4400+ Brisbane overclocking with AMD TA690G MOBO - Page 7

Heya all. Thanks for all your replies.

@thlnk3r, on my quote, I asked about the individual max settings right. What would happen after i combine my results. Will the result for cpu, ram be below the max settings or will it be at the max settings or maybe the settings are able to go higher?? Mind correcting my knowledge on this.

Recently, I went to do the CPU max test and I found out that 2760Mhz was my max. I wonder is it because of this thats why I could not get 2.8Ghz??

@dr_bowtie, yes i believe it's possible to achievce 3GHz but it is not going to be easy for a 1st revision brissy to reach 3Ghz and it even if it were to reach 3Ghz, it would be of a high Vcore.

@The Duke, Thanks for the info bro. As many people who are using brissy, faulty thermosensor is causing a heck of a pain to all but currently, I'm using my bios as a check on my temps.


Thanks all again for your replies. Peace.

Well, on the topic, seems i could not get higher. Trying now. Will post with results for higher speeds. If not, i guess its my limit.
I don't think you're at the limit by a long shot. You should try the memory settings dr_bowtie suggested (trfc 127.5, async 8, etc) and see how they fare.

There would be two more possible causes of failure besided the memory settings: hot CPU or hot mobo. While the cpu can be easily checked (bios readings are more trust-worthy imo) the mobo is a bit more difficult.

First you can make a finger test (put the finger on the chipset radiator) - if it's warm and you can keep your finger on it, you're fine; if it's too hot to touch, then you must cool it to OC further (put a fan to blow fresh air onto the radiator). There could also be a heatbag above the VRM (black tiny 1cmx1cm chips that must be 3 or 4) don't touch them while plugged in. You should assure that there is airflow around them to cool off.

If the memory settings, chipset temp and VRM temps are fine you can say you reached the CPU limit, but I really really doubt after reading your thread.

I can do it on 1.325vcore on my 4000 Brisbane with my LLKs but the Ballistix need 1.45v to get the same...
It's true the brisbanes can OC really differently if you change the rams. My 4400+ runs now @1.4V at 3GHz with the OCZ, while with the Ballistix it needed 1.45V for the same clock. I can perfectly understand why they can't scale the phenom that is even more complex.

Heya, thanks for your post. Well, with the settings bowtie suggested, I still couldnt pass orthos. I went change each setting manually first after start combining 2 den afterwards all three still wont work. Spend a whole sunday to do that. Haha. Well, I do not know what to think now.

Drago, I believe Samy has already tried those settings with no success.

Samy, it's difficult to combine each components maximum limit. For example, even though my G.Skill's maxed out at 244mhz (frequency) I can't even come close to 210mhz when my processor is overclocked. When I tested the maximum component speed with my memory that was with my processor way below the 3000mhz mark. I always play with my memory after I've found a stable processor overclock.

I hope that helps....good luck

@thlnk3r, ahh. Thanks. So its not possible to reach the max results of individual items when combined together. O well.

Anyway, now I've up my FSB to 273. Trying to stablize it with tighten ram settings. Cause at 270 with lose settings its was ok right. When i move fsb to 273, the rams are complaining with not enough voltage. So I do not think its not enough voltage, it is the timings. So now, trying it out.

Samy, looser timings might actually help stability. I'm trying to bring up the vdimm recommendations for your OCZ memory but the site I normally look at isn't coming up

Good luck

Thanks man. Well, from the manufacturer webby, it says 2.1V is needed. Not sure about that now. Which web are u going to for your checking??

Samy, the site I was referring to is: http://ramlist.ath.cx. Give 2.1volts a try and see if that works.

Good luck

I saw that, but it seemed he tried them, but a different bus speed, anyway.

@sammy As I said, if nothing else works try to search for hot spots on the chipset or VRMs. I had my mobo capped at 322HTT before I realised that I need to improve NB cooling to go any further, it could be your case also.

Heya all, thx for reply.

@ drago, my NB is actually very cooled atm which leads me to think that my mobo C&Q is on cause on my bios, it does not show any C&Q there. My mobo is a Biostar TA690G. So what do you think of it??

@thlnk3r, I'm giving my ram 2.15V atm so I'm not sure of what is wrong with my rig atm.

@ Every1, well, I've read up on my mobo and found out on some webby like vr-zone, it says it is not a good OC Mobo and some say the memory timings are not avaible to changes like rebels heaven.
I'm sure some of the function is not shown on the mobo so wondering any1 here know something about my mobo??
