Just bought a 8800 GTS, http://www.newegg.com/Product/Prod [...] 6814130325 to be exact.
 
Specs say its Memory clock is 1940MHz.
 
Plugged into my system the memory clock is 972MHz.
 
I'm on a older mobo that doesn't have PCI-E 2.0. (Just PCI-E standard). Could this be why?
 
Any info on this?

There is a simple answer to this question. When you calculate the Memory speed of a video card, you multiply it by 2 to get the 'effective' memory speed. Therefore 972 X 2 = 1940 Mhz. That is where those numbers are coming from. Also, keep in mind when you see somebody say that they increased their memory from 2000Mhz to 2200Mhz etc... The amount that they overclocked would have only been 100Mhz.

spec's I'm looking at say 1.0Ghz Clock

I hope that helps, also, I may be wrong on some specifics in my answer, but that is the general idea. I am not a computer genius by any means.

^You're right. ATITool will give you the effective speed. It should work for your card, it works for a lot on Nvidia cards. If not it won't hurt anything, just uninstall it.

 
THOSE LYING NEWBS!!!
HOW COULD THEY DO THAT??????
 
IMMEDIATELY DEMAND A REFUND!!!!
 
judging by what you said, Id blame the MOBO/GFX card/w.e program you used to check the speed.

 
 
 
Well, it depends on what speed type you are looking at. If you see 1000Mhz when you 'should' be seeing 2000Mhz then it is really a user error for not realizing to double the memory speed to get the effective speeds of the card. With that being said, they really need to do away with these kinds of things...and CPU multipliers and all that garbage, let's all leave the math parts out of computer issues.  

Wrong card.

Uh, he was joking. The part in caps that is.

Yea, I know, I was commenting on his final thoughts.

Sum1 kill me please.
 
Dude, just do a search ffs pls now thx k bai!

 
 
What is this, Myspace ???  

lol, thnx guys, I know it was a noob question, and doubling the number GPU-Z was showing did cross my mind..
 
It's also cut in half on Rivatuner as well.
 
Just thought i'd double check how it works.

If you go into the Graphics "Subsystem Diagnostics Report" in Riva you will find that it does tell you both. Here is a cut and paste from mine.
 
Memory clock              : 688.500MHz (1377.000MHz effective)

you can zorg me anytime you 1377Mhz effective graphics card DDR memory stud .

^Are you giving me S you P? Because if you are, understand this phrase... Above Me.. Beside Me... Balow me.
 
I don't answer to you, I answer to myself.

I just checked "your" website and it took 5-10 sec to load... too long.

Leave Rachael Ray alone. More ridicules, I clicked on the link to see what you were whining about and came back to your main page. Painfully amusing.

Grow up before you start pissing.

In your defense it did load faster on more tries. but you are still a ..........

Out of curiosity, what made you bust my balls?

How was I busting your balls, champ?
You just made this topic cry with your posts
GOOD DAY!

Easy answer:  DDR2 (memory clock times 2)
 
I believe the difference on the PCIe is the amount of data transfered to the mobo so PCIe 2.0 would be twice the speed of data to mobo and back to GFX.

Ok, you weren't busting my balls, you were pissing on me stud.

your welcome!
