Hi,

absorbed the stickies and had a bash at ocing my venice 3000 and got the following:

AMD 3000 venice oced to 2530
memory at 2-3-3-6 at 1t
on stock volts
281 x 9
htt at 4
running a 133 divider = 181mhz
rest of pc as sig

got her up to 2620 but was a bit unstable (291x9)

then stepped her back to 281x9 for stability

any tips on squezzing more out ? not too sure about upping the voltage atm, but was thinking about trying to get the memory a bit faster

thanks :)
 
the voltage is too low, stock voltage for a venice 3000 is 1.4V you could drop the HTT multiplier, run the ram on a divider and give you the room you need to overclock further, then continue pushing up the FSB which will pull your ram speads and cpu clock up.

agreed - drop the HTT to x3 and then up the voltage to 1.4V and try again. 1.4V is totally fine!!
 
I'm pretty sure 1.4V is already set but it's undervolting. When my voltage is set to 1.4v I get 1.36V according to CPU-Z.

Up it to 1.45V. Should get you to 2.7Ghz :)

got upto 2673mhz
using 1.525 in the bios (although corecentre and cpuz say 1.4v???)
couldn't run a 1meg super pi
 
i know theres no such thing as 'safe' voltage when it comes to overvolting, but what sort of voltages are people running on air / low end water cooling on a daily basis?

specifically on Venice processors really
 
ok she seems nice and steady at:2574mhz

ram on 140 divider @ 200mhz 1t 2.3.3.6
286fsb
1.4v in bios

The above seems a nice balance...


just playing my memory:
G.Skill 1GB DDR ZX PC3200

had to slacken the timings to 2.5-3-3-6 to get past 220mhz (at 225mhz atm)

will try and combine the above with any ram improvement so may have to go back to 133 divder :)


rest of spec is :

MSI K8N Platinum NF4
Athlon64 3000+ Venice (o/c'd 2.5Ghz) 34C ave
Zalman CNPS7000B-ALCU
2 x 512Mb GSkill ZX CAS 2.3.3.6 @ 1T
ATI X800 256 VIVO (o/c'd / Stock)
2-Samsung SP120 SATA2 250gb
LG 16 Dual Layer DVD+/-RW
Antec SmartPower 450w
Antec Sonata

if it's 3000+ on decent air cooling then 1.55/1.6 is perfectly acceptable.

though dropping the HT and increasing the RAM divider is very sound advice... with any luck you'll be pushing on for 2.7/2.8Ghz. I'd try for the magic 3ghz if you get a chance. though getting it stable there is a faff. :D
 
using 2.5-4-4-8 at 245mhz atm

whats the verdict in the ram ? better to run at cas 2 at 215mhz or 245mhz at cas2.5?
 
Hmm not sure on the ram tbh, but try changing the timings to 2.5-3-3-7 and see f it still passes memtest. Just run 3dmark sandra memory benchmark with ram at the two different speeds and timings, see which wins.
 
cheers fella

will do :)

put her back to 2601mhz with ram at 216mhz on a 150 divder super pi 1meg at 33seconds fastest I have had all day ! cheers :cool:
