OCZ- DDR400 CB- DDR500. I get better performance from the OCZ. I have then both set at the same divered and the CB is set running a 5X HTT.<br /> <br /> I dont get this post and the info. Im tired which maybe why I dont? <br /> <br /> The best you can do is 9000MB/s to match the processor but ram dont go that fast anyway. text/html 2005-05-26T00:23:09-05:00 PCGEEK http://www.hardwareanalysis.com/content/topic/44095/?o=20#280014 hes runing default bro 1.1 . we covered that already . text/html 2005-05-26T00:16:33-05:00 Jason Jimenez http://www.hardwareanalysis.com/content/topic/44095/?o=20#280010 Yes, both the CPU and RAM are governed by the FSB (or by HyperTransport in the case of an A64), but they can have seperate multipliers, so your RAM frequency doesn't necessarily dictate your CPU's clock speed. Say I have RAM running at twice the bus frequency as my CPU...then it'd have a ratio of 2:1, so that you're not accidentally overclocking your CPU or vice-versa. text/html 2005-05-25T23:50:15-05:00 PCGEEK http://www.hardwareanalysis.com/content/topic/44095/?o=20#279998 will it let you tighten up the memory timings ? Have you tried ? text/html 2005-05-25T23:45:25-05:00 sven http://www.hardwareanalysis.com/content/topic/44095/?o=20#279993 in cpu-z it says the HTT is 200 or 210 when it runs at 2.311GHz so im assuming that the HTT shown in CPU-z is really the FSB. i think i get it <br /> <br /> But my ram is terrible: 2.5, 4, 4 @ 2T.........i dont know much but i know thats bad. Any suggestions? text/html 2005-05-25T23:27:26-05:00 PCGEEK http://www.hardwareanalysis.com/content/topic/44095/?o=20#279984 HTT default is 5x. so FSBx5x2= your HTT speeds. <br /> <br /> Do not ever under clock your HTT it needs to be 2 GHz to 2.2 GHz all the time. try to never go under that or you loose performance.<br /> <br /> Sounds like yours is on auto so 5x your fine. text/html 2005-05-25T23:14:29-05:00 sven http://www.hardwareanalysis.com/content/topic/44095/?o=20#279980 is the HTT ratio the 5x, 4x, 3x option?<br /> <br /> if so, then mine is currently at Auto x Auto x 2 = god knows what,<br /> <br /> but cpu-z says it 2.311 so thats good enough for me <img src="http://media.hardwareanalysis.com/smilies/smile4.gif" width="14" height="14" border="0" alt=";)" title=";)"> <br /> <br /> when i switch the HTT the comp will not boot and when i specify the fsb to ddr400 the comp is noticably slower (mainly in loading my album lists from wmp). Why wont it let ME overclock it??!?!?!?!!? text/html 2005-05-25T22:26:07-05:00 PCGEEK http://www.hardwareanalysis.com/content/topic/44095/?o=20#279967 to figure memory its FSB x 2 if useing default 1.1 ratio. so in your case 200x2. My board has it listed as ddr 400 in bios already to make it easy .<br /> <br /> To figure HTT for thows who dont know. HTT is directly related to bandwidth of your memory and cache. <br /> <br /> HTT ratio x FSB x 2 = HTT speed. text/html 2005-05-25T20:00:33-05:00 Mothow http://www.hardwareanalysis.com/content/topic/44095/?o=20#279902 sven<br /> If you have PC 4000 which is DDR 500 or 250 fsb.That would give you 2.750ghz = 250 x 11.Its your multi x the FSB.that will give you your GHZ. Now throw in the ram divider's and you will really get confused..lol But its simple once it clicks for you .<br /> <br /> I think this is what you were asking. text/html 2005-05-25T18:42:24-05:00 Supreet Virdi http://www.hardwareanalysis.com/content/topic/44095/?o=20#279872 11 x 200 = 2200Mhz text/html 2005-05-25T18:36:33-05:00 sven http://www.hardwareanalysis.com/content/topic/44095/#279868 yes supreet i know, but is that 200 times the multiplier (11 in my case), w/ an equivilant FSB how you get the clock speed? Im 99% sure that it is. Jus twondering if i took 266.5 actual speed of 533 effective RAM times that by the multiplier and raised the FSB that high if it would be a clock of 2.9+ on the CPU? it prolly wouldnt be supported without raing the voltage but is that the basic principle behind it.<br /> <br /> and yes buying PC1600 on accident would be unfortunate<img src="http://media.hardwareanalysis.com/smilies/smile1.gif" width="14" height="14" border="0" alt=":)" title=":)"> text/html 2005-05-25T18:20:58-05:00 Supreet Virdi http://www.hardwareanalysis.com/content/topic/44095/#279860 DDR = Double Data Rate,....
