PIII 800E@992 getting any higher

[FIChTe]

Hi there,
i have a PIII 800E (SL3XR) Slot 1. And my first question is what is SL3XR CB0 or cC0 step?
My CPU rans with a Golden Orb Slot1 CPU Cooler. Its 100% stable at 992 MHZ 1,85v. I have 4 80 mm Case Coolers. So the CPU Temperature doesnt go any higher than 33C.
My second Question is, can i go to 133MHZ fsb without peltier or other crap ?
I have 2x256 MB Apacer/Winbond CL2 Rams, current fsb is 124 MHZ.
My Mainboard is a Gigabyte BX2000+.

thanks alot
Fichte

You could just try to go a little higher! I suggest that you do not increase the voltage to much higher with a Gorb though,even though your temps appear to be fine!If you definitely know your temps are accurate,then you should be ok increasing the voltage to 1.9v if need be.

I'm not sure what stepping that would be. Download SiSoft Sandra, And run the cpu and bios information prog. That will tell you what stepping you have.

I have an 800E with a cb0 stepping. Very stubbern chip. I have it stable at 1gig right now. But I had to use a 50w tec to get it there. With out the tec it would not even boot into windows. I also need my voltage jacked up to 1.9v or it is not stable. I had it at a gig a while back but was never stable. Would lock up while gaming every now and then. I have a different case then I did then though, so that might be the difference.

Your board only has options for 66mhz, 100mhz, 112mhz, 124mhz, and 133mhz. Am I correct. Getting her to run at 133fsb is probobly gonna take more cooling then that orb can handle. You may want to ditch that and go with a PIII Alpha. They are loud but man do they cool.

My system temps are cpu = 23c, system = 29c. This is at an idle with the PIII Alpha and a 50w peltier. And I can only get it stable at 1000mhz. I think if I go with a 72w or a 85w peltier I can get it at 133fsb or close. See my Motherboard (abit BE6-II) has the option to adjust the fsb in 1mhz increments from i think 85 to 200mhz.

According to the specs on this page you have a cBO chip:

Thanks alot guys, its a cB0 stepped PIII but i dont understand why people have so much trouble to get this thing overclocked. I overclocked it with 1,65v to 992 but no 3d apps are running. Then i increased the voltage to 1,85 and boom this thing blows everything :). I tried 133 MHz fsb it boots but i didnt try to boot Windows :). *fear* :) Is there anybody who had overclocked the PIII800E (cB0) to 1066 without Peltier and other crap :)

so long FIChTe

I just bought Abit BE6 II (Unfortunately can't find Rev 2.0) on last saturday and put my P3 800E Slot 1 (Step cC0) and o/c to 1008 (1.90V) with my 52W peltier on. I tried with my friend and my machine will boot in 1066mhz (Only Post but can't boot into Windows). I don't know pretty much about the potential of this CPU but so far over 1gz is a big gain from this CPU. Everything is stable with 1008 and I am going to burn in this CPU for sometimes and hope I can go further..

I checked the CPU database, looks like a few folks are running the P-800 at 133 fsb or above on just air cooling. If you don't have any settings in between, I say go for 133 bus speed. Since everything will be in spec (except maybe your RAM if you're using PC-100), at the worse, your system will either freeze and need to be reset or it will crash. Not really much to lose, but your Golden Orb will start holding you back soon if it's not already.

WOHOO Impressive Batboy :) Is this a Slot 1 or a FCPGA CPU. And another question :), can i damage the CPU when i increase the FSB to 133 MHZ, or can i only damage the CPU when i increase the Core Voltage :). I cant increase the Core Voltage. Gigabyte is perfect for nonoverclockers :) and i its the best mainboard manufactur i think :) These Boards are 100% stable :), ok back to my CPU should I use these Arctic Silver Thermalpaste ?

ok thats it for now :)
thanks alot for the answers :)

By increasing the core voltage you are risking damaging your chip but they can take a fair bit before this happens. By increasing the FSB you are risking data corruption through the PCI bus if you cant set it to near normal in the bios.
Thermal paste of somekind is always a good bet. Artic silver is the current favourite.
Trying to get to 133FSB is hard with an air cooled 800E. You are going to need qaulity parts to acheive this in 99% of systems.

I can get in at 1008mhz with mine, Can even boot in at 1024 but it is not stable. It will lock up while i'm gaming. I am going to buy either a 72w peltier or a 85w peltier. I think I could get her a bit higher yet with a little more cooling. My temps are not bad now but a little cooler she may go. Without my peltier I cannot even boot into windows at 1000mhz! And it will only run 100% stable at 960mhz. so the 50w peltier alone made a difference.

Theres one guy around here running a 700E @ 1086 with a 86w peltier on an Alhpa cooler (slot 1), And his cpu temps are -9c! That is awesome without using watercooling! He has alot of fans to pump all that heat out of his case though.

Fichte, thanks. My new P-III is a socket 370 FC-PGA. About running at 133 bus speed, whenever you overclock, you're taking a tiny risk of something going wrong. After all, it does stress components a bit. But, I believe that since 133 is a default setting and all the buses are running in spec, not really much can go wrong as long as you watch temps and don't get crazy with the voltage.

Voltage can always be changed using the wire trick. What CPU do you have? It's hard to do much overclocking if you can't adjust the voltage. See some of the other recent posts on this subject. Yes, you should use a good thermal paste. Arctic Silver is one of the better brands, but it is a little expensive. Don't forget to do some cooling mods, such as adding a couple case fans. Good luck.

All U guys with the Abit Be6-II, I have a Celeron 800 (also 8x100 default) and ran into the same stability issues as you did, until I discovered that the Vio needs to be bumped up to 3.6Volts! I am now at 1048 (8x131) with 1.85Vcore and 3.6Vio. 1008, 1024, 1032 etc. seemed stable but I still got BSOD (kernel_mode_exeption_not_handled) under Win2k while it had been running Seti for hours and hours while I am surfin, emailing, and ****. All this was over when I raised the Vio to 3.6Volts!!! So try it! Only thing I'm now thinking about is sqeezing some mini-fan over the northbridge 'greenie' inbetween the slotket and the CPU-heatsink...

[Lancelot]

Here's my current setup:
Abit BE6-II, CeleronII 800 (100Mhz FSB) @ 1048Mhz (8x131)
BIOS settings: FSB: 131, Vcore: 1.85, Vio: 3.60, AGP: fast, In-order qeue depth: 8, L2 cache latency: 2 AGP divider: 2/3, PCI 1/4
Replaced original small celeron fan-heatsink with larger P3 1Ghz fan-heatsink (original Intel crap, yeah yeah), extra case fan sucking in air below in the front of the case, mini fan on TNT2 AGP card, PSU fan blowing out air
(learned most of this **** right here @ overclockers.com!!!)
Again, for the BE6-II running far above 100Mhz FSB, raising the Input-Output Voltage seems mandatory...

I can bump my VIO voltage up all I want, and not get any higher. She wants more cooling or more voltage. I cant give her more volts so I'll see if getting her cooler will help.

My brother has a socket 370 PIII 800E and can run his at 1000mhz with out any extra effort. I know once he gets some PC 133 in there it will do 1064mhz or at least close to it. With nothing more then an Alpha cooler.

I'm not so lucky with my Slot 1 800E! Takes me a lot more tweaking and effort. But that's makes it appealing right!
