K7N2 Delta2 - Multi-Word DMA Mode 2

Well, I was having problems getting windows XP to access my Seagate SATA 120 Gig Hard Drive at anything other than Multi-Word DMA Mode 2. Finally figured out what I had to do. After messing with cables and SATA connections and generally mucking around for several days, I decided, just for giggles, to enable RAID.
Did not want to run RAID configuration but it worked. The listing in windows Device Manager now shows the drive as Ultra DMA Mode 6. When you enable RAID in BIOS make sure to go in and enable it for SATA as well (consult manual). When I rebooted it asked to hit F10 to set up RAID, this I ignored. Finished booting into windows and new hardware wizard started up. Inserted floppy disk (included in Motherboard bundle) with the NVIDIA raid drivers. That was all. I expect that if you are experiencing similar problems with ATA disks, it might work there too. Hmmm, maybe I will give that a try next!
I had sent a number of email to tech support and they never mentioned this, food for thought!

Another update just came in from MSI support;

Would you please follow the steps below to verify?
1. connect to the SATA HDD to SATA1 on the MB;
2. boot system up and enter BIOS, Load Optimized defaults; set Integrated PeripheralsàOnboard DeviceàSerial ATAàEnabled;Save&exit setup;
3. enter OS, go to Device Manager, expand IDE ATA/ATAPI Controllers, right click NVIDIA nForce2
SATA Controller and select Properties,choose Primary Channel,then check what transfer mode the SATA HDD works at. We suggest you capture the picture and send it to us. Thanks!
Well, since I was already connected to SATA1 I decided, why not. Maybe third time is a charm (installing the NVIDA drivers that is). So I downloaded the drivers from their link, installed, and rebooted. I now have NVidia MCPS2S Parallel ATA Controller (v2.6) and NVidia MCPS2S Serial ATA Compatible Controller (v2.6) in the device manager under "IDE ATA/ATAPI controllers".
When I checked the details of the Serial ATA controller the Seagate drive shows up as Serial ATA DMA for transfer mode. When I checked the Parallel controller my IDE drive shows up as Ultra DMA 5 - Ultra 100 for transfer mode. Looks like all is good now and as it should be.
NOTE: had to disable RAID on a reboot to get drive to show up in Windows...hmmm. It worked what can I say!
Thanks to the people at MSI support for convincing me to install the NVidia driver set again.
P.S. NVIDIA nForce2 System Drivers for MCP2S
God I like it when a plan comes together! Hooah!

K7N2 Delta2 Platinum - J10 / Safe Mode ?

I set my FSB too high and cannot get my system to post. I see plenty of references to the J10 jumper but I do not see that listed in my manual nor can I find it on my motherboard. PLEASE tell me this MB has a jumper for booting in safe mode - this is a new PC I'm setting up for a friend I've tried clearing the CMOS to no avail. System has been stable for days before this.

Wow, has it only been 3 weeks? Seems like months...in any case, I've now purchased for myself or others 3 MSI boards: 1 K8N Neo Platinum and 2 of the K7N2 Delta2 Platinums. Overall, I'm very happy with these boards. I ended up with 2 of the K7N2s because I decided to RMA the first one (to later be used to upgrade an older PC of mine) and needed another socket A board for a PC that I was putting together for a relative. The long and short of it is that the problem I've detailed in this thread is STILL a problem even after getting it back from MSI earlier today. As far as I can tell it's in the same condition I sent it to them in. The difference now is I have another of these boards that actually works and I can test my RAM, CPU, etc to make sure they are in fact working (which they are) - the name of this story is:
Please Help Me Fix My Damn Board So I Don't Have To RMA It Again
(aka Why the hell did they remove the J10 jumper from this board?)
I've tried...
different PSUs (antec neopower 480w, truepower 430w, some sort of cheap raidmax 450w)
any combination of components you can think of: ram/graphics/cpu only, 2 of those 3 only, 1 of
those 3 only, NOTHING installed on the board at all.
different RAM in different slots - have tried generic pc2100, kingston valueram, kingston hyperx Corsair cmx-1gig
clearing the CMOS, removing the battery, hitting the power button, unplugging the PSU (umm not in that order). I've even said a little voodoo prayer as I replace the JBAT jumper to it's original position.
i've taken the board out of the case (actually i never got it INTO the case today) to make sure it's not shorting somewhere.
no BIOS beeps at all, yes the speaker does work. the D-LED with at least the basic ram/graphics/cpu installed reads #1 green, all the rest red. After a CMOS reset it goes from #1 green, rest red, to #2 green, rest red, then back to #1 green, the rest red.
The only thing I haven't tried is using a CPU with a FSB of 100 - this is mentioned in a few older articles I googled when digging around for ideas. All I have is a couple of 3200+'s - both of which work in the good MB.
HELP...anyone?!? Thanks in advance.

