Started Overclocking but didn't get far!

post #1 of 12
Thread Starter 
Hi Everyone
I have been slowly increasing the FSB on start up all week just around 5 or 10MHz. I reached the dizzy heights of 1390 and the computer posted, ran windows for 20 seconds and I clicked on explorer and it flashed a blue screen for an instant but never had time to read, then shut down.

The temperatures are all cool as the machine has not run for more than a minute.

I had to clear the CMOS to get the machine to post, before I did that I could only enter the bios and move the cursor to the tweeker menu and it would freeze, sometimes I could not even get that far.

I ran it all day yesterday at 1380 with no problems but at these settings I wouldn't say I am stressing out the system!

With it being a new build, I removed the memory and the 8800GT and the Asus sound card and re-seated all items 4 or 5 times to make sure I had a good connection and swapped the memory modules.

I am now setup back to Stock settings but with all the bios recommendations as suggested in the sticky forum post for this board. see system info

When I first started this computer last week I thought it hesitated just a little before posting to the logo screen normally a computer would fly straight up to speed without hesitating, to me I thought this could be a Memory module problem because my old system give simular indications when I tried to upgrade the memory, the msi board would not accept any new memory, tried 3 different makes, anyway the memory I am using is on this board is on ASUS list so I cannot say this is the fault.

Just one more thing the FSB Multi on this board goes up to 50 so it could set at 8 from 7.
I am just a little concerned that other folk are talking about this CPU running at 3.3GHz how on earth will this build reach that.
I will have to try upping the settings again to see if anything has been seated better but I think I am clutching at straws.
Any help would be gratefully appreciated
cheers
Forgot to mention that I have ran 3dmark06 at 20% extra using Ai booster last week and got a score of 10800 but the computer took 3 restarts to get going again so I returned settings to stock.

Download CPU-Z and use that to check CPU speed and memory speed/latencies.

Have you changed your voltages for your cpu and nb and sb?
And no you cant change the multi upwards on that cpu, only down. Those settings are for the extreme cpu's with unlocked multi's.
You should be able to get some good results from that mobo/cpu/gpu combo.

Hi cptjharkness
I have just upped the FSB to 1400 on this restart and I am running ok cpu at 2.45 MHz
will try to restart soon, cos thats where my problems start.
The computer just does not want to reboot, mind you that was before I reseated all the components. Here are the voltage settings , vCore1.35v /NB 1.35 / SB 1.5v / CPU VTT 1.55v

I have just ran the 3Dmark06 and scored 10565 on standard settings.
Note! the cpu tests red valley cpu test1 0.7 FPS & CPUtest2 1.13 FPS giving a CPU score of 2222.
Is this normal do you think for a 2.3GHz cpu.
seems a bit rubbish to me. I should have maybe gone for a higher GHz single core do you think.
The reason I went for this cpu was, everyone was clocking them to over 3.00 with ease.
But Not me by the looks of things.
going to try a restart now maybe gone for a while.....lol

Rebooted OK will try increased FSB soon.

Make sure that you read the overclocking guide on this forum for the P5N32-E SLI and turn off all the settings that couuld interfere with your overclock - there are a lot of them.

CPU VTT seems a little high, although that should not be the cause of your problem. I see looking at the Corsair website that the voltage spec on these DIMMS is 1.9v. From memory, this board volts at 1.8v on auto settings, so you need to make sure that your vdimm is set explicitly to the correct value (verify the setting so you don't cook your RAM). If the vdimm voltage is too low, your machine will likely fail to post or crap out early in the boot process.

Next I would suggest that you drop the multiplier two notches to eliminate the CPU as the cause of the instability. Also set your DRAM:FSB to synced and linked, as some memory dividers are pretty unstable. Once you have done this, start increasing the FSB in small increments. If it gets unstable, up the NB voltage slightly. Keep your RAM timings on stock settings throughout the process. You can tweak them when you have the FSB and CPU stable.

At some stage, you will most likely need to increase the NB voltage. You are probably going to need 1.4v for the NB when (if) you hit a 400MHz QDR, although you are some way off that.

Once you have found your maximum FSB, drop it back down to stock, reset your CPU multiplier to default, and then start increasing the FSB. If it gets unstable, you know it is the CPU that is causing it, so up the voltage slightly. The CPU will have a fairly linear response up to a certain point, so don't dial in silly voltages.

Hi Complexlogic
Will try your logical method will get back soon as
cheers for the help & advice everyone
Edit::: I checked the voltage specs in the Bios for the dimms and it is set manually on 1.9v but CPU-Z reads 1.8v ?
I have also lowered the CPU-VTT to 1.45v.
Been testing the FSB overclocking again before I try lowering the Multi and I am running at 1450
thats 2.7MHz and its booting up Ok and running fine will see how far it goes.

You can set the voltage in the BIOS, but you can't determine what the correct memory voltage should be. That's part of the specs for the memory sticks, whioch should be available on the memory manufacturer's website.

...or did I misunderstand you?

sorry that was my fault I should have said "settings in the Bios" not specs. The memory is tested at 1.9v by corsair.
Anyway I have the cpu running at 2.7gig (FSB1550) and its ok, took it up to 1600 and it froze in windows ( Temp ok 37c ), took it back down to 1550 for now. Will try Complexlogics method of lowering the multi and upping the FSB soon as I have time.
cheers
