Samsung Green Ram

[8 Pack]

It seems ok to me mate. You could tune the seconds. If you want help let me know.

 

[LtMatt]

I guess ill leave the other timings at Auto 8pack unless you think its worth me doing?

Ok so im fully stable at 4.5ghz 2133 10-11-11-21-1T.

I'm almost fully stable now at 5.0ghz 2133 10-11-11-21-1T.

What has surprised me is that i had to to bump memory voltage up to 1.65 to get stable. I'm working on lowering voltages now trying to find the sweet spot.

 

[LtMatt]

How's this 8pack?

Beating out wazza and Nick in super pi speeds anyway.

5ghz - 2133 - 10-11-11-21-1T @ 1.6v DRAM - PLL 1.875

Looking good mate.

Grrrrrrrrrrrr nice one bud

Any chance of you trying 8gb sammys in a gigabyte UP4 to see if 2400mhz is possible?

Need to clock my new pair of sammy green, and given the huge catalogue of settings, my brain balks a bit, but have managed 2133 stable on a previous set.

 

[8 Pack]

I am overclock profiling on the UD4 next week so I will give it a go yes. I am sure its possible with tuning. Giga have matured with Bios when clocking this RAM.

 

[LtMatt]

How about a 2700k, P8P67, Sammy Green 16gb overclock profiling 8pack.

 

[8 Pack]

P67 is old chipset mate. Not sure we have one in stock for me to try on.

Nay bother i thought you might say that. Would a motherboard upgrade be advisable or will this do nicely for sandy bridge?

Matt, my fans finally arrived this morning so I *might* be getting around to putting my sammy green in later and having a go overclocking.

My mobo is the MSI Z68A-GD80 (B3), will be interesting to see how I get on.

It took a fair bit of work and tweaking Mike to get mine stable. I'm still tweaking and working on them now. You bought 8gb yeah? That should be a bit easier to get right.

The voltages you need to play with our DRAM, VCCIO, PLL. You should be able to get the same timings at me at least. I run 32mb super pi runs to test stability. If i fail or get an error i bump voltage two notches then rinse and repeat.

4 Dimm population Z77 is stronger for sure even with SB chips.

 

[~Mike~]

Matt, yes I got 8GB, why did you get 16GB?

Managed to clean out my system fit the new ram and fans.

Had a quick go with this, never OC'd ram before.

i5-2500K @ 4.8GHz

2133MHz 9-10-10-21 - 1T @ 1.55V DRAM PLL 1.8V

 

[wazza300]

looks good guys,though I never found I had to touch pll,only used one click more vccio from stock 1.05v on z68

on z77 didn't have to touch vccio

 

[8 Pack]

Each IMC is different but Wazza you are correct for me too I dont need over 1.05 on about twenty chips at 2133mhz @ 7-10-7-24 1T 74 Trfc.

 

[LtMatt]

Urgh, yeah my ram is not stable. I thought it was, but its not.

I've even tried going really high with voltage and still it doesn't pass prime 95 blend custom 4096 > 4096 using 6gb ram.

2133 - 10-11-11-21-1T
PLL 1.9
DRAM 1.65
VCCIO 1.20

I'm out of idea's now.

 

[wazza300]

What trfc are you using? Could try with 24 instead of your 21 timing

I'll try that, can't see it making a difference though.

 

[LtMatt]

I've taken 8Gb out of my system to see if that's what is causing the problems.
