i have an e5300 and want to get it at 4.0ghz 24/7 (i got water cooling)

i have ddr2-800 ram 4-4-4-12

i have the ga-ep45-ud3L mobo

what should i run the multiplier and fsb at?

10x400?

would this 400 fsb cap my memory speed at 800 mhz?

is there anyway i can get more speed out of my memory?

This should be your first stop.
HOWTO: Overclock C2Q (Quads) and C2D (Duals) - Guide v1.6.1
http://www.tomshardware.com/forum/240001-29-howto-overc...

Shadow's Gigabyte motherboard OC guide:
http://www.tomshardware.co.uk/forum/page-245679_11_0.ht...
It's for an EP35-DS3L but all the Gigabyte Core2 BIOS's are similar.

Go through the guides. Then first thing you should do is go into the BIOS and change the System Memory Multiplier from AUTO to 2.00, 2.00B, or 2.00D - whichever you need to set the Memory Frequency to twice the FSB. Then when you increase the FSB, the memory clock will rise in step with it.

Warning - confusion factor between what the BIOS calls things and what CPUZ calls things. What the BIOS calls "memory frequency" is actually the memory clock. What CPUZ calls "memory frequency" is the real memory frequency, or half the memory clock - DDR2 RAM, remember? It transfers two chuncks of data each bus cycle. What you want in CPUZ is a 1:1 FSB:RAM ratio.

Overclocking memory doesn't accomplish much besides limiting your CPU overclock where the real speed comes from. Some of us discuss that here:

You may not be able to reach 4.0 GHz. This is a "YMMV" thing. The best I was able to do with my particular E5200 was 3.78 GHz. (315 MHz X 12).

Next, you have no idea if your chip can run with a 400 MHz FSB even at lower internal multipliers.

Here's a thread where I comment some BIOS settings:

i have built 4 gaming systems with e52/e53 you can get them to 4ghz but require alot more power at the moment i am still running on my gigabyte ep45t-ud3p and an e52 (first ones to be released) @3.75 since the day i bought it with just an extra .1v on the cpu using a 300mhz fsb. leave ur multiplier on auto it will then still save you power when not going flat out by idling at 1.8ghz not to mention the heat and stress on everything else if i remember rightly ur board doesnt have much in the way of heat pipes etc and the nb gets hot. the extra 250mhz isnt worth the extra bullshit. btw the asus boards dont seem to like over 3.6ghz at the same settings

Hey, videl.
Been doing this for a few years. Plus, I'm working in Saudi Arabia on a bachelor assignment and I don't have a real life. :D

Really? I'm surprised. I would have thought that a CPU with such a (relatively) low FSB would be easy to support. I mean, these are the same boards that can go past 4.0 GHz with an E8200. There's got to be something else going on. :shrug:
(We need a :shrug: smiley. :)  )
