the duality of RAM

     I feel like installing more RAM on my computer, for gaming and 3-d stuff. But I can't decide if I want 1024 mbs on a single stick, or two sticks with 512 mbs each.            Also, it would be nice two have 2 gbs instead of 1, but I've heard horror stories about instability. please discuss this as well.            Money isn't an issue (well, maybe.) I just want what will work best.       And please don't be afraid to go geek on me. thanks as always.

External RAM

I was thinking today about possible ways to make my pc better without adding internals. (I like external plug and play stuff). So anyway, I was thinking about my RAM and how to make it better. Then it hit me. What if I had external RAM? Possibly using 2 or more USB ports. Any Ideas? This would allow me to run large programs on any PC! Please collaborate.

Reusing RAM memory?

Hi everybody. I'm looking on the web if there is a way to reuse my old Ram memory. And I don't find anything.... As you know, each time we change for a new computer, we have to change the Ram to match the CPU and motherboard. And I'm stuck with a lot of useless Ram, life warranted for most :) So is it possible, to reuse the chips or add usb plug or something to use it as a external usb key? I'm understand, it could be not easy but ... I 'm curious. :) Thank you.

iMac Ram maximum? Answered

This is an interesting question about my mac (its a MA710LL).  Currently, I have 2 and 1/2 gigs of ram in it, but supposedly this model can only handle 2 gigs.  It has the appearance that it is only using 2 of the 2 1/2 gigs, and that it can "sense" that there is some more, but is there a way to make it use the other 1/2?  Thanks in advance.

Dual-Channel RAM? Answered

I have a Gigabyte GA-H55M-USB3 Motherboard and an i5-760 CPU. I have been using 4x1GB DDR3-10600 modules, and then recently bought 2x4GB DDR3-10600 modules hoping to get 10GB, however, I can't seem to get it to work. All the modules are in working order and work individually. I currently just have a single 4GB module in. If I insert more, I either get a constant bios speaker tone indicating RAM error, or it will post successfully, but Windows will bluescreen. I have looked in the booklet and it is unclear as to how I should install the modules, but I thought I had to install them in matched pairs corresponding to the coloured slots on the motherboard. I have tried the 4GB modules in the white slots and the 1GB modules in the blue slots, but it won't post. Putting the two 4GB modules in a white and blue slot will post fine, but BSOD on startup. Any idea how I can get this configuration to work with my board? My CPU and board both support dual-channel DDR3 memory, so I can't see the problem here.

Rcan someone help me choose my RAM ? Answered

Hy everyone! i'm currently buying my parts for my new computer and need help to choose my RAM. I have two final choices: they each have these specs in common: 32Gb ( 4x8Gb ) DDR3 unbuffered but differ by the frequency they have and the price. freq and prices: PC3-14900  1866MHz  for 565 euros and PC3-12800  1600Mhz  for 315 euros My build is quite high end and my mobo chipset is an X79 from intel. both of the ram above are from Corsair. I intend to mostly do gaming, 3d( with solid works- like programs) , video recording(for games) and video editing , and programing. memory id is CMT32GX3M4X1866C9 for the higest priced and                  CMP32GX3M4X1600C10 for the other one. Thanks for your responses. PS: my mobo specs tell me that it only accepts PC19200/17000/16000/15000/12800/10600 memory. Is PC14900 the same as PC 15000 or is it different? Thanks again everyone!

Question by didgitalpunk   |  last reply


I can use very little of my computer's ram

I have recently bought an expensive new ram card for my laptop. I bought it to add to what was on my laptop. But, I can only use the second card (since my laptop has two ram slots), even though the computer has recognized the new card, it won't let me use it. Here's what it says in system properties: Installed memory (RAM): 10.0 GB (1.74 GB usable) I just can't figure it out. I even looked to see if my computer had set a limit by going to the start menu, typing 'msconfig' and seeing if any limits were set, and I could not see any. UPDATE: I believe I need to check one of the ram slots because I switched the slots that the cards were in today and when I turned the computer back on the new ram card was able to be used but the old, smaller one was not. I think it is just needing to be cleaned/inspected. If that is the case, this question will be deleted. If not I will update it again if a new problem arises. Thanks for your help!

