Congo_Toey Posted February 12, 2013 Share Posted February 12, 2013 Hi Guys, I'm new to these forums, so first let me say hello. OK so here we are then. Ive just bought everything in the whole system, you should see from the specs below what I have. But just in case i'll describe the basics here. Motherboard = ASRock Extreme 11 with latest BIOS CPU = Intel i7 3930k PSU = EVGA Supernova NEW-1500 Classified RAM = 2 not equal 16G (4x4) kits of Dominator Platinum DDR3 2800 Quad Channel Memory, totalling 32G Kit 1 = CMD16GX3M4A2800C12 (12-14-14-36) Kit 2 = CMD16GX3M4A2800C11 (11-14-14-35) I was hoping but not really expecting to run all 8 sticks of the memory at DDR3 2800. But as the MB only goes upto 2400 in the BIOS I assumed that I would easliy with these 2 kits be able to achieve that maximum. However I was wrong. This is probably down to my own limited understanding of setting up the memory. I tried the XMP setting but no joy, so what I did was was to assume that both kits of memory should be able to run at 12-14-14-36 @ 2400 with setting the RAM Voltage to 1.65v. However that proved to very unstable I couldnt even get into windows. I am assuming that there is other voltage settings somewhere that I should set, but not sure which ones I should play around with. Is there anyone here that could point me in the right direction? I would very much appriciate your help. Thanks Congo_Toey Link to comment Share on other sites More sharing options...
Synthohol Posted February 12, 2013 Share Posted February 12, 2013 only single sets of ram are supported. combining ram is unpredictable and not suggested. Link to comment Share on other sites More sharing options...
peanutz94 Posted February 12, 2013 Share Posted February 12, 2013 There is no way your going to get 8 sticks ,unmatched kits at that , at anything much above 2133mhz. Your Mb may support the faster memory but your CPU still has to be up to the task of running the memory that fast. That CPU only supports a max speed of 1600mhz, so trying to get 8 sticks to run at 2200mhz and above is one hell of a load on the memory controller in your CPU. Really need to try something more conservative like 2133mhz with that set up. You might get two sticks to run stable at 2200-2400mhz because it is less load on the memory controller.Maybe 4 sticks if you use a matched kit. But with 8 sticks and two unmatched kits you need to go for something more conservative. You could try 2800mhz with liquid nitrogen for cpu cooling and enough voltage but nothing your going to get stable for any length of time. Maybe long enough to run a benchmark.....

Wow thanks for the reply, seems I should have come here and asked before I spent $1000+ on the memory LOL. What I was trying to do was to get a large ammount of fast memory that I could use for a RAM disk. Now I am trying to understand the benifits of Quad vs Dual channel, so I have a question then, is it faster to have Dual Channel 2x16G @ 2133MHz or Quad Channel 4x8G @ 1800 ?

peanutz94 Posted February 12, 2013 Share Posted February 12, 2013 Quad will be faster and for a ram disc speed really isn't important (to a point) because a RAM Disc already runs blazing fast. Capacity can be of a greater benefit at times. So even if you got them stable at 2133mhz with all 8 sticks it's not going show unless you run a benchmark and compare the numbers...but nothing your going to notice in a real word application. Even at 1866 if you have to go that low. Just to add to this a little the Platinum Line (at least the extremely high rated kits,2200 and up) are aimed more at the enthusiast and not something that you would or could use for 24/7 use . Most guys running these don't care about warranties on CPU's or The voltages required to get them to 2400 and up ...they can definitely exceed Intel's max specs. Don't get me wrong, there are exceptions to every situation. I have seen some people manage to run 2200 stable, but not with so many sticks and two unmatched kits. I would try and drop the frequency to 2133mhz with the settings of the c12 kit and see if that works. If not try 1866mhz at the same settings and the only thing i would change is the module voltage and set them to 1.5 or 1.6v if you need to. Wow thanks for the reply, seems I should have come here and asked before I spent $1000+ on the memory LOL. Yeah, that's understandable. But as Synthohol pointed out your best bet would have been a single 32gig kit. This would have been the perfect choice for what your looking to do. I'm not sure if you still have time to return them or not and then purchase this kit ..but that would be your best shot ant speeds that high. http://www.corsair.com/us/memory-by-product-family/dominator-platinum-ddr3-memory/dominator-platinum-with-corsair-link-connector-1-5v-32-gb-dual-channel-ddr3-memory-kit-cmd32gx3m4a2133c9.html.

To be honest I dont usually mind pushing the limits for benchmarking fun, and is what I have done on older systems, and for sure it would be fun to try on this one, however I normally back it right down during fpr daily running and this particular system is mostly for a cross between high end work station and a gaming platform. I would try and drop the frequency to 2133mhz with the settings of the c12 kit and see if that works. If not try 1866mhz at the same settings and the only thing i would change is the module voltage and set them to 1.5 or 1.6v if you need to. I will be quite happy if I can get these running at 2133, I cant add the cooling fans that come with the memory as the gfx card in the top PCI-E slot clashes with it. Yeah, that's understandable.

I cant really return them as I bought them when I was in the USA, but I am now back in China where I live. I shall try and get these running at 2133 with 1.5v it would be good, if not then I will either consider running these at lower speeds or getting the kit that you mentioned here. Thank you so much for you time and advice I really appriciate it. Link to comment Share on other sites More sharing options...

You can take the memory voltage up to 1.65v if you have to, but with the two unmatched kits there might be nothing that will get them stable. One being a 1.5v kit and the other being a 1.65v kit. But i wish you luck anyway. As far as a cooling fan for the memory is concerned, it is not needed with those modules. If you have one of the older Corsair fans I'm pretty sure they will not fit the New Platinum modules because of the light bars. Let us know how you make out!.
