dogin Posted October 30, 2007 Share Posted October 30, 2007 Is this the best choice for this mobo? Going to add a E6850 CPU and OC it as high as I can Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 30, 2007 Corsair Employees Share Posted October 30, 2007 Yes if you plan on over clocking that would be the best choice! Link to comment Share on other sites More sharing options...
dogin Posted October 30, 2007 Author Share Posted October 30, 2007 Also, Going to start out with a Zalman ZALMAN CNPS 9700 NT 110mm 2 Ball Ultra Quiet CPU Cooler for CPU to start with and later move to H20. Will I have any clearance problems running 4 1gig sticks with the ram fans with the Zallman? Link to comment Share on other sites More sharing options...

Corsair Employees RAM GUY Posted October 30, 2007 Corsair Employees Share Posted October 30, 2007 You might yes I would check with Zalman about the clearance with this MB. Link to comment Share on other sites More sharing options...
dogin Posted October 30, 2007 Author Share Posted October 30, 2007 Will 4 1gig sticks work with their cooling fans on this board with stock cooler? I can find something later that will work, if it will work on the stock setup. Are there any OCing limitations with 4 sticks like their were on the AMD939 boards?

Corsair Employees RAM GUY Posted October 30, 2007 Corsair Employees Share Posted October 30, 2007 Yes with the Stock CPU Fan will be no problem. Link to comment Share on other sites More sharing options...

If you populate all four DRAM Banks, you will very likely have to drop the DRAM throughput. Very likely to ~8500 Speeds (1066Mhz or so). Overclocking the FSB <-->MCH will very likely help you recover some of the DRAM speed as well as a faster CPU. Regarding the stock cooler. You speak of overclocking and as such, I personally would remove the stock cooler and add an aftermarket cooler. Not only will this help you to keep your CPU cooler overall, it will help you with the very important temperature drop delta. This is the amount of time it takes for the CPU to drop thermal degrees. For example, when you game, there are portions of the game that are not nearly as taxing as other parts. If you get dropped into a firefight your CPU will be running harder and hotter than if you are walking down a pathway alone. Now the time it takes for the CPU to radiate the heat when the CPU is not being taxed will help it for the next taxing portion. A stock cooler will not drop very well or fast and very likely it will be pretty well as hot from one transition to the other. This is called the temperature drop delta. I would move to a good aftermarket cooler such as the Thermalright Ultra Xtreme 120 personally. Your CPU will love you for it. :D: Link to comment Share on other sites More sharing options...
dogin Posted October 31, 2007 Author Share Posted October 31, 2007 If you populate all four DRAM Banks....] Thanks! I do intend to get after market cooling for CPU when I find one that will fit the mobo (will go to H20 later on). So what you are indicating is the latency will have to be dropped (Can I still use T1 timings?) if I use 4 sticks. Then take the normal OC route of upping the FSB and CPU multi to get my speed up on the ram and CPU. Link to comment Share on other sites More sharing options...

Your overclock method will be the same as a normal overclock as you surmised though. Please let us know how it goes for you. Link to comment Share on other sites More sharing options...
dogin Posted October 31, 2007 Author Share Posted October 31, 2007 The new system I am building is Intel based. I did have the T2 problem on my current AMD system until I switch to two 1 gig sticks. Will I have the same problem with the Intel system with 4 slots populated????? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 31, 2007 Corsair Employees Share Posted October 31, 2007 Yes the same limitation applies to all systems that use un-buffered memory. Link to comment Share on other sites More sharing options...
dogin Posted November 1, 2007 Author Share Posted November 1, 2007 Thanks. Was hoping that T1 thing had been addressed by now. I understand 4 gigs may not post on Vista 64 until a fix is applied to the OS. Do I just start with 2 sticks ? Also what volts/latency should I try for the initial boot with this mobo (didn't see this ram or mobo in your test thread). I understand from other forums that booting up the first time may be a problem even with 2 sticks of this ram in this mobo using the latest bios???

Corsair Employees RAM GUY Posted November 1, 2007 Corsair Employees Share Posted November 1, 2007 That is not an issue just a limitation. Command Rate is not really a memory setting and would be dependent on the make and model of MB and PSU and the specific CPU you have installed. You might look this setting up on Techarp and get a better explanation. Link to comment Share on other sites More sharing options...
dogin Posted November 2, 2007 Author Share Posted November 2, 2007 Saw the link in your post to the ram specs. What does the reference to the EVGA 680I SLI Only! mean. Just the speed/latency results or does it not work on other MOBO's! I realize running 4 sticks, I won't get the full performance nor without the nVidia memory boost, but will it still work on the ASUS MAXIMUS FORMULA / SE LGA 775 Intel X38 ATX ???

dogin Posted November 2, 2007 Author Share Posted November 2, 2007 Additionally, I know that 4 sticks will not run at the lower latencies or clock speeds vs two sticks, but was thinking the higher performing ram would clock higher (not to its full potential) than lower rated sticks. I have seen recommendations on running 4 sticks of ram to stick with the cheaper DDR speeds because they can't reach the rated speeds. Am I correct in thinking I will get better performance than lower rated modules even if I can't get close to the max potential?) Link to comment Share on other sites More sharing options...

That means that the only MB that we tested that would run that specific module was the EVGA 680I MB. And mixing memory would never be suggested you are welcome to try it but if does not work there little that we can do about except to say "don't do that"! Sorry!

dogin Posted November 3, 2007 Author Share Posted November 3, 2007 Sorry, I was confusing. I do not plan to mix ram. My 4 sticks of TWIN2X2048-10000C5DF arrived yesterday. I did find the ram on your site compatibility list for my mobo (was not using the search correctly before and did not check the full list). Also found on my Mobo that it has a ram boost feature too. Getting ready to install everything fairly soon. The Zalman CNPS 9700 NT 110mm 2 Ball Ultra Quiet CPU Cooler does look to fit within the mobo heatsinks and clear the ram fans etc. Thank you for all the information. If I run into problems with the install, I will start another thread. Thanks again! Link to comment Share on other sites More sharing options...
