Is my motherboard faulty or...

Alright, I won't spill every detail here as I've been discussing my problems (BSODs and crashes) with my newly-built computer on sevenforums.

BUT, I'm curious if my motherboard could be faulty or my RAM.

**SYSTEM SPECS**
OS: Windows 7 Home Premium SP1 64bit
CPU: Intel Core i5-3570K @ 3.40GHz 3.80GHz
MoBo: GIGABYTE GA-Z77X-UP4 TH (REV 1.0)
Memory: 8.00 GB (2x4) Patriot Memory - Viper DDR3 @ 1600MHz (PV38G160C9K)
GPU: NVIDIA GeForce GTX 660
PSU: CORSAIR CX600 600W ATX12V v2.3
Case: NZXT Phantom 410 (white)
Cooling: COOLER MASTER Hyper 212 EVO
SSD: Samsung SSD 850 PRO Seri
HDD: ST31000524AS

I tested both RAM modules in Dual Channel and each one individually in Single Channel through Memtest86. Went through 10 passes with 0 errors while Dual Channeling and did 1 pass with 0 errors when testing each stick individually on each slot.

My main concern is that when testing the sticks individually, DDR3_1 and DDR3_3 slots will read each RAM's CAS latency as 6-6-6-20. DDR3_2 and DDR3_4 read as 9-9-9-24 which is what they should be.

To further investigate I got the SPD and Memory readings for each individual stick via CPU-Z and they read 9-9-9-24.











Any ideas if there's something actually wrong with the MoBo / RAM?

If it helps... here's my two threads for reference to my issues on sevenforums BSOD problems and RAM concern

Would greatly appreciate some feedback :)

Hello... set your Command Rate of your Ram in the Bios to 3T... as your Ram Specs are read and defined in the CPU-Z snap shot.

Alright, but if I'm understanding you correctly you want me to change the CR to 3T while running on single RAM module at the moment? After doing so, what result should I be looking for? Thx

I checked the BIOS and found that there is a Channel A Command Rate which is set to Auto and a Channel B Command Rate set to 1T. So I'm not entirely sure which one to change. I left it as is for now.

Hello... the "Command Rate" is How many "CPU cycles" of time, is allowed to find the data stored in your RAM... 1T is concidered very aggressive... 2T is pretty standard setting in my Past computers, in order to have " no memory errors", and higherFSB setting for my CPU.

So i'm suggesting a setting of AUTO for you... OR try 2T - 3T to determine if there is a memory problem.
