pcloadletter Posted October 25, 2009 Share Posted October 25, 2009 Hi. I recently purchased CMX8GX3M4A1333C9 (8gb total) along with the MSI P55-GD65 board and Intel i5 750 cpu. After I put it together and installed Windows 7 64bit I experienced various BSOD's and plain system freezes. This is with BIOS settings at stock values. I visited the MSI forumboards and learnt that I should check that my ram Command Rate is set at 2T and increase my ram voltage to 1.6 from 1.5. Now my system behaved somewhat better, no more BSOD's but the system still freezes once in awhile, not so much when I use the computer but when I leave it for awhile. My question to you, is there anything else I should change or tweak in my BIOS regarding ram voltages, or other ram or CPU settings? As it is now, I won't fiddle with overclocking of the CPU until I get the system 100% stable. Here's pics of my cpu-z and bios at current settings. http://i35.tinypic.com/246264x.jpghttp://i37.tinypic.com/f1z9mf.jpg http://i33.tinypic.com/20gz5ok.jpghttp://i38.tinypic.com/2v3izhx.jpg http://i36.tinypic.com/v5eofm.jpg http://i36.tinypic.com/33d8h13.jpg Any help with bios tweaks regarding ram and cpu is greatly appreciated.

Corsair Employees RAM GUY Posted October 26, 2009 Corsair Employees Share Posted October 26, 2009 Do you have XMP Enabled? Link to comment Share on other sites More sharing options...
pcloadletter Posted October 26, 2009 Author Share Posted October 26, 2009 Not sure where to enable or disable that, I've been to my Cell menu in BIOS but there is nothing named XMP there. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 26, 2009 Corsair Employees Share Posted October 26, 2009 I would contact the MB maker and ask them if they have that setting in the BIOS and if so just load setup defaults and enable it and see if that will solve the problem.

Bitgod Posted October 27, 2009 Share Posted October 27, 2009 It should be a few lines below that "Memory-Z"...maybe. I have the GD80 (using CMX8GX3M4A1600C8), which is the model up, and that's where the line that lets me enable it is listed. Just glanced through my manual to tell you exactly where it is, and it's not even listed in the manual, so I can't say if this is a feature that's not on the GD65 or not. In my case, I have it enabled, and the DRAM voltage was originally set to Auto. I didn't have any problems looping through memtest a few times and the install went ok. I am having an issue where my timing is the correct XMP timing, but it's running at 1333 instead of 1600, but I'm not sweating that at the moment since I'll eventually start fiddling with OCing it, so I'll see where it ends up. Anywho, I ended up going in and manually setting the DRAM voltage to 1.65 just to see if that was causing the hold up. It wasn't, but I feel better knowing it's at the proper voltage. Your timings look fine and maybe you have to bump the power a little like you did. If you haven't done it already, I'd download a copy of memtest86+ 4.00, that version came out recently, burn that to disc and let it run overnight, make sure everything passes.

Bitgod Posted October 27, 2009 Share Posted October 27, 2009 Here, we go, I ended up needing to get in my BIOS anyway, so here's a screen shot of the GD80. Also cleared up the speed issue, it's running at 1600 now. Whole problem was the darn MSI Controlcenter software, it's a little too touchy, I sure don't like the idea of software that's going to make BIOS changes on the fly, without needing to hit an apply button. Sheesh. http://i67.photobucket.com/albums/h318/bitgod_photos/th_DSC00286-1.jpg Link to comment Share on other sites More sharing options...
pcloadletter Posted October 27, 2009 Author Share Posted October 27, 2009 Ahh cheers, maybe that's why I don't get XMP to show, as I bought the PC3-10666, 1333Mhz modules instead of PC3-12800, 1600MHz. Or maybe it's just not supported on GD-65. I have a post up on the MSI boards now asking that question. And yeah I didn't bother to install the MSI Controlcenter, I like to do all tweaks straight in BIOS. I will indeed get memtest and run it tonite. Thanks edit: I found out that my CMX8GX3M4A1333C9 doesn't support XMP, that's why it doesn't show in BIOS. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 27, 2009 Corsair Employees Share Posted October 27, 2009 They will not have XMP if the SPD is already set to those settings, check it with CPU under the SPD tab and see what is set in the SPD. Link to comment Share on other sites More sharing options...
