PIV 2.4B C-1 Stepping SL6EF Costa Rica

[fxsts]

I went to computer show in Santa Monica in search of C-1 stepping and got one. It's retai PIV 2.4B SL6EF made in Costa Rica and packed on 10/11/2002.

It's booted up at 3Ghz (166Mhz x 18) at default voltage, and it's been running fine since this afternoon.

I will keep you updated how high this thing can go.





If anyone is interested and live near by Santa Monica. It was $193 + $16 tax + $5 entrance free to the show. I saved $7 parking fee by parking my car mall parking on Coloradp and walking to the Civic Center. I got it from guys named Nova Tek Computer.

Did you know it was a C1 when you bought it? Hand picked it by the S-code? Let us know how far you can overclock it

What's your setup btw?

 

[fxsts]

I went there with a list, which I made, showing all the different steppings. First couple of stores didn't even want to bother with me.

The third one told me if I could tell them which one I want, they could look for it, so I gave a guy the list and he found one. I asked him to look for 1.8 and 2.0, but he could not find any.

I am currently running at 3.06Ghz (the magic number, I guess) at 1.600V, editing some Mpeg II files.

I tried at 3.15Ghz, but It was not 100% stable at 1.7V. I use AVC Sunflower with a reduced speed fan (by a volatage controller - I hate noise!!), so it could have been the heat, or it might have needed more voltage. Or, it could have been my Winbond PC3200 DDR400, which has never been very stable at high speed since the day I bought it. My Albatron motherboard does not have the setting to lower memory speed to remove memory as a potential cause.

Are those actual voltages or just what you set it in the bios??? Does the albatron mobo undervolt a bit like every mobo beside the asus mobos???

Still very nice....B0 stepping chips rarely get to 3ghz so this is a nice boost....


Did you look for any 2.26ghz chips???

Duvie,

You are absolutely right. Sandra is indicating the CPU Core Voltage from the Processor Sensor to be 1.55V when it is set at 1.6V in the BIOS.

I did not check 2.26Ghz. In fact, I am not even sure if they had any 2.26 to begin with.


Wait, does this mean this chip was doing 3Ghz at 1.475V? Hmmm, I need to check.

 

[Duvie]

What it tells me is that at 3.06ghz you were running 1.55v actual and that is pretty much about default vcore.....Very nice....

It also means you can likley raise vcore to 1.75v and it should be 1.7v actual and likley get that 3.15ghz stable...I think you are right something else is limiting you as that is a fast wall you hit from needing more vcore to about max levle one should go...usually you can get a 150-200more mhz past the default vcore line...

I'd take that chip!!!!

 

[Duvie]

I am not a big sanra voltage fan...so check it with a good program like mbm and any bios temp reading program that may have been bundled with the mobo...Also when in the bios just look at hardware monitor and see where it is at....

 

[fxsts]

I have been editing mpeg 2 files using TMPGEnc for the last couple of hours, and it seems that the system has been stable so far.

I am going to stay with the setting for now and try higher tomorrow.

 

[THUGSROOK]

nice

I tried a little more this morning. The system rebooted it self at 3150Mhz (175Mhz x 18) while running 3dMark2001 at 1.7V (actual). The CPU fan was still running at reduced speed, so if I had cranked it up to full, it might have completed it. It failed to boot at 3240Mhz (180Mhz x 18). Because I hate to run my system any noisier, I am going to stick with 3060Mhz (170Mhz x 18) at default voltage of 1.525V(actual).

if only there was a way to turn on HT yourself...... that would be one fast cpu, (not that it isn't now), but it would be even faster

 

[dannybin1742]

this really goes to show how much better intel's fab plants are than amds, and how a huge research budget really benefits intel

slightly, OT, I hate noise myself and want to make sure I take care of that for my new system, is that voltage modulator hard to install?
Also what Albatron mobo do you have, a retailer near me has the Albatron PX845PEV Pro and the 2.4b, nice to check the steppnigs!
It seems others have complained that their Albatron was "stuck" around 160mhz FSB. Must have been the CPU ;-)

 

[dannybin1742]

wonder what this would do on watercooling

I am using this fan controller for my system to slow down the CPU fan and cut down the noise. Just to warn you, if you ever get this, DO NOT connect it to the on board 3 pin fan connector. Instead, use 4 pin connector from the power supply. I learned this the hard way and killed the onboard fan connection on my Asus board. Otherwise, it's very easy to install and works great.

