astrometric Posted August 23, 2013 Share Posted August 23, 2013 Hello, I am building a new system with the Sabertooth z87 board, I'm trying to find the fastest compatible memory Corsair provides. I really like Corsair memory, however I don't think the memory finder tool is completely updated. For instance it doesn't even suggest Vengeance Pro kits at all, and aren't they made for this chip set? I would really like to run 32GB of 2400mhz if anyone knows of a compatible kit that would be awesome. I do a lot of video rendering, and compiling of 3D levels, and compiling large programs. 32GB would be extremely helpful. Also I've noticed that ASUS says this board supports upto 1866. This is confusing because I've seen people post some benchmarks from this board where they were running 2400 mhz memory. I know a little bit about memory, but not enough I guess. Are the higher speeds achievable through tweaking bios? and the 1866mhz that is in the board specs just a guideline or a default? Thank you for any help it is much appreciated. -astrometric Link to comment Share on other sites More sharing options...

You could use either the Dominator Platinums ,Vengeance Pro or Vengeance series modules. However 2400MHZ is a huge memory overclock and not very many CPU's have a memory controller strong enough to overclock that high. Great CPU cooling is a must as well Also I've noticed that ASUS says this board supports upto 1866. This is confusing because I've seen people post some benchmarks from this board where they were running 2400 mhz memory. The MB will "officially" support up to 1866mhz. And you CPU officially is rated only for 1600mhz. The others using this 2400mhz are doing so through overclocking ort voltage and BIOS tweaks as you mentioned. . As i stated before not all CPU's will be able to overclock that high. You caould have 25 of the exact same CPU's in a room and only a couple of them would have a memory controller strong enough to overclock that high. It is a total roll of the dice. Most of the new CPU's will run up to 2133mhz pretty easily. Above that it is hit or miss. You would not notice any difference in real world performance above 2133mhz anyway without a benchmark. And even then it's just a number. Link to comment Share on other sites More sharing options...
WesternDreaming Posted August 23, 2013 Share Posted August 23, 2013 wow, that mobo only supports 1866... and dual 8 pcie lanes well imo, dont pay any money for 1866 when its the same as 1600 tbh if you could run 2133, that would be a difference, if you could get yer ram north of 2666 that would be a difference, just get some uber low latency 1600 ram and beb done with it, the extra latency from 1866 over 1600 wont be worth it thats my imo Link to comment Share on other sites More sharing options...
dieu Posted September 1, 2013 Share Posted September 1, 2013 Purchased a 16 GB kit CMD16GX3M4A1866C9 System will not boot. No video, red on-board memory light on the Sabertooth Z87 turns on and runs through a never ending series of reboots. Remove all three and the system will boot with only one memory module installed in DIMM_A2. Also, this memory is actually DDR 1333 as it is shown in the BIOS Not sure if the Sabertooth Z87 is junk or the memory is causing the problems. Updated to the latest BIOS (1405) and now, the USB ports are no longer functioning. Nonetheless, the memory never worked, even before the BIOS update.

peanutz94 Posted September 1, 2013 Share Posted September 1, 2013 Also, this memory is actually DDR 1333 as it is shown in the BIOS No, it's 1866mhz memory. All memory will default to it's slowest speed when first installed until other wise changed in the BIOS. Either by enabling XMP in your BIOS or changing the timings and SPD manually. Remove all three and the system will boot with only one memory module installed in DIMM_A2. System will not boot. No video, red on-board memory light on the Sabertooth Z87 turns on and runs through a never ending series of reboots. Does it matter which stick? If they all produce the same results then i suspect a bad board. Since yu can get the board to run with one stick installed it might be a good idea to go ahead and test the memory with memtest to see if you cant rule out a faulty module. Again if they all test out fine then i suspect a bad board. You might even think about removing your CPU cooler to check the socket for bent pins.Or even un-even pressure on your CPU cooler can also cause these types of issues. Before removing your cooler to check the socket , i would try one last thing...that would be to remove all your memory and then clear the CMOS. Insert just one stick in the first slot and see if it will POST. If the board is good there should be no reason why it shouldn't boot with the first slot occupied. You might even swap sticks around to confirm that that slot is dead if it wont fire up. If it does, then you can shut down to add the remaining sticks. Get into your BIOS and enable the XMP profile for 1866mhz. Link to comment Share on other sites More sharing options...
dieu Posted September 1, 2013 Share Posted September 1, 2013 Excellent advice, thank you! I tried all sorts of combinations. The most memory I was able to get to boot was 8GB (2 4GB sticks). Trying to add a third in any combination or slot would result in a loss of video and the "red-light" memory check cycle. In other words, the system failed to boot. Referencing the Asus Z87 manual, it does list this memory as compatible. However, it's for version 4.xx not 5.29. Also, if I ran one 4GB stick, I could run it at XMP (1866). Two sticks would only run at 1333. Actually, the memory problem has become a moot issue now because USB functionality is completely gone. I believe it's a defective board. Once I receive the replacement, I'll report back. Thank you again. No, it's 1866mhz memory. All memory will default to it's slowest speed when first installed until other wise changed in the BIOS.
