Some things do not add upm please review DRAM Performance Control.
Try to set MCH Core 1.24v if you can do so.

Re: Wow, you guys are awesome

Reviewed DRAM Performance Control. Settings are as shown above:
DRAM Performance Control
Performance Enhance...................: TURBO
Extreme Memory Profile (X.M.P.).....: Disabled
(G)MCH Frequency Latch...............: Auto
System Memory Multiplier ..............: Auto
Memory Frequency (Mhz) ..............: 1066
DRAM Timing Selectable ................: Manual

Changed MCH Core to 1.24.

Ran Prime95 for almost 8 hours with no errors.

I can do a long Memtest run while I'm out today.

No they can't be, either XMP Auto/profile or multiplier is 3.20B

Re: Wow, you guys are awesome

I went back and double checked and that is what it says.

X.M.P. is DISABLED.

I does have (SPD) to the left on two lines though. That is:

System Memory Multiplier (SPD): Auto

and

DRAM Timing Selectable (SPD): MANUAL

That is different from the template, which doesn't show the (SPD) notation.

And for those settings MemSet will show 533MHz?

[wallypiper]

Re: Wow, you guys are awesome

Ya got me? I don't know anything about Memset. I run it and get the screen shot.

Seems like I read an explanation somewhere about how with DDR2, the memory speed gets reported as 533 when it's really 1066, (or 400 when its 800 etc) but I can't find that now.

Re: Wow, you guys are awesome

DDR(Double Data Rate) memory makes two data transfers per clcok cycle, therefore it is rated twice it's clcok frequency.

I was just asking if for those settings MemSet still reports 533MHz or does it report 400MHz?

Re: Wow, you guys are awesome

533.3 in the "System" area at the top of the main Memset screen. See the screenshot in post 31 above.

Yes I see it, though it makes no sense, since XMP is disabled and Q9550 default bus frequency is 333MHz it has no reason to set 533MHz and should have been set to 400.

Re: Wow, you guys are awesome

CPUZ reports 533 also.

Re: Wow, you guys are awesome

I've got the F10 bios release. Waddayathink?

And while I'm on the subject, when I unzipped it, there were some other files with it:

autoexec.bat (wow, haven't seen that in a while)
FLASHPI.exe
and the bios file, itself, P45UD3LR.F10

I don't think I've encountered that before when downloading a bios update from Gigabyte. Got any idea what they're for?

The batch file is "flashspi P45UD3LR.F10". Some kind of DOS bios install utility suppose.

Re: Wow, you guys are awesome

Yes those for flashing from DOS, it's the standard package when u load from GB site.

Probably a good idea to flash the new BIOS since you experiancing problems.

Re: Wow, you guys are awesome

Yeap ^^

All you need is the .Fxx BIOS file if you are flashing with Qflash, which I do suggest.

[wallypiper]

Re: Wow, you guys are awesome

OK then. I've used Qflash before with no problems so maybe this evening.
If I want to drop the ram speed back to 800, what settings do I have to get to that? I'd rather have stable ram at 800 than quirky ram at 1066.
