So LoD-tweaking is forbidden?

Lod is allowed, mipmap tweak is forbidden

LOD is a valid tweak, it can be done through drivers control panel; or rivatuner, so it's accepted.

Mipmap changes the way image maps are rendered and drastically changes the outcome, visually and score wise;

When did you change lod the last time ? Changes image also very drastically

when did you disable mipmaps the last time? ;)
world of difference

Let's get it started :D
SuperPi 1M: 10.219
E8600 @ 4550MHz
http://www.hwbot.org/result.do?resultId=856170

3DMark01: 76803
GTX 285 @ Stock: 648-1242-1476
E8600 @ 4400MHz
http://www.hwbot.org/result.do?resultId=856169

Just to set some starting points :p

I had my FSB at 500MHz (multi 9, so 4500MHz CPU), so that's not the problem: it seems the CPU can't get much further. Now running at 1.44375V. What's a reasonable maximum voltage for air-cooling?

I'm having quite some troubles with 3DMark, especially the high-test (CH, DH, LH). I'm getting hiccups and artifacts, even when running on stock speed :(

Lol, forgot all about this contest. Don't have a 1M score just yet and I'll probably not submit one since I have little time available.

Benelux finals are in June, so no time then either.

Power if you want ot have the phase come over (Erpe mere) and use my voltmodded 285 mate, 745GPU /1700 shaders/1450 rams on air (no hicups there :p)

3DMARK01: 95150 - http://service.futuremark.com/compare?2k1=9497254 - http://hwbot.org/result.do?resultId=856180

Thanks, but I've got a vapochill standing here. I start on air, and will take the vapo for some better results if the competition asks for it :p
Just ran 700 - 1594 - 1350 (unmodded), now taking out the card and conductive ink ;)

trut :p

not ink mate use the volt mod I showed ya ( these cards are all shader limited ) sometimes it's better to run unlink and keep the shader at max 1697 (voltmodded)


+1 TRUT (9600GT lol)

:p

I might hook up the E8600 to the Mach2 to have at least 1 score, but it won't be spectacularly high

I'm going to do the mod you linked before:
So I need the conductive ink, no?

What cooling?

On Phase this was the max for this CPU, 5.7Ghz was BSOD etc

Geoffrey soldered me 285 ( the wizard )

Ik volg even niet :p
Je geeft me een link om een 260/280/285 te modden, met conductive ink om Vmem en Vgpu te verhogen. Da's hetzelfde als die bruggen dicht te solderen, maar ik vind geleidende inkt makkelijker werken...
Maar wat bedoel je dan met "not ink mate use the volt mod I showed ya"?

Er zijn er een paar die inkt gebruikt hebben en hopen probs hadden erna. Ik heb dadelijk het zekere voort onzekere genomen en Geoffrey gevraagd om te kaart te modden

Was able to do a few quick 1M runs under Mach2 this evening, here's my first run:

8.25 - E8600 @ 5.5G - http://hwbot.org/result.do?resultId=856718

I've put my E8600 under my Vapochill LS. It can do 5350MHz even SuperPi 32M stable, but can't do 5450MHz SuperPi 1M :(
I tried changing the RAM-timings from 4-4-4-12 to 5-5-5-15, setting performance level to Standard in stead of Turbo, higher Vcore, higher Vmem, higher Vmch, but I still can't get over that 545MHz FSB.

My settings are:


Any ideas?

is that UD3P ? Lower MCH voltage ( very heat sensitive) and mess with the reference voltage and check via memtest ( test 5 and 7 ) before entering windows

Some CPU's just need masses of FSB term voltage, but my bet is on the Nb , more isn't always better...

It's the EP45-Extreme with a huge heatsink on it. Does that mean it couldn't be the heat (so the Vmch)?

FSB term voltage = CPU termination?

Try to play with the MCH reference voltage eg 0.74 or so and memtest ya rig before entering windows ( a few passes of test 7 will determine if it will survive Pi or not )

FSB = CPU Term...

Which CPU Skew and NB Skew ?
Does that ram really need 2.48 ?
Are you runing sync or not ?
Which PL selected ?

With fine tweaking 580-590FSB on air should be doable... not with 10 multi ofcourse :p

George did a good review on it :

ep45-extreme

Trying to answer these questions although the system is powered down now:

I try booting into windows at 520-530 now, and using the EasyTune tool I can run SPi 1M at each step of the FSB. Memtest might indeed give me a stability-test, but do I need that? If it's SPi 1M-stable it's okay...

