    I am searching fo a new videocard and im looking at many spects, i want to know if 4ns memory chips are fast or slow?

    I am looking at the EVGA fx5600 with 256 meg, real cheap for what i can see, will it be slower than an MSI of asus??

    Old standard ram was 7-8ns.
    So 4ns is good.

    As far as I know Evga is a good name brand from what I have read here. I have never owned one so I don't know. I think they are a relatively new company though too. Don't quote me on that though. Its just something I remember I recall from my readings.

    It should be a good car.

    some radeon 9500's are like 3.3ns. the smaller the number, the faster and more stable. 4 should be alright i think. i have an fx 5600 and i dont really like it. i personally would go for a 9600 pro. you can get them in 128 or 256 but i dont think you need the 256 unless you want bragging rights. we dont even fully use the 128megs of memory, much less 256. we wont need the 256 until doom 3 comes out at least.

    dont get the 5600! I have one and its slow compared to my ti 4200. you sould go with a ati 9500 or ti4600 for a low price card, or just save for the ati 9800.

    4ns isn't all that impressive imho. It seemes that on the cheaper 3D cards with 256MB they cut costs by using lower specced memory. Good = 2.8ns or better, average = 3.3ns, poor = 4 - 5ns. This greatly affects the memorys ability to overclock. On a 9500 card with 3.3ns ram I found very little room for overclocking. The ability to overclock is also dependent on the manufacturer of the mem chips. (Samsung, Infineon, etc).

    You can figure out the rated speed of the chips by the 1000/n method, where n is the nanosecond rating. In your case:

    1000/4 = 250

    250mhz, or 500mhz ddr would be the max physical speed of those ram chips. Not very impressive at all.

    My 9700np came with 2.8ns samsung chips, which comes out to about 357mhz. They top out around 325 though as you can never expect to get the absolute max speed out of every chip on the card.

    Wow thanks for the reply!!
    I will use your method Sovereignty 1000/n=bus speed
    Can i use this formula with the speed to get the speed (ns) of memory chips??

    Ant the faster ive seen is 3.3 on a Asus ti-4800se.

    Thanks for your advice, ill look for a TI or a 9600 pro, cost more tho. Just checked, the 9600 pro is 3.3ns and the non-pro is 5!!!
    AAAA now i see why people say to stay away from non pro!

    Thanks for all guys!

    There is a 5600 Ultra with the good memory chips clocked at 400/800 and is capable of Ti speeds and more. The memory clocks up to around 900.

    Yes a Ultra is good but not in my price range, that is why i am considering a ti-4200 or at the limit a 9600 pro...im on a tight budjet!!

    Ti4200s can be had for around $100 and 9600 Pros are around $150. Both are great overclockers and are about the same speed. The 9600 Pro supports DX9 though.
