Ok so I have OCZ Reaper HPC 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) in my PC...CPU-Z is picking it up as PC2-6400, bit off heh, not sure if CPU-Z is just wrong or what but the voltage in the bios is set to 2.1v, and to 1066 Mhz. xD mobo is http://www.newegg.com/Product/Product.aspx...N82E16813131383 ram http://www.newegg.com/Product/Product.aspx...N82E16820227289 http://img404.imageshack.us/i/hmmlpa.jpg/ Thanks
K so the timings I manually set, they were 5, 7, 7, 20, 32, set to 5, 5, 5, 15, 26, dram frequency is still saying 533.3 MHz, not sure if that ones supposed to say 1066 or not, and still as PC2-6400, is that supposed to change or forever be wrong? o.0
Did that, same thing, Dram Frequency is 1066 MHz. Heres a screenie of the bios part, myns set like this http://img136.imageshack.us/i/o17.jpg/ and everest says...
you have to manually set memory speed in BIOS. DDR2-1066 isn't even an official speed and older systems wouldn't work with that speed... also note that DDR-1066 runs at 533 mhz technically(it transfers data twice per cycle though for an effective 1066 mts(mega transfers per second) also in CPUz, DO NOT LOOK AT THE SPD TAB. SPD settings are basically in place to ensure compatability with motherboards, when it comes to getting your RAM to run, that's up to you pretty much. I have DDR2-533 sticks which have spd settings for 266 5-5-5, they'll do 533- 4-4-4 though. also might I ask, why the nForce chipset AMD side? AMD chipsets are better at this point in time(nVidia has for the most part stopped development AMD side) and they're cheaper too. FYI I'd personally go for DDR2-800 4-3-3 if at all possible. it's technically underclocking your RAM, but performance will be better due to reduced latencies. TRCD of 3 and TRP of 3 are tough on the phenom memory controllers though. I'm still playing with mine. I find it's more stress on the memory controller than it's worth when I overclock the memcontroller so I either have to choose to back down on that(l3 cache speed and mem controller speed are linked though) or I have to back down on the timings so I end up optiming for slightly looser tmings(DDR2-900 4-4-4 is still better than DDR2- 1066 5-5-5 in most cases) and higher memcontroller/cache speeds this should help explain a bit for right ow, this is what I'm running.
