Whats wrong ?

[SwedX]

Hello guys!
Finaly been able to get my new rig so its now complet and now to some overclocing!

When I run Orthos blend test after some 30 minutes or so it hangs my comp completely and I just have to reboot!

I wonder what it can be!
I have disabeled what to disabeled in this guide from IGN!
http://pc.ign.com/articles/747/747606p2.html

My spec is!
e4300
EVGA 680 I SLI
OCZ PC2 8500 SLI 2 GB
TT 120
TJ05 Case
Thermaltake 850W PSU ( This one shold be very good )

Have big trouble to get it stable at 333*9 = 3 Ghz
That shouldent be any probs with this processor I heard and I have give it so much as 1.5 V and my memory 2.3 V and gave some more juice for the CPU FSB and Nforce SPP but still it doesent help!

Any Ideas what it can be, it driving me nuts :thumbdwn:

High Temp? mem clk too high?

[SwedX]

In TAT it shows around 60 to max 70 degrees!
Exuse me but whats clk ?

Thanks for the reply BTW.

[Tr1cK]

Have you manually set the RAM timings and have all that SLI related ram stuff turned off? Mine is 100% stable.

Thanks for the reply BTW.
Sorry, clk = Clock, or frequency. Did you set your mem to 1066 Mhz or 800 Mhz. as suggested by Tr1ck, did you set the appropriate memory timings manually?

[Xion X2]

Set your RAM speed to exactly half of your FSB.

[SwedX]

Yes I have set my memory Unlinked at its default speed 1066Mz 2-5-5-5-15
so it shouldent be a problem atlest, hope so!

Everything SLI is disabled to guys.
Strange now it has run in Orthos stress blend for 1h 15min :)
How long do you guys belive I shold run it to call it stable ?

Thanks for the input guys, very much appritiated!
BTW! Du you O/C the CPU FSB and Nforce SPP?
I dont belive I have to as my FSB is only att 333Mz but I dont know maybe I should so its now on.
CPU FSB 1.5V and Nforce SPP 1.50 the same as in the guide I refered to!

[Tr1cK]

Does Orthos work both cores over? I know I have to run 2 instances of Prime 95 to hit true 100%.

In TAT it shows around 60 to max 70 degrees!

Thanks for the reply BTW.
If you are talking in degrees C .. thats WAY to hot... you can damage the chip at anything above 60.1C

[SwedX]

Yepp it work both of the cores same time at 100%
Have run 2h 30m now so it seems to be good then :)

Now I shall just stress the CPU with the small FFTS some more couse my mem seems to be okey atleast!

I dont think temp under 70C will hurt it..annyway its the only way to get it this high im afraid.

[Tr1cK]

I really would re-do the thermal grease application on that thing. Get some Artic Silver 5 on it. Mine runs hot on this setup compared to my old mobo supposedly, but I'm still trying to figure out if it's correct in the reading now. I would declare 65 as the top limit for spike usage and 60 as the constant max.

Also, I like to use large TFTs for stressing, but that's just me.

[SwedX]

I have just the other day when I build the comp put on a slight line in the middle of the cpu Artic Silver 5 just as they say on their site so that should be okey I hope!

Okey will try to get it some lower, dont want to burn my cpu so better listen to guys, thanks :)

Will try the large TFTs as you said to.. is it even better in your opinion ?
How long do you run it to call it stable annyway in that mode ?

[Tr1cK]

BTW..what voltage are you running to that thing? Mine is at 1.34.

[Xion X2]

Yes I have set my memory Unlinked at its default speed 1066Mz 2-5-5-5-15
so it shouldent be a problem atlest, hope so!


Noooo, you didn't hear me. Don't set your RAM at "default" speed. If you're overclocking an Nvidia chipset, then you have to set your RAM at exactly half of your FSB in order for it to be stable 90+% of the time. Intel's memory controller is in the northbridge and not on-die like AMD's, so it's much more picky about this.

Set your RAM at exactly half the speed of your FSB by manually adjusting the speed in the BIOS. If your FSB's at 1600, set your RAM at 800.

I dont think temp under 70C will hurt it..annyway its the only way to get it this high im afraid.

Well Intel says the max temp for your cpu is 61.4c.
If you want to go against Intel, I won't stop you. But if you damage your cpu, you are the only one to blame.

[SwedX]

Hello guys!

Well now im a very happy man, I know what was wrong about it..I dident push then nforce SPP voltage at all..today I set it up to 1.5V and now all problems seems to be solved :D

I can now have my volt to the CPU at 1.4000, maybe even less but I settle for that for now and its only over some 50C so its cool!

My FSB voltage seems to run fine on stock setting 1.2V but when I set the SPP back to stock at 1.20 then the system hang in one minute or so!

Will now try to set the SPP at 1.30 to see if its enough.

BTW Xion. the memory hmm shouldent PC2 8500 mem go for 1066 stock. but if its not stable I will keep thet in mind, thanks!
My FSB is now at 333*4 Quad pumped = 1333 Mhz and you mean that I have to set my ram to half of that = 666 Mhz if I understand it corectly ?

Okey thanks I will keep that in mind definetly and keep it below that temp.

[SlieTheSecond]

No prob.

Heres the link http://processorfinder.intel.com/details.aspx?sSpec=SL9TB

[SwedX]

Nice thanks.. good to know atleast even tho I will not follow it ;)
If its a little over I dont care..will go quad later in the year any way.if its just stable until then i'm glad.

Update!
I can now push this nice little chip at 8*400 FSB = 3200Mhz witch was imposible to reach with the multi at 9 (356*9 = 3200mhz)..and this is good as my FSB is higher and the temp is beyond 70 at 1.475V :D

HUH? lol

Mine will clock way up there, but I don't like throwing a bunch of voltage at it and running hot etc. My PC is a little louder than a whisper right now. After having a system with 8 80mm fans constantly running, I LOVE this new setup.

[SwedX]

heheh but I dont care I just want the best performance I can get and the fans is pretty loud from the case/PSU annyway so it's okey for me.
I was hoping to reach 3.4 or so but 3.2 aint to bad eaiter I gues :D

It doesn't have anything to do with a memory problem. Yes, the memory should be able to run at stock speeds, but when you overclock an LGA775 Intel motherboard, it places extra stress on the memory controller that is located in the northbridge. Without getting too technical, while increasing your FSB it often tends to stress the chip to the point of instability. To solve this, you run your RAM at half your FSB and just reduce the timings of the RAM a little in order to compensate for the speed loss.

Run some blend tests in Orthos while surfing the web for a while and see if it freezes up. If it does, then you need to do what I said.

I could never get any of my 680i boards stable w/ an overclock until I did this.

Okey XionX2 I have now set my mem exactly as you said!
My FSB is at 1600. 400*8 = 3200Mhz had to lowered the multi to 8 couse at 9*356 = 3200 it hangs in the blend test Orthos!

And to have a little higher FSB can only be a good thing I gues :)

So I run my mem in linked/ Sync Mode at 800 Mhz just as you said and I have completed the blend stress test witch took about 2 hours, so it seems very stable now thanks mate :D
