Recently my step father wanted a computer built for him. So, I configured a 4770 system, and purchased some Vengeance 1600MHz C9 RAM. After Windows was installed I paid attention to the POST screen and noticed the RAM was only at 1333MHz. I used the UEFI to check the SPD and noticed that the timings were JEDEC up to 1333MHz and that 1600MHZ was only capable when using the XMP; which has worse timings (C10/2T). I order a completely different set of Vengeance C10 RAM from Corsair and the same timings were configured; JEDEC 1333MHz (1T) and XMP1600MHz (2T).
Now the interesting thing is this. You pay for lower latency C9 RAM at 1600MHz but the memory can only be used in C10/2T timings! Only when the JEDEC 1333MHz SPD timing are used will the RAM be at C9 and 1T timings. I called Newegg, and spoke with a “Product Support” rep. He said all 1600MHz is configured this way on 1150 motherboards. I told him this is incorrect. There is a standard timing for 1600MHz and that the RAM is not true 1600MHZ supporting RAM. I also informed him of my Corsair RAM that I purchased for my 3770 about a few years ago is JEDEC 1600MHz C10 1T (XMP 1600MHz C10 2T), and is a perfect example of what I am arguing about.
He wanted me to flash the UEFI again, which is unnecessary. Even contact Asus for suport, which is not the root of the problem in my opinion. I informed him that the problem is the RAM and how it is configured to not be JEDEC 1600MHz RAM.
If my argument is correct I will NEVER buy Corsair products again; and neither should you. If I am wrong, then does the issue lie truly with Asus' firmware reading the SPD? But how can this be so if the SPD is configured as a lesser and not to JEDEC standards for 1600MHz?
Any rebuttals, thoughts?
