daNutz Posted June 2, 2006 Posted June 2, 2006 Hi all, Ive had a DFI SLI-DR since it was released and at the time i bought 4x512 sticks of OCZ EL DDR PC-4800 Platinum because it was listed on the DFI site as recomended. well ever since getting the memory ive never been able to get it to run at its full speed 600Mhz. ive always had to run it @ 400 with tight timings of 2-2-2-5 T2. Well today ive decided ive paid for this stuff so i wanna getting it working properly. Ive tried using mem test with the memory @ 600Mhz and it fails on test 6 with timings of 2.5-6-6-15. Ive tried just testing 1 stick and 2 sticks but they always fail. it comes to make me think its the motherboard as i cant see all 4 sticks being faulty. Could someone maybe try and help me out.? :confused: Share this post Link to post Share on other sites More sharing options...
Guest GripS Posted June 2, 2006 Posted June 2, 2006 What are the recommended timings for 600? I imagine it's going to be CL of 3 and you have it set to 2.5. Raise the CL to 3. Share this post Link to post Share on other sites More sharing options...
daNutz Posted June 2, 2006 Posted June 2, 2006 There website says CL 2.5-4-4-10, cpuz says 2.5-6-6-16. Ive tried running both but neither worked. OCZ 4800 Share this post Link to post Share on other sites More sharing options...
Guest caffeinejunkie Posted June 3, 2006 Posted June 3, 2006 Whoa man it's rare to see 2x1gb kits reaching ddr600 but 4x512 will probabaly never reach that you'll need to drop to atleast 3-4-4-8 to even get close to that so start from there Share this post Link to post Share on other sites More sharing options...
CompGeek Posted June 3, 2006 Posted June 3, 2006 You probably are running 1T, I dont think you'll manage 1T with 4 sticks at rated speeds. Share this post Link to post Share on other sites More sharing options...
daNutz Posted June 3, 2006 Posted June 3, 2006 Nope im runing T2. The PC wont post with T1. Why cant i get 2 sticks or even 1 stick to run at the timings that the manufacturer says it will run at..? Share this post Link to post Share on other sites More sharing options...
Guest caffeinejunkie Posted June 3, 2006 Posted June 3, 2006 idk maybe a bad memory controller? if not probabaly time to rma but have you checked each sticks individual spd timing table? maybe they arent all matched because i know they'll let your rma if they all arent matched Share this post Link to post Share on other sites More sharing options...
red930 Posted June 3, 2006 Posted June 3, 2006 Fist just to make sure, when you say 2.5-4-4-10 you have it entered in as 2.5-4-10-4 correct? And I would guess its one of the other memory settings holding you back, could be something simple. Take an A64 screenshot so we can see all your timings, I'm sure some of these guys are really good with that stuff. By the way, what voltages have you tried?

daNutz Posted June 3, 2006 Posted June 3, 2006 Its not a memory controler prob as ive had about 10 cpus in this board in its time and its always been the same. Yes the timings were inputted corectly. i even set everything else to auto incase something was causing a problem but still no luck Wots an A64 screenshot? please not i can only get into windows when the mem is @ 400Mhz. but im able to use timings 2-2-2-5 @ 2.85V Share this post Link to post Share on other sites More sharing options...
daNutz Posted June 3, 2006 Posted June 3, 2006 Ok heres an A64 screenie with just 2 sticks running. I will post another with all 4. Share this post Link to post Share on other sites More sharing options...
red930 Posted June 3, 2006 Posted June 3, 2006 Don't worry about all 4, you're never going to get all of them running at DDR600, they're rated for a pair of sticks only. The memory controller on the cpu can't handle it. If thats what you're aiming for I'd advise just find the best you can and stay with it.

daNutz Posted June 3, 2006 Posted June 3, 2006 I was wrong, that screenie is with all 4 sticks in. The simple fact is i cant get 1 or a pair of sticks running @ 600Mhz which they should be able to. Share this post Link to post Share on other sites More sharing options...
