Because gullible people buy it.
A few benchers buy high speed RAM, but not nearly as many as people with more money than sense
There's some talk about a higher minimum FPS (and overall) in gaming with faster speeds, but it's pretty small. Just people looking for the extra oomph.
Personally I got 2133 on the cheap, might as well run at those speeds. I got 8GB of 2133 at 2133, and 16GB of 2133 running at 2200 10-12-12-34. I ran that at 2400 for a while, but I was having some board issues where it wouldn't boot correctly.
I guess. If I ever had a crash (like in BF4), it wouldn't reboot properly. Had to shut off the PSU and turn it back on... sometimes I had to play the RAM shuffle to get it to boot at default speeds and just reapply the settings. Plus I think I was running at CL11. Not worth my time. With 2200 I have none of those issues.
Prior to that I was running 1600 9-9-9-24. Can't say that I've noticed any significant difference.
Prime95 Blend also tests RAM, that's probably causing the lock.
Maybe, but it's been running Prime blend for over 1 hour now, no issues.
So that LLC seemed to have fixed that issue.
Question is, should I lave it on medium or set it to high or something?
Cpu-z reports Vcore of 1.116 but I set Vcore in BIOS to 1.16.....
Sounds like you're dealing with a hell of a lot of vDrop (voltage Drop from what you are setting in BIOS and what it is actually giving you). Are you showing 1.116 at idle or load (should be a different voltage under load vs. idle).
Load.
I went ahead and set the LLC to High, now CPU-Z reports 1.14 Vcore much closer to the 1.16 I set in the BIOS.
The next step is (turbo?) or extreme
EDIT: Actually it bounces around from 1.128 Volts to 1.14 volts now
And while idle, Vcore bounces around from 1.15 to 1.52 volts.
Well the difference in load voltage is pretty good (0.012V). I don't usually see much better than 0.02-0.03V on most PC's I run, and around 0.05-0.06V at worst (no LLC option on the board).
You say it's bouncing between 1.15 and 1.52V at idle though?
It shouldn't be anywhere near 1.52V when it's set to 1.16V. That's just odd. Unless that was a typo.
I would set LLC to extreme and lower your core volts so CPU-Z shows 1.14-1.15v load and idle and try and lower voltage from there you have such a small increment overclock you should not need that much voltage.
Ok that is good then you can go up to 1.28v with no problem.
Okay I'm back
I set the Vcore to 1.14 in the BIOS, and
I set the PLL to "Turbo" (next step is extreme)
@ idle bounces between 1.128 and 1.14
While folding, it'll stay at 1.128 volts
Under Prime95 blend it stays at 1.14
