It's hard to find them in Belgium too. They are imported from Germany.Quote:

A good computer parts dealer can get there hands on everything.
My Swifftech watercooling kit that I've bought is also imported. The computer parts dealer, where I order my computer parts, imported it from America.
That explains everything.Quote:

depends on bugcheck hex code, more likely it's from incorrect GTL's and clock jitter destabilizing the set GTLs.Quote:

Didn't have time to test it more, only did linx once - so it doesn't have to be LLC fault. Anyway I'm still testing and from what I see disabling DRAM Static Read Delay and setting both skews to normal [not auto] is giving me now full stability in MemScope.Quote:

Could you tell me exacly what I have to do? Have no freaking idea about what are you talking. :DQuote:

Right now with the BIOS that we have it is probably not possible to have them running stable at 1200MHz. You can try to adjust some settings or timings to get them to run at 1200MHz but I don't think that the problem is situated there. With the tests that I've been running at +1200MHz and the strange random stability problems in Prime95, I can only come to one conclusion and that is that some adjustments needs to be done by ASUS in the BIOS.
I hope that I'm right about that and that it can be fixed in a new BIOS release and that it isn't a problem with the motherboards hardware.
Some guy at the ASUS Rampage Formula forum has the same problem with his 4 X 1 Giga OCZ Reaper HPC PC2-9600 Memory. He can't get them to run at 1200MHz. He tried everything, adjusting voltage, adjusting memory timings and adjusting skews. Nothing helped to get his memory running at 1200MHz and he gave up trying and hopes that a new BIOS release can fix his problem.
All we can do now is wait and hope that ASUS won't let us down and fixes the problem.
If it's really a memory problems shouldn't you have BSOD's on load too?:confused:Quote:

Right now I'm using that MemScope which mikeyakame posted link to.Quote:

But after 6th loop I've got 2 errors what tells me to think that its MEM related problem not the LLC problem since I'm getting errors under load.
You probably right but I still don't understand how someone with the same BIOS settings is able to run stable with LLC Enabled and someone else has problems with that.Quote:

I was actually running stable afterwards with LLC Enabled for more than five minutes.:up: This was my personal record.:D
Try higher tRFC.Quote:

But back again to my problem I'm not even sure can they run stable at 600mhz cl5, they are rated at 400mhz cl4 - but getting them to work would be awesome. :D
What about straps?
Does strap 266 requires more vMCH than strap 400? If so what timings are changed when changing the strap others than PL?
How high?Quote:

Ok, thanks. But does tRFC have any impact on performance?Quote:

Anyway probably I won't ever need them to work @ 600mhz, planning to get e8500 and fsb at ~550 1:1 to ram would be gg to me, but seeing my [as I thought till few days ago] crappy ram working stable at 600mhz is what gives me strength to overclock it. :D :D
BTW: I remember the talk about some bugged divider but I don't remember was that about Rampage Formula and which divider it was, do you know anything about it A-Grey?
EDIT: About Skews what's better to set? Auto or Normal?
clock twister I continue in moderate?
lvl perfomance I continue in 6 ?
Latencies 5-6-6-18 ? for 1200mhz?
Try with delaying the DRAM CLK Skew on Channel A/B with 50ps ?¿? These assurance
remembers that I want 1200mhz in fewer voltage , helpme

eyes my memory is 1150mhz not 1200mhz
Yes, higher timing is lower performance. Try with 62 and if you get it stable you can always try with a lower timing.Quote:

I leave them on Auto if I don't need to change them. For my 8 X 465MHz, DDR 1239MHz and tRD 6 setup, I have to delay Channel B with 50ps:confused: and Channel A Normal.:shrug:Quote:
EDIT: About Skews what's better to set? Auto or Normal?
But it isn't 100% stable. I'm bugged with random failures on this setup, it's basically useless for me to use that one. I'm running at 3.6GHz, DDR 1199 and tRD 6 right now on low voltage to save some money on my electricity bill.:D:rofl::ROTF:
Can't set 62, only 60 or 65.Quote:

Big thanks for advice with lowerling tRFC, you saved a lot of mine time which I would probably spend for finding best skew combination. ;p :up:

Eye I tube a few ocz pc9600 of 1200mhz and they were not giving not 1140mhz for anything I say to you
Hmm, looks like the system is stable in MemScope but Linx throws me an error. :(
BTW: Loaline Calibration boosts up only CPU voltage, right?
LLC locks Vin = Vout for Vcc/Vtt at voltage regulator. So you don't get droop, it compensates for drop across the reg and traces, and boosts voltage between in and out. Thats all it does really.Quote:

Linpack errors are usually GTL / DRAM clock skew related. Under heavy load that Linpack creates you experience greater clock shift, and jitter and if it is too much shift / jitter it'll be visible in Linpack.
Ok, thanks.Quote:

And I left my PC for overnight with Linx ran, got up few hours later to check how's Linx is doing and it got stuck at 47 loop out of 100 with some error, so I went back sleep without turning it off but when I got up few minutes later I saw BSOD on my LCD. :(
47 passes looks pretty good for me but I don't really know what I can adjust, should I mess with DREF? Or maybe with Skews?
I dunno why my PC god BSOD overnight in idle, yea you can say it was because LLC enabled, but till I started clocing my ram at 600 I was clocking it at 540 with LLC enabled and never got any random BSODs. :(
Your in the right strap and your running at right DDR speed to start experiencing random failures.:DQuote:

Did you use the CPU and NB Clock Skew?
When your Memory needs 2.3V to run stable there is nothing you can do about it. The board can run fine with low Memory voltage but you need Memory that can run stable at lower voltage.Quote:

Haven't tried to use CPU/NB Skews, same as I haven't with NB GTL and tREF.Quote:

vDDR = 2.2
Timings = 5-5-5-15
And on Rampage Formula I added
LLC = Enabled
A/B Skews = Advance +300
All other settings on stock/default/auto settings and haven't got any stability problem back before when I was using IP35-PRO and now when I'm using Rampage Formula.
IMO the problem is with my RAM, I'm not sure can it be clocked so high.
Anyway I'm kinda curious why my mobo can run ram at 540 on stock vMCH but to get 600 I need to raise it by 0.2v. :confused:
I use CPU Clock Skew Delay 200ps and NB Clock Skew Delay 100ps. This lets me run stable with 1.33V for North Bridge Voltage in the BIOS. Without these delays it isn't possible for me to get it stable with that low voltage. Maybe with my Quad it would be impossible to have that stable without the delays.Quote:
