Hi,
The information won't help. We need to know the MODEL/PRODUCT of the machine.

648 max , testing base and extended memory

I dont see the thread i answered to one time that someone spoke of using ddr400 with 648 max or max-L board and they were getting testing base and extended memory error from the LED's. Well i just got the same error today and my system would not boot i cut the power to the PS. and turned it back on it would start to boot and hang i could barely get to the windows logo sometimes the vid card wouldnt even boot the logo to the screen. This is with an updated mobo that msi sent me that i had just put in , it seemed to run fine at first then this problem started occuring. The only difference i had in the setup from the previous outdated board was i had the mem in DIMM 3 and not DIMM 1, so i moved the memory back over to DIMM 3 and now the problem is gone. Just something for those of you with the same problem to try.
Oh and i forgot one more issue, i cannot set the dram speed in the bios manually i have ddr 333 it should be 167 mhz so i set it to 4/5 and the system will not boot at all i end up having to reset cmos. I called MSI about that and they told me to just have it set to SPD , I said i know that and im fine with leaving it that way but it should let me set it manually if i wanted to and that i wondered if that had anything to do with the random " testing base and extended memory " problem.

It was probably myt thread...
http://www.msi.com.tw/program/e_service/forum/viewindex.php?threadid=6204&boardid=10&styleid=1
Have done some testing with both DDR333 and DDR400 and my results are in the thread.
Right no I'm using my DDR400 as DDR333, manually set to 167MHz, using DIMM1, and havn't seen any problems. I'll try the DIMM3 to see if I get any changes.
And by the way.. I tried setting my DDR400 manually to 200MHz and it wouldn't boot at all. After a lot of ugly language I finally got it back to the BIOS....after a reset of the CMOS.
Seams like you should use SPD if you want to use the correct freq for your RAM.
Have you tested the new 1.3 BIOS?

K8N Neo2 boot problems, freezes at testing base and extended memory

I recently bought a motherboard/cpu combo and been having problems. I'll start with my system specs:
MSI K8N Neo 2
AMD 64 3000+ Rev E
XFX Geforce 6600GT
Corsair Valueselect 184-Pin DDR SDRAM Unbuffered DDR 400 , 4 512MB sticks
400W Powersupply
I ordered a mother/cpu combo along with other parts to build a new computer. Finally everything arrived a couple days ago and I started building. First I installed the mb, cpu, ram and vid card to make sure everything was working. When I started it up I got nothing. So I started messing around and dropped the ram down to only one stick and used the D-Bracket. I figured out the cpu had been dislodged during shipping, got it installed again and was able to boot up could get into the bios etc. I put back in my other three sticks of ram everything seems to be working. Next I hooked up the hd, cd/dvd etc. Tried to boot up and it freezes after listing the total memory. Looking at the D-Bracket it shows it freezes at Testing Base and Extended Memory. So I unplug everything back down to just cpu, ram and vid card to see if it still works. It freezes again at testing base and extended memory.
At this point I drop the ram back down to one stick. It boots up and I can get into the bios again. So I shut everything off and put back in the rest of the ram. Turn it on and it freezes at the same point. Hmm, drop it back down to one stick and I can make it through to the bios. Now I'm just frustrated and want to see if I can get my other components working and maybe windows installed then I'll come back to figuring this out. So I save and exit the bios, while it's rebooting again it freezes at the Testing base and extended memory.
After playing around with it some more over the past day here is what I've come to see. If I move one stick of ram around I can get past the testing extended memory to get into the bios or up to the point of needing a boot disk etc. If I reset or reboot it from this point it will freeze. If I just leave my computer alone and off for around 30 minutes I can start it up once then it will freeze. Now I'm just confused why it will intially start up as everything is ok but freeze if it resets. Everytime it freezes it will be at the Testing Base and Extended Memory.
Some things I have tried while talking to a friend about the problem is clearing the cmos and also putting in the ram settings in the bios. Neither seems to work. I've done a lot of searching on google and in this forum and haven't seen anyone talk about a problem like this so hopefully I'm not missing anything.
If there's anything else you guys need to know about my setup let me know. I also hope I wrote this all clearly because at this point I'm pretty frustrated.
Thanks!

