3.4Ghz @ 1.35v stable? the best 3.4Ghz i can do with my vcore is min 1.4v benchable and able to pass orthos for 30 mins. But not stable enough for daily usage, will need at least 1.45v to pass 7 hours orthos.


Its hard to say, you will need to roughly estimate by touching your heatsink. My previous brisbane Hovers around 12-15c idle on xigmatek S1283, these sort of temps are impossible given the ambient is around 28-30c. So yeah... the DTS on the brisbane are pretty much useless.


+1 vote for me for xigmatek S1283
Its the best Air cooling below RM200 that ive ever bought in the past few years. Which is also the cooler that got me out of thermalright fanboyism

to me, a perfectlly stable system that meets my 24/7 requirement isnt only orthos, well.. othos is part of it, but it has to pass at least 8 hours followed by a 12 hours of memtest... yea its quite some hassle, but it worth the while =)

nice result, im sure theres alot more headroom in that tracer of yours

i totally agree with you, any Asus board which is below RM500 are pure garbage. Not to say they suck, but the only good boards they carry are mostly the high end board. Their value boards are one of the worst.

1) Is my initial setting correct for the HT link, The RAM frequency as well as for the multiplier?
- Well, there isnt correct or wrong, its all about trial and error. The BSOD that you had, most likely indicates the limit you can do on that vcore further overclocking will require additional juice. As for the HT link it depends on that motherboard, in my case i can run 1.5Ghz HT for 24/7 without increasing NB Voltage, though no noticeable performance increase but no heat/instability issues as well so.. heck haha. But ive read some source that says HT link overclocking does increase the performance of the build in graphics. As for rams, typically, any value rams are not a great overclocker and will hold back your processor ALOT, although in some very rare cases, the value rams uses good chips.

2) Is the blue screen happened because of not enough voltage during OC?
- Blue screen happened due to system instability, the causes are too much to mention. It might be the CPU/ram voltage and it might be your CPU/RAM setting/timings etc. Its all about trial and error. The longer you mess with your system, the better u get to know it, and the easier it is to figure out the culprit which is giving you the BSOD.

3) My Temp is idle at around 36deg C and load is 45deg C. Is it normal?
- This is rather normal, as the matter in fact, this is indeed the recommended temps in all occasions. Though keep in mind higher wont burn, proc these days are designed to take up to 80-90c, but do remember, lifespan will be reduced significantly if you maintain these sort of massive temps for a long term.

4) Is my Processror F3 version?
- its rather unlikely.

5) Is there anything to do with the HTT?
- what are you reffering to?

6) since my RAM is DDR667, the actual clock is 333Mhz. During the OC can the memory frequency go beyond 333MHz? I assume 333MHz is the limit and anything go beyond that is consider OC.
- yes

7) What if the memory is beyond the 333MHz, will there be a risk that the memory will burn?
- usually, RAMs are safe to be running 1.8 - 2.0, but for 2.0 to 2.2, it would be preferable if you have a RAM heatspreader, anything higher than 2.3, better get some active cooling. Of course it can and it will go beyond 333mhz =)

8) I notice some people said lowering the CPU multiplier able to push the bus speed further.. Why is that so?
- Because every system are unique, made out of different motherboard/proc and rams. Some board works that way and some doesnt. But of course, the final clockspeed that you get, is the multiplier x FSB(HTT), in a way, reducing the multiplier also reduces your clockspeed. Its all about balancing up.

9) What will be my safe margin of the CPU temp when OC. some says 50C, some say 55C and some even said 60C.. confuse.
- Always take the full load temps as a safety margin, during overclocking, idle temps can be ignored. You can go all the way up to 60c no problem, but it is indeed adviseable to keep the temps as low as possible, theres nothing to lose. Usually, recommended 24/7 operational temps are between 30-40c on idle, 50-55c on load.

10) Yesterday my bus speed hit 230MHz, CPU Multiplier is 13, HT link 920MHz, and the Memory speed is about 300MHZ, i tested with Ortho for 6 hours.. stable and no error. But when i tested with the 3Dmark03, the graphic teste was ok.. but when come to the CPU test where the Orgs were playing stone game, the PC black out and reboot.... may i know why? I thought the Ortho already stressing the CPU and should be fine in running other programs...
- 6 hours orthos passing isnt very hard, you will have to run orthos for at least 8hours to determin its stability, even if it passes 8 hours it does not mean that your system is 100% stable, to be safe, run a session of 8 hour orthos, followed by 8 hours memtest. The rams might be the culprit as well.
