Is uneven memory timings bad for performance?

[orangecat]

I'm currently overclocking my ram and I wanted to know if it's a bad idea to have uneven memory timings. Currently my timings are 11-12-11-26 and I'm lowering them one at a time until it can pass memtestx86. I so far have been able to get my memory stable up to 2400Mhz but since performance is what I'm going for I want to make sure my timings are as low as possible.

My kits XMP profile is nothing special it's just a 8GB kit of 1600Mhz 9-9-9-24 1.5v DDR3.

Also to any experienced memory overclockers what timings are most important? I have a general idea of what is good settings but I don't know 100%.

Why overclock? You probably won't see a huge gain in any gaming or rendering times.

 

Edit: Especially since it's just a simple 8gb 1600mhz kit. That's just wasted power to me.

There are gains definitely, they just aren't big ones like with CPU or GPU OC's.  Although depending on the game, gains can be big when the game is primarily CPU intensive, things like LoL / most MMO's, starcraft etc.

What volts are you using?  TRFC is another one you can lower a lot to get a tiny bit extra performance.

 

Also going from 2T to 1T command rate can help.

Never said there weren't gains. They just aren't huge. Not worth it IMHO.

Free performance is free performance :]

The gains are actually quite large when running 2 GPU's, probably due to more driver calls etc. (Although 1 game tested is kinda "eh")

Well I do sometimes use my integrated GPU but I'm not concerned with power draw.

I'm currently at 1.7v and I'll try lowering the command rate. I plan on dropping the voltage a bit of I can but 1.7 isn't going to hurt anything.

Thanks for the feedback.

Yeah 1.7v is fine, I regularly go to 2.1v on my kit for 2800 9-12-12-18 for benchmarking on hwbot.

(although i have samsung memory chips, which can handle a crapton of volts on air without damage occuring)

See if your bios lets you change your RTL timings, sometimes auto setting sets em way to high.

I don't remember what they should be at for 2400 mhz, i think 37 for A channel and 38 for B channel (might be higher might be lower)

Alright I'll check my RTL timings, my bios also has pretty much every memory timing you could ever want to change but I don't think I'm going to go crazy with some of the secondary timings as I'm not exactly sure what all of them do.
