E6400 Super Pi Thread

[ANP !!!]

How r the 27A week CPUs. I have one, n will be benching soonnn .

[Valmont]

Hi,
@ANP, English is not my native language either and I'm new here. For my first post, here is mine :

My new superpi score





Have someone tips to get sub 15sec ? I saw a lot of guys with only 3800mhz getting sub 15..

I have tryed to boot in diagnotisch mode and have adjust maxmem from 100-800 but no different.

[.devastatioN]

All stock voltages exept for ram which needed 1.9v
If I go anything higher it gives errors on orthos...

Week 27 CPU

I might try some more but I have bad IHS. Im using AF7PRO and temps on cores are 50C stressed at dual prime @3ghz... I've seen much better temps

I've already tried some more but I want to stay close to stock as much as possible. 3.2ghz didnt want to boot OS, no clue why.

Zalman 7700 cu + P5B Deluxe

[ANP !!!]

Nice clocks n Results guys..

[serialk11r]

My gay motherboard (asus p5n32sli se deluxe) stopped at 300mhz fsb... nothing will get it higher I got 24 seconds 1M!!! WOO HOO! Just an hour ago, my board decided to break down further, and I'm stuck with stock speeds...

[aasmaukr]

My E6400 is bad. L628A. I ran 1M at 3704 with 1.5v vcore in BIOS (P5B Deluxe) with Mini Typhoon air cooler and lapped IHS. I didn't really gain anything with the IHS lapping and higher vcore doesn't help OCing. I tried with 6x multi and my board stops at 500MHz FSB.

You don't even need 3800 Mhz to get sub 15s SuperPi 1M 3735 Mhz on E6400 is enough

Platform:

E6400 630A448 @ 1.59V
Thermaltake Sonic Tower
Asus P5B Deluxe Wifi-AP unmodded
2x1 Gb Corsair 6400C3 @ 2.45 Vdimm
8800GTX
PCP&C 850W

I'm by no means the ultimate Pi tweaker, but:



The key here is to stay on 1066 strap ( = boot @ 400fsb and clockgen up - this offsets at least 100 mhz of raw cpu speed). And the other Pi tweaks, like closing explorer, and so on.

My cpu can do 1M at least to 3850 Mhz on air, and mem is capable almost on DDR2-1200 4-4-4-8, so it is clear the board is crapping out in my case here... so more Vmch (remember, here the board is unmodded) would probably bring me some more Pi goodness for sure

You sure it wonh't go any higher? What's your temp?

[aasmaukr]

Yup.. I'm pretty sure that's where it stops. I tried a couple different BIOSes and played a bit with voltages and mem timings. Btw, my mem does 525MHz 1M with 4-4-4-10 timings and 2,45v (in BIOS) so that's not what's stopping me.

I'll test with another P5B-Dlx and I'll also see how it likes better cooling (SS).

[The_Hardstylez]

Thanks for the tip mrlobber I got my new board today ( p5b dlx).

I'am gonna try it.

[ANP !!!]

here are mine..

tomorrow will try to play with the timings, btw can some1 tell me, why soo high time for the speed. I mean i m pretty sure i should be getting much lower time for a 3.95g .

can some1 give me some tips..

[sub_zer0]

has anybody had much luck oc the e6400 L630A?

mine seems to be maxing out at 3.2ghz with 1.525v. the fsb doesnt want to go over 400.

[Norz]

Sub 15 with a E6300 is possible .....
...if you got a desent mobo and ram,no mods only watercooled
L627A B2

[Bootup05]

I get 16 seconds over here at 3.62/3/4/5GHz

[krompirusa]

4.1ghz super pi.Supertalent ddr2 800@1026 5-5-5-18,P5B-DELUXE,scythe infinity,.....I need some micron d9, to go higher .Windows xp pro sp2, with no tweaks.

[funkflix]

My old E6400, just had the CPU a few days and at that time i didn't know that "better" timings are slower on P5B..



Primestable 3600MHz 1,43V.

[Drager2]

And here is my:

14.515sec
E6400 L630A406 B2 @ 4043MHz 1.7v under chiller +13 | Full unmoded Asus P5B Dlx | Geil PC8500 Plus @ 1011MHz 4-4-4-12 2.45v
So is it good? I think that I should have highes score...

[JMKS]

You need some tweaks (both hardware and software), guys .
I have sub-14s @ 4117MHz, with everything I know (and I'm not an ultimate Pi tweaker, believe me ) tweaked properly, so 4+GHz and ~14,5s is not the best reachable , keep tweaking and trying .

[krompirusa]

JMKS look at mi timings its 5-5-5-18.When i get ram to go 4-4-4-8@1000+ im going to score sub 14s.

[tiborrr]

Krompirusa, tighter timings don't add up (that) much on C2D.

[dinos22]

JMKS look at mi timings its 5-5-5-18.When i get ram to go 4-4-4-8@1000+ im going to score sub 14s.

tiborrr is right....there's no chance you will be able to shave THAT much off the times with 4-4-4-x....even if you had a 975x board and 3-3-3-x i don't think you'd be able to do sub-14 relative to your current times..........it is possible as the polish guy showed but you need to work on tweaking more too + get a 2GB kit of RAM...that will help in times too

[Drager2]

JMKS As for my result: IMHO you aren`t right... You have +1Gb Ram /+75MHz CPU /15MHz Ram freq = I think it could made 0.5sec.

I need to take a screenshot when I do SPi runs, I was just doing them for stability testing and broke into 13.8x with 4200MHz. System isn't stable after 4200MHz which is weird, I can bench 3D at 4200 and I can do 32M at 4200 but 4208 causes a crash, I think that might be the limit of my chip and/or memory. I wish I knew more tweaks for SPi, wish one of the masters would tell us everything