Ok, newest update.
After clearing the cmos I put in a stick of ram. Everything loaded up ok and I went into the bios and entered the values (2.5-3-3-8) and 2.75V. To my amazement it didnt' lock up after saving and exiting and it made it through to the Disk Boot Failure etc. So I hit the reset button to see if it would go all the way through again and it froze again with D-Bracket LEDs showing the Testing base and extended. I turned off the case with the on off switch in the back and powered up again. It went right through in the past I'd have to wait. So it seemed like things were a little better.
So I put in a second stick of ram and it booted all the way through, tried to reset to see what would happen and it froze. Turned power on and off and it froze not making it anywhere. Tried that a few more times and it would always freeze right away making no progress.
Back down to one stick of ram and it works again where I can go into the bios, save and exit and it'll make it through a full boot up to Disk Boot Failure. Weird thing was once after just hitting the reset button it actually made it all the way through. So it seems to act differently almost everytime.
To me at least there doesn't seem to be a logical way I can think of what the problem could be.

Extended memory 50% free,but work process reach PRIV

hi,
many dialog work process reach PRIV mode though extended memory is 50% free.
profile parameters as below :
ztta/roll_first     1 MB
ztta/roll_extension     2GB
ztta/roll_area     6MB
abap/heap_area_dia     2GB
can anyone throw light ?

Hi Krishna,
In addition to the parameter you have mentioned check these parameter as well in the system.
A process going into PRIV means that either it has exhausted its quota of extended memory (ztta/roll_extension) or that the total extended memory (em/initial_size_MB) has been used up by other sessions.So increase these 2 parameter to start with and then tune others.
rdisp/ROLL_SHM                32768       8 kB Part of roll file in shared memory
rdisp/PG_SHM                  16384       8 kB Part of paging file in shared memory
rdisp/PG_LOCAL                150         8 kB Paging buffer per workprocess
em/initial_size_MB            61440       MB    Initial size of extended memory
em/blocksize_KB               4096        kB    Size of one extended memory block
em/address_space_MB           4096        MB    Address space reserved for ext. mem. (NT only)
ztta/roll_extension           2000000000 Byte Max. extended mem. per session (external mode)
abap/heap_area_total          64424500000 Byte Max. usable heap memory
abap/heaplimit                40000000    Byte Workprocess restart limit of heap memory
Also,consider setting rdisp/wppriv_max_no and rdisp/max_priv_time,so that system performance is not much impacted.

Is heap memory is particular for a workprocess?and extended memory too?

Is heap memory is particular for a workprocess?and extended memory too?
All the while I need to know is :is more than one workprocess can be in Priv mode?

Yes - heap is workprocess exclusive memory.
Extended memory is shared on the instance.
Yes - more than one WP can go to PRIV mode.

About extend memory used in ST02

Dear expert
Is there a way to know how extend memory is used in ST02
When system start,no user log on we can see:
SAP Memory      Curr.Use % CurUse[KB] MaxUse[KB]
Extended memory     1.95 122，880 208,800
But we can find ,after user log on,the extend memory wiill increased.
SAP Memory      Curr.Use % CurUse[KB] MaxUse[KB]
Extended memory     54.92 3,452,928 3,768,320
I checked sm04 and stad,no such large amout of memory used.
We can see the problem in Y55.
Is there any way to know how the extend memory is used?
Thank you very much for your help.
Best Regards,

Active Global Support - Technology
SAP Asia Pacific(GMT+8)

The value specifies the size of the roll area in bytes.The roll area is one of several memory areas from which the memory
requirements of user programs are satisfied.For technical reasons, approximately the first 250 KB of a user context is always
stored in the roll area, additional data
1) to the limit ztta/roll_first in the roll area, then
2) in extended memory, to the limit ztta/roll_extension    or, if extended memory is exhausted, then
3) in the roll area again, until the roll area is full, then
4) in the heap memory (PRIV mode), to the limit    abap/heap_area_dia or abap/heap_area_total or until    the address space or
the swap space is exhausted.
Tthe case of non-dialog work processes, the sequence 1) 3) 4) 2) applies. After this, terminations occur, with errors such as:
STORAGE_PARAMETERS_WRONG_SET or an error code that indicates a memory bottleneck.

