No FPS increase with my overclock

[broganthebro]

I recently bought a dell gaming desktop . I overclocked my experience 580 8gb using afterburner from 1266 core clock to 1403 and my memory clock from 2000 to 2250 with a 18 mv increase to voltage . This is a pretty heavy overclock from what I understand . but I do not see improvements on heaven benchmark or valley benchmark . It’s virtually the same . maybe the FPS is a .2 better lol it’s dell gaming desktop so I know they went cheap on the Mobo . Could the Mobo be the bottle neck? If so why would it still be a stable overclock and no give me a FPS boost

I am lost . What’s going on here ?

Ryzen 7 1800x
Rx 580 8gb reference card
16gb ram 2400mhz

Thanks guys

Yes, single channel ram can loose as much as @20%performance vrs dual channel ram. It's like having a whole bunch of ppl all trying to go through the same door at the same time, vrs having 2 doors. It will definitely affect benchmarks, but how much it affects any particular game is up to the game engine itself.

If the motherboard didn't like your OC, it'd tell you and you'd suffer all kinds of instability. For most situations, the only thing that'll affect the mobo with OC is if you use a software OC like what gets included with that nice pretty motherboard button, which affects the BCLK (buss clock) which can affect transfer speeds in anything. Using a bios OC manually is always superior, even if it doesn't look like it.

Okay thanks man . I’ll look into get another stick . Even if the ram stick is 8 gbs will it still run dual channel since the other stick is 16gb ? I would get another 16gb. Stick but you guys know how the prices are now a days lol .

Maybe. The rules for dual channel are specific usually.
1) same size
2) same ic's, x256Mb, x512Mb, x1024Mb etc.
3) same layout (single or double sided etc.)

There is Flex Mode. If 2 & 3 are the same, then the 8Gb and first 8Gb of the 16Gb will run dual channel, with the remaining 8Gb as single channel. The pc will use the 2x8Gb first, so dual channel is used first, until there's a need for more than 8Gb at which time the remaining 8Gb on single channel is used. But if the ic's on the ram are different or one stick is single sided and the other is double sided, then it's bunk and the ram will all run single channel.

Almost all 8Gb sticks from any vendor are the same, just as almost all 16Gb sticks are the same, so even mixed ram stands a very high chance of dual channel compatability. But as with any mixed ram, there are no guarantees.

You'd be better off buying a full 2x8Gb single kit and selling the 1x16Gb stick since most ppl don't use up more than @12Gb anyways, having 24Gb is totally wasted cash.
