at this moment my “DRAM Performance Control” is:

Performance Enhance.............................[ Turbo ]
Extreme Memory Profile (XMP)....................[ Auto  ]
(G) MCH Frequency Latch.........................[ 333   ]
System Memory Multiplier........................[ 2.40B ]
Memory Frequency   ..............1066...... ......1020
DRAM Timing Selectable..........................[ Manual]

first it was like this

Performance Enhance.............................[ Turbo ]
Extreme Memory Profile (XMP)....................[ Auto  ]
(G) MCH Frequency Latch.........................[ 400   ]
System Memory Multiplier........................[ 2.0D  ]
Memory Frequency   ..............1066...... ......890
DRAM Timing Selectable..........................[ Manual]

then I tried to follow what PortCitySlim said and what i was in the link I mentioned to higher my ram frequency.

2.4 multiplier wasn’t available when latch is @ 400, but it was @ latch 333 (and came with the letter B not D)

i'm thinking of giving 2.5 a shot to bring the frequency a little bit higher than 1066 since my memory voltage now is set to 2.1 (which my shallow knowledge gives me a feeling that my current frequency doesn’t require it )

At 425fsb you should be using the 266/2.50A. If port sent you my template the only reason its set to 2.00 is because this ram will not run with the 2.40B strap at 482FSB. For me 2.00D at PL9 gives me slighty better everest scores than 2.00B at PL10. Also am I seeing that correctly you have PLL set to 1.15?

[Jor3lBR]

you can take off the NB and heatpipe hold the MOSFET's HS and hold the heatpipe and twist heatpipe it and it should pop lose, i did it with mine and it worked need to take off the v-card to slide out the heat pipe

It is recommended to uninstall the Heatpipes from the motherboard then use a hair dryer to heat the double sided tape that hold them together and then twist them out.

Never do this with the heatpipes attached to the mobo.

[simone18]

i've just bought another ud3r, now i've a pair.
just a question at the moment: how does work xmp? is it really useful?

@jor3: does domino liquid cooling works well? maybe i'm going to buy it

well it worked and i didnt feel like taking out the mobo to take off the mofest hs off


thats why i like my Danger Den Torture Rack

The first thing that catches my eye is your MCH/DRAM Reference. I would adjust this to 1.050 like your channel A/B reference. These settings I gave you last night for 2.1v RAM are exactly the same settings that Hoss331 is using for his overclock stability and they are passing 8+ hour Prime95 blends. I use a lower ram voltage but it lowers down easily enough, for every .02v you lower your RAM you will notice that the reference for that lowers .01v. I am at 2.00v RAM and a 1.000 reference.

aha ... so the "MCH/DRAM Reference" is somehow connected with A/B reference?
I’ll set it to 1.050, but do you think I should try to lower the ram voltage a little bit?
2.060 with 1.030 A/B reference and MCH/DRAM Reference? like what you gave Hoss331 here ?

Leaving your CPU TM and No-Execute might not cause you problems(I used to run with them enabled). But remember down the line when you try a blend/OCCT RAM large ftt packet test that disabling these can sometimes solve buggy instability problems.

ok I’ll disable it, I just thought that those would help me not frying CPU or Memory

Setting your performance enhance to turbo might not improve your performance overall, after tweaking you might get better settings to boot on standard. I would say that you should start with Standard and after your finished tweaking everything see if you can run on Turbo

will set it to standard, I just kept it to Turbo cuz that’s what it was when everything was at stock

do you think I should set “Static tRead Value” at 8 instead of 9 like your settings? Specially that mine already shows 8 as a default value!

didn’t really understand but I’ll give 266/2.50A a shot
you mean "CPU PLL"? it's @ 1.50 not 1.15

manny thanks for all the help everyone

[Allubz]

Sounds perfect, thank you a lot!

[dnottis]

Finally...had to use 333 strap and GTLs needed to be .838, its prime blend, small and LinX stable over 4.0Ghz.

[simone18]

very well. what about vcore settng in bios? does it vdrop a lot?

[radaja]

if any one is interested im selling my two g.skill pc8800 kits 2x2gb for a total of 8 gigs and my E8500 EO Q827A272 in the F/S section.i just got my first set of g.skill 9600's and soon to be getting another,so no need for the 8800's.

It came with F6 but so far F8F has been better to me. If I run into issues I'll try F4. What were you able to do with F4 that was giving you problems with the newer bioses? Higher Fsbs? Stability?

