I am upgrading my pc's memory to 1G. However, my current motherboard only support DDR266, but I do not want to buy the DDR266 because it is a bit too old. What if I buy two 512MB DDR400 and run them at 266Mhz? Will there be any stability issue due to running DDR400 at DDR266?

why not buy a new mobo, if this is an AMD system you can get great mobo's for cheap now, i.e. the albitron kx18d pro is around $50 (usd) and i hear it oc's great, or you could go with the nf7-s or dfi ultra infinity both around $100. this way you can put that ram to use the way it was meant.
yea my DDR400 is clocked down to 333 and I havent had any issues you all doest run as hot either since its not working at its max power. You should see your ram be EVEN more stable like they said before since its slower then its limit.
definitely get the 400 ram. it's not even the stability as much as the timings. cheap ddr400 runs sloppy timings at 400mhz, but downclocked it'll easily run at cas 2, which is nice. good ram is a bit of a waste, running it super slow like that, but prepares you for future, as i'm sure you'll upgrade eventually.
I change my hardware so often I can hardly keep track anymore...
Currently X2 4800, 1 gig Redline, X850, Dfi Mobo, etc. which may or may not be current at time of posting...
will u should try adjusting that FSB/Ram Ratio in the BIOS, get it to 200 instead of 166, i was actually able to run DDR 333 at 400 speed by adjusting timings first then setting that Ratio to 200, ran the system for bit then put the timings i was using back on.
hi, im way behind on hardware and the tech know-how and i would like to ask about using the ddr pc400 chips on the older asus a7v266-m motherboard... like is that possible to do? what do i have to adjust in my BIOS settings or if i need to do anything there at all? and any other helpful info that you could throw in regarding said motherboard and the switch from pc266 ddr to pc400 ddr
thanks for your time
It's fine to use them, they will just run at 266 rather then 400.
Never be afraid to try something new. Remember, amateurs built the ark. Professionals built the Titanic.

Upgrade your mb for 45-50 bucks and get the faster ram.
I upgraded to, 2 gigs 400 corsair from 1gig 333 and got a 15-25% performance boost. 1k extra on benchmark scores. Think 3dmark 05, I forget.
About my spelling, If you say anything about it im gonna hunt your nerdy english aniel retentive arrrssse down and beat the elcrapo right out of you!!!!

Ryan, no such thing as DDR pc400. DDR400 is known as pc3200--3200 reflects the bandwidth, not the effective clock rate unlike non-DDR such as pc100 and pc133 where the number is the clock.
Go with DDR400 if it is fiscally feasible. DDR266 has risen in price because the quantity available is falling. Replacing the motherboard probably won't gain much if any performance because, chances are, the CPU is running at 266 FSB as well. Now, putting DDR266 in a computer with a motherboard and processor meant to run at DDR333 or DDR400 is a serious mistake.

It depends on what you're using it for. If you're doing something that is time intensive, speed is generally better. If you're have a lot of different programs open at once, more RAM is usually to be favored.
My Laptop has 2GB DDR3 RAM. Whenever I open Task manager, i can see that only 700-900 MB RAM is in use. Usage hardly goes above 1GB even when many programs are running.
The Windows are 64Bit windows 7. Will installation of more RAM will increase speed of laptop? Why or why not?
Also, the laptops and PC use pagefile on harddisk which is used as Virtual RAM. If laptop has 2GB of RAM, will disabling pagefile usage to zero affect the speed of laptop? Speed will increase or decrease? or any other useful/harmful effect?
