Welcome to GIGABYTE Technical Support!

[TheQCC]

There are four memory modules in my computer. They are Kingston Value Memory KVR1066D3N7 2GB.
CPUID reports them as triple channel.
The Gigabyte motherboard manual indicates it supports four triple channel modules.

Memtest86+ 2.11 passes the modules with these settings:
Memory 616MHz (1232MHz), BClk 154MHz, QPI 5.5GT/s, CAS 7-7-7-20.
The above apparently are the Easy Tuner 6 Turbo settings.

When Easy Tuner is set to "Full throttle" mode, Memtest86+ almost immediately reports errors and halts.
These are the settings reported by MemTest86+ for the Full Throttle mode.
Memory 636MHz (1272MHz), BClk 159MHz, QPI 5.7GT/s, CAS 7-7-7-20.

So my conclusion would be the memory cannot go that fast or there is a flaky memory module at the slightly elevated speed.

I will attempt to get the computer store to replace the memory modules and run Memtest86+ again. Returning them with a RMA is not an option. That would result in no computer for two to three weeks.

Thanks.

Have you tried removing the module from the blue slot?

I found this info to the Gigabyte's memory support list for your motherboard above and below.
GIGABYTE - Product - Motherboard - Overview - GA-EX58-UD3R (rev. 1.0)
It shows Kingston KVR1066D3N7/2G in the memory support list but triple channel of the Kingston KVR1066D3N7/2G shows 3 pcs. Not 4 pcs. Only a few brands on Gigabytes list will support triple channel with 4 pcs. Please check the pdf files for memory support list page 3. I believe this is the issue you are having.

OK. After removing one stick of the Kingston 2GB Value Ram 1066, triple channel DDR3, my conclusions have not changed.

I removed the stick from the Blue slot and performed a MemTest86+ (v2.1.1) with the CIA2 set to Full Throttle.
MemTest86+ reports these settings:
Memory 636MHz (1272MHz), BClk 159MHz, QPI 5.7GT/s, CAS 7-7-7-20.
No voltages were changed from stock as far as I know. I do not know if the Easy Tuner 6 CIA2 option changes any voltages.

MemTest86+ ran for 22 seconds and halted.
I rotated the memory through the three white slots. Still 6GB.
Ran Memtest again. Halted after 1 minute.
I rotated the memory through the three white slots, again. Still 6GB.
Ran Memtest again. Halted after 30 seconds.
Conclusion:
The Kingston memory, KVR1066D3N7/2G, is not stable at the Easy Tuner 6 CIA2 settings of "Full throttle"
I have left the memory at 6GB and selected the "Turbo" setting.

A new page in the story has now been written by the Gigabyte GA EX-58 UD3R motherboard.
Occasionally, the computer does not boot, but halts with a boot failure message due to overclocking or voltage settings. The default i7-920 settings are displayed.
Press any key to continue.
The system then starts up "normally".

This boot message only occurs form a cold start, not a re-start.

I have updated the BIOS to F6. The official version, not the Beta.
This may be a new feature of the BIOS.

QCC Kingston KVR1066D3N7/2G has plenty of features. You can tweak the Mhz when you loosen the timings up a little. (CAS 7-7-7-20 to 7-7-7-21, 7-7-7-24, 8-8-8-24, or 7-8-8-23) You may need to make adjustments to these to find a good overclock. Also the voltage may need to be changed from 1.5v to 1.55v. Be careful when raising voltage, try to stay within range to not void your warranty. A very little voltage increase usually will suffice to ensure a stable overclock, but may, or may not be needed.
FEATURES:
JEDEC standard 1.5V ± 0.075V Power Supply
VDDQ = 1.5V ± 0.075V
533MHz fCK for 1066Mb/sec/pin
8 independent internal bank
Programmable CAS Latency: 5,6,7,8,9,10
Posted CAS
Programmable Additive Latency: 0, CL - 2, or CL - 1 clock
Programmable CAS Write Latency(CWL) = 7(DDR3-1066)
8-bit pre-fetch
Burst Length: 8 (Interleave without any limit, sequential with starting address “000” only), 4 with tCCD = 4
which does not allow seamless read or write [either on the fly using A12 or MRS]
Bi-directional Differential Data Strobe
Internal(self) calibration : Internal self calibration through ZQ pin (RZQ : 240 ohm ± 1%)
On Die Termination using ODT pin
Average Refresh Period 7.8us at lower then TCASE 85°C, 3.9us at 85°C < TCASE . 95°C
Asynchronous Reset
1066Mbps CL7 doesn’t have backward compatibility with 800Mbps CL5
PCB : Height 1.180” (30.00mm), double sided component

I will try your settings and report back.

