I'm looking to upgrade new memory for my pc. I was close on deciding on which one to get but noticed that one had a lower voltage. The memory that I want to replace runs at 1.5V, one of my options has the same voltage but the second option has a lower voltage 1.35V. Should I get the one with lower voltage? I'm kinda leaning to it because less power mean less heat generated which in the end comes out to better performance. option 1 http://www.newegg.com/Product/Product.aspx?Item=N82E16820231742 option 2 http://www.newegg.com/Product/Product.aspx?Item=N82E16820231734 my motherboard ASUS crosshair V Formula-z and my cpu is a AMD phenom 2 1090T
Go with the lower voltage because.. 1. More overhead to overclock as I'm sure it can handle more voltage if needed to boost the bus speed/multiplyer. 2. Lower power consumption which also means less heat generated. 3. Pretty much the same price and same timings.
Thank you for your reply I don't do any over clocking so not worried about that one really. Will the lower voltage one perform better then the one with higher voltage or about the same? Will this make my CPU run better power wise since it doesn't have to provide as much power from the memory controller? specs on mty cpu http://www.amd.com/en-us/products/processors/desktop/phenom-ii#
Im curious - why would you want to buy such slow ram, when higher speed ones are hardly more expensive?
Easy, the memory controller can only handle up to 1333. Anything higher you risk of frying your cpu. Integrated DRAM Controller with AMD Memory Optimizer Technology A high-bandwidth, low-latency integrated memory controller Supports PC2-8500 (DDR2-1066); PC2-6400 (DDR2-800), PC2-5300 (DDR2-667), PC2-4200 (DDR2-533) or PC2-3200 (DDR2-400) SDRAM unbuffered DIMMs – AM2+ Support for unregistered DIMMs up to PC2 8500(DDR2-1066MHz) and PC3 10600 (DDR3-1333MHz) – AM3 Up to 17.1GB/s memory bandwidth for DDR2 and up to 21GB/s memory bandwidth for DDR3 Benefit: Quick access to system memory for better performance.
Fair, but if you are buying 1333 MHz ram, then get some with cl7 - they will be much faster than the cl9 ones youve looked at.
Much faster on paper to be exact. Take the CL9s. If you actually could notice the difference between CL7 and CL9 then people would gather in groups to sacrifice goats to honor you.
Nah Smagjus - with lower cl, the memory access times gets lowered, which Means that the game can access the relevant data faster, which in turn Means that your minimum fps will be higher. Blueangleofdeath : Yeah, i cant seem to be able to find any of them either... all the cl7 memory were high performance modules of their time, so they usually didnt come at bigger than 4gb per block, such as this kit http://www.ebay.com/itm/G-Skill-F3-...erzubehör_Arbeitsspeicher&hash=item51bb62da1b But depending on your budget, you could just buy 2 of those kits.
The current memory I have now is CL9 and it seems ok to me. I did find that Crucial makes it in cl7 but not the right amount that I need. Currently I have 4x2gigs that is 9-9-9-25 the g.skill ones are 9-9-9-24. Thank you both for your help so far
They don't ship to US but here is the same thing. While this would work I would need two sets to get 16 for about 20 bucks more. This would kill the idea of being able to go up to 32 gig though . http://www.newegg.com/Product/Product.aspx?Item=N82E16820231402 here is some more. http://www.newegg.com/Product/Produ...06519 40000147 600006156 600006131&IsNodeId=1 I'll consider the idea though
That's a theory and only works under the following assumptions: The data is not present in cache. The dats is present in memory. The accessing time is high enough that it actually effects minimum FPS.
will more space effect my memory bandwidth with 16 gig or 32 gig? I think I'm going to stick to the 8x2 I had picked out before.
Smagjus : You are absolutely correct, but i read a lenghty test (which i obviously cant find now) that showed CL made a Whole lot bigger difference for game performance, than taking 1 step up in MHz. The test was conducted in Far cry 2, with a 3960x at 4,6 ghz, a gtx 690 and a wide range of memory. The fps was around 150 ish, where the average fps between 1333 MHz and 2133 MHz memory was 7. But the interesting thing was that the difference between cl 9 and cl 11 2133 MHz memory was about 2 fps - not huge, i know... but considering the memory was at same clockspeeds, i think it was quite signifcant, considering that almost doubling the clockspeed only provided 7 fps Blueangleofdeath : No, only memory clockspeed and amount of ram channels used will affect memory bandwidth, and your motherboard has 2 channels, each connected to 2 sockets
Sweet! Thank you for all the help guys Hmm I wonder if my graphics will end up working better then it is now. I did a memory upgrade to an old laptop a long time ago it made it super fast and that only went up to a gig I can't wait to see what 16 gigs will do with this.
I have a new question now. the page on newegg says this "This memory is rated at 1333MHz to deliver up to 10.6Gbps bandwidth per channel to deal with the evolving needs of today's operating systems and applications. Cas Latency 9 timing ensures smoother system response." AMD site is showing this for CPU Integrated DRAM Controller with AMD Memory Optimizer Technology A high-bandwidth, low-latency integrated memory controller Supports PC2-8500 (DDR2-1066); PC2-6400 (DDR2-800), PC2-5300 (DDR2-667), PC2-4200 (DDR2-533) or PC2-3200 (DDR2-400) SDRAM unbuffered DIMMs – AM2+ Support for unregistered DIMMs up to PC2 8500(DDR2-1066MHz) and PC3 10600 (DDR3-1333MHz) – AM3 Up to 17.1GB/s memory bandwidth for DDR2 and up to 21GB/s memory bandwidth for DDR3 Benefit: Quick access to system memory for better performance. The stuff from AMD says 21GB, is that per channel (2 slots)? The stuff at new egg saying 10.6 bandwidth per channel. Please confirm that I have this right. If each channel is 10.6GB you're really getting about 5GB out of each slot. If I had something in each slot it would be 5+5+5+5=20 or 10.6GB for channel A and 10.6 in channel B it comes out to 22GB total bandwidth with 8gig in each slot with 32ish gig in total storage. Also does the 10.6 part come from the 10600 name of the memory name?
Youre confusing yourself Your cpu and motherboard has 2 memory channels, which each has 2 memory sockets. They are placed like this: 1 A, 1 B, 2 A, 2 B 1 A and B shares the channel, as does 2 A and B share their channel So just place the 2 ram Blocks in socket 1 A and 2 A, and you will get the 21gb bandwidth Just a further note - placing an additional ram kit in 1 B and 2 B will not increase your bandwidth - it will just half the bandwidth to each ram block, compared to only 1 ram block per channel.
Yeah a little confusing. I get that it will work now but I'm just trying to figure out the how part. So if I put all 4 modules in all slots it would be about 5 each. Where does the 10.6 come from then? is the 21gb total bandwidth or per channel? EDIT: AH I think I got it now! 2 modules equals 20GB but with another 2 modules comes out to another 20 for a total of 40 but it gets cut to 5GB a module for it to work correctly.
