Hi all !!

My system has atm G.Skill Extreme PC3-12800 DDR3 1600 4GB 2x2GB (Dual Channel).

Now I want to upgrade it and go for 8 Gb BUT the place I am going to buy this (and other things) has out of the stock this kind of ram.... The alternative is Kingston HyperX 4GB DDR3 1600 PC3-12800 2x2GB.

My System:

- QUAD Core (775) + ASUS Maximus Extreme

G.Skill Extreme PC3-12800 DDR3 1600 4GB 2x2GB:

- 9-9-9-24 (1.6v)

Kingston HyperX 4GB DDR3 1600 PC3-12800 2x2GB:

- 9-9-9-27 (1.7-1.9V)

So Now the question is: Am I going to have any problem having G.Skill Extreme PC3-12800 DDR3 1600 4GB 2x2GB + Kingston HyperX 4GB DDR3 1600 PC3-12800 2x2GB ??? Will affect my current FSB??? What happend with that 1.6V vs 1.7-1.9V ??? I would like to have the same fast system but with just 4gb more....

I will by rhis in www so I must be sure that It will work correctly.

TY and sorry for my english...

Welcome Newcomer. First of all, do you really need to increase your RAM? 4GB is actually plenty, unless you're doing video editing, or similar demanding tasks.

If you do increase your RAM, using the HyperX shouldn't give you any problems. As for the voltage, increasing the voltage to 1.7 won't hurt, in fact even if you were able to get another 4GB kit of your current RAM, you'd need to increase the voltage slightly anyway just because you'd be occupying four DIMMs.

Hi !!

First of all ty for the fast answer !!

The reason to update ro 8Gb is that now I am using a high end system atm and I will probably continue with it some time but is a 775 one... (Quad core + maximus extreme + RAID hdd + GTX480 + X-fi ........) in full load I use like 85-90% of RAM... I would hate to be in trouble becouse of the ram... And I am afraid that after just a few time I will have RAM problems.... And then all DDR3 (1600) willl not be as easy/cheap evailable as it is today... The price now is not that high... and since I am going to buy more things I will not need to pay twice for send cost...

Again ty for the help... and again sorry for my english.

OK. If you need the increased RAM, then go for it. Keep in mind if using an i-series CPU, Intel recommends not to volt your RAM higher than 1.65. So, while increasing your current RAM to 1.7 won't kill it, but be careful of the voltage setting if you're planning on using an i5 chip.

Hi !!

With my current system (775) is not posible to install that kind of CPU (i3/5/7)... MY CPU is Intel Core 2 Quad Q9450 2.6Ghz FSB 1333 12MB Box.

So My mother board will set the 4 slots to 1.7 ?? automatically ??

I mean Gskill are 1.6 kingston are 1.7 - 1.9.. Am I going to need to adjust something ?? Will I need to change FSB or something too ?? Am I right thinking that everything is going to work perfect as now ?? Well the timings 9-9-9-27 vs 9-9-9-24 will turn all into 9-9-9-27 which is not too different right ??

I have just confirm the buy so just need to wait....

TY again !

I apologize, your post:

"The reason to update ro 8Gb is that now I am using a high end system atm and I will probably continue with it some time but is a 775 one... " and "and since I am going to buy more things I will not need to pay twice for send cost..."

made me think you were planning on mobo upgrade, too.

If you weren't aware, the default voltage setting on is [Auto]. what this means is that the BIOS will determine at what voltage to operate your RAM. This also means that the BIOS can increase and decrease the voltage as it sees fit. If you want to run your RAM at 1.7v, you'll have to manually set this in the BIOS.

You don't need to touch your FSB, as this is a separate section of the BIOS. As for the timing, you can set this manually, too; in fact, you should. If your timings are already set at 9-9-9-24, leave it alone. If you run into stability problems, go back into the BIOS and loosen the timings a little bit.

Really ty for the help again !! that "and" more things was about some cords, conectors, and many other things :) .

I spoke about fsb becouse my cpu is 1333 my current fsb goes to 1660 which increase my CPU speed to 2906 also ram speed but if with the new ram I cannot reach the same fsb config then It could be posible to need a little lower fsb...

As I can see now I am runing my gskill ram at 1.8v so.... theres no reason to think voltage is going to be a problem....

Again really ty for the help !
