KT4 dram timing control

Can any one post best dram settings?
sdram cas latency ?
row precharge time ?
ras pulse width ?
ras to cas delay ?
bank interleave ?
ddr dqs input delay ?
sdram burst lenght ?
sdram 1t command ?
fast command ?
fast r-2-r turnround ?

i would imagine thats different from vonfig to config.
you gonna have to try different settings and play for a few hours with some benchmarking software ,i have corsair xms3200c2 i find best results are 2,2,2,5,1t ,ultra , fast r2r on , bank thing 4 , ddrqs auto ,burst length 8
but thats cause i can :]

MSI 875P FISR - 'DRAM timing is too tightly so reload timing'

'DRAM timing is too tightly so reload timing'
I recently got this message upon bootup. I have an MSI 875 P and I have 2 Gigs of Kingston RAM. I am wondering what would cause this message to come up out of nowhere. I was had the DRAM Timing by SPD Enabled and since that didn't seem to work I disabled it. I set the CAS, RAS, and CAS to RAS to 3 - 3 - 3 respectivly as listed below on the manufacturers web page located at:
http://www.ec.kingston.com/ecom/configurator/partsinfo.asp?ktcpartno=KVR400X64C3AK2/2G
My Current Settings Are:
CAS# Latency - 3 Clocks
RAS# Precharge - 3 Clocks
RAS# to CAS# Delay - 3 Clocks
Precharge Delay - 8 Clocks
Burst Lenght - 4
DRAM Integrity Mode - Disabled
--MY RAM--
RAM: KVR400X64C3AK2/2Gl
Description: 2GB Kit 400MHz DDR PC3200 DIMM 3-3-3
Specifications: Standard 128M X 64 Non-ECC 400MHz 184-pin Unbuffered DIMM (SDRAM-DDR, 2.6V, CL3, Gold) (Datasheet)
--Motherboard Manual DRAM Info--
Configure DRAM Timing by SPD
Selects whether DRAM timing is controlled by the SPD (Serial Presence
Detect) EEPROM on the DRAM module. Setting to Enabled enables the
following fields automatically to be determined by BIOS based on the
configurations on the SPD. Selecting Disabled allows users to configure
these fields manually.
DRAM CAS# Latency
This controls the timing delay (in clock cycles) before SDRAM starts
a read command after receiving it. Settings: 2, 2.5 (clocks). 2 (clocks)
increases the system performance the most while 2.5 (clocks) provides
the most stable performance.
DRAM RAS# Precharge
This item controls the number of cycles for Row Address Strobe
(RAS) to be allowed to precharge. If insufficient time is allowed for
the RAS to accumulate its charge before DRAM refresh, refreshing
may be incomplete and DRAM may fail to retain data. This item applies
only when synchronous DRAM is installed in the system. Available
settings: 2 clocks, 3 clocks, 4 clocks.
DRAM RAS# to CAS# Delay
When DRAM is refreshed, both rows and columns are addressed
separately. This setup item allows you to determine the timing of the
transition from RAS (row address strobe) to CAS (column address
strobe). The less the clock cycles, the faster the DRAM performance.
Setting options: 2 clocks, 3 clocks, 4 clocks.
DRAM Precharge Delay
This setting controls the precharge delay, which determines the timing
delay for DRAM precharge. Settings: 5 clocks, 6 clocks, 7 clocks, 8
clocks.
DRAM Burst Length
This setting allows you to set the size of Burst-Length for DRAM.
Bursting feature is a technique that DRAM itself predicts the address
of the next memory location to be accessed after the first address is
accessed. To use the feature, you need to define the burst length,
which is the actual length of burst plus the starting address and
allows internal address counter to properly generate the next memory
location. The bigger the size, the faster the DRAM performance.
Available settings: 4, 8.
DRAM Integrity Mode
Select ECC (Error-Checking & Correcting Code) or Disabled according
to the type of DRAM installed.
I am wondering if something else could be interfearing with the ram such as the AGP slot/card or if this is strictly a RAM issue. I have not seen this message before. Are my current settings what they should be for this RAM? Should I be asking Kingston this instead of coming here?

