Hello!

Im used the config:
GA H55N USB3 mini-itx motherboard (BIOS F5b)
Intel Core i3 530 (2,93GHz) CPU
KINGSTON HyperX 4096Mb DDR3 1600Mhz CL9 XMP KIT
KHX1600C9D3LK2/4GX
WD500GB Sata2 HDD
etc.
Win7 64 bit

Please send me a correct BIOS setup (H55N) the KINGSTON HyperX 4096Mb DDR3 1600Mhz CL9 XMP KIT (KHX1600C9D3LK2/4GX) low voltage memory kits.

I probably the motherboard bios setting but restart and dont working h55n with kingstone memory...

Kingstone memory is 1,25-1,35V setting but H55N motherboard default DDR Voltage is 1,5V ?! (bios setup dram voltage 1,4V but system restarting dont run...)

What would be the accurate settings to these Ram settings the BIOS?

Exactly where and what I shall set?

Thank you for the help!

Thx.

You can try "Normal" Dram voltage setting, or you will have to test 1.3V as that is the lowest you can manually set. "Normal" may correctly set the specified amount in the XMP profile, so test that first.

The Dram voltage setting is in the MIT Section, Voltage settings page.

Did you set Auto, then reboot and look in PC Health section to see what voltage is actually applied? If you did not please do that for Auto, and Normal, maybe one of those will be closer to 1.25-1.35, if not you can just use 1.3 or 1.4, both should be a little less anyway (Like 1.28-1.38)

I rehearsed the profile 1 and the profile 2-five but one do not use a profile the motherboard...

I can run it with manual settings on 1600 only the Rams, it XMP setting: Disabled!

Maybe, how the motherboard does not favour this type?

Does not cause damage the RAM 1,5 Volt?

Profile at 1 QPI Voltage 1,3V higher... not tall this?!

Base QPI Voltage the motherboard is 1,05 V...


Thank you for the help!

Thx.

I always suggest against XMP anyway, so I would suggest you set things yourself manually.

No, 1.5 shouldn't damage the memory, but you shouldn't run it there if you don't have to.

You can manually set 1.3V, which should be 1.28 or so.

[AlexRogan]

OKAY.

Thank you, I make an attempt then!

[Lsdmeasap]

Let us know how you get along trying that, and please let me know what voltages are actually applied when you set Auto, Normal, and 1.3V.

If needed I can ask if Gigabyte can add in 1.25 as well for lower voltage modules, if "Normal" or Auto does not give that value, and 1.3 is not close to 1.25

[AlexRogan]

Neither the XM. profil1 and neither the profil2 is out of order... (XMP settings correct?!)

From the sole working setting the pictures here can be found, but shows here, that 1,5 Volt give... (manual settings, XMP disabled)

Dont run away neither 1,3 on 1,4 Volt, I do not experiment time.... BIOS is needed refreshing....

When expected the new bios what supports the modules with low voltage memory modules current?

[Lsdmeasap]

Disable XMP

Set BIOS 1.3V, what voltage to you get on reboot?

Set BIOS normal, what voltage to you get on reboot?

Set BIOS auto, what voltage do you get on reboot?

I see you are using Fail Safe settings, please start all this testing (And future use) with Optimized Defaults.

[AlexRogan]

Disabled XMP

BIOS load optimized...
(safe load 700-700mV, optimized 900-900mV CPU and PCIE clock drive)

Run AUTO mod:

It looks like your last two tests, second one for sure, may need you to manually set QPI/Vtt.

Try setting 1.3 again, but this time also try setting your own QPI/Vtt, try 1.15-1.24
