Overclocking + More Problems - What am I capable of?

Hello Everyone

I have decided with this motherboard, I will for once see the absolute max I can overclock. With that said, I am a bit unexperienced in learning say... When my CPU is at its max, or when the voltage is at its max.

I just got done raising my voltage to 1.35v in the BIOS (However CPU-Z still reports 1.113v) and raising the CPU to 3500mhz, however upon running Orthos (And everyone else seems to be fine), Orthos reports:

Test 1, 4000 Lucas-Lehmer iterations of M19922945 using 1024K FFT length.
FATAL ERROR: Rounding was 0.5, expected less than 0.4
Hardware failure detected, consult stress.txt file.
Torture Test ran 0 minutes 14 seconds - 1 errors, 0 warnings.
Execution halted.

Which doesnt tell me much - not enough voltage? Too high already ? (doubtful) CPU is at a steady 40 degrees Celcius. Well I raised the voltage, which seemed to do absolutly nothing.

On another Note -
My Memory is rated to run @ 1066 FSB, yet if I try to run that it will pretty much instantly crash (BSOD, no explanation from the errors), thus being forced to leave it @ 800 FSB. In light of that, I have run memtest atleast 3 times overnight, so each was over 8 hours, 25+ Passes, 0 Errors. I dont know how to explain that, if it isn't fixed by next BIOS I will contact Corsair on that part unless you guys have any ideas for this problem either.

Specs:
Intel Core2Duo E6700 w/ Zalman 9700 Heatsink
ABIT IN9 32X-Max
Corsair Dominator 8500C5D
Western Digital 150GB 10,000RPM Raptor
PC Power & Cooling Silencer 750w Power Supply
 
That Orthos result is typical of not enough CPU voltage. Raise it higher, you may need 1.4V or more.

Though if you RAM doesn't run at rated speed and timings (w/CPU at stock speeds) I would definitely RMA that first.
 
Well first I am a little confused - The front box of my RAM states 1066mhz @ 2.2v, I assume thats not something technical for something less in where I enter DDR2 in my BIOS?

Oh also as far as voltages - If I were to raise my CPU to 3.8GHZ, what would be an ideal voltage?
 
For 3.8?

You'd need at least 1.5v.

What are you measuring that "constant 40'c" temperature from... I doubt you can get a 40c temp with a 9700 under load. Infact, I'm certain you could not.

Most ram can do DDR1066mhz with timings around 5-5-5-15. If you're leaving them at "auto" or stock, they might be running at less than that... Therefore causing a memory error at their rated speeds.
 
I use ABIT's uGuru tool to see my temps, my temps are fairly consistant. But why would you doubt the Zalman 9700? Whats better for air anyways (Not trying to argue with you, just interested in the best).

The crashing due to RAM was AFTER i manually set it to DDR1066, "Auto" from the BIOS would keep it at 800, which was rock solid. You sure most ram can do 1066? If so, what should mine be capable of?
 
I'm not doubting the 9700, but most people with WATER don't get that low. It's a VERY capable HSF, probably within the top 2 for brute cooling, and near the 4th for quiet/cooling ratio.

at 3500mhz I load in the mid 50's with a double Radiator and a TDX waterblock.

Use intelTAT to measure your temperatures!

Your RAM should do 1066mhz with 5-5-5-18 timings according to the Manu. specs.
 
One other thing about my overclocks - I have it set currently at a mere 3.33ghz, with the chip currently idling at ~37 degrees C, full load never goes over 50, yet I get random freezes. I left it on overnight and my monitor was blank as if the computer was off, yet the computer was on. Where do I go from here in finding out whats to blame?

Click to expand...

Sounds like bad RAM. Don't trust the uGuru software for temps either, use Intel TAT or Coretemp. Like I said run Memtest86+ for 24 hours with 100% stock, rated settings, if you cannot pass those tests it's your RAM.
 
Thats the thing though - I have run memtest multiple times, 0 errors :(. But as far as Intel TAT, everytime I try to run it gives me the error: "Error enumerating On Demand Clock Modulation support. Terminating Tool."