Thanks for the response.
My current DDR Power Voltage is set to 2.70.
Do you think 2.75 would be better? I'm wondering why you suggest 2.7 or 2.75, now that I look at the RAM specs it actually says 2.6 as posted above. I am not trying to be a jerk, I am just curious and want to know more!
My AGP Power Voltage is set to 1.50. I have a BFG Geforce 6800 GT OC 256 MB. I'm wondering if changing this a bit might help my graphics card as well? Perhaps 1.55 or 1.60V?

DRAM timing too tightly - reload timing

Hi
I've been through all previous threads on this subject, but cannot find a solution suitable for myself.
I'd been using my pc without problems for several weeks until last night when it failed to boot up, hanging on the pre-BIOS screen. I rebooted and got the message "DRAM is too tightly so reload timing". It then hangs again when a key is pressed and I'm unable to boot in Safe Mode.
I've definitely not altered any settings and not overclocked, so can't see why this is suddenly happening.
Any ideas?

A couple days ago my computer starting doing the same thing. I am not at it currently so I can't get the required specs.
The first time I just started to transfer a CD onto my harddrive and my computer auto rebooted. Didn't see any odd messages so I just let it reboot. I restarted all apps I had running and started the CD transfer again and it rebooted. This time I saw the "Dram timing too tightly loaded" message in the bios. I went and checked my bios settings and they seemed to be ok. DRAM set to auto, DDR timing set to "By SPD" and DDR voltage 2.5V. I did bump the DDR voltage up to 2.7V but I am still getting the same message.
I tried changing all these setting to what other threads have been recommending but still didn't work.
CAS# Latency:
RAS# Precharge:
RAS to CAS Delay:
Precharge Delay:
Burst Length:
Before this started my computer has been running perfectly for months. I just don't understand how it can start flaking out all of a sudden since I have not done any changes. And the reboots don't seem to be consistent other then when I am running a lot of memory intensive apps.
Known system specs from memory
MSI 6728 Neo2-FiS2R i865PE

I will post all required information later today.

Regarding Timed Controlled Sync in smart synchronization

Hi,
The MI documentation says that Timed controlled sync is not supported with File I/O in smart synchronization.
Is there any difference between Timed COntrolled sync and timed two way synchronization which is performed using timed two way sync bos (T01)
If they are same, does it mean that any application using timed two way sync bos, should have a mobile database.
Regards
Raja Sekhar

Hi Raja ,
just refer this link also ..
http://help.sap.com/saphelp_nw04/helpdata/en/43/5d298f28616e47e10000000a422035/content.htm
using this help , we can change the parameters in the MobileEngine.config file , so that it support time controlled synchronization.
Time Controlled Synchronization
Synchronization start automatically at a defined time interval as a background job.
i think file system is not so secure and not so easy to retrieve the data . there are chances for errors diring synchronization .If one error happens , that can damage the file system data base .
so in general , replace the file system with database (DB2E or MaxDB ) is the best option.
In the case of databases like DB2E , we can even administrate the database using proper GUI administrators ..

[865PE/G Neo2 Series] DRAM Timing is too tightly, Press any key to reset DRAM timing

hello,
i need some help.
I have been using this system for 1 year and 4 months now. A few days ago, when I booted up my computer, the message "DRAM timing is too tightly. Press any key or DEL to reset DRAM timing." appeared before it started detecting hard drive and CD-ROMS. I pressed a key and the computer continued as normal.
This morning, the problem got worse. I started my PC but my screen remained blank. The HDD light and CD-ROM light came on but the power light remained off. I turned off the PC by holding the power switch. When i turned it on again, it was the same situation but the power light started blinking. I turned off the PSU power from my wall socket and waitied about 1 minute. I turned it on again and the power light started blinking again but slower this time. I repeated the on/off steps by using the power button 2-3times. Finally, I tried pressing a few keys on my keyboard and the power light stopped blinking and remained green. I turned the PC on/off again and this time, it succeded in booting up.
And the DRAM messge appeared again.
I was like trying to start a car on a cold day... only after turning the key a few times did the engine start....
I've no idea what is happening here.
My specs are:
Intel P4 3.0C GHZ L2 512KB, FSB 800MHZ, 478 PIN
2x PC400 512MB DDR CL2.5
865PE Neo2-PLS

hi,
i smelled a burning smell from my power supply. i am replacing my power supply. i don't know if it was the cause of the dram timing thing.
i'll post here again after i replace my power supply. Thanks!!

