Bmarks for 2400+

[markodude]

Has anyone done the oc.com seti benchmark using this processor yet?
It appears the fastest Athlon is Hallen with his 2200+ at 1993mhz and 209mhz memory bandwidth. I hope to get the top spot by the end of the week using my 8k3a and 2400+ (comes tomorrow definetely woohoo), at maybe 200x12 or 190x12.5 for 2.4ish ghz. What sort of WU time do you think I will be able to get??
I hope the extra FSB doesnt make a major difference as 206 is the highest Ive got and I dont even know if its prime stable yet, 190 is the highest Ive tested as Prime Stable. It is PC2100 after all (see this thread (http://forum.oc-forums.com/vb/showthread.php?s=&threadid=134492)
Cheers peeps

Try the 2400+ with your Corsair XMS3000. You should be able to use more agressive memory settings.

Samsung PC2700 will do almost as well if these people are still selling the CTL:

Still, your Crucial is a nice stick and should easily do 2:20.

Are you really doing a 30 X Cluster?

Good luck with the new cpu.

hehe the man himself - glad your up for a bit of sporting contest although its not really fair as I have a 2400+!, as you say the mem timings could be better so I may nick a stick of XMS3000c2 out of the work rig as its way under its limit in there...
I was considering a 30PC cluster, using the PC's I run as network manager at our school. 30 P4 1.5ghz SDRAM based (s478 with Aopen mobo)
However it seems a lot of hassle for little gain, I mean the fact that it would be a cluster doesnt seem to gain much time wise and setting up a linux cluster server etc seems to be difficult.
I am probably just gonna put seti driver on them all using a logon specifically for it and running them at nights and weekends. It will still increase my daily w00tage no end!
Ill keep you up to date with the 2400+ adventures tomorrow...

Acording to the calculator in SETISpy (you can access it from the Performance/Compare/Calculator) using an old Tbred with 256Kb of L2 with 200*12, DDR you'll be getting 2 hours and 23 minutes for a 0.417 AR WU.....

Let us hear what you get with this new baby :D

Its always worth it for more WUs. You could set it up as a service so that SETI is always running even if no one is logged on. My brother has a dell 1.6 w/SDram and it avgs 5h a WU.

The benefit of clustering for Seti is building cheap machines. If you already have full blown systems there's not much point. Just install Seti as a service on each one.

[markodude]

Can I install SETI as a service on a win98 station? How would I go about doing that, and do you mean the CLI or the Graphical version?
My initial plan was just to create a logon specifically for seti, I cant affect the users processing power too much or have any icons that they can see/muck about with....
I have put a folder called C:\seti on each station with seti driver, the cli, and set it up for a 5 WU cache on auto transmit, then I just need to make a logon called seti and put Seti driver in the startup folder....although perhaps installing as a service is a better way, as it wouldnt have to be logged on..
Any advice much appreciated.

2400+ just arrived, testing in about 9 hours time, cant wait to get home from work now!

Sweet!

Bench that baby- and as far as Seti performance goes, FSB definitely rules. High as you can run it without staibility troubles my friend.

Back when still had our XP's running slow :D and I broke the 3 hour mark, my rig was a couple hundred mhz SLOWER than the other ones involved in that little race- but I had the fastest FSB in the "competition."

Of course, I have been thoroughly trounced since then:D:D
But there is the evidence.

I have a link somewhere to info about running as a service under 98 but I'm off to work now- I'll check tonight and if its not posted I'll see if I can dig it up.

[markodude]

Cheers mate, it does seem that FSB is king on Seti, rather than pure processing mhz...
Hehe its all in fun anyway I am just happy to be one of the first in the UK with this chip and it will be cool to have the top Athlon in SETI league for a little while, until someone gets a better overclocked 2400+, or a 2600+ :D

[lonewolf1983]

yep you will want to boost that fsb and drop your memory timings to get that top XP spot....
although outright speed is good, memory bandwidth and fsb is king with seti

Marko- If I remember correctly the Four Horsemen ran Seti off a network drive when they had access to their Lab computers.

Slows down the wu processing but keeps users from messing around with your Seti folders.

XP2400+ sounds good so far. It will be nice to see how much improvement TBredB is over TBredA.

[Sir-Epix]

yeah and we had it tied to a setiqueue. It was all hidden, and the user had no control over it. Let alone know it was running.

[hallen]

Hi teammate- Those were the good old days with 500 wu dumps at midnight. :D

Have you seen the Seti Home page today?