Question by eaquino   |  last reply


computer RAM upgrade stupid questions?

Well as it turns out, 8GB of RAM with Chrome and Kdenlive video editing software open at the same time causes Ubuntu to max out the RAM on my machine, and the machine will start to become very sluggish, eventually freezing for several minutes at a time with a high chance of never unfreezing. This used to be a very common issue that would occur with only google chrome open, due to a memory leak with my Gmail tabs. If I catch this sluggishness and eventually full system hang early enough, I can recover from it by entering CLI mode on ubuntu (alt+F1) and killing "chrome." After researching this problem a bit more, I created a swap file, since I do not have a SWAP partition, this helped delay the eventual unrecoverable system hang, but did not entirely fix the issue. I also tried different "swappiness" values, and also learned about this command "sudo sysctl -w vm.min_free_kbytes=400000" which supposedly forces a set amount of space to be unused in ubuntu. Looking at the system monitor this appears to do what it says, preventing a >95% RAM use, forcing swap to be used instead, and this was initially promising as it seemed to reduce the full system hangs, but created more small bugs, like freezing and stuttering wildly with buffered youtube videos, or playback in Kdenlive. A reboot seemed to have fixed that issue, but I'm not sure if those settings stuck around. ANYWAY; I guess there is no denying it, I simply do not have the RAM necessary for my workload anymore. I DO use intel HD integrated graphics, which uses the system RAM for graphics processing, so I wonder, will faster RAM allow slightly better graphics performance? My understanding is that GDDR is optimized for sheer bandwidth, not latency, while system DDRx RAM is optimized for latency. Does this mean my system will benefit more from high clock rate and high latency setting on a given RAM set, or is low clock and low latency RAM better? Most "gaming" orented builders seem to say RAM is not important other than esthetics and reliability. Also, is there a difference between buffered and unbuffered RAM?  Currently, the specs for my RAM are: Geil EVO Veloce GEV38GB1600C9DC 4GBx2 This RAM I got for "free" with my motherboard, and it seems to work with the following settings in the BIOS: . . .1600MHz @ 9-9-9-28 timings, 1.5V . . .1333MHz @ 9-9-9-24 timings, 1.5V . . .1800MHz @ 11-12-11-33 timings, 1.65V These are the fastest possible settings that will boot. Note, I was not too happy with the 1800MHz overclock, especially considering my computer was acting strange and crashed during an update, corrupting Ubuntu. I was able to repair the installation of some corrupted packages halfway installed. It did not seem to make any difference in some games on ubuntu, which is how I tested stability/speed. I have also had issues where while the BIOS system check passes, ubuntu puck errors all over me when I clocked at 1600MHz @ 9-9-9-24, even at 1.65V. There is really no overclocking this currently overpriced and mediocre RAM to any degree. The three settings above were the best settings I could get. The RAM I am currently looking at getting is: http://www.amazon.com/Crucial-Ballistix-PC3-12800-240-Pin-BLS2K4G3D169DS1J/dp/B00ZRG009S/ref=sr_1_1?s=pc&ie;=UTF8&qid;=1452056996&sr;=1-1&keywords;=BLS2K4G3D169DS1J It is the most affordable, and states that it is 4GBx2 of 1600MHz 9-9-9-24 RAM. I think I can underclock it to match the speed of the rest of my RAM and I think it should work well alongside. What do you guys think? I do not want to have to buy the $67 16GB if I can help it.

RAM error cause / fix

I've started getting system service exceptions, and have linked the cause to the RAM, which has shown around 10 errors when tested, mainly that certain pairs do not store data accurately, on at least one of the sticks. I need to ascertain the cause of these errors to see if the warranty covers it. Would it be possible to get or write a program to keep writing to the defective locations, to prevent important applications using the space?

What are the specs on this ancient RAM?

