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.

[dnottis]

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.

Nice job Hoss, great temps for that vcore.

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

[OC Nub]

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

[Hoss331]

they said it ain't gonna happen ( a few months back) as P45 is EOl, main focus is on the P55...

I figured that would be the case.

[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
Sergio

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!

[Leeghoofd]

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!

Speed fan shows 61 core 59 core 1&2
I'm still trying to figure out Gtlr %

[tool_462]

Working on 4Ghz 24/7 stable with good memory bandwidth and am having a little trouble. Currently on a Q9550 with G.Skill Pi Black DDR2-900 (8GB installed) and a GTX 275.

My settings are very close to stable, OCCT errored out after 3 hours 4 minutes one time and then after over 4 hours the next. IBT passes on standard settings each time, but I want to cure the OCCT error.

Any suggestions? This chip is taking more vcore than I'd have guessed based on the batch (L847C219) for 4Ghz, so any ideas to get that lower will be great

After I get this profile 100% stable I'll go to work on 8 x 500 CAS 5, or until I get some OCZ LV or Gskill 9600's

I'm also curious about vcore on this board. It seems I can adjust it up or down 2 settings without the loaded vcore even changing as read in CPU-Z/Everest. Even if CPU-Z doesn't detect a change, does the board actually give the chip slightly more voltage? I ask because I don't have a DMM worthy of measuring a voltage change that small.

Id drop both your cpu and mch skews back to 0ps first.
