First time overclocking and went in for the tiniest overclock on my opty 170 just to start me off (an fsb increase of only 5!) Booted into windows, ran 3d mark 05, 06 etc seems stable, however even with my zalman attached, the cpu reached 45 under load! Now surely this is too high?! Anyone got any ideas? Thanks

nope bios 'seems' to have everything else as it is, it just seems really weird. I've gone up to 2100 and its sitting contentedly at 32 idle which is what i'd expect but even now it hits mid 40's peak. I'm wondering is it anything to do with how much thermal grease i put on the cpu when installing the zalman? I did put it on 'very' thinly.
 
Just looked at the memory and its only at 175mhz and at a 2t command rate, what's going on? For a first time overclock, things are getting very weird. Edit: memory won't go back to stock either!
 
Yeah, just went into bios and resetted everything. The memory's now at 167mhz, i don't know how to put it back! help!
 
I'm not using a divider, as said in my first post its my first overclock, just went straight for increasing the fsb. I've read my fair share of overclocking guides, but haven't been able to figure out how to set up dividers on my motherboard's bios, a quick guide for my mobo on using the bios - and overclocking my cpu (see sig) would be great *hint hint* :D

Edit: Please help, I now want to just revert memory back to stock and start again but have no idea how to do it

Just put everything back to normal and tried it @ 215 fsb, got into windows and it only recorded a +50 difference in 3dmark '06 - why is it only increasing so little?!
 
I have that cooler and for those temps I would say that it isn't working properly. Have you got the Zalman FanMate on (if so get rid of it or set it to full) also, you may want to consider re-seating it if temps don't drop.

Don't just start overclocking without working things out properly. Before you started raising the FSB, you should have dropped the HT multi from 5x to 4x (can't find a pic on google). Do this now!

Second, here you should set the memclock value to 166. This is how you set the divider on your board. This gives the CPU : RAM ratio 200 : 166 - making the RAM run slower than the FSB.

Now you can raise the FSB speed. If FSB x HT multi > 1000 then you should drop the HT multi by one.

When you encounter instability, raise VCore slightly and test again. At each step up, stress test for stability and watch your temps (over 50 is getting HOTHOTHOT)
 
just reseated the 9500 and its recording a loss in idle temp of about 5 degrees! Phew i've got a little more headroom then
 
Thought there was a problem there ;)

What paste are you using - the stuff that comes with it? If your using AS5 then you can expect it to drop another degree probably as it settles in.
 
Hmm I've only just looked at your spec properly. That's a damn fine rig you've got there! You can expect to see some fine clocks out of that. If you want something to go by to see what others are getting out of that CPU you can look here. The gfx will clock nicely as well :)
 
Yeah i know :D I went for b4b and nearly everything was on this week only deals :D

Thanks for all the help but knowing me i'll be back on here crying for help in about 5 minutes!

it's now running @ 2.3ghz at 33 C idle - not too shabby (had to up the vcroe voltage a tad though)
 
Lol, told you i'd be back! It doesn't seem to be stable at any overclock. I've tried everything, running under lower memory dividers, pushing more volts through the chip - i know i'm being a pain but this is really starting to annoy me, i just want a stable overclock of around 2.4, and it should be easily acheived, what with the spec. If it's not too much of a big job can someone with experience of any of these components, give me an exact run down of what is meant to be done to overclock it to 2.4. Thanks in advance

Sorry to be going over things again but you have dropped the HT multi haven't you? Apart from this, I don't see what's going on tbh. What VCore have you taken this up to? What are the RAM timings set to?

Back on here again, the PCI frequency isn't changing as you up the FSB is it - it shouldn't be and this would be a potential cause of instability.
 
In the bios there doesn't seem to be an option to drop the ht multi only the total ht in mhz @ stock its set at 1000mhz so i assume that's at 5 x's. I took it down to 800mhz (4x's) put a 166mhz divider on the memory and upped the fsb to 220 which should be fine. However, put it on 3d mark '06 for an initial test and it rebooted, pci/agp are auto locked anyway so should be no trouble there. Nothing else was changed either.
