Yes....you want to test your RAM at their rated spex of 8-8-8-24-2T 1800MHz. If both sticks pass the test then, as VistaHead said, the freezing issue is probably being caused by one of the GFX cards.

I apologize, Alex...I am going to have to go offline pretty soon to run some errands but, I will be back on later...just wanted to let you know that I am not abandoning you.

OK, Man....I am not aware of the possible 2GB video card issue that you mentioned but, I will do some research on that when I get back on later and see what I can find out.

Have a good one,

Jeff
 
P.S.- You telling me that you appreciate my help is ALL the thankx that I need. Cya later. 

Hey Jeffrey,

So what I managed to do today (just got back from work, 6:23 PM) is to test two sticks of ram in black slots - no errors for 8 hours, please see the pic below.

The settings were the same as in previous post when I tried to load with 4050 Mhz:

nForce SPP <-- nForce MCP - [5 x]

**FSB & Memory Config**

At this point it is probably the chip holding you back. Reading soem other forums, some people had to switch to water and pump 1.6v into the chip for 4+ GHz. but you never know, please keep trying Jham and Vistaheads suggestions.
 
Are you using any CPU stability programs? (Prime95,  Intel Burn Test)
 
P.S. in another post a person had freezing in games only. The SSP voltage needed a bump. try the highest green voltage on the SSP and see if that gives you any stability in games.

VistaHead

So how is the PC performing?

I can boot, I can play e.g. Mafia 2 for 10-15 min with freezes, then BSOD ... even Prime95 gives BSOD when I start "Blend" test.

With the settings in the the Post #1, I pass easily 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, but not "Blend", if I start stress with "Blend", it gives error right after the start with 1-2 cores (always different cores) and then I stop the test :(

I use LinX 0.6.4; OCCT 3.1.0; Prime95 v.26.1 build 1 64-bit

i just have to say.. why would you overclock a extrem chip by uping the fsb. i just thought that if it was me.... wouldent you change the multiplyer. thats why you buy an extrem chip the multi is unlocked. just saying... what do you think.

yes and no, honestly a OC on the FSB will be more benificial than an OC on the CPU. The FSB sets the speed for the rest of the system. It is the speed at wich all of the other components "talk" to each other. Since the OP is sorta maxing out at 4.0GHz. (1800FSB/4=450,  450*9=4.05GHz) we now need to take it down a little but we would want to try and keep the 1800 FSB. The next multi down is 8 (1800/4=450, 450*8=3.6GHz)
 
This way all the components are still "talking" to each other at 450MHz.
 
Lets say you want to OC by the multi. Lets shoot for the same 3.6GHz.
 
Lets jack the multi to 12. (3600/12=300, 300*4=1200FSB) Now the whole system has been dumbed down to 300MHz with the same CPU speed of 3.6GHZ
 
 
 

Do you have time to try each card individually with the 1800MHz settings??

Gotchya. I'm starting to think that this may all boil down to your Corsair RAM "not playing nice" with your board.

 I find it  slightly peculiar that he can pass stress tests but when in game he's having stability issues. I think something else is at play here. Possibly the GPU or a driver issue?

Can you take a picture of the BSOD next time it happens?

Well, its me again, probably most of the people get bored of my problem, sorry guys ;)
Anyway, I've made some tests and they all were with freezes and BSOD's

First, I played Mafia 2, Chapter 5 with two cards, one for video - one for PhysX (cause it gives more boost then SLI) with the next settings :

**Frequency Settings**
CPU Freq, MHz – 4050
FSB Reference Clock, MHz – 1800
CPU Multiplier - [9X]
PCIe x16_1 & 16_2, MHz - 100

SPP<->MCP Ref Clock, MHz - 200

**HT Multiplier**
nForce SPP --> nForce MCP - [5 x]
nForce SPP <-- nForce MCP - [5 x]

**FSB & Memory Config**
EPP 2.0 Memory [Disabled]
FSB – Memory Clock Mode - [Linked]
FSB – Memory Ratio - [Sync Mode]
FSB (QDR), MHz - [1800]
Actual FSB (QDR), MHz - 1800
x MEM (DDR), MHz - [Linked]
Actual MEM (DDR), MHz - 1800

P1 - [Enabled]
P2 - [Enabled]

**Memory Timing Setting**

x tREF 7.8uS

**System Voltages**

GTLVREF Lane 0  +75mv
GTLVREF Lane 1  +50mv
GTLVREF Lane 2 [Auto]  +00mv
GTLVREF Lane 3 [Auto]  +00mv

And I got freezes and then BSOD maybe after 5-10 min playing

The third case is when everything on default, auto , etc.
No freezes, No BSOD's !!! Can play SLI or one for video - one for PhysX, NO PROBLEM at all


P.S.
Some how I just got couple freezes with the defaults ... whatta heck ...

P.P.S.
Set MEMORY voltage to AUTO and GTLVREF Lane 1 +20mv ... yet stable ... Mafia 2 chapter 7

P.P.P.S.
Played from 7 to 11 Chapter ... not a single freeze on defaults

ok, on your auto settings, only run the system on one card only, no SLI and no PhysX card.  run it for a while. then try your other card on it's own and see what happens.
 
 
also, i had a heck of a time with my Q6700 with FSB from 1600 to 1825.
 
so try your settings from post #38 but the CPU multiplyer at 8 and set the FSB at 1900
unlink the ram and set the memory ratio to auto, leave the ram at 1800
 
run Intel Burn Test for 20 passes at maximum.
