DDR2 RAM combination problem

[Zvonkoo]

i have asked this on forum http://www.tomshardware.co.uk/answers/id-1968554/ram-combination.html
and i have bought 2gigs of RAM 2x1gb at 667MHz http://images.esellerpro.com/2131/I/754/83/DCP_9574.JPG , and i have put it in green slots they were empty and when i turn on my pc its just black screen , what is problem?
I have 2x Kingston 99U5316-001.A02LF 1GB @667MHz and i have bought 2x samsung 1gb 2rx8 5300U @667MHz

It may be incompatibility between the two different ram brands. Have you tried running just the new ram?

i will try

pc works with 2x1gb Kingston , and pc works with 2x1gb Samsung , pc does not work with 2x1gb Kingston and 2x1gb Samsung it says on my windows 8 pro (its activated windows) , we will restart your pc just to collect some information , something like that and then restarts and its black screen

Have you tried resetting CMOS with all the sticks in? It is incompatibility and could be that you will have to play with timings if it does not reset with CMOS reset.

How do i do that im just 15 , i have no experience with everything

Resetting CMOS is usually done by shorting a jumper on your motherboard for a few seconds. To find out whre it is you will want to review your motherboard manual which you can often find online from the manufacturer, but it is often near the small round battery. You can also remove the battery for about 20 seconds to achieve the same result. Make sure the computer is off and unplugged. The motherboard model is usually printed on the motherboard and you can also identify it using the program CPU-Z under "mainboard." Some memory controllers have difficulty running 4 stick of memory and need voltage increased. In BIOS if you have that option you can try to increase the North Bridge voltage to up to 1.4 volt. Bumping the memory voltage up .1 volt may also help, but try Northbridge first.

could i make some damage to my pc by doing that? is it dangerous

 

[rolli59]

Not by resetting CMOS, slight increase on ram volts 0.1-0.2 volts is fine as well.

i increase that in BIOS?

 

[rehed21]

You can't damage the PC by resetting CMOS as long as the PC is powered off and unplugged - it is commonly done to reset the BIOS to default values, but usually only when the computer won't boot to BIOS. You should go into BIOS and select "select optimized defaults" instead of resetting CMOS to see if that solves your memory issue. If that doesn't work, in BIOS set your memory to AUTO. If that doesn't work increase your Northbridge voltage by .1 volt at a time to up to 1.4 volts (it's probably at 1.2 volts currently). It is not dangerous and is also commonly done. I expect that will work if nothing else has since it will give your memory controller more power to manage the 4 sticks of mismatched memory. If that doesn't work go into BIOS and "relax" the timings. For example if your timings are normally 5-5-5-18 try 6-6-6-18. If that works then you can go back later and "tighten" the timings to as close to the original until it doesn't boot again then go back to the previous setting when it did boot.

Is it an AMD or Intel system? Never mind looked in the link to the other thread.

its intel core 2 duo 2.2GHz , 2x1gb of ram 667mhz and i have 2x1gb of ram to install at 667mhz i have one graphic card radeon x1550 and sound and tv card

 

[rolli59]

Your best bet is to follow reheds's instructions to try to get it to work. If the reset CMOS does not fix it I would start with the 0.1 increase on NB then try the 0.1 on the ram and so on.

do i do that with ram that i have (2gb) or with all ram (ram which i want to install)
p.s running bios

 

[rehed21]

You want to do it with all of the ram installed.

 

[rolli59]

All ram installed!

 

[rehed21]

Which step solved the problem?

 

[Zvonkoo]

All ram installed!

minimum is 1.80 at 2.20 says tgat its not recommanded settings system may be unstable , and max is 3.30
this is DRAM voltage , do i change dram or NB voltage ?

 

[rolli59]

I would start with ram voltage and do + 0.1 volt first.

 

[rehed21]

NB voltage to no more than 1.4 volt. If that doesn't work increase DRAM to 1.9 volt.

 

[Zvonkoo]

NB voltage to no more than 1.4 volt. If that doesn't work increase DRAM to 1.9 volt.

NB Voltage (V)
Min:1.250V
Max:1.650V
Color Message :
Gray : Default Voltage or Safe settings
White : High performance settings .
Red: Not recommanded settings . System may be unstable .
--------------------------------------------------------------------------------------
DRAM 1.80V Min , 3.30V Max
1.80V - 1.95V Gray
2.00V - 2.20V White
2.30- 3.30 Red
--------------------------------------
NB Voltage 1.250V Min , 1.650V Max
1.250V - 1.325V Gray
1.350V - 1.425V White
1.450V - 1.600V Red
--------------------------------------------
Rehed said NB voltage more than 1.4 and that is white is it safe?
Rehed said DRAM to 1.9 and that is gray its okay
------------------------------------------------------------------------------------------------
So i first try with NB at 1.4V and DRAM at auto ?
If that doesn't work i'll try with DRAM 1.9 and NB Auto or 1.4?

 

[rolli59]

I would start with both on the Gray so NB 1.325, try if not enough ram to 1.9 try and so on white settings is OK but I would not take the ram past 2.0.

i tried with nb 1.325 and dram 1.9 , it turns on and windows circle appears and then circle finishes and says Collecting information for you something like that and it resets and again and again , what NB and DRAM now?

 

[rolli59]

Check your timings, make sure it is using the lower timings if there is difference and as well make sure that command rate is 2T not 1T.
Then try 1.4 on the NB if that does not work then 2.0 on the ram.