Halloween at Arecibo: Two of SETI@home's scientists will be at Arecibo over Halloween to discuss the implementation of multibeam detection (observing multiple locations of the sky simultaneously).



Nice topic if they could do a web broadcast.

Harvey

Is that picture correct? Are the L1 bridges uncut?

[markodude]

Yes it is correct, thats my chip and it is unlocked as standard, you have to bridge 5th L3 to enable all the low multipliers under 12.5 I think, I did it straight away.
Anyway not having much joy OCing it, these TbredB cores seem to run extremely hot, I mean at the moment I am running 190x11 for 2100mhz, but it needs 1.7v, and its only a 40mhz overclock! Ive seen 57c in Prime95, about 55c on SETI. I tried 190x11.5 and got an error in Prime95 after about 3 iterations, that was with 1.825vCore, and hitting 60c.....this baby idles at over 40c!
So my initial hour or so of testing hasnt produced the results I anticipated. I reckon you need water or phase change to overclock these babies well.....
Im benching it at 190x11 just now. Will post results at lunchtime or tonight when I get home.

[hallen]

Marko- This is a 2200+ with a Thermalright AX-7 and Vantec Tornado.

The benchmark was 209 x 9.5 = 1993 but for 24/7 with my back turned I dropped down to 193 x 10.0 = 1930. I can't afford those -0- wu nights.

Long term 1.85v hasn't affected the processor.

Harvey

edit: Have you tried a case fan pointed at the HSF? That usually brings things down.

[Greg M]

I read the B's actually ran cooler. Is something else wrong, or am I misinformed?

[Sir-Epix]

I am hoping those days will return next semester when all the lab computers get an upgrade of more Ram and WinXP. XP being the most important upgrade.

[markodude]

Hmmmm I would have been as well getting a 2200+ for all the extra mhz the 2400+ offers! Im going home now to see what time I got on the ocsetiteam benchie and try and overclock a bit more...
Speak soon

[Just shoot]

MARKO, The 8k3a has some funny settings that need to be changed depending to get the bandwidth to get close to the board that hallen has at that front side bus. I found with my 8k3a that my times were actually considerably slower with the front side bus cranked up around the 200 relaxed timings than with 182 with the timings set to normal and then change timings manuall but leave the intial setting to normal. This will give about 5-6 MHZ more OC with the aggressive settings.
Also make sure that you have a bios with the fast cpu code enabled makes a big difference as well but limits the FSB. If you head over to AOAforums there are a number of register hacks that increase bandwidth with a total of 75 to 150 more points in sandra. I personally use the 2815 bios and think its about the fastest with some of the registers hacks. I would say which registers to change but its going to depend alot on your hardware and how far you can push it. I've had two of these boards both refurbs and register changes on one board that made a big difference didn't really help the other which I don't really understand, alot of trial and error was needed.

At your present speed of 190X11 it should be killer. My kingmax memory gets flakey above 182 max timings and 3.2 volts :D. Good luck and I'm, as others, curious to see just what it will do. That way I as welll will no were I need to be to get the TOP XP spot back.

P.S. I've run both a xp1600 and a xp2000 at 2.2 volts water cooled 182x11 for months now without a problem. xp1600 temps are 48'C and xp2000 at 49'C using internal probe of the 8k3a

Hello people,
Im a bit happier today, ran the bmark at 190x11.5 and got 2.50 hours, pretty good but not as good as I had hoped for!
Im in a bit of a mess with regard to my system though, my temps are still well high using the CPU diode to monitor, Im at 1.85v now - with some extra fans Ive got full load to 55c, but thats still a bit high for my liking.
My 8k3a is doing funny things with the multipliers, I cant even get the stock 15.5x133 to work as 15x is the highest multi in my bios. If I select the follwing I get weird results.
x12 and lower = x12 and lower
x13=x13.5
x14=x5
x15=x5.5
I need to check what bios I am running but was sure I flashed the latest one...perhaps I havent!

[markodude]

Just found out the 2400+ is actually 2.00ghz, the site I got from had it advertised as 2.06ghz which is 2600+, makes me feel a bit better about my overclock...
Landshark, whens the next update on your site? I wanna see my 2400+ on there :D

[markodude]

Managed to drop to 2:43 now! 175FSB but Cas2 memory and all settings at Turbo, 12.5multi for 2.2ghz....

[hallen]

Nice work and congratulations on the benchmark.

With a burn in and maybe a KT333 board there is no telling how much more is left in your cpu.:D