64 GB memory
8 * 2 CPU
Our extended memory setting is
em/initial_size_MB = 8192
Now SAP Expert recommand us extend memory em/initial_size_MB to 20GB, then
how much the memory configuration in OS level has to be enlarged before change extended memory in application level ?
Thank you,
Hong

Extended memory, lack of

I have just upgrade my system, KT4 ultra 6590 BSR mobo,Athlon xp2400 and when I boot, the ram counter always shows 4096KB. I have tried it with 256 meg, 512 meg and up to 3 multiples of each, all of which work in my old computer. Same mobo. After thoe boot screen, the next screen says "windows NT requires at least 7 meg extended memory to run and you do not have sufficient" Something seems to be limiting the memory to 4096 KB. Any ideas.

Hi,
It looks like your board is damaged.
You better replace it.

Extended memory is virtual memory space or Real Memory ?

HI ,
I would like to know whether the extended memory is virtual memory or its real memory. What is the parameter used to set the usage of the real memory of the system and the virtual memory of the system ( I want to know with ref to UNIX environment), and also clear about the hep memory( virtual or real).
Thanks in Advance
Rajesh Babu

Hi, I hope this will help:
The virtual memory consist of physical memory and OS swap space. Virtual memory can be allocated by the SAP system.
In the virtual memory exist shared memory and local memory.
Your question was regarding extended memory. Extended memory (user context) exist in shared memory. Heap memory exist in local memory.

Insufficient extended memory?

I am trying to flash my bios - windows me startdisk but when i start the command from the virtual Ram drive it says insufficient extended memory. Should I expand the "extended memory" in some way and what to do to flash my bios
PS i read the forum topics already and also sent a message to tiresmoke but no help so far

I do noyt give private help as that does not help others.
It sounds like you have the Config.sys file fouled up in a DOS startup disl. Or you are trying to flash using a DOS program in Windows.
Personally my suggest is always to have Live Update create a Bios Flash Diskette. Not to have Live update to flash it for you though. Then use the diskette that was created to boot from. This way you get a disk that will work and that sets up a RAMdisk that you actually flash from.

Extended Memory....

Hi,
If our RAM is 20GB, OS SWAP is 40GB, and Extended Memory is 20GB.
Is Extended Memory going to use OS SWAP if there is not enough RAM available at that moment.
OR
Extended Memory always acquire memory from RAM and program dies if not enough memory available.
I could not find a very good explanation of it. Can anybody please clarify it.
I will appreciate it.
Thank you.
SC

Hi Sume,
To my knowledge, extended memory are always reserved in swap and do not use RAM.
Please check the following :

ST02: SAP Memory-- Extended Memory- Max.Use=In Memory

Hi SAP Guru's
O/S: AIX, D/B: DB2, R/3 4.7 (620 Kernal)
My production System show
ST02: SAP Memory--> Extended Memory->Max.Use=In Memory
SAP memory     Max. use (KB) || In memory (KB)
Extended Memory 8,388,608   ||    8,388,608
Plz. let me know in detail what action I have to take.
Thanks & Regards,

Hello Krishna,
Initially you had mentioned that max memory was greater than in memory. That was surpsrising. Now i think you have checked and changed that both are equal. This scenario is okie. We have this scenario on several of your production servers. where Max Memory=In memory. This will happen because certain process will need all the available memory. So need to really take action. Also you are pretty close to maximum limit 8.196 MB.
Please award points in case the answer solved your query.
Regards.