Update:
I selected the CIA setting of "Full throttle" and manually set the memory timing to 7-7-7-21. with 6GB of Kingston Value RAM DDR3 triple channel memory.
I ran Memtest86+ (V2.11) and it reported these settings:
Memory 649MHz (DDR3 -1298MHz), BClk 162MHz, QOI 5.8GT/s.
Memtest86+ ran for 2' 21"' before it just halted.
I re-booted and got the BIOS boot failure message and when it stated the settings were basic i7-920 defaults.
As suggested, I increased the memory voltage to the next highest setting. 1.54 V and restarted Memtest86+
The Kingston memory passed one complete pass of Memtest86+ with 1.54V.

Satisfied that my expectations were met, I just wanted the computer to run at the installed features, I started Windows XP Pro x64.
To check the system, I started CoreTemp 0.99.5 and monitored the temperatures at idle. The average core temp was 35°C.
After 20 minutes of idle I started Prime95 with its core and RAM test. After 30 minutes of 100% load, the average core temperature is 70°C.

It would appear as though the Kingston Value RAM can indeed run with the "Full throttle" setting with just a bit of voltage boost.
This harks back to my original post: What are the values used by the CIA performance options?
Probably, even if I had known them, I still would not have known to adjust the voltage upwards.

Thank you very much for your suggestions.

Hi, I've been having some problems with a ga-ep45-ud3p board and was hoping to get a second opinion and viewpoint. My system is: Gigabyte ga-ep455-ud3p, Intel core 2 duo E7300, ATI radeon 3850 256mb, 700w OCZ power supply and 8gb(4x2gb) ocz reaper ddr2 8500 @ 5-5-5-18 2.2v. My problem is that the system does not like having more than one stick of ram at a time; it'll post i can access the bios and occasionally get into my operating system however it is continually unstable and crashes. Easy tune is set to default, I have the latest bios (f9) installed and the system is staying cool. When I try to run memtest-86 v 3.5 with 4 sticks of ram the system crashes within seconds with one stick it seems to chug through it. I thought the ram might be bad so I also tried some Crucial Ballistix tracers (ddr2 6400 4-4-4-12 @2.2ghz [4x 1gb]), however they responded the same way in memtest i double checked the ram and it worked beautifully for 6hours on another machine in memtest. this leads me to believe there might be a problem with the motherboard and i was hoping for some input on the situation.
Sincere Thanks.

Grudairian you may want to go to bios and be sure the memory voltage and timings are 5-5-5-18 2.2v and not on auto.
If you do not find the settings you want in the Main Menu or a submenu, press Ctrl + F1
to access more advanced options when initially going to bios (On the main menu). Then go to MB Intelligent Tweaker (M.I.T.) I wish I had your memory part numbers Gigabytes supported memory list only shows OCZ2N1066SR2GK. This only means that this is one of the many modules they tested and support. If your dram voltage is set on auto you will need to change this, and make it equal 2.2v and also change your timings to 5-5-5-18. If it is set in bios correct then contact Gigabyte’s technical support at :

I would suggest you setup your memory manually in the BIOS, using Easytune to SAVE Settings, or even to apply settings or overclock, may not ever get things correct same as Auto BIOS values

Hello guys, I need your help :)
I have this motherboard GA-MA790X-DS4 for more than 1 year now, and suddenly (my last 3 reinstalls) when I install windows (when he check and install devices) my internal speaker starts to beep. First beeps for 2-3 seconds with some pause, then the beep is longer till he don't stop (only after 10 min or so) then the setup continue and the install is completed. Can someone give me some advice how to fix this? I'm sure it's not ok.
My setup: (I've added AIDA32 report aswell)
-Motherboard: GA-MA790X-DS4
-Processor: AMD Phenom(tm) 9500 Quad-Core
-Video card: ATI Radeon HD 3850
-Storage: WDC WD2500JS
-OS: Microsoft Windows XP Professional 5.1.2600

Thanks in advance.

I am sure others who are more familiar with your motherboard will have more specific advice.
When Windows is installed, it tests the hardware. This testing may cause the hardware to react and sound an alarm. The alarm is an indication a device driver is required and was not installed.
After the Windows XP Pro installation, have you installed the motherboard drivers from the Gigabyte CD, ATI display drivers?
If no, then do so now.
If yes, then open the Windows Device manager. (Control Panel, System, Hardware, Device manager) and check for an "other devices" listing and any device with an exclamation mark beside it.
Install the drivers needed for the indicated device.
