I think we have some confusion here, on my part. 🙂 I thought (having
second thoughts now) the person that asked how fast the ram was on his
vid card was asking the speed rating of his ram. As you know various
manufacturer's use various brands and speed of ram on their cards.
Mine is built by ATI 9800pro and it has Samsung 1.8ns ram, a lesser
brand may use 2.0ns ram. This is what I thought he was asking about
and not the mhz the ram is actually running at. But it is very
possible I am wrong and he wanted to know how to find out the mhz
speed his ram is running at.. Sorry for the confusion.

yep, and the FX5900 I just gave my son (I kept the new Radeon 9800 Pro!)
for his birthday has a core clocked at 400 mHz and memory is clocked at
425 mHz (850 DDR)...and it performs slower than the 9800 Pro with the
default clocks :)

Is so! 😱p

That reading is from PC Wizard 2004 and is made by the same people who make
CPUID . I would trust the reading this program gave the original poster, not
just assumptions.

I think i got my wires crossed too!!!

Neo, what are you doing on that side of the screen again! You soddy lad, get
out of that damn matrix and give me a hug!

Ah, my new Built By ATi Radeon 9800 Pro-128 is a Revision 'F' board and
the ram chips nomenclature starts with an HY-???? I believe this is
Hyuandai? (sp?). To my experience, both Samsung and Hyuandai produce
reliable parts generally. I have a readable photo clip of one of the
ram chips. There are 4 lines, they are :

HY50U283222
AF-28 318A
S
KOR 7L40389T

So, where/what says the speed of the chip?

Understand that the nanosecond rating of the RAM, 1.8ns, 2.0ns etc... is not
the inherent speed of the RAM, meaning... the RAM is not then hard-coded to
run at 1.8ns or 2.0ns respectively. Instead, the nanosecond rating is a
measurement of the maximum reliable tested threshold of the RAM. There will
be variations between the maximum attainable speeds of identical RAM chips
out of a batch of 1000, just as CPU's will vary from one to another out of a
batch of 1000. The fabrication process for RAM and CPU's is designed to
maximize the yield of good parts, and afterwards measure each individual
part for tolerances. When chip A does 1.8ns it gets a gold star. When chip B
does 2.0ns it gets a silver star... so to speak, and they all get sorted and
shipped out.

So then what DOES determine the speed of the RAM? The speed of the RAM is a
combination of its clock rate (i.e. mhz) and core latencies. One could argue
whether or not RAM's SDR or DDR nature should be included in this category.
I really don't know. Does bandwidth equate to speed? Not always. I guess
it's a matter of semantics.
