C533A Owners: Is Your Slotket Holding You Back from +897MHz?

[Killer Ape]

Yes, the 566 is a CuMine and with luck should hit 850MHz.

Set the voltage on the slotket to 1.5-1.65v (try lowest first and then increase if the CPU isn't stable) and the FSB setting to 100.
Same adjustments should be made on the mobo via jumpers/BIOS.
Don't forget to check that the BIOS you have installed supports CuMine CPUs. If not, flash to the latest one.

Don't forget that PPGA fans won't sit properly on FCPGA CPUs, so you may need to get a new fan if you're not buying a retail CPU.

Good luck.

Thanks for your help Killer, I let you know how I make out )

 

[planet]

Hey Killer! I have one other question for you. What should i do if my mobo automatically detects the voltage? is there anyway i can get around this?

 

[Killer Ape]

If the BIOS detects the CPU as a CuMine it should default to the correct voltage. If you need higher voltages, theoretically, setting the voltage jumpers on the slotket should "force" the BIOS to detect the CPU at whatever voltage the jumpers are set to, but this doesn't always work.

thanks again

No, I'm not saying that gaming is better than surfing. I'm saying that the BSODs are completely random. Since I don't play games anywhere near as much as just surf or do real work (shocking) on the computer, I'm bound to get these things happening more often in 2D if the vid card (and maybe CPU) is not the problem.

 

[Killer Ape]

Eug: I see. I agree that your memory and vidcard should be fine up to about 125. You need to be like me and have an old reliable Dell box for work and a Frankenstein for play .

If I'm understanding correctly now, you're stable at 840/105 FSB, but get the occaisonal BSOD at 880/110 on up. You've got 5 drives right? Any chance one of them is picky about slightly out-of-whack bus speeds? That's alot of hardware to keep happy at once. You could be fine during stress testing because you're basically only running off your boot drive and maybe one other drive(?), but when you're doing a bunch of different things over the course of time you're switching between devices more frequently, increasing the odds that there's going to be a bus-wreck, especially if something's sensitive to being run a little off spec.

Just guessing here...

I am using an Abit Slotket III right now, and in fact it overclocks better than my MSI and Iwill slotkets with a P3 650E on both an Abit BE6 and an Asus P3V4X. In fact, I need a higher voltage with the Iwill. Maybe I just got lucky with the Abit if some people say it sucks.

Killer Ape has a good point about your drives not being happy with odd fsb setting .

In my experience Maxtor drives really dont like it.
Check if one of your drives is Maxtor and disconnect it for a test.

 

[Eug]

Yep. 5 drives. But no, it's not the drives. At 110 FSB, the PCI bus is only running at 36.7 MHz. I've run all of them at 37.5 MHz for weeks to months with my old Celeron at 75 FSB. In fact, I even ran several of them for weeks at 41.5 MHz with no BSOD.

I own:
Yamaha 4416E CD-RW
Pioneer 104S DVD-ROM
Panasonic CR-584B
IBM 34GXP 20 Gb IDE hard drive
Quantum Fireball 10 Gb IDE hard drive
Promise Ultra66 card

 

[Killer Ape]

Well, I'm out of ideas (Good,Eug mutters to himself... ).
Except...

You could run a really ugly little experiment and set the 533A back to spec (brrrrr...) for awhile to see if your BSODs go away.

I promise we won't lose any respect for you as an overclocker .

 

[Eug]

No, like I said, I get BSODs ABOVE 840 MHz, and even then I have to wait several days before I'll get one. This is with or without heavy duty gaming during those several days, and I've done CPU torture tests overnight as high as 920 MHz with no problem strangely enough.

At 840 it's perfectly fine. So, it's likely the CPU, the slotket, or the memory.

But of course, at 840 MHz I'm still satisfied. What I really want now is to get my V3 2000 to 183 MHz. I can actually complete 3DMark2000 at 190+ MHz (it just FLIES), but at 180+ MHz my V3 only lasts about 20 minutes in heavy duty gaming. I've got some stuff coming from 2cooltek.

 

[Killer Ape]

Did you check-out 2cooltek'smod of the TNT2U with a big-ass fan and heatsinks covering everything? That's a sweet vidcard mod.

You gotta love those V3 2000s. Aside from no 32 bit color they're still (until the NV11 cards come out ) the best bang for the buck vidcards out there. I've put 3 of them in other people's systems and they kind of make me wish I hadn't spend $50 more for my TNT2U.

A lot of people seem to get good 183 OC success by screwing a Pentium fan on the HS.

 

[Thorn]

Eug, I had the same thing happening on one of my machines (an Athlon 700 OCed to 950). I'd get random BSOD every couple of days, usually when it was just sitting there doing nothing. I tried more voltage, less voltage, better cooling, all new drivers, everything short of a fresh install of 98. By some act of fate it all went away after upgrading to IE5.5. Didn't have anything to do with my HW.

 

[Vrangel]

Thorn
can you post a link to IE5.5
Thank you.

 

[Thorn]

I emailed the setup file to you.

 

[Thorn]

Well, I tried to email it to you... but my email got kicked back.

You can DL 5.5 here: http://download.cnet.com/downloads/0-10058-108-52247.html?tag=st.dl.10058.upd.10058-108-52247

 

[Vrangel]

Thanks
I am changing DSL from BA to Acecape and limping on NetZero for now.
Will update email address when its up.

EDIT
Forget it ,after you click through to Conxion server it says file doesnt exist.

wheres a good place to get abit slotkets, or asus ones? BOth have dipswitches to force 133 fsb?
