Skyrocketing memory prices may get worse before getting better

ram install 10 of 11

The price of desktop RAM keeps on going up, and the disappointing trend is expect to continue for a good chunk of 2017.

Right now, the best price you’re going to find for 2 x 8GB desktop DDR4 RAM modules on Newegg is about $73. But if you want something from a larger brand like G.Skill or Corsair, expect to pay more—those 16GB kits are frequently selling for more than $100.

The price increases began around mid-2016, as Newegg Business noted in a blog post in August. PCPartPicker’s memory price trend page indeed shows the cost of all types of RAM surging upward since May or so. The reason at the time was that the big money was in producing DRAM for mobile devices, followed by servers, and then finally desktops.

Since then not much has changed, with mobile device production being so big the demand is outstripping supply. At least that’s the word from DigiTimes. The newspaper spoke with Pei-Ing Lee, president of Nanya Technology, a RAM manufacturer based in Taiwan. Lee told DigiTimes that global RAM supply is still falling just short of demand—a situation Lee doesn’t expect to see improve in the spring.

By the third quarter (July through September) prices could stabilize, according to Lee. But all that really means is the price will stop going up.

Lee’s view is, of course, only one opinion, but it’s a well informed one, and corresponds to overall trends in RAM pricing. As PC Gamer points out, pricing is seriously rising. A 2 x 8GB kit of G.Skill DDR4-2400 RAM was priced around $75 at Newegg in late November (the cheapest vendor at the time), but that RAM is now hitting $92 at the same outlet, according to PC Part Picker’s pricing history. In mid-December you could’ve picked-up Patriot Viper Elite 2 x 8GB DDR4-2133 RAM for $80, but today that kit would set you back at least $100.

The impact on you at home: If you need to buy RAM for a new system, it appears there’s no real reason to wait as you’ll be paying extra now and possibily paying even more in the coming weeks. Anyone planning a rebuild later in 2017, however, might want to buy their RAM now, as reusing your DDR3 from an older PC may not work.

With the switch to Intel’s Skylake and Kaby Lake processors, modern systems require the newer DDR4 RAM or low-voltage DDR3L memory. On the AMD side, the DDR4-supporting Ryzen is rolling out in the coming weeks.

Computer scientists in Singapore and Germany have collaborated to create a resistive RAM chip that not only stores data but can act as a computer processor.

The breakthrough uses state-of-the-art memory chips known as Redox-based, resistive switching random access memory (ReRAM) and could lead to much faster and thinner mobile devices. Today’s computers must transfer data from the memory storage to the processor unit for computation, which along with slowing performance also requires more power.

“This is like having a long conversation with someone through a tiny translator, which is a time-consuming and effort-intensive process,” said Anupam Chattopadhyay, an assistant professor at Nanyang Technological University (NTU) in Singapore. “We are now able to increase the capacity of the translator, so it can process data more efficiently.”

While the new circuit saves time and energy by eliminating data transfers between disparate storage and processors, it can also boost the speed of  processors found in laptops and mobile devices by at least two times or more, the researchers said.

By making the memory chip perform computing tasks, space can be saved by eliminating the processor, leading to thinner, smaller and lighter electronics. The discovery could also lead to new design possibilities for consumer electronics and wearable technology, the researcher said.

NTU researchers worked with others from Germany’s RWTH Aachen University and Forschungszentrum Juelich to create the new memory chips. Their research was published in the peer reviewed journal Scientific Reports.

Also known as memristor, the ReRAM came from global chipmakers such as SanDisk and Panasonic. ReRAM chips are one of the fastest memories on the market and are already commercially available for IoT applications. In 2015, Hewlett-Packard and SanDisk also announced an agreement to jointly develop “Storage Class Memory” (SCM) ReRAM that could replace DRAM and would be 1,000 times faster than NAND flash.

Until memristor, researchers knew of only three basic circuit elements—the resistor, the capacitor and the inductor. Memristor added a fourth, which consumed far less energy than previous technologies.

