Would be great if you also post your definition of "compatibility" cos there may be different definitions of "stability".

Compatibility means motherboard takes this memory no problem to run in our rated speed.

most the incompatible motherboards will not boot at the memory rated speed. Even if it boot, it will not load into windows.

we use SP2004 blend with memtest at the same time to make sure all memory address used.

moreover, if memory unstable, system will not pass sp2004 with memtest.

We saw your suggestion but to us that is overkill for memory test

thank you

Thank you, this was really eye opening.

i order in 2 x 4 gig kits,not sure if its the 902 bios or its the asus striker 2 formula.hit and miss if it wants to post.have you guys tested it yet?

not yet
but Asus p5n-d 750i has problem to reach 1066 even with micron d9. no matter it is 4 dimm or 2 dimm installed.

evga 780i is good with our ram. for daily use, evga 780i is better choice

Could you post the auto values inspected by memset just for reference?
Thank you.
I have formula if possible.

Does this mean the whole series? I have the DK P35 model and thinking of going for a 4 x 2GB setup.

Hi

I have a Maximus Formula (bios 0906) with GSkill 8500 2x2GB.

I cannot get it to post with both sticks of RAM in the computer. Either stick alone is no problem. The LCD poster freezes at "DET DRAM".

I have manually set the bios as follows:

RAM volts = 2.1
1066mhz
2T
5-5-5-15

Any help appreciated. Motherboard currently sitting on bench with only a video card, keyboard and mouse plugged in.

I have achieved post by booting RAM at 800mhz but this produces a constant stream of errors in Memtest86+ v2.0.

Have I got faulty hardware?

Thanks

can you set tRFC at 52? This is the major impact on Asus.
Also post your fully timings.

Hi Spyrus,

Thanks for the reply. Please find my bios settings below.

I'm at 266 FSB (not overclocked yet) with a Q6600 (eventually I will be at 400 FSB or just above because that's what it ran at in my last motherboard).

I have tried tRFC at AUTO and at 42. 42 is the highest value I can select on the Maximus Formula.

Transaction Booster and DRAM Static are both at AUTO. But I have tried with both of those disabled. I have also tried with the Northbridge voltage at 1.65v and with the RAM voltage at 2.2v.

The RAM works perfectly in my friend's P5E.

Thanks.

I get "DETDRAM" as well on Cold Boots, Restarts, and pretty much whenever the RAM just doesn't want to behave properly. Search my posts, you'll be able to see easily. Seeing this RAM on the QVL list was one of the reasons I decided to go with the 4GB PK.

Just today, restarted my PC to lower vcore and NBv which should be no problem to post, and DETDRAM. Remove HK's, put in ddr2-800 stick to go into Bios and restore settings. Restart, unplug, put in HK's and DETDRAM. Restart, DETDRAM. Put in 800 stick, up vdimm, restart, put in HK's and sometimes it will POST. Then I pretty much work with that until I ABSOLUTELY have to restart. Regardless of voltages on vdimm,nbv,vcore. I even tried bumping the DDR2 Reference Volts up +10mv on each channel.

Heard part of the bug is SPD table related because of the huge variance in default vcore on 800 vs. 1066 2.35v on 2GB HK's.

The HK's for me involved buying a 3rd stick of RAM to set the bios properly. Even then, DETDRAM, voltages go to default, have to remove the RAM and recalibrate with 800, to get it to POST.

That is not have it is suppose to work. Board defaults to ddr2-800 1.9v, SPD Table should too. So I requested an RMA today for my 2GB HK's, and I'm gonna pray that DETDRAM is a non-issue with these 4GB PKs.

Oh man I hope this isn't the case. Hopefully it's just user error on some bios setting like Trans Booster being disabled-0 for 333, and enabled-0 for 400.

This might be helpful. For 2x2GB sticks try the combinations for PL=tRD=8 first and then try for PL=7.

You have many auto values.
Try these:

Ai Overclock Tuner : Manual
OC From CPU Level Up : AUTO
CPU Ratio Control : 8
FSB Frequency : 266
FSB Strap to North Bridge : 266
PCI-E Frequency: 100
DRAM Frequency: DDR2-1066
DRAM Command Rate : 2T
DRAM Timing Control: Manual
CAS# Latency : 5
RAS# to CAS# Delay : 5
RAS# Precharge : 5
RAS# ActivateTime : 15
RAS# to RAS# Delay : AUTO
Row Refresh Cycle Time : AUTO (Really that will do it you can check that with memset or bios if is 52)
Write Recovery Time : AUTO
Read to Precharge Time : AUTO

