Voltage problem (Abit VP6)

I have an Abit VP6 and two 1gig P3s (133).

The standard voltage settings allow me to set a maximum core voltage of 1.9v... any way to go higher?

I have two Thermalright SK6 sinks with 8k deltas... cooling should not be too much of an issue...

Dump:
ddruid@symbian:~$ cat /proc/cpuinfo |grep MHz
cpu MHz : 1125.910
cpu MHz : 1125.910
ddruid@symbian:~$

1.125 is about the maximum stable speed I can achieve (155 bus). I have been able to post @ 180 bus... but I dont get much farther than the lilo boot prompt tho...

I am using OCZ Pc150 cas2 ram...

Any suggestions?

Look before you ask! its right here at overclockers.com

whew,

Danke

This sounds incredibly scary.. but I suppose it's worth a shot...

/me waits to hear lyr0n's outcome

Ya know...

Are there any other ways this might be done?

Bios hacks? Flashing tricks?

I mean... I have 2 shots at getting it right... 300 dollars a shot... Not exactly something I'm eager to delve into.

I have the same setup as you the VP6 with Dual 1GHZ PC150.
I can't get stable above 147 without minor lockups.
I have been up to 158, but the dram was turnd down.
What is the rest of your specs?
How hot is yoru CPUs with those heatsinks.

I am using the MCS370 with Ystech fans, and I dont' get above 95 degrees. I don't get 1.25 at 155 mz i get 1.2 at 160Mhz though.

Let me know some more.

Well...

I've posted @ 1.27 (175 bus if I remember correctly)

Didn't get much farther than the HD scan tho

I've got a Leadtek Geforce 3 (Before Ti-X models) and a couple IBM disks running @ ATA100.

Sensors Dumps this out:

Them deltas are sexy.. but they ain't quiet.

Hope this helps you,

Thats great and all, BUt what have you seen.
WHat is this system dump stuff. I want to know what you have seen in your system. Can't you tell me that?
What are your normal temps.
No way you have gotten your FSB to 175 running dual chips.
If you did, what did you have running in it at the time, as far as system specs when you did it.

Hmm...

The sensors program is a kernel package.. I run linux...

And yes, I got it to post @ 175... I was running my ram @ cas3 (It is rated for cas2)
Dual 1 gigs.... I even made sure of it by attempting it again.

And that WAS my normal temp.

175 isnt out of the question for a VP-6 with duallies, and good quality components. I'm running a 167 as we speak...

May I also ask what voltage you are using?
Also, what kind of cooling?

Did you use the wire trick if it is in fact above 1.9v?

HOLY CRAP =P

Well I guess you were right, I got it to 173.

It hardlocked quite fast.. didn't even have time to do the ram check and display the 2 proc thingy... Sooo... I took another pic, didn't want you to think I was scammin ya on a single proc system

171 bus actually boots up... but the daemons begin to segfault and linux boots... o well.

Edit: My html images didn't work.. o well.. links it is.

My machine is running at 1.75V, and I'm using FOP-32's. Now before you go screaming BULL****!, I have the computer hooked up to an AC unit and my chip temps are usually around 70 Degrees under normal use. Have to turn the AC duct away at idle for fear of condensation.

And thats Farenheight. 21 degrees Celcius for you metric guys. Turn the AC off and they get up to about 115 degrees F. But will still run stable.

Sounds sexy,


I'm not one of the guys who screams bull.. heh

I think I'll avoid that voltage trick.. 300 dollars a try it a bit too much to bear.

I'm not to fond of the voltage trick or "vid-pinning" myself. I wont do it. It's easy for these single CPU guys to try stuff like that, but duallies get expensive, and seeing as cC0 800EB's are getting hard to find, it's not worth the few extra Mhz.

I actually can't go any higher on speed anyways. Chips could take a hell of a lot more, these 2 800EB's are golden in my book, but other parts start to die on me. Sound and NIC start to dive off at 169.
