Yep, 13x is topped off. Highest is 12.5 and yeah.. it's a 1700+ TBred. I'm trying 11.5x190 @ 1.70 Volts. Seems to be running stable right now. Gotta stress test... lesse what happens.

Edit: Doh!! Crashed after a while 🙁 Quite frustrated.. 1.65 @ 2.1 and i can't hit 2.2 no matter how high i go (1.85 highest). Any ideas what to do now? Tried 11.5x191 @ 1.70... crashed. 11.5x190 seemed to be stable... odd 😀 Tried 11.5X195... no good either. Sigh!
 
Maybe you did hit the limit yur CPU can go,but it also seems like something is holding you back,maybe not though.Can you set memory timings on that board?.Put it on 2.5/3/3/7 and default multiplier 11.See how that works,cause maybe your memory speed are running too tight and crashing.Most everyone always runs 2.5/3/3/7 at first to see what the limit of the CPU is.

Well, I'm running 200x10.5, so that's the fastest FSB and it's stable 2/3/3/7 for days. I'm trying 11.5x190, crashes Perhaps i have hit the limit, although kinda peeved that it's 100% stable at 2.1 @ 1.65 but i can't get to 2.2 no matter the voltage.

I'm running 1:1 so my ram is at a full 200mhz. I know it's running alright at that speeds since i can do 10.5x200 all day and all night running Prime 95, and 3dMark 2k1 looping. Also, i've run 8 hours worth of Memtest 36 and so i know it runs fine 🙂 I'll try different memories and highest Multipliers and see what happens.
 
Hey, The_Lurker, make sure you set your memory timings manually in the bios. When overclocking, never set the memory speed to "By SPD" (Serial Presence Detect). When you are finding the limits of your CPU set the CPU FSB/DRAM ratio to a value that runs the ram at a slow speed, such as 133MHz and leave the default timings. This way, you will find the limit of your cpu and not the limit of your cpu/ram. You are almost guaranteed to surpass 2100MHz if you are stable at only 1.65V.

Thx for the advice, guess i'll pump the multi and then up the bus slowly, see where it gets me. Guess i'll try a 12.5 Multiplier and start off at like 166mhz FSB and keep on going up 😀
