G31M-ES2L + PC-8500 issues

[simsandwhich]

Hi all,

I'm having trouble getting my RAM to clock at 1066mhz (PC-8500). It shows up as 800mhz (PC-6400). I'm not sure exactly what settings to tweak, and to what, to resolve this problem.

I'm familiar with the BIOS so I'm not an entirely lost cause :)

Specs are:

-GIGABYTE G31M-ES2L rev. 1.0
-2x2GB DDR2 Corsair XMS2 PC-8500 5-5-5-15
-Intel E7500 Core 2 Duo @ 2.93ghz

Links to manufacturer's pages are:
RAM | CPU | MoBo

Any and all help would be very much appreciated!

System Memory multiplier 4 (4.00A if you have it, otherwise try both you have) and DDR2 OverVoltage +0.3 (for 2.1v, normal is 1.8v).
It doesn't seem you have any others.
Could you post a screen capture of MemSet main (click >>) and SPD(click spd) windows with BIOS optimized defaults applied?

Sure, here's the screen capture with BIOS set to optimised. The only multiplier options I appear to have are 1.0, 2.0 and 3.0.

Thanks for the response :)

Memory multiplier 1? That's the 1st time I hear of.
What is the BIOS version?
Try to press Alt+F1 in main BIOS screen and see if that add any more options in MIT.
With 266FSB a multiplier of 4 is needed for DDR-1066, but for 333FSB 3.2 is needed so I realy don't know what to say.

Oops, don't know what I was meaning before! Multiplier options are 2, 2.5 and 3 (not one :P )

advance options doesn't add any more options to the SPD. BIOS version is f10, if that means anything.

Re: G31M-ES2L + PC-8500 issues

F10 seems to be the latest.
it's still odd because DDR-533 is not even listed on the web page, and that's what you'd get for 266FSB with 2 multiplier.
Send a question to GB support and see what they have to say about it.
I wouldn't worry too much about it because DDR-1066 would not be a lot of improvement over DDR-800 at 266FSB.

Will do, intersting to see if Gigabyte can explain what's going on

Have you already loaded optimized bios defaults from the main bios screen?
Did you try pressing <ctrl> [Ctrl] + [F1] <f1> from the main bios screen before you entered the M.I.T. section?</f1></ctrl>

Try these settings:
CPU Clock Ratio ---------------------- [9X]
CPU Host Clock Control --------------- [Enabled]
CPU Host Frequency (Mhz) ----------- [333] --> 9x333 = 2.997GHz
PCI Express Frequency (Mhz) --------- [100]
Performance Enhance [Standard]

Then see if you can set:
System Memory Multiplier (SPD) ------- [3.20] --> do you see additional options with the above settings?

Note:
DDR2 OverVoltage Control ------------- [+0.3]
FSB OverVoltage Control -------------- [Normal] <--- +0.1 might be needed
CPU Voltage Control -------------------[Normal] <--- this might need to be a bit higher

Keep in mind that running your memory at 800MHz with 4-4-4-12 primary memory timings will be similar to 1066MHz with 5-5-5-15 timings.
