The card comes with 512 or 1GB

http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=50001315+40000048+13...

It is possible the drivers are screwed up and reading it wrong.. or, they are a run of missboxed cards.

Heres the deal..

If there is some kind of glitch in the card it is possible it is reporting the wrong memory amount so even low level tools may not read it correctly

Try GPUz first http://www.techpowerup.com/downloads/SysInfo/GPU-Z/

check the memory amount

Another way to sleuth out the amount is look at the usage using MemStatus. FSX by default will try to consume 512MB during use if the card has at least 512.

If a user adds a bufferpool amount to their FSX.cfg file FSX will reserve that amount over and above 512 so a readout of memory use during FSX use with a (in example) 35MB Bufferpool reserve should show about 530MB used.

If it does not exceed 512 or FSX crashes then the card is 512 if it does exceed 512 and FSX runs, even with some graphic errors, then the card is 1GB

The tool may not work in Vista

If the BIOS of the card is reporting the wrong amount I dont care what tool is used to read the card.. DX or any other.. it will read incorrect.


However the thought of looking at the memory chips..  that is not a bad idea if the other checks do not define the amount however he may see either 4 or 8 modules if it is the 512/1GB Asus model but that also depends on the chip in use. I know the Hynix memory chips and it may not be 8 modules for 1GB

It could either be 8 of Hynix, 16Mx32 (code2) (512MB) with 4 showing on the back


Front



Back




or 16 of their 64MB x16 (code A)..  (8/8)

But its also possible they used their newer higher density chip in which case it could still be 4/4 and counting the chips on the back of the card wont tell you anything..

However to confirm what he could do is pull the card and post all the data off of one (1) of the Hynix memory chips (large flat black blocks on the back of the card) and from there it can be verified which density of the Hynix memory chips are in use and that would settle it for sure.

I have all their data sheets here.

I did not say it would not be of use to check .. what I said is if his Vcard BIOS is reporting the incorrect memory no Windows tool will show it correctly

how are you going to verify his Vcard or system BIOS? Have you looked at his system?

DX could say 512 and others say 1GB.. or the opposite,.. do you know why that could be?

I do

The chipset register of the system BIOS may not be working correctly with this card and that too can cause 1, 2 or even 3 different readouts to conflict.

The initial suggestion of using bufferpools and the tool I posted (drop to the desktop to check while FSX is running) would have resolved that without pulling the card. If he read above 512MB there is no question that the card has >512 because that tool reads the data sent from system memory to Vmem and bypasses the card and system BIOS which was one of the reasons it was not working in Vista when it was initially released and why it has a bug whereby >2GB of system memory caused incorrect values to display.

I verified the tool posted was corrected and updated for Vista use, something I was not aware of at the time of my initial post.

Regardless I said your suggestion of checking the chips is the most secure method of establishing the memory amount however I also said it needed a bit of refining so he did not assume something that was not true from the suggestion you made of counting chips. They need to be verified by ID number, not # of chips on the PCB

Although you may have some knowledge so far what I have seen is your suggestions are amateur at best Maverick and you have a lot to learn. 1/2 arse suggestions with a 'know it all' ego are dangerous.

no question?   none?

telling someone a 2.0 card will work flawlessly in a 1.0a slot without informing them of the possible/direct issues is irresponsible if you really do know what you are talking about. You did not even look at the MB involved in that inquiry.



Go back and read what I posted to you again. You had absolutely no basis for addressing me the way you have here other than what appears to be a childish ego problem.


Being this is the second time you have addressed me in such a way, http://www.simviation.com/cgi-bin/yabb2/YaBB.pl?num=1239891051/21#21 I am quite fed up with your immature attitude.

as far as I am concerned, this is our last communication







@ Mazza.. check the chips and I will pull the data sheets. Maverick was correct that is the best way to confirm however do not 'count' the chips, get the ID numbers off of one as that is the only way to define the memory amount without question.

The chip will be look like this





I need the long ID string stamped under: hynix

If you would include the batch code under that string I can use it to ID the run they came from which will also tell me what they may clock to

Although I get the joke that is really not necessary


There is no score involved here and this forum should not be considered a place of 'tech knowledge' competition however when I see incompetence with an attitude I do take notice and I will make sure it does not cause someone to make the same simplistic and costly mistakes the person soliciting such advice probably makes day in and day out.

Which is why this was posted at the top of this forum years ago

http://www.simviation.com/cgi-bin/yabb2/YaBB.pl?num=1165332791




It is the responsibility of the person reading these forums to take caution in what they read and not assume what they read is accurate, or, not assume what they read is complete with everything they need to know in one post. Not many people around here have the real credentials to give out secure CS advice.

But anyone giving out advice should also assume the responsibility of informing the person they are trying to help that they are not an expert and that there may be things they wish to check out further before taking steps that may end up being costly. ie; Suggest buying a mismatched PCIe protocol video card and insist that it will work without question and with a tone in the post that suggests the advice is from ‘knowledge and experience’ and then FURTHER compound the potential negative economic impact to the person looking for help by not asking what PSU is in the system before making such a purchase.

and then add insult to injury by suggesting someone needs to buy a CPU they already have

There is a difference between knowing what one is talking about and just talking.



We have not heard from Mazza yet so it is possible he made a mistake when reading his system. GPUz will display the same info DX Diag will display assuming the system BIOS is working correctly with the Vcard and GPUz will give him much more comprehensive information about his Vcard than DX Diag which is why I did not see a need to suggest it at this point in the discussion. Mavericks suggestion of looking at that GUI is fine however the suggestion it will tell the user definitively what they want to know, is wrong.


Many times I have seen the DX system installation corrupt and displaying inaccurate information so although it is something to check, look at it with caution if other tools/drivers are reporting something that may appear out of place, or, something completely different.





What I will not stand for and see all the time even from my annual assembly of PhD candidates is know-it-alls who think they can make suggestions for the purpose of competing in knowledge. This forum is not a competition.

I will tell everyone the same thing I tell them...  I am not going to play a silly ‘can you top this knowledge’ game with completely unarmed contestants.



....we now return to our regular program, already in progress

Different viewpoint?

lets review that...


You mean the viewpoint someone should buy a video card not designed for their motherboard slot and there is no question it will work?

You mean the viewpoint that counting the chips on the back of a video card will tell you how much memory it has?

You mean the viewpoint that looking at a DX readout or other tools will define the hardware installed when the box says different?

You mean the viewpoint that a multirail PSU is better in any way to a single?


and...

You mean the viewpoint someone needs to buy a processor they already have?







No rant Mav, just making sure everyone here understands your advice is very dangeous, at best


I suggest you stick to your studies and leave CS to people who know what they are talking about

I have not insuled you with a personal attack however at this point you have me

Lets try this again.. you are about 1 post away from being gone based on SimV rules. I suggest you make use of that post and keep it as far away from me as possible.
