2 kits of TW3X4G1333C9A

I am having the same issue as mentioned in other threads... 2x TW3X4G1333C9A G, Intel Board (DH55HC) with a core i5-650. 4gb works fine, add the other 4gb though and i get random reboots in Windows 7 x64.

 

I have not yet tried to underclock the memory.

 

Recap:

- All Memory tests pass on Windows Memory Test (boot cd) 1 stick at a time

- System will boot with default timings with 4gb of ram installed (2 sticks),m reboots after being in windows for more than a few seconds/minutes, or opening a program.

- system will boot with suggested 9-9-9-24-1T (can't seem to figure out how to do 2T) with 4GB (2 sticks) but reboots when entering windows with 8GB.

I would recommend testing each kit individually and if both kits pass then it would suggest an issue with the memory controller. At which point I would try setting the timings to 9-9-9-24-2T and the memory voltage to 1.6v and slow the memory frequency down to 1066MHz.

Windows won't even boot with the settings you suggested. It gets to the "starting windows" logo screen then reboots when it attempt to launch into the desktop.

 

It boots and runs with no issues with 4gb of ram. With 8, it crashes (more frequently with these setting than with the originals).

 

Please note, I did test all the memory modules individually and they seem fine (no errors).

 

Below are pictures of the RAM and of my BIOS settings.

The BIOS shows that each module is recognized. I've already tried re-seating the CPU.

 

I suppose I should have mentioned earlier: We have the SAME issue on two identical machines. We ordered them both around the same time. The both have the same internal components and both have the same issue with this RAM.

 

As this is happening on both machines. It is unlikely due to improperly seated CPU/Ram.

 

Are there other timings, etc I should try? the ones you mentioned above do not work at all.

Hi RamGuy,

 

Thanks for the reply. I'm not very knowledgeable when it comes to RAM timings & voltages, etc. Can you tell me why I want to increase the voltage to 1.6? Other threads/forums suggested leaving the voltage alone and setting the timings to 7 7 7 19 (or similar?).

because running 4 sticks is a strain on the memory controller. you need to find the 1T/2T (1N/2N on some boards) and set it to 2.

you may even have to set the speed to DDR800 to get the 2 kits to play nice. this is why running 2 kits together is not officially supported and never suggested. RG is just pointing out settings that may work for you as it is impossible to predict results with 4 sticks that were not tested together at the factory on the same board.

good luck.

a single 8 gig kit from here would have been a much better choice. http://www.corsair.com/products/corei5/default.aspx

It may not be "officially" supported, but I've never had this issue with any of our machines before. It is hard to get a 8G kit for a decent price, so people often buy 2 4G kits. Other Ram we've used in our other machines has had no issue. We have 2 core i7 machines with 12g of ram that work great (2x6G kits).

 

I'm just looking for timings/config that will allow us to run the 2 kits together. It should work. the board and CPU are rated for it, and according to Corsair's site, this kit was made for the core i3/5 family.

 

I tried changing the voltage to 1.5 from 1.6, it stayed up longer, but still reset after about 15-20 mins (idle).

 

The page you lined to does not work... the "shop online" buttons throw a JS error..

yes, with completely different ram and on an AMD platform.

i didn't mean to imply it will never work, i meant getting them to play together may be like pulling teeth from a lobster.

out of curiosity will it work with 3 slots filled? and did you find out how to change the settings to 2t?

We can certainly replace the modules if they are faulty however it sounds like you are running into an issue with the board or memory controller. Have you tried updating the board to the latest bios off of Intel's website?
