Update on my new chip *P3 700 cB0

[Slake]

After killing that poor sweet Celeron 600 cC0 before it ever reached its potential, I recieved a P3 700E Monday 7/25/01. For anyone intersested, here's how it's going.
Comments and advice appreciated.
Here's my current statistics:
4Q Mid-tower case - 300W PSU with a very good fan
P3 700E cBO SL3XX week 35? (3035A299-0023) Costa Rica
ASUS CUSL2-C Black Pearl Bios 1006.A
Heatsinks on Northbridge, Southbridge and Mystery chip near DIMMs
128MB Step PC-133 cas 2 running CAS 3-3-3 7-5T
Vodoo 3 2000 PCI OC'd @160MHz
Ensonic Creative Sound Blaster AudioPCI 128
Seagate ST34312A 4.0GB and Western Digital 1.2GB
CDROM 32X
ZIP Drive 100MB
Case Mods;Sunon 120MM 90CFM PVC vented front Blowhole
92mm Exhaust below PSU
ThermalRight SK6 Heatsink lapped with an 80MM 41CFM? fan
Auxilliary 80MM (not vented yet) fan feeding cpu fan
Slot Cooler
ALL cables rounded and spiral wrapped

**Currently running 127 FSB (889MHz) 1.95V
133FSB !(938MHz) as of 4:00AM 7-1-01
**At ambient temp of 24C- Idle =31 Load=40

The first time I tried 133 FSB I got the system halted BSOD, corrupted registry and system files. Had to format and re-install Win ME. The highest I could go was 124 FSB. I removed the heatsink which I had noticed would "pivot" very easily on the chip. The Arctic silver 2 was squeezed to about a 3/16" perimeter around the edge of the core. It looked like the HSF was only making direct contact with about a 5/16" circle in the center of the chip. I re-lapped with great care using 300-400-600-1500 grit sandpaper under running water.I mounted the fan so that the center part of the fan (dead spot) is off to one side of the heatsink(increase pressure). I added a 2nd 80mm fan about 4" away aimed at the sweet part of the CPU fan. On the first boot @ default speed after re-lapp I restarted and went straight to 125MHz. I got one BSOD with 1.85V when I did a cold start upon installing some drivers, so I upped the voltage to 1.95. Ran FAH and Prime95 a short while (~30min each) Then upped it to 127MHz. That's where it stands now. I'll go for more tomorrow. I'm gonna try to lower the voltage tonight.
Thanks for all of your help

Oh yeah, I know my drives suck. Had to bring em along from last system til I can do better.

How'd ya kill that Celly?

I murdered the poor little bugger by lapping it. The autopsy indicates during installation the core cracked on an edge due to being weakened by excessive lapping. Charges are pending. LOL. I had it rock stable at 972MHz for several weeks prior to it's death.

That P-III 700 really should be doing 133 FSB at those voltages. For the first two or three months, my 700 keep getting better and better. A little burn in won't hurt and will probably help.

Do you have a fan on or pointed at the northbridge heatsink? The higher the bus speed goes, the more important motherboard cooling becomes. Sounds like you've already done some mods, that's good.

Thanks batboy. I finally got it to 133 FSB. Can't lower voltage though. I don't have a fan on, or pointing directly at the Northbridge yet. It's on my short list though. The little fan at Radio Shack cost $9.00 and pushes only 5cfm. I have a High speed 50mm but that is too loud. I'll try to find an old 486 or Pentium fan to put on it. I think I'll take your advice and let it run at 133-133-33 for a month or so before trying any higher FSB.
Thanks again.

With my system when i get a BSOD its usualy memory related, almost 100% of the time, it may not be the same on your setup but who knows it nay be something to play with, on my system when i benchmark and find out how high my sisandra scores can go before i get a BSOD i then know my limits, it does not matter how i configure my memory in BIOS cas 2 or 3, minus or clock speed, also my ns rate once i get above my score's i can exspect a BSOD. may not be your problem but food for thought. i guess since your not running out of spec speeds it should not be memory but who knows, as Batboy said i would definalty get a HSF on your northbridge i'm a big fan of making my own from another CPU HSF i picked mine up for 5 bucks and cut it down to fit perfectly.

well i may not be much help just thought i'd say howdy :)

goodluck

[Slake]

Thanks outhouse. Food for thought (and action). Wonder if this gold plated heatsink on the northbridge is good, or if I should replace it. I definately am gonna put a fan on it. As long as I keeo the voltage up, I'm not getting the BSODs. I can run FAH for ever- no problem at 133/133/33 cas 3 . Soldier of Fortune locks up the system at the intro movie. Runs fine at 700MHz. Hmm.. just checked and device manager is detecting my Voodoo3 2000 as a V3 3500 AGP. I dl'd the X-gamers drivers yesterday. Using 3dfx tools for the 3500 as instructed at the web-site. I thought I had changed back to the 3dfx reference drivers. Guess it didn't take. I'll try again to revert to the old drivers. I may go ahead and put that 7500 RPM 50mm fan on the Northbridge temporarily until I can get a quiter one.
Thanks for the input man!