CPU and NB-skew: 100ps
The RAM-voltage is that high in that screnshot as I was testing if that was holding me back. Now it's at 2.4V. It's cooled very wel (2x120mm) and has D9GMH or D9GKX-chips on it. EPP-profile shows 2.2V and other manufacturers have those chips with an EPP of 2.4V...
What do you mean with sync or not? Mem-divider is 2.00B (B = 333MHz-strap)
Performance Level is at the middle of the three options. If the options are standard-turbo-extreme, it's at turbo. But I don't know the name of the setting by heart.

Considering all those questions and no more comment on the Vmch: can I conclude 1.4V with the massive heatsink is okay?

I hope to do 580-590FSB :D

One of the big differences is:
My clock drives are at 800mV and skews at 100ps. Do those settings make a big difference?
Besides: there's quite a difference between what you set in the BIOS and what's shown in the easytune-utility. I read that a lot on forums, but I don't know what voltages exactly differ...

First, try to figure out what's the maximum FSB with a lower multiplier. If it's higher than 545, you know the cpu is holding you back.

On air (with a lower multiplier) I couldn't get over 545 either. But I will try with the suggestions leeghoofd made...

Try CPU at 200 and NB at 100 Skew ( never the same )

Memtesting with test 7, if it passes you can bench for sure at them speeds ( Pi and 3dmarks without an issue)

Ram PL is TRD in the Giga bios ( I believe ) Leave CPU and PCI Clock drive at AUTO (didn't need to move that setting at 580FSB Hyperpi stable)

Easytune readout is borked , there was a workaround but I never tried it, I'm a boot from bios guy , I loath windows utils...

580FSB shouldn't pose a prob



This is with the EP45T UD3P (DDR3 version)

1M quicly done on i7 and cascade.

I think 5.6 1M is doable under cascade ...

I wonder what it can do on LN².
Hope there isn't a coldbug.

Core i7 has a coldbug...

It is maybe between -120 and -140° :D

Kick *** Thomas in Taipei !! And plz keep an eye on Massman...

lol should we lose him what then ??? :D.

kent ge het gezegde : je bent wild en je jongt wat, ik wil gewoon massman tegen zen eigen beschermen :p Nooit de poes bij de melk zetten :)

is da nie je bent jong en je wilt wat :p.

Higher scores :)

SuperPi 1M: 8.454
E8600 @ 5550MHz

3DMark01: 99423
GTX 285 @ Stock: 775-1475-1596
E8600 @ 5310MHz
http://www.hwbot.org/result.do?resultId=859356

Lowering the multiplier, I had a FSB up to 570MHz, couln't get higher. Check http://valid.canardpc.com/show_oc.php?id=577737
Raised the multi back to 10x, but even at 1.8V, the CPU can't get over 5.55GHz SPi1M-stable, and I have tried about every setting :/

Nice score mate. No way you can get it over 550FSB with a lower multi ( tried memtesting it ? )

Ya card clocks awesome :p very nice (pencil mod ?)

I have reached FSB of 570MHz with that lower multiplier. I didn't try memtest, as the main purpose is to have it SuperPi 1M-stable...
My settings: http://www.johanlemaire.be/OC/E8600/...20Settings.JPG
Generally, these readouts are the same as set in the BIOS, except the CPU Ref, CPU Ref2 and MCH Ref. I had those at 0.78, 0.836 and 0.796 respectively in the BIOS. But I tried lower and higher values, to no avail :(

Yes, pencilmod. But if I raise the shaderclock too much, I have to keep lower gpu and memory-clocks, with lower performance.

Which Pl is that on Johan ?

I would give 1.36NB voltage, MCH reference around 0.74 a shot, works fine on my EP45 UD3P till 580FSB... I have noticed on the Rampage extreme if I can\'t pass that memtest 7 test, that 3druns would be pretty hard to do... P45 remains a very sensitive chipset regarding volts...

Here\'s the run we did with Blind for the GOOC qualifiers

[IMG]http://s3.photobucket.com/albums/y90/blind_ripper/?action=view&current=Clipboard02.jpg[/IMG]

I had issues with benching 3D over 5.6Ghz due to heat, maybe that\'s ya issue too
