How to Upgrade Memory Speed



There are few ways to increase the speed of your computer's memory. Firstly, the speed increase the memory by the BIOS (Basic Input / Output System). This is the basic software that allows devices to your computer to communicate with the operating system. Second, it is sufficient to upgrade the memory modules your system. This requires a bit of light hiding in your computer. In both cases, it is important to perform each task safely and correctly.

Instructions

Increasing the memory speed in BIOS

1. Turn on your computer. Follow the instructions on the startup screen to enter the BIOS menu. The splash screen tells you to hold down a key or key combination to enter the BIOS.

2. Use the arrow keys to navigate the setup menu Clock RAM in the BIOS setup window. The RAM clock settings menu allows you to raise and / or RAM clock speeds down.

3. Use the arrows left or right to increase the memory clock speed to desired speed.

4. Restart your computer, and test your RAM speed has increased on a memory-intensive program. This typically includes a game or a program of multimedia design, as appropriate.


Upgrading Laptop Memory

1. Turn off your laptop via the Start menu of the operating system. Unplug all cables and external devices from the laptop. Close the display panel, and put the laptop down with the front of the laptop in front of you.

2. Remove the battery from its compartment on the bottom side of the laptop. The battery is held in place by one or two release buttons. Then remove the lid of memory and screws Phillips head of the center of the laptop.

3. Separate clips at each end of the memory module within the memory compartment. Tilt the module upwards at an angle. Then, pull the memory module from the memory slot. Repeat for each module, you remove the laptop.

4. Place the new memory module into the empty memory slot at an angle upward. Make sure the notches on the small module align with the notches in the memory slot. Press the module until the retaining clips of the slot to break the module into place. Repeat for each module you install.

5. Replace the battery compartment and memory retention screws. Replace the battery. Reconnect all cables and devices to the laptop.


Upgrade computer memory

1. Turn off the computer. Disconnect the main power cable on the rear panel of the computer. Disconnect and remove all devices from your computer. Touch an unpainted metal surface to ground yourself before opening the box office.

2. Position the computer so that the back panel is facing you. Place foot on his left side. Remove the screws or release the latches securing the access panel right side up. Remove the side panel to reveal the computer inside the computer.

3. Locate the memory modules near the center of the motherboard. Spread the retaining clips at each end of the memory module that you want to delete. Remove the module from its compartment. Repeat for each module, you withdraw.

4. Align the notches on the new memory module with the slots inside the compartment empty memory. Place the module into the compartment, then press the top edge of the module until it snaps. Repeat for each module you install.

5. Replace the side access panel and reconnect all cables and peripherals to the computer.

Silicon Power SDHC Class 10 32GB Memory Card

Author: Chris Ramseyer


Introduction
We all have products that use the Secure Digital Cards. SD has been adapted by nearly all consumer product makers in one form or another. Which form is another story entirely, as there are so many and within each category there are speed ratings. Some devices need to be able to operate above a certain speed to be able to handle the tasks given. This is where the class structure comes in.

Most storage products are rated at a maximum speed, the highest peak performance possible under ideal conditions. This works out well when everything you are doing is well within specifications, but there can be times when a minimum speed is required. SD products are rated at a minimum speed, the Speed Card Rating. A Class 2 SD card can write at least 2MB/s, a Class 4 SD card can write at least 4MB/s and so on. Devices like HD video recorders require a minimum sustained write throughput. If your device needs to be able to write at 6MB/s but can only write at 4MB/s, then your video will suffer from dropped frames, lost audio or be completely corrupted. Currently Class 10 is the fastest available on the market and it has a minimum speed of 10MB/s.

Today we are looking at the Silicon Power SDHC Class 10 with 32GB of capacity. This capacity size makes it perfect for photographers or those looking to record high definition video. Let’s take a look at the specs first up.

I have to admit I really like the new class standard that measures the minimum performance and glad they got off of the ‘x’ standard. Silicon Power has released their new Class 10 SDHC cards in four capacities; 4, 8, 16 and 32GB. To go larger in this format you have to look towards SDXC (eXtended Capacity) standard.
Silicon Power isn’t in the US market as heavily as it once was. We were only able to find one US seller of the Silicon Power SDHC Class 10 32GB and it was a specialty shop catering to professional users. All Pro Sound lists the 32GB model like we are reviewing today for 134.99 USD. They also list the rest of the Class 10 SDHC cards; 4GB (17.49), 8GB (32.34) and 16GB (58.06).

I really wish Silicon Power would import more of their products to the US since they are well made and it would bring the costs down. In relation, we went shopping at Newegg and found other 32GB SCHD Class 10 cards for as low as 59.99.

