My Overclocking Begins - E8500 and GTX 260

Hey,

I am doing an overclock with my newly upgraded system, here are my components:

Gigabyte GA-965P-DS3P - rev 3.3 - BIOS version F6
Intel Core 2 Duo E8500
EVGA GTX 260
OCZ 2GB PC2-6400C4 Dual Channel Platinum Revision 2 XTC Series
Hiper Type-R 580W

I also want to O/C my GFX card, and I have installed the "EVGA Precision" utility, but I find it a little difficult to determine what settings do and don't work with it, any advice on that would also be welcome.

Peace,
nub

x9 | 450 | 1.28125 | DDR Overvoltage +0.05 | Boots, doesn't BSOD but some instability issues
x9 | 450 | 1.29375 | Boots, same instability
x9 | 450 | 1.29375 | MCH/FSB +0.1V | Still unstable
x9 | 440 | 1.29375 | Stable!

x9 | 450 | 1.29375 | MCH/FSB Increase to +0.15V | PC Restarts itself
x9 | 450 | 1.29375 | MCH/FSB Increase to +0.2V | BSOD

x9 | 450 | 1.3 | DDR +0.2 V | PC Restarts itself ahhhhh
x9 | 450 | 1.3125 | Stable!? (15 mins of Prime95 and is fine, good enough to start O/Cing some more for me

Load temps seem to be ~46-49 C atm

These were just a few early attempts at x9.5 multiplier, I have gone back to x9 for the time being

x9.5 | 440 | 1.29375 | BSOD's on Windows Loading Screen
x9.5 | 440 | 1.300 | Same as above
x9.5 | 440 | 1.30625 | Gets past the loading screen, then PC just restarts itself
x9.5 | 440 | 1.3125 | I get to my desktop, then BSOD
x9.5 | 440 | 1.318 | I get to my desktop for longer, and start running Prime95, PC restarts itself again

What will I need to give my system to run at x9.5 multiplier? Will I need to give it another big VCore boost?

Have you tried upping your northbridge voltages or anything else like that? You may need to raise your NB a bit higher as the FSB goes up, with quads the clock is quite dependant on the NB voltage but I am not sure how it affects it being a Core 2 Duo

Hey, I have a "FSB Overvoltage" and "MCH Overvoltage" options in my BIOS, which one of those is the Northbridge?

I have them both currently set at +0.1V

Hmmm, I am unsure. I just had a quick flick through the manual online and there's not much information for either of them.

I'd imaging the FSB overvoltage is the VTT and there's something in there that is called system voltage that I would imagine is the northbridge voltage. However I wouldn't be 100% sure in order to offer any advise on which one to riase and by how much (since most of my experience is with clocking Quads too).

Have a scan round the net to see if there are any reviews for the board and see what they did to overclock and see if they offer any explanation. It looks like the board isn't really designed to be a great overclocker anyway and so that might limit what you can do with it.
 
Haha, thanks to my new monitor I now play at 1024*768 ;]

And thanks but yes, I have already disabled those options.

I am going to try upping my DDR voltage, it is only set at +0.05 atm, and I believe my RAM is rated up to 2.0 V.

In the product description it says this: (what does it mean?)

- 1.9-2.0 Volts
- 2.2V EVP**

Edit:

OK, only means I can clock it to 2.2V without voiding the RAM's warranty.

I would loosen the timings on your ram, try it at 5-5-5-15 and see if it is any more stable.

OK, I will loosen the timings to 5-5-5-15 and up the FSB to 460. Will see what the results are.

OK UPDATE:

Loosening the timings and upping the FSB by 10 to 460 causes my system to be unstable.

UPDATE 2:

I changed my RAM timings back to 4-4-4-15, and upped the VCore to 1.35 and it now seems stable at 460! Whoo!

OK, not quite, prime95 isn't perfect, will up the Volts a little / loosen the timings more and see

voltages

Just a quick one, I read about northbride and ram voltages, am stable at 3.88 as sig but northbridge and ram are both auto, so how do I knowwhat voltage is being used as in bios you can set what you want.
So where do you look or what software do you use?
Thanks in advance
