Man; I must be honest, I am very puzzled over this and running out of ideas. It sure couldn't hurt to give danno's suggestions a try.

I never did find any info in regards to possible issues running a 2GB video card...let alone 2 of them...on the 790i MoBo.

I do know that everyone I have communicated with on here, that has an Extreme CPU, has had issues getting things to run correctly.

Well what I learned from u guys, extreme chips are more complicated then normal, I'll give a try danno's suggestion, if it won't work I'll stay on default, guess there is no luck 4me to have OC system stable :) like we say in Russia "if your hands grow not from a right place, better stay default" ;-)

jeffreyham

That is good.

Is it possible for you to try a different GFX card to see if the same issues happen on it? Do you have an old spare or can you borrow one from a friend?

I have one XFX 8800 Ultra ... should I run it on OC system ? 1800 or 1600 FSB ?

jeffreyham

Try it on both. Your system should have no problem at all running stable at 1800MHz.

ok, I'll try it tomorrow and post back

thank you !!!

jeffreyham

Allright man....I'll be looking forward to knowing your results.

You are welcome, my friend....have a good one.

Hey man!
sorry for being out for so long, had some work ...
about my stability ... NOTHING :(
Guess I'm damned with this chip :(

Hello guys

First I'm sorry for my English

I'm trying to get stable 3.6 at least (donno about 3.8 yet)
Well here is what I got

LinX 0.6.4 - passed 20 tests without errors, 41 min 34 sec
OCCT 3.1.0 - passed one hour, priority normal, matrix (middle), no errors
Prime95 v.25.11 build 2 64bit - 11 hours, In-place large FFT's (maximum heat, power consumption, some RAM tested), Advanced -  Round off checking CHECKED

Temps were measured with Core Temp 0.99.7, under load 66-69 on all cores
Temps idle - Core 0 - 47; Core 1 - 45; Core 2 - 44; Core 3 - 44; SPP - 44; MCP - 32

guess its stable except games, I got freezes after playing every 10-15 min, then Alt+Tab and back, and its normal again

Hope for your advice

Hi guys just had to put in my 2cents as im still waiting on my 2nd RMA'd 9800GX2 and have nothing else better to do..

Seems to me your temps are a little high for idle at 3.6.. Im on air and i idle at 35c to 40c, 40 to 45 across the board on a hot day.. Load temps never see 73c with IBT 20 passes at max setting.. Your now going for 4Ghz on 1800 Mhz FSB? Im sure your load temps are going crazy now, what are they BTW? You guys ever think heat at this point might be an issue? Im not 100% sure but even lowering the multi on the CPU but still pumping 1800MHZ threw it still raises heat..

What kind of CPU cooler are you using and again, what are your 100% load temps at 1800MHZ FSB??

set your FSB to 1575 and check stability.

Hey man...I have your system, kinda. Need some tips? PM me!
@ 3.8 I had max load prime95 62-64 during the Hot and humid  summer
Idle was 28-32,  each core within 1-2 deg of that with my H50.

Welcome back, Alex!!! I sent you a PM reply.
 
Those MAX Load temps really, are not that bad. Maybe Peter Northbridge will have some helpful input for you.

What I would merely suggest is setting your FSB to 1800, work with an 8 multi. 9, you're going too far, will require over 1.5Vcore, your temps will obviously be higher.  That would put you in a stable spot almost off the bat, having your Ram and FSB @ 1:1 is butter, you can do that, presumeably, so, give it a try.  maybe boost the volts to your ram, you will be running them @ their limit.  That's 3.6GHz there, you won't really need much Vcore for that, maybe just some more Voltage on the FSB and SPP. Try 1.45Vcore, link & sync your RAM, manually set the timing, P1 & P2 enabled as well. That's a simple overclock to 3.6, however your FSB, which effects system performance the most, will be up from 1333 to 1800. There will be a noticeable performance increase from that and you should be able to pass all the prime tests you want @ good temps. Setup prime95 to do a custom test, on the bottom right, set the size to half your RAM, say 2048, so you can still use your system while it's testing and not have it lock up.  Give that a try, if you like..any other settings you need to apply have already been covered, but if you need to , ask away!
 

Something else you may want to try, went thru the posts to see if anyone suggessted it....Do a clean install of your O/s @ the default hardware settings, 3.0, 1333, ram at stock...put everything on auto if you must...install windows. Install CPU-Z, prime95, everest or HW monitor, set your TJ max to 90deg. c within either of the temp. monitoring progs. Install your chipset drivers, video card drivers, get all the windows updates, turn off UAC, set the power management settings within windows so the PC wont goto sleep or hibernate......Then start there. Do this on a seprated HDD if you got one, make a dedicated O/S for overclocking. Dont put anything else on it other than what you need to run windows and stability/temp tests. Then goto your bios and start ye olde overclock. Just another way to eliminate any other possibilities that will give you  a BSOD or something. Theere are lots of other benefits of having a dual boot PC or two O/S choices so it's generally a good idea regardless of what you're doing.

**System Voltages**

EVGA VDroop Control [Without VDroop]
CPU Core – 1.5000 change to 1.46 
CPU FSB – 1.350V change to 1.425 - You're up in the range of your max FSB @ 1800, so having the FSB up near where intel says it's the max is a good plan.  
Memory – 1.800V  change to 1.9 - You will be using your RAM @ it's full potential, if you have a moderate amount of airflow over your RAM, this small Voltage increase will not kill it, of course I'm not giving you a personal warranty, either. :P
nForce SPP – 1.37V change to 1.42, if you pass tests, we will try to lower this after
nForce MCP – 1.550V leave this, seems adequate
CPU PLL [Auto] 1.5V leave this as well, just put in the value manually.