 I would like to replace the two 64 MB modules in an ancient computer with two 256MB modules. Unfortunately, Linux was unable to report a manufacturer or model for the motherboard (only that it has a 950Mhz Duron and mostly SiS onboard components.) Even that report is suspect, as it said there are four memory slots when in fact there are two. So, take a look at this photo of three sticks of memory which worked successfully in the machine. What exactly are their specifications? Then, look at the specifications in this Ebay ad.  Is it fully compatible (assuming the computer can handle 512MB)? Update: Apparently the seller who I originally linked to is a scammer. I'll reference a more legit looking Ebay seller instead.

How much RAM is on a stick?

I bought a $20 computer from the Salvation Army, and it is in working condition. However, I dont have a spare mouse, monitor, keyboard, or power cord for it. So I did like a normal nerd, and harvested it. I got all the internals(It was running a Pentium II on windows 98, so it's pretty old) including the RAM. It had 3 sticks-1 SIMM and 2 DIMMs. On the SIMM, it clealy said that it had 64MB. However, on the other two, it says nothing about size from what I can see. There is a label, if it means something, that says: MT16LSDT464AG-662C1      9807D      308210                      5000227 On the first label, and: MT16LSDT464AG-662C1 9808D 30821C                     5000227 On the second. I would really like to know how much is on these sticks, so I know if I should use them for myself, sell them, or just trash them. Thank you!

Laptop charges only tipped on side?

Greetings!  I'm in need of some laptop power help. About ten days ago, my 1-year-old HP Pavilion G7-2017 laptop stopped charging when plugged to the AC adapter.  I've googled this issue a bunch and have only come up with wobbly power seats, battery issues, or with people who have finicky adapters that have to be moved to get a charge.  None of these are applicable to my situation.   Currently, my laptop (not the charger) has to be moved or tipped to get a charge from the old AC adapter but runs great on battery power once charged and, if stood on its side, will connect to the power supply without the battery installed.  Moving the laptop breaks the power connection, though, and shuts the computer down if the battery is not in it. In fussing with it, I discovered it would work when either: A) it was tilted totally on its left side (dc connector is on the right side, so cord would then stick out the 'top') B) slight pressure was put on the underside just in front of the battery where the RAM is located.  Finally, it stopped registering the AC adapter with either the orange or white LED and I couldn't get it charged so I did the next logical thing and took the whole thing apart.  I thought because of the nature of how it was charging and finicky it might be a loose connection to the power supply internally.  I took everything in the laptop out and double checked all the connections on power, motherboard, etc -- nothing is amiss.  The power cord slot inside is secure and functioning, RAM is seated correctly, etc.   Put it all back together and still couldn't get it to charge so I took it to Best Buy to borrow an appropriate AC Adapter today.  This is what happened: 1.  With the battery in, I plugged in new power cord while laptop was sitting neatly on the countertop (not tilted) and it immediately registered with an orange LED light at the point of entry for the power connection without having to manipulate or tip the laptop, which is what I had to do with the old adapter, ergo I thought AHA! It MUST be the AC Adapter!  2.  Started it up and got three long beeps.  Checked BIOS records for HP Pavilion G7 2017 and learned it could be hardware related.   3.  Replaced the original 4GB RAM with borrowed Geek Squad matching test RAM and tried to power again. 4.  Success!  New RAM and borrowed adapter did the trick, assumed it must be RAM issue.  5.  Bought replacement 4gb RAM stick, installed, rebooted to double check while it was plugged into borrowed AC Adapter -- everything booted fine.   THEN: 6.  Got home and plugged in my old AC adapter but no orange LED to tell me it was registering.   7.  Tipped laptop on its side and voila!  New RAM plus Old AC Adapter still had to be tilted on its side.  8.  Put old RAM back in and tried again; same result -- old AC adapter only registers in the power connection when the laptop is placed on the left side with cord sticking out the 'top' or when lightly pressed on the underside of the center of the laptop, though this latter is incredibly finicky.   The fact that a borrowed adapter worked fine but this old adapter only works when the laptop is tilted is what keeps me thinking it's AC Adapter itself but could still be a connection issue or other hardware issue.  Am I totally off base?  For what it's worth, I've ordered a new AC adapter to try it out again.   Any thoughts out there?   Thanks! Erica