R61 Second HDD Bay DMA mode

Hello,
I'm using R61 to which I've replaced the DVD drive with an UltraBay adapter and a Western Digital 320GB HDD to expand my data storage. Everything is OK but the second HDD runs in Multi-Word DMA mode 2.
I've done with both the latest Intel Chipset patch and Lenovo Max Storage patch on Windows Vista 32-bit. After those patches some SATA device drivers have changed to new ones, but ATA channel 0 controller runs still in Multi-Word DMA mode 2, which is a setting for ODD.
I know that the controller for the UltraBay is PATA controller, so the SATA HDD in my UltraBay is converted to PATA mode by converting chip in the UltraBay adapter. But what I'm curious about is why it doesn't run in ATA DMA mode 4 or 5 set for HDD.
After replacing ODD with a HDD in UltraBay, the ATA driver doesn't change the DMA mode from Multi-Word DMA mode 2 to ATA mode 4 or 5.
Anybody has the same problem or a solution to this?

I know this is an old thread, but did you ever find the solution for this? I have the same problem with my T61. I can't get my WD Black SATA drive to transfer at anything above Multi-Word DMA 2 (16MB/sec). It's incredibly annoying, and I can't seem to find much online about it.

Ultra DMA mode 6

OK, after numerous tries, I failed to boot from IDE3 with the moded bios 5.6 that let you use ide3 and ide4 as normal ide channels. Now don't even ask me question about that, I don't want to here anything related to this.
Now I have flashed again to the standard bios version 5.6. I have my DVD-RW master on IDE2 (Ultra DMA mode2 = 33.33MBps = optimal) and my CD-RW as slave (multi word DMA mode 2 = 16.6 MBps= optimal ). My hd is master on IDE1. In my bios it says my hd is running in PIO mode 4, in windows xp it says it's running in Ultra DMA mode 5 (which I assume is UDMA100= not optimal). Why can't a ATA133 certified motherboard and a ATA133 certified HD can't work at UDMA mode 6?
I'm getting nervous here, I want my hd in UDMA mode 6!!!!!!
Yes I use 80 wire cable. And my hd is alone on it's channel, nothing could stop it!
Is it XP? MSI? me?!?

Yes - the standard IDE ports are ATA-133/UDMA-6 compliant. I don't know how to make WIN-XP show them as UDMA-6 but I'm sure someone else will. It isn't really important however as current ATA-133 drives do not perform better than a good ATA-100 drive.

DVD running as Multiword DMA mode 2!

I noticed since upgrading to my new system that both my CDR and DVD drives have been very slow. I'm talking 1 minute to copy a 50MB file for example! They are both running on the same P-ATA channel, the CDR is master, DVD is slave. In the device manager it reports the CDR is running in "UDMA Mode 2", but the DVD is running in "Multi-word DMA Mode 2". I beleive this must be the reason its all so slow. This was not a clean XP install, I just carried my drive over from my old intel system.
Any ideas how I can get the DVD running in UDMA Mode 2?
Thanks

Can you think of another reason my optical drives have both gone horribly slow since I upgraded? :( I assume that installing the Intel inf files for this mobo would ensure that the correct drivers got used for the drives.

Setting IDE device to DMA mode?

