i'm using team group Xtreem 1066 ddr2, 2x2gb, haven't got bios shots though sorry.

i might be able to get around to grabbing some though

Not sure if I should post here or in a separate thread, but I tend to err on the side of posting in previously established threads.

Quick background on me: My first PC build (and my first OC), and my first time back to Windows in 8 years.

I did read the Intel Overclocking Redefined Guide and found it to be quite informative and along with this thread I think I know what I am doing, however I am having a few issues with my current system.

I can get my e5200 to 3.0GHz with everything stock, but my concern is that when I edit my RAM settings to anything other than AUTO my system will not boot, however it runs fine with the ram set to AUTO, however CPUZ lists my FSB/DRAM at 1:2 at 480MHz. The Intel Overclocking guide lead me to believe that I should shoot for a 1:1 ratio, so is this really a problem? I did pass Orthos 10m fine as well as SuperPi 32M with no errors. Am I interpreting CPUZ RAM info wrong or am I not understanding the Intel guide?

Also, I can't seem to get the e5200 any higher than 3.0GHz; any attempts at > 3.0GHz result in the system not starting/BIOS reverting to old settings.

Edit: I should add that I am finding the RAM setting in the Gigabyte BIOS to be really obtuse, so maybe someone could shine a light on that? I did do some Google searching on it, but the info seemed to be incorrect for me (what the poster said, when applied to my machine, lead to the computer not booting).

what mobo do you have ?

whats your voltage ?

you need to do a prime95 test, a quick google will get you that program.. one hour of the small fft's

Thanks for the reply and sorry for not putting all of the pertinent information in the body of the post.

MB is in my sig (GA-EP43-D3SL, running the BIOS that came on it, not sure what version)

Voltage (Vcore, correct?) is set to AUTO. CPUZ reports it as 1.152v with the 3.0 overclock. (shown in attached picture)

And I have ran Orthos and Prime95, and aren't they both the same thing? I didn't run the small fft test though (ran Blend), but I will give it a shot and report back.

Edit: Prime95 small fft test ran for 1 hour with no errors or warnings. Max CPU Temp 51 CPU 0, 50 CPU 1. Vcore still on AUTO, CPZ reports it as 1.152V.

Fixed. 1.362 is the max vcore that intel suggests to get the full life out of the chip, and lets be honest here, if I go through 2 e5200s running them at 4GHz at high voltage in the same time an e8400 would last, I'm still saving some money.

I have a P45 instead of a P43 but from what you're saying about the memory settings in the bios being confusing, I'm thinking we have the same bios settings in front of us. I was confused by those too, and there wasn't much help to be found with Googling.

Let me preface any advice I offer by saying 'I'm not an expert' first. There.

I know what you mean, but I would ignore all those places you've read online that talk about trying to attain the 'magical 1:1 ratio'. What you're aiming for is to run your RAM as close to its rated speed as possible- or slightly higher when you're ready to start overclocking your RAM. The info in your specs says you're running 800MHz DDR2 but with your FSB now set to 240Mhz, and using a 4.00 memory multiplier in your bios, you're actually running your RAM at 960 Mhz. You can see that in your CPU-Z screenshot ('DRAM Frequency: 480 MHz' * 2). This could explain why when you try to go further, your PC isn't posting.

At a FSB of 240MHz, you'd need to select the 3.33 memory multiplier in the bios to run your RAM at 800Mhz. And if you want to go further, you'd probably want to choose a lower multiplier (2.66 is next in my bios) and 'underclock' your RAM (run it slower than its rated speed of 800MHz) to be sure that any instability you encounter as you continue to raise your FSB is not going to be because of your RAM.

If your bios is like mine, and has the letters 'A', 'B', 'C', D' next to the memory multiplier numbers (see the screenshots in my post on the previous page), then I certainly understand your confusion and feel your pain, but I can try and tell you how I understand it, at least. If your bios isn't like that, then don't mind me at all.

Actually, it's 1.3625V. (If you're going to nitpick BlankThis, be prepared to be nitpicked back!)

And just because you feel you can afford to keep buying new, replacement E5200s, it doesn't hurt at all for BlankThis to remind anyone else who comes here reading this thread for info that overvolting your chip isn't 'safe' or 'what everyone does'.

And for a graph demonstrating why vdroop isn't the evil devil everyone here seems to think it is, check out: http://www.anandtech.com/cpuchipsets...spx?i=3184&p=5. If you set your Vcore in your bios beyond the maximum recommended voltage 'to get around the vdroop', you're setting your CPU up to be potentially spiked with high voltage. Whether this can cause damage, or how much, I don't know. But for those of us who can't afford to keep buying new E5200s, it's something to consider I think.

ok heres my voltages:

BIOS vcore: 1.38125v
cpuz v1.48: 1.352v
coretemp0.99.3 VID: 1.2250 v

location: toronto,canada, my roomtemp is pretty 'cool' and currently puter is idling at 44-45c, been on for like 2 days

so wats my Vdroop???

Thanks for the info and the welcome!

Our BIOS seems to be, more or less, the same. 2.66(A,B,C,D) 3.33 (A,B,C,D), etc. Upon your clarification of RAM settings and the "golden" 1:1, I went back and moved the divider to 3.33C, and I am now underclocking the RAM at 400MHz with a 3:5 ratio. Preliminary tests show everything to be ok.

I did try to reset the divider to 2.66C so I could push my FSB up more (aiming for 260FSB @ 3.25GHz and the system would not post. Then I took the RAM voltage off AUTO settings (running at 1.8v) and bumped it to 1.9v, still no post. Does this mean it is time to take the Vcore off AUTO, or bump RAM voltage more? (RAM timings are 5-5-5-15 (auto detected and what is specified by Gskill). Also are you leaving your (G) MCH Frequency Latch at AUTO?
