Grin Mine's still locked, and I got it to 1.73GHz@151FSB, although it isn't there any more because I messed up the thermal compound, and I didn't have any good stuff to replace it with.  I also got bored and rewrote the name string, that's actually from dxdiag.exe, slightly photoshopped to get the appropriate info.

so there's no way to clock this model to 166fsb? i haven't tried yet, because i was more careful when the thing crashed at 1.66GHz via multiplier...so 151fsb is the highest clock still stable? i bet i got problems with such an fsb, 'cause my pci clock isn't locked to 33MHz.. Undecided

I could have gone higher, but the temps were starting to worry me (49C Idle), I've got a CoolerMaster heat sink at the moment, and I was using the thermal compound that came on it.  It was still very stable and at stock voltage, so I've got a Volcano 9 on the way, along with Artic Silver 5, so I'm sure it'll probably go higher once I've got the right equipment. As for the PCI clock, I don't think mine's locked either, all you can do is pray that everything goes okay, but it isn't increasing it that much anyways. At 151FSB, the PCI clock is like 37MHz.

Actually, the main reason that OC gurus love to modify the multipliers so much is to lower them! By lowering the multipleir, they've found it takes enough stress off the CPU so they can raise the FSB much higher, which not only makes the CPU run faster, but all the PCI/AGP devices also!

yeah, i know that, but:

Shocked my cpu goes to 65°C!  (but therefore my system is ordinary silent  Grin )and it's still stable @ 80°C (evently this only appears on die-hard o/c)! don't worry about this temperature, as the palomino has an internal temperatur diode which reflects it very exactly & you know, palominos are known to be stable up to 90°C.
but that's the point why increasing the fsb worries me --> i don't want to try the hard way  Wink
2nd point is the pci/agp clock: i don't want to crash my soundcard or my gfx this way

so what do you think, is increasing the fsb by, let's say, 5-10MHz still stable?
hint: I'm using an arctic cooling copper silent 2 (cools up to 3400+), my ram is also overclocked via timings (not by clock)

Internal diode? I don't know anything about this, the only diode I know of is the one placed under the CPU, inside the square area of the socket. At stock speed, my Palomino runs at about 30C (about room temp in my house). It's got a gigantic aluminum CoolerMaster heat sink, which I imagine helps, but the shitty little 60mm fan on the top doesn't really.

EDIT: It used to run at 30C, before I messed up the thermal pad and replaced it with Radio Shack compound. Now at stock speed it's at 42C.

Every CPU is different. Depending on the week, the design (core), the temp at the plant at the time of manufacture, and the condition of the silicon used, each individual CPU will have different limitations, even under the same cooling and everything.

I personally have never had an issue with sound or video, although my old Netgear NIC caused some problems while overclocked, so I replaced it with an SMC and never had problems since. Also, my P2, when I raised the BUS on the 350 from 100 to 133, the PCI/AGP divider didn't support this change, they stayed stuck at 1/3 and 2/3, so my AGP BUS was 87MHz and PCI was
44MHz, and that never had any issues either. It was using a Voodoo 5 5500, 3M NIC, Netodragon 56k modem, and an Creative Labs Ensoniq AudioPCI.

Only way to know is to find out  Wink But those temps are very concerning.

I don't know much about OCing ram, because I got 166MHz ram anyways, so I'm all set. I would take a look at replacing your thermal compound, since your cooler itself doesn't seem to be an issue. Poor thermal transfer can lead to pockets of heat, which would give results like you're getting.

well, i used the thermal compound delivered with the cooler (so it's arcting cooling stuff, no silver)
what do you use to read out the temerature? if you use your bios the temperature isn't exactly, you know. take a look at aida32 or the mbm, they should also read out the internal diode. i saw a difference of 10°C when reading the temperature with the internal diode! so your temperature might be also 10°C higher..
anyway, i got also DDR333, but i set the CAS Latency from 2.5T to 2.0T which sets free 100MB/s more (setting the waiting sd-cycle to 1T instead of 2T gives another 100MB/s) and my kingston ram can handle that.
i overclocked the pci bus some 2 years ago on an old socket7 mobo (set fsb to 75) and their was no go anymore...well, i suppose pci components are able to clock higher nowadays  Smiley

I just realized this is getting way off topic. I use PCAlert 4, which came with my MSI K7T266Pro2-a, it monitors temps and fan speeds. I have mbm somewhere, I'll see what it does, but I think it will probably give the same readings, I'm not aware of any processors having an internal thermal diode...google time I guess.

well, every athlon has a temperature diode since the palomino was introduced.
yeah right, off topic  Roll Eyes

Okay, I found some info on the internal thermal diode. I still don't know where the readings are being taken from tho, the CPU or the mobo, cause I think at least that the mob has a temp sensor under the CPU. Oddly enought, atm PC Alert reports my CPU temp to be 42C, whereas MBM 5 reports 37C. Both report 30C as case temp (room temp, since my case is all opened up atm).

Back to what CPU we have.   Smiley
AMD 2600+ (oc to about a 2800+)
AMD 2400+
AMD 2100+ X2 (ones in the server)
AMD 1800+

For price/performance definately going towards AMD. Not to mention I can still use my V5 in a newer board. What I'm really waiting for though is a AMD 64 FX chip in the new boards with PCI Express and DDR II. Then we'll see these things scream.   Grin
