My P-s...finally

[tainice]

hi people:

today, I finally gather enough courage to put my P1.26 and my newly arrived XET-C together...guess what? this baby ran at 163 with default, although not very stable, but i am impressed. BTW, i have no idea how my temp doing, the utility provided by GB simply remains constant no matter what..:( any suggestions? damn, i really want to build a water cooling system, so i can run this chippy at god knows how high!! imagine, I have .425 vcore, and 37mhz of fsb to fool around:D oh, the reboot problem still exists.

[muddocktor]

That's a nice overclock, tainice. Now I'll post some results to make you spend more money.:D I now have my 1.26S @ 1700/179 and so far, running stable. This XET board sure is weird though. I'm having to run the PLL setting in normal to do this, which should be o/c'ing the hell out of the pci & agp busses. However, I'm not having any problems with the vid card or any of the pci devices and my usb mouse is still working fine. I'm wondering if this PLL settings kick in automatically after you reach a certain fsb speed when the PLL settings are set to normal.
As far as for system monitoring, d/l motherboard monitor version 5.1.0.4, that is what I'm using to monitor temps. My temps are running at -1° C right now, with Folding@Home running on my machine. That puts a pretty good load on the proc.:D Here is a Sandra cpu arithmetric benchie for you.

[muddocktor]

Here is my cpu multimedia sandra benchmark:

[oldfart]

Glad to have another PIII-S 1.26 XET-C to compare notes with. I must have got a bum chip. I need 1.575 Vcore for a stable 160 FSB. No way can I do 160 FSB @ 1.45.

For temps use MBM5 or Speedfan. Speedfan is cool because it autodetects the CPU sensor.

I also recommend you use Prime95 to test your stability. It really makes it easy to find a problem.

163 2-2-2 5/7 is impressive. That is some very good ram. I have OCZ PC150 with 6ns Hyundai chips and the best it will do 2-2-2 5/7 is 152, which is where I am running now.

[oldfart]

muddocktor, could you post your mem bench also?

[muddocktor]

I haven't run 1 @ 179, but I ran 1 at 175. Now this is with my memory running in asych mode because my crucial stuff can't hack these fsb speeds. It is really taking a beating on the floating point performance.
EDIT: I just ran it with 179 fsb and swtched on isse and I've subbed the new pic.

[oldfart]

Interesting...

My system is a lowly 152 FSB, 1.44 GHz. Your CPU scores kill mine, but my mem bench is ~ double yours. What make more of a difference in real world tests?

I see you have a Ti500. Could you run a few game tests? I was thinking Q3A and 3Dmark2K1 if you have them. It would be interesting to see the diff between:

1.7 GHz, async mem timings. @ 1.7 GHz, you are running a 134 MHz ram speed if I calculate correctly.

1.425 MHz, 150 FSB, 150 mem speed, best ram timing you can run which is probably 3-2-2 5/7

I can't run the 1.7 GHz test (I wish I could).

[muddocktor]

Here's a few game benches: Quake 3, demo 001, default high quality settings, video card @ 240/500 & v synch off:
189.4 frames/sec.
3dmark 2001, default benchmark, video card @ 240/500 & v synch off, 23.11 drivers:
7745
Published at:http://service.madonion.com/servlet/Index?pageid=/orb/projectdetails&projectType=6&projectId=2603389
I tried to make these benchmarks as reproducable as possible, using the default high quality setting in Q3, even though it is only 800X600.

[oldfart]

Darn Tripod. Cant link images. What is a good site to do this from?

[Yodums]

I'm impressed with the new P3-S chips. They seem to be hitting on average 155-160fsb with default vcore with 80-90% stablity. You can always increase the vcore though and some reporting to high 170fsb... mud :)

Here is a shot of mine at 154fsb.

Even though I have had about the same experiences as
olfart with mine, I still like this chip a lot.
I got mine last august, so I have had a lot of time to
play with it. It has been in both my XET-C board, and
now it is back in the Soyo TISU.

I could get it to run a bit faster in the XET, but not much.

I am fairly sure some of these just wont go much above
1500 for some reason or another.... :(

I know it isnt my XET board, got a 1.1a celly running it it now
at 1500 or so, and it's CPU benches beat my P3-s at 154fsb.
(Not by much...)

Since I paid 1/4 as much for the Celly-T, I think these are
the best CPU bang for the buck these days....
Got a bench of that one in that Fastest Home PC thread.

[oldfart]

Never mind. Having a bad day

[oldfart]

OK, try again.

Mem bench

[6502kid]

You get about 50 more points on the mem bench than
I do.

I think that is a fine OC. :D

[oldfart]

I can easily go higher on the overclock. I have my mem @ 2-2-2 5/7 @ 152 FSB. If I go any higher, I have to go to 3-2-2, so I stopped there (for now). My CPU also needs lots of Vcore in the higher FSB ranges. With 152 FSB, I run undervolted @ 1.425 Vcore. Just to get to 160 FSB, I need 1.575. I'd rather keep the mem score up and the temp down.

[6502kid]

Almost exactly like mine, again.

I had to go to 2-3-3 9/7 to get that pic.
Will do 148 at default vcore.

Needs 1.525 for 154. More to go higher quick.
Got an alpha pal for cooler, so I doubt that heat is a problem.

Note. I just ordered an XET with the switches from a link
somebody posted. Hope I get what I want.

May have some more results soon.........:burn:

[muddocktor]

Well, I think that I've found the limit of this chip. I tried 183 fsb and it booted up OK, then Win2K took a kernel dump after about a minute. I now have it set at a nice round number, 180 fsb. I'll try this out for a while and see if it is stable. I have Folding@Home running on it so it will help check my system stability by keeping the proc loaded.

