My RAM is 1600MHz but I can't get it past 1333MHz without crashing and the XMP is no help either.

I messed around with timings but don't know what I'm doing, however, i did get windows to boot at 1333 MHz with the 10 multiplier and going from 777 20 to 888 24.

when i run the ram at its spec speed of 1600 MHz and 1.65 volts, my pc will not boot up. i have an XMP profile from Nvidia for the X58 board but it always crashes before the windows screen shows up. that xmp profile has timings of 999 and 30 or so if i remember right. anywho, that xmp specifically for my board/chipset does not work.

i read someone got their 1600 stable to 1800 with what they said was changing the CAS 9 to CAS 11. i have no idea what this is.

can anyone suggest timings and other tips for me to try to get it to 1600?

my hardware
intel x58OG extreme mobo
i7 920 stock speed 2.67-2.93 with turbo
corsair 750 bronze PSU
gtx 660 2gig
W7 64bit.

i have recently found quite a few new tools, and a tuning utilities app along with a recent bios update for this old board (that find was quite a shock to me since this board has been discontinued for so long) and i'm really excited about getting more out of my rig.

if i can get it to 1600 and start up windows, i will run memtest to check for problems. i am just unable to get windows to boot up when trying to use the factory speed.

when it comes to these kinds of things i am very ignorant, so if any of you all have any advice, no matter how small or seemingly insignificant to you, please pass it along.

More about ram 1600mhz past 1333mhz crashing xmp
  1. Is the motherboard not compatible with the ram because the ram is over 1.5 volts. I do not know how to adjust the volts. I am quite ignorant also.
  2. Set speed at 1600mhz
    Increase timing to 11-11-11-11
    Test if stable.
    Then reduce timing 1 by 1 untill it crashes
  3. thanks, i will try the 11-11-11, what should i use for the fourth number? stock timing for 1066MHz was 7-7-7-20

    and to answer schau314, i have confirmed the mobo is compatible. it can use memory way past 1600 and i also downloaded, from intel mind you, an XMP specifically for my mobo/memory but it fails.
  4. Sorry like i said. I am not that versed in ram and latency. I tried a little though since many people send ram back for that incompatibility reason.

    Make sure you have the latest BIOS, then go into BIOS with DRAM in proper slots, enable XMP select profile 1, next look in voltages and find the QPI/VTT, raise it + 0.065 from current setting and give it a try
  6. to Tradesman1- DRAM in proper slot, what does that actually mean? i have yet to install any hardware myself, i am new to gaming PC's and have very little knowledge.

    schau, no need to apologize as it was a good question. i am in the same boat with you when it comes to this stuff :) if you have any other suggestions, keep them coming ok!
  7. Your manual will give the suggested placement for 1-2-3-4 etc sticks as to which slots are preferable
  8. ah ok, going to look into that as well. thanks everyone, gonna do some testing and will report back.
  9. Will be around a bit this evening yet, and in and out over the weekend
  10. got windows to boot with RAM at the factory speed of 1600, only problem is i have 2 different apps telling me i have different mem speeds, one is saying 1599MHz and the other is saying 2188MHz or something. how can i get a true or accurate reading? what program is accurate for this?
  11. Check CPU-Z in the memory tab, it should show true freq which should be right about 800 (this is DDR (DOUBLE data rate) so with true freq of 800, double it to get effective of 1600 (+/-)
  12. thanks Trade, i indeed have freq of 800 on CPU-Z. should i run memtest now? i haven't had any bsods or errors or anything yet.
  13. Could do that or might just run Wins Memory Diagnostics, or just use it for awhile and see if any problems
