Hello, Does anyone have a recipe to overclock or run the G.SKILL F4-3200C14Q-64GVK at 3200MHz on a X99 Classified MOBO running an Intel Core i7 6950X CPU @ 3.00GHz? I am really not interested to overclock my CPU, but I wish to run my memory at its full speed of 3200MHz. If that means I'll need to step up my CPU to run my memory at 3200MHz, okay.
I tried to run the above memory using XMP 1 (14-14-14-34 1.35V), but my system became unstable and would not boot. It would constantly recycle. If anyone knows how to get 3200MHz on my memory please reply. Here is my system configuration: CPU: Intel Core i7 6950X CPU @ 3.00GHz CPU Cooler: Corsair Hydro Series H55 Quiet liquid CPU Cooler MOBO: EVGA X99 Classified GPU: EVGA GeForce GTX 1080 CLASSIFIED GAMING ACX 3.0 RAM: G.SKILL TridentZ Series 128GB (8 x 16GB) 288-Pin DDR4 SDRAM DDR4 3200 (PC4 25600) PSU: EVGA SuperNOVA 1200 P2 220-P2-1200-X1 80+ PLATINUM 1200W Fully Modular EVGA ECO Mode Windows Version: Microsoft Windows 10 (10.0) Professional 64-bit (Build 14393) BIOS: American Megatrends Inc. version: 2.03

Since the XMP profile didn't work, try using the same timings in "manual" mode. Also set your Ram voltages manually at the rated spec. See if that helps.

Thank you bdary for your reply. I tried manually setting my timings to the settings directly below, but my system still became unstable and would not reboot. The only stable configuration I am able to run is to let BIOS or Windows boot to set my timings at those in the below image link. Do you think perhaps I should increase my CPU BCLK from 100.0 to 125.0? That would cause me to run my CPU at 30 x 125 = 3.75 GHz. I read somewhere where that helped, but those notes were for a different CPU other than Intel Core i7 6950X. Frequency: 3200 MHzCAS# Latency (CL): 14RAS# to CAS# (tRCD): 14RAS# Precharge (tRP): 14Active to Precharge Delay (tRAS): 34(tRC): 48Voltage: 1.350 V

You should be able to run 3200MHz ram with a 100 Bclk typically. When you set your timings and frequency manually, did you also set your Dimm voltages manually? If so, here's a couple things you can try. 1. Try manually setting frequency to 2666. Timings and Dimm voltages to ram spec. 14,14,14,34 & 1.35v. See if you're able to boot with that. 2. Remove 4 sticks of ram leaving only slots 1,3,5 & 7 populated. Set your xmp profile to profile #1. See if that works. Trying to run 128GB of memory at 3200MHz, may be difficult. We'll see what happens after you try these things.

Well there has been some improvement in my system performance. I see where you are going, so I set my frequency to 2933 MHz and voltage to 1.340 V. The specs say the memory is rated to run at a stock setting of 1.350 V, but I saw that the BIOS had it running at 1.370 V even though I set it to 1.350 V. So I set the voltage a little less than specs. Taking the next step, I then set the frequency to 3000 MHz and voltage to 1.350 V. But even though I am able to boot to Windows 10, Windows 10 gave me a BSOD stating it could not find the kernel. I saw that others also mentioned hitting the wall (BSOD) at 3000 MHz on the X99 MOBO. I've attached a screenshot of CPU-Z memory and SPD tabs below. I think I'll run my 128 GBs of memory at 2933 MHz, 1.340 V and timings of 14-14-14-34. Unless you advise otherwise? I wish to thank you. With your good advise you gave me the confidence to explore. I am going to run a few stability tests with AIDA64 and some benchmarks to see if everything is okay.

Okay, I spoke too soon. I had to bring down my frequency from 2933 MHz to what you recommended 2667 MHz. I had a boot recycle at 2933 MHz. I believe (hope) my system is more stable. Later, I'll try walking up the frequency to say 2850 MHz or about. After the holidays I'll call g.skill and see if they know a sure-shot recipe to have me run at 3200 MHz.

How's the 2666/7 working out? I'll be interested to hear what G.Skill has to say or recommend. Hope you'll keep me posted... On your Dimm voltage, you may be seeing 1.37v when setting manually to 1.35v because your system is deteriming it needs it. It's hard to say what it's really running at exactly based on the BIOS or software, but I'm believe it's pretty close. You could also try loosening the timings a bit and try again using 3200MHz freq. Maybe 15,15,15,36. Just to see if you can get stable at 3200.

I'll let you know any recommendations G.Skill advises. Thank you for mentioning loose timings. I did not think of that, so, in other words, there is more advantage in reaching for 3200 MHz with loose timings than maintaining tight trimmings. That makes sense, and I'll try it in a day or two. I tried 14-14-14-34-2N (tCAS-tRC-tRP-tRAS-tCR) at 1.350V and 2667 MHz but I lost 10 points of my Intel® Extreme Tuning Utility benchmark. It seems I get a little better performance with 15-15-15-36-2N at 1.230V on the DIMMs and 2134 MHz on the freq. Okay, so my next try is with 15-15-15-36-2N (tCAS-tRC-tRP-tRAS-tCR) at 1.350V and 3600 MHz.

Have you tried seeing if ONE kit by itself is able to run fine? Ie: only use 64GB of RAM? Do you even really NEED more than that? If one set of RAM (4x16GB) works at 3200mhz, I'd personally sell/return the other set (considering they're $450 a piece) and buy a better cooler. When you start using & stressing your CPU, your temps are going to be sky-high with the H55. Overclocking your CPU to make your RAM more stable wouldn't be that feasible due to temperatures on your CPU because of the increase in clock speed and voltage.

I suggested this in post #4, but he has his mind set on running all 128GB for whatever reason. His decision. But I agree that he should try a single kit 1st just to verify it runs stable at the rated specs. Sometimes combining kits works ok, and sometimes not so much. He also mentioned in his OP that he isn't interested in OC'ing the CPU. It may only be needed if he has to use a higher than 100MHz bclk which he won't if he runs 2666 (or lower) or 3200.
