okay i just got my new set of OCZ ram 6gig 1600mhz 6-8-6-24 it started it up fine automatically at 1066 so i restarted went into bios set it to x.m.p for some reason it didnt auto change everything like it normally does so i just set my speed to 1600mhz and it asked if i wanted to keep the current voltage or let it auto change it if my ram needed it i let it do auto booted up realized i didnt set the timing restarted set the timings at 6-8-6-24 noticed ram bus voltage was at 1.799 when its supposed to be at 1.65 and wanted to know if this is bad and if im killing my new ram by taking all the time to type this while its frying itself at a higher voltage

If the DRAM Voltage went up then I too assume that you are OC the CPU.

I would suggest that you Manually set: Speed, CAS and DRAM Voltage all per spec.

What MOBO & What EXACT {link} RAM?

asus rampage 3 extreme and i7 980x @ 3.4 i believe

and bios wont let me manually change voltage on ram

This is STATISTICALLY IMPOSSIBLE you are the THIRD i7 980X + R3E in 3 days with this PROBLEM.

THEREFORE: 1. BAD CPU or 2 BAD RAM.

I will be editing and cross linking the posts.

Statistical Anomaly (3 R3E + i7 980X)

There's coincidence and there's production issues. Clearly, the observation is the MOBO + CPU, but since I'm not seeing a whole lot of i7 980X causing problems -> my assumption on the root cause is 80% MOBO and 20% CPU. I thought you all would be interested in seeing the links. Keep in mind I 'NEVER' have this much trouble helping people OC RAM - it's simple. But I find myself suggesting 'FRINGE' BIOS settings that are typically meant for a rare instances with 6 sticks of RAM with 'average' underpowered MOBOs.

I cannot rule-out either CPU or MOBO.

@jaquith: I would tend to lean toward a possible recent production issue with the RE3 over a CPU. With all three links you provided, the common elements are MOBO & CPU but i7 980X isn't seeing issues outside of the RE3 (or just not being reported here :)  ). In my world of Quality Assurance, this would begin to point to the root cause. Of course, you would go deeper into the issue to find all possible issues with the board to determine the defaulty component(s).

Question - Where did you purchase the CPU and MOBO?

i got them both from newegg, i mean the ram the works its at 1600mhz 6-8-6-24 and is running in triple channel like its supposed to i just dont know much abotu ram or voltages and wanted to know if letting the bios auto set the rams voltage to 1.799 is bad for it i tried pressing my fingers across the ram sticks while playing a game and i feel absolutly nothing on them

1.799V for your RAM is NOT SAFE!! The Intel i7 has a 1.65V limit for memory voltage. Running at 1.799V will damage the on-board memory controller on the chip! Please decrease the voltage to 1.65V or less quickly!!

Another often disadvantage, assuming XMP settings, it whenever you OC the CPU it takes the DRAM along for the ride. Try the following.

AI Tweaker:
AI Overclocker Tuner {Auto} -> {Manual}
CPU Level Up {Auto} or select your CPU from list if available
DRAM Frequency {Auto} -> {DDR3-1600MHz}**
DRAM Timing Control hit enter -> enter ALL of your timings 9-9-9-24
...

DRAM Bus Volatge {Auto} -> [enter the correct spec'd voltage]

Save & Exit

okay since bios loves to hate me it still doesnt let me manually set the DRAM bus voltage so i hit f5 do put everything at defualts rebooted DRAM voltage was at 1.508 i did NOT use xmp i manually set the speed and timings 1600mhz 6-8-6-24 told it to keep the current voltage heres a pics of spd tab all happys is had?

Well, look at the images you are running the 1600 at stock @ 1066 {the CAS changes}; so NO those sticks are NOT set correctly.

OCZ3P1600C6LV2G = OCZ3P1600C6LV6GK

AI Tweaker:
AI Overclocker Tuner {Auto} -> {Manual}
DRAM Frequency {Auto} -> {DDR3-1600MHz}

CAS# Latency -> 6
RAS# to CAS# Delay -> 8
RAS# PRE Time -> 6
RAS# ACT Time -> 24

Timing Mode -> 2T

QPI/DRAM Core Voltage -> 1.35v~1.40v
DRAM Bus Voltage -> 1.65+V

{I don't care about BA; I'm as high as I can go}

Good Luck!

my ram isnt running at 1600mhz 6-8-6-24? is cpu-z lying to me? im confuse :(

The JEDEC #4 is the Speed and CAS that you want to look at and I assume you know to take the Frequency X 2 {e.g. 800 MHz x 2 = 1600 MHz}.

well thats certainly weird, how do i fix problem? i went into bios just know and everything there set correctly so why is the memory tab of cpu-z lying to me?

DDR = Double Data Rate; therefore 800 MHz per JEDEC #4 is 1600 MHz. If the JEDEC #4 showed 1600 MHz then you'd have 3200 MHz RAM. It's the Multiplier; the same analogy is with a CPU Multiplier. Example i7 930 2800 MHz / BCLK 133.33 = 21 (CPU Multiplier) -> is the 'speed' of the CPU really 133.33 MHz?

It's NORMAL and CORRECT there's nothing to fix.

If I look at the (2) images you posted, then the ANS is you have 1600 MHz RAM running per JEDEC #4 609 X 2 = 1218 MHz ; if it shows JEDEC #4 800 X 2 = 1600 MHz then 'yes' you're running at 1600 MHz. Keep in mind the BCLK varies and if you're getting 780~820 then it's also normal to have some fluctuation.

Some JEDEC #4 will have another column with XMP e.g. 'XMP 1600'.
