soldered in place which will probably add another 1 to 2 bucks to the final price. The socket will also uses up a lot of area on the PCB compared to a BGA which adds to the end cost, and requires more traces on the board than a BGA would require. The gold contacts on the SO-DIMM plug needs be thick enough to also last at least the specified 25 mating cycles, and SO-DIMM modules have additional chips to deal with the problems from the edge connector so are not as cheap as a BGA which is additional an cost.


Now that 4x SODIMMs allows for 128GB of RAM, 2x allows for 64GB, which really cuts into the audience for the 4x units; and means that it is almost entirely people who are looking for screaming power across the board.


I stare at a world where your pragmatic sentiment is evacuating the public forums and giving way to the Dunning-Kruger affected, en masse. After all, who has the time anymore to idle on their less accessible tech, the same tech that costs an increasing amount of time to afford?


For sale is the Glitch Works Altair 680 Universal 64K RAM board. This board is a from-scratch new design for the MITS Altair 680 computer, designed and tested with the help of several members of the Altair Computer Club. It has been designed and tested to support front panel operation with the Altair 680, which requires extra circuitry due to the way in which the front panel operates. This board is also compatible with RAMtron/Cypress FM18W08 ferroelectric RAM (FeRAM), a nonvolatile "core on silicon" device.


Circuit boards are high-quality FR4 material, with leaded solder HASL surface finish and true hard gold plating on the edge connector. Measurements for board outline, edge connector, and standoff hole positioning were taken from a number of vintage MITS boards and averaged out. The mechanical dimensions of this board are the same as our GW-A680-1 prototyping board.


This project is available as a bare circuit board, board + parts kit, or fully assembled and tested. Assembled and tested boards are burned in on an original Altair 680 using Martin Eberhard's excellent memory test program.


Do note that, while the board supports a full 64K of RAM, there are special considerations for the top 8K of RAM. Enabling the 60-64K bank will conflict with the ROMs and ACIA serial port on the 680's' motherboard. Enabling the 56-60K segment will not cause conflicts, but will cause MITS BASIC to lock up since it hits the ACIA during memory sizing and stops console response. We currently recommend enabling only 0-56K for 56K of total memory.


The wider spacing of the components on the printed circuit boards that make up desktop DIMMs allows for additional parts to be installed, such as heat sinks and or even RGB lighting strips for PC modders. Laptop-style SO-DIMMs, on the other hand, are designed to be installed in tight, stacked or overlapping slots, and to be invisible, and thus skip such excess. A pair of each is shown above.


Thus, the fastest practical kits for most performance enthusiasts will contain (and we'll emphasize this with boldface!) dual-rank modules rated at DDR4-3600 CAS 14. (That is, unless you can find these specs at something lower than CAS 14.) Compatible platforms include recent mainstream AMD AM4 boards, along with most Threadripper (sTR4), Intel Core-X (LGA2066, LGA-2011v3), and mainstream Intel (LGA1200, and LGA1151), assuming the board is equipped with overclocking features.


As with the Z590, it might be necessary to increase the power threshold of lower-energy (65-watt) processors to prevent a power-throttling increase. Check your motherboard firmware for these settings prior to memory selection.


Remember that Threadripper X399 boards tend to have eight memory slots. Breaking from DDR4-3600 recommendations because many builders wish to fully populate these boards with eight dual rank modules (16 total ranks), stability at this setting is still common when using up to eight total ranks with the Ryzen Threadripper 2950X. Earlier processors can be fussier, though. DDR4-3200 is compatible across most Threadripper processor models and memory configurations, but AMD recommends only DDR4-2933 for second-gen Ryzen Threadrippers and DDR4-2666 for first-gen Ryzen Threadrippers.


DDR3 is the sign of a geriatric PC, and spending to the max on performance-minded RAM for a platform that is fast disappearing in the rearview mirror may be false economy. Most DDR3 motherboards supported at least DDR3-1600, with later examples such as the AMD 990FX and Intel Z97 often exceeding DDR3-2133 and DDR3-2800, respectively.


This card is a great solution for older XT machines which are not capable of 640k memory on the motherboard. The original architecture of the IBM XT has 20 address lines which gives a maximum memory space of 1MB. The top 384k is typically reserved for BIOS, leaving the lower 640k available for applications. This board will address the full 1MB address space, and some machines and applications will allow access to the upper memory area. This card has 16 dip switches to allow access to memory in 64k sections, so you can enable and disable ranges as you like. Additionally, you can set the card to allow access above 16k for the original IBM 5150.


Please be aware this card is 8-bit, and not meant for 80286 or greater machines. It is possible it may work in later systems to a degree, but it would cripple performance as the data bus is limited to 8 bits. If your IBM XT or clone already has 640k of RAM, then you do not need this board. If you can upgrade your motherboard to 640k, we recommend that approach instead. It is meant for systems which have a limitation on how much RAM can fit on the motherboard. Many of the original IBM XTs are limited to 64k or 256k on the motherboard making a RAM expansion board essential.


This card does not have a mounting tab, so please be careful to orient the card the proper direction in the system. Plugging a card in backwards could damage the card, or your PC. We test all our assembled boards, but we do not guarantee compatibility nor are we responsible for any damage to your equipment. Please treat this board, and your PC with as static-sensitive, and never install cards while the power is on. We test all of our preassembled boards, so there may be a little wear on the teeth. Non-assembled PCBs will not have this wear.

I have recently chickened out of cloning my SSD and transferring the files to a new SSD. I took it to my local computer store and had them do it. Meanwhile, upon asking questions about upgrading to Windows 11. I learned that my current board and CPU and possibly my RAM will not support it. I know nothing about looking for a new board, CPU and or RAM.


Initial searches for data on your motherboard suggest that it will support Windows 11 64 bit, but for a definite determination of how well supported your setup will be, we need to know exactly which AMD Ryzen CPU you have installed on the board, and how much of what kind of memory (RAM) you have installed on the board as well.


I do not know why I was told that my current motherboard and CPU were not capable. I assume that my previous SSD was too small to run Windows 11. Not that I am in any hurry mind you. I just want to be ready when the time comes. I am however thinking of upgrading my RAM. Is that very easy to do?


FYI: if you have four RAM slots on your motherboard, they are usually color coded, so that you can insert pairs corresponding to the correct channels, i.e., DIMM_A1 + DIMM_B1, and/or DIMM_A2 + DIMM_B2.


Nice benchmark! An example would be if you bought RAM that was labeled as DDR4-2600, where an individual stick runs at 1300MHz per channel. You only achieve the full 2600MHz bandwidth if you use 2x memory sticks at 1300MHz each, in dual channel mode! You cannot get that full memory performance using only one slot!


That information is incorrect. DRAM speed also depends on what the motherboard will support and enabled in UEFI. One stick of DDR4-2600 will run at 2600MHz if the motherboard supports it and the setting is enabled. Two sticks of supported DDR4-2600 will run at 2600MHz. Three sticks of supported DDR4-2600 will run at 2600MHz. Four sticks of supported DDR4-2600 will run at 2600MHz. 041b061a72
