Look for settings working with Asus P5KC and DDR3 Gskill

[Touch67]

Hello,

First sorry for my english !

I am disappointesd my Gskill ram doesn't work well at 1333 Mhz with my Asus P5KC motherboard.
I asked for any solution in Asus forum :

Hello,
I read several topics with great interest cause I know same problems.
I set 2x2go DDR3 1333 mhz RAM on my P5KC, but does not work stable.
I tried everything said here without result. Nothing work except set RAM on 1066 mhz in Bios.

My PC :
Power Unit 600 W
P5KC bios 1203
Intel Core 2 duo E8400
2x2 Go RAM G Skill Extreme 8-8-8-21 voltage 1.6
Windows XP pro 32 bits

I tried all combinations with DRAM frequency set on 1333 :
All others settings auto
Manual settings
Manual DRAM voltage
Lock FSB coefficient to 9 x 333 or auto setting
More CPU voltage or auto setting
etc...
Always ends to crash in few minutes, sometimes with blue screen : the best I had is with all settings auto but DRAM lock on 1333 mhz. Works ok on idle but very instable while playing or even with internet navigator (IE or Firefox) : freezes and then crashes...

Only solution that works fine is setting DRAM on 1066 mhz : then works very stable, able to stand OCCT during one hour.

Any solution ?

The only answer I received was to try set manually all tweaks...
I did not succed. I am very suspicious of an Asus problem, not able to delivery a correct bios nor correct answer.

I read many posts relating same problems ; that one is synthetic :

Dear friend, I see here a lot of people have the same problem I had some months ago with an OCZ set of DDR3 1333 memory. The set was not stable at all and I got lost into the labyrinth of internet requests, settings and experiments. Actually the solution was simple thus frustrating. The only QVL (approved by vendor in other words) approved memory I could find was corsair DDR3 1333 which actually had a proof of test scanned for internet use. I don't remember where I got the proof from (just google it e.g. p5kc TWIN3X2048 ddr3 test) but with a print of that and the url underneath this I took them back to the shop I bought them. I was annoyed and disturbed by the attitude, but they finally replaced them with the ones I mentioned above.
All my problems are solved now. Ok some here claim that there exist some settings that will make the memory work. I have never seen one here claiming that they did work! my OCZs didn't for what I can tell, who knows about the rest.

I hope I helped. I had a horrible time trying to make the OCZs run, and finally failed.
OCZ offered a refund, but that would not solve the problem.

Regards

Right now, my PC runs stable with 1066 Mhz... a bit frustrating

Have you any idea of any solution ?

What CPU are you running and could you post your current BIOS settings.

Hello,

My PC :
Power Unit 600 W
P5KC bios 1203
Intel Core 2 duo E8400
2x2 Go RAM G Skill Extreme 8-8-8-21 voltage 1.6
Windows XP pro 32 bits

My current Bios settings are "all auto" except for RAM frequency I downclocked at 1066 Mhz, that was the only way to work stable.

I tried "all auto"(RAM 1333) but failed... Tried others manual settings too but never found the one that goes well at 1333 Mhz.

tRFC needs to be 127 or 127.5 depending on the available option, also don't use AUTO for the base timings (8-8-8-23) enter them manually as well as the command rate/timing at 2N, the DRAM Voltage 1.6.

[Touch67]

Ok I try this and report later, thx.

[Touch67]

Ok I set values :
8-8-8-23
TRFC can't be set higher than 110 (max value available in Bios)
rate 2N
Voltage : if 1.6 can't run : boots, starts windows and then crashs immediatly with blue screen, or doesn't even start windows after post message.
Voltage : if auto, it runs : the PC seems very much faster, but is not very stable : explorer fails when use it...
Make some tries with 3D games and tell you.

[Touch67]

Ok, I had a hope, but it does'nt work...
Blue screens, ieexplorer failures, auto reboot... back to 1066 Mhz and full auto

Mate, I have the exact same problem, been having it for over a year.
I noticed though, that I can at least set the timings manually and it's stable, but for 1066 (7-7-7-20), not anything higher.

My board: P5KC
My CPU: Q6600
My RAM: 2x 2GB DDR3 Corsair 1333 9-9-9-24, 1.7V

Will NOT run stable at 1333, no matter what. It is very weird, since this guy got it to work (read the last post on the page) http://www.ocztechnologyforum.com/fo...KC-DDR3-issues

I also tried his settings but no luck.
No matter what i do (tested individual sticks too), how ever i set them to over 1066 Mhz, I get a "Page Fault in nonpaged area" bluescreen ("STOP: 0x00000050"), at least that's what I got last few times i remember.

Thing is, it doesn't happen in full load. I get the bluescreen after around 3 hours of uptime, regardless if the computer was idle the whole time, or running Memtest, or Prime95 or playing games or browsing the internet.

On 1066Mhz it never crashed. This sucks since i was really planning on getting my cpu to at least 3Ghz but i can't do that without OC-ing the ram aswell.
