My new RAM

by DatThor / September 17, 2013 3:20 AM PDT

Hello there,

I got some new RAM.
Corsair XMS 2 Xtreame performance DDR2 memory on the front side.
Corsair CM2X1024-6400 5-5-5-12 1.9 V ver5.2 800 Mhz 1024 MB 748047 08081435 XMS2-6400 on the backside.
I also have these one
2xKingston 1GB 240-Pin DDR2
DDR2 667 (PC2 5300)
Cas Latency 5
Voltage 1.8V
My mother board is an ABIT KN9 Ultra.
Website is telling this:
Four 240-pin DIMM sockets
Supports Dual channel DDR2 800 ECC/non-ECC,
Un-buffered memory
Supports maximum memory capacity up to 8GB

So to make it clear after this technical information,
I have 2x those kingstons and they work fine.
But i wont to add those corsair. However when i do it, i get a lot of blue screens.
I tried to replaced them, like 1-3 for kingston and 2-4 for crosair, and a lot of other combo's. But it seems not to work, or i get like 2.5,3,3.5 and sometimes 4 GB.
But they give bluescreens,
memory management and some others....
I hope you got some ideas what i should do, do they even work together? Pls help me Happy
Enough information? Otherwise tell me
Thank you, Thorwin

When we add more ram there are a lot of parameters to check.

http://www.corsair.com/en/memory-by-product-family/xms-classic/cm2x1024-6400.html calls out 1.9V and your old RAM is 1.8V which is usually close enough but as in all prior discussions you either replace them all of the same make/model or use CRUCIAL.COM and you still get to keep them all the same make and model.

Mixing memory sizes, makes is more fun than herding cats.

Well ty for your quick reaction.
I have this old 512MB ram laying here.
It's a Samsung KR 0427, 512 MB 1Rx8
PC2-3200U-333-10-A1
M378T6553BGO-CCC
Now i have this,
Slot 1: The Kingston
Slot 2: The Corair
Slot 3: The Kingston again
Slot 4: The Samsung one.
Now i have 3.5 GB ram and it's working fine,
I wonder why this works, but 2 corairs not.
And it put it on 1.9 V in my bios. No bluescreens since i did that combo.

slowest DIMM in the system (the Samsung) vice the fastest.

If you read your MB manual or look nearly anywhere on the WEB, system manufacturers and MB manufacturers recommend that all you RAM be the same speed, same capacity from the same RAM mfg. You don't want to mix RAM speeds, RAM capacities or RAM mfgs....this helps ensure the system works reliably at maximum design speed.

What operating system are you using and what version is it...32bit or 64bit ? What do you use the PC for ?

3 different RAM cards
by DatThor / September 17, 2013 9:05 PM PDT

Ty for your responds,
Well i"m using my PC to game, i have a laptop apart for work.
This PC got Windows 7 Ultimate 64 bit.
And i'm using the corair with the settings of the first Post.
You say that ram should have the same speed.
But now i'm using 3 different RAM cards and they work fine.
Then i'm still not really getting why 2 corsairs and 2 kingstons aren't working.
I will try to switch the corsair and see if the other one is broken.
Have a nice day

In reply to: 3 different RAM cards

Well I think i gone sell the corsairs, how much would it get me?
I'm thinking about 20 euros. BTW: The Samsungs, how much are those worth?
With that money i would try go get other 2x1 GB that would work.
Any not to expensive but that would work. But know i wonne be sure it works.
So any ideas what RAM i should take?
Ty
PS:If you know a way to get the corsair to work, pls tell me.

In reply to: 3 different RAM cards

slowest RAM in the system. With all of your RAM running at the speed of the slowest degrades performance of the entire system.

Bottom line, you should have 4GBs if not 8GBs of RAM and a good video card (GPU) for decent gaming performance. Otherwise slow is how you'll go.

Speed
by DatThor / September 19, 2013 2:43 AM PDT

2x Kingstons are 677 MHz
2x Coirsair are 800 MHz
2x Samsung are 533 MHZ
So i wonder what i should do then.
I'm able to sell some if i need to. But which should i buy then?
I don't wont to go over 20-30 euros. And in total i would like to have 4 GB.

In reply to: Speed

decision...but the decision is up to you.

Optimal RAM config is a sufficient quantity of RAM from the same mfg, the same speed, same same same ....otherwise you risk decreased reliability, decreased speed. You want to maximize performance and reliability .... mixing brands, speeds and capacities of RAM can adversely affect both reliability and performance.....who wants that ??

"Memory is designed to be backward-compatible, so generally speaking, you can safely add faster memory to a computer that was designed to run slower memory. However, your system will operate at the speed of the slowest memory module."

Set the RAM speed manually (not SPD) to 667 and leave at 1.9V with 2 Kingston and 2Corsairs in the slots.

There can be other factors here.

But all these posts and I can't tell what we are working on.

It could be the old mix different memory sticks issue or it could be the old heat sink compound or out of date motherboard bios but as it stands, without details I won't guess.

I'm trying to find a way to get the crosairs and the kingstons work so i have 4GB of Ram.
If that doesn't work i'l buy some other ram.
But what information do you need then?

My current bios is Phoenix Technologies, LTD 6.00 PG, 19/11/2006(as msinfo32 say)
I'm not sure if that is the lastest version of my motherboard. When i was looking that up i got a lot of sites that doesn't seems to be trusted at all.

you seem to want to make a silk pursr out of a sows ear. Purchase the proper matching RAM and be done with it. In the mean time run with just the original.

download the above and test each memory stick, one at a time. If you get bad readings on one, take a picture with a camera if it's still under warranty, get RMA and send that one back for a replacement.

Awkard, i did some more reseach about updating and i found this:
Regedit -> HKEY_LOCAL_MACHINE->HARDWARE->DESCRIPTION->System
Then it's saying this: SystemBiosDate: 11/19/07
What should be the last bios update. I will check memtest86.
I thinking about buying 2 more crosairs of the same type.
Those 4 should work right?

Why not look at the BIOS boot screen?

In reply to: Bios

Windows is not known to get this right. You can try BELARC ADVISOR's report too but if a pair or sticks work then 2 pairs of same should be fine HOWEVER there have been exceptions in the past when the motherboard chipset ran out of chip select lines and well, that's a very deep discussion. It's also why many folk just head to crucial.

Well i'm sick of it, they just don't work out together.
So I gone buy 2 more crosairs(the same) and they should work.
But I wont to thank you all for this help, it's not always easy but you did what you could do.
Have a nice day!
