The figure for accurate measurement of data transfer requests then shifted from MHz to MT/s to adjust for this change, despite the fact that memory still operated at the same frequency. Instead of only actuating once on the rise of each clock cycle, it could now also process an additional operation on the fall of that same clock cycle, effectively doubling the rate at which the DIMM could process data. The problem is when DDR (or double data rate) RAM came on the scene, it changed how data transfers were registered.

Or see if you can return it because the Crucial memory selector was wrong.“Like the ticking of a clock, each tick represents a single hertz or cycle (the opening and closing of a transistor gate in this case).Ī speed of 1Hz, for example, is one cycle per second 2Hz is two per second a MHz is 1,000,000 cycles per second you get the picture. If that's no good, check the RAM you removed and if that is 1.5v then you really need a Corsair CM3X8GSDKIT1066 which meets all the requirements and put this one down to experience. Instead of only actuating once on the rise of each clock cycle, it could now also process an. OEM machines are generally more picky over things like that deviating from what they use. A speed of 1Hz, for example, is one cycle per second 2Hz is two per second a MHz is 1,000,000 cycles per second you get the picture.

What voltage is the RAM that you removed? I have looked through all the data sheets and manuals available by Lenovo but it does not state if the RAM has to be 1.5v or if it can be 1.35v. Have you tried booting with only one stick connected?

It is my understanding that faster memory can work at slower speeds but maybe the slowest speed of the one you have bought is 12800 which is too fast. Note: Only 64-bit operating systems support more than 3GB of system memory (RAM). Essentially Im comparing the following two kits: Corsair Dominator DDR2-1066 (TWIN2X4096-8500C5DF) 2x2GB - Latency5 Corsair HX2 DHX DDR2-800 2x2GB Latency4 The DDR2 1066 stuff is. Frequency CAS Latency RAS To CAS RAS Precharge tRAS tRC Voltage. I dont really understand how latency and frequency work. You may likewise to same checking with tools mentioned like CPU z and speccy aside from the task manager to confirm. 2400Mhz Cas 17 and overclock it to 3000Mhz Winner, Always speed over cas latency wins. So Im deciding on RAM for a x38/C2Q setup. the One has a lower Cas latency and the other runs at a higher frequency. Discussion in General Hardware started by HardwareCaps, May 28, 2018. 125MHz has been replaced by PC133, which is backward-compatible. The use of 1066 MHz SO DIMM memory is recommended for this system.ĢGB, 4GB Intel Turbo Memory (selected models) I would like to know which dim would be better for my build. 125MHz memory is SDRAM designed for use in systems with a 125MHz front-side bus. (that is, great density and speed/frequency), you really are set. So is CPU performance and graphics performance - not to mention bus speeds of the motherboard.

My friends PC has same speed RAM but has timings 9-9-9-24 which is faster in speed. PC3-8500 Non-Parity (NP) Double Data Rate Three (DDR3) Technology My PC has 8GB of RAM 1600MHz and has timings 11-11-11-28.
