G.SKILL Trident 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600

[hoangsgp]

Hi
Please help me to solve this problem.

My Configuration:
Main GA-EP45T-DS3R
Bios Version: F3

Memory: G.SKILL Trident 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL8D-4GBTD
http://www.newegg.com/Product/Produc...82E16820231259

Processor: Intel Core 2 Duo E8400 Wolfdale 3.0GHz LGA 775 65W Dual-Core Processor
http://www.newegg.com/Product/Produc...82E16819115037

VGA card: Gigabyte HD4670

OS: Windows 7 Professional and Windows XP SP3.

My computer is not stable as it crash regularly. I set the Bios as default except DDRAM Voltage = 1.5V (althougth it appear in PC Health Ststus

DDRAM Voltage = 1.744V. I set the Ram Voltage to 1.74V, 1.72 or 1.7V then it reboot many times and can not start Windows).
As I'm not good in Computer so I do not know how to set my board to run stable. I read many threads that guide to set parameters such as DDRAM TIMINGS, Command Rated, Vcore...But it make me very confuse.
Please guide me to set these parameters correctly.

Thank in advance,

Hoang

You'll want to manually set your base timings to 8-8-8-21, DRAM voltage to 1.6, Command Rate to 2T (or 2N depending on how the BIOS displays it) and you tRFC to appr 68.

[hoangsgp]

Thanks alot. I will check whether it could get stable and post updated with performance.

[hoangsgp]

Hi Tradesman
I set parameters as your suggest (base timings to 8-8-8-21, DRAM voltage to 1.6, Command Rate to 2, tRFC = 68) and now my computer run with out any trouble. It's amazing, I show you the result from EVEREST test


Is this ok for an DDR3 12800? May I have an increase in performance? If yes, please teach me what should I adjust?

Thanks you so much.
Hoang

[Tradesman]

You can try and increase the performance....but to be honest, unless your looking for benchmark increases (bragging rights) it's probably not worth it..........UNLESS...you have some time and like to play (don't we all?)...if that's true, you'll want to document your current settings so you have a fallback position to go to if you have a failure. Next you can try playing with the base timings, your currently at 8-8-8-21, so you could try 7-8-8-24 or 8-7-7-21, etc the lower (or tighter) the numbers, will show an increase in performance....but, it's not likely to be anything you will 'see' or notice, except in benchmark scores.

Don't want to burst any bubbles, but if your thinking a noticible increase in performance you probably won't see it

[hoangsgp]

Hi Tradesman

Sorry for bothering you again. I was a bit early to say that my system was stable and was busy to ask for your help since last time. My system still crash sometimes, it not too much but sometimes it happen when I making video or burning disc.
Could u please give me some advices to clear this matter. I re-install my system some times but it did not work. I did keep my configuration as your suggest last time (base timings 8-8-8-21, DRAM voltage to 1.6, Command Rate to 2, tRFC = 68) and my OS is Window 7 Ultimate 64 bit.

Thank you so much for your help.

--------------------------------------------------------------------------------

Crash dump directory: C:\Windows\Minidump

Crash dumps are enabled on your computer.


On Fri 19/02/2010 12:51:36 CH your computer crashed
This was likely caused by the following module: ntoskrnl.exe

The crash took place in a standard Microsoft module. Your system configuration may be incorrect, possibly the culprit may be another driver on your system which cannot be identified at this time.

--------------------------------------------------------------------------------
Conclusion
--------------------------------------------------------------------------------

3 crash dumps have been found and analyzed. Note that it's not always possible to state with certainty whether a reported driver is really responsible for crashing your system or that the root cause is in another module. Nonetheless it's suggested you look for updates for the products that these drivers belong to and regularly visit Windows update or enable automatic updates for Windows. In case a piece of malfunctioning hardware is causing trouble, a search with Google on the bug check errors together with the model name and brand of your computer may help you investigate this further.

Any one can help me? Right now I can not use my desktop to do any work because of it's not stable and alway appear BOD screen.

Other than that, everything seems just fine. Try testing each one individually to determine whether one may be defective.

As I set DRAM Voltage to 1.64 V or 1.66 V, Windows work only for few minutes or even not pass through the first starting window. After few reboot with this setting (after appear BOD said about memory problem) then it even can not reboot system with sound "beep beep beep". I have to take out 1 stick and reduce DRAM Voltage to 1.6V for it to boot again. I tried test each stick individually with DRAM Voltage at 1.6V (at both slot) by Windows 7 Utility and it pass through the standard test. Now I can use only 1 set 2Gb with DRAM Voltage at 1.6 V. Please help me on what parameters need to change.

Thank you.

[GSKILL TECH]

Is that the latest BIOS for the motherboard?

Thank you
GSKILL TECH

[hoangsgp]

Yes, I use F4C version and it is the latest Bios version from Manufacturer.

Thank you.

[GSKILL TECH]

Did you test each module to make sure they are all working fine?

Thank you
GSKILL TECH

[hoangsgp]

Yes I did. I tested each of sticks individually at both slots with Windows 7 Ultility (standard mode). And all sticks pass without any problem.

Here is information I get from Everest when I use 2 DRAM at 1.6V

[GSKILL TECH]

Don't adjust anything you don't know. Simply leave to AUTO.

The main problem I see is Write Recovery Time (tWR) 20T. It should be 12T.

Thank you
