Nice but does Orthos really stress all four core, I think it only stress two or all four up to 50%. Let me know if i´m wrong.

Run the same with Prime95 small FFT or if blend, try custom with four instances with max memory use, it gonna make a different.

mate but radaja is running a dual core now not a quad anymore...

cheers

[andressergio]

well this morning i tried lowing the vcore down one notch
for my 9x500@4500 ddr1200 and it worked
it was at 1.356 in bios for 1.32v in windows
now it 1.350 bios still 1.32v in windows,but damn thats just great
it helped with temps by a few degrees
they were on average 47c to 50c load before
and now they are 40c to 46c load
before

nice mate im running the same setup but on the Q9650 of course different volts but i love 4500 + 1200 mems

Cheers

Thanks , my bad , I missed that, sorry radaja, great work.

Some guys surely had a good laugh, this one is on me.

[radaja]

thanks guys,its nice running 4500 ddr1200.
working on this now 4500@1.31v

Nice run radaja, nice temps too. tjmax for 45nm dualcore should be 95c though.

[Hoss331]

Hoss331 nice chip you got there!

What the VID on that Q9650?

Thanks, 1.15

I dont know if these gskills pi ddr2 900 will hold much higher , with out loosing the timing ive heard on like one forum , that these are really the gskills pi 800 just pushed harder , but for sure tommorow ill try see if theyll hold .. what kind of cooling are you using hoss331 ?

The ram should have some leeway, 461 would only be 922 and if there rated to 900 there probably the higher binned 800s. In case they wont do 922 just do a large fft run first instead of blend. Coolings in the sig.

Intel says TJ Target=100C for the 45nm Dual Core.



Intel calls this number Target TJ. They shoot for 100C but what they end up with is anybody's guess. Intel did not admit to how much error is in this number so it is somewhat useless information.

I thought TJMax was closest to 95C originally but Intel says it is closer to 100C in their presentations last year so I changed it in RealTemp.

The truth is that there is probably 10C or more of error in actual TJMax on 45nm Core 2 CPUs. Two CPUs of the same model number might have an actual TJMax that is completely different. 100C is Intel's best guess but I have no idea if that is an average value or a minimum or a maximum. Nobody knows.

That's why comparing the reported core temperature of two different uncalibrated CPUs is pointless.

[radaja]

thanks zucker2k,after a little tweaking i finally got it stable at 1.31v@4500 i raised the vtt to 1.28 and the vdimm to 2.14
cause when i first tried 1.31v i also tried vdimm at 2.12v but it failed after 27minutes
so i did some adjustment and all i have to say is this cpu awesome

[fatguy1992]

Dam thats a awesome CPU radaja - also awesome work overclocking it I wish I had a E8x00 that good.

I could do with some help trying to stabilise my system folks and see you are doing some great work here!

I am working my way up the FSB Scale, trying to be as thorough as possible with the tests to ensure stability but currently Prime95 is proving to be my Nemesis!

It passes 20x IBT Trials ok as well as OCCT 1hr Linpack and 9hrs Standard but more often than not fails Prime95 (Small & Large tested so far) or sometimes even locks the system up forcing a reboot.

My current 480FSB template (I am however testing it with CPU Vcore five steps up from default @ 1.30625V BIOS / 1.248V Windows)...

I would really appreciate some advice...D-an-W

[bluestang]

radaja and others, I have an E8500 with a VID of 1.25 (although box says 1.26 max). So, should I assume that my chip will at 9x500 like yours, but take more vcore to do it? Also, mine should run cooler than your also right? I need 1.375 in bios for 8x500fsb, so I wonder what I would need fo 9x500fsb!!!??? Does the vid value also affect the VTT need too? Thanks!

[radaja]

Dam thats a awesome CPU radaja - also awesome work overclocking it I wish I had a E8x00 that good.

thank you for your kind words,but alas me thinks the cpu did all the work
when the cpu is golden,things just seem to work
thanks again

[paul_]

I wish I had a golden CPU, my X3370, albeit a quad, struggles to stay stable at 4 GHz

Hopefully I can get this sorted after my build is done and get to at least 4.2.

Some n00b questions:
What is VID?
What is VTT and what does it directly translate to in BIOS?

I'm sure it will take a lot more Q and A before I have a properly OCed processor.

vid is the stock vcore when your cpu is at default(its what the board will set on auto vcore)you can see it in coretemp
vtt is fsb voltage termination.

[paul_]

Oh, jeez... I'm pretty sure my VID is 1.30

my E8500 had a vid of 1.25 and yes they will run cooler.i never got mine to 4500 but did get 4400 and i think it neede 1.39v for that.
not sure about vid affecting vtt.i ran my e8500 at 1.24vtt t0 1.8vtt for most of my OC's

And VTT is the CPU Termination voltage on the Gigabyte boards

[radaja]

thats right,i knew something didnt sound right when i wrote that.
thanks xzulu.

[paul_]

At this point I guess I just need to go through this thread and get a sense of how to set things up... I'll get there.

[radaja]

these threads will help out too.

Two thumbs up

[fatguy1992]

True, as my Q6600 can do 4.05GHz stable easy on 1.35vcore and it isn't fussy about everything. Not like my E5200 and E8500.

[xzulu]

thats right,i knew something didnt sound right when i wrote that.
thanks xzulu.

no problem dude

At this point I guess I just need to go through this thread and get a sense of how to set things up... I'll get there.

[LOUISSSSS]

hey i'm new to this thread.
whats the difference between 2.00D and 2.00B guys?

what exactly is the "terminal" voltage for CPU and MCH?
what about "reference"?

i'm coming from a ds3p that didn't have these options
