GA-X79S-UP5-WIFI RAM issues

[pSyKo]

The motherboard has 8 slots but I can only use 4.
If I install 8, BIOS detects them as 1333mhz with 9 9 9 24 timing. If I attempt to change these settings it fails to boot. If I leave them it freezes my system whenever I try and play a game. If I install 4, I CAN change the settings and timing to 2133mhz and its proper 9 11 10 30 timing and everything is fine.
I referred to the RAM compatibility list for the motherboard and that's where I discovered it can only accept RAM in slots 1 2 3 & 4 for this memory
(CMD16GX3M4A2133C9)

What settings are you changing? I'm running 32gbs in my x79-UP4 at 2133 and not having any problems.

But the only thing I change is the speed fromm 1333 to 2133. I don't change anything else.

But I'm running G-skill for the memory. Plus I don't care what the other settings are set at. As long as it is running at 2133.

I just went and check what the memory is set at. I run no profile the memory is running at 2133 and the other settings are at 11 - 11 - 11 - 28.

The G-Skill is 2133 at 11 - 11 - 11 - 30. Like I said the only thing I set is the speed from 1333 to 2133 and that is it.

[pSyKo]

I only attempted to change speed from 1333 to 2133 and rams timing.
Like I said, if I leave 8 in, games don't work and if I change speed and timing it fails to boot.
If I install 4, it still auto detects it as 1333 and 9 9 9 30, not 2133 and 9 11 10 30 AND still crashes playing games but it will let me change timing and speed and then it works fine.

Two things you can try and that is update the bios or try to bump up the volts on the ram.

It will set it to 1.5v most of the times. Your memory it is set to run at 1.65v. Just set it at 1.60v and see what happens

[pSyKo]

Ram IS 1.5v and I have F4w which is very latest

Ram specs

I was going by what you had up there and not a #. Have you tried to adding one stick at time to see if you have a bad slot.

With the other 4 sticks of memory. Or have you tried to swap memory around to see if you have a bad stick out memory.

I had a Gigbyte board one time that had six slots on and I could only use 5 slots.

The last slot give me bad readings on the memory speed. Gigabyte did fix it for me too.

[pSyKo]

On memory compatibility chart, I can only use this ram in slots 1, 2, 3 & 4.
That's what I want rectified

You might have to email or call Gigabyte because I just played around with mine. But you can check this thread out at tweaktown.

In the BIOS under the RAM settings, set the "Performance Enhance" setting to Normal. I think default is Turbo. I was getting BSODs with it set at Turbo and had to set it to Normal to get everything stable.

[Scracy]

As stated set performance enhance to normal. Also set xmp to profile 1 and ram multiplier to 21.33 i had similar issues with my corsair ram @2133. Even though my dominator ram is rated at 1.5v i had to increase vram to 1.6v to get it to be stable and reliable maybe increase your ram voltage to 1.6v should help.

I finally got answer from Gigabyte.

"Thank you for your kindly mail and inquiry. Since memory speed is supported depends on the CPU being used. Please refer to your CPU's spec HERE. With this CPU, it supports memory type DDR3-1066/1333/1600 therefore user cannot see higher speed option in BIOS. The problem you mentioned, It might be the system/hardwares cannot accept your overclock settings, and we will not guarantee any result caused by system overclocking.

Regards,
GIGABYTE"

I believe they are trying to say that they have no idea.

[dmdilks]

That if funny that I'm running the same CPU you are and I know it isn't the same board. But mine is running at 2133.

Plus the two of you are running Corsair memory and I'm running G-Skill. So if the CPU can only support up to 1600.

Then why do Gigabytes make boards that say it will support memory 2133 without any overclock. Then tell somebody that.
