I've been following your posts for a long while, and I figure you're the one to get no B.S. detailed answers from when it comes to tuning for FI.
Anyhow, what I have is an '86 IROC....stock, except for the minor add on's I listed in the sig. Before you beat me up over the Hypertech ****...err...I mean chip, I bought it before the DIY PROM section was started here. The product, as everyone else knows, is only good for the use of placing my modified PROMS in. Their PROM was a perfectly good waste of $200.
Now my question is, what gains can I expect from a stock engine with only tuning of the .bin? I'm strictly speaking SEAT OF THE PANTS differance.

On a side note:
I'm interested in attending one of the world renowned Grumpy POW-WOWS (since I'm like a 'rock throw' from you).
I'm a computer hardware enthusiest (overclocker too), and learning more hands-on about the various functions of the computer in my car would be icing on the cake.

 

Not seat of the pants, but I'd be willing to bet you would see significant gains in gas mileage. One thing I noticed by using the ARAP bin, is that the car idles much better and the engine runs better overall.

 

What ya overclocking? I've got an old C300->450 running since before it was 'cool'. Nice C600->900 also, and just this past week picked up a XP2200+, gotta start dorking around with that for sure!

BTW, where IS Bruce? Haven't seen him post in like 5 days...

 

Retired.

RBob.

 

Retired? From this site or from all of them? Is his health OK. And by OK, I mean OK for Bruce. He deserves the R&R anyhow.

 

Yes, he is OK.

RBob.

 

Right now I have a XP 1600+ (1.40 GHz) running at 2 GHz @ only 1.85 volts (unlocked). I'm using EPoX 8KHA+ (KT266a) board. I've had my Corsair XMS 2400 sync at 175 MHz on the FSB. The CPU is also water cooled. I'll post a couple pics...Yeah, I heard ya' about the 'before it was cool'! Seems like thats all you hear lately outta' the wanna' be's. My first board was the ASUS A7V, based on VIA's first socket A chipset- KT133. I had that paired with a Duron 700 @ 900. Man I thought I was fast then with a 113 MHz bus and 7ns capable SDR SDRAM. LoL, but that was when the DDR bus first came out.
Next DDR SDRAM became pretty much the 'thing, and now memory bandwidth is almost at DDR 400 standards using "128-bit" controllers on future boards. Right now I'm condsidering building a dual socket A, but I think I'm going to wait for the Hammer (K8) with Hypertransport, integrated memory controller, and the rest of the whole nine yards........
Well it's definitly cool to see another computer person around here Craig! BTW, nice software too....I'm curently waiting on the 232 interface to come from WOTelectronics.com, before I can start using it.

 

First pic of insides....it's a ANTEC SOHO server case with a window I cut in the door, and a neon light and inverter I pirated in to give it a nice glow

 

Outside of case...flash is off on both pictures, so they're both a little fuzzy....

 

clearer picture with the flash on...just doesn't show red neon light

IS the water cooling truely needed?? heh

That by chance isn't a 300a is it? Because I remember when those things always seemed to do 600 MHz. About every chip could; and back in the day that was like the 'super o/c'. BTW, what stepping is your new 2200+?? You may just have a 2.1 GHz capable chip on your hands! Good luck, and let me know what turns out on your 2200+!

 

These chips produce a lot of heat running at those frequencies. About 150 watts or so, OVER A 80 SQUARE MM DIE THOUGH!! As far as MOS transistors goes- the cooler you keep them the better off you are, as far as life expectancy and the overclocking ability of the chip are concerned. Right now I'm working on a phase change (freon based) unit to bring the chip into sub 0 temps (pics comin soon).
By removing more heat, and bringing the chip into colder conditions (because of the doping of the transistors), I can run the chip at a higher frequency. I've seen the older thunderbird core (.18) doing 2.3 GHz on liquid nitrogen (-351*F) (those chips at the end of production only ran 1.4 GHz stock).

 

If you want cool...get away from water, there was a guy that refered his whole board about 4-5 years ago. He submerged it in super cooled mineral oil (-40 deg F) using a window air conditioner unit and a lot of ingenuity.

 

Yes, I believe it is a 300a. One of the Malaysia units I think. I was able to get the FSB over 108 or so, and then it'd flake. The 600 would go to 112 or so, just kept em both at 100 for stability.

I almost forgot, I had (still do!) a Pentium 120 running at 133. Woo-hoo! Actually noticed when it was acting as a Mame cabinet unit. Now it's been retired to basement duty (shhh...).

My new XP2200+ is the 'TBred' with the smaller die. Running a Volcano 9 (love the adjustment ****!) and an A7S333 (weak point) with Samsung 2700. It's only stable to 140 or so on the FSB but that's with no unlock. Haven't touched the CPU yet. Looks like there's a pretty easy (single bridge) way to do that, and I will have to mess with it soon. But a couple problems with that. No 5x divider for the PCI or user-adjustable Vcore on this MB as far as I can tell. Maybe I'll find out different, but for now, I'll just take the GF2 overclock and keep the CPU at stock 1.8 I suppose.

Where did I put that conductive pen?!?

