Is this cel 566 worth messing with further? Your advice much appreciated...

I have two retail celerons, both with the following specs:

FPO/BATCH# L018A519
S Code SL3W7
Week 18
Pack date 05/19/2000

I'm running a p3b-f with the latest 1006 bios, a generic slocket that's taken other 533's to 800 at default voltage, and the retail hs/fan. Both do 83 fsb speed without difficulty, but will not even post at 100 mhz.

I don't want to spend lots of time or money messing with these, but if there's some simple measures I could try, I'd certainly give them a whirl. Would these be _likely_ to make a difference?

-better slocket
-using a socket 370 board (MSI 6309)
-using some PC Power & cooling thermal grease


Seems odd that I would get that unlucky on two...but then maybe that's the breaks. :)

TIA for any help,

Dave

Dave, I would second the motion for the MSI Slotket. Also, have you pushed the voltage at all? Most people running 566s at 850 are at least at 1.65 and some as high as 1.75.....1.8 too, but that's extreme. When they work, they are an incredible value. :)

Thanks guys!

Compuwiz, I've tried through 1.8 volts...

Vrangel, thanks for the link...didn't see this, very imformative. I'm about to try an Asus slocket I have on hand, using MB defalt voltage (which I know is correct)--be interested to see if that helps. Will post back after a reboot...

Bingo! That did the trick!

Booted with no problems at 1.6, tried at 1.55, no problems either...all under winnt 4.0 with lots of apps running at once.

And, as the other thread indicated, the slocket I had wasn't billed as fc-PGA compatible--just the standard Asus slocket, with voltage adapters set to CPU default.

I wonder why a slocket would make so much difference? I assumed that if it would work at all, it would OC as much as the CPU would take, as it's just an electrical connection...but there must be somthing more complicated going on...

BTW, what's a good temperature for these chips at this voltage? At 1.6 850mhz, I was hovering around 45 deg C with the standard hs/fan... are these supposed to be able to take up to 80-90 c, like their older chips?

Thanks a bunch!

slotket makes all the diff in the world. The asus S370-133 i got made the difference between 81mghz and 100 mghz. :)

Hows the Abit slocket!!! working for people. I have a 566@876 1.7v, it'll post and get 1/2 way into win at 112mhz fsb.. What do you think is causing such a differance in slocket's? Oh BTW I have the Abit one now it seems nice and has a good retention thing.

I'm using an Abit Slotkey III in a BH6. Have a C566, SL3W7 Batch L018A519 that boots into windows at 850 @ 1.5V but will lock up. I've upped the voltage all the way to 1.55V using stock retail HSF and it is very stable for normal applications. Will be doing some heavy 3D stuff later to narrow down to the right voltages. I'm not keen on the retail HSF and may part with some added bucks for an Alpha or another Golden Orb. The Slotkey is nice and retention device is best I've seen. Decided to use the Abit in the Abit board. I also have an ASUS and MSI slotkeys that have worked very well in their applications. Lark

1.55? 1.65 is norm for 533 @ 800 or 566@850. 1.75 may be necessary, 1.85 is probably the highest i'd go.

remember the p3 core is 1.65 + 10% = about 1.8 volts. Thats within its safety range.

Picked up a 566 with Iwill II and Golden Orb. Should I set the slocket to all auto and use the bios to set everything or use some combo of the two?

Viper. that's an impressive temperature reading....what cooling are you using? All I did was slap on the included hs/fan, didn't even use any aftermarket cooling compound..I reckon this could account for the difference?
