ASUS P5Q3 Deluxe discussion

[K404]

Hey pmp How important do you think the Write- Precharge and tWTR delays are for high RAM MHz? Iv been keeping mine around 14-16 for both.

Cheers, and nice numbers!!

Frankly i never tried to up them to see if it affects speed abilities. Maybe Tony or Bachus would support us with their great RAM knowledge

[Tony]

Forget 1600 with Micron for now, bachus may be able to do it but i can't with the boards I have here, and many other can't and this in not just with 2GB OCZ modules. I can kill 1600 scores at 1333+ so whats the point of worrying about it. If 1333 is faster than 1600 why do you all want 1600?

I will post my settings once I hit 200% coverage, you will not believe the skews i am runnings

@BulldogP0
Probably ( I don't have the board here with me ) under the circled capacitor:

What pin on a DDR3 slot is the Vin?

Agree with that. I spend some time on fighting with D9JNM 2x2GB setup and best i could do stable was something around 1420 MHz

0801 bios did help, memory works now fine at 1600MHz 7-7-7-18, 1.95V now.

yes but is it stable???

The options for FSB/RAM mixes apart from anything else 720-770MHz isnt a versatile range at all....

1333 may be faster with a higher FSB... (415 compared to 500)
but surely if the same FSB were used for both mem speeds, 1600 should give a higher bandwidth at least?

[Tony]

My setup for 500fsb 1333memory, skews are pretty wild but it is 100% stable.

Have a look here for the settings

CPU is at 4.25GHZ in these settings

FSB may be higher but I gave away bus speed and TRD to the 1600+ run.

[THUMPer]

Im going to pick this board up. Using this RAM
KHX12800D3K2/2G
I also have 2 36GB Rptors I run in RAID 0 on my P965. I hope to have some luck. Since that's all it seems to be. Or if you think I should just go x38 and get it over with. hah

[Fitseries3]

TONY....

i tried your settings and my board posts fine. the NB seems low compared to my other settings though. i cannot get rid of the instant BSOD when windows tried to load.

what chip are you using with those settings?

im using e7200 but will try my e8500.

[GAR]

I have since returned this board, it was the worst motherboard compatibility i have ever had in 15 years of building computers, i am not going to buy new products again, wait months for the problems to be solved.............DDR3 is problems for now, intel chipsets suck because memory controller is on the NB and not on the cpu........that is where AMD wins, and i cannot wait for the day that AMD makes a comback, hopefully its in the next year.

[THUMPer]

^I think he said it all. Maybe I will wait a month

EDIT:
Pulled from the Asus Website
"DDR3 2000(O.C.)/1600, it is suggested to use one DIMM per channel"

This means what? You can't run Dual Channel?

[GAR]

The sad part is we the customer is the test dummy.......they dont spend time and money because they know we will do the testing for them.

and BIOS 0804 just arrived, 1600 is working on Micron now, just need to tune it now and see if it is faster than 1333 yet. Samsung is fine at 1600 by the way but CAS is too high for my liking in order to get absolute stability.

Where the hell is this 804 BIOS? Asus's site still shows 0704

I have gotten myself an ASUS Rampage Formula with some g.skill 4gb ddr2 8500 set, x48 is better for me because of the 4850 crossfire i will be using....

[DiscoTech]

So where can we get his new 0804 bios?

You're right, Pyr0. I run a quick test @ 500FSB/1600C7 and it turned out to give a better result than 1333C6 Tony posted - not a huge difference but enough to counter the claim on "1333C6 destroying 1600C7". I don't want to argue here, I just felt like correcting an unfair statement being made. Apples-to-apples is the only way to compare.

All secondary memory timings, CLK skews and other memory settings at AUTO, except for Transaction Booster @ 8 (AUTO sets it to 10); all voltages as in previous 1600C7 post

P5Q3 Deluxe, C2D E8500 @ 500FSB / DDR3-1600 CL7 @ 1.80v - SPi + M4W
This is TW3X4G1800C8DF based on Samsung ICs - 2 x 2GB DDR3-1800 8-8-8-24

As Gary mentioned, new 0804 BIOS has been passed on for testing. From now on, it will only get better

[Tony]

leave it Bachus, if this continues i will be forced to leave XS and I doubt this is something Fugger wants.

I said my piece...you spoke out of turn...end of story. My work produced the 0804 and helped Micron users, all you did was show samsung worked fine.

You need to ask yourself what you are actually giving to the community and what you are just doing for Corsair

[Telo]

So where can we get his new 0804 bios?

As the man stated, where is the famous BIOS? Didn't see it on ASUS download page.

[BenchZowner]

It's still a Beta BIOS, and only a few beta BIOSes are made available to the public.
You won't find it on Asus's public FTP.