When the comp boots up: press the 'delete' key to enter BIOS
Move the marker to 'Advanced Chipset Features' and press enter
Set 'Configure SDRAM Timing by SPD' setting to [Enabled] and press enter press enter
Press F10, and you woulg get the question 'Save changes and EXIT?', Answer 'YES* and press enter.

.Mac slideshow timing control.

AJAX slideshow with its snazzy look, but lack of timing control made it a poor implementation. I had cracked it. Here is the procedure:
1. Download: http://hac.95mb.com/dotMac/Arts_files/KBDIF.js
2. Put KBDIF.js in the same folder as slideshow.html --> typically: Photos_files folder
3. Edit slideshow.html
3a. open it with TextEdit
3b. search for 'slideshow.js'
3c. insert:
<script src="KBDIF.js" type="text/javascript"></script>
just below:
<script src="http://www.mac.com/1/slideshow/scripts/slideshow.js" type="text/javascript"></script>
so it looks like:
<script src="http://www.mac.com/1/slideshow/scripts/slideshow.js" type="text/javascript"></script>
<script src="KBDIF.js" type="text/javascript"></script>
That's it, you just added timing control. Keyboard inputs:
1 - 9 = number of seconds delay between slide.
0 = 10 seconds delay
Note: When AJAX slideshow first starts up, there is a 10-15 seconds delay for the slides and thumbnails to be loaded. I can't control that, unless I hack a lot more of AJAX js.
And default delay is 5 seconds.
Demo here, click Start Slideshow button:
http://hac.95mb.com/dotMac/Arts.html

I just uploaded new AJAX Slideshow converter to my host, and can be found here: http://hac.95mb.com/iWeb.html
This is for non .Mac server - or Publish to a Folder - method.
.Mac users will have apply the changes manually, sorry, my script magic couldn't work through iDisk (WebDAV protocol).

Timing control signal and data acquisition

I have a series of relays which when activated will close different elements of a circuit and I also have a sourcemeter(Keithley) sending a constant source current and reaing the voltage back.(But when no relays are closed the circuit is open and no source current flows )
I have a microcontroller(pgmmed for 9600 baud rate) based hardware circuit which closes different relays sequentially based on the input it recieves from labview pgm passed on through a Rs232 cable(9600/8 bit/no flow control)
So i made a sequence structure of sending signal to microcontroller signal then wait for the signal transmission and realy activation and then read the voltage value form keithley sourcemeter back to labview thro a GPIB cable.
These three events are reapeated sequentially in a while loop.
A schematic picture is attached.
BUt the problem I ma facing is the maximum speed of reading is limited to 200msec/reading even thought the relay activation time is as low as 30 msec.
I tried with many different delay times (140-60 msec...but more or less each reading takes up 200msec irrespective of the delay time..)
What could be the bottle neck is it the Rs232 setting at 9600 baud rate..can changing that to higher baud rate/including flow control solve this problem?

Find attached the picture of the vi where I tried to put in timers.one in each of the frame and at the end added one more frame just to measure the time elapsed .
The last frame and the frame with sourcemeter measurment show adifference of about 140 msec.
Is there any way to improve the speed of this portion?
Probably not. It sounds like the Keithly VI is taking 140 msec. You can try opening that up to see if there is anything in there that could be causing an unnecessary slowdown. But trying to tighten it up too much may cause occasional errors (such as timeouts) in trying to get a response back.
But surprisingly I tried displaying the actual timer value at the start and at the start of sourcemeter read function ..but the display of both indicators is almost equal with little difference of only 10 msec.????? I'm not sure which of the several timers you are referring to here. What is the value going into the wait function between the VISA write and the Keithly VI?
When you do benchmarking, the timer functions should be in a frame all by themselves. Having it mixed with another function or VI causes a bit of uncertainty as to when the time was taken. For instance, you dont' really know if the Keithly VI was started before the time was taken or after. (The time was probably taken first, but without a data flow or sequence structure dependency, you can't be sure.)

