Is it overclocking if memory is rated at 400m

Specs: Windows XP, Athlon XP 2100+ Thoroughbred
The motherboard is a Gigabyte GA-7VAXP. It has 1.25 GB of Kingston Value Ram #KVR400X64C3A installed. Kingston advertises that this motherboard uses this RAM. Gigabyte also says this motherboard supports PC3200 400mhz memory with specific types listed on a memory compatibility cart that was made about 6 years ago. I would like to get the maximum performance out of this computer without jeopardizing the system I decide to upgrade the memory and install 3 GB of new memory. The 1 GB module of Kingston is the first step.

I also plan to upgrade the CPU to an Athlon XP 3000+ Barton (333z) in a few days to increase the speed from 1.74 mz to 2.17 mhz. Gigabyte said I should upgrade the BIOS to F!% which I ave already done.

When I installed the 1GB Kingston module it was still automatically detected at 333MHZ. THe BIOS has a smanual aetting to increase the memory speed to 400MHZ which I tried once and the sytem booted with this setting. However Gigabye recommended leaving all settings on auto.

Is it overclocking to manaully set the memory speed to its rating?

Is there any danger of damaging the system if the memory setting is set manaully at 400MZnstead of leaving the setting on auto?

I would appreciate any helpful comments and suggestions.

Thank you.

Your CPU runs at 333MHz so that is the speed your RAM should run at. If you set it to 400MHz, you'll take a performance hit.

In other words ratio 1:1.

It seems that you feel you can make a faster PC, the upgrade cost will far outweigh the value of the PC, it is outdated and pasts its best technolgy.

I recently bought this for £50.00 and was able to unlock the Sempron to a Dual-Core:

Thank you.

You made a nice UK E-Bay purchase.

However, it is not practcical for me to make UK E-Bay purchases. The shipping costs would be far more than the purchase price.

The purchase of a few modules of memory and a used CPU (with minimal shipping costs) is far less expensive than the outlay for a new motherboard, CPU, DVD burner(s), hard drives, video card (if one is not on board the motherboard), etc., and shipping costs.

Running at 2.17 MHZ with the ability to have up to eight ide devices, and five card expension slots are advantages to this motherboard over some of the newer ones with only a few expansion slots. There is no question that newer technology and SATA drives are faster than IDE drives but this motherboard still has some life in it.

And, some of us still like to tinker with older mother boards and learn frrom our experiences.

However,, thank you very much for your thoughtful suggestion.

Sorry if I double posted. I am new on this board and just learning how to use it. Thank you.

If you want to invest money in an outdated system, that's your business. If you want it to run at it's best, both the CPU & RAM should run at the same bus speed. As kuwese pointed out, 1:1 ratio. Anything other than 1:1 is less than optimal & you're taking a performance hit. You're not doing your system any favors by running the CPU at 333MHz & the RAM at 400MHz.

Then I am wondering why Gigabyte would tell me that this motherboard supports PC3200 400mhz memory and that if the auto select does not detect 400mhz memory then there are compatibility issues with the memory and the memory board. I really don't want to invest in a new system when all I was trying to do was move from 2 GB of memory to 3 GB of memory and I already have another CPU to install on this motherboard. I really don't think these sites should be for sarcasm either.

I have reviewed the comments on this board and will consider them. Thank you.

Then should I underclock the memory to 266 instead of having the motherboard BIOS set to auto for RAM speed since the current CPU that is installed is running at 266mhz even though the auto setting recognizes the memory at 333mhz. Then it would be 1:1.

(The CPU that I plan to install will run at 333mhz).

Please excuse my seemingly ignorant questions as I am a neophyte.

There is no reason to get upset, everyone is trying to help you. They are pointing out that increasing the memory speed, while it is not a problem (as long as you are not mixing together slower memory with the newer memory) increasing the memory speed to it's maximum or rated speed, it will actually cause the system to have to pause to wait for the CPU and memory to get back into sync and actually cause your system to run at LESS than it's optimal speed UNLESS you overclock your CPU to run at a bus speed of 400 also (if your board supports 1600FSB). That is not sarcasm, it is a fact that many a serious overclocker will underclock their RAM to get it into sync with their CPU speed for better overall performance. They also are trying to advise you that at some point putting add more money to an already outdated system gets you much less return on investment and often is not worth what you are adding to it. I went down that road for a while, thinking I could avoid a big expense it I could just get the old one just a little bit faster, I would be happy. I found the fastest CPU the board could take, maxed out the RAM, overclocked it as far as I dared (orig. 1.6GHz to e-bay find 2.6GHz OC'd to 3.2GHz), upgraded the graphics card as far as practical with the AGP2x interface....I was 'satisfied' for about 5 or 6 months. After considering a few more schemes for more speed, I tore up all of my notes and started from scratch. Been much happier ever since.

You have to be a little bit crazy to keep you from going insane.
