Are there any taxes charged on importation of memory into other countries? If there is, can you send it marked as a gift?

Fri, 11 Jul 2008 23:15:43 GMT

We have no control over customs fees into countries and so it really varies from country to country on how much is charged, if anything. (Some people suggest we add the Import taxes/fees into our prices so you just pay everything at once, but it's really up to their country's customs. We have no say in the matter and do not see a cent of what is charged.)

Customs also levy heavy fines against us if we did such a thing (marking it as a gift when it's truly not), so we cannot do that on your behalf.

Do you sell to the general public or just business to business?

Wed, 09 Jul 2008 21:33:21 GMT

We sell to everyone! We welcome orders online via phone or e-mail, and schools and government institutions can read the details on being setup for terms so that we can accept Purchase Orders. We also work with resellers around the globe.

Can I mix different memory speeds?

Fri, 11 Jul 2008 23:39:11 GMT

You can use modules of different speeds as long as they are faster than what you already have. It is recommended to use the same speed as what is already in your system to ensure stability. If you do mix speeds, the modules will all run at the speed of your slowest modules.

Can I leave in the 128MB ram that is already in my computer, or should I take it out when I install my new 512MB?

Fri, 11 Jul 2008 23:36:49 GMT

You can leave it in and it should work just fine together. Memory doesn't always have to be the same size for each slot. As long as the type matches up, they should be able to work and sync-up the speed (e.g. a PC133 module and a PC100 module in the same machine would make them both run at PC100 since it's slower for one of them, but makes them all run on the same level and be more compatible.)

Windows and the 4GB Limit

Wed, 09 Jul 2008 18:23:56 GMT

My system says the maximum is 4GB, so I've installed it BUT not all 4GB are showing up in Windows. Is there something wrong with the memory or my machine?

There is nothing wrong with the memory or the machine itself - 32-bit operating systems have a limit of 4GB, but that also includes where attached devices (e.g. sound card, video card, Ethernet, modem, etc.) are stored within Windows. In other words, the better the system you have, such as a higher end video card with a large amount of memory on-board, the less memory you'll have access to from the 4GB.

There's a Microsoft support article talking about this in regards to Windows Vista.

There's also a good semi-technical article summing up the basics of what's going on behind the scenes, which should help give you a clear idea of the situation.

Buyer's Checklist - Make sure all your bases are covered.

Fri, 11 Jul 2008 23:32:36 GMT

Get the Right Type
Does your motherboard accept SIMMs or DIMMs?

Get the Specifics
Once you find out what type of module, make sure you're getting the right:
Type (regular vs. EDO vs. SDRAM)
Speed (measured in nanoseconds)
Parity or nonparity

Play the Math Game
Are you making the most out of your open slots and existing memory? Make sure to get the ideal amount for your empty slots, so that you never have to throw away any old modules to make room for new ones.

Can I pick up my order?

Wed, 09 Jul 2008 20:06:57 GMT

Yes select will call as the shipping option

I just want to know howcome my tracking number is not working? Priority International mail is the shipping method.

Fri, 11 Jul 2008 23:10:47 GMT

You cannot track Priority International mail packages online with the USPS. They may update that information when delivered.

Can I install an ECC DIMM on a Non-ECC motherboard?

Fri, 11 Jul 2008 23:36:06 GMT

Most motherboards that do not have an ECC function within the BIOS are still able to use a module with ECC, but the module will run in non-ECC mode.

Keep in mind, there are some cases where the motherboard will not accept an ECC module, depending on the BIOS programming. The only sure-fire way to test this is to place the module in the motherboard and see if the BIOS will recognize the memory addition.

Can I use DDR PC2700 memory in my machine if it shipped with DDR2 PC2-4200?

Fri, 11 Jul 2008 23:44:40 GMT

No, actually. DDR (aka DDR1) is incompatible with DDR2 memory. DDR1's speed range from PC1600 to PC3700 while DDR2 ranges from PC2-3200 to (as of right now) PC2-6400.

DDR1 memory for a desktop has 184 pins while the DDR2 equivalent has 240 pins. Both DDR1 and DDR2 for a laptop has 200 pins, but the design is different to keep you from installing one type of memory in the other's slot (and possibly damaging the machine).

My order was voided, why was I still was charged?

Fri, 11 Jul 2008 23:13:31 GMT

The charge you see is simply a pre-authorization and will disappear after a few days, orders are not charged until after they ship.

Can I mix ECC and Non-ECC DIMM Module ?

Fri, 11 Jul 2008 23:40:21 GMT

No. When adding new memory, you need to match what is already in your system. ECC (error checking and correcting) modules have an extra chip that detects if the data was correctly read or written by the memory module. If the data wasn't properly written, the extra chip will correct it in many cases (depending on the type of error). Non-ECC (also called non-parity) modules do not have this error-detecting feature.

You can determine if your system has ECC by simply counting the number of black memory chips on each module. ECC (and parity) memory modules have a chip count divisible by 3. Any chip count not divisible by 3 indicates a non-parity memory module.

Can I ship to PO Box?

Wed, 09 Jul 2008 20:05:26 GMT

Yes but you must select a USPS shipping option.

Are PC133 speed-tested SDRAMs backward compatible with PC100?

Fri, 11 Jul 2008 23:28:44 GMT

Yes. The AC timing specifications on a PC133 device are tested to allow a system bus to run at 133 MHz.

The PC100 and PC66 timing specifications are more relaxed on these timings.

Majority of PC133 chips should work at PC100 and PC66. In fact, a -75 device is specified for PC100 timings using CAS latency = 2.

Please refer manufacturer data sheet for AC timing table in the appropriate data sheet tCK at CL = 2.

Can I use PC133 or PC100 SDRAM in my PC that has a 66MHz front side bus?

Fri, 11 Jul 2008 23:45:09 GMT

All SDRAM is backward compatible and can run at any bus speed slower than it is rated to run.

For example, a PC133 SDRAM DIMM is capable of running at 133MHz, 100MHz, and 66MHz. There are a few older motherboards that require 66MHz SDRAM and that will not accept PC100 or PC133 SDRAM, but they are the exceptions to the rule.

Keep in mind that your memory run will only run as fast as the slowest component installed. If you install PC100 memory on a system with a 66MHz front side bus, the memory will only run at 66MHz.

512MB PC3200 184 pin DIMM ECC Reg Question - What does the Reg after the ECC mean ?

Fri, 11 Jul 2008 23:27:35 GMT

DDR and SDRAM can be unbuffered or registered. EDO and FPM can be buffered or unbuffered. Buffered modules contain a buffer to help the chipset cope with the large electrical load required when the system has a lot of memory. Registered modules do not have a buffer but do contain a register that delays all information transferred to the module by one clock cycle. Buffered and registered modules are typically used only in servers and other mission-critical systems where it is extremely important that the data is properly handled.
