Splits Posted January 20, 2012 Share Posted January 20, 2012 Hi, I have 2x2GB Corsair Dominator modules, rated for 1600MHz, 9-9-9-24 timings at 1.8V. I can't fetch the parts number right now because I'm posting from a different computer. Since I built this desktop a couple of years ago I've been having trouble actually getting them to run at 1600MHz. I set the correct voltage and timings in the BIOS, but if I run higher than around 1066MHz my system will eventually hang. My motherboard specification says that it is able to cope with 1600MHz but I figured I'd just save myself some effort and run the memory at 1066MHz, 1.8V and lower timings instead. But, if I go any lower than 9-9-9-24, my system will eventually hang again. I had the same issue with my old processor, a Phenom II X2 550. Right now I'm thinking that the modules aren't getting the power they're meant to be getting. Is this possible? I've seen a couple of people complain about VRM problems on MSI motherboards, and speedfan reports a Vdimm of only around 1.15V. Low voltage would seem to explain why my system hangs if I try to increase memory clock speed/decrease timings. Or does anyone think it could be down to something else? Thanks! EDIT: I buggered up the topic title, eh. Link to comment Share on other sites More sharing options...
peanutz94 Posted January 20, 2012 Share Posted January 20, 2012 With your CPU you are limited to a max frequency of 1333mhz. AMD must be overclocked manually to get frequencies higher than that. I would suggest using google and look up overclocking guides for your CPU. Link to comment Share on other sites More sharing options...
Splits Posted January 20, 2012 Author Share Posted January 20, 2012 But even then, why does my computer hang when I set it to run at 1333MHz, and shouldn't I ought to be able to tighten the timings if I run at 1066MHz without it crashing? My CPU is already overclocked but I did it via changing the multiplier. I guess I could have a play and do it by increasing the FSB instead. Thanks =) Link to comment Share on other sites More sharing options...
ssd_noob Posted January 21, 2012 Share Posted January 21, 2012 Hey Splits. Seems I have the same problem as you with the same brand motherboard. I've started my own thread here and hope I can find a way to get the ram speed back to 1333. At 1066 I'm taking a 20% performance hit with the memory which does not seem to be good.
