P4 1.8a @ 2610 1.5v, Wont boot any higher.

I think i need a new mobo, this one seems to have hit the wall @ 146mhz FSB. I've tryed everything to get it to boot @ 147mhz FSB or above. Maybe i'm missing something or there's a trick to it.

Specs:
P4 1.8a @ 2610 (MALAY) Fully stable using 1.5v
I'm using a stock HSF, No thermal paste and no TIM. Temps dont get over 45c
P4S533
256mb Samsung/Kingmax/Corsair PC2700

I've tired swapping the video cards and it makes no difference, not that it should at an AGP clock of 74mhz.

Has anyone else had this prob with the P4S533 ?

Can anyone recommend a good M/B, i'd prefer DDR.

Thanks

That's an excellent overclock. I would be happy with it, and focus on tweaking the memory timings. My board has them as "normal, fast, or turbo". I set mine to fast, and changed some of the settings manually until I couldn't post any more. If your board has cpu vcore dip switches, try increasing the cpu vcore to 1.65-1.70. I used the wire trick (inserting 2 u shaped wires into the socket) to change my cpu vcore from 1.44 to 1.71, and was able to boot at higher fsb. Intel has some technical sheets at their website that says it's ok to run your p4 up to 1.75 volts. I noticed only a 3 degree celcius change with the stock Intel heatsink. I keep my board and cpu only 4 months or so, and replace them, so longevity is not a concern.

Thanks but i've tryed running it up 1.9v with no post, my memory settings are @ 2-2-2-5 1T :) or 2-2-2-6 2T @ 400mhz + ;)

One mobo that I would reccomend is the Epox 4G4A+ , it uses the i845g chipset . It doesnt have the dividers of the SiS645X chipset but it still performs better and OC's better. Although I know this board supports DDR333 with its 4:5 divider .

Yo FaTs...why no thermal paste?

I only have AS3, which i found not to be very good on large surfaces like a P4. ;)

Ah...I will have to keep that in mind if I get a P4. Thanks :)

Is this proven, or just in your experience?

My experience. I found it doesn't work well beteewn waterblocks and peltiers ect. I also found that generic paste works slightly better on chipset/gpu's.

I haven't used AS3 in this sort of situation, only AS2.

Well I had the Asus p4s333 and I had a heck of a time getting to 2.6. Then I bought the Asus P4B533 and what a great board and this same chip that struggled on the p4s333 did 2.8ghz on the p4b533. If I was you I would seriously look into the P4B533. I think that if you reach 2.610 and stock voltage then you probably have a chip that can make it to 2.8-3.0ghz pretty easy. My 1.6a that I have now does 2.655 at default voltage. So I say get the new board and you should be ready to really make that baby soar. Good luck!

Heck it's only money :D

But i was thinking that myself, the one with ATA-133 Raid, usb 2.0 and 1394b looks tasty.

I would recommend a TH7 with Mr naturals bios. I got my 1.8 to 2672 with voltage at 1.6. I got it to post with fsb at 152 but wasnt stable at all. But it seems that DDR boards are the in thing now so Ill sit back and be quiet because I sold my TH7II for a gigabyte 533 board only to have it spit in my face when the ram is clocked above 1066.:( Still plenty fast at 2.4 though. Ill have to make a come back here soon. Looks like a 870mhz overclock isnt much around here anymore hehehe

Have you checked out the ASUS P4T533 (RIMM4200) board ? It supposed to be out soon and comes bundled with a 512mb RIMM4200 stick which according to some reviews OC's in the 166 x 4 range :eek: Not only that but the board has all the OCing options you need including FSB up to 200 , AGP/PCI lock , All Vcore/DIMM adjsutments ,etc...

dont worry as soon as its available Ill be looking into snatching one up and trying it out. I know DDR is the flavor of the day, but I still have a taste for that bandwidth loving RAMBUS.
Oh yeah I know its OT but I finally made it to freaking genetic jeez Ive been here FOREVER. Now I think Im going to retire I just wanted to see genetic under my name hehehe:cool:
*edit* whats with the hammerhead crap :( hehe sorry mods you know Im not a spam champion. Just been trying to make it to 1000 without being banned after all this time ;)
