Stable E8400 OC - stock voltages

Re: Stable E8400 OC - stock voltages

Hi,
I am a newbe to OC & this exact mobo-ram-processor...
I followed the OC details and got the rig to boot right up - thanks guys..

However - I see 2 thing which bother me. one - the ram speed in CPU-Z still shows 533, not 1066 (although the bios indicated 1066), why?

Also - I use Freezer pro -7 and still my temps are 39 idle and 50 load, is this normal?

Last thing, I notice you all disable USB discovery - I need that since I use external drives and thumb Drives regularly. why disable the USB discovery?

I'll appreciate the help

CPU-Z reports MHz, memory is Double Data Rate, so 533 X 2 = 1066.

What are you using to load the CPU?

USB Discovery? What motherboard? Mine is USB Storage, maybe same thing? I don't know.

Thank you capt proton, so now I know my memory is doing okay.
My mobo is UD3R - and you're right USB Storage - what's that for?

Most importantly - the Temps - all I used to 'load the CPU' was Flight Sim x... not much (I think).... also, I used PC Wizard to benchmark the system - same thing - temps run up to 50+. Also it idles at 39 - is that the norm?

I need to know if that's normal since I used the thermal pad which was on the Freezer pro, maybe I should use my silver thermal past instead??

Re: Stable E8400 OC - stock voltages

One more thing,
you all report 1:1 FSB:DRAM ratio mine is 3:4... why? what does it represent?

Re: Stable E8400 OC - stock voltages

USB Storage enabled is needed to boot from a USB Stick. I don't think it is needed for anything else.

1:1 is the emory multiplier, as is 3:4. In the BIOS, 1:1 is 2.00. Read this thread

Okay, so will going 1:1 give me a better performance?
I read the referred post and table - to get 1:1 I'll have to reduce my RAM to 800MHz (instead of 1066). I am not clear of the benefits to have 1:1 ratio.
Thanks for the info on USB storage, I'll disable that and maybe get a faster boot time.

Hard to explain in one post. Research is the way to find answers. I have read several articles that show that exceeding 1:1 does not really give that much benefit, as the bandwidth from the CPU becomes saturated and can't really keep up. However, there is nothing wrong with having the memory at other dividers to achieve whatever gain can be had, as long as you remain stable. as you raise your FSB, then, obviously, the memory strts to go faster. If the memory speed gets too fast and becomes unstable, then a lower memory divider will get the memory speed back in spec again.
That's all I am going to try to describe. Use the search function. You will learn much more that way.

Re: Stable E8400 OC - stock voltages

Funny, if you noticed throughout I didn't mentioned the word stability... with everything I did so far - the PC booted very stable, no problems at all - just a little increase in idle/load temps.
Anyway Capt ,thanks a lot for the clear explanation. I did try to search for this explanation but all I found was an even more confusing description... yours made more 'simple-sense' then all others.

I think that for now I'm set with my OCing, I found that with 400 fsb and no voltage manipulations my E8400 CPU keeps cool, stable and at 3600MHz. As to the RAM - I got it to be 1066 as it should @ 5-5-5-15 and minor voltage tweak from 1.8v to 2v. Runs very smooth and reasonably fast for me. I'll let it grow on me before I'll try to tweak this CPU any further (to 4GHz).

The best that go together.

Re: Stable E8400 OC - stock voltages

What's the latest BIOS being used for OC'ing? I see F9 has been out.

Re: Stable E8400 OC - stock voltages

Still on F7 here. I'm not experiencing any problems, so I'm reluctant to upgrade the BIOS.

You pull off 4Ghz or higher and stable yet?

Re: Stable E8400 OC - stock voltages

To be honest I haven't been able to devote the time I want to going for the 4.0. Now that the summer holidays are here I'll check it out.

Cool. I certainly appreciate what you do and that you are sharing it. Be great if you can hit 4.5. I tried but no luck. However, I don't know how to tweak what's necessary very well either.

Re: Stable E8400 OC - stock voltages

Just curious. I remember some setting having to do with Virtual Machine, or similar. If I'm going to install Virtual PC 2007 do I need to have this enabled and if so will this cause any issues with OC'ing? I thought it was recommended to disable this.

Anyone? (8/5/09)

Also, anyone update to a later BIOS? I think 9 is out now.