Sounds like a good work in progress, Slake. You've now got the equivalent of a P/// 933 chip, and headed for more.

Well done!!

Mr B

[Slake]

Thanks Mr B. I just hope I can do this chip justice. I foundout what my problem was. Stupid mistake. The Heatsink I installed on the southbridge was too tall and prevented me from putting the PCI Vodoo3 in slot 2, which is where it needs to go in order to have an exclusive IRQ. I had installed it in slot 1 which shared an interrupt with slot 5 where my NIC is. DOH! I knew better. Removed heatsink, replaced card and Viola! I also put that loud ***
fan on the north bridge, but I'm about to disconnect it. I can't stand the whine!
I think I'll canp here at 133FSB for a while before pushing further.
Thanks for the advice and encouragement guys. :)

I'm using a high output Sunon 40mmX40mmX20mm fan which is twice as thick as most 40mm fans. If I remember right, it's rated at about 8 CFM. Here is where I bought mine for $6.50 (see below). Just had to buy some screws at the hardware store that were long enough. Also, most motherboards have that northbridge sink attached with sticky thermal tape. Take the sink off (usually have to get to the back side of the mobo to release the push-pins), clean up the goo, maybe even lapping the sink, and then apply Arctic Silver. This is what I've done along with the HO fan and I've had my system up to 155 FSB stable and 157 FSB unstable. Make sure you have good air flow across the motherboard too. Good luck.

Hi,

if the high rpm 50 mm fan is a 12v fan, you could run it at 7v, so that the sound level extremely decreases. You'll find a description in the COOLING section. The performance will also decrease, but I think it should be OK for cooling the chipset.

ROFL..........and I'll bet none of you knew that right? =)

Sorry friend.....couldn't resist.

That Sunon Fan is 8.7 cfm to be exact :)

Thanks for the fan advice guys. I have a rheostat on it but it's still overkill and alittle on the loud side. I think I'll get an old pentium or 486 fan for it. I have the chip running at 1.95 v and default speed right now for burn in period. It was crashing to desktop in 3D games after about 10 minutes. May need to get that new vid card ahead of schwdule. I have so many week parts in my system! LOL

[Mr B]

I'll wager you don't have anything NEAR as weak as my ISA SCSI card though...LOL

*mental note....I have GOT to upgrade that....I have GOT to up....*

It's hit or miss over 133 FSB as to wether or not it works. If it doesn't, no CDRW. If it does, I dance in the street. =) Usually likes 153 FSB, sometimes does 156, hates 159...

*2nd mental note.... get fan for Northbridge...get fan for...*

Letting it ride at 133 sounds good, Slake. My C600 hung at 112 for the longest time, and then one day decided to go to 117. I'd try every so often, and nothing, then one day.....=)

Interesting nick Celemine1Gig Whacha got? How about posting your specs? Enquiring Oc'ers want to know! :)

Mr B Sounds like you and I need to gather up all our unused parts and go to a swap meet.What to upgrade first?? Hmm puny HardDrives, mediocre vid card no CDRW I am SO underprivledged. :(
What I don't understand is, how come this V3 PCI card runs so well on a 42MHZ bus 127/127/42 (way out of spec) even when overclocking the card with powerstrip to 166MHz, But won't run stable at 133/133/33 or 133/100/33!?! I guess that's a topic to take up in the Video/Sound card forum.

[Mr B]

Every now and then I'll see and old PC on the side of the road, etc... and snag it to strip for parts. Last count I had 5 drives under 450MB, 2 486DX's, a P75, P90, 4 floppys of unknown condition, a couple ancient ISA vid cards, sound cards, NICs, a bag of 72 pin SIMMS 8 sticks of 30 pin 1MB ea. ram, etc....

If I ever find someone who's still runnning DOS as their primary OS, I'll be a very rich man... ???

One of these days, I do intend on selling off all of this stuff. What's really scary is that someone will probably buy it, and be psyched. I still see people buying the old Pentium 233MMX chips at e-BAY for $40 or more. Jeez, I got my Celeron 600 there for $56, and it bangs out over 1 GHz.

I've got 3 PIII 700 cB0's, all SL45Y retail FC-PGA chips running in slot 1 mobos. I've had one running for over a year at 1.9V+ on an Iwill Slotket II. It's been running at 994 MHz @ 1.95V since October solid as a rock. The other two are in a duallie on Asus S370-DL slotkets. They're very solid at 933 MHz @ 1.8V and will run semi-stable at 980 MHz @ 1.85V.

I've been using a Alpha PEP66 on the 994 MHz one and the two duallie CPUs are fitted with all copper CoolerMaster CB5-5G12's due to space considerations.

Nice systems DaveB! I kinda wish I had gotten a slot 1 mobo. I cannot reduce the voltage on this board. The Celeron I had (R.I.P) before this 700 insisted on 2.0V . I think my video card is holding me back from stability. Strange thing is, it runs fine at 127/127/42, but won't run a 3d game more than a few minutes at 133FSB regardless of the memory setting (100 or 133) and that's at 33 PCI bus!?.

[Da Bear]

Hehe...my 700 ran 933Mhz 1.65v out of the box, very nice :)