Recently my DVD has been burning superslow. It takes 24 min to burn a full disc at 8x. It should be 8 min only! Then I saw that my Drive is in "PIO" mode in the hardware settings. I'm using WinXP Pro so in the device manager I tried looking in the IDE ATA/ATAPI controllers to change the DVDRW to DMA but it's already has "DMA if available" chosen.
I tried looking in the BIOS and DMA is set to "AUTO".
Anything else I can try? My MOBO is a MSI PM8M-V, VIA chipset...
DVD drive is a BenQ 8x (older one forgot model).
The only thing I can thing of is I updated the BIOS with MSI live but that was quite a while ago...
Anything else I may have missed that is not DMA related that is causing the slow burn? I'm just buring ISO images with Nero.

Quote
I tried looking in the BIOS and DMA is set to "AUTO".
Uninstall the IDE Channel in Device Manager on which the drive is installed (e.g. usually Secondary). Restart and enter BIOS, set UDMA for that channel/drive to Disable. Save and Exit BIOS.
Boot into Windows normally, allow the controller channel and drive to be reinstalled, then restart again. Enter BIOS, set UDMA back to Auto or Enable, Save and Exit BIOS.
Hopefully this will clear/reset the registry flag that is forcing the driver to disable DMA.
Also, leaving UDMA disabled in BIOS will still permit the drive to use DMA mode (Multi-Word DMA 2) as long as 'DMA if available' is selected in Device Manager, which is not as fast as UDMA, but hugely preferrable over PIO.

[NF2] K7N2 Delta2 DVD-R/W won't write in DMA mode

Experienced builder, just built a new system, and my DVD-R/W will not write with DMA turned on. It does with DMA turned off, but that takes 50 minutes for a single-layer DVD! Have exhausted myself searching here and googling for an answer. Here's the whole story, and thanks for reading:
I had two Socket-A systems with Gigabyte GA-7VTXE mainboards (VIA chipset), both running Windows 98SE, both with Sony DVD-R/W drives (one a DRU-530A SL, the other a DRU-800A DL) working perfectly using Nero 6 Ultra Edition. The mainboard died (bad capacitors) in the system with the DRU-800 DL drive, so I bought a new MSI K7N2 Delta2 mainboard, and a new Antec Silent Case with Antec SmartPower 350W supply to put it in. I moved the rest of the components over from the old system, including the DRU-800 drive, the AMD 2200+ CPU, the OCZ 512MB single stick, and the MSI GeForce 2. The CPU and RAM are near-new, having been recently installed, and thoroughly burned-in.
With the same Windows 98 SE and Nero 6 Ultra, everything is recongnized, and will burn with DMA off (and it took far too long troubleshooting just to discover that). But with DMA on, Nero begins the write process, does the lead-in, and then immediatly gives a "drive not ready" error.
Steps I've tried so far: tried a new, 80-conductor cable. Tried DVD-R/W drive as master and as slave, with and without the DVD-ROM drive, with proper jumper setting and cable positioning. Updated Nero to the final Ultra 6 revision. Updated the DVD-R/W drive firmware to latest. Did a fresh install of Windows 98 SE, twice, once applying the MSI mainboard drivers and once not, afterward installing only Nero. Went and bought a new DVD-R/W drive (LG 4167). In every case, the results were exactly the same: no go with DMA on, works (but unacceptably slow) with DMA off. The two hard drives and the DVD-ROM drive appear to work properly with DMA on. I downloaded the latest drivers from MSI, and they appear to be exactly the same as the ones on the CD which came with the mainboard. [Though I bought the board new retail, it is after all an older model, but the CD must be fairly recent.] It appears, though, that the mainboard drivers for Windows 98 SE do not include any IDE drivers (relying on MS IDE drivers?), only the XP MSI drivers include an IDE driver.
With two DVD-R/W drives displaying exactly the same problem, I don't think it is the drives. The system appears stable in all other regards, the temperatures are very good, and it just doesn't appear to be a CPU, RAM, or power-supply issue. I suspect either a mainboard/chipset/driver issue, but haven't been able to get any nearer a solution.
Any help would be greatly appreciated. If any further information is needed, please ask. For example, I can't say the exact revision of the mainboard, because it isn't shown on the MSI site! MSI shows only two K7N2 Delta2 boards: the Platinum, and the FSR. My board is neither of those, though it is almost identical to the Platinum, the only differences being that the board itself is red in colour (like the FSR), rather than the Platinum's blue, and that it does not have firewire. The board layout itself is exactly like the Platinum, including the chipset fan, connector placement, etc.
EDIT: Sorry for slight mis-information--the Delta2 board I have is not red in colour, I was thinking of my MSI 939 board (K8N Neo4 Platinum) which is red. The K7N2 board is actually the colour of the Platinum, and in fact appears to be identical in every way except the missing firewire connectors and has only one Gb ethernet connector (if I've read the Platinum specs right, it has two).

