Bh6 & C2 850

[Killer Chef]

Hi,
Is there anyway I can get a Celeron 2 850(fcpga s370) to work in an A-Bit BH6 Motherboard (slot 1)I have a generic sloket.
I'm fairly certain it's a rev 1 board.
the fsb speeds supported are 66,75,83,100. It may go over 100 hundred but I cant remember.

Any tips/tricks I should know about?

I had a BH6 rev.1.01 board until last week, sold it to a friend. You shouldn't have any problems running a Celeron 850 on your board as long as you've updated to the latest bios(SS). However, I've heard of people having problems trying to run some of the generic slotkets on them; the procs won't post with some of them. I recommend using a name brand slotket, like Asus, Iwill, Abit or MSI as they seem to be more compatible with coppermine-based procs.

You can tell what revision motherboard you have by 2 ways:
1. There is a tag on the bottom of the last ISA slot that will list the rev. #.
2. Look at the bios string on the lower left side of the monitor when the computer posts and the last 2 letters/numbers before the "-00" are the bios revision. Then you can go to Abit's site and look up that bios code and see if it's listed under the BH rev. 1.xx or Rev. 1.1.
As far as fsb speed go, the rev. 1.xx boards have 103, 112, 124 and 133 fsb speeds but don't have a 1/4 pci divider so it's hard to get a stable overclock on the 124 and 133 fsb speeds. That is my experience at least with those speeds. I ran into data corruption issues with the hard drive.
I've successfully run a P3 750E and P3 1000E flip chips on my BH6 with an Abit slotket 3 and I've also run the Slot1 P3 1000E proc on it(sold it last week with the slot1 proc in it). Hope this helps you out.

Are you sure your rev is 1.01?
Abit's faq page says : "Do the BH6 Rev. 1.00, 1.01, 1.02, 1.03, etc. and up (BUT NOT 1.1 and above) boards and the BX6 Rev 1.00, 1.01, 1.02, etc. (BUT NOT BX6 Rev 2.0) boards support Coppermine CPUs?
No, the BH6 Rev. 1.00, 1.01, 1.02, 1.03, etc. and up (BUT NOT 1.1 and above) boards and the BX6 Rev 1.00, 1.01, 1.02, etc. (BUT NOT BX6 Rev 2.0) do not support Coppermine CPUs due to the native design of power for the CPU core voltage probably not being sufficient. So to avoid instability, we advise that the afore mentioned boards do not support Coppermine CPUs.

Abit advises against it.. but it is possible.


they say a problem with the voltage.. that could mean a problem in the softfsb menu..

so possibly celeron 2 's on convertors (voltage set on convertor) run better on abit bh6 than slot1 coppermines (voltage set in bios)..

I have a BH6 rev 1.01 SS bios with a Celeron 1 GHz @ 1120 (112 FSB). I use an MSI 6905 rev 2.3 slocket, 1.75 Vcore, retail HS/Fan. Works like a charm. MANY people run these types of setups. Ignore what Abit says on the web site.

[pappypete]

Here's another.....BH6 rev 1.02 SS bios cele 900
w/soyo slotket. No problem!

[oldfart]

BH6's will live forever. One of the greats!

[Yodums]

Everything will probably work good if you got another brand of slotket since generic have serious problems with support those Coppermines.


And Mud pointed out all the good ones you should be getting, Asus Smart Slot 370-DL Rev 1.02, Abit Sloket !!!, Iwill Slotket II, and MSI 6905(Not too sure about those numbers) Rev 2.

Any of those should work fine but its best if you get the lastest rev of each product since they will support better.

Yes, I'm sure that it was a rev. 1.01 board; read it off the sticker on the ISA slot. I read that stuff at Abit's site but figured that they put that up because they didn't want the hassle of helping troubleshoot Cu-mine support. I had a Celeron 433 originally, then swapped it for a P2 300 that was in a Compaq Deskpro that I got for free and I was oc'ing to 450. When that 300 was starting to get flaky on me, I decided to just go ahead and try a P3 750E and it worked like a charm. I then got addicted to making it faster and the slot1 1000E and the flip chip 1000E came next in that order. :D I would still have that board if it would have had a 1/4 pci divider; loved it's stability.

[Killer Chef]

Well it worked!!
juat a pitty that it doesnt have a 1/4 divider so I could crank it up to 133fsb.
ahwell, It's only for the kids anyway.

[muddocktor]

You can bump it up to a 112 fsb at least with no problems. I never have had any data corruption or flaky behavior by pci devices on a 112 fsb, just @ 124 and 133 fsb.

Well now let me just tell you to be careful what you are doing. I've been running celery 700 @ 1.05GHz @ 2.1v on a BH6 rev 1.01. CPU temp was low, because it was watercooled and it's been running normally for days. The only thing that bothered me that the voltage chips on the board were quite hot, but that was said to be normal. Well what happened was that when the CPU was under heavy load for a period of time, the chips got fried and the mobo died. At least the Celly was ok.


EDIT:
As you can see, the power was probably insufficient when the CPU needed it, so it fried the board. Think twice before ignoring ABIT's warnings.

I had no problems running celery 566@875 and 700@874 on this board, but when I boosted the 700 to 1050 and increased the voltage to 2.1 it was too much for the poor old thing :).

[Silver arrow]

However if you decide to ignore ABIT's warning I strongly suggest that you keep a close eye on the voltage chips. If they'll run too hot, the board WILL fry.
They are two square black chips and a core-like thingie on a cheramic circle just left from the SLOT1. They have the following markings on them:

PHB
45N03LT
PHm9840 B7
PHILIPPINES


If they get so hot you cant hold your finger on them you should apply some cooling or lower the CPU clock, otherwise they will fry eventually. Note that the CPU must be under 100% load so that the power consume is at its maximum in order for the chips to get as hot as possible.
