Hi,
What speeds and timings are people getting with 12gb(3x4) or 24gb(6x4) memory kits on either of these boards?
Asus P6X58D-e
Gigabyte GA-X58A-ud3r
I've written many an e-mail to memory and mobo companies and not getting any definitive answers. I'll be using an i7-950.

Thanks!

Look at newegg memory section to see speeds and timings of memory they sell. The lower the latency the better.

I went with the Asus p6x58d-e. Any brand of memory recommendations that are working at 1600mhz on this board? I'm looking at the G.Skill Ripjaws, maybe 2 sets (12gb 3x4). They are cas6 1600mhz and 1.5v. $159 on sale.

They also have these with cas8, 1600mhz but 1.6v instead of 1.5. $249 Maybe I can get the cheaper ones down to cas8 because the voltage is for 1.5.

Still debating 12gb or 24gb of ram for a film scoring audio workstation loading large amounts into ram.

The boards u chose have DDR3 1600 MHz memory standard. If u won't go OC, all u have to do is just looking for the the 1600 memory u want. It (MHz) is the mem speed.

The mem timing is different and it doesn't effect the speed (MHz)
Here two memory stick for example:
CORSAIR XMS3 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

G.SKILL 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Each of them is rated to run at 1600MHz. The Corsair has CL 8-8-8-24 timings, and The G.Skill has CL 9-9-9-24 timing. Which is faster? Like it's written above, both are running at the same speed (1600MHz). The diffrence is corsair then waits for 8 clock cycles before it moves onto the next step, while G.Skill have to wait for 9 clock cycles. So, in this case, we can say the corsair is more 'efficient' than The G.Skill

Don't forget to check your motherboard's memory compatibility before purchasing some memory sticks.

Thanks for the info. I am really just trying to find out people's experience with 12gb(3x4) or 24gb(6x4) on a Asus P6x58d-e. I've read that when filling all six slots on x58 boards you have to slow your ram down as opposed to just using three slots. Debating 12gb(3x4) of faster speed and timings as opposed to 24gb of slower speed and timings. I'm wondering if I will notice the a real world difference if I have to slow down the 24gb to 1066 or 1333.
I will be loading things like LA Scoring Strings - http://www.audiobro.com/html/lass.html
and virtual pianos and drums that take up loads of ram.
I've ordered two kits of the G.Skill Ripjaws 12gb(3x4). I will try one kit and see how it goes and wait to open the other.

I don't have 12 or 24GB, but I have all 6 slots filled and didn't have to slow down my memory. It may be an issue only with the bigger kits, but I'm not sure. Never heard of the problem.

I've heard some issues bout P6X58D-E. While using 3x 2Gb of PC3 12800, the mobo detect it as 6 Gb at 1066 MHz, and detect only 4Gb when it's manually changed to 1600 MHz. Need some BIOS update perhaps..
