Nevets Posted January 8, 2007 Share Posted January 8, 2007 System Specs: AMD FX X2 4200+ EPoX MF570SLI/G Rev 2.1 (BIOS 7JUL06) Corsair TWIN2X 2048-6400 XMS2-6400 (5-5-5-12) XFX GeForce 7900GS (Not OC as of yet) Cooler Master 500W iGreen Power Supply (SLI Certified) Artic Freezer 64 Pro (Dropped my temps 20C, now at 30 idle and 50 under full load) For the past two weeks I have been trying to get a stable overclock. Between changing the multipliers and tweaking voltages, I have been able to get stable at the following: 10 X 275 for 2750 9 X 295 for 2655 8 X 305 for 2440 On the 8 and 9 I can go higher but I have to increase Vcore to 1.58 instead of Vcore 1.54 at 10X. All other voltages are stock at 10X. Vdimm is 1.9V, HT = 3X, timings are as above. DDR2=400Mhz. According to CPUz, this gives me 275FSB, CPU/10, 5-5-5-12-23 @1T, with a bus speed of 275 and HT of 825. I guess this equates to 1:1@1T. See here: http://i4.photobucket.com/albums/y119/slessard/12121.jpg I have not touched the ram as of yet except to set the 1T and changed the 18t to 12t in the BIOS because 12t is what the ram is rated as. I think it is time to play with the ram but everytime I try to change the DDR2 setting over 400, my system will not boot so I am kind of stuck here. Could someone please advise me on how to proceed next as this is my first OC with a dual core. Question that I have: Do I need to set my memory to 2T instead of 1T? How am I to increase my DDR2 up from 400MHZ without crashing my system? What other advice can you offer me to get the best of of this system? Is 1:1 @1T good/bad/ugly or what? I read that 1T was not good for dual cores, is this correct? Shoud I loosen or tighten my timings? Thank you Link to comment Share on other sites More sharing options...