It should also be noted that Silicon Power offers a lifetime warranty with their SDHC products.

SD card upgrades brick Windows Phone 7 handsets

By Stewart Mitchell

Posted on 15 Nov 2010 at 11:20



Microsoft Phone 7 users have been warned not to upgrade handset memory or use the phone’s SD card in other devices, after it emerged that the handsets alter the memory card’s format.

According to Microsoft, removing the original SD cards can cause data loss and stop the handset from working properly, limiting upgrade options that might have been a key purchasing motivation for media hoarders.

“You should not remove the SD card in your phone or add a new one because your Windows Phone 7 device might not work properly,” Microsoft said on its support site.

“Existing data on the phone will be lost, and the SD card in your phone can't be used in other Windows Phones, PCs, or other devices.”

The company said that when an SD card is integrated with the operating system, Windows Phone 7 reformats the memory card, and creates a single file system that spans the internal storage and the card, locking it to the phone with an automatically generated key.

Because of this, handset memory was never intended to be end-user expandable in Windows Phone 7, stating that the SD card slot was intended for use only by manufacturers and mobile operators.

To reinforce this position, Microsoft said it would disable handsets when consumers removed pre-installed SD cards.

“If you remove an SD card that has already been integrated with the phone, the phone displays an error message that tells you to reinsert the SD card,” the company said.

“All phone functionality is disabled except for the ability to make emergency calls. The phone will function normally again only if you reinsert the original SD card and then start the phone.”

Users can, according to Microsoft, only insert a new SD card before the handset is first turned on or by restoring the handset to factory settings, which would cause data loss.

Microsoft warned that even if a phone appeared to be working properly after the upgrade, problems could arise once the internal memory had filled up.

“In some cases, these performance issues might only be evident after using the phone for some time,” Micorosft support said.

“For example, if your phone has 8GB of internal memory and you integrate a non-compliant SD card with the phone, you might notice the performance issues only after the 8GB of internal memory is filled with applications and media.”

Low Voltage DDR3 Final Thoughts

To summarize, increasing RAM speed will have more of an effect than tightening your timings but the two are very close. When overclocked in line with your CPU then you will get even better results. If you are solely playing games on your PC you will be just as well with a 1333MHz kit as you would with a 2000MHz kit as your GPU is your best tool here. The whole point of high speed memory kits is to allow you to increase your CPU speed higher without having to worry about RAM instability. My max stable overclock had a negative effect due to keeping the CPU as close to stock speed as possible during testing meant it was running slower in this configuration than all other configurations. At 1333MHz the CPU was 133x21 (2.79GHz), at 1600MHz the CPU was 160x18 (2.88GHz), at 2000MHz the CPU was 200x14 (2.80GHz) and finally at 2090MHz the cpu was 209x13 (2.71GHz).

The OCZ Blade ST 2000MHz 4GB kit would possibly be best suited to an i7 series 1156 CPU or one of the 'K' series unlocked 1156 CPU's in my opinion, this is because they have the option of a 2:12 RAM multiplier with their IMC which gives more flexibility and tweaking potential when overclocking either the CPU or the RAM. The i3/i5 CPU's can easily run 2000MHz with a 2:10 multi but there isn't much room left to overclock.

The OCZ Blade ST 2000MHz 4GB kit wasn't the easiest RAM kit to work with, firstly the SPD table looked as if it was designed for Intel Core 2 CPU's instead of the specified Intel 1156 Core i3/i5/i7 CPU's that OCZ advertise on their website, and second there were no CL9 timings or 1.65v voltage settings to select which made setting up this RAM all that more difficult. Most people that buy RAM expect it to run at its rated speed or at least have a profile to select from, those people would more likely return this kit as faulty and cause unnecessary RMA's.
OCZ Blade ST Memory Conclusion

In this section I am going to write a brief five point summary on the following categories; Performance, Appearance, Construction, Functionality and Value. These views are my own and help me to give the OCZ Blade ST 2000MHz Low Voltage 4GB Kit a rating out of 10. A high or low score does not necessarily mean that it is better or worse than a similar RAM kit which has been reviewed by another writer here at Benchmark Reviews, which may have got a higher or lower score. It is however a good indicator of whether the RAM kit is good or not. I would strongly urge you to read the entire review, if you have not already, so that you can make an educated decision for yourself.

The OCZ Blade ST 2000MHz 4GB kit performed very well at lower speeds of 1333MHz and 1600MHz where we were able to lower the voltage to 1.50v and tighten the timings to CL6 and CL7 respectively. Overclocking was hindered somewhat by the IMC on my Core i5 760 CPU as it has a max 2:10 multiplier; this meant that the overclock was dependant on the BCLK. There were no memory errors at 212 BCLK but the CPU was not stable enough to bench with. My max stable overclock of 2090MHz had a negative effect as the CPU was running a little slower than it was at all other configurations tested.

