Running Ripjaws X 2133 @ 2245 MHz?

[captkirk]

Has anyone had their Ripjaws X CL11Q 2133 MHz running at speeds of 2245 MHz / 1.64V?
This is what i currently have my ram running at and it seems to be very stable and blazing fast. What is the ceiling on this memory and can i go even higher safely as long as my temps are still in check?

Sounds pretty good with the native CL11, offhand I don't know of a ceiling, I haven't played with this particular set alot, but they might go a bit higher at CL11, it's all in how much you want to push and are comfortable with.

Overall, this memory is very impressive. Every time i have pushed it a bit more, it has responded. Can my timings of 11-11-11-30 be lowered at all or am i stuck here because frequency is just too high....If i can tighten up just a bit, what should i try?

[Tradesman]

Could start at 2133 and try 10-11-11-30, that would prob be a better boost than even 2250 at CL11

Can you try them @ 2133 9-11-9-27 or 9-10-9-27 on 1.65v ?

[Tradesman]

Can try, I'd start with the setting I suggested and slowly work down, when tightening the timings you may have to raise DRAM and/or MC voltage and there's a chance of the CMOS resetting if it fails, which is no big deal (unless running RAID and losing the RAID setup), it all depends on the comfort level of the OCer

I ran some tests using AS-SSD benchmark but i found my results to be quite erratic seeing that this tool is primarily used for testing my SSD read and write times. is there a specific utility i can run besides memtest to give me better results for ram speeds and timings? Overall so far using AS-SSD my top score was 844 using 10-11-10-30-2t @2133MHz, but when i ran it again i got 741 score @ same settings?

Might take a look at MaxxMem2-Preview v1.98, can find it here:

May want to use IE, they had a problem w/ downloads through Firefox and Chrome awhile back, not sure if they fixed that yet

[captkirk]

Thanks for the link, downloaded it and ran some tests...here are the results.

10-11-10-30-2T@2236MHz = 25.05 Gb/sec / Memory-Latency 42.9ns
11-11-11-30-2T@2236MHz = 24.92 Gb/sec / Memory-Latency 43.6ns

10-11-10-30-2T@2133MHz = 24.33 Gb/sec / Memory-Latency 45.1ns
9-11-9-27-30-2T@2133MHz= 24.36 Gb/sec / memory-Latency 44.3ns

I am not sure but correct me if i'm wrong, the top result @ 2236MHz seems to come out on top. The bottom 2 @ 2133MHz seem about the same. Is there any more wiggle room to improve top score, or have i pretty much maxed out my options?

[Tradesman]

maybe 10-11-11-31-1T @ 2236 , may have to ease up to 1.7 or raise VCCIO up +.04

[FedericoUY]

The crowd ask for 9-10-9-27-1T @ 2133MHz @ ??? volts !!! (I need to give my mushkins 1.74v for that, and 1.15vccio...)

[Tradesman]

Can try and see what happens

We are the crowd Tradesman

I tried 9-11-9-27-2T@1.64V and it was stable but 9-10-9-27-2T crashed. I am hesitant to raise my voltage over 1.64 because anything above that shows up red/pink in my BIOS.
Gigabyte Z68X-UD3H-B3. Vtt is already at 2.1V which i believe is close to Max.

You're at a point it's got to be sort of hands on, if you can keep us informed of the progress
