Iv'e just built up the courage to atempt some overclocking on my AMD 3500 Venice by using the Gigabyte "easy tune" software supplied with my Gigabyte GA-K8N-SLI MB. This allows me to increase the CPU clock speed but dosn't allow me to change the RAM speed so every increase in CPU has the same effect on the RAM. The PC starts to lock up at 2.4 Clock speed, is this about right? or is the RAM causing the probs?. I assumed that I had to lower the RAM before upping the CPU any help appriciated.

When monitoring temps speedfan reads maybe core 44C but easy tune reads core 39C at the same time which is likely to be correct? What is the safe max load temp for a 3500?

Sorry about so many questions.
 
It depends on what speed the Ram is rated to and if it is a premium brand or not

If you've got to 2.4 then your fsb must be 218. That's too much to ask of value pc3200 ram.

Also is you AGP/PCI frequency locked? May also cause problems in not.

I suggest you overclock from the bios. Lock the agp/Pci freq and set the ram on a divider.
 
I'm not sure about the venice but for a winchester I would be ok with load temps below 60 degrees but preferably nearer 50.
 
Easy Tune is poo mate do it in the BIOS, i've got the same board as you and it is easy with intelligent memory thingy in the BIOS.
 
Managed to oc a 3500+ to 3246 for a screenshot and 2907MHz for 24/7 use totally stable with 1.55v, was a venice 0610 I think...what make is your value RAM as ive got some geil that is value pc3200 which can get to 250mhz cas 2.5.
 
Cheers guys. Have decided to go with the bios route. In simple terms what do I set each value at to acheive 2.4? Would i leave the multiplyer at 11 and increase the FSB to 220? Do I first lower the RAM to 166?
 
At an fsb of 220 / 11 multi / 166 divider, the ram will run at 172mhz

At an fsb of 240 / 10 multi / 166 divider, the ram will run at 200mhz

Take a look at the table in this post.

To work out what your ram speed will be :

first find what multi you're using, then find what divider you're using. Where the row / column meet is the value that you divide your cpu speed by to get your ram speed ( hope that makes sense )


Or download the app in this thread, and use it's ' calculator tab '

I'd stay away from its other options until you get used to overclocking, or they'll cause you problems / lockups.

Yeh, if you put your RAM on a 166 divider and drop the CPU multi to 10 then at first, you'll be underclocking the RAM but overclocking the CPU. This is useful because it takes the RAM out of the equation for a bit so you can see how far your chip can go without stressing the memory.

If you then up the FSB/HTT to 240, then your RAM should be running at 200MHz again with the chip @ 2.4GHz. You might need to up the vcore a little but just see how it goes & keep an eye on temps using coretemp. You should also check out the program in the link below, it's very useful for working out values :)

Thanks for the help. This is what I'm going for. FSB 240, multi x10, RAM 166, HT x4. Any body see any issues before I go.
 
Yeah go for it running at 166/240/10x is the easiest way to test 2.4GHz with ram at it's default speed.
 
OK guys. Set it at 240fsb, x10 multi, 166 RAM and x4 HT. F10 to save, PC reboots, posts saying "OVERCLOCK 240!!! if PC hangs press DEL on reboot" (or something close to that) then reboots I bottle it and press DEL and reset values to default. Is this a standard warning and what should I do?
Cheers
 
thats a standard warning on gigabyte 939 mobo's mate...I get the same on my k8nsc.
 
Should I not press DEL and will it boot into windows normaly? Will it give me that warning each time or just the first time?
 
it'll always give the warning, its just so that if your cpu is overclocked too far and it hangs on the bios screen press f1 to enter bios so if you dont press it itll just boot xp assmuming parts can deal with the overclock u use.
 
I have tried 11 x 210 =2.3 and 10 x 230 =2.3 with 166RAM and 4 x HT system boots and runs 100% OK. If I try even a small increase from there the system refuses to pass post screen (gives overclock warning then re boots then loops). I then have to set all values to default to allow system to post and load windows. Is a volt increase needed? Any ideas welcome.
 
Try the 133 memory divider and 240 HTT just in case 166 makes the board run the memory at tighter settings making it unstable as the overclock takes it back up to 200. I have my memory settings configured manually to get around such problems.
 
Latest update. I now cannot raise the FSB at all past stock (RAM 166, x10 Multi, x4 HT) Will not go past post (just loops). Any Ideas welcome.
