[Very OT] Any overclockers out there ?
Hello, everyone. Firstly, my apologies for posting something completely off topic, but this list has always been a good place to turn for just about any problem in the past. Please feel free to mail any replies directly to me so that everyone else on the list doesn't have to be bothered by them. So, what's my problem ? I am trying out a little experiment, and it is not going as smoothly as expected. I am attempting to run a Tyan Tiger 100 rev. F (S1832DL) motherboard with a pair of PIII-667EB CPUs. This is a BX based mobo, and as such, it is only intended to run at 100MHz FSB. The EB CPUs run at 133MHz FSB. The board has been running for a few months now with a pair of PII-333s, and has proven to be rock solid. In addition to the two new CPUs, I invested in a 256MB PC133 DIMM from Crucial (does anyone believe how cheap memory has gone in the last month ?) and a Gainward GeForce 2 MX video card as they are supposed to handle the overclocked AGP port better than my old Viper V770. The Tyan BIOS is at 2.0.02, and has supported up to 133 FSB since about v 1.18, at least as far as the "CPU Speed" list in the BIOS itself says. Anyway, onto the actual problem. When I install the new CPUs, the machine does nothing more than blink the hard drive and power lights in sequence. It seems to do nothing more than try to start, fail, and then try to restart again. I have tried running it with just one CPU; same thing. I took out all the PCI devices, wondering if the board was not doing FSB/4 to get the right PCI bus speed; no difference. I know the memory is good as I left it in the machine. It is running right now, quite happily, with my trusty old PII-333s. Have any of you managed to get a configuration like this to work, or do you know of any websites that have any further info on this ? I found one that made mention of someone running a pair of 600E CPUs (100MHz FSB) overclocked to 800MHz by turning up the FSB to 133 in the BIOS. I bought the 667EBs and PC133 memory so that I wouldn't actually be overclocking those, but only overclocking the BX northbridge and the AGP slot. Any help would be much appreciated. Thanks, Stuart.

Thanks, Stuart. Stuart,
I don't find this too off topic. I'm interested. Do you have jumpers on your mother board? Are they set correctly? I seem to remember way back when I was a tech CPUs with different clocks requier differnt jumper settings. Look in your mobo docs. HTH, Steve
Well, since it seems to be of interest, I'll keep the thread going on-list for now, until I get any grief letting me know to do otherwise. The only jumpers on the board are to set the clock multiplier. This is to set the frequency of the CPU as a multiple of the FSB speed, e.g. 100MHz FSB x 5x Multiplier = 500MHz CPU. However, this is apparently only needed for PII CPUs, as the PIII is allegedly fixed. Thus, the only way to overclock one is to adjust the FSB speed upwards, thereby increasing CPU speed through its fixed multiplier setting. The mobo is supposed to detect this and configure itself appropriately. Just to be sure, I have set the jumpers to 5x, thereby setting it up for 667MHz at 133MHz FSB. Bye for now, Stuart. -----Original Message----- From: Steven T.

Hello. Here is one site I frequent off and on. They have a Linux area on there Forum and you might find some information to assist you there. I know of a couple of oher sites for overclocking but the links are at work. I will forward them to you as soon as I can find them, Mon. probably. http://www.2cpu.com Good luck.

Stuart, You may have already found your answer, but I think I should tell you I misstated what I meant. I should have said 'dip switch' instead of 'jumper'. This may be of no use to you, but it may also help. Let us know how things turn out. Steve
First, I must say that I'm in a big rush and I'm not even sure I read everything you said but I'll point out a few thigns: 1. Intel CPUs (Blast you, Intel) are multiplier locked i.e. you can't overclock the "x" setting. If you reall want to you can do some soldering. See tomshardware.com as well as www.overclockers.(com net or org, I forgot which) 2. You can still overclock the FSB (mainboard speed) even on clock-locked CPUs but some soft BIOSes will fight you. That's why, for overclocking, mainboards that still use switches and jupers are better - it's hard to make BIOSes that do SoftFSB co-operate. Beware of the fact that that can screw up PCi cards and the like, Some higher-end Mainboards allow the PCI bus to be gated (run at it's own speed seperate form the rest of the board) 3. I strongly suggest you check for updates to your BIOS and install them if there are. 4. Go over your jumpers/dip switches several times with your mainboard's manual in had, it's pretty easy to mess those up. 5. You may have some settings locked in your BIOS, things like "quick boot" will case it to not perceive some hardware changes. if you have QuickBoot enabled disable it. Sorry for how messy this is, hope it helps. Read the web sites, read the mainboard's manual :-) At 01:30 AM 2/18/2001 -0600, you wrote:

What Jonathan has said is not exactly true for the Celeron CPU's. The FCPGA (flip chip) does have a locked multiplier, but the PPGA Celeron does not and the multiplier can be changed. Celeron's are the overclockers choice of CPU's in most cases. Nevada

True, in my rush to get out the door I forgot to mention that it's only newer chips ( <~1 year) that are clock locked. IIRC the newest Celerons are too, though, aren't they? ---------------------------------------------------- Jonathan Wilson System Administrator Cedar Creek Software http://www.cedarcreeksoftware.com Central Texas IT http://www.centraltexasit.com
I could be wrong Jonathan, but I don't believe the PPGA is being made anymore. When Intel descovered that the PPGA was being overclocked by changing the multiplier, they came out with the FCPGA with the locked multiplier. Nevada Jonathan Wilson wrote:

The flip chips overclock real nice. Just change the FSB. A 566 can easily handle 850 according to many people. Nick

The Tyan BIOS is at 2.0.02, and has supported up to 133 FSB since about v 1.18, at least as far as the "CPU Speed" list in the BIOS itself says.
But does the system actually support 133? Just because it's in the bios doesn't mean it's actually being used. Some companies make more or less generic bioses. The other thing is does the bios have support for your cpus? When you have the system working with the other cpus can you get into the bios and set the bus speed or is it only auto? I'd bet the problem the bios looks at your cpus and gets totally confused. It doesn't know what FSB or how much power to supply them. I thought Tyan was pretty conservite about things like overclocking. Even Asus now seems to include overclocking info on thier website. Nick
