I have done a search for this board on this forum and not a single hit for it. Was wondering if anyone has had any experience overclocking this thing? So far I have found a review/test that is similar to my setup but what steps do I take to achieve such results as:<br />
<a href="http://www.anandtech.com/mb/showdoc.aspx?i=2819&p=4" target="_blank">http://www.anandtech.com/mb/showdoc.aspx?i=2819&p=4</a><br />
Also, I see tons of boards where you can change the HTT multiplier but this board does not have such an option. The only settings it has are 'Standard' and 'For Overclocking' and the manual or internet has no explanation as to what it does. So far I have done the following and it seems stable:<br />
CPU multi: stock 12x lowered to 10x<br />
FSB: stock 200MHz increased to 245MHz<br />
DDR2 Voltage: stock 1.90 increased to 2.00<br />
DDR2 Freq: has gone from 800MHz to 980MHz<br />
DDR2 Mem Timings: 5-5-5-12 T2<br />
Rebooting with my FSB at 255 or lower will cause a normal reboot. Setting it to 260 or higher will cause a quick full power off before POSTing. Any ideas why? Anything higher than 245 FSB is unstable. Looking for ways to push it further. Also, there are no 'dividers' on this board unless it is talking about my selectable memory frequencies. 800 is stock, has down to 400. Mainly looking to achieve the best FSB to DRAM ratio possible and maybe overclock CPU from 2.4 to 2.6 or 2.8 if it will let me. Have been able to get a 3dMark06 score from <5000 at stock settings to about ~6100 with modified settings above. This is with ALL 3d settings maxed out! Looking to get it higher. Thanks for any help.<br />

The MSI K9A Platinum is only a few days out! ( in germany )<br>
But I saw a review with an X2 3800+ on it and they clocked them up to 340HT but with lower multi! What is your HT-Multi?<br>
Set it to 3x<br>
Set a ower diverder for the Ram! 2.0v might be OK!<br>
Raise the chipset voltage .1 and push it further if you need! have a look to the temps!<br><br>
Hope this help!

You may find the memory controler multiplyer displayed as 1000, 800, 600 where as 1000=5x, 800=4x and 600=3x but that is speculation as some BIOS reflect it in that way.

I am wondering if the 'divider' is named something else. Is it the same as the memory frequency? I am listing all of the options that I consider 'overclocking' options and hopefully someone can point me in the right direction or help me decipher the BIOS settings.<br>
Here are the BIOS settings listed below, their available settings and what I currently have my settings set to. I am slightly oc'ing now and it is stable. Sorry for the long list.<br>
A note about the 'High Performance Mode,' if everything is set to default and HPM is set to Optimized (no other settings changed) then the system is really unstable. Wierd. Anyway, the list:<br><br>

</div>yes, it will be the memory frequency.<br />
On K8s it doesn't actually set an absolute speed but as you increase the "CPU FSB Frequency" the memory speed will increase too.<br />
The memory speed on AM2 CPU's is quite complicated as it has some funny dividers & varies with CPU multi as well.<br />
try <a href="http://cablemodem.fibertel.com.ar/kimero/am2tools083.rar" target="_blank">this utility</a> for working it out.

What would be better? A higher FSB frequency with a higher FSB<img src="/images/smilies/biggrin.gif" border="0" alt="" title="Big Grin" class="inlineimg" />RAM ratio or a lower FSB freq with a lower ratio?<br />
In my testing I have gotten my FSB to 295, CPU multi x9 (2.4 @ 2.655), with ddr2-800 running about 780 (400mhz base freq). The FSB<img src="/images/smilies/biggrin.gif" border="0" alt="" title="Big Grin" class="inlineimg" />RAM ratio was CPU/6 or CPU/7 cant remember since i changed it back. I am currently running 245 FSB with x10 CPU multi (2.4 @ 2.450) and ddr2-800 running at 980 (800mhz base freq) both run stable on prime95 for 2+ hours with good voltage settings.<br />
thanks,<br />

no i have one of these boards but with the amd x2 5000+<br>
same gfx card<br>
but geil ddr2 ultra pc6400 800 mhz<br><br>
i was on socket a for so long and now i have lost my touch and seem to struggle to get my head round this for overclocking but i no a man that can and im off to pay him a visit with beer in hand to watch his magic hopefully as soon as i have some more new ill let ya no matey

The tighest timings with the lowest or no divider is best.<br>
With each system give it a go and test for memory dependant progs to see whats works best for your hardware and the timings combination.<br>
See if you can determind what ICs that RAM uses. Also, have you done the low CPU multiplyer high CPU bus to see how high the RAM can run stable? You might have more headroom in the RAM to reduce the divider.

I am having trouble OC'ing this board?! Every time I try it locks up and won't reboot, even on mild oc's. I have oc'd before, so am not a novice, but I thought this was supposed to be an easy board to oc?<br />
<br />
- Do you need to turn off cool and quiet?<br />
- do you use the Core center or do it manually? (I tried both, same result)<br />
- boot sequence optical drive/ HDD. does this have a bearing? (no floppy, disabled)<br />
<br />
I have noticed it doesn't seem to like the Sound blaster SC. I have disabled the on board sound. But it was playing up prior to,<br />
<br />
I have plenty of cooling, etc. Attached is my system specs.<br />
<br />
I would appreciate your input folks, thanks.<br />

I'm having trouble overclocking mine as well. Just the slightest raise on the FSB & boom.......need to reset CMOS.

</div>Yeah mate, exactly my problem. I have a feeling we may have to turn off the cool'n'quiet before ocÃ*ng? But this is just rediculous, I can't raise mine 5 hz without it freezing! <br />
<br />
We shall see? <br />

I played with the Core Center and got my cpu up to 2999Mhz fine. Played CS:S for like 10 minutes, then put the clock back to default(wasn't sure of temp since the temp on core center doesn't seem to go over 50C) I know this is a bad way to overclock but it did it for the 10 minutes fine, haven't overclocked it other than that due to the stock 5600 cooler.

Cool, Ill check it out, thanks<img alt="" class="inlineimg" src="/images/smilies/thumb.gif" style="border:0px solid;" title="Thumb"><br><br>
We should be able to get a bit more out of this CPU tho. The 5600 X2 is not the best ocer, but it should get 3000, without a problem. I would think 50+ deg. is a little high. You might like to have a look at you cooling? I have bought a new case for my rig (see my specs). It has 3 case fans built in- 1 at front and rear and another built onto the side with the funnel to the cpu, so it extracts hot air from the cpu fan straight out of the case. I think the 1950pro has it`s own power connector? which means they will be drawing a bit of power, therefore creating a bit of heat!<br><br>
It should be no problem to fit an extra fan in there if you don`t already have 2. If your case has a vent on the side, it wouldn't be a bad idea to fix another fan to that as well on the inside so that it extracts hot air from the case straight out the side. There is a really easy mod for that. Buy a cheap, quiet, little fan. Get a hole saw, and drill the appropriate sized hole for the fan.<br>
make sure it`s just big enough for the fan only and not the housing, because you want to screw the housing to the case. Cheap but affective. Or you could just buy a new case!<br><br>
Either way LX, I think you might need more case cooling.<br><br>
Onwards and upwards, mate<img alt="" class="inlineimg" src="/images/smilies/gunner2.gif" style="border:0px solid;" title="Gunner2"><br><br>

Disable Cool N Quiet when OCing. Also, make sure there are no options Enabled that have the word "Spectrum" in it. <br />
You will likely need to set your RAM on a divider. That is to set the RAM form DDR2 800 or 200MHz to a lower setting. Perhaps 166MHz or DDR2 667 or even lower if needed.
