Specs: Windows 7, amd athlon 64 duel core 5000 2.6g
i am trying to install 2 of these to replace a 1gb ddr-5300. the computer runs fine with them but when i run world of warcraft it has problems accessing random files from the warcraft folder.

Might try setting bios for ram to auto or failsafe or default.

Boot to the windows DVD or boot screen for Memory diagnostics. Let it run a while.

"Might try setting bios for ram to auto or failsafe or default"

Actually you should enter the BIOS & configure the memory settings according to the RAM manufacturer's specs. Pay particular attention to the voltage.

I'd worry if I had to select what should have been set automatically.

To be sure read both the Computer manual and the web site FAQ for your memory.

It's NOT a good idea to randomly buy ram. You must make sure it will work in your system BEFORE you buy it, otherwise the ram may not be 100% compatible with your moard.

Ram that works in another mboard , or any ram you buy or have lying around, may not work properly, or sometimes, not at all - even if it physically fits and is the right overall type (e.g. SDram, DDR, DDR2, etc.; PCxxxx, xxx mhz) for your mboard. In the worst cases of incompatibilty your mboard WILL NOT BOOT all the way with it installed, and the mboard may not even beep - the ram has to be compatible with the mboard's main chipset, or in the case of recent mboards, compatible with the memory controller built into the cpu.

If you still have the ram that was installed when the system worked fine, try installing just that ram.

See response 5 in this for some info about ram compatibilty, and some places where you can find out what will work in your mboard for sure:
Correction to that:

Once you know which module ID strings work in your mboard, you can get them from anywhere you like that has ram with those ID strings.

If you have brand name ram, it is usually easy to look up whether it's ID string is in a list of compatible modules found by using your mboard or brand name system model number.
If the ram is generic, that may be difficult or impossible.

A common thing that can happen with ram, even ram that worked fine previously, is the ram has, or has developed, a poor connection in it's slot(s).
This usually happens a long time after the ram was installed, but it can happen with new ram, or after moving the computer case from one place to another, and I've had even new modules that needed to have their contacts cleaned.

See response 2 in this - try cleaning the contacts on the ram modules, and making sure the modules are properly seated:

Some ram manufacturers do not strictly adhere to the Jedec standards that most mboard bioses use to determine ram settings.
In that case, the ram settings in the bios Setup that the bios has automatically chosen may not be correct.
Check the ram settings in your bios - the ram voltage, and the ram timing numbers - those should be the same as for the specs for modules themselves. Often the ram voltage and timing numbers are printed on the label on the modules.

If the voltage setting or timings settings in the bios are different from the specs for the ram, change them in the bios. The timing numbers must be as close as you can get to the same, or slower timings (higher numbers = slower) - you won't notice the difference the lower settings make.

If you have a mix of different modules
- don't mix ram that specifies different voltages - the bios will force the ram to use the lowest voltage, if "by spd" or similar is used (default settings) - ram that specifies a higher voltage is more likely to not work properly in that situation.
- the bios settings must be those for the slowest timing settings of all the modules, or slower (higher numbers = slower).

If your ram passes a ram test, it's working fine, even if you can't determine whether it's listed for your mboard or system model anywhere.

If you do a ram test, do that AFTER having tried cleaning the contacts and making sure the ram is seated properly - otherwise any errors found may be FALSE.
If the ram is incompatible with the chipset, or on more recent computers, incompatible with the memory controller built into the cpu, it will likely FAIL a ram test - that is NOT a true indication of the ram being faulty - there is probably nothing wrong with it, and it will pass the test if installed in a mboard it is compatible with.

If you want to try a memory diagnostic utility that takes a lot less time to run a full pass than memtest86 does, this one is pretty good - Microsoft's
Windows Memory Diagnostic:
It can be toggled (press T) to do a standard or a more comprehensive set of tests - use the default 6 test one first - if it passes one pass of that, use the latter one. A few of the tests in the latter set are intentionally slower.
If you don't have a floppy drive, see the Quick Start Information at that Microsoft link for how to make a bootable CD of the Windows Memory Diagnostic (you need Windiag.iso - you don't necessarily need to use the program they mention to add it to the CD).

If you have checked out all of the above, your ram tests fine, and you're still having problems with Warcraft...

Check your hard drive with the manufacturer's diagnostics.
See the latter part of response 1 in this:

Hard Drive Diagnostics Tools and Utilities

If you don't have a floppy drive, you can get a CD image diagnostic utility from most hard drive manufacturer's web sites, but obviously you would need to make a burned CD, preferably a CD-R for best compatibilty, on another computer if you need to.

If the hard drive itself tests okay, any data problems found can be fixed, one way or another.

If the hard drive tests okay, it's not unusual to have problems with only a game or games - games are often leading edge software and tend to have more bugs in them than most programs.
Check out Warcraft's web site to see if there are mentions of your problems, and/or updates or patches for your version that you can install.

If that doesn't help, often games DO NOT work properly on all systems that meet at least the game's minimum requirements.

"I'd worry if I had to select what should have been set automatically"

According to the JEDEC standard, all DDR2 RAM is supposed to run at 1.8v. However, a lot of so-called "performance RAM" runs at 2.0v, 2.1v or 2.2v. If this is the type of RAM he has & the BIOS defaults to 1.8v when set to AUTO, it could very well cause a problem. That's why manually configuring the memory settings is recommended.

If you replaced the old ram because it failed, it could be possible that the old ram damaged your data on the hard drive. If that is the case then disregard all the rest. You won't be able to fix data files that have been damaged by faulty ram.

Are we talking about this stuff? GeIL GX21GB6400DC
for the specs. See if it is reporting correctly.

Run memtest. Can't hurt to try reseat.
