I just sent this to GSkill tech support and if anyone has an idea why my PC-12800 Rip-Jaw ram is showing up in CPUID as PC-10700 let me know.
I own 3 sticks of F3-12800CL9-4GBRL in triple channel mode on a Gigabyte GA X58-UD7 REV 2 board which is water cooled. When looking at CPUID, this ram is listed as PC-10700 (667mhz) I have been running this completely stable at 1600 9-9-9-25-40 2t, but I am worried that this was miss-labeled ram as 10700 ram is usually slower than 12800, and CPUID is usually not wrong when it reads SPD info from the sticks.
I just purchased 3 new sticks of GSkill Sniper from Newegg which are F3-12800CL9T-12GBSR2 which is rated at 1600 9-9-9-24- at 1.25v and this is ultra low voltage ram. The lowest voltage I can set this ram at in my bios is 1.35 v but I cannot find any setting that is stable except jedec 2 which is 533 (or 1066) and in most cases, it will not even post or it runs for a short time at 1600 then crashes. I have tried 1.5 v same exact results. I put the Ripj-aws back in, and it runs perfectly stable at 1600. (no posting problems). I have run this same ram for some time at 1800 with almost complete stability, but I backed it down when I noticed the CPUID SPD value being 10700 vs 12800 like the label on the spreaders
1.Are the Rip-jaws mislabeled on the heat-spreader? (is it really is 10700, but runs stably over-clocked at 1600)
2. Are the Snipers just incompatible with my board, or a bad batch. I am going to test in a newer UEFI board and see if 2 sticks of this will run stable in dual channel.
If I find unstable in the newer board should I RMA? I have attached a screen print of the part number miss-match on the Rip jaws. (not included in this forum post)
BTW the Snipers show the higher max bandwidth in the SPD window that matches 12800 label on the plastic spreaders, but they are totally unstable at 1600, rated voltage or higher.
