RE: [amibroker] OUT of MEMORY code

This program does not improve anything in your system. It just monitors the usage of pagefile in your system.

 

You need to follow the install instructions, and then when you shut down windows XP it will pop up a message
with usage of the pagefile during that session. At you option it will write/append to a text file which you later
can open to review history.

 

I have not noticed any penalty on performance, and, you can uninstall it after a time you are satisfied you
gatehred enough information.

I installed this program,  and ran programs that require 40 or more 6.13gb images open at the same time

With  the  XP_PageFileMon  program running it significantly slowed my computer processing time

 

In addition I noticed that when I had AB open to a stock it took a few seconds for today’s price to come up on the candle-stick chart.

 

To me this program did not make things better it made things much worse

Just what I found with my computer configuration and programs

I have seen some articles claiming that for large amount of RAM page file should not be increased.
(with very large RAM size you do not need to use any page file at all). Excessive page file actually
has a negative effect on performance (searching vast size of empty file takes longer).

 

There is a tiny freeware utility called XP Page File Monitor ( XP_PageFileMon.zip circa 2003)
that you should be able to find, it runs as a shut down script.

 

Once installed, it monitors your actual usage of page file and writes it to file on all windows shut downs.

You will be surprised at the results.

 

I have 2GB RAM and set the page file to 2GB which is about 4 times the maximum I ever saw during
2 months of monitoring.

Yep, not your installed memory.  I have 1.5Gb and AB runs fine.

 

Just a thought...  Try turning Off the code switch and then turning off HyperThreading (I think that's an option), then turn off both.

 

Also, have you checked your page file size?  At 2Gb of memory, it should be set to about 3Gb. 

 

I can't think of anything else.

 

Good luck,

 

Dan.

2gb of memory, think it is like 533 speed, Hyper thread machine,   plus I changed the Microsoft code switch to allow 3gb of memory and page memory is maxed out too

 

That is not the issue,  has to do with settings inside AB I would think

Mark,

 

AB and eSignal are memory "intensive".   With EOD data (i.e., no live datafeed), I've had AB use more than 1/2 Gb of memory after an exploration.

 

How much memory does your system have?  If less than 1Gb, consider upgrading.  

 

Regards,

 

Dan.

I am trying to run an explore on my whole data base now and am getting an out of memory though it says

E-signal out of memory and AB is locked up

 

Any suggestion?

 

Thank you

 

 

 

Mark
