I have 8 RAM slots and 8 RAM chips

IN my CASE TWO CHIPS ARE ERRONEOUS --- 

faulty 2 chips or slots are the: 2, 4 --- i cleaned slots and chips and re-inserted but the problem persist

 

Remove completely chips in slots 2 and 4 ... or...?

sometimes shows during boot 

211 - Memory Warning Condition Detected Slot 2

but sometimes

203 Memory module failed self-test and failing rank was disabled Slot 4

 

If chips problematic must be removed from PC??   

// In BIOS see the post ^^^^ shows 8 x 4GB --- Ram but in windows 32GB -- Usable 24GB

 

in other words, according to:

 

https://support.hp.com/si-en/document/c01319077

 

leave blank 6/8 slots... ??? 

 

Required DIMM installation order

Use the following sequence as a guide for installing memory (see the following figure for socket location):

• Install a single DIMM configuration in socket 1.
• Install a two-DIMM configuration as a matched pairs in sockets 1/5.
• Install a four-DIMM configuration as two matched pairs in sockets 1/3, and 5/7.
• Install a six-DIMM configuration as three matched pairs in sockets 1/3, 5/7, and 2/4.
• Install an eight-DIMM configuration as four matched pairs in sockets 1/3, 5/7, 2/4, and 6/8.

My  advice is take all the ram stick out; then just try them one stick at a time in slot 1. 

That should flush out the damaged ram.

If it boots successfully for each one it could be faulty slots; so you nee to go to 2 slot config and four etc until it fails.

Also the RAM you have did you buy in 'Matched pairs' or are you mixing different  brands / unmatched pairs?

all 8 x 4GB sticks with one buy from ebay DDR2 ECC --- all from one seller

I have and 4x1GB may if problematic 2 sticks 

put 1GB

so having sticks

4 1 4 1 4 4 4 4 

? 

 

This is ok or 2 x  1GB sticks being in 6/8 slots???

[nigsy]

Mixing memory 1gb / 4gb is not an issue if they are in the right slots.

The issue is whether or not you have matched pairs. If you got them in sealed pairs off of eBay they should be fine as long as you keep them in their original pairs.

 

But all this is pointless if you haven't check each stick is working and all slots are working.

see here

shots from BIOS and Windows 10 --- detect 32GB usable 24GB...

 

So if all DDR2 slots working --- and having 2 sticks malfunction --- can place instead for the malfunctioning : 1GB x 2 sticks in 6/8 slots so having 26GB ...?

It should work.