Good work you got things going! I was going to suggest a start disk, but wasn't sure of your intentions for XP.
Thanks, Fredrik .

Did you ever manage to do a repair install of 98, as I asked in one of the first posts ever? I can't quite remember for 98, but for ME you find a folder C://Windows/Options/Install that contains the necessary files. But you would still need the 98-disk I believe to get the reg. code.
No, sorry. I did fresh installs of Windows 98 SE more than once, both with and without drivers, updates, IE, DirectX, etc. With 98SE, I couldn't find an actual 'repair install' option. I think one would just do a fresh install over top of the existing install, and am not sure how that would be any different than the installs I've already done, but I can try it if you like?
Microsoft used to have an updated 98 Driver Library, but I can't find anywhere anymore to download it, so can't try that.
Intentions? Well, I just read in a MS Forum thread that MSI (or any?) nForce3/4 chipset boards, such as the K8N Neo4 Platinum I'll be building next, don't support Win9x, so I suppose I'll need to use XP for now. But, my real intention is to move to Linux !
EDIT: You know, I was just reading, again in MS forums, that 9x does not support drives over 128GB. You may have noticed that I have put a 160GB (decimal) drive on primary slave. In the former system (again, 98SE on socket A board), that 160GB drive was on a Promise PCI IDE controller card with it's own BIOS, and with the Promise driver installed in 98SE. This allows both 98SE, and even DOS 7.1, to see and use the full capacity of the drive, as a single partition, without problem; but, Windows Scandisk and Defrag don't work on it, of course. But, I've got two PATA 160GB drives, going into two different systems, and only one controller card. To make use of both large drives, I could A) buy another controller card, B) buy an available commercial 9x patch which does the same thing for 9x as the controller's driver, or C) just use XP for now, until getting moved over to Linux. So I'm thinking that more or less settles it. It's a real disappointment that the cause of the 98SE/nForce2 problem wasn't found, but I want to thank everyone for all the help you've given!

How to Create a Multi Word Keyword

How do you join a multi-word keyword so it is recognized as one keyword? i.e. If you want "New York", not "New" and "York." Do you put it in quotes? Isolate it with commas? Other?
Ocean View
Ocean Front
Over the Water
I try to do this in Library Mode, Keyword Creation box, I get 2 words.
Example, I type Los Angeles and get: Angeles, Los
Nothing I try works. I know it is common since I imported 200,000 images and I see lots of word combos used as keywords.
I read the manual, looked at tutorials, read an existing thread on this, can't find the simple answer.
I am about to start keywording my 200,000 images from the last 12 years, I need to learn this at the get go...
How to friends?

In my experience, the keyword entry boxes (for adding keywords), properly treat spaces as data.
You may need to adjust your preferences (Interface tab):
When searching for said keywords after entry: not so much - Lr treats spaces as delimiter, not data - not as part of the search term...
I use SpaceUrchin, some people use AnyFilter, for finding metadata with spaces in it.

