6BXC + 700C Help

[Sal]

I have a gigabyte 6BXC mobo using a sloket containing a 700C. The best i can get out of it is 874, dip sw clock x on 6.5 (although this seems to adjust nothing) and bus speed sw on 83. Why is it when i take it up to the bus speed up to the next step (100) that the computer runs but no screen???
I have an old server that has 8 Gigantic fans running (plus the usual heatsink+fan), should this be enough??
I have seen in the Overclockers database that someone has used the same cpu and mobo to achieve over 1G with no mention of *super* cooling devices. Any advice welcolme, specially from someone with same gear.
Cheers!


(have tried all combinations of Clock X from 3,3.5.....6.5(which seems to do nothing) and all combos of bus speed - 66(700),75(788),83(874) -all good but 100,112,133- no good)

... Just because they can overclock to 1gig doesn't mean you can.. Try pulling out all your PCI/ISA only leaving your video card and see how far you can go like that.

Sorry dude, the Celeron 700 is such a crappy overclocker. The high multiplier is what makes it such a dud.

You'd probably have to be lucky to get a 'good' chip that could do 1Ghz.

If the opportunity arises try trading it for a Celeron 600/633.

Good luck!

And all Intel CPUs are multiplier locked. Thats why they 'seemed to do nothing' :)

Hey, i have the same board (GA6bxc)

Like one of the other guys said the chip is multiplier locked so you can't change that and the next FSB on that board is 100 which means you will be running at 1050....it'll be hard to do that big a jump (870 to 1050...)

I have had my board past a gig with two chips though, a C2 600@1008 and a C2 800@1066 so by all means the board is capable.

Just a question what riser card are you using??
and how much voltage are you giving the chip? (might need more vcore, dont go above 2v tho!) if you dont have a riser card with voltage you should get one, with more vcore you might get to 1050 if your lucky!!

And as a another note a good HS/F makes all the differance, i can run my 600@1008 at 1.5v (defult is 1.7v) with my FOP-38, but with the stock HS/F I get lockups at 1.7v@1008 even!!

Well next time it might pay to do a little research!!
I thought that one model (700) would be no difference from the rest(633). And at the time i knew not of the core voltage settings on some riser cards (As i think there is no ability for that on mine, it only has configuration settings-i.e whether its a intel, and what CPU clock to run it at but adjusting this does nothing).
Thanks for all the feedback, good excuse to go out and by another riser card (....hmm, maybe a new mobo and CPU).
Cheers.

If your thinking about buying new I seriously recommend the 1.2 Tualatin Celerons and a compatible motherboard. Those are looking real nice and will leave some room for an upgrade.

As mentioned get yourself out a 1.2 Celly Tualatin and an Asus TUSL2 and some good cooling..

Pinky got to 1.5 ghz with Air Cooling and the benchmarks were incredible...
