Can someone help me and tell me where im going wrong, is this is correct to oc my cpu?

Amd Athlon 64 X2 3800+ (socket AM2) 2000Mhz X10Multi Bus - 200 Ht Link 800
Asrock A-liveSATA2-Glan
Corsair Value Select 1Gb X 4 DDR2 4300 266mhz. 4-4-4-12-15 1.8V
G-force 7950 Gt GS. Stock 580/750 Oc'd to 640/850
Hiper 580 Watt Sli Edition
Windows Xp Home 32 Edition (i know about the ram :P 3.3gig)

2.2ghz 220mhz X 10 - 2200mhz (2.2ghz) Stock is 2.0ghz.

Any higher than 2.2 it becomes unstable

At stock my processor is using around 1.185 Volts, it can go to a max of 1.250. I leave the voltage on Auto to use how much power it needs and i up the Core Speed by around 20, after 20 even 25 it just crashes when booting up or when i begin to "Stress" the cpu by trying to load something.

I also have Core Temp up and the cpu temps arnt even that high enough for it to crash IMO. Stressed at 2.2 it heats up to around 46oC

Thanks For The Help,
Paul.
 
I wouldn't leave the voltage on Auto, always better to set it yourself. What you need to do is rule out the ram from the equation firstly. So slap a multiplier on it so that it runs underclocked. This means you can up the FSB for the CPU without worrying about the RAM craping out on you. ;)

When you say max 1.250v for the CPU? Is this when you leave it all to Auto... that surely can't be the max option which you can select is it?

By the sounds of it, you can hit 2.2Ghz on stock volts. So now if you need to go higher, increase the voltage manually and try for 2.3Ghz, if that works, then 2.4Ghz. When it fails just bump up the voltage a bit more.

I'm not sure on max temps and max voltages for the AM2 CPU's. If it's similar to the s939 CPU's then max temp on air under load should be about 55-60ºC. Voltage about 1.5-1.6v. But not too sure if that relates to AM2 CPU's.
 
Should drive to my house and do it for me :P only 40mins away from me heheh

Im sure before ive ran is at a 9 X multiplier and it didnt boot, so i had to take out the battery :S

Right, i have now "underclocked" my cpu, i changed the multi to X 9 now and its running at 1.8 Ghz.

The Max Voltage i can select is 1.250 V i have set it at 1.200V

Im going to try and increase the FSB, So if you dont hear from me, my pc has blew up.
 
Hello again, im having trouble when i reach 255 X 9 - 2.3ghz. It wont boot, increased the voltage more and it still wouldn't boot up.

Might this be because the Bus - 200 Ht Link 800 Is set to auto and when i was at around 244 X 9 the Ht link was 890. ?? Would setting these at 200/800 make my pc boot at 255?

Hmmm... still a bit unsure as to why the max voltage is sooooo low mate. But what you are doing is correct.

1. Put a divider on memory so that it runs underclocked.
2. Use a lower multiplier on the CPU to run that underclocked.
3. Up the FSB and test.
4. From point 3 you will find your max FSB.
5. You can then try altering the multiplier and the FSB value to get a stable overclock.

But you won't be over to overclock very far at all if we can't set the CPU voltage higher than 1.250v. Is there anything else set to AUTO in the BIOS?

When you ran 9x255 = 2.3Ghz what did you increase the voltage to mate? Don't forget that the motherboard may not like very high FSB values. With regards to the HT Link speed, on s939 sytems this has to be kept under 1000Mhz (this may be the same for your AM2 setup). (So for example, I am currently running 800-ish).

If you are upping the FSB then I would set the HT link to remain at a lower value. In my BIOS I have a multiplier to choose which I have set to x3 at the minute to keep the HT Link below 1000Mhz. Do you have anything similar?

Cheers.
 
Hello, thanks for the help. I cannot find a cable for my camera to upload some pics :P. When the cpu was at 245, the Ht Link was at 890. I have no clue what it will be at 255 as it wouldnt boot up.

How do i divide my memory? As it is pretty poor memory so this might be the problem.

About the max voltage, 1.250V is my max that i can set it up to. Is this down to my psu or the motherboard its self?

Thanks for the links, ill have a read. Will it work as the guides are for single for and mines dual? Will it be the same concept?

on the guide it states "Keep in mind that HyperTransport will be the limiting factor for going above 250Mhz." mine is having trouble at 255 :P so i changed the multiplier back to 10,

If your HT was at 890Mhz when you had an FSB of 245Mhz then I'm guessing when you were up at 255Mhz the HT Link was probably around 920-ish. That's if I've worked it out correctly. :p

I'm not sure on where the option will be on the board (or even if it has one) but you want to look under the area where you can set the RAM timings, and try and find a DRAM Ratio or something similar. It'll probably be set to 1:1 and you need to try and set it to a different ratio.

For example, 11:12 ratio would mean with an FSB of 255Mhz:-

255 x 11 = 2805 / 12 = 233Mhz RAM speed.

(i.e. Slower, which is what you want if you know you can go higher but the RAM is holding you back). :)

But the guides should work regardless of dual/single core. I used my old s939 guide when I moved over to my X2 and it was exactly the same. I just clocked it like I would a single core CPU and it worked. :) At first I thought there'd be options for both cores, but it wasn't, it was exactly like clocking a single core CPU.

If you want, yes, up the multiplier and use a lower FSB value to try and achieve the overclock. It's swings and roundabouts really. High Multi and low FSB or Low Mutli and high FSB... usually the latter is better as you get more bandwith with higher FSB values.

Make sure the BIOS is up-to-date as well mate in case there are any additions or fixes added, and just try and set everything manually and not to auto. :)

Cheers.
