SZXX 128MB or 256MB dedicated memory??

Alright, so which is which:

which models of the SZ have NVIDIA GeForce Go 7400 with 128MB Dedicated Memory and which models of the SZ have NVIDIA GeForce Go 7400 with 256MB Dedicated Memory? I'm really confused because sonystyle.com is inconsistant. Also, is there a way you can find out on your own SZ if there's 128MB or 256MB of dedicated memory? Thanks!

 

throguh my knowledge, the SZ does not have dedicated memory nor does the FE. Its runnign Turbo Cache which should be a shared memory technology.
My SZ max is 128 shared

 

All SZ models have 128 dedicated to the 7400 chipset. Where you get the extra 128, for a total of 256, is dependant on the amount of system RAM you have installed. IIRC, the break point is 1GB ram for the resulting 256MB video RAM.

 

Thanks! I'll have the extra RAM in no time (hopefully.)

 

What are you talking about man....It is 128mb dedicated and 128mb shared depending on the amount of RAM you have.

 

lol ive never heard of a dedicated video card with no dedicated memory

 

hrmmm interesting!
I gotta look things up again then.
Cuz I remember one of my computer store friend told me taht turbo cache is a shared memory technology.
My pamphlets only tell me i got 128mb video memory

 

Turbocache is indeed Shared Memory. But the SZ has 128MB dedicated memory and 128MB shared memory if you have enough RAM.

 

See thats where you messed up at. Because computer salesman are always unknowlegable when it comes to current tech.

 

I'll put in my vot for:

The SZ series all use the same video setup. 128M dedicated on the 7400, w/up to an extra 128M available by using turbo-cache to suck a little system memory and bandwidth.Then there is the Intel integrated graphics that uses up to, I think 128M.

 

I have a SZ160, with Windows, the 7400 appears as having 128MB memory.

However, with the Linux driver, it shows as 64MB dedicated and 64MB with turbocache: 128MB total.

I have 1GB of RAM on my vaio, I've never seen it reporting 256MB of video RAM, unlike what Sony's brochures claim

 

Well I have 2gigs in my Unit. And this is what System Information gives me under displays (I still say that its not the available ram you have that gives you 256MB of video ram, I think there are two cards that Sony offers.

My Apeture or however you spell it, size was 256. I did get 189 Ram from 3DMark.

 

Kyoshiro- Where did you read your RAM? Which unit do you have? I have the sz120

 

I read it from running 3dMark06, i have the SZ18GP/C which should be SZ160 Premium i think

 

See- SOny does have a 256mb card.
Btw, whats your score in 3dmark06?

Heres what mine says in 3dmark 06:
NVIDIA GeForce Go 7400 Driver 8.3.0.2

Description NVIDIA GeForce Go 7400
Manufacturer NVIDIA
Total Local Video Memory 128 MB
Total Local Texture Memory 307 MB
AGP Aperture Size 0 B
Driver File nv4_disp.dll
Driver Version 8.3.0.2
Driver Date 12-4-2005
Driver WHQL Certified true
Max Texture Width 4096 px
Max Texture Height 4096 px

 

Oh here are my scores from a previous post I made:
nvidia
3dmark03=4189
3dmark05=1887
3dmark06=791

intel
3dmark03=1461
3dmark05=533
3dmark06=137

 

Can You tell me please what resolution You used to get these scores?

 

Theres only one card. It also depends on what drivers you use. Some drivers don't enable turbocache which in my case, the reason why it doesnt show the 256mb.

ati mobile cards also work the same way. certain drivers have different effectrs when it comes to the hyper memory.

 

I just o/clocked and put the latest drivers on mine...downloading 3dmark05...

with default drivers and not overclocked I got 1939...so will post the latest marks in an hour or so.



@ foxy - the 3dmark software automatically sets it to your native resolution while doing the tests - so in SZ or FE's case its 1280x800.
