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!

Mine is currently running 500MHz (cpu is 400x9) with 5-5-5-15 timings. Boots fine and primed for over an hour without issue (although small ffts so a cpu test really - shows its semi stable at minimum :p)

I've also got the SPD Ext thing showing, can't say I've ever seen it before.


Imagine this is a really stupid question, and quite likely patronising, but you are trying to boot up with the ram on a high divider, not with fsb straight off? :/
I really can't think of any other reason for it not to be posting.
 
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 ^_^
 
Odd one, ran 1000Mhz on auto on my P5K-E, didn't have to select any timings.

You got the latest bios for your mobo?

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 :)
 
hmmm my motherboard is telling me its PC6400 as well, however i can get it to its stock speeds perfectly fine. might just be CPU-z needing a update?
 
I just flashed my BIOS from within the BIOS itself. Had the BIOS file on my USB stick and pointed the BIOS to the file and it flashed perfectly.

No buggering around with DOS disks or Windows :)
 
Might try flashing mine from bios. Hopefully I won't kill the second p5k-e of the week :p
(killed on on thursday flashing from windows :/)

Couldn't do that on mine, BIOS wouldn't see my USB stick.
