Salcin74 Posted December 4, 2011 Share Posted December 4, 2011 Hi everyone, I recently bought a new set of memory sticks, threw them in and thought nothing more of it until my new game Skyrim started crashing to desktop. There are a lot of people out there having trouble with CTD in this game so I thought it was the not to uncommon case of release-early-get-it-working-later that seems to plague the industry. I tried every suggested solution and waited for 2 patches but nothing seemed to help and I had no temperature issues. In a last attempt I reverted back to my old memory set ******** Platinum XTC DDR3 1333MHz 6GB KIT and low and behold the game was working just fine. I then put the Corsair modules back and started to look at the memory settings in bios which I at first install left at default since I don't overclock my cpu, that made them run at much lower speed of course but I had planned to look in to that later, the game was first priority.. =) I prefer to leave the voltage settings as low as possible and my goal with future overclocking is to go as high as possible on default voltages or at least very marginal increases. Just to get the new memory set running I tried the XMP profiles, #1 doesn't work at all and #2 increases the QPI/DRAM voltage to 1.35 which I am not really comfortable with since that turns the number red in my BIOS. I read on this forum that #1 is for Gulftown but haven't really found anything saying that #2 is recommended for Bloomflied. I still tried out XMP profile #2 and ran some memtest and prime95 64-bit for 12+ hours so it seems stable for sure but shouldn't this set be able to run at 1.2 without any trouble?

Reply With Quote No, they should run at 1.5v. If it's stable , then you should be good to go. Unless you were talking about QPI voltage, and even that is not uncommon to have to add extra memory controller voltage. #2 increases the QPI/DRAM voltage to 1.35 which I am not really comfortable with since that turns the number red in my BIOS. Don't be uncomfortable with it. It's absolutly normal. The BIOS is basically just wants to make sure you are making the right changes. It will turn red first then yellow and finally purple the higher you go. So actually red is at the low end of the scale. Kind of a stupid they used re for that . People see red and want to stop. Your rig should be set with 1.5v DRAM buss voltage and 1.35v QPI. You may be able to lower qpi voltage some if it really bothers you. Just test with memtest after every adjustment and lower until it becomes unstable. But if it is stable with XMP #2 then i would leave it go.

Thanks for the reply, makes me more comfortable. Link to comment Share on other sites More sharing options...
peanutz94 Posted December 4, 2011 Share Posted December 4, 2011 No worries. FWIW i have been running 1.65v and 1.4v QPI for almost 2 years . We have the same procesor. :) Link to comment Share on other sites More sharing options...
Salcin74 Posted December 4, 2011 Author Share Posted December 4, 2011 Good to know, it seems those chips are pretty good overclockers. As I mentioned I'm going to overclock it a bit but at the same time try to keep temps down as high temps are directly related to noise. I have put in some effort getting it quite and prefer it to stay that way as much as possible. Link to comment Share on other sites More sharing options...
Salcin74 Posted December 4, 2011 Author Share Posted December 4, 2011 Looking at the color of the QPI/DRAM setting it was in fact purple and not red so I have started decreasing this, 1.25 was no problem so I will keep testing until I get as low as possible with them still running stable.

peanutz94 Posted December 4, 2011 Share Posted December 4, 2011 With that chipset 1.25-1.45 is perfectly fine. Sorry i was wrong about the colors too. It does in fact go to purple before red. I checked my own bios to be sure. But if they are stable at 1.25v then it's all good. If not just raise QPI untill it is stable again. Color scale goes from normal , purple, yellow and then finally red when you get real high in the voltage scale. Link to comment Share on other sites More sharing options...