Better stability and higher FSB. As a reference test, I used F4 and kept everything on auto except vcore, PLL, and VTT. I was able to run 471x8.5 P95 stable for an hour. Every other BIOS with the exact same settings (vcore, PLL, and VTT were manually set to the same options as I did in F4) failed P95 within 10 mins.

I switched to F4 to hit what I did above. Thanks for the tip seems to be working well for me!

hmm... i think i wanna try it out also mine cam with the F6 for my Q

cuz does it flash back easy or i need to do the same crap with asus mobo to flash to an older bios ?

also anyone know which one os good for dual cores [E8500] ?

Put F4 on a flash drive, reboot, go into bios hit F8 for Qflash and flash it like using AltF2 on an Asus, was cake and no issues going back either.

thanks right now im on F7 but wanted to try F4 since it should be better for Q BRB

i've a xeon x3370 under bios F5. i should try to flash F4 for some tests

@dnottis what are your settings ?

also can you try 8X500 ?

Load-Line Calibration
CPU Vcore
CPU Termination
CPU PLL
CPU Reference

MCH Core
MCH Reference
MCH/DRAM Refernce
ICH I/O
ICH Core

DRAM Voltage
DRAM Termination
Channel A Ref
Channel B Ref

[SpeedEuphoria]

I also am currently trying F4

So far its good

[Touche]

If you benchmark under disabled and then under enabled and compare that to your results on auto you should be able to detect what the auto setting is doing.

I've just benchmarked with Everest and there's absolutely no difference between enabled/disabled/auto.

[simone18]

I've just benchmarked with Everest and there's absolutely no difference between enabled/disabled/auto.

i've tried too. no difference.

[dnottis]

Load-Line Calibration - enabled
CPU Vcore - 1.34xx (dont recall which one, but it's one of the 1.34 options)
CPU Termination - 1.26v
CPU PLL - 1.57
CPU Reference - .838

MCH Core 1.26v or 1.28v
MCH Reference .838
MCH/DRAM Refernce AUTO
ICH I/O - lowest selectable
ICH Core - lowest selectable

DRAM Voltage - 1.82v
DRAM Termination - AUTO
Channel A Ref - AUTO
Channel B Ref - AUTO

also can you try 8X500 ?
Yep but my chip doesn't like 500. It boots but it's very unstable.

[simone18]

i suggest to manually set the mch gtl and to increase cpu gtl

[PortCitySlim]

I’ll set it to 1.050, but do you think I should try to lower the ram voltage a little bit?
2.060 with 1.030 A/B reference and MCH/DRAM Reference? like what you gave Hoss331 ?

Sure lower it away, if it passes keep lowering it

will set it to standard, I just kept it to Turbo cuz that’s what it was when everything was at stock

do you think I should set “Static tRead Value” at 8 instead of 9 like your settings? Specially that mine already shows 8 as a default value!

SURE! That is what I was meaning about using standard and trying better Tread values and write training. Set your to stardard and see how low your Tread value will boot, that is after you get your multi and ram speed set to your liking.

didn’t really understand but I’ll give 266/2.50A a shot
you mean "CPU PLL"? it's @ 1.50 not 1.15

manny thanks for all the help everyone

I would follow Hoss331's advice with setting a higher RAM Multi, Hoss helps me with my settings and is pretty good at this stuff.

Use .63x as the multipler for figuring out GTLs.

VTTx.63=GTL voltage

So, if VTT is 1.20, do 1.20x.63=75.6v, or in this case you would chose .76v in the GTL list. Same method and format goes for the NB. Using that formula I was able to get a CPU-Z validation with my Q9550 at 555FSB on air

[PortCitySlim]

ok I’ll disable it, I just thought that those would help me not frying CPU or Memory

I would not worry about the Thermal Monitor and your current overclock. Your not going to experience high load temps so Thermal Monitor is going to be useless for you. Even at my clock speeds sometimes I do get my chip a bit hot(If I linpack) but the important thing to do is monitor your temps and even if they get above 70C as long as your not running that hot for a long period of time your not going to "fry" one of these Q9550/Q9650 chips.

[Touche]

i've tried too. no difference.

Done some more testing - no difference in Everest benchmark but there is in stability. DDR Write Training Enabled gives me Linpack errors. I've set it to disabled.
