I couldn't even get 2133 11-11-11-28-1T at 1.5 or 1.55.

 

Try changing the command rate to 2T, it barely affects performance. Now I'm running 2133 9-10-10-21-2T @ 1.55. I was stable for about 15 mins Prime95 Blend at 1.475, but to get complete stability I needed 1.55.


CPU-Z and MaxxMem both say it's running at 1T but it's actually 2T.

The regular maxxmem results are paltry for me. I get a max of 19GB throughput out of these. I managed to find a the maxxmem multi preview and got this score...



Timings



Bare in mind I'm running quad channel.

Quad channel. :o

Nice, can you link me to MaxxMem Multi Preview? The download links on their main site have been down for months.

Here's my updated scores in MaxxMem and AIDA64. You might be able to get your tRAS and tRFC down. I have mine at 18 and 90. I haven't stability tested yet, but it passed wPrime 1024.

Unfortunately I don't have a copy of AIDA to test with : (

Managed to get this Super Pi32m Stable at 2520mhz now. smile.gif

post #1727 of 2062
Finally got it stable at 2133MHz. I running 4 x 4GB with a Gene-Z.
Timings: 10-12-10-28-1T @ 1.5V, secondary and tertiary timings all on AUTO.

Trying to decide whether to lower timings or go for lower voltage?


Not stable after further testing. No matter what I try 1866MHz is the limit with 4 sticks. I can get 2133MHz and 2200MHz with 2 sticks. I have tried on GeneZ and UD5H with 2600k and 3770k. I guess I got some dud sticks. biggrin.gif

Try changing the command rate to 2T and lowering the other timings. I have mine stable for 28 hours at 2133, 9-10-10-21-2T @ 1.4755 (I changed it to 1.5120 just to make sure I don't encounter any memory induced instabilities while messing with the PLL and CPU voltage.)

Interesting. I shall get 3 sets of these for my EX58-UD5 biggrin.gif
I don't like the look of it without a heatspreader though even though they are pointless mad.gif I like the Kingston HyperX for that very reason, when i install it it still looks balling in a Xigmatek 382
But they are low profile enough not be seen anyway even with a thinner HSF biggrin.gif (I have a Deepcool Ice Blade GS coming to me)
G.Skill sticks on the other hand looks awful IMO

I just picked up a set of these and am I right in thinking the 1228 after the tko means they were made on the 12 month 28th day? and does this really matter when over clocking them? also would like some general starting points to get this ram to run at at least 1866 with my sig. thanks

Only bought them to use my new cooler..lmao..biggrin.gif
