Did I just downgrade my RAM by accident?

Hi

I do art for video games to make living and I've recently been having very slow performance from my machine so I thought I'd look at upgrading some bits. I typically have Visual Studio, Unreal Engine 4 Editor, Maya, Photoshop, 3/4 Windows image previewer windows, 4/5 windows explorer windows, around 8 tabs of Chrome and will then run the game I am working on at the same time.

My pre-upgrade specs were:

Intel Core i5 2500K @ 3.30GHz Sandy Bridge
Gigabyte Z68X-UD5-B3 MoBo
ATI Radeon HD 6970
Kingston HyperX Genesis Grey 8GB (2x4GB) DDR3 PC3-12800 C9 1600MHz
Crucial CT128M4SSD2 128GB M4 SATA III
Hitachi Deskstar 7K3000 HDS723030ALA640 - Hard Drive - 3 TB - SATA-600

I've since bought:

4095MB NVIDIA GeForce GTX 970 (PNY)
Kingston HyperX Savage 16 GB (2x8GB) DDR3 2400 MHz DDR3 CL11

The graphics card seems like a straight forward no brainer upgrade but I've been looking in to the ram and I'm now thinking I may have wasted my money?

My new ram is supposed to run at 1.6v but apparently the maximum voltage recommended for my CPU is 1.52v. I read somewhere that underclocking the ram and reducing the voltage to it is OK to do and it will just run at the fastest speed it can with the voltage. So I thought, "cool, I'll just future proof my machine and ramp up the voltage in the future when it's time to get a new moBo/CPU" but from what I can tell the fact the CL on the new ram is high at 11 it might actually make it slower than my old stuff and also cause instability with the CPU/MoBo?

I know a lot of people are advised that they don't need 16 GB of ram but I think I maybe be an exception because my day to day work relies so heavily on the use of multiple resource hungry programs simultaneously.

Thanks for making it this far.

Cheers,
D~

 
CL = CAS Latency, in clock cycles. Your new RAM is way higher frequency than the old RAM (even if you have to drop it to ~2133MT/s), so each clock cycle is shorted. Although it's more clock cycles, it will be less actual time.

I'd actually look at more RAM. That's a lot of memory-intensive programs. I'd suggest maxing it out to 32GiB.

8GiB is the sweet spot for running current games and nothing else. Just having photoshop usage would be enough for me to suggest 16GiB.

Hi,

Thanks for your response.

Any chance you could advise me what settings I should use in the BIOS? I'd really rather avoid damaging the CPU is I can and if I use the XMP it will set the voltage too high right?

I'll definitely consider more RAM, my board has the slots for it.
