trying to OC my E2140

Jacky-Boy16 · 7 Sep 2009 at 16:07

Here's the build I have at the moment.

Intel Core 2 Duo E2140 "LGA775 Conroe" 1.60GHz (800FSB) - Retail

Abit IP-95 Micro ATX (Socket 775) PCI-Express DDR2 Motherboard

2GB DDR2 PC2-4200

OcUK ATI Radeon HD 3850 Pro 512MB GDDR3 TV-Out/Dual DVI (PCI-Express) - Retail

500W Huntkey PSU

Arctic Cooling Freezer 7 Pro CPU Cooler

I have caved into pressure and decided to try my hand at OCing this puppy.

I've checked out a few tuts and things and gone into my BIOS. I have the option to change my FSB from 200mhz up to 350mhz.
My CPU multiplier is 8 at the moment (and can't be changed), so my CPU is at 1.6ghz at the moment.

As I raise my FSB, this will affect the memory too wont it, but I dont have the option to change the RAM divider.

All i have is this option DRAM frequency, which can be set to auto, 333mhz, 400mhz or 533mhz

but I'm using PC2-4200 RAM so shouldnt this be 266mhz?

As I'm sure you've accertained I'm a complete overclocking noob, so any help would be greatly appreciated.

Ok, first thing id so is up the FSB to 266Mhz ( 1066 on some boards ). This is a speed your mobo should easily handle and give you 2.1Ghz.

If you then set your RAM to run 1:2 ( option in the BIOS ) then it will be at its proper speed of 533Mhz

Any more of an overclock is going to be held back by your current memory

ok cheers buddy i'll give that a go

hmmm I can't seem to find that RAM 1:2 setting in my BIOS.

I have DRAM Timing
which consists of DRAM Cas Latency 3.0/5, 2.5/4, 2.0/3, 1.5/2
and DRAM Bank Interleave 2-way, 4-way, 8-way or disabled

There don't seem to be many options at all in my BIOS

any ideas what it could be?

Short of buying a new motherboard and ram you have'nt much chance of getting the best out of your E2140. This is the problem with bargain basement motherboards. It's a shame as the E2000 series are good clockers. I have had a E2140 prime stable at 3.6Ghz!!

wow so overclocking just aint possible on this particular motherboard, that sucks

I don't suppose anyone can suggest a good micro ATX motherboard for the E2140 that would overclock well, I may have to invest in one in the future if it's not too much

I remember the reason I went with this mobo in the first place was that it was micro ATX and I didnt have a lot of choice
