hey guys, just got my new setup and having some problems overclocking

Hardware:
E6750
MSI P35-Neo2-FR
2x1gb Crucial Ballistix DDR800


I'm able to get it to run at 3.4Ghz, 1:1

Here comes the problem, my system just refuses to boot up when the rams are running at DDR 900 which it's more than capable of doing.

Bios Settings:
Execute Bit Support: Disabled
Set Limit CPUID Max Val to 3 - Disabled
D.O.T Control - Disabled
Intel EIST - Disabled

CPU FSB: 450
Mulltiplier: 8
Ram Timing: 5-5-5-12
Ratio: 1:1

CPU vCore: 1.3v
Mem Voltage: 2.2v
VTT FSB Voltage: 1.3v
NB Voltage: 1.45v (It auto change to 1.45 when i set FSB at 450)
SB I/O Power: 1.8v (It auto change to 1.8v when i set FSB at 450)
SB Core: 1.05v

To make sure that it's not my cpu hitting the wall or insufficient vcore,
i've tried lowering the fsb to 300+ and stepup the ratio for the ram till it hits DDR 900. but i stil cant boot with tt settings.

Most of the time, i just boot, the nothing comes out and it restarts.
I got it to the part where it detects my USB configurations, but it'll just hang there..

Anyone can help?
 
Just to eliminate your RAM as the problem firstly have you set them to the manufactures recommended voltage?

If you are using 4 sticks then up your NB voltage a touch see if that helps

Finally unlink it from the FSB or slow the timmings down.. then try and boot
 
yeap, running it at recommended voltages, 1.8v for DDR800, 2.2v for DDR1000, so i guess at DDR900, 2.2v will be fine?

using 2x1gb only

what u mean by unlink it from FSB?
 
ah soz didnt read that bit :)

well if it boots at 3.4 DDR800 then I would guess it has to be your RAM causing the problems @ DDR900 as you say it wont boot at lower FSB on that speed?

I hard to say as I have no experience of that board... but if you can slow the RAM down and it boots then must be the RAM failing @ the higher speed.. as you say you have increased the RAM volts and up the northbridge volts a little if this doesnt work then only thing i can suggest is slacken the timmings to 5-5-5-15/18

hmm but this rams can go up till DDR1000, are there any settings that i can change that may be wrong?
 
well my GeIL is rated at 800mhz but it will go over 1000mhz but I have to run it at 5-5-5-23 @ anything over 950mhz

Again normally its a matter of changing the ram timmings or increasing the RAM/NB voltage, its hard to give anything but general advise as I do no anything about the BIOS of that board
 
could it be a faulty memory controller?

i tried setting fsb at 360, so it wont be a cpu hitting the wall problem,
ram ratio to 1:1.25 such that the ram runs at DDR 900, and set memory voltage to 2.2 as recommended by Crucial for speed at DDR1000.
