I tried many times, with no mod, but still failed to boot this P4 641 on ASUS X48/X38... but my any other P4 641 worked fine. I really have no idea what the hell with this Malay P4 641...

1. Batch number is just for reference only, not all thing. I have posted all the batch number for my Celeron D submissions 2. Generally speaking, D0 stepping will be better. 3. Ambient temperature about 25 C, use U120E cooler, a good Celeron D can post at least 4.60GHz @ 1.25V on air, get into WinXP at 5.0GHz @ 1.40V on air. If you look for golden chip, add more 200MHz on previous Freq requirements. Besides, a good mobo is necessary. CPU power supply, BIOS Vcore top limit, all important. ASUS X48 recommended.

Thank you all guys This i3 530 only do CPU-Z 6.5GHz MAX, not the best chip yet.

My P5E64 WS Evo was dead, 7 months ago, that's really a nice mobo for Celly, sighed...... For higher Freq, I think a better CPU pot, CPU lapping are the same important as high Vcore. I have not lapped this Celly 352 yet. Vpll I set was 1.6V ~ 1.7V, no research about this.

Thanks, guys

That chipset pot was just only used to keep Mobo PCB from bending too much It's a crazy freq. using P35, but not the highest. I have not bin my best Celly on P35

Too busy to bin my Cellys. Have seen my 8524MHz in CPU-Z Records Next time will try suiside 8533MHz, which need really high Vcore...

THX, by now I just only see Philippines' chip May test P4 2.8G next month ...too busy

That's a good idea which good stepping for P4 2.8 ?

A really slow Pi 1M score...keep pushing.

Vcore 2.095V, just like what I said above. Photos of mobo and mods in url:http://www.xtremesystems.org/forums/showthread.php?284942

THX, man If you have a D0 Cedar Mill chip, which can run Pi 1M at 5.2GHz+ @ Vcore 1.45V on air... Then congrats man, You get your golden Celly! This chip can do more than 8.0GHz by proper tuning.

Photos and video will be in the next time, bro... one man, many things. Vmch was 1.29V~1.31V for no reason, I just like that.

I used to do Celly 347 533-->800 fsb pinmod, and do VID mod too. The result was that I managed to run Celly 347 on Biostar TPower I45, which was a P45 chipset. That was how I did: http://www.miivion.com/data/attachment/forum/201302/10/013727wex2yrf31qqxwfox.png. I think you already know VID mod, right?

Let me explain this. Many ASUS P35/X38/X48 mobos can run Celeron D after clearing CMOS and F2 to load the default setting, mobo will run at 533 fsb. But if you want to change any thing in BIOS, mobo has to run 800 fsb at least.

To LUDEK111: Thanks, bro. Maybe I am not quite clear about what you mean, at least I have two SL9KM s(china 56X)can do 5.3GHz+ in air under 1.5Vcore.

To LUDEK111: In fact I am not so clear about the best VTT value, 1.30V was just my favor. What is the batch of your 352 5,64GHz@1,48Vcore? Looks promising to me.

PCB codes: 2L70716 3A0463. Do you want the Vtt definition or BIOS setting? Vtt setting was about 1.30V.

Thanks. If you want to ask how I get the CPU-Z valid file, I used hot key F7.

--Majid OC says: thanks very good ; week 47 !!!chip is dead? two break over 8.0Ghz P5E64 Evo can make Vcore over 2.1V for sure, but no test for this 352, so it is still alive. I am going to try another promising Celly at Vcore 2.1V+, I wish I found my forth Celly over 8.3G. lol

To MAJID OC: Batch: 5647B641. PCB code: 3565216 3A2019 The first show of this chip was in this: http://hwbot.org/submission/2277245_wytiwx_cpu_frequency_celeron_lga775_352_8160.94_mhz, You can find more details. The mobo still has random OVP, though I did OVP mod. Maybe next time I should try 2.1V+ Vcore. God bless my chip...

To K404: P5E64 Evo has no OV_CPU jumper. There are three soldered dots on mobo marked "OV_CPU", but I failed to get higher Vcore by shorting the dots. The highest BIOS Vcore is 1.90V. I did the Vcore, Vdroop and OVP mod. So...
