Have the 16Gb 3600 16-16-16-36 kit running fine at XMP.

Just dialling in my PC tune before leaving it. CPU is happy at max OC of 5ghz (8600k).

What can I potentially do with this memory, it's been a long time since I've overclocked ram.

Do I manually force it to run at higher MHz? If so what range can I hope to attain ?

At what point will I have to loosen timings and how do I go about adjusting them?

When will higher frequency be of benefit and when will tighter timings be of benefit (to gaming)?

Does voltage need to be changed?

Or if 8pack can chime in are there any relatively 'safe' fire and forget settings I can try that you'd expect most ram kits to be able to achieve?

I know at this point it's probably icing on the cake but I'm playing PUBg a lot and the Tesco mantra is definitely true!

Cheers:)
 
Ok so I got it running at 4000Mhz (1.4v), anything higher the board will not boot properly. Would not do CAS 18 but works at CAS 19.

Remaining clocks at 20-20-44.

Small lift in AIDA64 throughput.

Should I leave command rate at 2T?

Cheers

Edit: memtest gave errors on test six. Shall I try upping to 1.45V? Would like to get 4000Mhz stable if possible it's just a 'round' number hehe:) or any other things to try changing?

Didn't know that about dropping CPU to stock when testing RAM. I take it memtest is still a gold standard for checking stability?

You mean go to a 1:1 FSB DRAM ratio?

3900Mhz was stable on four passes in memtest, just gotta get that 4000Mhz!

Edit: memory is able to do 4000Mhz but needs the 1.45V, how am I with warranty on that clock and volts 24/7?

Is this speed bump only Good for my system i.e. can any games perform worse with higher frequencies and looser timings? Playing PUBG last night at 3900Mhz dunno if imagining but seemed a bit less perf than usual.

Ive been messing with my Ram trying to clock them as well. We have similar systems, i got 8600k and Team Xtreem 3733mhz modules. Ive found that utter speed is not the benefit. As sub timings get very loose. I did manage 4ghz on mine with 1.45V but the performance has dipped on benchmarks, so ive been back at 3733mhz and fine tuning and its running really well.

Im now 16-15-15-28 @ 3733mhz
 
There's articles and videos where RAM SPEED benefited PUBG. Like I said in game i wasn't noticing the difference myself but I've yet to do reliable objective testing.

I might see how fast the modules will go with stock timings at 1.45V, any hunches 8-Pack?