Appearance is subjective and is different to all individuals, due to the graphical nature of our reviews you can easily make up your own mind on what you think. I really like the look, the design is different than other tall heatspreaders. The brushed aluminum is a very nice look indeed and the render and color scheme on the sticker makes this kit stand out. I'm not overly keen on the green PCB but most of it is hidden out of sight by the DIMM slot and catches anyway. The only real blemish on these modules is where the sticker covers the screws and you get little bubbles, but that's just me being picky.

Construction is second to none, period. The heatspreaders are very well attached and are made of some heavyweight aluminum, they feel double the weight of my previous G.Skill RipJaws kit which gives me the sense of strength and build quality that I expect from a premium product.

Functionality is where this kit lets us down, Firstly the SPD table doesn't relate to the product and secondly there are no CL9 timings or settings with 1.65v to choose from which makes things in the BIOS more tricky than they need to be. Honestly OCZ need to take a look at the JEDEC's in the SPD table before they get too many returns due to users not being able to run this kit at its rated speed, sort this little problem out and you will have a winner. If you can and don't mind tweaking you will find this RAM kit will be quite rewarding.

The OCZ Blade ST Low Voltage 4GB kit (P/N OCZ3BST2000LV4GK) has an MSRP of $106.99 at the time of writing this article, this is good value for money and outweighs many issues that may have been raised in the previous sections of this conclusion. For this price you won't get much better I don't think, if you have the know-how and you don't mind spending some time tweaking then I would definitely recommend this kit to you. If you are just a beginner in the overclocking scene you should look past this kit and go for something simpler, unless you fancy a challenge.

Pros: bmr_approved.png

+ Very nice looks
+ Build quality is excellent
+ Very flexible at lower speeds
+ 1T Command Rate at all speeds
+ Limited lifetime warranty and free technical support
+ Great value for money
+ Opens up more CPU overclocking potential
Cons:

- SPD table lacks any worthwhile settings
- No settings for rated speed (CL or voltage)
- Very tall, could possibly interfere with bigger CPU coolers
- No good for beginners
Ratings:

    * Performance: 9.00
    * Appearance: 9.00
    * Construction: 9.50
    * Functionality: 6.00
    * Value: 9.50

Final Score: 8.60 out of 10.

Upgrading and Installing Memory in Computer

Upgrading your computer memory (RAM) is one of the easiest ways to improve speed and performance. Although computer RAM is less a problem today than it was in the past, you might be surprised to discover your computer is running only a fraction of the memory capacity, it can. With RAM being so cheap, maxing out your computer's memory may be the most affordable way of improving performance.

How to buy and install memory

Probably the fastest way to buy RAM is to visit a top online retailer like Crucial or Kingston. They have tools on their site to help you find the type of memory your system requires. In some cases, they will be able to scan your computer and identify the amount of RAM you currently have and give you a list of options on what to buy. The most of your system, you may find that you have to throw the existing modules. For example, if you have two 512 MB modules take two spaces, you want to take those and buy two 1 GB modules

Once you have the RAM, you'll need to open the case and find the memory slots on the motherboard. You will normally see between two and four slots. Sometimes these sites will be numbered and color coded. For example, you could see the numbered boxes on the motherboard as 1-3-2-4, with one and two slots are color and slots three and four being another. This indicates that the RAM should be installed in pairs. So if you have two sticks of 1GB, you want to install them in the 1st and 2rd slots to match them.

You can install one stick of RAM DDR Installed in pairs may improve performance. But always check with the requirements of the motherboard in the selection of memory. Crucial.com has a lot of information on your computer or motherboard and give you an idea of whether your submission should be two or may be installed by themselves.


For technical Installing RAM

Want to put the computer on a solid flat surface such as a table or floor. Open the case. Touch bare metal inside the computer chassis to ground yourself and protecting against electrostatic discharge (ESD). Locate the memory module closest to your CPU. You should find this to be a memory bank. If you install a second stick, to locate two memory banks. Next, open the clips of the current memory. Grab the corners of memory and lift straight up to remove an existing key.

If you install memory in an open slot, release the clips on each side of the bank and match the notches on memory with the keys on the memory slot.


 The memory can be installed only in one direction, so make sure you have these properly aligned to reduce the risk of damaging the motherboard or a RAM module. Press the card firmly down until you hear the clips snap closure.





Do not force the memory if it is wrong. If you experience problems, remove the memory and take a closer look at what you do. The memory should be pressed firmly, but we must go with little resistance.
