TAKE NOTES ALONG THE WAY WITH PEN & PAPER DON'T FORGET TO WATCH THE CPU TEMPS ALL THE TIME. NEVER LET IT GET ABOVE 55°C IN MY OPINION ON AIRCOOLING, OR 42°C USING WATERCOOLING.   Finding the Highest CPU speed Mhz 1. Go into Bios, Softmenu II/III option... 2. Change Multiplier from AUTO to 10.5 (10.5x133=1400) 3. Reboot 4. Back to Bios. 5. Increase multiplier one notch (10.5 to 11) 6. Reboot & go into windows 7. Run a Sandra CPU Burn-in & 3DMark 2k1 to check stability 8. If either of above gives a blue screen or crashes, go back to bios and increase Cpu vCore voltage one notch. 9. If the settings don't produce a blue screen or a crash, back to bios, increase multiplier one notch. go back to #6  Round and round you go, until you get to the chips max Mhz... Remember that figure. You could stop here and have a nicely overclocked chip on multiplier alone, but that makes you a wuss ;) Now you have the max Mhz, you need to do some maths. We want to achieve the same speed that you topped out on above, but using a higher FSB and a lower multiplier. Finding the Highest FSB speed 1. Into BIOS. Divide your top speed so far by 166. Round to nearest single decimal place, and set your multiplier to that. Set your FSB to 166. 2. Reboot, into windows, benchmark / test 3. Any problems, blue screens or crashes, back to bios, increase Ram voltage, try again. 4. If no problems, then back to bios, and take that highest speed and divide it by 176. Set multiplier to the answer, and set FSB to 176. Back to #2 5. Keep going!! Take the Max CPU Speed, divide by 180, back to #2 6. Divide by 196 7. Divide by 200  Now, you'll get to a point where that FSB just won't go any higher.... remember that number. SO, you should now have written down on a piece of paper... 1: Highest CPU Speed so far. 2: Highest FSB Speed so far. 3: vCore & vMem voltages required to get those figures.   Next step, set FSB back to 133 and multiplier back to auto. Set the vMem voltage as high as it can go, then go to Advanced Chipset Features > DRam Settings. In here, the aim is the lower the better. First change every "from SPD" to Manual / 133 depending what options are available. This will allow you to tweak the other settings.  The ultimate aim is high memory bandwidth. From the top down are the best settings you can generally have: Dram Clock: 133 (KT266a) 166 (KT333) Timing: Manual Cycle Length (Cas): 2 Bank Interleave: 4 Way (n/a on nForce2 boards) Precharge>Active (Trp): 2 Active>Precharge (Tras): 5 (KTxxx) 2 (nF2) Active to CMD: 2 DRAM Burst: 4 (n/a on nForce2 boards) DRAM Queue: 2 (n/a on nForce2 boards) DRAM Command Rate: 1T (n/a on nForce2 boards) Write Recovery: 2T (n/a on nForce2 boards) The above settings are more or less the best settings any AMD board has to offer at the moment, and provide maximum performance, BUT your ram is highly unlikely to be able to achieve these speeds at anything above your memory's stock speeds unless its good stuff. Here's where the choices come flooding in from Samsung to Geil to OCZ to Winbond to Kingmax to Corsair... everyone wants the best stick of ram to achieve the above settings at high fsbs such as 200+. So you now need to spend a lot of time getting your settings as close to these as possible at as high an FSB as possible. Start off setting the following: (from top down) 2-4-3-6-3-4-4-2-2 9 (6-3-3-2 on nForce2 boards) Reboot, run a Sisoft Sandra memory bench. If any problems, increase memory voltage. The further down that list you got, the better your memory bandwidth became. So, you should now have an idea of what your ram can achieve at non-clocked speeds. So, first things first: You need to merge EVERYTHING together, and get your system set to your highest FSB / multiplier combo, all the voltages set, and set MEMORY voltage to its MAX. Just for a laugh, try the highest settings for memory bandwidth that you could get at non-clocked speeds. It'll probably no-post, so clear CMOS. Now do you see why I told you to take notes?? Let's continue ->  |
