I forgot to add that the best place to check this is to look at registers 58-60h.

Code: Select all

59-58h = Device 0 Offset 59-58 - DRAM MA Map Type
   60h = Device 0 Offset 60    – DRAM Type

The memory I tried is Hynix 3x256mb CL2

The ID of two is HYM71V32635HCT8P-K A AA and the other one
HYM71V32635HCT8P-K AA

The sticks are double sided 16 chips total.

strange? In the Hynix spec the 71 is supposed to designate 128mb ram, but these chips are marked up as 256mb and they are 256mb.

The board revision is 1.32 (Cache 1mb) and the bios is R2.36.

They should work as well...strange indeed!

Can your board pass Memtest with the modules installed?

@Donpedro

disabled all programs with tool supplied and still no joy. the board just refuses to go into windows with 512mb of memory.

Presume you have already checked the caps. Have you tried installing the "Unofficial Service Pack"? - I am assuming that it is WIN98-SE you are running here. 98 won't use more than 256 meg without the "Unofficial Service Pack"; but I've never heard of it not booting on account of too much ram; except where like I said some very early Super 7s were limited to 384 Meg. Anyway that is a long shot you could try.

The AX59Pro I have is revision 1.1 with 512K L2 cache. This shouldn't make any difference though. Strange... :?

It might, if his was a very early board,; and yours a much newer one.

System as follows. I am sure that there is nothing here that should be a problem.

K6-III+/400ACR @ 550 2.05V
AX59PRO Rev 1.23 (Bios Rev R2.36)
384mb (3x128mb) Hynix CL2 Dimms
Geforce 2 Ti 64mb
WD 20gb 5,400rpm HDD
Creative SB Live 5.1
Generic realtek network card
Ricoh CD/RW
235W PSU

Oh! and the opeating system is Windows ME

The 384 mb ram is stated as 3x128mb above, but if I install 1x256mb with a 128 mb stick everything works fine. So the dimms will accept 256mb sticks it is just that the system as a whole will not take 512mb or more in any combination and boot into Windows.

Do you think I should try a fresh install of Windows?
I know it sounds crazy but could it be a power supply issue?

Possibly the processor. You have probably used it successfully at this speed before in other boards, so it shouldn't be; but for what it is worth not all 400s will go that fast. Though why more ram should make a difference is beyond me. Another thing you could try, (sometimes helps) is blow out your ram slots w/ compressed air. Also try clearing the bios before you install the extra ram. Assuming the board posts and runs DOS ok with 768 meg installed, if clearing the bios doesn't help then maybe a reinstall is a good idea. Don't know anything about ME cause I don't have it and never have. Still it sounds like a software - bios issue rather than a hardware problem. If you have not already tried it definitely try clearing the bios before installing the ram.

I thought that I remembered seeing something about a WinMe system limit of 512MB for RAM. Just a quick search turned up this post http://experts.about.com/q/PC-hardware- ... Memory.htm.

If you do go with 512MB, look at this article on Me memory management http://aumha.org/win4/a/memmgmt.htm



I'll look some more later. I kinda skipped over WinMe, so not too much hands-on experience with it.

mmmh,

stedman, please try this tool. it covers much more places of autorun-entries. you can save the output and post it here or pm me the result.

I am still convinced that it is a software issue, not hardware.

A follow-up to my earlier post--see the linked document at Microsoft's site (http://support.microsoft.com/kb/q253912/) and note its comment about system boot problems with "large amounts of RAM". Maybe the vcache upper and lower limits could help.

Sylvan thanks for the tip. I will try it out at home tonight. By the way I think that I have got the AGP mapped out at 128MB so I might try just reducing this to 64mb first.

Tried to set vcache to max and min values and still no joy. reading the article states memory configurations over 512mb can cause problems not 512mb itself as I read it.

Put another 64mb into the memory giving 1x256 1x128 1x64 total 446mb.

This boots into windows ME fine.

This is a pig of a problem. I know windows me will take 512mb and more because I have this loaded onto other machines in the house.

Stedman. :cry:
