...show us what it says under Memory and SPD?

This program has the ability to access the I2C bus directly and read the EEPROMs on the modules.

Will do

Duh, easy.

Make sure the ram module is properly plugged in.

If you think it is, and the computer still tells you it only has 2 GB then you have to investigate.

Take out the memory modules, put one at a time in the slot and see what the computer says. If the computer doesn't start with one of the modules, try the module in another slot. Try all four slots.
If a module worked before but this module doesn't work in any slot, it's probably dead or the contacts are burned out or oxydated. Get some isopropyl alcohol and a paper towel or something, wet the towel and rub the gold contacts of the memory. Dry it out, then try the memory again in all slots. Still not working? It's dead, Jim.

If both modules work separately (only one put in pc in the first slot or a particular slot), but you don't see in bios 4 GB or the value you're supposed to see when you put both modules in pc, change the slot of the second memory you add, try each slot.

If it works in another slot, the slot may be dirty or the clips are loose, or the ram contacts are dirty and the ram module slots may also be a bit dirty so a connection just happens to be poor enough to make your module not work. With the computer turned off, blow some air inside the memory slot, clean the ram contacts as described above, try again.

Motherboard should work with the ram modules in any slot you want, but for optimum speed it's recommended to put them as it says in manual 1-3 or 2-4 or 1-2, 3-4 whichever is the dual channel layout.

ChrisGreece52 · « **Reply #29 on:** April 21, 2013, 01:36:17 pm »

Thats the thing i tried all of thes combinations and the only thing i got from it is that every contact works and every ram module is fine.
When i unplug even one a buzer (atached to my motherboard (not soldered just hooked up)) came off i tried different combinations but the end result was the same.
If a ram card was missing from one of the 2 slots 1-3-2-4 (3 and 4 are the currenlty used card slots) the buzzer came off .... another thing i that i dont know why the buzzer came off even when i left one ram card inside (because bios only recognize one card i thought removing the one that isnt used by bios it would not affect the system) and i am a bit confused.

GEuser · « **Reply #30 on:** April 21, 2013, 02:18:22 pm »

Why not now take the opportunity to get some new ram?
Try a matched pair at 8gb since you have installed 64bit , its cheap enough on epay , in most games I have only seen just over 4gb used out of 8 so far and that's with no page file and 1.2gb for win7 included (the S.T.A.L.K.E.R. series) .

If the known stick(ram) works in all slots and then you try the other and no good suggests its crook or incompatible imo , so bin it and try a upgrade imo ..

Good luck

what do you mean the buzzer came off? btw seems like 1 of the modules are dead or 1 of the slots or the memory controller dying

what do you mean the buzzer came off

I presume he meant "went off" - i.e made a noise. Usually the BIOS will beep when there's a memory fault or no RAM.

Assuming that the motherboard is a Gigabyte GA-P55M-UD2 as per the valid.cardandpc.com link then the DIMM sockets are colour coded to show how they pair up. If you have one DIMM it should go in one of the white sockets. If you have two then they also should be in the white sockets. Any other combination either won't work or won't work optimally.

I would go into the BIOS and use the "load fail safe defaults" option to turn off any overclocking or tweaks you might have tried, then try each DIMM in socket 3 (white socket furthest from the CPU). If they each work OK in that socket then put the DIMMs in the two white sockets and see if both are now correctly recognised.

Apologies if you have already tried this.

My motherboard has a buzzer attached on it so when something is wrong with the ram or motherboard it buzzes.

The fun of the English language

Come (came) and go (went) are very similar, but "went off" means the buzzer made a noise while "came off" means the buzzer became detached from the board.

Yeah i meant went off..... i am sorry for that because came off ... sounded a bit wierd .... any way i apologise for my english and i loaded fail safe defaults and will try the slot now.

Thanks for the explanation Ian

i got the proficiency level degree in English language (highest degree you can get here in Greece) but some things will hunt me down forever

No need to apologize. But by conversing on boards like this you can learn English better and better!

Well i hope so because i dont want to lose my english skill due to the lack of use.I speak Greek as an everyday language but when we joke around with my friends we chat in english (everyday english but still english).Also the internet helped me a LOT with my english.

ChrisGreece52 · « **Reply #39 on:** April 21, 2013, 08:26:29 pm »

Well back on the topic ... i tried removing the card that was attached to the furthest slot from the CPU but nothing the buzzer WENT (and again thanks for the correction) off ... but well damn me !!! i removed the card from the furthest slot and left the other card (into the other white slot) attached .... it works and the ram configurations is like NoRam-Ram-NoRam-NoRam

ChrisGreece52 · « **Reply #40 on:** April 21, 2013, 08:27:24 pm »

I will try installing the other card into another slot (one of the blue ones)
0-1-1-0
0=No Ram
1= Ram

M. András · « **Reply #41 on:** April 21, 2013, 08:36:40 pm »

you can try to reset the cmos too, switch off the psu or pull the plug out of it and move the jumper to the other position for 10 secs or remove the battery, i dont know if the different boards have different error beeps or not, but when its only a short beep and then the POST screen shows up its fine, i never had a board or rams which had this fault

ChrisGreece52 · « **Reply #42 on:** April 21, 2013, 08:40:55 pm »

Thanks for your answer
the good thing is that my ram sticks are fine i tried both to a working card slot the second from the cpu
1-2-3-4 (i tried my sticks to the second slot)
when i installed one at a time to that slot the pc booted just normally
the bad thing is that my 4th slot (the furthest from the cpu or 1-2-3-4 the slot 4 in this example) does not work at all.

But i get in bios that my ram is still 2048 and at windows i get that the ram is 4gb but only 2 gb is usable.

The slot order from nearest to furthest from the CPU is 2-1-4-3, you're supposed to fill the odd (white) ones first, then the even ones. I don't think it matters whether you put a single DIMM in slot 1 or slot 3. Probably, if you had three DIMMS it wouldn't matter whether the third went in slot 2 or slot 4 though the manual doesn't mention how you're supposed to fill the sockets if you have three DIMMs.

filling a while and blue slot might work but you won;t get any performance increase.

That's actually slot 3 but it not working is a bit of a pain.

If you put the two DIMMs in the slots closest the processor what happens?

Examine the socket carefully - any bent pins?

ChrisGreece52 · « **Reply #45 on:** April 21, 2013, 08:55:12 pm »

Ok i inspected the pins all of them carefully under a strong light!!! NONE pins were found bent
i will try changing the ram position i also have the graphics card blocking the ram slot ill send a pic later

ChrisGreece52 · « **Reply #46 on:** April 21, 2013, 08:59:33 pm »

i got the cards installed in the two slots closest to the cpu (blue and white ones) and bios say that i got FOUR GB OF RAM!!! finally
i will send a picture of the case with the rams slots and the rams and a photo of the graphics card blocking the ram slot!!
Thanks for your help!!!

how the hell is the gpu blocking the ram slots? mini atx board or what?

ChrisGreece52 · « **Reply #48 on:** April 21, 2013, 09:13:30 pm »

no just the edge of the gpu board kinda stops the memory slot youll see in the pictures.

I am sorry for the poor quality. The photos were taken with a mobile phone (Xperia X8 3.2 MP) and using an LED flashlight as a light source (because i forgot to take the pics when the pc was on the desk with my powerful desk lamp)