I have Albatron PX845PEV Pro, and I am not fully satisfied with it when it comes to it's overclocking ability. I was using Epox 4G4A before that until it died, and the Epox overclocked my 1.6A better than the Albatron. Although it was not 110% stable, the 1.6A could do 2.4Ghz, while it could not even complete booting up Windows with Albatron at that speed.

Given this, if I got some other boards, this 2.4B might be able to do a bit better.

Thanks for the link. Actually that store is just down the road from me and they have good prices on the rest of the components too.
How did you hook the device up to the power supply though, did you have to make a special connector for it?

I'd be happy if I can get a 2.4b up to 3ghz on the Albatron ;-)

 

[Confused]

I've got a P4 2.4B C-1 Stepping sitting in an Asus P4PE downstairs, just moved house this weekend (and only built last weekend) so not had any time to really play, but it's sitting at 2.913 GHz at the mo


Confused

You will need one of these.

nice OC!

 

[BeBumbleBe]

well I picked all the pieces I needed (Albatron, 2.4 C1, DDR, Video Card) but unfortunately I can't get the system to post :-(
Not sure where the faulty component is...or if several are...well have to check that out at the shop tomorrow on their test bench.
I swear I didn't try to overclock ;-)

 

[BeBumbleBe]

Duh...the P4 needs that extra power plug...

Humming along at 2.9ghz/1.7 (actual is 1.6+) totally stable with Prime 95 (that's still THE stability test it seems)
Boots up to 3.1ghz but not stable in Prime95. Mo crashing like with previous CPUs but P95 just stops. Maybe some burning in will help.

It's mind-boggling to go from a 500mhz sytem to a 3ghz system!

My Kingston 2700 doesn't like going up too high though so I've set it to 2x.

I still have an exclamation mark next to the USB Controller. Were you able to get rid of that fxsts? Also there doesn't seem to be a connector for the power led on the board (the one in my case is a "3 hole" one)

Anyway thanks for leading me to this jewel of a chip!

You need to install Intel USB 2.0 Driver to get it to work (and get rid of the yellow '!' mark). If you don't have it, you can download from here or here

It is unusual that the board has 2 pin connection for power LED, but it does indeed. You just need to move the cable pin over to the hole in the middle. You should be able to use a needle to slide it out from the connector assuming that your connector is a regular one.

 

[BeBumbleBe]

Thanks for the tip, took care of that exclamation mark. They're here ftp://download.intel.com/design/motherbd/bt2/USB2.0.exe if anyone needs them.
Wonder why they aren't on the disk, or maybe I missed them.

Right now I'm stable at164mhz FSB or 2.95ghz at 1.75. That seems to be the current limit to run Prime95 without errors.
I'll pick up one of these fan speed adjusters tomorrow although I'm tempter by the Vantec nexus pannel...

 

[Thor86]

Nice OC!

 

[BeBumbleBe]

A brief update.

Hard to get it totally stable above 2.8ghz regardless of the volage. At 2.9ghzm it will run Prime95 for 10+ hours and then halt. Unlike previous generations, though the computer doesn't lock up, Prime95 just generates an error and stops. Maybe it's the Albatron crapping out at 160mhz FSB+

Got that fan speed adjuster and plugged it into the power supply. Even when set to the minimum, it's a subtle difference in sound and I can't see the rpm's to estimate it. At full oad, there 's a HUGE difference in temp though...15+ celsius!

Still a pretty good deal when you see the prices of the 2.8ghz version!
