Hi friends,

I have bought AMD X4 635 processor with:

Corsair XMS3 (1600 mhz) 4 GB Ram
Corsair CX400 - SMPS
Bijli Cabinet (Zebtronics)
LG DVD RW
1 TB Seagate.

Now I am waiting to get a good Overclocking MOBO for the above processor. I had liked Gigabyte 880GA-UD3H as it was also supporting the AM3+ processors.

But today I found that Gigabyte site has removed the TAG showing AM3+ compatibility with this mobo. So confused.....

Pls also give me the link for a good guide for Overclocking X4 635 processor.

Pls help me.
 
You dont have the motherboard so you havn't even booten into the system. Come bak once the system is up and running.

Till then, for initial preparations, get 2 fans on your Zebby Cabby(if it doesn't have alreadY).
 
^^ yep, but the athlon's operating voltages are different

If you want to cross 3.2GHz, you can do it at stock 1.4v(or 1.35v i think the newer cpus have 1.35v vcore stock)..

You should be able to hit around 3.5-3.6GHz with 1.45v
 
Now, I have finally got the mobo. It is Gigabyte 785 GMT-US3H.

I bought it as I could'nt find the UD3H mobo and MSI and Asus was not liked by me. Rest of the configuration is same as above.

Now would again request you to tell how to OC the PC.

Currently I am installing 64 bit OS (Win XP & Win7) in my PC.
 
the second link seems like a scam.i registered,and,in my mail,it says somethings gonna happen to my pc tomorrow,so i gotta read his mail to me again tomorrow?
 
I have OC the PC upto 3.17 ghz. The temp. and other settings taken by Everest Trial edition are given below. Pls tell if the temperatures are within limits & everything is OK.







 
wait, thats still at stock voltage right??

Well, congrats, now your CPU is unofficially a Phenom II X4 840(rebranded Athlon II X4 at 3.2Ghz)

Thanks but can u pls tell if the voltage (which has been downgraded) and the temp. are correct.
 
i think you can go higher for that voltage.i did 3.2 for just 1.3v.stress test gives a maximum temperature of 54 degrees,aim to keep it below 55(optimally).are you on stock cooling or got a aftermarket one?.and,try to improve airflow in your cabinet,it should lower temperatures too.
 
Yesterday I increased the FSB to 240 and it took the Ram to 1599 mhz which is the limit for the Ram. Is there any way I can reduce the ram further to boost my processor further?

and Yes, I am on stock cooler. Pls tell me which is the best software for monitoring OC & Temp?
 
The temp. of CPU are around 54C but of the mobo it is around 59'C. When I increase the multiplyer, it also increases the Ram whose limit in my mobo is 1600 mhz and that is why i lowered the multiplyer.

Pls have a look at these:

The results of OCing are shown below. But i am amazed to find that the different temp. monitoring software are showing different temp. Pls tell which one needs to be believed and how to use AMD overdrive ?







 
what i meant was to bring the cpu multiplier back to 14.5.so,at 229x14.5,youre at 3.333ghz,and keep the ram multiplier at 6.66.so at 229x6.66,ram runs at 1525mhz.raise the fsb higher,and youll reach the fsb wall for amd cpus before you run beyond the rated speed of your rams(1600),and i think you should be able to push the rams over the rated speed by a bit too.
 
Thanks for the help. I did 3.45 ghz by taking up the FSB to 238. I lowered the multiplier in NB and SB. But I am really amazed as different harware monitoring softwares are showing different temps.

Pls tell if these temp. are correct and which one to believe.















 
Trust CoreTemp, i've used it. And the temps are normal. Whats your ambient temperature??

Athlon IIs are very very cool running processors(explains the tiny low-profile fan)
 
If you look closely, they are actually all reporting the same temperatures.

Temp1 is the motherboard chipset temperature which will be constant at 42 or so. There's the CPU Core temperature which is also constant throughout at 43C or so.

Now AMD has this quirk where there are two more temperature readouts Temp2 and Temp3. There's some controversy to what these are... Everest is labeling Temp2 as "CPU" which is probably debatable. The temperature you should concentrate on is probably the "CPU Core". For AMD, all the cores will read out the same temperature.