While ReRAM has been under development for many years as a storage technology, NTU’s Chattopadhyay, in collaboration with Professor Rainer Waser from RWTH Aachen University and Vikas Rana from Forschungszentrum Juelich, demonstrated for the first time how it could also process data.

“The quest for faster processing is one of the most pressing needs for industries worldwide, as computer software is getting increasingly complex while data centers have to deal with more information than ever,” the researchers stated in a news release.

How the ReRAM works

Computer processors today use the binary system where bits of data are represented as either a 0 or a 1. For example, the letter A will be processed and stored as 01000001, an 8-bit character.

However, the prototype ReRAM circuit built by Chattopadhyay and the other researchers processes data in three states instead of two. For example, it can store and process data as 0, 1 or 2, known as the Ternary number system.

“Because ReRAM uses different electrical resistance to store information, it could be possible to store the data in an even higher number of states, hence speeding up computing tasks beyond current limitations,” the researchers stated.

The researchers plan to develop the ReRAM to process more than its current three states, which will lead to even greater improvements of computing speeds.

Using ReRAM for computing will be more cost-effective than other bleeding-edge computing technologies on the horizon, since ReRAMs will be available in the market soon.

“Using them not only for data storage but also for computation could open a completely new route towards an effective use of energy in the information technology,” Waser stated.

Your walk may predict decline in memory, thinking

Individuals who suffer problems associated with walking such as reduced speed, imbalance, among others, can be at an significant risk of developing decline in memory and thinking, a study has found.

Walking is part of the complex cognitive task known as gait that includes everything from a person’s stride length to the accompanying swing of each arm.

Previous studies have reported that slower gait speed might predict cognitive impairment and dementing illnesses, supporting the role of gait speed as a possible subclinical marker of cognitive impairment.

In the study, researchers from Mayo Clinic in Minnesota, US, used a non-invasive computerised gait analysis test that could identify patients at high risk for cognitive decline and to target appropriate therapies.

They measured gait parameters, such as stride length, ambulatory time, gait speed, step count, cadence, stance time, arm swing on each patients.

The results showed that alterations in several of the gait parameters were associated with decline in memory, thinking and language skills, and visual perception of the spatial relationship of objects.

“The presence of gait disturbances increases with advancing age and affects the independence of daily living, especially in the elderly,” said lead author Rodolfo Savica, neurologist at Mayo Clinic.

For the study, the researchers analysed 3,426 cognitively normal participants who were between ages 70 to 89.

The study was published in the Journal of Alzheimer’s Disease.

Aerobic Exercise May Ward Off Memory Decline In Elderly

Aerobic Exercise May Ward Off Memory Decline In Elderly

erobic exercise (also known as cardio) is physical exercise of low to high intensity that depends primarily on the aerobic energy-generating process.

The study by researchers at the University of British Columbia in Vancouver, Canada, showed that those who exercised had a small improvement on the test of overall thinking skills compared to those who did not exercise.

In addition, those who exercised also showed improvement in their blood pressure levels. High levels of hypertension may increase the risk of developing vascular cognitive impairment — the second most common cause of dementia after Alzheimer’s disease, the researchers said.

In vascular cognitive impairment, problems with memory and thinking skills result from damage to large and small blood vessels in the brain.
“Studies have shown that exercise can help reduce the risk of developing memory problems, but few studies have looked at whether it can help people who already have these problems get better or keep from getting worse,” said Teresa Liu-Ambrose from the University of British Columbia.

For the study, the team involved 70 persons with an average age of about 74 who had mild vascular cognitive impairment.

The scores of those who exercised improved by 1.7 points compared to those who did not exercise.

Vitamins A, C Help Erase 'Memory' In Stem Cells: Study

Vitamins A, C can enhance success in the challenging process of converting adult cells into stem cells

MELBOURNE:  Vitamins A and C complement each other in erasing “memory” associated with DNA, an important effect for improving technologies geared towards regenerative medicine and stem cell therapy, scientists have found.

