But 89W consumes even more power after OCed than 65W

hurmm... i think 3600+ brisbane becomes more popular nowadays. maybe it juz about oc potential. lets hope am2+ and am3 got the same ways as 3600+

The point is that is it won't be much cooler, in fact its often slightly hotter because it blocks the chips from direct airflow. The only ramsink I know that does reduce ram temp is thermalright's HR-07.

But yeah, it adds bling..    And it protects the chips from physical damage. 
Btw, how did you measure your ram temp?

how do the foxconn mobos fare for oc-ing am2? specifically this model - N570SM2AA-8EKRS2H

If the thermal interface material in between the RAM chipsets and heat spreader is efficient then it will help to transfer heat out off the chipsets.

If the TIM is of low grade type (especially those low grade thermal tape) then I agree with you that it might not transfer heat out from chipset efficiently, hence might bring up temp instead b'cos the heat spreaders itself will limit the air flows, this will be more obvious if cooler is not use for cooling the spreaders.
faren
To me, thermal transfer efficiency of thermal tape is far below than thermal paste/grease.

I can't measure the actual RAM chipset surface temp because they've been covered up by the spreaders. My fan coolers will bring down the spreaders surface temp to ~33C. Give an allowance of 3C to 5C for the chipsets temp higher than the spreaders my DDR2 still running much lower temp compare to the bare DDR module without proper cooling. My DDR2 running well at 2.25V, the spreaders surface temp, as I mentioned just barely warm!

Guys,
Any idea for me to use 667MHz ram divider and achieve 3GHz?
If using 667Mhz, my com will not boot above roughly at 2.6 - 2.7GHz.
Currently using 533 ram divider w 4-4-4-12.

Already tested a lot of solutions and would like to hear u guys' opinions.
Thanks in advance

what is your voltage of the brisbane cpu and the ddr2 ram?

I just bought  brisbane 3600+. I am also in quest for increasing my cpu clock. Currently 1.38v for the cpu at 2470MHz (260 x 9.5). RAM still at 1.95v, 533MHz ram divider with 5-5-5-15-1T.

I am wondering if the cpu volt at 1.38v is safe for 24/7 usage? Quite afraid that I might shorten the cpu lifespan?

I can boot if using 667MHz divider, but the ram will heat quickly and after about 30 - 60 minutes later, the computer will crash and reboot even I increase ram volt to 2.1v. I didn't dare to increase higher because this kingston ram have neither passive cooling nor active cooling yet.

I think, you can try use any active cooling such as AllnGap's ram cooler if you want to try the 667MHz divider so that it won't be so hot during long operation hours. Hope this idea helps.

But everest shows wrong ram divider information. CPU-Z shows the correct ram divider that I am currently using.

I understand your situation , because it is where I've stucked as well. My problem more or less same with you, pc reboot or bluescreened at 2.7Ghz-2.8Ghz if i use 667 divider. I've look at your spec, your are using a Nforce4 chipset mobo. I'm using Tforce 6100 AM2. I suspect this is a bug of Nforce4 chipset...... I've seen people use 667divider and push to 1000Mhz without problem by using biostar TA690G, some 590 SLI chipset mobo , some 550 mobo .... but yet havent see anyone do that with nforce 4 series mobo

You are right. That is the situation i face. Tried many ram timing, pump vcore pump vdimm wont help any. Sigh
So, you also using 533 divider now?
-pWs-

IMHO, i think that your vcore is abit high for brisbane to reach 2.4Mhz. What's the stepping of your proc? Mind to share? For me i can push to 300X9.5 with stock vcore without any problem and it is not the limit yet

maybe you can try cpu multiplier X8 and ram divider 533. In that case, the ram frequency is equal to CPU/6 which means same as ram divider 667. I've tried it just now, failed at 2.95Ghz for unknown reason again 

I'm using 800 divider for daily usage. See screen shot below

yes..its kinda high for 2.4Ghz..i used only stock vcore and managed to hit 2.8GHz..the difficult part is from 2.9GHz to 3.0GHz,  becoz for me the raise of the vcore is quite high for each megahertz..

Do not wan to try x8 multi ar... Need to raise a lot of HTT to reach 2.9 or 3.0GHz.
I think i will stick to my current setting. Just wonder is there anyway to solve o not actually.
-pWs-

hmm...ic. So what's your best result so far? I meant the highest CPU frequency that you ever achieved.

by using my previous TForce 570U, the highest fsb achieved was 321.1MHz with multiplier x9..but i failed the SuperPI 32M 

that time i didnt try hard, i gave up because i need to play a lot with ram timing so i switched to x9.5 multiplier, and i stopped after i achieved 3.0GHz 

hmm...ic. So what's your best result so far? I meant the highest CPU frequency that you ever achieved.

haha, i just did it because i'm so curious. Supposed my mobo can hit around 390 HTT but dunno why today keep failing at 370x 8   

btw, what's your best shot? I meant the highest CPU frequency that you ever achieved
