This is so much fun. There's no way this is prime stable (haven't tried yet), but I can get into XP and manage this with the 4.00B multiplier.

Finally got around to try Orthos Blend and failed in seconds. Bumped vDimm up to 2.0v and lasted just under 4 min. Looks like I need to put more Vcore (and probably MCH Core) to even think about getting anywhere near being able to fully test stabilty @ 2000 MHz. I'm not comfortable with that since modules are only warranted to 2.0v max. Plus, not that much difference in performance to justify possibly fryin them. Hell, I'm still shocked it even booted!

[Triton]

wohoo !

Ofcourse there is a limit in the cheapest DDR2-800 Mem u can buy ! They were never bought to this build, but seemed OK for 4GHz+ with earlier 750i build...anyways:

4150MHz was 8hr+ P95 OK, but later gave error at 5 and 3hr mark...anything above it was a no go, resulting in meaningless tweaking. Had 2x 10hr P95 Blend runs at 4.1GHz (mem 912MHz), and last I could lower vcore to 1.3375v, FSB 1.28(65%ref), NB 1.28v(auto ref) - lower NB and FSB tip by LSDMEASAP

so...I AM happy with 4.1GHz...1.296v load is also helping .....mem is maxxed out...but, should I go DDR-9200/9600? there are OCZ Blades and GSKILL @ 1,8v...I could perhaps get 4.25Ghz with 1.368v bios...but that would be 2.4x mem ratio

Happy or super happy? cost is 100 euros...but G.SKILL are not sold in my country, OCZ Blades arrive in september....

EDIT/// Re evaluate your music! Found Eddie Hazel from '71, rocks Hendrix soxx off -Maggot Brain....all brit gtr players sound this, so does Buckethead in particular. Like it, alooooot

10hr P95 Blend, 4.1Ghz 1.296v load. havent tested lower vcore.

I picked up the GSkill 9600 pi's because I couldnt get the OCZ LV Platinum 1150's to boot at 1200mhz using 240b 5:6 divider. Turns out it was the rev1.1 board that was causing the issue, which I kinda figured after finding the pi's wouldn't boot using 240b either. Out of curiosity I stuck the Plats in the rev1.0 board today and they booted right up at 1200mhz 240b pl8 turbo. Have not tested using Prime Blend but just ran a 32m PI, will test more tonight. In Everest bench they score pretty close to the pi's using higher trfc~54 vs 50 pi's and using 5 5 5 18 timings vs 5 5 5 15 pi's. I am sure the GSkill pi's will clock higher but this was all I wanted. $149.99 down the drain lol.

the OCZ sticks, 1.84v Everest, but what u put in bios?

edit. // u have 800 sticks (cpuz display) running 1200mhz !? explain what they are.

edit // max Bandwidth (6400) number in cpuz must be off. i also see 1150mhz from model number in cpuz.

They are the LV Platinum 1150's, was having issues getting them to boot 1200mhz with the 240b divider. They did 1200mhz 250A 4:5 but that limited me to a 480fsb. This is 1.86v bios.

Some early blend testing at 4.6, ambient is 25C.

Nice job Hoss, great temps for that vcore.

Whatever happened to the fear of 1.4v vcore for the 45nm chips? Seems like you guys are just trying to kill them with voltage now.

The fear was more or less an arbitrary guess when these chips came out. The truth is that a large number of people have been running them over 1.4v since they got the 45nm chip and have had no issues

Especially with the vdroop on this mobo.

According to intels data sheet the max vcore is 1.45.

Nice job Hoss, great temps for that vcore.

Thanks, this chip needs a little more voltage than the 9650 but makes up for it in cooler temps. Even still im ready for some cooler weather, this heat sucks for doing high clocks.

Hi all.,long time not visit this thread.,here my 4Ghz OC last nite.,is it ok guys.,not yet blend or priming.,just quick PI test only..

When is the UD5 supposed to be out?

[Leeghoofd]

I inquired for that to get a sample and they said it ain't gonna happen ( a few months back) as P45 is EOl, main focus is on the P55...

But I hope I'm dead wrong here as it looked like the ultimate P45 mobo

[Hoss331]

I figured that would be the case.

[OC Nub]

That is depressing news for sure. Was excited about trying that board.

[Leeghoofd]

I'll send a mail again tomorrow to recheck for ya guys...

[Hoss331]

Cool, thanks.

Hey guys

Since i messed with bios F10e i corrupted my raid...now that F10e is the backup bios, how can i put my actual F10b on the backup bios ?

Thank you

Cheers

Could it be them OCZ stick are Samsung based Bluestang ? I can't even get 1600mhz stable with the microns Low voltage rams for I7 work fine...

Don't know Leeghoofd, I wan't to pull the heat spreaders off to find out, but I'm afraid of yanking off a chip too! Since they are not mine (this is a work pc) I'm a little hesitant....any recommendations on how to easily accomplish it?

BTW, I'd love to see some settings (volts and refs) you used on the "Pentium E6300 and Battle of the Caches revisited" 8x500fsb runs

Question guys....I'm running Orthos trying to find my magic numbers for stability. I keep passing large ffts, but hit the small ones about 17 min. in and fail. Any ideas what this indicates?

[Don_Dan]

If I'm not mistaken large FFTs stress the memory subsystem while small ones stress the CPU the most and thus create the biggest heatload.
I think you should look at your CPU temperature!
