Here is my setup:-

CPU = e2160
Mobo = DFI Infinity 975X
Ram = 2GB Geil 800Mhz DDR2
GFX = ATI Radeon x1800xt
CPU Cooler = Freezer 7 Pro

I am having trouble getting my e2160 past 2.5Ghz. I have tried dropping the Ram speed through all the different timings avaliable (800/667/533/400) however I can not get past 2.5Ghz.

I have also tried increasing the CPU voltage to the Motherboards maximum 1.35v but no joy. The system will fail to post if I attempt to go past 2.5Ghz/270FSB.

Any help or advise would be great.

Here are the current settings of my Motherboard:-

DRAM timing and config = Auto
PPM function = Enabled

Ratio and clock setting
FSB 800Mhz CPU enhanced mode = Disabled
Current CPU speed = 2260mhz
CPU clock ratio = 9X
CPU clock setting = 240Mhz
Current DRAM speed = DDR2 639
System memory frequency = 533
PCIE clock setting = 100Mhz
Sata clock sync = Fix 100Mhz

Voltage setting
CPU VID offset setting = default
Default CPU voltage = 1.31250 V
CPU VTT voltage = 1.35 V
DRAM Voltage setting = 1.90 V
NB chip voltae setting = 1.60 V

MISC
Auto detect PCI clk = Enabled
Spread spectrum = Disabled
Memory hole mapping = Enabled

Hi Marcus, yes I have updated to the latest bios as I also read that the bios for this Motherboard was touchy until the recent updates.

I have just had some luck, I increased my DRAM voltage to 2V and now I can clock past 2.5Ghz. What is the maximum voltage that can be put through the Ram?
 
My money is on 1.35V not being enough, but you need to eliminate the northbridgeas a source of the problem: drop the multiplier to x8, and try again. If it still fails at the same bus speed then it's the northbridge, if you can get the bus speed up until the CPU fails at the same CPU speed, then I'd bet that you don't have enough voltage.

im not sure with geil but my corsair dominator uses / needs 2.1 to id say ure about right there others might clarify what it will take , glad you can get past 2.5 ghz lets see some 3 ghz attempts :)

EDIT : also do what meridian has suggested as it could indicate a few problems that may need adjusting or you might have a bad ocing board :) not sure
 
Ok I dropped the memory down to 400Mhz and then went for 300FSB, however my rig fell flat on it's face, had to clear the cmos to get rig to boot back up. Will try what Meridian said. Will also try increaing the Northbridge voltage a small amount.

Cheers guys.
 
should be able to drop ya memory down more shouldnt ya ?

I can't drop the memory speed down any further than 400mhz. I used Meridian's advise and dropped the multiplier down to 8x, however my system still failed to boot using the same bus speed. Time to increase northbridge voltage? Also how safe is it to increase the memory voltage further? I think I am going to try increasing the memory voltage to 2.1V and the northbridge to 1.65V from 1.60V.

If anyone has any advise on whether I should or shouldn't go ahead with the voltage increases then please feel free to comment.

Here is a screenshot to show you where I am currently at.

Just tried posting with 280FSB to try and break 2.5ghz but my system failed to boot even with the memory running at 2.2V and the northbridge at 1.7V. Looks like 2.4ghz is my max clock. :(
 
whats your cpu voltage? my e2180 was stable. but it shot up very fast for any higher clocks.

I note you have a nice low VID. My e2160 is 1.325V. Try upping vcore to 1.4V and leave all other settings at stock. No need to tweak NB or RAM at this stage. Ensure RAM is loosened to 5:5:5:15 to eliminate latency issues at this stage.
 
My board doesn't allow me to increase my vcore any further, it has a max of 1.35V. I have to do some research on how to loosen and tighten memory timings as I don't know how to do it.
 
Ah, that may be the culprit if further tweaking doesn't reap any rewards. :( Although I would have thought you would be able to get a little higher with that vcore.

I would have thought so too.

I am also beginning to think that the limited vcore voltage is holding me back.

Thanks all the same for your help.
