I'll presume you're using the stock cooler. Fill your specs in in the system area of the User Control Panel?

Each processor is different. Use the Intel Spec Finder to find what Intel says your CPU can take. The E5200 chips Intel says shouldn't go over 74.1*C to maintain CPU life at reasonable levels.

You really need a better cooler than the stock one for overclocking. Either way checking that the heatsink has good contact with the CPU is a good idea.

However, I'll guess that that overclock was just multiplier being raised - leaving the CPU on automatic Vcore. Most motherboards vastly overdo the amount of Vcore needed to keep a CPU stable when overclocked if left to their own devices. Lowering Vcore (while keeping CPU stable, obviously) will help bring temps down a bit too.
Thanks, for the reply.

I am using the Rosewill RCX-Z775-EX cooler

I had the CPU voltage config set to auto and it was running at 1.6v

I dropped the voltage to 1.4 and kept notching up a step until I became stable at 1.4875v.

I am now running at 45c Idle and 72c at full load

Is 72c too hot?

Also I couldn't get past bios with a FSB over 300. Is this a limitation of my MBO or CPU?

Thanks!!!

THAT is way way way too high a voltage. I can get to 4.5GHz (not stable) with that voltage. You shouldn't need much more than 1.3v for that overclock.

Make sure your RAM is running BELOW stock speeds and is at its right voltage and latencies.

Lock your pci frequency to 100 and boost your FSB termination voltage (or VTT) up 2 notches. Increase your NB voltage 2 notches as well. Then try bringing your Vcore up from about 1.25v

Do you have a CPU-z validation for some more details on your processor and mobo and RAM?

Well, the validation is indeed the highest that it can boot as well. Strange, innit?

It is perfect till 350X12.5, after that it may or may not boot even 351X12.5.
383.5X12.5 was achieved with a lot of patience, 1.6V in the bios (1.54V actual), numerous reboots, several 120MM fans, Clockgen and some luck.

Might get one of the DDR3 P45 mobos and some ram just for the fun of doing this. Any recommendations?

I am using the M.I.T. config panel in bios. Here are my voltage adjustment options:

DDR2 Over Voltage Control [Normal] [+.1v][+.2v][+.3v]
PCI-e Over Voltage Control [Normal] [+.1v][+.2v][+.3v]
FSB Over Voltage Control [Normal] [+.1v][+.2v][+.3v]
G(MCH) Over Voltage Control [Normal] [+.1v][+.2v][+.3v]

CPU Voltage Control allows for intervals from 1.2v-1.7v or so with a normal vCore of 1.25v

Which of these options is the NB voltage?

When you say two notches do you mean [+.2v]?

Current CPU-z validation

thanks!

FSB i think. and yea 1.6v is a deathly voltage. i recently got mine to 3450 without any added voltage, and when using my friends ram, i got it to 3900 with only 1.34 voltage. mine is R0 stepping.
post #4296 of 4653
As 8800 said its the FSB over voltage control, and yes bump it up to +0.2v, then when you get it stable you can then experiment with dropping the voltages. I havent even had my chip up to 1.456v before, try and keep it under 1.3625v as this is the chips 24/7 max safe operation voltage, and 1.45v is (supposedly) maximum safe voltage.

Guys, can you help with my E5200. I can't put the damn thing over 3.2 because I seem to have very high vcore for it. Now it is running at 3.0ghz stable on 1.288V (below this it is all unstable, booting failure, restarts at OCCT) which is a true misery as I know how much this thing can take up
http://valid.canardpc.com/show_oc.php?id=1130123

So I've tried 3.6GHz and it even doesn't boot Windows with voltage below 1.35 set in BIOS! With vcore set to 1.43 OCCT still gives ERRORS and my last attempt was 1.47(cpuz!) which resulted in 70c on the cores and I gave up
Total FAIL. I dunno what's wrong why voltage is so high for that freq, my run was 300x12, rated fsb 1200. DRAM freq was set to 800mhz and DRAM voltage AUTO. My MB is ASUS P5K SE and the guy who I took it from says it has a vdrop mod. Any suggestions are welcome since I don't have any clue on this...

Try reducing your RAM speed to 1:1 so you eliminate RAM from the equation.

^^this

And...
make sure you set your RAM settings (like voltage and timings) manually.

Give your NB voltage and FSB termination voltage a bump or two. It shouldn't really need it but it might be necessary.

Tried 1:1 and same crap. It gives errors on 3450mhz with 1.36V. And my RAM is pc2 8500 or whatever was the 1066mhz one kingston hyperx. So even now running on 1066 it should go on it's stock voltage so I didn't mess anything there. Dunno why cpu-z says it is pc 6400. So screw it. every time I buy ASUS mb I swear it is my last and that was for real now. Piece of ****, overclocking abilities - MY ASS