GTLVREF Lane 0 [Auto]  +75mv  set to 0
GTLVREF Lane 1 [Auto]  +50mv set to 0
GTLVREF Lane 2 [Auto]  +00mv  set to + 50mv
GTLVREF Lane 3 [Auto]  +00mv  set to + 50 mv
The GTLVREF will be tuned a bit later, just manually set them to this for starters...once prime 95 is running properly, you can tailor it a little to get core 0 or core 1 to pass first..this is just a quick setup to get you to a stable 3.6, 450 * 8, 1800 FSB.  Should be very easily obtainable with your system.


So...aside from your RAM being different, your timings will be a little off of mine, your setup will be identical to mine, you should have stability here. 3.6ghz, 1800FSB. Put both your Vid cards in, not the physX card, dont overclock them, just do the drivers Do your stress testing on your new O/S and see where that takes you. .  Basically overclock with the bare minimum you need to have your system fully functional. Then do your add ons,  PhysX card, sound card, whatever you have. . Overclock your cards to your liking..I use the same as you, MSI afterburner and the EVGA OCCT to test. Once you have all your hardware where you want it..then do all your software. Sound like a plan? You will be starting over from scratch with this method but during the process of you doing all this, you will also be able to identify what it is that's holding you back/causing BSOD by doing it all in steps. I'd recommend doing it all with one stick of ram and one vid card but really, you're not going for a record OC, your hardware should take it. 

if you succeed with this, the next step will be to back off your voltages in small increments to lower your temps, etc....Keep me posted, tell me if you get into windows and prime95......When prime95 is running, use the custom test like I said, using half your available memory....If it fails, write down which worker stopped first, you might be able to get away with boosting the GTLVref on that particular Core <which is the worker> a few steps, or just boost the vcore one step. If you find yourself passing tests...Let's hope!....write down the "firing order" of your processor...which core finishes first...after 6 hours, core 0 does 250 tests, core 1 does 236, etc...Try to trim out the GTLVref up or down to get Core 0 or Core 1 to finish first then try to to get Core 2 and Core 3 to finish third and fourth. Maybe do a test for an hour just to get a glimpse of which core is doing the most tests and trim the GTLVref before you do your final 12-24hr test. You'll never get them all to work in unicin or like always 0,1,2,3. But you do want to try to get it at least close. You won't have a 5ghz record breaker but you will have a very snappy quad core hopefully after this is done, or a bill for a new PC. lol. I'm just building my new one, got the last Classified 3 E770 2 weeks ago from EVGA, getting an i7950, the 580 <yay>, 12GB corsair dominator 2000, not sure bout cooling yet tho. So, I'll be retiring/beating the #$%& out of this rig soon so if you want to know the limits of this hardware combo...I might find em for you lol. Good luck!

Hey there, Alex...been a long time....hope you are doing well. No new stuff here except GFX card. I'm going to stay on my 790i until it dies before I change platforms. I hope you can still get yours stabilized.

Hello my friends!
sorry for keeping silence, so far I managed only polish a bit my H50 with russian paste GOI (special for polishing metal plates), I got thermal paste Arctic Silver CERAMIQUE for thermal interface. (too much work ) I got new PSU for full stability - Enermax Galaxy EVO 1,250W Power Supply Revolution85+.  Stock temps are:
Core 0 46C (Idle)
Core 1 43C (Idle)
Core 2 40C (Idle)
Core 3 40C (Idle)
WITHOUT VDROOP
 
next weekend I'll start OC
is this temps are normal for idle without OC ?
it  too hot at my apartment, so I think I'll put my PC on the balcony while testing in  OC, its -12C outside

Nice PSU! Good choice on the paste as well! The paste also takes 150 - 200 hours of power cycling ( 2 -3 weeks of 10 hours on per day basically ) to fully cure...your temps were pretty much on the money for what mine were right after I put new paste on mine...now I'm idling@ 32 on the hottest  core and 28 on the coldest. My motherboard temp sensor reads 29 usually....so you will see some improvement over time.  Hope the OC works!!!!!

No no, you don't have the special model. Thermal Paste takes 150-200 hours to cure so your temps will go down but not right away.  So far, I do not think you've done something wrong, without me being there, of course! :P  Does your computer have good airflow into and out of itself? Is there anything blocking the exhaust? Last time I thermal pasted my CPU, I had idle temps of around 40 per core, and they went down to  30 and sometimes less after my paste cured!

Ok here I am again
So I downloaded latest version of Prime95 v.26.5 build 5 (last updated February 22, 2011)
Did some Custom tests as you told me with half RAM (all boxes unchecked) and every time my Workers STOPPED on the 1st test ...
The following "STOPPED WORKERS" order (tried 2 times) : 3 - 2 - 4 - 1 ; 2 - 4 - 3 - 1
Then I went for BLEND test (tried 2 times), also stopped on 1st test : 3 - 2 - 4 - 1; 2 - 4 - 3 - 1 (also some times it was different)
And the only test I can run without STOPPING WORKERS is "In-place large FFT's" but here I got the following WORKER FINISH order : 2 - 4 - 3 – 1; 3 - 4 - 1 - 2 and so on. I’ve been running it for a 30-40 min already ... If you ask me about the temps, I'll answer - its cold , because I set my PC in the balcony and its -10C outside , so right now I run "In-place large FFT's" and its 51C each core under load ... I'll leave my PC there while I run tests, cause its really hot inside, about +27C, H50 won't cool the processor in such ambient temp.