Timing control

Hello,
I need to acquire data from a powermeter every 2 milliseconds,how can i create a simple loop that can control the time and start the measurement?
Thanks in advance.

Hi Michael,
Here is a simple example for reading values from a field point RTD module and a DO module (since that's what I used). You may need to modify it somehow to suit your application. The start and stop switch is not really useful in this case because you can simply set your loop to continuously run mode and it will never stop. If you want to use this switch to start and stop your measurement, you may consider adding another while loop outside of this loop. Hope this will help you get started.

Msi kt4 ultra bsr

hi,
i'm new at this forum.
i have buy a msi kt4 ultra bsr board whit amd xp 2200 cpu.
twinmoss pc 3200 memory @ 256mb.
after install the hardware it seems to run only at xp 1500 in the bios.(amibios).
normaly you can set the range on 100mhz or 133mhz.
by this board we can set it only @100mhz and not at 133mhz.
have olso tryed whit pc 2100 / pc 2700 @133mhz.
still the same probleem,no 133mhz possible.
when i put the memory in my msi kt7pro2-ru board it runs at 133mhz only the pc3200 can run on that board.
is it possible that a little bug in the ami bios the problem is?
have look at the msi website for a patch but nothing.
have someone had the same problem.
regards jupliner / belgyium

hi,
still the same problem
today i have olso buyed the xp 2000+ cpu.
put it in the bord and haved here olso the same problem.
in the bios hey run at xp 1250 mhz and not xp2000.
have buy olso a new psu it's now 450w.
olso buyed new ram from apacer pc 2700.
we have tryed everthing in the bios to put it on 133mhz.
in the bios isn't not possible to set 100mhz to 133mhz.
when we change the fsb clock higher than we need to reset the bios.
in the dram timing control we can not set the 100mhz to 133mhz.
the current host clock is 100mhz and not changeble.
regards jup

Bad RAM?

Over the weekend I tried to compile Mozilla (on OS/2 if that matters) and got a few strange segmentation faults that I didn't have the last time I had tried. I then tried to check my RAM overnight, and indeed memtest86 v3.0 reported 39 errors total after 11 runs and more than 6 hours. But only in runs 5 (38 errors) and run 6 (1 error). Another check for 4 hours today did not give any errors...
Hmm, is there any way to check that it is indeed the RAM that's bad and not perhaps the board or wrong BIOS settings?
The settings I have are
+ DRAM Timing Control
System Performance: Ultra
SDRAM Timing: SPD
SDRAM Frequency: Auto
SDRAM Burst Length: 8 QW
SDRAM 1T Command: Enabled
Fast Command: Fast (the system does not boot with Ultra)
Fast R-2-R Turnaround: Enabled
+ Frequency/Voltage control
CPU FSB Clock 200 MHz
(Everything else under Frequency/Voltage control is Auto)
Anything not right for my hardware? I did not mean to overclock...
I have Kingston RAM and they give lifetime warranty, so getting a new one should not be expensive if it is really broken. But how sure can I be that Kingston accepts my memtest result?
And btw, does anyone have a contact number/address of Kingston in the UK? Or do I have to go through the shop where I ordered the RAM?
Cheers,
Peter.
Hardware:
MSI KT6 Delta LSR
Athlon XP 3000+ (FSB400)

