Sabertooth X58 Bios mod
#81
I made a filter on their website which is compatible with X58, I just want to ask you guys opinion which would be the right choice for my PC?

1600mhz cas-9 is the high end for the X58 chipset.  you do not need any faster. 

I suggest staying with your current memory kit.  just install it in 2xdual channel and configure timings/speed manually.  That 'compatibliity' statement just means the XMP profile was not setup for x58.  the ram is still "compatible", just not optimized for the x58.

X58 kits are usually cheap on ebay, easy to spot too because it's always 3x2GB or 3x4GB. You don't have to get X58 memory, but it may be better solution, we may be able to get stable if you'll let me help you adjust the settings I've been talking about all along.

@pir8man - Cas 9 is low end for X58 Big Grin I have plenty of Cas 6 and Cas7 or 8 kits for X58. As for speed, most generally was 1600-1866 back then for top end, but there is some 2000-2133 kits too but those need special skills (Tinkering, tweaking etc) to run stable usually Smile

From those you linked, I would try to find one of these (I check each link on G.Skill site, and QVL shows compatible with Asus X58 for these, and in general any kit 3x is designed for X58)
F3-12800CL9T-12GBRL Same
F3-12800CL8T-12GBRM (Second choice)
F3-12800CL9T-12GBSR Same
F3-12800CL7T-12GBSR (Best kit)

yes, there is faster, but testing showed that gains were minimal above 1333 cas-9. and 1600 cas-9 is considered better than optimal for this chipset.
you can get faster, the system will only show synthetic performance gains.

I had ddr-2000 on this board at one time, but I ran it at 1600mhz with tightest possible timings.  I did have it up to 1833 at one time, but this required too much voltage to the MCU, so I backed down to 1600 and optimized the timings.  It ran superb until I rebuilt/retasked my R3E system.


If you are looking to invest, upgrade your CPU to W3690. These are selling on ebay for about $75 currently. This will upgrade your MCU from stock 1066 dram support to stock 1333 dram support. It also allows for 1.5x uncore multiplier, instead of the 2x that your 950 requires. Lower uncore multiplier usually means less voltage & heat, so you can run those high end ram modules. This is the xeon equivalent to 980x. That would get you way more performance than any memory swap you do.

Synthetic benchmarks show good gains at higher speeds yes (Same for lower CAS, tWCL), not so much in real world is visible, that is true for the most part, but it does help in games and with graphics in general too.

CAS 9 is still considered low end, CAS6 or CAS7 blows CAS9 away in any benchmark at same speeds. Just look at your own comment, I had 2000Mhz CAS whatever, but I ran it at lower speed for the ideal tighter timings (Better/Lower CAS) 2000Mhz CAS 8/9/10 will loose out any day to 1600 CAS6 or CAS7, CAS 6-8 was the standard when X58 launched with CAS6 being the top tier modules and CAS8 being the now standard CAS9/10 because they don't make any high end IC's for low CAS anymore due to DDR3 production phasing down.

None of this applies to his issue though, and yes I agree, I'd rather purchase a better CPU than more memory and more memory is really not needed here either, only to optimize the timings manually for X58 instead of the X79 they were designed for @ tRFC, tFAW, tRRD)

I was not trying to get him into better timings, or more speed etc, only trying to get him stable. I only replied to your comments about dual vs triple channel, or CAS vs CAS, speeds etc in regards to our general discussion about that, nothing to do with his system or stability.
