Hi Guys first of all thanks to duckie and gonX for let me open this thread. I think is better this way to find good information about DDR4 and as I see lot of people using G.SKILL i asked for it.

So i will start showing some of my results that where not intended to Bench but to have a Strong 24/7

This is my kit G.SKILL 4x4GB 3000C15 2T 1.35V







G.SKILL's behave perfect since the very first start on my ASUS R5E mobo, just setting XMP will do what is needed, but i was impressed that with a little bit of tweaking i could achieve 3100C15 1T at 1.35 wich is stock, i saw other reviews that ppl couldn't do it. Yes i took me some days to figure out, but certnaily they cand do it and more if you want to bench. For this reason i opened this thread to show what can be done, it's a retail kit from the egg nothing binned or special.

Here are the specs of my system and a picture

5930K 46.5HT 6c/12th
ASUS R5E BIOS 0802
G.SKILL DDR4 4x4GB 3000C15 2T@ 3100C15 1T (stock 1.35volts)
2x 1TB Samsung EVO 840 SSD
1x 3TB HDD
3x SLI GALAX GTX780 HOF (soon 3x GALAX 980HOF)
SEASONIC P-1200
All Water Cooled



My 24/7 Numbers wich i'm proud of them

If i have a gskill 2666 c15 kit currently clocked at 3000 at 14 15 15 35 would that be an issue.....i find that to be the only stable clock i can achieve

14 14 15 38 was a tad bit shady as sometimes everything is fine other times it just plain acts wierd.

Is having a cas 14 followed by 15's instead of 14's good practice ?

1T or 2T bro ???

3000C15-15-15-35 2T should be a nice spot or 1T but id you lower 14-15 it will ask you for more and honestly o dont't see that difference. I use 3100C15 1T as you saw.

Best regards !!!

Right now im balancing out at 1.355 but i have a few issues of my own balancing out my cache at 4.3ghz and clock at 4.5

Tho its 100% stable in every single test out there except prime 95 which crashes pretty much everytime....not sure if im just chasing my tail on this one.

Right now my stats are
cpu input:1.94
Strap 125 base multi of 36
cache of 34 multi

Cpu over...voltage 1.284
cpu cache at 1.284

Dram at 1.355

Sytem agent at 1.16......<< this is what im not sure of how far is my tolerance range.......

Oh and command rate for my ram is 1T...... solid

If i did a usb boot up of memtest would it be as good as running all those millions of different iterations of it in the os ?

1.355V is really good. You can try lower system agent v to where your cpu's imc can be stabil enough.

Try this Hyper Pi 0.98b https://www.asuswebstorage.com/navigate/s/07FA39C236CD4C3885423B279E87C1A64

Good multi cores stability test for ram and cpu without excessive load on the system.

So just ran memtest for 24hrs and all passed without any errors.....might try to raise my ram to 3100 like you guys ut just looks cooler lol jk

Funny thing is my cpu just doesnt want to hit anything about 4.5 stabile lol with i mean i can 4.7 but i wouldnt dare even try to do a stability test lol

cyberlando bro no need 24hs of MEMTEST just let it pass to 300% and thats all

Kits will react different because no kit is equal to other like CPU neither, so you have to test and learn trying also EVENTUAL DRAM VOLTS, and remember the more you tight or go up in MHZ, CPU will ask for more food

What system agent voltage are you guys using....idk why but seems that this db q code is a real issue around the net for the x99

Many people say no matter what stress test they do they can never crash their os but still randomly there pc fails to boot first time randomly.....
