    Corsair Vengeance Pro 2400MHZ unstable with FX9590

    Hello!

    I have the Crosshair V Formula Z motherboard with a FX9590 and I had purchased myself a pair of Corsair Vengeance Pro 2400MHZ 2x8GB thinking I was clever so there’s no surprise that after putting these sticks in, I’m greeted with BSOD on start up.

    I presumed that I had faulty sticks and RMA’d them and for a little while I thought that had did the trick until I realised that they are running on 1336MHZ. So, going into the BIOS, I changed the memory frequency to 2400MHZ and I’m greeted with the BSOD again.

    After searching around, I’ve seen people disable ECC and change other bits and bobs which I’ve tried to replicate but I’m just having no success whatsoever. So, I thought I’d come to the professionals for some help!

    I really hope that you guys can help me out with this so the patches of hair that I’ve ripped from my head can regrow, lol.
    I’ve attached screenshots of the last settings I tried that before reverting back to 1336 so I’m able to use my computer for the time being.

    Thanks in advance!

    Just for those who wondered, I'm still in need of help with this.

    Unless your specific memory kit is on the QVL for your board you may have to manually tune the settings and you still may not reach the advertised speed. Treat it like an overclock (technically DDR3 2400 is) which means increasing incrementally rather than trying to go directly to 2400. See if you can get it stable at 1600, then step up again. It's tedious but really the only way if a particular memory kit isn't happy out of the box.

    Hey!

    Thanks for replying, I'll definitely give that a go. Would I need to change the timings for the lower speeds? On the memory modules they say "11-13-13-31". Am I okay to set those timings for 1600Mhz?

    I'm not that overly confident in overclocking. I know how to change the timings, the memory frequency and DRAM voltage going to them. Is that all I need to focus on?

    Thanks for your help and sorry if I'm asking silly questions!

    TBH, I'm not comfortable with all of the timings and sub-timings involved in fine tuning either. I generally adjust to get "good enough" and don't sweat the small stuff as I'm not trying to break records.

    So generally you should keep in mind that as you increase the frequency you may need to loosen the timings (increasing the numbers) and/or increase the voltage. If you loosen/tighten timings you can increase them together so you aren't there all day but I would adjust the frequency separately. Google for some good timing values to try.

    I would start with the advertised timings and increase the frequency by steps until it becomes unstable. You can't really hurt anything doing this. At that point you can loosen the timings if you want or increase the voltage. Probably start with increasing the voltage a bit. You should google around to find out what voltage other people use long term on your platform. The voltage can do damage.

    Ultimately you may need to increase voltages for the memory controller. Be careful not to go too high as that could be game over.

    I ran the DDR 2400 Corsair Vengeance ram @ 2666mhz and 11/14/14/32 2T. However I am on an Intel z97 Maximus Hero VII board. (4790K as my chip). Not sure if that really helps but it was the largest overclock I had, maybe your system would like the overclock? Not sure. Try 1.68v at first, then up to 1.72v. Mines stable at 1.7v. 4.8ghz core and 4.5 core overclock on chip.
