Overclocking ABIT IP35-E and E6750

Hi, just wondering if anyone has any experience overclocking with this board and what I can expect? A review of the board I read (after buying) said they didn't get the cpu FSB much over 350 which seems a pretty poor return.

Also can someone just confirm that I need to manually put the ram on 333 before trying to overclock? I just noticed in the BIOS when I try to set the CPU FSB to 400 (which failed to post), the boards says that involves a ram speed of 960 MHz (which obviously it won't do). That's with the ram set to SPD (which I presume is running it at 400) rather than manually setting it back to 333.

Is there anything I'm missing here regarding multipliers or anything like that? Is it just not a great board for overclocking, or do these 1333 chips not overclock as well? It's just I see lots of people with C2Ds well over 3 GHz.

I didn't really buy the bits with overclocking in mind btw, so I wouldn't be too fussed if a 350 FSB is the best I can achieve. Performance at 2.66 GH is damn good.

Cheers,
Simon.

The IP35 is a great board for overclocking. Set your RAM to 333mhz which will be a 1:1 multiplier with the CPU. Set the CPU FSB to 400 and that should give you 800mhz RAM and 3.2Ghz on the CPU. From there you can try increasing in 5mhz bumps to the FSB and see how high you can get. You'll probably need to feed the CPU a little more voltage but keep your temps in mind and test with Orthos DC to check temps.

would take of spd & set timings + volts on ram yourself
this should do 3.2ghz easy just out of box @ stock or a slight increase in cpu volts.

if u think ram holding u bak, try 5.5.5.15 & c if that works
good combo

I always thought the IP35-E was a poorer clocker compared to it's vanilla IP35 and IP35 Pro brothers.

You will need to change the Memory Ratio to 1:1 before continuing. If it's still struggling, tinker with the ICH, MCH voltages as well as CPU VTT.

Okeydokey, will try all that and report back soon, thanks

Ah there we go. 3.2 GHz (400 MHz FSB) all the way

Just running SuperPI 32M on each core simultaneously and it seems fine, CPU temp 48-50 according to ABIT EQ, coretemp showing both cores in the same region (46-50). Doesn't even seem to be running hotter than at stock TBH. Lovely stuff :cool:

Yeah I was misunderstand one of the bios settings, the memory divider set on 'auto' wasn't running 1:1, it was using 6:5 and running the ram at 800 with the cpu at stock and 960 with the CPU at 400. My fault for not looking a little closer. Ram is still on SPD btw.

I have a secondary question - CPU-Z shows a black page on the ram SPD - does that means the SPD data isn't set on the ram and therefore it might be running slacker timings than the 4-4-4-12 it's rated for?

Cheers again for the help

Simon.