My PlextorPX-708A won't run in DMA mode

My PlextorPX-708A won't run in DMA mode I've tried reinstalling it and this was also a fresh install of winXP with Service Pack1a, my other dvd dive which is made by shuttle and is older will run in DMA mode and PIO mode but the plextor DVd writer won't and when I use it in PIO mode music and videos play slow in it what is the problem, I have a MSI K7N2 Delta mobo and the two drives are hooked on the secondary IDE channel and I tried swapping both drives to slave or master What is the problem
Any help would be appreciated

Hi,
Bobby: When you are booting and the machine detects your HD's and CD-ROM's sometimes the firmware version is shown along with the drive's ID details, press "Pause" on the keyboard if you don't get time to read it!
Another way is to go Start>Settings>Control Panel> Double-click "System" then "Hardware" tab - then click "Device Manager" look for "DVD/CD-ROM Drives" in the list of hardware and then click on "+" on the left hand side - your CD-ROM drives should now be listed - right-click on the drive you want the info on, then down the menu to "Properties" then click on the "Details" tab - this should show you the "Device ID" and hopefully the firmware version. (my apologies for writing this step-by-step guide but I though I'd include it just in case)
Or another way is explained on Plextor's site here:

[SOLVED] K7N2 Delta2-LSR Everything works but OpenGL Apps.

Hello Folks.
Interesting problem I have never run into before. Recently upgraded to the K7N2 Delta2-LSR MB, and everything works great except for any opengl based application, which just crashes out. But first a list of the system specs, then a detailed explaination of everything I have done.
MB: K7N2 Delta2-LSR
BIOS: Award vB.6 (11.6)
CPU: AMD Athlon 1333Mhz (Don't know which core, sorry) 133MhzFSB x10
RAM: (2) 256M DDR266 (No brand name, Samsung memory chips)
(Dont have memory timings handy, but will get if needed. Using By SPD in bios)
Video: Chaintek GeForce 6600GT (nvidia gefore 6600gt chipset)
PSU: Logisys Computer PS 550A-BK 550w (+3.3v/30A +5v/38A +12v/25A)
HDD: IBM 20GB IDE (Can get full on model if needed)
Audio: Sound Blaster Audigy2 ZS Platiumn (removed during testing)
OS: Windows 2000 SP4 (Fresh Install, latest MSI MB drivers from support site)
Okay i think that is all the relavent system specs, if anyone needs more I will be happy to provide.
Software used to test:
Direct3D: Rose Online (game), dxdiag 3D tests
OpenGL: Doom3 (game), Luna (nVidia Demo), Nalu (nVidia Demo), Dusk (nVidia Demo), Windows OpenGL screen savers
The Issue: OpenGL application crash during startup, normally in the nvoglnt.dll file. System completely stable otherwise. Windows 2D applications work fine. Direct3D applications work fine. I am using the latest stable nvidia drivers 84.21. I have also tested with the following previous driver versions 81.85, 81.95, 81.98 and with the beta drivers 84.25, 84.43, 91.28, 91.31. During this test I also used a MSI 6600GT card from a known good working system. Putting the Chaintek in the working system, verified the card was good. It worked no problem. Putting the known good MSI card in place of the Chaintek in non-working system, OpenGL applications still crash. I believe at this point I have ruled out both video card and drivers as a culprit. I have a clean install of Win2K SP4 on the machine with latest MSI MB drivers. I have also tested with a clean install of WinXP upgraded to SP2, with latest MSI MB drivers, Same Result. The ram I have tryed in both Single and Dual channel modes. I have removed one stick and ran the system with just 256MB ram. I also swapped that stick with the other one per chance it was one of the ram sticks. Though they had been running fine previously for years in the system without incident until the MB upgrade. Also if I had bad ram I would expect to have general system instability across the board, not just opengl apps. As a last resort I hung the HDD off my known good working system, even though it has an ASUS nForce2 chipset MB. When it booted up, All applications ran fine. DIrect3d and OpenGL. At this point in the game I feel I have ruled out software and video drivers as the culprit.
I've never really run into a problem like this before and am beginning to suspect that something is wrong with the motherboard itself. I just wanted to bounce this issue off the brainpower here at the forums, before I contact the place I bought it from for an RMA.
So I guess this all boils down to is, has anyone else ever had this issue and resolved it? Or, does anyone have any other troubleshooting ideas I can try? Thank you for all your time and consideration in this matter.