I can see that in the near future I'll probably be getting in touch with Celemine1Gig and get some of that super ram that he can get in Germany.

[RainMaQer]

Just wanted to let you guys know that I now have a puddle of saliva at my feet after reading this thread... many props to you all.:)

[tainice]

people, after i flash the bios, i am not able to run at an aggresive memory timing!!!! so far, with F9, 163fsb, 233, 7/9. bench like 1213/1200, will post more like tomorrow or so. test is due tomorrow.. :( will post the pic tomorrow or saturday. cheers people, i am really having some fun!! oh, my max temp is 35 via cpubrun, and 31 default.

[oldfart]

6502, why the new board? Any switch feature is also available via BIOS settings.

I can go up to 154 FSB default Vcore, then it ramps up pretty quick. To get 6 more MHz FSB is another .125 to 1.575. Very odd. Whats neat is it will run default 1.26 MHz @ 1.225 Vcore.

Muddocktor, that is some awesome work!!

[muddocktor]

It's worked out pretty good so far. I really want to see what those mem benches would be like if I had some ram that would run 180 mhz and 2-2-2 5/7 timings.

[tainice]

my god, i just cannot resist the power of ocing..:D anyway, i just break my own record by working my rig at 42/90(i don't remember the agp, but 42 is for sure). well, guess my harddrive is holding out ok after all those years of beating. tried 183, it boot, but get stock at windows logo. those pll dividers simple give me crap for real, i have to use high vcore to cope with them, and by that, i still cannot tame. well, at least i know my score at 180fsb is like 1264/1300 with 333,7/9 then the whole rig just falling apart.

Doc, you are killing you know? cannot keep up with u so far, got to have some H2O..:p

[muddocktor]

I really think that these boards must automatically kick in the extra dividers at high fsb speeds with a 133 mhz chip because I've never had a hard drive that could run reliably on a 45 mhz pci bus. Also, my M$ optical mouse is still working fine on the usb ports and my experience has been that the usb ports will quit after being subjected to too high an overclock on the fsb. I also ran the Sandra drive benchmark on my hard drive at 179 fsb and it came up with basically the same speed rating as when I benched it on a 133 fsb. I would have expected to see the numbers change one way or the other with a highly overclocked pci bus.

One thing about my rig is it reminds me of my T-bird box in 1 respect; it puts out a lot of heat, running the pelt and cpu on the wc system. It makes a great space heater.:D

[6502kid]

Ol fart. I am keeping the XET-C. I got 2 Tually chips.:D

Will use the new one to replace my Soyo TISU.
It is a good board, but doesnt have as many nifty
OCing options at these XET's do.

Will probably give it to my brother, or maybe sell it to him
cheap.

[oldfart]

Still tweaking.....

Latest setup:

PIII-S 1.26 @ 1.52
160 FSB
1.55 VCore
2-3-3 7/9 ram timing
NO PLL!! (more on that later)

Guys, you didn't get it yet???

I think I'll have to tell you that you don't have bum chips or something like that. You only have to cool your northbridge properly, then speeds above 150 MHz FSB with CL2 are no problem.

That's the only trick!!

I hope it helps some of you! Just cool these freakin northbridge and clock generator chips!

[oldfart]

What do you suggest for northbridge cooling? Mine still has the factory thermal pad. I'm going to replace it with some ASIII that should be here today.

[Celemine1Gig]

The thermal pad, that was used by Gigabyte, is very hard to get off the heatsink!! It's incredibly sticky!! I would prefer to replace the whole heatsink (as I did)!
But using AS3 instead of the thermal pad, would be a good compromise.

[oldfart]

When I get a new mobo, I usually remove the NB HS and put some compound in there. Usually, there is nothing at all. I was impressed that Gigabyte actually had a TIM of some sort. I started to remove it, but like you said, it is really stuck down well! I'll get it off with a Razor, and put some ASIII in there. I'm also going to use it in place of the ASII on my CPU and GPU (GF3). BTW, current setup is:

PIII-S
160 FSB "normal"
1.52 GHz
2-3-2 7/9 ram
1.55 Vcore

Working very well.

[tainice]

just realize i don't know how to post that sandra, help! anyway, i can run my spec at 43/86 no problem so far, very strange. here is my sandra 2002 pro score:

167FSB, 42/84 @1586.97
2-3-2, 7/9 (havn't tried 222 will later)
4372/2128
8642/10729
1238/1254

And another thing, cas2 and 3 do not make a difference in my case, hihger the fsb, better the score, and cas2 or 3 does not matter.

[oldfart]

I've seen that mem timings do make a difference. My mem best case is 152 MHz 2-2-2 5/7. Above that, I have to slow down the timings. I wont clog up the site with a whole group of jpegs, but here are the numbers:

All are 152 FSB, Sandra 2002 mem bench:
2-2-2 1157/1105
2-3-2 1149/1091
3-2-2 1131/1079
3-3-3 1119/1061

What Vcore do you need for 167 FSB?

[oldfart]

160 FSB with pictures:
3-3-3

[oldfart]

160 2-3-2

[tainice]

oldfart:

my bad, after refonfirming with sandra, i notice that the board will automatically reset my mem timing if it cannot handle it, and that'z why i say 222 and 333 make no differents, cuz my board adjusts it to 333. well, now i know that my ram can only do 233-7/9 at 163fsb. At this fsb, needs v1.5 in order to achieve stability.

[oldfart]

2-3-3 7/9 @ 163 FSB is pretty good! My darn CPU needs lots-o-Vcore. I need 1.575 for a stable 160 FSB 2-3-2 7/9. I'm going to mess around with it over the weekend and see If I can get that better.
