I am sorry, but i can't find anywhere memory speed of GeForce 6 Series. I want to buy one. Maybe 6600, but i don't know it's memory speed(nanoseconds).
Maybe somebody knows?

The 6800Ultra has 1.6ns or 1.8 GDDR3
The 6800GT has 2.0ns GDDR3
The regular 6800 has slow @ss regular DDR. ;)

I am sorry, but can you tell me what is memory speed of ordinary GeForce 6600?

OMG my GT memory speeds is 0.4 billionths of a second slower than an Ultra! :rolleyes:

Wich equals several hundred mhz!
:rolleyes:
Edit: Oh a GT. :) Then it's not too much difference. :D

6600 GT comes with 2.0ns DDR3 (128-bit). As for the other cards:

6800U 1.6ns DDR3
6800GT 2.0ns DDR3
6800NU 2.8ns DDR (a few with 2.5ns and one or two with 2.2ns).

Keep in mind that the 2.0ns in 6800GT may in fact be 1.6ns (wrongly badged by Samsung), else how would you explain there are several GT's that run high on mem (mine does 1200).

1.6ns memory is meant to do 1200MHz stock, so just because you reach 1200MHz doesn't mean you have 1.6ns memory. Seeing 1.6ns is meant to run stock at 1200MHz (nVidia underclock it obviously), I would think that if you can't go any higher than 1200MHz that you must have 2.0ns memory.

So far my Gainward Ultra/2400 6800GT has made it up to 1220MHz stable and 425MHz on the core. Today is my first day overclocking so i'll see where I can get from here with more testing... I doubt i'll get higher without a voltage mod though.

I didn't say I can't go higher, but I don't want to risk it anyway. 2.0ns is made to run 1000MHz, if I run 1200MHz with no problems, then surely it must be 1.6ns, or at least that's my opinion. It's really true that Samsung mislabeled them as 2.0ns when they're really 1.6ns, I read about it somewhere.

Yes I know of the situation. I guess since you can go higher like me that you may be right. Still, most people with GT's are getting around the 1100-1200 mark, so either it's just luck of the draw (and some have 1.6ns) or just some 2.0ns overclocks very well.

Either way, we're both lucky and I'm glad I switched to Gainward while I had the chance.

It might just be that 2.0ns overclocks really well. Either way, we're both damn lucky. :nana:

BTW, Gainward is coming out with a 6600 GT "Golden Sample" kind of model with 1.6ns DDR3 (128-bit). That one should overclock pretty well for those who want a 6600 GT. :ORDER:

But what about memory speed of GeForce 6600 with DDR1 (Not GT)?

Hmm...whenever I do "test optimal settings" for OCing, I always get 1.11GHz for the RAM...I wonder what I have. Maybe 1.8? I run it at 1.1GHz without any problems, but I don't want to go any higher.

From what I gathered from Samsung's website, 3.6ns RAM would be 275MHz, or 550MHz DDR. So there you have it Myp3ik, 3.6ns.

1.8ns = 1100MHz
3.6ns= 550Mhz

Some of the 6600's are only clocked at 500MHz, which would of course be 4.0ns.

To determine speed,


Divide 1000/ns rating.


1000/2ns = 500 (1000)

1000/2.2 = 455 (910)

1000/1.6 = 625 (1250)

Actually the Samsung 1.6ns chips are somethign like 1.625 and rated for 600 (1200) not 625 (1250).

That still doesnt change the formula, If samsung mislabels their products.

Obviouisly, But he did imply that Samsungs 1.6ns Memory is not the correct speed, I'm not quite sure why he chose to quote me, in such a regard, as almost a correction.

You guys touchy.
I didn't intend to criticize any formula. I just corrected something that was wrong.
Samsung 1.6ns chips are meant to run at 600mhz and not more. That's all i wanted to say and i think it's all i said as well.


Edit: Do not circumvent swear filter please.

I agree with Mustrum: Don't be so touchy!

All he was doing was providing additional (useful) information. I am a neutral onlooker here and it didn't read as being confrontational or anything.

You should try usenet if you want to see some real abuse!

Now lets lighten up, shall we guys?
