Yoxxy Posted January 26, 2007 Share Posted January 26, 2007 JEDEC Standard timings set what the memory should be at. Please change the voltage/timings to what is listed on the label and try again. If you do not know how to do this please post back and let us know. Link to comment Share on other sites More sharing options...
bryanbzl Posted January 26, 2007 Author Share Posted January 26, 2007 my bios only allows 2.7 or 2.8v no 2.75 also... in my bios my ram is set to the stock 3-4-4-8 timings.. when i do long CMOS resets it switches some other settings in the timing options below and i changed them to auto setting... should i redo CMOS and try it out with those settings? im sure i already had it at 500mhz at a point.. i just dont know what went wrong.

Yoxxy Posted January 26, 2007 Share Posted January 26, 2007 I would set the voltage to 2.8v and also change the timings to what it says on the label. Your memory divider should also be cpu/4 (your cpu speed is 2.0/4 = 500 mhz) If you have any questions on how to accomplish this please post back. Thank you.

bryanbzl Posted January 26, 2007 Author Share Posted January 26, 2007 yes i know how everything works... im running my 3000+ at 2.7ghz right now and even when it was at the stock 1.8ghz it wouldnt read it... im gonna do a CMOS reboot and then just change the timings to 3-4-4-8 and leave all the other ones to what it puts it too itself.. im running 318fsb/8.5xcpu multi/ 4x hht link and 1.5v. im gonna try what reboot and playing around with some settings for sometime and see if it can post as pc4000 and then the adventure will truely begin ;): Link to comment Share on other sites More sharing options...

bryanbzl Posted January 26, 2007 Author Share Posted January 26, 2007 i just got these settings when i redid the CMOS. they are most likely the cause of my problem. Trrd - 7 Twr - 2 Twtr - 2 Trwt - 2 Tref - 3 my timing are already set at 3-4-4-8 (other timings that is) what should those be set too? i cant find the proper settings anywhere.

Corsair Employee RAM GUY Posted January 26, 2007 Corsair Employee Share Posted January 26, 2007 What are the exact setting you have set for both CPU and memory? Link to comment Share on other sites More sharing options...
bryanbzl Posted January 26, 2007 Author Share Posted January 26, 2007 i currently have everything running on default (or DFI's optimal default) settings. ill give you some pictures of CPU-Z and A64 tweaker. i know a64 tweaker looks really odd right now because its on all the auto settings. what should i put the settings to?A64t.bmpcpu-z.bmp Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted January 26, 2007 Corsair Employee Share Posted January 26, 2007 I am asking what you have set in the MB Bios? But I would load setup defaults and set the timing to the following since you are not over clocking. CPU Freq. 200 MHz Memory Frequency: 100% Dim Voltage to 2.7 Volts Resulting Frequency: 200 MHz Memory Timings: Manual/User Define SDRAM CAS Latency: 3T SDRAM RAS to CAS Delay (tRCD): 3T SDRAM Row Precharge (tRP): 3T SDRAM Active to Precharge Delay (tRAS): 8T Then test the system with http://www.memtest.org Link to comment Share on other sites More sharing options...
bryanbzl Posted January 30, 2007 Author Share Posted January 30, 2007 yes i am overclocking... im attempting to get it to 250mhz because thats what its rated for and i should be able to get to that point. can you help me out with the other settings in the BIOS? i have a DFI LP UT ultra-d board and there are many memory timings that i dont quite fully understand and the defaults arent helping that much... can 3-3-3-8 actually work better than 3-4-4-8. i thought that the looser the timings the more it can handle higher clocks speeds.

Corsair Employee RAM GUY Posted January 31, 2007 Corsair Employee Share Posted January 31, 2007 I really doubt that this MB and CPU will hit that frequency most likely it will top out between 220-230 Mhz from what I have seen, but if your CPU is locked getting much over 200 Mhz is doubtful.
