Originally, I had the Intel I7 3930k at stock speeds, with 4x4GB ddr3-1600 sticks in the Intel DX79SI. Everything looked fine in CPU-Z. I just got some more RAM, another 6x4GB DDR3-1600 sticks (only put in 4 of the sticks) so I have a total of 8 sticks in the RAM slots. I'm looking at CPU-Z, and for the Memory tab, it says:
Everything else in that tab is blank. What does that mean? In the bios, I went in and manually set the timings to the correct 1.5V 1600MHZ, 9-9-9-24, but it still has the blank tab.
Also, when I go into the SPD tab, Slots 1 and 2 have the old RAM listed, with correct stuff, but tabs 3 and 4 have the new RAM, but it says PC3-10700H (667 MHZ) under Max Bandwidth. Shouldn't that say PC3-12800 (800MHz) like the old one, since it has the same specs on the box?
Finally, slots 5-8 are blank, even though they are filled.
2x4gb GSkill Ripjaw X DDR3-1600
2x4gb GSkill Sniper DDR3-1600
These four sticks worked fine; CPU-Z recognized them all and everything.
I added 4x4gb Corsair Vengeance DDR3-1600
The timings and voltages are the same, checked in the bios, but once I added the corsair, CPU-Z won't how me the timings. It still recognizes it as quad channel with 32gb of RAM, but won't show the timings.
I don't know where to find if these were tested. Intel shows me a list of module makers, but the boxes for the RAM doesn't show them. I have the DX79SI.
First, CPU-z has a limitation of (5; #1-5) or (4 ; #1-4) DIMM Slots of info under 'SPD' depending on the CPU-z version, so slots #6-8 or #5-8 will be all blank. Second you're mix-matching RAM. I'd be thrilled your PC runs.
So you mixed two Dual Channel kits of G.SKILL Ripjaw X & Sniper, then 6x4GB DDR3-1600 a Tri Channel kit?!
I have two kits of the same exact 4x4GB Quad Channel kits and as I mentioned everything show's up fine except slots #(5)-6-8 under 'SPD'.
I've never had a problem with mixing RAM, but that's what I thought might have been the problem.
Lucky boy, you must be doing something right. I'd run Memtest overnight if not for 24 hours before I concluded 'everything is alright.' All RAM throws errors, or about 1-2 per month; mixing and/or exceeding the CPU's IMC only adds to them.
