Nvidia and fast writes

Hii, it seem then when running the sysinfo tool, the Fast writes on my nvidia is disable.
when running
cat /proc/driver/nvidia/agp/card
and
cat /proc/driver/nvidia/agp/host-bridge
it does say that my card support this mode, I have tried adding to my Xorg.conf the line under section "device"
Option "AGPFastWrite" "true"
and still nada, Can some one please help me out here?

EAD wrote:Yes I know not everyone have these, but every one with Nvidia new card has it:)
Any way, How did you know it? (adding these lines to modprobe)
Where can I read about it?
I've done it waay-back on my previous Slackware installation. modinfo nvidia gave me a hint how to do it. Now, there are guides for it:

It all depends on your specific hardware. I've never had problems with it.

Problem enabling Agp 8x and Fast write on a Msi Neo 2 Platinium mobo.

I bought, about 2-3 months ago this motherboard and I installed in it a Sapphire Radeon X800 XT Platinum Edition. The problem is that I can't set, in my BIOS, the AGP to 3.0 (4X/8X) because the PC , then, seems to act weirdly and give me all kind of problems. When I go in Start --> Run --> and I enter "dxdiag", all of my direct 3D options are disabled and I cannot set them to "ON" as the "Enable" button seems to be grayed out.
The only way I can run the PC stable with the video card and the motherboard is to set the AGP to 4X. That way, all of my Direct 3D options will be back.
When I set it to 8X, sometimes the computer will freeze, the screen may turn black randomly and doesn't re-open. In my games, the levels (like CoD or Unreal Tournament, All the BF Games) won't load, it simply will freeze on the load screen.
Is this problem due to some incompatibility between the Mobo and the graphic card???
Is there a way I can keep the PC stable when enabling the AGP 3.0 (4x/8x)?
Thanks.

I would run drivercleaner pro and reinstall all your drivers.
The problem start from Bios.He can not anaible AGP 8x, so this doesn't have to do with drivers.

Nvidia fast writes

Well, my problem is with a geforce fx 5600 on a amd64 running nvidia's 64bit driver i only get 2300fps with composite extension. I am using renderaccel and nvagp, but people tell me they seem to be getting twice that. So i was wondering if anyone knew how to force fast writes. My motherboard seems to support (checked the bios, sba and fast writes are enabled), the card seems to support it (check /proc/driver/nvidia/agp/card), but its still not enabled. sba seems to work according to /proc/driver/nvidia/agp/status, but fast writes is disabled. as you can tell i'm trying to squeeze as much out of this card as possible its overclock by 77mhz...

MSI 865PE-NEO2-FIS2R AGP Speed & fast writes

Does anyone know how to enable either or both of these items I have just purchased an ATI 9800 Radeon and my AGP speed is only 4X and fast writes are not enabled ?

First let me say thanks for your input.
From within my driver tab SMARTGART I have 2X, 4X, 8X it is set at 4X if I slide the slider to 8X it makes me reboot and it's still at 4X.
I Have a P4c 2.40 @ 3.0 Ghz
Thermalright SLK-947-U with a 92mm fan
Hercules All In Wonder 9800 SE softmodded drivers turning it into a 9800 Pro
OCZ PC4000 Dual Channel 4 x 256 MB CL3 DDR EL Memory @ 500Mhz
4x Maxtor 80GB Hard Drives
If I put the same card into my other computer with an AMD XP3200 on an Asus A7N8X it boots into windows by default at AGP 8X
Any ideas ? I know some motherboards I have had have this option in the bios.

MS-6380 and AGP Fast Writes?

Greeting All! :D
I have a K7T266 Pro (MS-6380) mobo and recently bought a Radeon 9700. After a clean install of WindowsXP and installing the newest drivers for everything I have a machine that runs stable, but I'm not getting quite the performance I was expecting. After a bit af tweaking I was able to get my framerates and 3DMark scores respectable, but I can't enable AGP Fast Write. Trying to enable AGP FW causes a complete system meltdown. My question is, does this motherboard support AGP FW and if so, does anyone with this mobo use it and how much does it increase performance?
Thanks,
Robb

