kesopeso Posted June 28, 2005 Posted June 28, 2005 What are the best voltages to stick around when overclocking a64 with venice core? Around 1.6-1.7v? I have air cooling, Zalman CNPS7700Cu and currently i'm trying to get it stable with 1.475v * 110% at 250 - 260 fsb, cpu multi 10x... is that at least near to normal?

Angry_Games Posted June 28, 2005 Posted June 28, 2005 id never go over 1.65v on air, and probably never over 1.75v on water...with phase-change...who knows a Venice SHOULD do up to 2750Mhz @ 1.575v - 1.600v...too much voltage is just as bad as not enough voltage (cept not enough voltage wont kill your cpu) try 1.300v + 126% (also look in the Overclocking Database - 939 thread for what others are using for voltages) Share this post Link to post Share on other sites More sharing options...
Angry_Games Posted June 28, 2005 Posted June 28, 2005 and also try the -2 version of the bios for BH-5 Share this post Link to post Share on other sites More sharing options...
kesopeso Posted June 28, 2005 Posted June 28, 2005 hm :... isn't -3 version of bios for BH-5? Hm...ok i'll flash to -2. Should I use BIOS version 5/10 or 6/18? Is dual chan supported on dimm1 and dim3 in 5/10 bios? I've read somewhere that dimm1 and 3 are better for high voltages than dimm2 and dimm4... is that true?

Darklord Posted June 28, 2005 Posted June 28, 2005 Hey AG, But my Venice needs 1.7V to be stable at 2.7GHz. ANything below that and it is unstable. Share this post Link to post Share on other sites More sharing options...
$anka Posted June 28, 2005 Posted June 28, 2005 for the moment i'm also trying to get my venice stable to 2.7 but i'm stuck at 2.65, when i'm home from work i'm gonna try a little more voltage (i'm now at 1.56V) Share this post Link to post Share on other sites More sharing options...
suio Posted June 28, 2005 Posted June 28, 2005 My experience says too much voltage on the Venice core does not help. 1.30v plus 123% is the best. P.S. My OCZ BH-5 doesn't like higher voltage either. Share this post Link to post Share on other sites More sharing options...
kesopeso Posted June 28, 2005 Posted June 28, 2005 HM :... I can't get past 2600MHz. Are you guys using water or air cooling? What are your steppings? Share this post Link to post Share on other sites More sharing options...
Guest burningrave101 Posted June 28, 2005 Posted June 28, 2005 P.S. My OCZ BH-5 doesn't like higher voltage either. You sure you just dont need to burn your RAM in so it gets used to more voltage? Usually BH-5 style memory will use as much voltage as you can possibly give it. Share this post Link to post Share on other sites More sharing options...
suio Posted June 28, 2005 Posted June 28, 2005 It was burnt in at 3.2V for many days. I am not sure if it needs burn-in at a higher voltage range. I got errors (prime and occt etc.) for the same settings at higher voltage. Share this post Link to post Share on other sites More sharing options...
EL_ Posted June 28, 2005 Posted June 28, 2005 yeah my bh-5 hated high voltage too. hoping that time will improve the ram/burnin. I find that venice doesn't like the higher voltages so try 1.55 until you max out. Share this post Link to post Share on other sites More sharing options...
suio Posted June 28, 2005 Posted June 28, 2005 yeah my bh-5 hated high voltage too. hoping that time will improve the ram/burnin. I find that venice doesn't like the higher voltages so try 1.55 until you max out. At 1.55V, my Venice 3000+ (0519) can do 295Mhz x 9 maximum (but not remarkably stable). I am happy with 280Mhz x 9. My strategy is to maximize the CPU Mhz and use multiplier for the RAM. My OCZ Gold BH-5 can handle 230HTT at 3.1-3.2V. Share this post Link to post Share on other sites More sharing options...
