Remember that if your RAM isn't rated to 1600Mhz and you want run it to that speed is on your own risk since that can kill the CPU's memory controller or the RAM too. Your are right, AMD support 1066MHz and 1333MHz but with OC you can run the RAM to a frequency above the stock 1066MHz or 1333MHz. The HT link don't give you any performance above 2000MHz, that's the reason for the 2000MHz manually in the BIOS eve if the mobo support frequencies above the 2000MHz. As your CPU is lock multiplier you only can OC the CPU using the FSB and not the CPU multiplier. If you are trying to OC your CPU, you need 1st disable C1E, Cool'n'Quite and AMD Turbo Mode. The mobo can easy set the 6GHz, 7GHz or more without problems. Check my rig configuration, believe me the mobo isn't your "problem", you are limited with the CPU, voltage and heat of it. My RAM is Rated at 1333 and the MB supports 1886 Overclocked but refer to the AMD Phenom ii spec, it supports DDR3 of PC3 8500 (1066 MHZ) and PC3 10600(1333 MHz) so if i put a RAM rated as 1600 MHZ, the MB supports it but the CPU doesn't so would it increase or decrease the performance ? Hello saint, thx for replying to me i just wanna classify some things i have the gigabyte ga-890fxa-ud5 and the new brand AMD Phenom ii 圆 1055T it's clocked at 2.8 GHz and 3.2 Turbo mode, by raising the multiplier and the CPU's bus speed i OC the CPU to a higher frequency, the Motherboard i guess it's designed to take a limited speed so would it be reasonable to OC the HT to 2600 or 2800, it's said that the motherboard support HT of 5200 MT/s in the manual. Hi ilysaml and welcome to Tom's forum.ġ- The recommended speed for the HT is 2000MHz something above that decrease the performance.Ģ- Of course that u can OC the CPU's bus speed but keep in mind that is u do that the RAM speed, NB speed and HT speed is linked with that bus speed in that point u need play with all multipliers and voltages for get a stable OC.ģ- If u RAM is rated u can run it at that speed without problems, but if isn't u can try it on ur own risk since AMD says that u can kill the CPU's memory controller. You are not coming close to filing the volume of that pipe. For each 10% you increase the IMC/NB above stock 2000MHz, bandwidth is increased 3-4% and latency is reduced 3-4%.Įven with a 50% OC on the IMC/NB to 3000MHz (which those wacky hardcore enthusiasts are now doing) the *snickers* you hear are from the HT link. A pipe that will carry a great deal of volume There is no advantage in a 'higher-clocked' HT link. Some motherboards can push the memory faster than others, but memory can run below its advertised speed, so it will always work somehow.Īs long as the speed of the HT link is equal to or greater than the speed of the memory. The memory connects directly to the onboard controller on a Phenom II CPU, so the HT link speed doesn't even matter to the memory. The hyper transport link goes between your CPU and northbridge - it is more a function of your motherboard, or at least that is the component which advertises it.
