EXPANDER, nice work man

just used a old mcw30 swiftech chipset water block screwed right in to the top of the stock nb-sb-vrs heat sink and keeps the temps in the 30s

il take a pic if anyone cares to see it

Great work mate ... nice to see the good old P6T Deluxe in action ... Proves once again ... its more than capable of extreme results

How did u do that? Pics...

Sorry to bring up another subject. I have been trying to find out about this and what is going on for a month now. Why are my memory reads so low? Here are the system voltages. I am using the 0006 bios.

Memory 1.66V
CPU 1.368V
QPI 1.35V
PLL 1.82
IOH 1.18
Memory is set to 8-7-7-21 everything else to auto.

hmmm

p6t delux v2

it only sees 2 of my 6gb of ram?

each stick passes in slot 1

cpu z shows all mem but bios and windows dosent?

any ideas people

bad imc mobo or settings

I was having the same problem with my new rma kit of Kingston Hyper X 2000 C8 Elpida Hyper. What memory do you have? I just read a great article over at Madshrimps about B2B on Asus X58 boards and how you can't get DDR3 933+ stable without setting B2B 10 or 12. Default is set to 0.

I couldn't get this new kit from Kingston stable cas7 or cas8 until I set to 12. After setting B2B to 12 I was quickly able to get 7-8-7-20-1T-88 stable 1.52vQPI, 1.72vDimm.

And here's some results with my G.Skill Trident 2000CL9 BBSE

same kit as you bro
i was reading your posts on that thread but 12 dosent help.... ill try your voltages

thanks man


NOPE still only sees 2 of 6 in bios

i have the same ddr3, bios and all dont know?

[hetsaq]

Is there any trick to go to from a 0006 Cross flashed V2 back to the newest bios for the V2? Do I still use Afudos or the Asus flasher? Thanks!

What slots do you have your memory in? You have same kit as me? Same model #? Elpida Hyper ics? I have my memory in the 2nd set of slots (orange). I have found these slots better for overclocking with my last 3 Asus boards. If so then you should be able to set my same settings. I would start with 8-8-8-21-1T and test B2B 4-10-12 and see if you get stability on any of them.

I will get you those BIOS screenshots in about 1.5 hours. You may have something enabled or disabled that I don't.

So.... time for big ass picture

Can anyone tell my why my 3x1GB Kingston kit is only showing up as 2GB in the BIOS and under system info but under CPU-Z it shows 3GB?

EDIT: I moved the sticks around, now seeing all 3. What a weird thing...

[Crow-]

Have you tested your power supply?

My PSU was good enough, but I bought a new and better one, and I still have the same problem

[astrodanco]

I'm running with 12GB (six sticks) of Corsair CM3X2G1600C7 and it appears to work well.

[Amurtigress]

Hi people,

you might have read about my problem with the Corsair CL8 kit, one stick not being detected. I had my RAMs replaced 9 days ago...

I went to the store thinking it was an easy issue. But after 1 1/2 h of testing they told me that all memory sticks were found by their test system. I insisted on seeing it with my own eyes, and indeed...they used a Gigabyte S775 board that really found all of them while on my P6T Del. V2 one appeared to be dead.

To make it a bit shorter... The store manager still replaced my RAMs, I saw other Corsairs in his box of triple channel kits. My CL8s were Revision 3.2 (Micron chips) and the ones I have now (CM3X2G1600C7) for an extra 10 Euros are Rev. 2.2, which translates to Elpida chips...

I hope they're no Hyper ICs. I don't want to lose another set of RAMs and have those service-incapable suckers send them back to Corsair for warranty replacement...

(see Elpida Hyper graveyard)

[meww]

The problem is not with your ram. It is with your voltages in the bios.
Just bump your bump up the QPI voltage first 2 notches and if that doesn't help. Bump up your IOH voltage and IOH pci voltage and ICh voltage and ICH pci voltage. Bump all those voltages 3 notches, if this helps start bringing them down to a lower voltage that still picks up all your ram.

[HDCHOPPER]

Also may want to reseat CPU

[Rasmus66]

Is there any trick to go to from a 0006 Cross flashed V2 back to the newest bios for the V2? Do I still use Afudos or the Asus flasher? Thanks!

You can use both

[Amurtigress]

Meww, HDCHOPPER,

it can't be the voltages, nor can it be the CPU seating. If you're going back to my first post about it you'll see that I tested EACH memory module ALONE in the fist orange socket. And only ONE of them would always be dead and not even start posting the system. So either the CPU seating keeps the whole socket dead or not at all, but not one memory stick alone...

Anyway the problem is solved. Hail Elpida CL7 chips...

I got the Asus p6t Deluxe (v2) recently and I had a bad orange DIMM slot (middle one). I had to return it for another and the new board has been running great. I'm a bit of a wall with 4.4ghz HT off 1.39vcore 1.92pll and 1.3/1.3 for ioh, 1.66v mem with the Corsair XMS 3 CL7 6GB kit. I really can't complain. I've been trying to figure out if it's worth it to enable HT and go for 4.2ghz or leave it off and go for 4.4GHz as my 24/7.

I've read all over that setting QPI above 1.35 is bad, how dangerous are we talking when going above 1.35?

You should look at this thread: http://www.xtremesystems.org/forums/...d.php?t=207972 (vtt is qpi voltage)

I have held my qpi voltage at 1.575 nearly a month, no problems and degradation, but now is at 1.45 and i think that up to that voltage is safe enough if you have good cooling.

Good cooling for the CPU or for the north bridge?

Well at 4.4ghz I manage about 73 under full prime95/occt load (not linpack ) with a lapped TRUE. I thought that the QPI voltage mostly just helps with RAM overclocking, does it also help when you are having CPU crashes on prime95 small fft? I've got a solid 750W. I might have to have another run at 4.6GHz with 1.4-1.42vcore and higher QPI...hmmm (Just got an i7 from my q6600 in the last few days so I'm adjusting to the Overclocking on this platform)

[edc]

From my experience, small ffts will fail only if qpi/uncore/dram is very unstable. I have run in prime95 24h small and 24h large ffts, perfectly stable, but linx failed after 30min. I raised qpi for 0.025v and system during linx is now stable.
After that, I am using prime95 for testing cpu core stability, linx for qpi/uncore stability, memtest for testing dram stability.

I have crossflashed my P6T SE to P6T so now I should be able to use sli. I wonder if it is possible to flash it to P6T Deluxe or Rampage 2 Extreme ? I flashed my P5E x38 to rampage formula x48 without any problems and I had more settings and more stable vcore with that bios with my E8600.
