Hi :)

Yesterday I took delivery of a E5200, GA-EP43-DS3 and Arctic Freezer 7. I was under the impression that pretty much every E5200 would do 3.0GHz on stock voltages, is this correct?

I have the CPU voltage set to 1.25v (Default VID) and have tried cranking the FSB up from 200 to 240 (with a 12.5 Multiplier) and the system refuses to boot. What is a safe voltage to pump trough a E5200? I don't want to go frying my chip :)

I am new to this Overclocking malarkey so if I have done it totally wrong please excuse me!

Cheers,

Craig
 
stick the volts up to 1.4 and go up in smaller FSB steps, with the 12.5 multi thats a huge jump of 40fsb you did.
 
Put the chipset voltage up one notch. Also what memory do you have? As the default voltage will be 1.8v but some performance DDR2 will need to be set at 2.0 or 2.1v.
 
Thanks for the replies.

The RAM I am using is the OCZ 4GB 800MHz Vista Dual Channel Gold Series, I made a thread about it yesterday regarding voltages actually: http://forums.overclockers.co.uk/showthread.php?t=17946567

I have been reading a few threads and I think it may be the RAM Ratio as its on Auto at the moment, as I up the FSB of the CPU it ups the speed of the RAM (I think) but I don't know which option to change in the BIOS - I will have to check when I get home :)

I will also try upping the voltage slightly. Thanks for the suggestions, keep 'em coming :)

Yea, doubt u need to up the CPU voltage (vCore). Make sure the RAM is running at its rated voltage and take it off auto. The bios should then give u options for RAM multipliers and will show u the resultant RAM speed. Try to keep this as close to 800MHz as u can while overclocking the CPU, u can test higher RAM speeds once u have the CPU stable.

p.s. i wouldnt be too worried about upping the FSB in small increments, going straight in at 3.0GHz should be fine, once u get there perhaps go up in increments of 5-10.
 
Great, thanks for the help :) I will give this a try when I get home and update this thread with my progress!

Cheers,

Craig
 
It's more likely that your ram is above it's rated speed so that's causing it not to post. You should get 3Ghz on stock volts. Just make sure that everytime you increase the fsb you cheack to see what speed your ram is running at. You will probably need to change the fsb strap to NB and/or the dram frequency to keep your ram in spec.
 
Bit of an update...

The memory I bought was rated at 5-5-5-18 but both CPU-Z and my motherboard detect it at 6-6-6-18 - if I try and modify this to what it should be the system refuses to post. I did manage to get the system to boot with the F5 BIOS with the CPU at 3.0GHz (12.5x Multi, 240FSB) and the Memory at 6-6-6-18 but as soon as I updated to BIOS F9 the system again refuses to boot - I think its something to do with the extra memory options that BIOS introduces, not sure what settings to set them too.

I'll take a screenshot in a bit and you will see what I mean :)

Cheers,

Craig

Edit: Also, CPU-Z is showing my memory as 400MHz and it should be 800MHz (the BIOS is showing it as 800MHz too)

Hi again,

Looking at your memory thread, you will need to run this memory at 2.1v. Although the site says 1.8v, this won't run with reasonable timings at that voltage (not sure why they put that).

Remember that DDR2 will show up as either 400 or 800. It runs up to 400Mhz which is fine for most overclocks as the FSB of a E5200 is 200 anyway so you could double your CPU clock and would only just reach the default memory speed :).
 
Thanks for that info Duke - I didn't want to pump 2.1v through it incase I frazzled it but on your advice I stuck the voltage up to 2.1v and then this happened:



:D

Time to push a bit further I think. Thanks for the help everyone, no doubt ill be calling for more help in the future ;)

38ºC at full load :eek: plenty of headroom for more volts and more overclocking :D keep going dude

It hovers around between 38 and 41 on full load, very pleased with that :D I had a few problems with the memory running at 5-5-5-18 (as it says on the OcUK website) and I am now running it at 6-6-6-18 as that's what its suppose to be running at apparently! Going to push to 3.2GHz some time today :)
 
Make sure you're running the memory 1:1 with the CPU. In the BIOS set it to 200/400/800 (whichever is listed).

I cant see the option for that in the BIOS, I know the memory is running at 800MHz - is that what you mean? (Sorry, still new to this!)

You have to press Ctrl + F1 in Gigabyte's main bios page to get all the options up. System Memory Multiplier is the option you are looking for.

Trust Gigabyte to have secret hidden memory options :p

The value in System Memory Multiplier is "3.33C" and the FSB Strap is "Auto"
