E5200 Overclocking and performance comparison.

Well I got one of these the other day and straight out the box its running 3750mhz with the ram at 900(max my ram can handle) with 1.35ish vcore and a nudge on northbridge/vtt. 59ish max temps with a basic freezer. Very happy :) Going to have a mess with dropping the multiplyer and ram divider when i have time as I'm sure there is more to come out of it. Absoloute bargain imo!
 
Got mine nice and happy at 3.25Ghz. Obviously could push it further...3.4Ghz+ would be nice. Might try when I have free time :)
 
Excellent review there mate. I bought an E5200 on the basis of this for a build for a mate. Got 3.0ghz straight away and after a bit of "burn in" now running at 3.2ghz in an antec 300 so cooling isn't a prob but I'm still using the stock heatsink so thats gonna be replaced with summat better. Again, very infornative info mate, well done.:)
 
Great job buddy, surprised that you didn't get your E5200 further at those volts though. I have mine running at 4Ghz on 1.475v and have seen even higher clocked ones at those voltages.

Thanks for the comments guys. :D

1.475v is too much for a 45nm core. I could probably get mine stable with that voltage but there is no way i am killing this cpu. It's not worth it for 400 mhz. I killed a E8500 when they first came out and that was just with 1.52v.
 
Hi Pastymuncher - what's next ?

Finding a source for pasties in Scotland!! :D:D:D

This was just a one off really. I did this at the time that they came out as a lot of people were undecided on what to go with. I thought i may be able to help people decide by doing some real world test's. I also wanted a new toy. :D Any test's i do with my current cpu would'nt be comparable as i don't have the GT anymore. I really don't want to start from scratch again as this took several days to do and benching is really boring. I won't be buying any new hardware for a while now as my rigs do everything (and more) that i ask of them and i am very happy with them.

I am planning on making a Mountain Mods type case from scratch to house the main rig in. Going to be made from 1.5mm aluminium. Currently in the planning stages at the moment. I will be building a new radbox for my window mounted radiator at the same time. The "other half" wants something that does'nt stand out so much. I will be taking the opportunity to fit a new rad, Probably a PA 120.3/Feser 120.3 so that i can use lower cfm fans.

I clocked one for a mate to 3.75 GHz, 1.400v BIOS, CPU-Z showing 1.385 and temps 59/58 under 100% load. I'm under impression 1.4v is ok for 45nm, or is that still too high? :confused:

If so ill back it off to 3.6 GHz at 1.375v BIOS.
 
If these are similar to the E8400 (architecture, specs, etc) then I read that 1.4v-1.45v Vcore is about the max they'll take. i've a few posts from pl that they start to suffer electron migration above those voltages irrespective of cooling and any overclocks will start to degrade pretty sharpish. I reckon you're safe at a max of 1.45v Vcore, but any higher and degradaton might set in.
If I can get a decent cooler on this E5200 on me mate's, I'll try 1.35v Vcore and go for 3.6ghz. Incidentally, whats the highest fsb that these cpus can get to? I'm wondering if bandwidth performance would improve a fair bit.:)

Bang on. They are inded 45nm Wolfdale cores. 1.45v should be the max applied although i will not take mine past 1.4v. It's not nice having a chip die on you. :(

Mine actually hates high fsb's. I tried that while testing to try to run the ram at 1066. It will not go past 336-340mhz. I have seen someone do 420mhz but that was with a stupidly high 1.9v and phase cooling. When i was doing the test's i dropped the multiplier at 3Ghz (i think) and increased the fsb and with the extra bandwidth it did much better in the artificial benchies.

As you correctly say, it does'nt matter about what cooling you use, it will still end up dying. These things run pretty cool anyway. I only have a Freezer 7 Pro on mine and it's running nicely at 3.6Ghz at 27 degrees. I was playing with it earlier and i can now run it at 1.3v compared to the 1.325v it needed when doing the test's. That was a nice surprise. Maybe it will go further now. Might have a try over the weekend. :D

Concur with the FSB thing, i tried dropping the multiplyer and upping the FSB and seemed to hit a ceiling at about 345fsb regardless of how low a multi I used :( I've had the FSB higher with an old 2180 so I know its not the board
 


Thats mine at 3750. I know its only done 10mins of orthos but I'm too lazy to sit and watch it churning through it. Never have a problem with the PC doing what I want it to do. I did, however, have to bump the vcore a little more to 1.36 to get it totally stable. Happy though! :)

I'm happy there I think, i'd have to drop the divider and lower the memory speed to get anymore clockspeed wise :(

What make/speed memory are you using mate? This build I've done for a mate is running with 2 x 1gb Geil pc6400 @ 400mhz (240 x 3.33) in a gigabyte EP31-DS3L mobo (stunning mobo for the money btw).
 
Corsair 6400, CL5 stuff. Its running at 900mhz which is its limit, anymore and i get random bsod's or failed boots. All the info is in the screenshot above.

have you tried a lower memory divider and raising the fsb to see what results you get? Saying that would the higher fsb offset the lower memory speed you'd get?
