I'm not overclocking I just want my DDR3 to reach 1600 as expected

[Di7]

Hello..

I bought two triple channel kit desktop memories..
They are: OCZ Gold 12GB (6 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800).
Model: OCZ3G1600LV6GK
http://www.newegg.com/Product/Product.aspx?Item=N82E16820227365

But when i installed them thee Gigabyte EX58-Extreme motherboard shows me that I have 1066 Memory at the boot.

What is the matter?
How can I get the work normally as expected?

you will probably need to change the ram ratio to bump the ram up to 1600
either that or raise the fsb, if you are going to go the fsb route take it slow, im not sure if you will be able to hit 1600 with 12gb of ram, which may be the reason it has defaulted to a slower speed.

1066 is the default for i7, you will need to manually change it.

Hey all..

thanks for the responses..

PsychoSaysDie.. Yes.. When I set the memory multiplier in the bios to 12 .. I see that it can reach 1600 (frq)

But I did not apply it because:

1- I want to be sure that it has no side effects..
2- I'm not sure if changing the memory multiplier is all I have to do.. Shouldn't I change the Cas Latency
the Timing and the Voltage? .. what is the best set for each one?


Is all I need to do is fixing the memory multiplier..?

Manually change the mult to run at 1600. You'll also want to manually change the voltage and timings to whatever the RAM is rated for. It'll probably be something like 9-9-9-28 or 8-8-8-24 at around 1.6V.

I changed it and now it shows me 1600Mhz at boot screen but 5 LED board's lights are ON all the time ( 2 of CPU LEDs and 3 of Memory LEDs).. Should I turn the memory back to normal?

I'm afraid these people are not giving you the best advice.

Speed DDR3 1600 (PC3 12800)
Cas Latency 8
Timing 8-8-8-24
Voltage 1.65V

These are the settings that your RAM is rated for. I pulled it off the Newegg link you supplied so this should be right for your ram. As long as you follow this you shouldn't have any problems.

If you are worried about it then go download SiSandra and pressure test your system to make sure it's not giving you errors.

I ask the support about the issue and it seems impossible to get 1600Mhz normally..

That is because all RAMs on the market at 1600 needs 1.65V for i7 amd my motherboard Gigabyte EX-58-Extreme does not give 1.65v option..

When I tried both the DRAM voltage to 1.64 and 1.66v and set SPD to 12.0

I got 1600Mhz as usual, not the first time doing that, but 2 LEDs of CPU voltage (green and orange) on the motherboard are ON and also one green LED voltage of the memory.

In the motherboard's BIOS there was a message. Warning: CPU and memory may be damaged or reduce life cycle when over-voltage.

In Gigabyte Ex58-Extreme guide they wrote:

This motherboard contains 4 sets of overvoltage LEDs which indicate the overvoltage level of the CPU,
memory, North Bridge, and South Bridge.
CPU (CPU Voltage)
Off: Normal condition
L1: Level 1 (Slight, green)
L2: Level 2 (Moderate, yellow)
L3: Level 3 (High, red)
Memory (DDR Voltage)
Off: Normal condition
L1: Level 1 (Slight, green)
L2: Level 2 (Moderate, yellow)
L3: Level 3 (High, red)

So I can not have 1600Mhz without hurting my CPU/Memory..

Yes you can. Also, the 1.65V doesn't need to be exact. I'm running my DDR3-1600 at 1.64 right now, and it works fine (it's rated at 1.65). Try running memory at 1.64 at rated speed, and then boot into windows. Check CPU-z and see what it says your core voltage is, because there should not be a significant increase in CPU core for a change in memory speed.
