Overclocking CPU (Athlon64 3000+ Venice) With Asus A8N-E

post #1 of 99
Thread Starter 
Hi,

I use :

AMD Athlon 64 3000+ Venice 1.8 ghz prosy
ASUS A8n-e Mobo
transcend 2x512mb ddr 400 ram
BIG geforce 6600 gfx card with 256 mb VRAM

I wanna overclock my prosy. I dono anything abt overclocking. So, please help me out.

Here Is the detailed Summary of my system(CPU, RAM, mobo, chipset, bios n GFX card) :



BTW, I checked my bios. I dono how 2 handle with OC as iam a newbie. Think there are 2 menus where the overclocking takes place, the dram submenu in the cpu menu and the jumprefree setting menu. so, Which 1 to handle with?

Things in Jumper free configuration :

OverClock Profile - (AUTO, manual, standard, A.I.O overclock, AI N.O.S) Auto is the default option. To which i should change?
OverClock option - disabled
N.O.S Option - disabled
cpu frequency - 200.0
pci express clock - 100 mhz
ddr voltage - auto
cpu multiplier - auto
cpu voltage - auto
pci clock sync mode - auto

Wat are the other info required?

Please help me how to OC in step by step manner. :cry: :cry: :cry:

I tried OCing my CPU n here is the result :

multiplier - 9x
DDR voltage, CPU voltage - auto

First changed cpu frequency to 220 - It was stable
next changed cpu frequency to 230 - It was stable
next changed cpu frequency to 234 - Not stable

Now Stable @ 225

Is this the max tat i can OC???

Wat should i do now??? something with voltage??? ram???

Thanks in advance

Check out the AMD OC Guide in my sig, it's very extensive and should answer any questions you have. Read it, work with it and come back when you hit a wall.

^^^ thanks a lot man

Now here i go:

I OC to 9x250= 2250 @ 1.500 V and my system is stable. CPU temp normally stays @ 40-44*c and on load it goes to max of 55*c, is tis normal temp?

Should i go further? As here @ my place, in summer its very hot


Please check out my settings in BIOS that are related to OCing :

Values is red are modified ones n that in braces are default values...

Are they correct???

Doubts :

Why should Hyper Transport Frequency set to 3x???
Wat r those untouched values in DRAM Configuration???

Wat should i do next????
post #4 of 99
The HT frequency is set to 3x because that times your CPU frequency equals your HT speed.... and on a socket 939 board like yours, you want to keep the HT speed at 1000 MHz or less. The untouched values in your DRAM configuration are your ram timings.... you can leave those where they're at until it's time to adjust them. And the memclock index is set at 333 to keep your ram speed down because that will increase as you increase your CPU frequency. How long are you running Orthos to test for stability? And keep an eye on your load temps while testing....I'm not sure about your CPU, but I don't think 55C is too bad for load temps on that one.... what are you running for a CPU cooler?

You could slowly increase your CPU frequency.... maybe 2-3 MHz at a time, but no more than 5 MHz.... raise it, then test for stability. If it is stable, then you can give it another little bump.... just go slowly.... OCing takes time. Good luck!

A quick note as well. You really should try to keep that Venice under 50C if possible but with added vcore and a stock cooler that may not be possible. If you don't have any $ to spend on a better cooler than I would advise that you don't add any more vcore. I don't mean to add a plug for myself but I do have a used Thermalright XP-90 that I used on my socket 754 Venice and it did a great job, that being said it is just sitting on my desk right now looking for a home. If you are interested in buying it or anything PM me.

Keep us up to date on your progess.

Nice job.... now is when an aftermarket cooler would help to bring those temps down and let you squeeze a little more out of that OC.

Navino, have you tried finding the limits of each component yet? Please check out this guide when you have a chance and try the process out: http://www.overclock.net/faqs/31782-...pu-memory.html. You may not actually need that much voltage. How high were you able to clock the processor at before you need to start adding voltage changes? What is your HT multiplier set at? Settings that you want to look for in regards to that should be 1x, 2x, 3x, 4x and 5x.
I just recently tried pushing a 3000+ Winchester but I couldn't get it passed 2.5Ghz stable. Seeming you have a Venice core you should have a some what easier time playing with it.

Good luck
