DDR3 ram with a core i7-7700k

[Guest DL__]

Hello everyone. To start,my goal is to do 4k gaming at stable 60fps max.I have a gtx 1080ti. But I need to upgrade my processor and motherboard.I want to go from an amd fx 9590 to a core i7-7700k. I have 32 gigabytes of 1866 mhz ddr3 crucial ballistix elite ram, but I found an intel motherboard that supports the i7-7700k and ddr3 ram. Will using DDR3 ram at that speed cause future titles to run poorly? Will it cause modern titles to run poorly? What instances will my ram speed affect my pc. All I want is a stable 60fps. Please help me. 

 

The motherboard I am talking about is https://www.newegg.com/Product/Product.aspx?Item=9SIAD7H5EX6547

I mean you probably want the i7-7700 because you can’t OC on that Chipset

Correct. I am not looking for overclocking. But the question is the ram speed.

You should live with the pain of ditching your current memory as you'll be capping for too much the processors potential by running it off DDR3... not to mention that Kaby Lake is compatible solely with a very specific DDR3-L memory, common DDR3 will result in dead components.

I dont think you can even run DDR3 with KabyLake, so you won't have a working system.

Ok, #1: Skylake and Kabbylake do not support regular DDR3 memory. They support DDR3L memory, which is low profile ram for laptops and compact PCs. Just because that motherboard exists, doesn't mean anyone should use it. Best case scenario, the slower ram will slow down your system and cause lag spikes in games. Worst case scenario, it could actually damage The cpu. 

#2: The i7-7700k is an overclocking chip, but that motherboard does not support overclocking, so you would be stuck at stock speeds. You should either get a 7700 non-k, or get a Z270 motherboard.

It's not really as much of a matter of the speed of your games, its more of a fact that ddr3 and new skylake/kaby lake processors "technically" CAN use ddr3, but the problem with that is you need DDR3L ram, and it's more than likely that you have standard DDR3 ram. The reason being that the new processors are designed to use DDR4 which runs at a lower voltage, so using higher-voltage DDR3 could cause problems. This is why they're only compatible with DDR3L and not the standard DDR3, since the L variant runs at a lower voltage naturally. IMO I think Intel did this so that laptops could still use ddr3 but any desktop users should really stick to DDR4 unless you already own DDR3L dimms which I'm guessing you probably don't.

[moltencrystal]

youd lose out on overclocking with the chipset, get a non k skew, and save the money. 

 

Id personally say try and sell your old system, either as parts or wholes, as ddr3 prices arnt too far off ddr4 in used amrkets, and for the future compatability would be worth it in my books

[TVwazhere]

Damn, thats so weird. Never seen a skylake mobo with only DDR3 ram slots....

 

Generally speaking, RAM speed doesnt impact gaming performance on the Intel side of CPU's, but I'm not sure about DDR3 vs DDR4 on the 7700k. I would assume it would be fine and stable.

Agree.  Don't do it.

wait ... WHAT ?

 

i did not know such a thing even existed !

 

but either way ... i'd keep using my DDR RAM if i can.

 

to me, the performance difference (if any) compared to using DDR4 would not be big enough to justify spending money on 32gb ram all over again when it can possibly be avoided 

[Vroooom]

Most of the boost in performance from haswell to skylake was due to the faster memory, so even if you can somehow use ddr3, you shouldn't. You can at least break even selling your 32GB ddr3 and buying 16gb ddr4

[AnalogCanavity]

Just get rid of the DDR3 RAM

[Guest DL__]

So ddr4 is the only solution? Also what speed of ddr4 ram should I get for 4k 60fps  gaming that does not go past 60fps but will give me smooth game play?

[Anjelllo]

If you can get the ddr3 stable @1.35volts, it’s totally safe, continued use at a higher voltage WILL kill the cpu, especially enthusiast ddr3 kits that run at 1.85 volts.

It actually does, especially Skylake on, @MageTank has done enough lecturing on me about that regard already

Get ddr4, and get a different motherboard that that one. As far as speed goes, pretty much get the fastest you can afford, the faster the better with ram. Just make sure it's compatible with whatever motherboard you choose.

you got that wrong - the L stands for "low voltage" not "low profile"

 

i have a pair of desktop sized DDR3L 1600 Ripjaws running in my brothers PC.

 

they look exactly like THIS:

 

 

and the look was the reason i bought them - my brother wanted a black and blue color theme so they run paired with a kit of DDR3 1333 ripjaws (because black heatspreaders)

Ok sweet, now I can ascend to 4k gaming. Thanks

You are correct, I typed too fast without proofreading lol. Basically, Skylake and newer can't safely supply enough voltage to DDR3 with it's much higher voltage requirements.

[dizmo]

You'd be better off grabbing an 8600k, new motherboard, selling your RAM and buying new RAM as well.

Do you really need 32GB? Do you do a lot of video or photo work?

 

Welcome to the forum!

DDR3, if not low voltage, will cause harm to components. So his RAM would end up being detrimental to the system

It's a thing, but really, it shouldn't be.

It really won't. There is zero correlation between VDIMM and CPU's dying. Intel even acknowledges this in their whitesheets. Not only that, but we now have DDR4 kits running at 1.45v XMP, and some even as high as 1.5 (4600mhz XMP's). VDIMM is supplied by the board, to the ram, it does not come into contact with the CPU at all. The only voltages you need to concern yourself in regards to CPU and memory, is VCCIO (the electrical path in to and out of your IMC) and VCCSA (your IMC and PCIe subdomain voltage). Intel was against the use of fast DDR3 XMP kits due to how high they would set those two voltages, not VDIMM.
