RAM Kingston 667

Hello
Well, the difference is only noticeable if you put 2 modules of 2Gb each in dual-channel, then you would have 4Gb and dual-channel would favor you in accessing memory, you would gain in performance as well as in capacity.

check to see what your motherboard is like, because you can't put all the ram modules you want. depending on the motherboard you have, you can put 2 or 4 ram modules, and depending on the amount of memory on each module, you can have more or less ram in total.
you should also take into account that mixing different ram models usually causes problems, and that although everything may work at first, it is possible that it causes instability problems and your computer gets stuck, has blue screens...
my advice is to check to see if your motherboard has 2 or 4 connectors for ram memory, and depending on what you have, buy new ram memory, but don't mix old with new.

check your motherboard to see how many RAM modules it can support, because you can't just add any RAM modules you want. Depending on your motherboard, you may be able to add 2 or 4 RAM modules, and depending on the amount of memory on each module, you may have more or less RAM in total.
you should also keep in mind that mixing different RAM models usually causes problems, and although everything may work fine at first, it may cause instability issues and your computer may freeze, get blue screens…

+1 Totally agree, moreover, to take advantage of dual-channel (if supported) the modules must be exactly the same, otherwise not only can there be problems, but the memory can be damaged.

My motherboard model is as follows:
Asus P5KPL (3 PCI, 1 PCI-E x1, 1 PCI-E x16, 4 DDR2 DIMM, Audio, Gigabit LAN)
As I understand it, it does support 4 RAM modules.
Regarding the new RAM, I had thought about buying new ones, but identical, I'm not sure if I explained myself well.
Having the same type of RAM, just a 2gb module or two 1gb modules new.
How could I perform dual-channel in the case that I put two new modules of 2gb each?
The thing is that I thought I would spend around 35€, but of course, if I have to buy the two modules of 2gb each...
Thanks again,
A greeting

I understand that you wanted to get rid of the two 1Gb modules you have and use only one new 2Gb or two new 1Gb. To stay with the same amount of memory it is absurd to buy new modules

I don't know if I misunderstood, but the recommended thing is to expand.It so happens that DDR2 memory is scarce and expensive, and being obsolete it is not worth investing much in it.
Anyway, there is also the second-hand market, where you can find some offer.Regarding dual-channel, in theory you shouldn't have to do anything, the BIOS should detect when you connect two identical modules in the appropriate slots and directly activate dual-channel (if your motherboard supports it).
In case it is not automatic and does not indicate it to you in the POST (when starting the PC) then you would have to activate it yourself in the BIOS, that's all.Regards

It's the Asus P5KPL plain and simple or does it have a last name... because there are several versions of the same, some more cut down and others more vitaminized.
Dual-channel is mounted in the slots of the same color (socket 1 and 3 - 2 and 4)
Best regards. -

No compañero, what I want is to expand the memory. Sorry if I explained myself wrong.
What I wanted in the beginning was to expand the RAM from 2gb to 4gb.
The doubt was how to do it, that is, if buying two 1gb modules or a 2gb module.

Now,
regarding your comments about dual channel, can it only be done if I have two 2gb modules?
Regarding what Nemo said, I have my RAM set up as he says, one module in each of the same color, but of course, these are 1gb each.

Just in case it helps you, in the "Aida" I was able to see the type of RAM Bus:
"Dual DDR2 SDRAM Bus Type"
With this I imagine that my motherboard will only accept this type of memory, so we are already closer to deciding which one to choose...

Ah vale, perdón, no te comprendí a la primera.
Well right now you would have dual-channel activated if you have the modules as you say.
Indeed expanding to 4Gb is the best option.
Starting from the base that mixing old and new memories is not recommended, you would have to replace those two 1Gb modules.
To expand to 4 Gb the best in your case is 2 equal modules of 2 Gb, they will be cheaper than 4 of 1Gb.
The problem is what I mentioned before, that the memory that your motherboard supports, the DDR2, is scarce, expensive and already obsolete. The best thing would be that you look for some second-hand kit of 2x2Gb (4gb), that the price will be very reduced and they will work perfectly for you, or if not already go to a new kit, but the prices are like this more or less:G.Skill Performance DDR2 800 PC2-6400 4GB 2x2GB CL4 F2-6400CL4D-4GBPK RAM Memory

Hello!
From what I understand, you have 4 RAM slots on your motherboard, and you have 2 occupied, with 1Gb DDR2 667 modules, with dual channel activated (the 2 memory modules mounted alternately between them, that is, in the slots of the same color). I would recommend, for price and simplicity, that you keep the memory you have now, and buy another two 1Gb DDR2 667 modules, to place them in the two free slots you have.
The 1Gb modules of 667 are the cheapest you can buy in DDR2, and having already two of those, buy another two (I just bought 2x1Gb DDR2 667 for my sister's computer for 32€ on amazon.es) and you would have a total of 4Gb of RAM memory and you don't have to discard the memory you already have installed.
Goodbye! Agur -
Overclocking for more than six months… :eoh:
It was already said at the time that mixing memories from different models, even if they are of the same frequency, is not recommended, it can cause instability even if it seems to work perfectly at first, hence the recommendation to upgrade to a complete kit of 2x2Gb or 4x1Gb.

Stroke of the oar! My mistake, that happens when you don't look...
