Tình hình là em Zalman 5x này cũng mới lên giá,hiện giờ là gần 400k,khánh kiệt rồi

Sao mà mát thế

vấn đề có phải là temp đâu,do con cpu bác không lên được thôi ,em cũng stock fan mà

hôm qua đang bực bội trong người nên đưa "em" nó vào lò bác quái,hối hận quá ,bữa nay cho em nó xuống 4g nên mát hơn 1 tí,mà chắc A70 chỉ đạt 4g thôi mấy thím nhỉ

Sao anh chích 1.29V dữ vậy....mấy cái post em quăng lên chỉ cần 1.25V là pass 1024 rồi

4g 1.25v không stable anh mới chích thêm từng bước đó chứ

When i first started to overclock , i was thought and put emphasize on BLCK and raise it as much as possible and if possible lowering the CPU Ratio ( multiplier) lower . This is no surprise that if we google to find how to overclock lynnfield cpu at 4ghz or above , we basically sees most of them are doing it by increasing their blck upto 190~200 mhz with 20 or sometimes lower cpu ratio. And they claim their cpus are stable. Indeed it is stable !! But for how long ?? 200 mhz blck means a heavy demand of VTT/IMC voltage increasing , something near 1.3~1.4v which is way out of intel critical absolute maximum voltage limit ( which is 1.21 and anything avobe may or will damage the cpu or reduce its functionality significantly ) . Also since the qpi also increase it demands a PCH voltage demand which is not a good move for the mobo. So increasing the baseclock frequency at higher value means pushing everything beyond their limits those are associated with blck ! And most of the overclockers are actually setting this value and risking their heavy investment ! Enough talk now lets see if we can have a stable overclock with lower IMC /VTT and minimizing the risk .
Before i had my i7 870 overclocked at 4 ghz at these settings .....

BLCK- 20
CPU ratio - 200
CPU VID - 1.34 (intel spec max 1.4 )
IMC/VTT- 1.38 ( because of the excess blck and well beyond intel highest spec )
Ram - 1.65 ( has to set them 2:8 fsb to retain 1600mhz )
i also had to tweak other settings to achive stability

And yes my pc was stable but likewise i mentioned before, it was quite risky to operate to attain only 4 ghz !! So finally i came to a solution wheres i will retain higher speed but lower voltages ensuring longibillity of my rig.

CPU RATIO - 24 X
BLCK - 167mhz
CPU vcore - 1.318
IMC/VTT - 1.15 ( well withing intel safe spec )
Ram- 1.62 ( 2:10 this time )
and bingo .... a much smoother ,safer 4008 mhz i7 with 8 hours prime 95 stability.
Now decide which setting you would like to catch.


( Remember many guys claim their cpu hasn't died yet they applied IMC voltage well beyond their spec, yes of course their pc boots just fine even after years and cpu-z says it is still i5~ i7 and shows the higher clocks and thats it. they are happy with that, but they dont even know their cpu has lost functionalty and performing much worse then it should perform in defult spec. I request them to play high requirements games or simply benchmark their cpu with safe non overclocked cpu and see for yourself )

Anh em cho ý kiến về cái này với

Ok anh hạ Vcore xuống 1.25v stable rồi

Chuyện bình thường có gì lạ....BCLK càng cao thì càng ăn điện...mặc dù ratio thấp cho xung thấp đi nữa. Mới biết à thím ?
