Guest pedro Posted November 6, 2006 Posted November 6, 2006 I've spent all day reading THunDA's excellent overclocking thread. Congratulations to anyone and everyone involved in its production. It's been very helpful indeed. I'm at the stage where I'm testing out how much beef my CPU has (i.e. right at the beginning of the process). I've decided to take the approach of gently, gently so I'm using a vcore of 1.40V as opposed to jumping right in at, say, 1.60V and I've only pushed the FSB up to 215 and am now testing at 230. I don't want a real heavy overclock - I just want to learn how it's all done. I'm now running SuperPi 32M as per instructions. I'm measuring the temps using Smartguardian are they're looking fine (CPU = 30 degrees, chipset = 40 degrees). What I'd like to know is: a) What, exactly, am I testing here? Is it the upper limit for my CPU in terms of GHz? B) Should I be using 'aggressive' RAM timings whilst testing the CPU in this way? I.e. 2-2-2-5 with a vdimm of 2.90V. c) Is 2.90V the correct vdimm anyway for my RAM? d) Slightly off-topic: What is maximum payload size and should it be set at 4096? Thanks in advance! Pedro.

ollietwinam Posted November 6, 2006 Posted November 6, 2006 a) You shouldn't be stressing the CPU with SuperPi, use Prime for 8 hours or more... B) You could leave your RAM timings like that, but it may be beneficial to loosen them up and put them on a divider, so you know that the RAM isn't holding your overclocking back Sorry, don't know the answer to c), I'm sure a quick search on Google would get you your answer though...

Guest pedro Posted November 6, 2006 Posted November 6, 2006 Thanks ollietwinam but I'm just following THunDA's instructions as closely as I can. That's why I'm running SuperPi 32M after each increase in FSB. I'm now almost finished testing at 230 and the temps are still as low as they were with 215 (& 200 for that matter). Looks good so far. Anyone know an approximate cut-off point I should be expecting? 250? 275? 567? :tooth: Quote Share this post Link to post Share on other sites More sharing options...
red930 Posted November 6, 2006 Posted November 6, 2006 I don't know for that particular processor, but I normally use 8M when finding the max as its faster. When you get an error and you don't want to increase the voltage any more, back it down a bit and try the 32M. If it passes that, then give Prime a shot. It might fail instantly even if it passed 32M, so back it down a bit more and try again. Just watch your temps and you'll be fine. Have fun clocking!

Guest pedro Posted November 6, 2006 Posted November 6, 2006 Well, I passed 215 and 230 no problems at vcore 1.40V. Then I tried for 250 at the same vcore but didn't have any luck - I got a blue screen. :tooth: So now I've bumped the vcore up to 1.50V and am testing at 250 FSB. I realize this isn't the right way to do things but I'm a lazy guy. I'd be very happy if I pass SuperPi 32M at 250 FSB. A nice even number. The CPU temp (according to Smartguardian is now hovering around 33 degrees). It's quite addictive this overclocking business!

red930 Posted November 6, 2006 Posted November 6, 2006 Keep in mind your computer isn't necessarily stable even if you pass 32M - it just isn't nearly as taxing as Prime for 8+ hours. Quote Share this post Link to post Share on other sites More sharing options...
