Sorry,maybe i resized too small,try again.Thanks

That looks good.....except for the rams. It shown in CPU-Z as SINGLE speed.
Unplug power....and reseat them in either slots 1&3 or 3&4 accordingly. (in the same color code slots)

Hi! SamSaveMax,my friend give me 2 sticks for a try (OCZ 2 GB PC2-8500 DDR2 RAM :OCZ2N1066S2GK), i put in MOBO and set FSB 450, dram timing 5-5-5-15 even 17 or 18 Vdram 2.2 boot into windows run prime only 2 minutes and fail. You know what's timing for that ram setting? Help,please. Thanks Joe.

Don't make an instant leap like that would results failure.
10MHz increment is a rule of thumb.....then from 460 to 480 use 5MHz increments.

Don't forget to add more Vcore as you go along.
......and sometimes....you may need to loosen the rams too....like 566-15 if needed.
I think that ram specs as follow: 555-15 @ 2.1~2.3volts

Crank that Vcore up 2 notch from the current value in bios (reduce 1 notch later if deems stable)
You have enabled Load Line Calibration right?

Joedo
Your memory seems capable of a good speed.
Max pc performance is going to be around 460 fsb with a 2.4 multiplier or 490 fsb with a 2.0 multiplier.
I personally think the 2.0 multiplier gives better performance,a lot depends on memory timings too.
Higher fsb speed will give you higher cpu speed,but whatever route you go youre going to be around 9-10gb/s max memory bandwidth.Maybe a maximum of 10gb/s read.
tRFC of 48 is to low bring it up to 52 at least while you are testing.
The other settings,well mine are posted back there ,Sams are back there somewhere also.
Mch coreV ..what is it at? etc
 
Hi Sam! I did enable Load Line Calibration,the two value, that's setting by default. I bump FSB 450MHz, up Vcore and change MCH auto to 1.34 on the list,but prime run not even a minute core#3 stop.
To Kick! I look in Bios tRFC it's 56 [Auto],but i don't know why CPU-Z show 48,i'll try to change to 56 and see what's going on? will be post back.Thanks for advice.
 
@kick: On Asus board MCH = NB

@joedo
I've noticed that in this pix....your rams are at 2.10v
What was the input in bios?
Try 1.40 for MCH.....

What are your temps at 450fsb? What's the exact model number of Zalman V6?

Hi Sam!
I left all setting and bump FBS 443 run prime over 1 hour no problem, if push it to 445 prime will stop one of 4 cores after 1/2 hour. In the bios, i was set to 2.2,2.28 or 2.3 still have problem so now Vdram 2.1. The temps at 450fbs @73/68/69/71.
Sorry,can not find the model number of Zalman, only A1-V6 RADI-COOL fan speed can adjust upto 3000PRM+/-10%. I intent put another fan on top of dram, what're you reckon?
 
@sam :eh?: Yeh MCH is NB on all boards ,I wanted to know what Joedo's memory control hub voltage was at in his screenshot.Hes on a gigabyte board too isnt he?.

@joedo When you check memory timings in bios after you post and there is a figure like 56 with [AUTO] beside it ,that doesnt mean it will be 56 when you boot into windows.
Aside from all that tho what are your full bios settings now using a 2:00 multiplier and which 2:00 multiplier is it,B or D?
If you want to see what all your memory settings are while in windows download a utility: memset ,DO NOT use the save button on the utility as it will lock your memory settings to those values for every boot into windows from then on.
Reset the bios to optimum defaults every so often ,especially after a failure .

Its hard to tell,for us, what might need changing from just a screenshot without the full bios listing.
 
@kick! the bios was set at the moment.

A couple of things,not having the exact same memory and exact same board makes things a little more difficult in suggestions at higher fsb ,but anyway.

You will probably need to follow :
1st Sams suggestion of enabling Load line calibration.
Why ?well you are getting .04+V Vdroop under load without it.
a)Your VID is an indicated 1.25 V and your mbrd sees it that way too.
My original Q8200 had an indicated VID of 1.225V but the mbrd put it at 1.23 I think.
I think of VID as being the maximum voltage that a cpu needs to operate at standard speeds.
Like as long as your cpu allways gets 1.25v it will allways run at 2.33ghz
It may run at 2.33ghz at 1.15V but were not really worried about that.

When clocking up tho who can say,but a higher VID means you could need more voltage than someone else for a given cpu overclock.
Whats a safe voltage .
Well all the 775 quads I believe have a max intel approved voltage of 1.3625

For 490fsb on my Q8200 i needed 1.3625 in bios with LLC enabled.
I used to play around with 1.34v and it seemed fine most of the time but sometimes here were errors in testing.

On another forum far far away I have seen some Q8200's having probs around 445,i hope its not like the Q6600's where some batches dont seem to clock as well.

Anyway you could put in 1.3625V in bios now ,even with LLC disabled it should give you sufficent voltage not to worry about the cpu for awhile on fsb increase.

Then MCH voltage,Id take that off auto as suggested above, 1.28 might be sufficient but from what Ive seen ,most settings over 450(1800 fsb) are running 1.30V+
---------------------------------------------------------
The mch latch frequency: I could be wrong , but as far as I know all it does is determine what multipliers you can set for your memory.

If you set it on auto you can use any multiplier in the bios,if you set it at 333mhz all you can use is B multipliers and so on.

-------------------------------------------------------------------------
Performance level in memory channel settings, a setting of 10 should work ok you can enter that manually.9 would probably work too,but may not without more tweaking above 470 cpu ref.

--------------------------------------------------------------------
More things to try
Save your bios config for 443 cpu ref and load up and save optimised defaults
When you repost go into the bios and enter:

1.the cpu reference value you see manually
2.the mch refererence voltage value you see manually
then load and save those bios settings.
Then go back into bios settings and put in the other values that you use for 443 fsb. The reference voltages should scale up automatically.
That way you shouldnt have to worry about ref voltages again.

---------------------------------------------------------------------
cpu pll may need 1.57-1.59 V
cpu term generally aim for the closest V to cpu core V without going over it,may depend on whether LLC is enabled or not.
You really should be able to run your memory on turbo setting.. it just tightens up some secondary timings.

According to your testing you dont seem to be getting any memory voltage drop from what you set in bios,I get approx .02V but that could be due to psu /memory type etc.

Thats all I can think of atm.
 
@kick!
Sorry ,was mistaken post above, i did enable LLC but forgot change the list. today i changed any suggestion from you, but still not luck for any differance setting. I put another extra fan blow straight to where the drams seat, but seams nothing happen. Thanks for your help.
 
CPU Reference..........................:0.8050V [Auto] What are the options here?

use x63 or x67 if those are the options.

and may be up Dram to 2.2v since its spec call for 2.1~2.3v
 
can not get stable over 443MHz.
CPU Reference............:0.8050v[Auto] Option are:.832/.850/.873/.893
Up Vdram from 2.1 through 2.3 still no luck.
