Hi guys, in usual ocuk fashion my purchase came in record time and man what a quality piece of kit, the packing and little nifty bits = awesome

I am having an issue though and is that I cannot POST at 1000MHz! I have an Asus P5KC and have tried manually assigning the timings and voltage (2.1v) and nothing - PC powers up but no POST, rebooting takes me to the BIOS setup prompt for settings that are out of parameters.

Looking in CPU-Z with the ram booted at the moment at 880MHz I notice 1000MHz is tagged under "EPP" mode - anyone have any idea!

Cheers

I'm not sure what you mean by high divider as there's no option to manually adjust the divider from what I've seen in the BIOS !

At the moment I'm at FSB:RAM ratio of 4:5 if that helps and that was auto set after I chose the Ram clock speed :/

Bleh no luck at all getting above 900mhz :/ I'm beginning to think it's an issue with compatibility with the P5K-C.

I've requested a return from OCUK via webnote as there's little else I can do now, I'll just get a pair of DDR3 1333 when they drop in price next and settle for that.

I've taken it out now and put the corsair back in but as it stands:

No option for tRFC ? :S

I've decided to keep the ram anyway though as it runs fine at 900mhz, i'll have to play around to see if I can get 1000mhz but at 900 I get almost 500more 3dmarks so...uhm....I guess it's all good in this regards ^_^

Ooh that reminds me, I need to go buy some floppy disks!

Flash from the BIOS using a USB key

I actually tried this, from USB card, cdrom, dvd etc as my BIOS has EZ FLash but I think the old BIOS I had did not support flashing on newer BIOS files with the built in utility so I just had to drive to town, buy a floppy dirve and disk then install caldera DOS to boot with floppy and flash using AFUDOS.

Mega faffing around needed but OH MAN! I AM NOW RUNNING MY RAM AT 1000MHZ!!!!

Excuse the Vista Basic theme, I'm reinstalling VGA drivers as the BIOS update knocked them out!

Nice one, glad you got it sorted

As for bios flashing using a USB, I use (the freely downloadable) Ultimate Boot CD to boot into DOS mode, then flash from my USB drive, works great.

:O do you have a link mate ? I also find I get better benches runnign at DDR933 with CPU @ 3.15GHz compared to 3GHz and DDR1000 as I cannot get my cpu stable above 333fsb with ram at 1000 - no biggy though as both perform excellent

Ok RAM is at 978MHz now, took the CPU to 367FSB to give 3.3GHz - I could not get 3.2GHz before the BIOS flash and I guess a combo of new BIOS and better RAM means I can - awesome stuff!

Reckon it would be better with CL4 timings at slower MHz? I always thought more Mhz = better!

mrk · 6 Mar 2008 at 22:15

Ah I see

My P5KC reads anything with FAT or standard CD file system, even my USB card reader is visible by EZFlash in the Bios if I put the BIOS on a 1GB CF card