 

I also first seen something like that some time back..neat approach to 'total cooling' I think. The problem with submerging a board, is the electrolytic capacitors will end up filling with the fluid, and rupture. The other problem is mineral oil does not have very good heat transfer properties. So it's hard to conduct heat into and out of mineral oil. Not too mention it's viscosity makes it difficult to circulate. If you could keep water perfectly clean with absolutly no impurities, and seal the capacitors, you'd have a interesting cooling setup!

 

Hey Roc-Z where about you live in Dayton? I'm in Kettering.

 

Route 35 (same thing as 3rd St.), about 12 mi west of Dayton, in New Lebanon. Hey cool, I was just in Kettering a couple weeks ago...just off of Patterson Blvd. there on Evelyn Dr. Kettering's a pretty nice place....

 

That new core will be interesting as the new stepping starts coming out....supposed to be running at only 1.6 volts stock! When you get ready to mod the bridges, I thought I'd give you a link to this site...lots of detail about ALL the bridges. Makes a nice reference: Tbred Decode Well good luck on o/c'ing your new chip!

On a side note: My interface from WOTelectronics.com finally came today, so I'm off to go give your software a whirl!!

 

Heh, I've got 2 300a's sitting on my desk right now, they got replaced with 2 533's in my BP6 board.

I miss Grumpy.

 

Thats cool, I like it out there.I'm near the gov't center and Fraize Pavilion. can sit on my porch and hear the shows.. rained the night Tull was there. So whats the best way to crank up my K6-350? give me a good excuse to build something better if it plodes.... But hon,,, honest it just died... cheers, Bob

 

Anyone tried a big vat of liquid nitrogen? Wonder what that would do for a submerged motherboard...

 

3 years now my only computer has been a p3 450 running at 623 on an abit bf6 board with generic pc100 ram. It has what was called an "unofficial" heatsink because it was over a pound and had 2 huge global win fans.
Right now I'm using my mom's computer which I just built for $720 a couple months ago. It's an Athlon xp 1600 overclocked but then put back to stock speed because it didn't make ANY difference. The mobo is a NForce board with built on 4.1 Dolby digital out and a new ram bus interface that is SO FAST when you install equal ram in the Dimm 0 and 1 ports!!! The Gforce 4 TI 4200 has 64mb, overclocked big time, and s-video or RCA video out, great for DVDs. Combo drive DVD/CDRW burner but the real magic in keeping things quiet was the 80gig Maxter fluid dynamics HD that was on sale from someplace for like $100. This system is only as loud as the power supply fan, just the way I like it and for only $720 you can't say it was overboard .
Is Grumpy retired from racing, source code, or just thirdgen.org?

 

Ok, out toward Stroop and Shroyer....I caught Kenny Wayne Sheppard a couple years ago there...It was lighting the whole night of the concert, which gave the concert a cool effect! The K6-III series has a little headroom for o/c'ing, but a lot of that had to do with the L2 cache being finally on-die (which naturally runs at core speed). Same principle with Intel's Celeron 300a. The 'a' signified it now had on die L2 cache.
As far as o/c'ing a K6, it'd only be worth it if you already had a board with some controls over the vcore, multipliers, and FSB settings. Even then, it probably wouldn't o/c much.See the K6-2 you have runs on a socket 7 based motherboard (Super 7 to be exact)....those boards have been out of production for a while.
If you can afford to build a new system you'll be better off. I personally like AMD for a couple main reasons, but the socket A (462) platform is at the end of the road as well as the EV6 bus they're currently on....next year hopefully the Hammer (K8) Athlon will be out. If your not hardpressed for a system right now, I'd suggest waiting.
As far as overclockability on the K8's is debatable because the memory controller will be integrated, and no one's sure if it can be manipulated.
Well good luck with your new system...

 

Depends on what your using it for. Just using the computer to play MP3's and the internet, won't allow you to get the full benefit of the 1600+ you overclocked.
You'll see the differance in ripping and encoding DVD's, compiling code, and 3D games where there is heavy AI. Most of the new 3D cards out support openGL and DX at the hardware level, where very little graphic rendering is offloaded to the CPU.

Here a screen shot (160 MHzx12.5).....notice how my cpu @ 2 GHz benches faster than a DUAL (SMP) 2 GHz P4 with 512KB L2 cache. You can't compare AMD floating point units (FPU) with Intel's, because Intel's is based on SSE2 while AMD has only licensed SSE1 from them...so it's like comparing apples to oranges. But rest assured AMD has always been stonger in floating point calculations than Intel since the K7. So there is a lot to be had in o/c'ing your CPU, just depends on how you use it.

But anyhow, you have a nice system there...I bet you enjoy the 5 channel surround too! Makes gaming nice!

 

Neah I'm not hardpressed, the ol K6 hasn't let me down since I bought it new. I've got all sorts of odd ball stuff in her including reworking a AT full tower to work with the ATX Gigabyte MB. But the kids will need something to use for school and mine runs what I need, so I'll dream up something for next spring and leave ol Frankie alone. cheers, Bob

 

Shatter it if dropped But seriously, I would worry about solider joints cracking at that extreme temprature. You wouldn't believe how much a metal like steel will shrink when soaked in liquid nitrogen for just a few minutes (around .004").
