Stability issues with TW3X4G1600C9D on Asus P5Q3 Deluxe Wifi

Hello everyone.

I just upgraded my RAM two days ago (sunday)

From ******** EM Series DDR3 2GB 1333 dual channel to Corsair Dominator DDR3 4GB 1600 dual channel (TW3X4G1600C9D, listed spec at label, 1600Mhz, 9-9-9-24, 1.8v, Rev 3.2).

 

Now, I want to explain what I've experienced and asking for the best solution to fix my problems.

 

1. the system are unstable (random crash, freeze) when I ran the memory at 1600 (9-9-9-24, 1.8v / auto). The system also unstable even at 1333 (9-9-9-24, voltage auto). I never experienced this before with my previous memory module.

 

2. I've run memtest to check whether I got bad modules, but memtest showing zero error. I ran the test with both module inserted on orange slots.

 

3. Tried to run Prime95 for an hour or more, also didn't crash the system (strange huh).

 

4. SIW and also CPUZ, showed my memory module not listed as TW3X4G1600C9D but like these

My current bios revision is 2105 (which is the latest from asus support)

 

What should I do to make my system stable? my target is to have 4gig system that stable at 24/7 because I mainly use this system for rendering.

 

Please help me guys....

 

Also, can Core i5/i7 (P55) designed memory works with my chipset (P45) ?

The memory isn't designed for the platform.

 

what do you mean by that... even Corsair CONFIGURATOR showed TW3X4G1600C9D are compatible with my motherboard / platform...

I already fixed the stability issue by running the memory at 1333 with latency 9-9-9-24, 1.7v

 

been running without any problem for almost 24hour. I hope there will be no freeze / crash in the next 7 days... :D

 

but still... a bit disappointed because I can't run the memory at 1600 9-9-9-24 1.8v (standard spec for TW3X4G1600C9D)

With Intel Chipsets you cannot run the memory faster than the CPU FSB, so with the CPU that you have listed the fastest you could run the memory would be DDR1333. This is a chipset limitation not a memory issue.

You stated:

That statement is incorrect. They did not "design" it for that platform. That's a different statement than saying it's only compatible with a Core i5/i7 system.

 

Having said that, if you want to hit 1600, you've gotta OC your FSB.

i see. so I should bought DDR-1333 instead 1600... ahh...
