Title: RAM Bam
Post by: Blunt on August 05, 2005, 05:21:50 PM
as mentioned on another thread, I've just purchased a juicy 1 gig RAM stick from Crucial...

I'm having some problems installing it.

I had 2x512mb in slots 1+2 so I just popped it into slot 3...
result: pc wouldn't boot

so I took it out and was back to normal.

then I stripped out all RAM and pc wouldn't boot

I put the 1gig into slot 1...pc booted up fine but seemed a bit sluggish

then I put a 512mb into slot 2....pc boots up but I'm given the option of starting in safe, normal, or last known good config...trouble is I can't choose because the keyboard won't work...I have to watch the 30 second countdown to start windows in normal mode...it then seems ok.

then i put the remaining 512 into slot 3....pc starts to boot then says I've no keyboard attatched...and stays at that point as I can't press f1 to continue or esc to quit


Motherboard Name   ECS KT600-A
Physical Memory:
      Total                                             1535 MB
      Used                                              481 MB
      Free                                              1053 MB

any ideas anyone?

what other info can I provide?

Is the old memory Crucial as well and what Mhz was the old memory running at?

Could be that the new memory is running at 400Mhz and your board is set to run at 333Mhz (ie) at set at 166 in the Bios and there is a conflict. Are the FSB jumpers on the board set at 333 or 400Mhz?. Check the settings in the Bios and the jumper and see if it needs to be changed and then if it will run.

If it doesn't like running at 400Mhz then set the jumper and Bios to run at 333 and you could compensate by setting the memory timings to 2.5 3 3.

From ECS website:

Memory

    * 3 x 184-pin DDR DIMM socket support up to 3 GB ( DDR400 up to 2 GB )
    * Support DDR400/333/266 2.5V DDR SDRAM

So sounds like there might be something funny in way slots are handled. My old Epox board allowed double sided or single sinded in Slot 1 but slot 2/3 was like a split slot where you could put double sided in one of them or single sided in both but not double sided in both)

I'll keep digging to see what I can find.

From manual:

DDR SDRAM memory module table:

DDR 266 - 3 DIMMs
DDR 333 - 3 DIMMs
DDR 400 - DDR 400 can only support up to 2 DIMMs:
1. One double-sided DIMM (or)
2. Two single-sided DIMMs
Note: We do not guarantee that all DDR 400 memory modules will work properly with your motherboard.

'scuse me cos i am a bit dimm :P

I'm not exactly sure where to look in BIOS or where to find the settings you mentioned...

can I view them in everest or do I have to hit del at startup? (I just did that but couldn't see anything I understood :blink:  and i didn't want to mess anything up)

this is part of everest report

Doesn't really tell us enough. The sisoft sandra motherboard info page would give us better info such as memory timings and CL status.

Can you remember what the memory sticks looked like when you fitted them. Did any have chips on both sides of board and did any have chips just on one side of board?

all 3 sticks have chips (if they're the black rectangular bits) on both sides...they look more or less identical...

Looks like tho old 512 isn't quite identical to the new 1Gb:

Quote1Gb Memory Timings:
   @ 200 MHz                    3.0-3-3-8 (CL-RCD-RP-RAS)
    @ 166 MHz                    2.5-3-3-7 (CL-RCD-RP-RAS)
   @ 133 MHz                    2.0-2-2-6 (CL-RCD-RP-RAS)

512Mb Memory Timings:
   @ 200 MHz                    3.0-3-3-8 (CL-RCD-RP-RAS)
   @ 200 MHz                    2.5-3-3-8 (CL-RCD-RP-RAS)
   @ 133 MHz                    2.0-2-2-6 (CL-RCD-RP-RAS)
I take it that the second entry for 200Mhz for the 512 module is an error and should read 166MHz.


Additionally:

Quoteall 3 sticks have chips (if they're the black rectangular bits) on both sides...they look more or less identical...
means that you have two double sided DIMMs installed but the manual says you can have 1 double sided or 2 single sided DIMMs on the board at DDR400 PC3200 rates (see my earlier post)

To overcome this you could try running the memory at PC2700 DDR333 (166MHz instead of 200MHz). To do this you would have to go into the BIOS and set the memory to NOT use the SPD method of timing detection and you can manually set a frequency of 166, CL2.5 and 3-3-8 for the other timings (RCD, RP and RAS)

I think I'll leave it for tonight and start afresh tomorrow...

Sorry Dingo M8 :blush:

I completely missed your post....I just kept tappin "last post" & you must've come in under the radar...

I'll answer the questions tomorrow as I've had it for tonight
 :closedeyes:

cz is ok though and thats what counts....i'm still crap btw :rolleyes:

my other 512 stick is crucial....should I swap it out?
QuoteI take it that the second entry for 200Mhz for the 512 module is an error and should read 166MHz.

it says 200 for me :huh:

Quotemeans that you have two double sided DIMMs installed but the manual says you can have 1 double sided or 2 single sided DIMMs on the board at DDR400 PC3200 rates (see my earlier post)
crucial scan said this was compatible RAM...well, they offered me 512 and I went for the next 1 up...but they said it was compatible

QuoteTo overcome this you could try running the memory at PC2700 DDR333 (166MHz instead of 200MHz).

Go into Bios, advanced, and look for config system

Should be some options for changing\setting FSB, ram settings, etc

Set the ram to 166Mhz (effective DDR at 333) and ensure the jumper on the mobo (refer to your mobo handbook) is also set at 166Mhz.

You may also get the chance to, after you have tried this, to alter your ram settings, again in advanced, from their presets to 2.5 3 3 8.


If that doesn't work then call BB on Edinburgh 5555 :D