BOSSKILLER,
I agree but first we need to get APIC enabled with a Fresh Install of WinXP.
Richard
yes APIC must be enabled and OS installed after it. my reply was add-on after yours.
Quote from: Kershoc on 09-June-06, 09:36:23
Richard,
The install is already on its way. The XP install has an option for a quick format, so it's not as long as if I did a full one (thank goodness). I've got a copy of memtest86 on one of my diag cd's around here. I'll go ahead and let that run overnight when I go to bed.
Bosskiller,
It is BIOS version B6 aka 11.6. It came on the board by default. I dont recall seeing an Nvidia/ATI speedup option, but it may be one of those hidden ones you have to press a series of hotkeys to see, so I will check. I will let you know more, once this reinstall is completed.
yes Nvidia/ATI speedup option is hidden("SHIFT+F2","ALT+F3")
"I'll go ahead and let that run overnight when I go to bed."
hmm not good idea, couse that will take alot of time which is no need really, make 20 passes on Test Number 5 only in memtest, then leave SP2004 or Prime95 (Large'FFTs in Blends).
But at all think there is not instability issues or you may have it but that is not couse the your problem. becouse instability is random, you are already running Direct3D base application and problems must exist there also if you have big instability, but that is not happend. if stress tests detected instability issues than will mean that you have more than one problem.

K7N2 Delta2-LSR doesn't POST

Hi there, sorry before if anyone had asked this question before,
I have a system
K7N2 Delta2-LSR
Sempron 2600+
Adata Vitesta 2x256Mb
Winfast A250LE TD Ti4200
PATA hard drive...
i just tried to oc this system,
before : Sempron 2600+ @1833MHz, fsb 166, ram timing auto, vcore default 1.5V
1st trial : FSB 185, ram timing auto, vcore 1.55V, POST success, but i didn't boot to OS, entering setup again, wanna try higher FSB
2nd trial : at FSB 188, ram timing auto (i only changed FSB and vcore), vcore still 1.55V, my system didn't POST...
I tried to clear cmos, by moved the jumper, but it still didn't POST. Anybody help me pliz, what problem did i face?
Thank's

Quote from: HenryW on 11-August-07, 00:27:10
Do you have the manual that came with the motherboard? What kind of RAM do you have ( PC2700-333Mhz or PC3200-400Mhz)? If you are going to be increasing FSB you should have PC3200.
You will need to set the jumper on J10 to pins 2-3 (safe mode) restart PC and reset BIOS to default settings. Next turn off PC & set J10 jumper back to pins 1-2.
Before attempting to overclock again come back here for advice.
Yup, i have ram, DDR 500, but i run it at fsb 166.
what i tried is FSB at 190 Vcore 1.7V (default 1.6V) ram timing 2-3-3-7 T1
but the cpu temp is 52C (on bios)... is this normal? i only use the stock cooling HSF...
at FSB 166, temp is 47C. But i touch the HSF, not so hot like that temp, is the sensor wrong?
Anyway, on the socket A, there is an electric ribbon (sorry, i don't know the name...i name it my self ), is that the sensor for the cpu temp?
"J10" is nothing on my MoBo, i use "insert" while pressing power button, it worked just the same like "J10" works...

K7N2 Delta2-LSR Fsb issues

Hello everyone, I have a 2700+ xp 333fsb @ 2.158ghz (fsb 166 x 13)
Running on a K7N2 Delta2-LSR. Preparing for a lanparty I decided to try and do a small OC, so i decided to Oc it to 200fsb x 11 (2.200 ghz) I saved and rebooted and now it will not post. I have tried all known methods of clearing the CMos, including removing the battery and clearing the cmos, waiting in times between that, unplugging and doing all that, but nothing worked. After reading other posts it seems this problem can be fixed by shorting the j10 or j11 jumper, neither of those jumpers is on my Mobo, if there is another way to reset the fsb, please help me!!
ps. All other hardware that is non essential has been removed, and all the hardware was working before, i made no hardware changes before the OC attempt. Please help before i leave for lan party! (Friday aug 6, at 6:00)
(Edit), yeah setting the fsb past 166 went over the 333 limit for my 2700+ xp. So how can i reset this?

As some of you will be aware there is no safe mode jumper J10 on the K7N2 Delta2 series of boards. This has been replaced by the "insert" key method as used by Abit and Epox. To start your board at its default settings following an unsuccessful overclocking attempt you need to do the following using a ps2 keyboard. Turn off your machine and disconnect from the mains or turn off the switch on the back of the power supply. Press the front panel power switch several times to discharge any charge remaining in the power supply capacitors. Reconnect the power by plugging into wall socket or turning on psu power switch. Press and hold down "insert" on the keyboard and press the case front panel power switch. If you are successful it should start the cpu and memory at 100Mhz FSB. If it does press "delete" to reenter the bios to change your settings to known safe settings. Good luck.

Labtech: K7N2 Delta2 Question?

Hi labtech,
I d/l the manual, and wondering if some of the recent booting/posting problems here have been caused by the CPU Interface set to Optimal instead of Aggressive, the latter opening up more FSB opportunities? As well, some may not have set CPU voltage high enough for their FSB wishes. Just some guesses.

Hi Xroyal. For best results with my K7N2 Delta2 Platinum I use manual settings and set cpu interface to aggressive when running my Barton XP2500+ at 200Mhz FSB (400Mhz DDR). The settings I use are as follows:-
High Performance Mode:Manual
Dynamic Overclocking:Disabled
CPU Voltage:1.7V (the default is 1.65V)
Memory Voltage:2.7V (auto)
AGP Voltage:1.5V
Adjust CPU Frequency: 200Mhz
Adjust CPU Ratio:CPU Default
CPU Interface:Aggressive
Adjust DRAM Frequency:Auto
Memory Timings:Manual-11,2,2,2.5 (equivalent to 8,2,2,2 if you have CAS 2.0 memory)
Adjust AGP Frequency:Default
Using the above settings with the B30 bios (I found the B40 bios unstable with my hardware) produce a memory speed of 1507Mb/sec according to a Memtest 86+ v 1.25 boot disk. This is equivalent to a DDR speed of 3000+Mb/sec which is where it should be for a Nforce2 Ultra400 motherboard with my hardware at 200Mhz FSB (400Mhz DDR) with dual channel enabled and cpu interface on aggressive. An Abit NF7-S revision 2.0 is 1511Mb/sec with the latest bios by way of comparison with the same settings. If CPU interface is disabled or set to optimal the score drops to just over 1400Mb/sec. The 3D Mark01 score with my Asus 9600XT with cpu interface on aggressive is 13467 with CATS 4.10. If the cpu interface is disabled or on optimal the score drops to 13124. You can still use Core Cell to overclock or to reduce overclocking within Windows using manual settings if you wish. Finally if you want to overclock this board I recommend checking under the north bridge heat sink to make sure thermal compound is present in sufficient quantity. Mine had only a tiny drop under there. I also fitted a heat sink on the south bridge as this can get very hot under load.

New K7N2 Delta2 Platinum crashes with new memory

I recently bought a new K7N2 Delta2 Platinum motherboard and 2 x 512MB DDR400 OCZ memory, and now my machine continually crashes.
I've tested the memory sticks individually using memtest, and there are no problems with the memory. However, when I was in touch with OCZ support, they mentioned that there is apparently a problem with the nForce2 chipset being able to handle new 2 x 512MB memory. I had my motherboard working successfully with old DDR400 memory (BH5-based), which I sold when I bought the new memory. I was pointed to this site by OCZ support:

Is this the case?
If so, I'm surprised to see that MSI (or any manufacturer with nForce2 chipsets) can claim up to 3GB support. Comments?
Apparently, one thing to try is 2T command rate, but I can't find where to set it in my BIOS. I heard that it's probably set to 1T by default on my board.
Can anyone suggest any other options?
I'm somewhat frustrated that I've bought a new board and pretty expensive memory, and now have an unstable system. It's also too late to return to the reseller.
Any help would be appreciated!
Thanks.
Stuart.

Did you also test them together? If not, do so. Then up voltage as suggested.
Do you have them in dual channel, i.e one green slot and one purple slot?

That is correct; it is set up for 1T and can not be changed.
Not true that nforce2 chipset has problems running 2x512MB but it is notoriously picky. Your board tends to under-volt the memory too so you may be OK after increasing the voltage.
You don't say what bios you are using but bosskiller's modded bios b.72c has produced good results and addresses memory issues.
