OC'ing a E2180

marcus.slee · 15 Mar 2011 at 11:28

Hi,

I'm running Abit IP35-E, DualCore E2180@2ghz, Arctic Cooling Freezer 7 Pro CPU Cooler and attempting my first OC in prep of a Q6600 arriving in the post soon.

I up'd the CPU to 240x10 and ran prime95 without issues - max temps 53. when I tried to go for 266x10 the system wouldnt boot at all. I thought I'd broken it completely - but after leaving it off for 5 mins it allowed me to go into BIOS and revert to 240x10.

Is this a voltage issue? should I consider:

1. lowering the multiplier and upping CPU
2. upping voltage?

I'm nervous about fiddling with the voltage as I know that can fry the chip. Is it ok as long as the temp remains below low 60's?

If I do push it further and it gets stuck before BIOS, is there anything I can do besides waiting for it to cool completely and just hope it'll boot up so I can revert the settings??

thanks guys!

Voltage is fine up until about 1.4V with those chips (if I remember right), what's it on at the moment? I would say it most likely needs to be raised a bit more. And temperature wise, if it stays below about 65 on prime, I would be happy with that, as under normal load conditions, it wouldn't reach that anyway.

I think you need to read some guides on overclocking if you haven't already, you need to learn about bios resets, and failed boot attempts also.

As for what you have done so far, it was good in until you went from 240x10 to 266 this is a huge jump you should look to only be doing 5-10mhz steps not 25mhz steps.

there are a lot of guides on voltages read them and make up your mind where you are happy to take it to Ive pushed 1.5 through some of my chips in the past but I was happy to do that for a short period when I was benching.

Hope this helps.

voltage at present is low - 1.2 or something similiar - will check when home. I've read that my chip can get to 1.4 fine - just nervous about doing it!

- As long as I up it incrementally and monitor the temps I should be fine though right??

I've done a fair amount of reading already - was told that if i upped it too much it would just fail to boot and I could reset from the BIOS. there was nothing about failing to get to even get to BIOS

I think it's because my Pc 'double boots', i.e. fires up for 3-5 secs, turns off, then boots up properly. it seemed to get stuck on this first boot. I think this is a problem with my Mobo - was advised (on here) that it wasnt really an issue unless it bothered me (which it doesn't)

Voltage is fine up until your temps are too high, it is the later 45nm chips which you're thinking of.

My E2180 has ran for 3+ years at 300x10

My Abit IP35 always did the double-boot when the power was removed completely from the board.

Check your RAM speeds - as you increase the FSB, if you don't decrease the RAM multiplier, it'll try to run your RAM too fast.

Confused: cheers sounds promising! what's your voltage and whats your RAM multiplier?

Can't remember the voltage, it was only slightly over stock if I remember. The RAM I've got is only 800MHz, so I used whichever one gives it closest to 800!

The CPU is now in a Gigabyte GA-73PVM-S2 board doing media centre duties - but still at it's 300x10 speed.
