I have used 1.6 on the MCH, and Ive been getting freezes in 3dmark testing, the NB feels real HOT. Im gonna try having a fan blow on it and see if that helps. Of course the freezing could be due to something else, only time and testing will tell.

Hm. Well, even if the NB was fine I don't think 1.7 vcore on air would be nice lol

Sorry guys, must've missed page 175 and 176 LOL

i used till 1,76 on air for my 4905 benches no problem with a fan over it and covered by the plate still

Holy Crap, Really Andressergio! Great to hear...with the NB plate still on?
heh Im still waiting on your templtes for 4.7-4.9Ghz, Ive been getting some freezes when 3dmark testing at 4.7

Sorry man, didnt get one, Ive been checkin by In box

I have been able to hone all my settings in now. I managed to get my system to be as stable as it can be using Intelburntest. I turned up my FSB Term to a hefty 1.44 with a gtl of .83 or .84 to get rid of the CPU acting slow when firing up Intelburntest after the PC has been shut down all day. I also managed to get my best 3DMark Vantage score for my self ever as well. I managed to pull off a score of 17719 .

Here is what my bandwidth is with Everest as well. This is the best I have been able to get this board to do in Everest as well, at this speed that is.

Good info, thanks for taking the time.

I just posted this in the Q9550 thread and figured I would post it here to help people out with tweaking their BIOS settings.

If you can see what the GFlops that your CPU is putting out with Linx, or use Intelburntest which I know you can see the GFLops the CPU is pushing in that program "I just haven't used Linx mind you". You will be able to probably see that your FSB Term is set to low and your GFlops being put out by the CPU when cold or when it has been shut down all night or all day, are probably half of what they should be with your chip.

I am pushing 58.5 GFlops with my CPU @ 490 x 8.5 @ 1.296v under load, this is with utilizing 3084MBs of my Ram~ for the test and the test finish in around 86s a piece~. I had noticed this because when booting my system cold from being shut down all day or all night, I noticed that when running Intelburntest the GFlops being put out by my CPU were half of what they are when the system has been warmed up or after being rebooted a few times because of me tweaking settings. You can also use it to fine tune your GTL settings as well.

I noticed that if the GTLs are off then two of the cores on the CPU will get hotter then the other two while running Intelburntest or all cores will not get hot enough. This can significantly cut time you spend tweaking these settings because you don't have to finish the test you can just go ahead and stop the test reboot and tweak some more until you see the temps are even and about the right temperature under load taking in to consideration your cooling ofcourse.

Then once you think you have the cores hitting good temps and evenly for that matter, let the test finish and see what the GFlops being pushed out are and if the time finished is fast enough as well. If you get everything set just right BIOS setting wise, all cores will stay about the same temperature all the way through the test nice and stable like. I just caught on to this and was able to tweak mine to perfection landing me the following.

3DMark Vantage Score 17719

I had to set my FSB Term to 1.44 with a GTL Reference of .84 to get everything to act correctly when first firing my PC up from being shut down all night or all day and the results speak for them selves. Hope this helps people because if I had known this awhile ago I could have saved my self some serious time tweaking BIOS settings.


I can post my BIOS settings later tonight if any one likes. I am work right now though so, I will have to wait until I get off work and home from my friends wedding tonight to do it.

nkresho, it's only wrong monitoring, use DMM to measure.

[nkresho]

Where's the measurement point? Did I miss it earlier in the thread?

awesome, thanks.

For reference in case anyone else was wondering too.

[truehighroller]

I think I found my new spot. It tested stable but, I will keep testing it to make sure.

Man thats awesome, I just tried to squeeze 1188 out of my RAM, and I get errors in memtest86 no matter what I change.

[rubber5]

hi guys i have found out why my cpu would not go over 3.5 .
It was the cpu tremanation was low
but the next problem is i dont know what a (safe temp) will be using intel burn test for 45nm prossesors
prime 95 seems to give me about the same temps under load

if i use 1.35volts@ 3.8ghz wanted 4.0ghz the temp shoots up to 90c in a blink of an eye at 3.7 the temps are hitting 85c and i dont know what to do
ps i know i can get it stable but the temps worry me

please guys what would you do in my case

specks again

ep45-ud3r
q9450@3.5 with true @1.175volts (bios)120 (silenx 120mm 90cfm fan push pull)

ocz reaper 1066@1055
asus gtx 280 (no oc) gets to hot as it is
enermax galexy 1000watt psu

thanks again if anyone can help

If I set my FSB Term any higher then 1.42 it errors out, or it is the NB voltage if I go over 1.52 one of the two. All I know is that it is stable as a rock here. These are the settings I was using for 490 x 8.5 as well I will add.


@Rubber

What cooling method are you using air? If so what cooler? Try my settings listed above maybe, if your cooling can handle it.

[phsinc1]

@truehighroller, what does your CPU Ref and MCH Ref shows when you set 1.200v Termination?

Mine likes to be set at around .88, so far that has been the sweet spot for all my FSB Term voltages that I set 1.32 and above. My NB voltage changed a little though a couple of times depending on what voltage I set it to but has been roughly between .88 - .92. I think that every CPU differs though and chipset for that matter. I will go look for you though when it is set to 1.20. BRB


Edit:

I just looked and when I set it to 1.2 it sets itself to .745 but, I know for a fact that my CPU liked .63 when at this setting.

0.745 means your GTL is @ 0.62 [0.745/1.200], I think it should be 0.760 which will give 0.633, you can check this values with ET6

What? No, I am saying that my, CPU Reference, likes to be set at .63V, when, the FSB Term is set to 1.20V. That is my stable spot for my, CPU. Every CPU is different a little. Also I will add that as you are moving up in speed and FSB Term, the spot changes a little at a time but, again every CPU is different so take that with a grain of salt.

truehighroller: I tried ur settings, hoping I missed a setting relating to my RAM (clock skews, DDR write training, MCH volt), and I still get errors (2errors@6min mark), thanks for posting ur settings though. I might be getting these errors bc my NB temp is getting too high...it feels very hot to the touch. I still havent modded the NB in any way, not even a fan.

Can some of the experienced guys chime in with the importance of adding cooling to the NB, and at what voltage u should add a fan...mine is at complete stock. How important is it too have air cooling the NB?

Viper i have it stock and an Antec Spot Cooler pointing the NB and the GSKILLS...

Mine doesnt even feel warm my ambient is 21+ C, on summer it will be hotter for sure, im using 1,46MCH 24/7 and benched to 1,78MCH

Cheers

Up to 1.78 with just a fan blowing over it?

BTW: Sergio, U havent responded to my PM

[Hoss331]

I use 1.40mch for my 24/7 at 500*9/1250 and when I had the stock heatsink on it would get pretty hot when priming even with a fan on it. I also noticed that since the first ram stick is so damn close to the nb heatsink it would get alot warmer than the second stick. I ended up getting an EK 5 waterblock for the NB which took out alot of heat and keeps it away from the ram which stay at even temps now. If I were you I would atleast pull the blue cover plate off the nb and put a fan on the heatsink and ram.
