No dont use the same settings as Rossi, he is on X79 your on Ivy Z77???. What board you using ?? with Ivy 2400 is easy although it depends on the motherboard.

I would say definitely try, in fact because you're on Ivy, you have a better IMC so should try for the golden 2400MHz. Don't go working on what voltage and settings i've used for 2000MHz though, you have a different CPU and probably a different batch of RAM as well so the results will vary.

I tried 2133Mhz 10-11-11-28 1T @ 1.55v and got errors in pass 2 on memtest :mad:

Slacken the timings or up the volts?

I'd try 2T before slackening timings etc

my Samsung was FAR easier to get 2T stable than 1T

and it Might be the mobo ... I couldn't get >1833 stable on 1T - errors in memtest86 etc, so gave up and went back to 2200 2T. But new bios update came out for my Motherboard last week (Gene V) - and one of the patch notes was increased 1T stability, and sure enough - now 2200 10-11-11-1T is stable @ 1.57V (thats for 16gb too)

Oh dear! Doesn't like that much. PC now won't boot. Not even to BIOS. How do I get into the bios to change back the settings?!

What VTT/VCCIO Voltages have you got set?

The IMC will need more voltage as well as the DRAM. Around 1.15v (when on air no more than 1.2v apparently on Ivy) is recommended when you start to overclock RAM.

8 Pack - I have an Asus P8Z77 V MB with an 17 3770K.

If you have any advice I'd much appreciate it. I tried Rossi's suggestion of 11,11,11,24,1T @ 1.55v but don't think it worked. After rebooting the PC stayed hanging for about 30 seconds, had to hit the reset button a couple of times to reboot. I can only assume this was down to instability?

So I changed back to the original suggestion made to me for 1866MHz of 9-9-10-28 [email protected], but made the mistake of entering 9-9-10-24 2 @1.65v. Ran memtest and it passed.

I have no idea what the difference between my mistake and intention was other than it worked!

Advice appreciated - Really think I should do some hardcore reading on this subject as going in blind could be a bit dumb.....

I will stick this RAM into an ASUS board again tonight with Ivy and give you some settings.
 
good morning gents, im just looking for two things 1) a little reassurance and 2) some advice.

i have my green running @2133 @10-10-10-28-1 @1.62v my vtt is 1.1v and my other timings are

twr - 16
trfc - 148
trrd - 7
twtr - 9
trtp - 9
tfaw - 24
tcwl - 7

im just on my 4th pass of memtest with no errors, i am very happy to stay at these speeds im not really looking for anything more out of my ram but i would like to know if i could do any trimming? volts or timing?

any input would gratefully recieved. many thanks.

buzz

**EDIT**

just passed 7 hours all is good

ok f that, anything above 2133MHz is a nightmare, i think im doing something really wrong or i have reached the max oc of my ram/IMC?
iv dropped my volts to 1.6v although the stacks are cold to the touch at 1.62v.
tomorrow i will play with my timing to see if i can drop them but i have a stable oc @ 2133MHz 10-10-10-28-1

**GOALS FOR TOMORROW**

try for 10-10-10-25-1 @2133
try for 9-10-10-25-1 @2133

any advice would be gratefully received :)

Should be doable, got mine at 9-10-10-21 1T @ 1.56v
 
RE: Thirds

Currently running 9,10,10,21,114 1T @ 2133MHz @ 1.62v
Here are my auto Third set of timings, any ideas where i should start to improve them?

Any ideas?? who you asking??

Here you go tight seconds and thirds for that IC on X79 at DDR2400 so at 2133 it should be very achievable. For 2133 you could aim for TRfc 88.



For all who are interested this is the order of importance of each timing for performance. So you should tune in this order.



These timings are Elpida IC Timings on Z77 ASUS Formula at -50C and what I currently use for Pi32mb, 2600mhz+. Who was it said cooling RAM makes no difference??? ;)
