As stated in the thread title, this is my first attempt at overclocking. I'm trying to get the highest overclock possible without making any changes to ram settings on the system in my sig. I read the [H] oc'ing faq and decided to go with the easiest method with is raising the cpu fsb. I locked the pci bus frequency as recomended, disabled "cool n quiet" and changed the cpu config settings in the mobo from "auto" to "manual". Next I raised the fsb in 5mhz increments until the system locked up. I was able to achieve 220mhz X 10= 2200mhz before locking the system up. I then lowered it to 2150mhz just to be safe. I think this was an awesome overclock considering I am using value ram and not changing any other settings.

The one issue I am running into is that for some reason, I loose my oc after my system has been on for a few hours. It's like the mobo automatically drops my fsb and the clock speed drops back to 2ghz. I've hear that this is a sympton of using cool and quiet but I have it disabled. If I reboot, it will return to 2150mhz for a few hours before it repeats this action. There is no instabilty in the system when this occurs, I can continue whatever task is at hand and you wouldnt even notice it was happening if it wasnt for the cpuz readout. Has anyone heard of this? I appreciate any help or advice you can give - Aratech
 
i just did my first oc' on my 4400+ and went from 2200mhz up to 2530mhz and going up to 2600 if my stock coolin keeps my temps down. settings are: HTT @ 230, CPU multi @ 11x, LDT multi @ 4x and ram divider @ 6/5. CPU temps around 38-40 degrees

Thats awesome!! What ram are you using?
 
Thanks :) im just using kingston value ram at the moment thats why i hav the ram divider. its at 210mhz from 200mhz. i dont want it higher than that as its not meant to be oc'. Good luck on your oc'. post ur results.
 
You will need to change the RAM settings to get a decent overclock, especially when using value ram - a divider will allow you to push the FSB up for the CPU and keep the RAM at a lower speed. Hopefully you will have gotten some confidence from your current results and push ahead. Read the stickies in the AMD forum and the OC forum, they contain step-by-step instructions for most of it.
 
yea i know. when i overclock the HTT some more to say 250mhz i will lower the ram to163mhz which will calculate to around 200mhz. (i think)
 
w00t!!!

I looked in bios setting and this is what I see:

Max mem clock: 200,266,333,400,433,466,500,53 3,550,600

1T/2T memory timing: Auto,1T, 2T

CAS# latency: Auto, 2.0, 2.5, 3.0

RAS# to CAS# Delay: Auto,2,3,4,5,6,7

Min RAS: Auto,5,6,7,8,9,10,11,12,13,14, 15

Row Precharge: Auto,2,3,4,5,6

ECC enable: Disable\Enable

HyperTransport Freq: Auto, 1x, 2x,3x ,4x, 5x, Auto

I dont see anything that says divider or ratios.

Also, I was able to hit 2.4 by changing telling my mobo that I had PC2700 instead of PC3200 (see pics above). Is this the same as using dividers?

Yes, it is.
 
Aratech you've got the exact same mobo as my roomie. Its a little goofy how they arranged the settings but it definitely does have dividers. The listings that you put up for all the mem speeds are the stock speeds that the ram would run if you weren't raising the HTT. My roomie's board was able to push his 3800+ X2 to 2.6ghz. So I would definitely shoot for that unless heat starts to become an issue before then. He had to go from 1.35 vcore to 1.45 to get there. I noticed that CPU-Z pic says u're running 1.5vcore already? Any reason for that? I personally would see how far the cpu will go under stock voltage then adding a little bit at a time until you think the temp is too high. Also I'd suggest OC'ing one thing at a time like the guide says. It really does work and gets good results if you're patient with it.

I dont have a clue why its at 1.5vcore. The voltage settings are set to auto mode. I havent moved them. You mentioned that your roomie has the same mobo...can you tell me where I can find the divider settings in the bios? The only menu options I can see are the ones posted above. I was only able to oc by changing the ram speed to 333 from 400.
 
For the voltage problems, it could be that cpu-z isn't reading it properly, check what the bios says the voltage is. As for the mem dividers, the ones you listed are the right ones. Running at 240mhz HTT and your ram at the 166 div gives a 200mhz mem speed in the end. You'll probly have to drop to the next slower divider to get much over 2.4ghz. Also if the bios says its pushing 1.5vcore thru the venice check to see if you have the latest bios. My roomie had to flash his to enable proper dual core support.

I'm lost. You said the listed dividers looked fine? Where are you seeing dividers? All I did to keep the system stable was change the ram speed from 400 to 333. I highlighted it below...

Max mem clock: 200,266,333,400,433,466,500,53 3,550,600

1T/2T memory timing: Auto,1T, 2T

CAS# latency: Auto, 2.0, 2.5, 3.0

RAS# to CAS# Delay: Auto,2,3,4,5,6,7

Min RAS: Auto,5,6,7,8,9,10,11,12,13,14, 15

Row Precharge: Auto,2,3,4,5,6

ECC enable: Disable\Enable

HyperTransport Freq: Auto, 1x, 2x,3x ,4x, 5x, Auto

Thanks - Aratech
 
Right, what you highlighted, all those are memory dividers, they just aren't listed in ratios like 1/1 or 5/6. There's info in eclipse's OC guide to help you determine how to calculate how fast your ram will run given a certain multiplier and HTT speed. His guide is different from the one stickied at the top of this subforum. His is in the AMD cpu section, I used it and found it to be very helpful.

Noob! :p I was looking for something that looked like a ratio setting. I'll read eclipse's oc guide some more and report the results. Thanks - Aratech