Read to Write Delay (S/D) : AUTO
Write to Read Delay (S) : AUTO
Write to Read Delay (D) : AUTO
Read to Read Delay (S) : AUTO
Read to Read Delay (D) : AUTO
Write to Write Delay (S) : AUTO
Write to Write Delay (D) : AUTO
DRAM Static Read Control: Disabled
Ai Clock Twister : Light
Transaction Booster : Disabled
Level : 2

CPU Voltage : AUTO
CPU PLL Voltage : AUTO
North Bridge Voltage : 1.55V
DRAM Voltage : 2.0
FSB Termination Voltage : AUTO
South Bridge Voltage : AUTO
Loadline Calibration : AUTO
CPU GTL Reference : 0.63x
North Bridge GTL Reference : 0.67x
DDR2 Channel A REF Voltage : AUTO
DDR2 Channel B REF Voltage : AUTO
DDR2 Controller REF Voltage : AUTO
SB 1.5V Voltage : AUTO

NB LED Selection : NB Volt
SB LED Selection : SB Volt
CPU LED Selection : CPU Volt
Voltiminder LED : ENABLED

CPU Spread Spectrum : Disabled
PCIE Spread Spectrum : Disabled

But you will have more luck especially with strap 333 and divider 5:6 bringing memories on 1000+. Put definitely auto at tRFC.

Handy chart for figuring out Performance levels, I'm currently giving it another go after see that.

Edit: DETDRAM on Cold Boot still and issue. SPD Tables are too low for this to boot on 1.9v even defaulting to 800. I can reboot just fine, trying to Cold Boot is a no go. Once everything defaults due to failed overclock, DETDRAM on Boot up.

Put them on white slots.

Are they compatible with Asus P5E X38 chipset? I would guess they are as the Maximus Formula is and they are fairly similar.

I had also warm boot issues and that is done at certain fsb/divider/multiplier combinations.

For example tried 9x450@540 boots/reboots fine
8x450@540 reboot no go & 9x449@538 no reboot / boot.
So try to change a little fsb +/-1,2

I did some experimenting today...

Calibration Stick: Super Talent 800 on QVL
Memory: 2GB 1066HK

Slots:A1 A2 B1 B2
using 444x9 ddr2-1183 400 Strap
Performance level 7,8,9 have no effect on stability past DETDRAM. :(

-Put 800 stick in A2
-Failed Overclock, Enter Bios, Change nothing...hit F10
-Save then Restarts
-Pull Power Cord before it boots the Overclock settings.
-Take out 800 completely.
-Put in GSkills in A2 and B1
-Power Up Computer, Mobo Shuts down with new SPD
-I then Pulled the Plug before it Powers up again.
-Put B1 stick in B2 slot for DC mode.
-Plug in Cable, Power Up PC
-PC POSTs and passes DETDRAM.

I've heard of the B1 slot trick, is this along those same lines?

Asus X38 Maximus Formula

Confirmed Compatibility. :)

-No more DETDRAM issues.
-Boot even on Failed Overclocks at default 1.8v Max Formula uses.
-333 Strap currently Testing: Will push tonight.:up:
-All Timings on Auto on DRAM @ 1.98~2.1v
-tRFC 52 on Auto

Two to report:
Using just two DIMMs, not four, DFI P35-T2RL was almost stable (Pass 7 of 8, Test 6, 181 successive errors).
5000+ Black Edition with a DFI 790FX-M2R was a C1 and did not boot.

I have struggled for long to make my G.Skill PC8000 stable on ASUS P5K Pro. Nothing seemed to help, i could not make it pass Linpack.

Recently ASUS released new BIOS with wider selection of tRFC. I tried tRFC 55, and magically all errors gone! Previously it was set by SPD at 52, and maximum manually selectable value was 42.

Previously I have tested it on Gigabyte GA-P35-DS3P, which had wide selection
of tRFC from the beginning, and could not make it stable regardless of tRFC. So i decided tRFC can't be possibly a culprit here. I was wrong.

So, for this memory tRFC 52 is NOT enough at 1000MHz.

I have tried Powerchips (On Abit and Maximus Formula) the Mushkin XP6400@4-4-4-12 and Redlines@1000@5-5-5-15 both could boot at 1000 with tRFC 43 but to past 520+ tRFC has to be 52, but 55 is too high i think

To pass Linpack 64b at 1000MHz then 8GB is installed,G.Skill F2-8000CL5D-4GBPQ needs tRFC 55 (maybe less 54-53, have not tried ), 52 is not enough. Regardless of voltage.
