Ddr3 1333 work in 1066. Can I install a higher Mhz RAM alongside a slower one? 0.

Ddr3 1333 work in 1066 Desktops. Running DDR3 1333 MHz along side 1066 MHz. Can I use this in the other slot along with the original to reach a combined 8 1333MHz DDR3 SODIMMs will work fine in an MBP using 1066MHz DDR3. I only have 2 options in the bios. if the mobo supports up to 1066 and nothing higher then it will not work. The problem is that at POST, it shows it's running at the slower 1066 speed and it should probably show 1333mhz instead. Even if your PSB is 333 (FSB 333x4=1333) and your ram is 533 (2 x 533=1066) you can increase the PSB and drop the multiplier and still have FSB 1333 but I don't think this will change too much. I don't understand what the problem is with the RAM. 3. When you pick up RAM, make sure it has 1066 or 1333 profile. 0. Actual transfer rates may differ depending on the system's front side bus speed. If properly supported, the modules will operate in dual-channel mode, but both modules will be limited to the slower one, which is Can I use 1066MHz RAM in a slot that's only supports 1333MHz or 1600MHz RAM? I'm looking to upgrade and have to re-use my current RAM. 🙂 10600 is 1333, not 1066, so your base speeds are compatible. CraigHarrison Distinguished. Intel Xeon X5460 Asrock G41M-S3, with the correct pinouts for 1333 内存条的差别例如1600和1333,1066,800,667指的是内存条频率呀，越高越好。 800与667是ddr2的内存模块，而1600、1333、1066是ddr3的模块。ddr2与ddr3之间在设计上不一样，从外形就能看出来，所以如果内存插槽支持ddr2的话就不能插入ddr3，因为接口变了无法插入。 There's no benefit in going with faster RAM because the speed is limited by what your motherboard supports (the early 2009 iMac has a 1066 Mhz frontside bus. if you were to try to use it at a SLOWER speed like DDR3-1066 (because let's assume you have a stick of DDR3-1066 kicking around), then 1066/2=533, so JEDEC says it would behave like a DDR3-1066 CL7. Higher speeds — DDR3 provides higher memory transfer rates. 1 Ghz) GPU: Nvidia GeForce 1050 Ti Advanced 4GB Cerberus RAM: 2x4GB Corsair Vengeance DDR3 1600 Mhz My mobo specs about memory says: 4 x DIMM, Max. For example, DDR2-800 memories work at 400 MHz, DDR2-1066 and DDR3-1066 memories work at 533 MHz, DDR3-1333 memories work at 666. Try Teams for free Explore Teams. Support for non-ECC memory modules memory; cpu; Any memory that has the correct voltage and capacity and is same or faster than what is supported by the board should work in the board. ddr3-1066,ddr3-1333和ddr3-1600有什么区别？ 内存主频：内存主频和CPU主频一样，用来表示内存的速度，它代表着该内存所能达到的最高工作频率。 内存主频是以MHz（兆赫）为单位来计量的。 The higher frequency 1600 ram downclocked to 1333 and is working fine. Maybe if the logic board is handling that issue for one stick Pity, because DDR3 is the key to extreme overclocking. Now you have to concern with the other timing portions of the RAM being compatible. I think the BIOS is quite old, and have tried to get 1066 MHz or 1333 MHz DDR3 ECC SDRAM memory (240-pin). I may get in to overclocking in the future I bought a 1600MHz hyperx ram ddr3 4gb, but my mobo only supports 1333MHz( ASROCK-G41C-VS ) i installed it in the slot and when i turned on my PC the display was black. I suspect there's a timing issue involved with downcycling 1333 RAM to work at 1066 speeds. Will it auto-underclock to work correctly? MisterAndrew macrumors 68030.

Afaik, DDR3 clock cannot be higher than 1 GHz. 85V 2x1GB RAM Kit * Aeneon PC3-10666 CL8-8-8-15 AXH760UD00-13GA98X DDR3 1333MHz 1. 6Ghz = 1600Mhz) will work but still waste of Money Becouse RAM does not get top speed becouse cpu speed is The RAM would down-clock automatically to DDR3-1333 speed and it would run fine. Just make sure the RAM voltage is 1. Intel Sandybridge 2000 series desktop processors natively support DDR3-1333, but the quality of the memory controller means that it will usually run all JEDEC standard profiles up to and including DDR3-2133 without much of a fuss. This kit can work in your MB as it supports those speeds. I have another stick of RAM DDR3 1600 MHz of 4GB. If you stick 1333 and 1066 RAM in the same machine, all the RAM will work - but at the 1066 speed. You likely just need to purchase the correct speed of RAM. e. The speed of the DDR2 SDRAM determines how fast it can access data. 5v by default where as overclocking DDR3 1600 may need a dangerous amount of voltage. )/1066/800 MHz memory modules DDR2: 2 x 1. I tried loading up the fail safe defaults but that doesn't However, remember that the RAM will work at the speed of the slowest component. ) In theory the faster RAM should be able to work at the lower speeds and should be safe to install, however macs do tend to be fussy when it comes to RAM so I would recommend sticking to the RAM Although the BIOS/motherboard limits the memory to DDR3-1066 speeds (which I confirmed), the memory shipped with the system is DDR3-1333, thus confirming that the system will just throttle the memory down to DDR3-1066 speed. Then the very small gains may pa for themselves over time. 5V DDR3 DIMM sockets supporting up to 8 GB of system memory (Note 1) Dual channel memory architecture Support for DDR3 1333(O.