OK, I got a similar reply from Boris at Kingston tech support. He also recommended against Ultra settings and also 2.5-3-3-8 (CAS latency (CL) - RAS to CAS delay
(tRCD) - RAS active precharge (tRP) - Active precharge delay (tRAS)).
In the BIOS settings I only found "CAS latency (CL)" and "RAS to CAS delay", so my settings are now
System Performance: Turbo
Configure SDRAM Timing by: User
SDRAM Frequency: Auto
SDRAM CAS# Latency: 2.5
Row Precharge Time: Auto
RAS Pulse Width: Auto
RAS to CAS Delay: 3
[* ]Write Recovery Cycle: Auto
[* ]Bank Interleave: Auto
SDRAM Burst Length: 8 QW
SDRAM 1T Command: Enabled
Fast Command: Fast (the system does not boot with Ultra)
Fast R-2-R Turnaround: Enabled
and the system seems very stable now.

You get the most significant memory boost from these 2 settings
Row Precharge from 3 down to 2 achieves +80MB/Sec boost
RAStoCAS Delay from 3 down to 2 will give you another +80MB/sec boost
(In the MEMTEST86 DRAM speed (top left))
You also receive 1000's of errors if the ram cannot handle that "2" setting.
Thanks for the tip, I will try it when I have time to reboot...
But in the meantime I hope "Auto" sets what is best for the RAM, I have no way to check. A full Mozilla compile is still only around 35 Minutes, that is OK for me as long as it works, whatever the actual settings are, and although Memtest only reports 754 MB/s for Memory...

KT6 and Samsung Memory...

Hello,
i am french sorry for my english.
I have
KT6 delta FISR
AMD 2600+ Barton (blocked for CPU ratio)
And 512 Mo Samsung pc3200
But if put my FSB over 170, my pc is blocked on testing memory bios
In my bios in DRAM timing Control, what modofications to do ?
Sdram frequency
SRAM cas latency
Row precharge time
RAS Pulse width
RAS to cas delay
For haven't no bug ?
Thank you

It's better to run the CPU and memory ratio at the same speed for AMD Athon XP's...
If your CPU multiplier is locked then you should up your CPU FSB and up your CPU voltage to supply enough power to the CPU. Keep the memory FSB insync with the CPU FSB...
You'll need to make sure you have a good heatsink when doing so, you could easily fry your CPU...

Sempron 2600+ recognised as Athlon 1100 on KT4V

I have a Sempron 2600+ cpu on a KT4V mainboard. At first the cpu was recognised as a Athlon 1700, so i updated the bios to last version (http://us-download.msi.com.tw/support/bos_exe/mbd_bios/6712v1C.zip). But now it's recognised as a Athlon 1100!
Anyone who knows how to fix this problem? All help is welcome...

Hello,
Sorry I should have checked the manual.
It does not have this option.
But
In the BIOS goto Frequency/voltage control and try the following.
Spread spectrum = Disable
CPU FSB clock = 166
Then go to advanced chipset features >DRAM timing control
SDRAM frequency = 266Mhz.
Save and exit
Anything?

FSB 133 SOLUTION REACHED!

I was able to successfully overclock my AMD Duron 800 to 866. My settings are as follows:
1) Reloaded default BIOS settings
2) Enabled 32-bit transfer modes
3) Disabled System BIOS Cacheable
4) Disabled C000,32k Shadow
5) Configured SDRAM Timing by User
6) Set SDRAM Frequency to HCLK
7) Set SDRAM Bank Interleave to 4-Way
8) Set PCI Latency Timer to 64
9) Enabled PCI IDE Busmaster
10) Set CPU FSB Clock to 133
11) Set CPU Ratio to 6.5
12) Set CPU Vcore to 1.70
13) Set DDR Voltage to 2.6
I have CONFIRMED that DRAM Timing Control is the root cause of intermittant stability issues related to this mainboard. I'm assuming that I should be able to run my AMD Athlon XP 1800+ at full speed from now on.

Well, I didn't want to take off the heatsink just yet, but I may have to any way.. But AMD doesn't make an athlon xp 2100+ with a 200mhz bus or a 333mhz bus.. the 333's start at 2600+ I think.. But I'll start a new thread.. sorry bout that