The two vitamins can enhance success in the challenging process of converting adult cells into stem cells, an international team including researchers from University of Otago in New Zealand have found.

Ordinary adult cells, such as those in the skin or blood, can be artificially coerced in a culture dish to resemble embryos only a few days old.

Since the 2006 discovery that this remarkable reprogramming process is possible, there has been much interest in using induced embryonic stem cells to cure human disease, said Tim Hore from Otago.

“However, hampering these efforts is the reality that adult cells are resistant to changes in their identity, partly because of chemical alterations to their DNA,” said Hore, who was previously with the Babraham Institute in the UK.

He said these alterations, known as “DNA methylation” are acquired during development and provide a form of cellular memory that helps cells faithfully maintain a specialised function.

Removal of this memory is critical in order to create a developmentally potent stem cell, or to change one kind of adult cell to another.Hore determined that adding vitamins A and C to culture dishes synergistically removes DNA methylation from embryonic stem cells.

When applied to cells during the reprogramming process, those with the desired “naive” embryonic characteristics were created in much greater numbers, he said.

“We found that both vitamins affect the same family of enzymes which actively remove DNA methylation; it turns out that vitamin A increases the number of these enzymes within the cell, and vitamin C enhances their activity,” he said.

In addition to regenerative medicine, this work may have implications for other areas of biomedical importance. Loss of DNA methylation and cellular memory are a hallmark of certain cancers, so a better understanding of how this process occurs could prove significant.

“We are beginning to explore how the vitamin-induced effects we have uncovered in this study might impact on the loss of DNA methylation in certain cancers,” he said.

The study appears in the journal Proceedings of the National Academy of Science (PNAS)

Memory Loss Not Only Indication In Alzheimer’s Diagnosis

Memory Loss Not Only Indication In Alzheimer's Diagnosis

Researchers should not rely on the clinical symptoms of memory loss alone to diagnose Alzheimer’s disease because there could be other indicants of the neurodegenerative disease that do not initially affect memory, says a new study.

There are more than just one symptom of Alzheimer’s disease. These could be language problems, disruptive individual behaviour and personality disorder — even judgement of someone’s concept of the position of objects in space, said researchers at Northwestern University, in Evanston, of Illinois, in the US.

If it affects personality, it may cause lack of inhibition. For example, someone who was shy might one day go up to the grocery store clerk — who is a complete stranger — and try to hug or even kiss her.

This all depends on what part of the brain is affected by Alzheimer’s, the study said.

However, “these individuals are often overlooked in clinical trial designs and thus miss out on opportunities to participate in the experiments formulated to treat Alzheimer’s”, said lead author and Associate Professor Emily Rogalski at Northwestern University.

“Such individuals are often excluded because they don’t show memory deficits, inspite of sharing the same disease (Alzheimer’s) that’s causing their symptoms,” Rogalski added.
In the study, the authors identified the clinical features of individuals with primary progressive aphasia (PPA) — a rare dementia that causes progressive declines in language abilities due to Alzheimer’s disease.

During the initial phase of PPA, memory and other thinking abilities are relatively intact. Also, PPA can be caused either by Alzheimer’s disease or another neurodegenerative disease family called Frontotemporal lobar degeneration (FTLD).

The study demonstrated that knowing an individual’s clinical symptoms was not enough to determine whether PPA was due to Alzheimer’s or any other neurodegenerative disease — where progressive loss of structure or function of neurons, including death of neurons happen.

Therefore, an amyloid positron emission tomography (PET) scan — an imaging test — should be taken.

PET scan tracks the presence of amyloid — an abnormal protein whose accumulation in the brain is a hallmark of Alzheimer’s.

PET scan should be used in early life to determine the likelihood of Alzheimer’s disease pathology in later life, the researchers said in the study published online in the journal Neurology.
