Ok here it goes...I am overclocking my conroe x6800 B2 using just a simple bump in the multiplier...I am up from 11 to 12, and I appear to be stable using just simple voltages (around 1.23)..is that voltage too low? I thought that the best thing was to adjust voltages to the lowest possible while still maintaining stability.<br />
<br />
I couldnt make the 13 clock ratio stable, even when I took the voltage up to 1.375. when I did that, my vcore temps went around 55C and that made me nervous. Right now, they are humming along full load under orthos, at 44C. Is there a better way to overclock? I thought about lowering the multi and raising the FSB frequency. Havent done that yet. <br />
<br />
My ram is running 4-4-4-4-12 T2 @ 2.1 volts, and that seems pretty decent.<br />
<br />
I also noticed peopel talking about ram to fsb ratio 1:1 is the best. Mine is set to 3:2. Is it best to change that, and if so, how?

Thanks for the messages guys.....but back to the questions...is it a good idea to stay at 12 and raise FSB, and should I change the fsb / ram ratio?

also, is it right to stay at minimal voltage?

You could try the vcore at "Auto" and monitor temps to make sure that it doesn't get too high. 55C is the Full Load (Prime95 on both cores) that I feel comfortable with. Idle temps take a backseat to Load temps, Load is the most important.<br />
<br />
RAM timings look good. I wouldn't mess with them for now. <img src="/images/smilies/smile.gif" border="0" alt="" title="Smile" class="inlineimg" /> <br />
<br />
Did you change the divider yourself, or is it on auto? You should find an option under Advanced Settings in the BIOS. If you are uncertain which it is, post back. Maybe take some pics of your BIOS screens and post them as well.<br />
<br />
I would set pre-determined plateaus for your OC to "sit on" for a few days or a week. During this time, play, surf and torture that system to see if it handles it stably. Prime95 should run on both cores for at least 8 hours w/o failing. Once you have decided that your system is stable, take it further.<br />
<br />
Good luck, I look forward to seeing your success. <img src="/images/smilies/thumb.gif" border="0" alt="" title="Thumb" class="inlineimg" />

hey thanks for the advice....so it is better to run the ratio of FSB / Ram 1:1? I am trying to find it in the bios, and I am sure I can if I keep looking...I can try the vcore setting at auto...right now, sitting at 1.23, I am still error free on orthos torture test. Would it even be advisable to change it to auto? so, if i set the fsb to ram 1:1, that will bring my ram around 1000 mHz, correct?

also, isnt running orthos the same as prime 95 per core, as orthos automatically deals with the affiniy issue by smashing both cores?

ok here it is...went into the bios and found were I can manually assign the ram and fsb speeds...cool....I left it laone for now, because I found options for FSB and RAM turbo mode...any idea what that is? I turned them on, as they were off previously. I tried to boot with vcore temps to auto, but no post. so I chanegd them back to ultra low and booted fine...I couldnt boot with ram at 1000 mHz either....does it make that much difference to adjust ram to 900 mHz?

Sorry I didn't get back sooner.<br />
<br />
Yeah, 1000Mhz on 800 RAM is high. You would have to boost the VDIMM up to 2.0 - 2.1<br />
<br />
Before you go any further will you post some screenshots of CPUz? This will eliminate any wording confusion...<br />
<br />
Also, Can you post some shots of your BIOS? Your rig may not have posted for another reason other than Vcore.

this is going to sound so silly..can you just take pics of the bios using print screen? never done that before...for just the heck of it, I bumped the vcore voltage to 1.3 and the multiplier to 13....I want to see if this survives orthos...ifit does, than I am in business!~

Okay,<br />
<br />
Maybe it's time to play with the multiplier. Try lowering the multi say to "10", and set the BUS speed 340. This will keep your CPU speed about the same, but bring your RAM closer to the rated speed of 400.

unfortunatly, I have not been able to find an adjustment for the FSB...it is always set at around 1000, and if you adjust it it automatically adjusts the ram...I am still finding my way around this bios...as for right now, we are still going strong with the 13 multi in orthos, temps around 52 @ load.

the only way I have been able to adjust frequency is using the AI utility.

Hmmm...<br />
<br />
Got a digi-cam? Take some shots of the various BIOS screens and post them. That will help a lot.<br />
<br />
52C is getting up there.... but okay for now.<br />
<br />
IMHO Prime95 on both cores is the way to go:<br />

again adjusted the voltage....back under 1.3 volts and running prime 95 on each core...temps around 44-46C...if this stays up all night, we are definatly in business!

<br />
Sounds good.<br />
<br />
Also, those BIOS shots will help alot. I am no where near a Guru, but do have experience w/ 4 different core types. Your BIOS shots will help sort it out, because I have discovered that the logic and methodolgy is generally universal, but the terminology can vary. <br />
<br />
I looked at your CPUz shot again... your FSB is at 1066. I believe that is the rated FSB for your MoBo. Is that the case? We have similar systems. Here is a screenshot of my CPUz and BIOS, maybe it will help:<br />
<br />
CPUz: <a href="http://img101.imageshack.us/my.php?image=3520gl0.jpg" target="_blank"><img src="http://img101.imageshack.us/img101/1877/3520gl0.th.jpg" border="0" alt="" onload="NcodeImageResizer.createOn(this);" /></a> Note the Rated FSB speed.<br />
<br />
BIOS: Note that these are a month old and @ 3.2, but for all intents and purposes are still relevant.<br />
<br />

<br />
See if any you spot any similarities and then use them as you deem appropriate.<br />
<br />
I hope that this is helpful.