I do use that MB w/ AGP FW enabled and my system remains stable under 98SE and Xp pro, however I'm only using a Ti200 nvidia based card. So drivers may be the problem as ATi is famous for their driver issues, keep in mind that card is fairly new and it usaully take ATi awhile to get everything together.

as some of u may be aware the 9600 family of cards are very picky about fast writes. In order to run games without lock ups/crashes i must enable fast writes. The problem is that when i do, i get corrupt text, lines around my cursors, video lag etc etc. I recently switch to a barton 2500 that is running a 1.87ghz at 133fsb, before i ran an 1800 that did not have any of these problems with fast write enabled. bios and xp recognixed it as a 2500+ and i have the ratio set to auto and memory set to HCLK. I tried varios drivers for the gfx card and all produced the same results. Also tried all combinations of bios fast write on gfx control panel off, on etc. any ideas?
TIA

pic of lines/box around cursor

fast write disabled = game willl lock, the 9600 family of cards are notorious for this, i was able to fix my corrupt text and cursor problem by moving the slider under troubleshooting in the ati panel down a notch. in game im still seeing some problems though, hopefully the game specific forums can give me some help. thiis is really annoying because the dam game ran fine with my 1800 i went to the 5.09 drivers on the reccomendation from another forumite.

MSI 645 ULTRA - DOES IT SUPPORT FAST WRITE -

MSI 645 ULTRA - DOES IT SUPPORT FAST WRITE -
coz i want to enable it so i can get higher 3dmarks score.
so i'm wondering if it supported but i think it doesnt but not sure.
k thx.

I am assuming here, that it is always on and that turning it off isnt a option via the less than robust bios' that MSI gives us. That being said, there is a utility called NVMax that allows you to switch it on and off as well as 2x/4x agp, assuming again, that you have a NVidia graphics card.
Try that Emazy, Im curious to see if you get lockups like I do when I check it off. For me at least, it appears to be on, but greyed out. Sisoft says that it is capable of fastwrites but not enabled.
As I mentioned before and as Assaf confirmed, the difference is negligeable and in most cases causes to instability.
I think Fast Writes was as big a hype as MMX was. :]

How to disable AGP Fast Write with MSI 875P Neo-FIS2R ??

How can I disable AGP Fast Write with the MSI 875P Neo-FIS2R ? I can't find an option for this in the BIOS !

You wont usually find this option in most MB BIOSES , as the only Option that SOME BIOSES Have is the Option to enable, disable SBA (Side Band Addressing) for the AGP Bus....In order for you to Disable or Enable the FW, You Must have the Option in your Vidio Drivers Controll Panel.....If you have a NVIDIA Card, you Must go to http://www.guru3d.com And Download the program "NVHardpage" and then Open the Program and you wil have the Choice to Enable these options and they will then appear in your Vidio driver CP >> "Activate "Coolbitts" (this is NVIDIAS Overclocking Utility) Activate "Harware Options", and then Activate "AGP Options" and finally Activate "Performance Options"........If you have a ATI Card then you must Download one of thier "Tweeking Utilities".......I will Post the Direct "Link" for NVHardpage in a Minute, just say yes to the Lic. Agree. and download......Here>> http://download.guru3d.com/nvhardpage/ ...........Sean REILLY875

