Ahhh.. this is more like it, a nice quiet morning with no parades.

OK.. then grab the memory chip number and we will put it to rest without question

I am fairly sure this is the ATi HM system at work but its always best to confirm so you know what you have.

If its 512 there is no reason to go any further as it is working correctly.

If we find the card is in fact a 1GB then we need to look at your motherboard and its BIOS and see what may be wrong there.. or possibly the video card BIOS. I know the Asus HD 4670 had a video BIOS update for it but that was to address a crossfire issue using two cards and certain motherboards... since that deals with 2 cards in a system it is possible that update may also affect the memory reported/used but I saw nothing that suggested the BIOS update had anything to do with that.

I do not suggest BIOS flashes of a motherboard or a video card unless absolutely necessary so lets get a look at the memory chips first.

Nvidia has been doing that .. similar system to ATi HM

But theirs is tied to the VISTA system of memory allocation so it is possible to not only see double, like with ATi HM, but more than double depending on the status of the system and physical memory installed and in use.

The reason his card is in question is because the amount is exact which is why it can be questionable. It is not uncommon as one may think to see a missboxed card or a video BIOS out of whack. If his was showing the same as yours I would then tie that to the same Vista allocation process however since it is exact there is still a chance he may have a 1GB card till it is physically confirmed.


with the Vista DX10 API you see another allocated block of memory which can increase the DXDiag reported amount further.


The reason I asked Mazza to check his properties is because they should show this which tells you the Vista sharing process is in use and how it is being used however with ATi HM this may not display as shown

I use XP

Matters not in your case because the reported amount is exactly 512 greater which is what makes this a bit more difficullt to call

That is their 16Mx32 GDDR3 512 as expected..

The card is 512MB, no doubt about it now


The secondary numbers tells me the max frequency for the chips is 1000MHz. How well they would run past is based on how well Asus made the circuit board and supporting voltage regulation system.

Since it would appear Asus is running them @ 2K (DDR) the card is already running at max so clocking the memory would be problematical in trial and error


At this point Mazza, I think what you are seeing is ATi Hypermemory in operation. It wil not hinder perf (or really help it either LOL )

But you do not have a 1GB card. The readouts may change with driver updates as that is what drives the feature, drivers

GPUz is telling you the truth