Questions on Client Failver and Fast Failover

've few questions regarding Client Failover and Fast Faiolver of Oracle Database HA. Before I ask those questions I would like to explain my environment. Below are the details.
- We have two physical locations called 'ABC' and 'PQR'
- ABC is the primary site.
- PQR is the standby site.
- In ABC, we have Oracle RAC database (11.2.0.2) with two nodes.
- In PQR, we have a single server standalone database (11.2.0.2) with ASM. This is not a RAC.
- Data Guard has been configured between ABC and PQR and it is working as expected.
- Please note that we have a licence for Active Data Guard.
- We have Oracle Identity Management products at both ABC and PQR and they are going to use RAC database as a primary database which is in ABC.
- We did not configure Data Guard broker yet.
We want to achieve below goals:
Goal 1:
Whenever RAC primary goes down completely, standby database should become primary database AUTOMATICALLY and it should allow read/write operation.
I guess this is called 'Fast Failover'. Please let me know if I am wrong.
Questions :
- To make this happen, Do I need to configure Data Guard Broker so that standy database becomes primary when RAC goes down completely with planned or unplanned outage.
- Let's say RAC goes down completely, how long does Data Guard broker take to make standby db as Primary.
- What about the client/application who already connected to RAC.
- Let's standby DB has become as primary and after sometime if RAC comes back , Does data guard automatically changes the role of RAC to primary ?
Goal 2:
As I explained above, all Oracle IDM products and applications speak to RAC database they only know about RAC database which is primary.They are not aware of standby database.
- Whenever a client session is in progress with RAC primary database, if RAC goes down completely , we would like to expect client session should get transferred standby datbase without loosing session information . However before this happens, standby database should become primary becuase client session may perform write operations.
- Whenever a client is trying to connect to RAC prmary and assume RAC is completely down, we would like to expect client connections should get transferred to standby database.
However before this happens, standby database should become primary becuase client session may perform write operations.
As per my knowledge, above scenarios are called 'client failver'. Please let me know if I am wrong.
Questions:
1. Please throw some light to achieve above features.
2. As per my understanding, before client failover happens, fast failover should have already occured and standby should get switch to primary role. I guess all this happens through TIMEOUT parameters. What are those.
Could you please help ?
Thanks

Airdisk - SLOW read speed, but FAST write speed with Leopard 10.5.1?

I've been complaining for a while about my random problems with reading files from airdisk. My solution has always been to relaunch finder and re-mount the airdisk when it slows down.
I just noticed the speed cut down to and when looking at the activity monitor, it's fluctuating up and down and never seems to go past 1.5 to 2 MB/s.
HOWEVER, what I did just notice is that my write speed is consistently 3-4 MB/s with no fluctuation at all. Interference is not an issue, as I'm on N-only mode and in 5GHZ.
Is there anything I can do aside from waiting until 10.5.2? This does this issue in every AEBSn firmware. Thanks.

I experience the same problem (slow read: 2,8 MB/s, fast write: 6,3 MB/s) with my airdisk over a LAN-connection with 10.5.2. I atteched the USB-drive directly to my iMac and then it's the other way around: fast write, slow read (although considerably higher and normal throughtputs so drive is OK).
Anyone having some suggestions? The airdisk is formatted as HFS+ (GUID) with journalling on, Airport firmware 7.3.1 and the most recent updates installed.

MSI 645Ultra bios 1.9B1 with Fast-Writes option.

you can get it from here:
http://members.optusnet.com.au/boris_m/ms-6547-191.zip
Im using it btw.

nah not official... remember when i was complaining about this board that it doesnt support fast-write and stuffs.... well that complaint got the msi engineer going... assaf gave me this bios to test it out and i hooked boris with it also... so feel free to test it...
as for me it seems nothing so far... it just feels like they added option on the bios for it, nothing amazing really =D

Fast Writes Supported But Disabled

I've got a KT4 Ultra (without FISR) and a Radeon 9000 (without Pro).
I've got FastWrites enabled in my BIOS, but every program I use says that it is disabled.
I've tried some drivers and it's all the same.
I've also tried to enable it with smartgart and some tweak programs, but every time I reboot, it is disabled.
(I have to reboot every time I enable this if I want changes to take effect)
Why does it happen?
Do I have to flash my BIOS 8o ?
It's all another KT4 problem?
Maybe it's a Radeon 9000 problem?
By the way, I have the VIA 4.43 Drivers and the Radeon 6166 and 6193 drivers for XP.
Sorry for my english.

Hi,
Have you tried with PowerStrip?
Enabling AGP Fast Write is done by the display card itself. The BIOS actually "facilitates" the display card if it supports this feature.
You might want to contact your Radeon 9000 manufacturer to confirm on this.

MS-8851 no SBA or Fast Writes?

According to Powerstrip, my 8851 (GF3 Ti200) does not support side band addressing or fast writes, but my 8871 (GF4 4400) DOES. I checked with a video bios utility and in the 8851 both are disabled in the bios. Is there a way to enable these? Is there an updated video bios?
Thanks in advance.

I am surprised neither side band addressing nor fast writes are supported by this card. It is a fairly recent card, the Ti200.
Is there any way to enable these items on this card?
Thanks.
